The train driver in the courtyard

Chapter 528 The idea of ​​electric sewing machine, Wang Mudan’s grievance

It was already past five o'clock in the afternoon when Li Aiguo ended the life-study meeting.

"Apprentice, let's go do some small work."

Huang Jing was carrying an enamel basin and was about to take a bath.

Seeing Li Aiguo bring a bottle of red paint from the dormitory, he quickly put the basin back and followed him.

"What are you doing, master?"

"You'll find out later."

When the two arrived at the station, train No. 131 had already undergone simple maintenance.

Team leader Zhang, who was in charge of maintenance in the maintenance workshop, greeted Li Aiguo with a smile.

"Driver Li, are you going to fiddle with those screws again?"

"Yes, practice brings true knowledge. If we are careful in our daily lives, we may avoid many accidents."

Li Aiguo handed Team Leader Zhang a cigarette, got under the car, took out a brush, dipped it in red paint, and applied it on the connecting rod screw caps under the car.

The bottom of the car was covered with oil and dirty everywhere. Huang Jing, wearing a clean uniform, squatted down and got in without any hesitation.

Seeing Li Aiguo's behavior from the lower part of the car, Huang Jing's little face was filled with doubts.

"Master, what's the use of paint on this?"

There were several screws in the gaps, and there were connecting rods blocking the outside. Li Aiguo handed the paint bottle to Huang Jing.

He took a brush, stuck out his butt and stretched out the pen holder, and applied it carefully.

While busy, he explained: "These screws are used for fixing. If the screws are loosened, it may be dangerous while driving.

But there are a lot of screws, hundreds of them, and it would be a waste of time to check them one by one before driving."

He took the brush and pointed at a screw cap that had been painted before: "Look at this screw cap."

Huang Jing poked her head out from behind his butt and saw that part of the bolt under the screw cap was not painted.

This is enough to indicate that the screw is loose.

The train was inspected by the maintenance workshop just now, but this was not discovered.

Looseness is difficult to spot without paint marks.

So when driving tomorrow, this screw may fall off in the bumps.

Thinking of this, Huang Jing couldn't help but give a thumbs up: "Master, your method is really good."

"Learn to be a train driver. It's not easy to become a train driver. If you want to be able to drive and repair a car, you have to know the train situation in advance."

Li Aiguo took out a wrench from his waist, handed it to Huang Jing, and motioned for her to tighten the screw cap.

While Huang Jing was busy, she continued: "I will be on a business trip in a while. You will be responsible for checking the paint on the screws every day, and then write down the number of times each screw is loose."

"Why do you need to record the number of times, master?" Huang Jing rested on the ground with one arm and held a wrench in the other hand, but she turned around to ask without delay.

Li Aiguo said: “These easily loosened screws can be regarded as design problems. When the amount of data is sufficient, we can provide opinions to the manufacturers through the maintenance department.

I hope they take into account the tendency of these screws to loosen while driving when designing the screws. "

It is prudent as a train driver to observe the paint in front to determine whether the screws are loose.

Now improving the screws by recording data has gone beyond the scope of the train driver's job.

Huang Jing felt that she somewhat understood why her master had received so many honors within a short period of time after entering the maintenance section.

"Master, don't worry, I will definitely write it down for you."

After tightening the screws, Huang Jing was so tired that she was sweating profusely. She raised her hand and wiped her chin, leaving a black oil stain on her fair chin.

Not only does it not look ugly, it actually adds a bit of the true character of working people.

Li Aiguo thinks this apprentice is pretty good.

He painted all the screws, went to the bathroom in the locomotive depot, washed up, and walked out of the bathroom with the enamel basin. It was already dark.

Huang Jing had been waiting at the door of the bathroom for a long time, took the enamel basin, pursed her lips and said, "Master, let me wash these dirty clothes for you. It's getting dark, and my wife must be waiting at home in a hurry."

In these days, it is common for apprentices to help their masters wash clothes. Li Aiguo did not refuse and left the locomotive depot on his bicycle.

When they returned to the courtyard, Chen Xueru had already returned from get off work.

Seeing him coming back with so much fine white noodles and soybean sprouts, I was a little surprised and asked: "Brother Patriot, why are the locomotive dept so generous this time?"

