Chapter 130
The braking of a passenger train is that the train driver artificially affects the displacement of the train, including decelerating, not accelerating or stopping the train.Releasing or weakening the braking effect of a passenger train or locomotive that has already taken braking measures is called "relieving".

A complete set of equipment installed on each locomotive and vehicle for the braking and relief of passenger trains is collectively referred to as the "braking device" of the train. "Braking device" is commonly known as "brake".Performing the braking operation is often referred to simply as "upper brake" or "lower brake", and performing mitigation operation is referred to simply as "loose brake".

The technical principle of passenger train braking is more loaded down with trivial details and complexity than automobile, and this is because train is faster than automobile, and weight and volume are bigger.The friction between the car tire and the ground is rubber and asphalt, while the friction between the train wheel and the rail is special steel and high manganese steel. The contact between them is much smoother, which clearly shows that the brake of the car The friction force is bigger, easier and faster than the train, the train is more difficult to stop than the car, and the braking distance is much longer.

And the manpower brake machine on the passenger train is to use manpower as the driving force of the brake, and is manipulated and controlled with the rotation direction of the handwheel.This device is simple in structure and low in cost. It is the longest-used, most tenacious and most reliable brake in railway history.

In the early days of railway development, there were only such brakes on rolling stock. At that time, each car or several cars were equipped with a brakeman, and they were operated in coordination according to the driver's whistle. Because the braking force of the hand brake was weak, and The action is slow, requires more manpower, and is not convenient for the driver to directly manipulate, so it is quickly replaced by a non-manpower brake, and the hand brake becomes an auxiliary backup brake.

The hand brake on the passenger train is installed on the braking device of each passenger car. When in use, the handle is tightened to produce a braking effect.However, the braking force produced by it is much smaller than that of the air brake, and the braking process is also very slow. Therefore, the hand brake should only be used when the air brake cannot be used.

During shunting operations, use the hand brake to adjust the speed or stop the vehicle to ensure the safety of the operation; when the train or vehicle is parked on a sloped line, use the hand brake to prevent the train or vehicle from slipping away; Applying the handbrake action on the line prevents the vehicle from moving unintentionally.

In train crew jobs, the emergency brake valve, fire-fighting equipment, and hand brake must be aware of their location, ability, and use.In reality, the frequency of using the hand brake is very low. Passenger trains are used only after the locomotive breaks down or the catenary breaks down, and the train happens to be on a long downhill slope.

Liu Qun's team has done emergency drills on the use of hand brakes, and all staff are familiar with the use and working principles of hand brakes.Everyone knows that this kind of drill is like what the troops say—"the more you drill in peacetime, the less bloodshed you will have in wartime."

"Liu Che! Liu Che, I'm the train attendant. After receiving the driver's notice, the catenary in front suddenly lost power, and the train stopped temporarily. Now all trains are required to use human brakes to prevent the train from slipping away!"

Liu Qun, who was staring at the class, couldn't help but trembled when he heard it: How can this happen to anything?The once-in-a-lifetime event of using the hand brake also happened to me.Fortunately, after doing the drill in the early stage, Liu Qun also knew how to avoid panic.

Liu Qun used the walkie-talkie to call car 17, the conductor of the camping car: "Please tell all the off-duty male conductors to get up quickly, please be sure to be in place within 3 minutes, and take your seats according to the order of the cars that use the handbrake during the drill."

"Please 'horn' (train announcer) to make announcements to passengers. The power supply in front is faulty, and the temporary parking is stopped. Please sit in your seat and wait. If there is an emergency, please report to the conductor and apologize to the passengers."

Train K18 stopped temporarily between station G and station K.

Liu Qun thought to himself: Fortunately, my train is not a direct power supply train, but has a special generator car. If it is a direct power supply train, then all the power on the train is supplied by the locomotive from the catenary. If the catenary has no power, it will lead to The air conditioning, lighting, toilets and other facilities in the car were all paralyzed.The traveler is not easy to appease.

The deputy captain Zhang Lan also got up quickly, and Liu Qun reported to the dispatch emergency command center, the fleet, the passenger dispatcher of the group company, and the passenger transportation department respectively.

In less than 3 minutes, the male conductor, policeman, co-policeman, and vehicle crew who got up in the camping car were basically in place: "Car No. 1 is in place, car No. 2 is in place, car No. 18 is in place." Make sure that each car has a Gay men operate.

When reports came from the walkie-talkie that all the conductors in each carriage were in place, Liu Qun notified the train inspector. After the train inspector informed the driver, Liu Qun said to everyone through the walkie-talkie: "Everyone, please pay attention to the sound of the locomotive's whistle. Signal, tightening the handbrake whistle is "three short beeps", if the carriage behind the train can't hear clearly, you can listen to my password in the intercom." Liu Qun stood in front of the handbrake in No. 8 carriage , and issued an order in the walkie-talkie: "Quickly unblock and take the handle! There is