She reached out to take the bag, fetched a basin of cold water, wetted a towel and wiped Li Aiguo's face.

The cool towel brushed against my cheeks, easing away the fatigue of the whole day.

"I have to go to the Railway Research Institute to perform a task in two days. These supplies can be considered as funds."

"It would be great if we don't leave the capital."

Chen Xueru immediately became happy when she heard this, and whispered softly: "Counting the days, the ovulation period should be in these two days."

Liang Ladi gave birth to a daughter, her sister-in-law gave birth to a son, Huang Shuxian was about to give birth, and Feng Nan's belly was also growing. Friends around her were either preparing to have children or had already given birth.

Miss Chen feels a lot of pressure now.

"Don't worry, with your figure, you can definitely give birth to several children." Li Aiguo saw the look in her eyes, how could he not understand what she was thinking.

He pulled Chen Xueru onto his lap.

"No, it's still daylight now. It's so embarrassing to be seen by others."

Chen Xueru struggled to stand up and brought over the dandelion tea that had been cooled long ago.

"This is the dandelion that Ermao picked on the mountain. It is said to be the most refreshing and relieve the heat."

"Picked by Er Mao."

Li Aiguo took a sip. The dandelion tea had a faint bitter taste in his mouth, and then the bitter taste turned into a unique fragrance.

"How is the situation of the Nanyi family?"

Chen Xueru was busy in the kitchen, while Li Aiguo drank tea and leaned on a chair.

"It's not bad, but it's hard to buy nutritional supplements, and Liang Ladi has lost a lot of weight these days.

Nowadays, thrift is encouraged in the streets and large banquets are not allowed. Nanyi's extra income is also much less. "

Chen Xueru hesitated for a moment and poked her head out of the kitchen.

"Brother Patriot, there are more soybean sprouts this time. Even if we leave some of it for Aunt Liu, we won't be able to finish it. Otherwise, I'll give some to Liang Ladi."

"Just yesterday, Liang Ladi learned that my sewing machine had a thread jam, and she specially repaired the sewing machine for me. It cost a lot of materials, but she didn't take the money."

Chen Xueru is a kind-hearted girl. She and Liang Ladi are still good sisters and want to help her.

"This is what it should be, you just give it away."

Li Aiguo was not a stingy person and agreed immediately.

A flash of inspiration flashed in his mind, and he suddenly paused for a moment to look at the sewing machine.

If the sewing machine was changed to an electric one, wouldn't Chen Xueru be able to save a little effort?

Chen Xueru only sews clothes occasionally and uses a sewing machine every day in the tailor shop.

If you replace it with an electric sewing machine, the efficiency will definitely be greatly improved.

Man, just do it!

The principle and structure of electric sewing machines are relatively simple.

To transform this thing, Li Aiguo, as a mechanical master, did not need to use the system at all.

After eating, I sat at the writing desk, spread out a piece of drawing paper, and got busy with a pencil square.

Chen Xueru put away the dishes and wiped her hands. She originally planned to go to the park with Li Aiguo.

Seeing him busy, he asked curiously: "Brother Patriot, what are you painting?"

Li Aiguo said: "Electric sewing machine."

"Electric sewing machine."

This was the first time Chen Xueru heard this term. After tasting it carefully, her dark eyes suddenly widened.

She said excitedly: "Is it a sewing machine that can rotate automatically without pedaling?"

"You see, there is an electric motor installed on the sewing machine, and it can be driven by plugging it in."

"This is great!"

The electric sewing machine is the most inconspicuous of all Li Aiguo's inventions, but it is the one Chen Xueru looks forward to the most.

It may seem easy to operate a sewing machine, but if you repeat the simplest action thousands of times, it will become a heavy burden.

Chen Xueru comes from a tailoring family and understands this deeply.

Chen Fangxuan has been using sewing machines for decades. Every night when he lies in bed, his legs are numb.

As he gets older, it becomes even more difficult for him. He has developed varicose veins in his legs and often needs to apply Tongrentang plaster.

"Brother Patriot, hurry up and draw a picture, and I'll get you some tea."

In order to be able to build an electric sewing machine as soon as possible, Chen Xueru felt that the rough man should be served comfortably.

She first gave the rough man a beating on his back, then fetched a basin of hot water and rubbed his feet.

Li Aiguo was dumbfounded for a moment.

He is drawing a picture.

It's just that Miss Chen is so active, so we can't attack her.

Li Aiguo could only draw on white paper with a pencil in his hand while receiving services from a master of romantic techniques comparable to Hong's.

Fortunately, the structure of the electric sewing machine is simple, so it does not delay things.

Li Aiguo considered that there is no particularly large market for electric sewing machines and did not redesign the sewing machine.

Instead, an electric motor device was added to the existing structure, and devices such as needles, bed needles, plate hems, and thread reels were added.

Among them, the cable reel is the most important equipment.

It controls the tightness of the sewing thread by controlling the yarn tension to achieve the best sewing effect.

The difficulty of the design also lies in the cable reel.

In later generations, the thread reel was successfully developed after tens of thousands of experiments, which was related to whether the sewing machine was easy to use.

Li Aiguo stands on the shoulders of future generations, so naturally he doesn't need to go to so much trouble and can just mark a few data.

Even so, a simple drawing took three hours to complete because of the thread reel.

pat.

The pencil rests on the table.

Li Aiguo stretched out and looked at Chen Xueru, who was rubbing his feet.

"Daughter-in-law, please go to Liang Ladi's house, deliver the bean sprouts, and invite Liang Ladi over."

"it is good."

Chen Xueru wiped her hands, poured out the foot washing water, and carried the bag out of the house.

At this time, there were many people sitting in the middle courtyard enjoying the shade. Everyone could chat for hours with an enamel jar of tea.

It was after ten o'clock when the weather cooled down, and I went home to sleep contentedly.

Jia Zhang and Jia Dongxu were also sitting at the door enjoying the cool weather and saw Chen Xueru carrying soybean sprouts and walking towards Nan Yi's house. Jia Zhang's triangular eyes squinted: "This Chen Xueru is really ignorant. My old lady is so old. Instead of giving it to me, she gave it to Liang Ladi!"

Jia Dongxu was afraid that others would hear it, so he hurriedly stopped Jia Zhang: "Mom, please stop making trouble, otherwise the street office will not be able to spare us."

A while ago, Jia Dongxu was dealt with by the police station because of the incident of Nan Yi's family losing a sheep.

Not only was he inspected in front of all residents in the neighborhood, but he was also punished in the steel rolling mill.

I'm currently on "probation," so I have to be careful to avoid getting into trouble again.

Although Jia Zhang was not convinced, she had no choice but to shrink her neck and swallow the rest of her words.

Qin Huairu breathed a sigh of relief when she saw this scene from the side.

The last time the police station dealt heavy blows, she had some objections at the beginning, but Jia Dongxu was punished and she didn't dare to play cards anymore.

Jia and Zhang didn't dare to cause trouble anymore, and the Jia family's life seemed to be much better.

But the soybean sprouts were so tempting. Qin Huairu had never eaten soybean sprouts before.

Now Li Aiguo is tired of eating soybean sprouts and has given up.
There was a hint of bitterness in Qin Huairu's heart, and the originally slightly cool air seemed to become hotter.

Chen Xueru smiled and greeted the residents all the way to Nan Yi's house.

Liang Ladi had just fed Nan Xiaoying, and when she saw Chen Xueru coming to the door with a bag of bean sprouts, she immediately understood her intention and quickly wanted to refuse.

"Sister Liang, this is a gift from my family, Aiguo, to you. It's not for nothing. Aiguo may need your help for something, and he's waiting for you at home."

"Even if it's to help, there's no need to give such an expensive gift."

Liang Ladi wanted to refuse, but Nan Yi stopped her.

"Ladi, you are just about to recuperate, so let's take it first."

Liang Ladi felt that the Li family had helped her too much and was afraid she would not be able to repay them.

She is not a pedantic person. Now that she considers the reality, she accepts the bean sprouts.

She handed Nan Xiaoying to Nan Yi, told the children of Da Mao and Er Mao to do their homework, and then followed Chen Xueru to Li's house.

"Master Li, what do you want me to do?"

Under the dim light, Li Aiguo placed the drawings on the table.

"Can you modify my sewing machine according to the drawings?"

"Modification."

Liang Ladi, a fourth-level mechanic, suddenly became energetic.

In these days, first- and second-level workers can do the job as long as they have the hands and feet, but all senior masters have real abilities.

Looking at the drawings, designing machinery is easy.

Liang Ladi picked up the drawing and just glanced at it twice before she understood Li Aiguo's intention.

"Installing an electric motor on the sewing machine and driving it through a belt, Driver Li, is such a good idea, why didn't I think of it?"

Liang Ladi once wanted to install a grinding wheel on Li Aiguo's bicycle several times, and also personally participated in the design and construction of the Yanjia lighting project.

She considers herself a great inventor and has used sewing machines several times. She has never thought that sewing machines can be driven by electricity.

Sometimes many inventions do not require very clever design or advanced knowledge, but just an idea.

As a time traveler, Li Aiguo is indispensable for ideas.

Liang Ladi held the pencil and calculated for a while, her frown slightly relaxing.

Li Aiguo asked: "How about it? Can it be reformed?"

"Of course it's no problem. We have obsolete electric motors, belts, angle irons and other things in the factory. You can buy them back at the scrap price. Just borrow another welding machine and buy some wires."

Before Liang Ladi started the renovation, she was thinking about saving money for Li Aiguo.

Li Aiguo calculated carefully and found that it only cost less than eight yuan to modify an electric sewing machine.

This deal is really a good deal.

"Liang Ladi, the renovation project is relatively large. You have worked hard and deserve to be paid for your labor."

Li Aiguo took out two dollars from his pocket and handed it to Liang Ladi: "Take this money and treat it as wages."

"You can't accept it. You have helped my family so much and saved Ermao's life. If I accept it, will I still be a human being?" Liang Ladi took two steps back as if she had been hit by a soldering iron.

Chen Xueru knew her temper, so she took the money and stuffed it into her hand.

"Sister Liang, you also know your patriotic temper. If you don't accept it, he won't give you this job."

"This"

A wave of heat surged into her heart, and Liang Ladi bit her lip and nodded heavily.

"Don't worry, I will make the sewing machine perfect."

When mentioning this matter, Li Aiguo thought for a while, took the manuscript paper, drew a device and handed it to Liang Ladi.

"When you modify it, add this thing under the needle plate behind the conveyor belt to protect the wire reel. The parts in the wire reel should be glued to the box with phenol resin adhesive.

Phenol resin adhesives can be obtained in the maintenance depot, so you don’t have to worry about this. "

Hearing the term phenol resin adhesive, Liang Ladi's expression became solemn.

Phenol resin adhesive is a kind of chemical glue, and its function is similar to that of 502 in later generations.

These days, only the sulfonation method is produced by Jinxi Chemical Plant. Not only is the price high, it is also very difficult to get hold of it.

This device seems to have no meaning. It is just an anti-disassembly iron box. Its only function is to prevent others from disassembling the cable reel.

"Brother Patriot, are you worried that someone will secretly dismantle the electric sewing machine we modified? Who is so boring?"

Liang Ladi had some difficulty understanding Li Aiguo's thoughts.

The cost of adding an additional anti-disassembly iron box will be much higher.

And it also uses a rare thing like phenol resin adhesive, which is like taking off your pants and farting.

"You don't need to understand this, just follow the plan."

"Okay. I happen to be on half-time break right now, so I have a lot of free time. However, this thing is quite complicated. It will probably take more than ten days to complete the transformation."

Seeing that Li Aiguo insisted on installing a tamper-proof iron box on the sewing machine, Liang Ladi, as Party B, could not say anything more at this time and agreed.

Drawing drawings and communicating with Liang Ladi took several hours, and it was already late at night.

As soon as Li Aiguo lay on the bed, he saw Chen Xueru walking in wearing a yoga suit.

The bright red yoga clothes are tightly wrapped around the exquisite and clear body, and the curves are more rounded. One glance makes people feel dazzled and fascinated.

"Brother Patriot, thank you so much for the electric sewing machine."

While speaking, Chen Xueru stretched out her toes, twirled a strand of black hair with her fingers, put it on the corner of her lips and bit it gently, saying with a half-smile, "Let me thank you today~"

Time passed quietly.

The shadow of the old camphor tree in the yard gradually lengthened.

At this time, we were in a side room of a large courtyard close to the locomotive depot from the front door.

Wang Mudan turned on the light and nestled against Yang Yi's chest.

Thinking of what happened over the past half month, Wang Mudan felt a hint of bitterness in her heart.

Since arriving in the capital, Wang Mudan has fallen in love with this city.

There are concrete floors everywhere and bustling shops everywhere.

Movies are shown every day in the cinema, and even the air is a bit sweeter than that at Sentie.

At that time, Wang Mudan made up her mind that instead of attending a class to receive passenger transportation training, it would be better to find an opportunity to stay in the capital.

Wang Mudan has a clear understanding of her own.

She has no education or ability, and the only thing she can rely on is her beauty.

Relying on this advantage, Wang Mudan became a railway employee step by step from a villager.

Now she still has to use this advantage to achieve her goal of staying in the capital.

It's just that the Qianmen Locomotive Depot has been undergoing a month-long rectification since the incident of deputy section chief Liu and Liu Chunming fooling around.

Every weekend at the life-study meeting, the officers in the education office will explain this example to the leaders and employees.

Deputy Chief Liu had a bright future at a young age, but now he was assigned to work at a small station in the steel rolling mill, and his end was extremely miserable.

So when faced with Wang Mudan's overtures, the leaders and employees fled away as if they had encountered a beautiful snake.

Of course Wang Mudan didn't know this.

I thought that the leading employees of the Qianmen Locomotive Depot had high ideological consciousness, and when they were about to retreat, they met Yang Yi.

Yang Yi himself is only a temporary worker at the Harbin Locomotive Depot.

In order to go further, I married the daughter of a director of the Harbin Locomotive Depot.

His daughter-in-law is average-looking and very conservative, and there is no way she can compare with the beautiful Wang Mudan.

Yang Yi was hailed as the rising star of the Qianmen Locomotive Depot. Although Wang Mudan looked down on him, he could only make do without a better goal.

The woman chased the man, but under Wang Mudan's deliberate approach, Yang Yi quickly surrendered, and the two of them got into the locomotive in disgrace.

At this time, Wang Mudan's face was flushed, dripping with sweat, her black hair stuck to her forehead and cheeks, and her red mouth was slightly open, panting.

"Brother Yang, you are really amazing."

If Yang Yi didn't know her age, she would have thought she was a little girl.

"That's who I am, Yang Yi! The best train driver!"

Yang Yi stretched out his hand, patted Wang Mudan's cheek twice, and said proudly: "As long as you follow me, you won't have to worry about being popular and drinking spicy food in the future."

Wang Mudan curled her lips secretly.

It only lasted five minutes, and I said you were fat and still had trouble breathing.

But Wang Mudan wanted to act obedient at this time, and slapped Yang Yi with a rainbow fart.

When the time came, Wang Mudan's face suddenly showed a hint of grievance: "Yang Yi, when will you marry me?"

The beautiful atmosphere was broken, Yang Yi became cold instantly, sat up straight and pushed Wang Mudan aside.

He lit a cigarette, took two puffs lightly, frowned and said, "Didn't we agree, Peony, that we can't get married for the time being?"

"You also know that I have a wife, and now is a critical period. If I can win this year's overall advanced driver, I will definitely be a leader in the future."

"If we get divorced now, all of this will be over."

As Yang Yi spoke, he nibbled twice on Wang Mudan's face with his stubble-covered mouth.

"Mudan, don't worry, give me another half year, and I will definitely divorce that yellow-faced woman."

The disgusting stench spread all over the place, and Wang Mudan was almost vomited.

While supporting Yang Yi's head, he said depressedly: "I also want to give you time, but I will be expelled from the study class soon."

"Expelled?"

Yang Yi, who was in the midst of excitement, was showered with cold words.

"The monitor in the study class is not an idiot, how could he fire you?"
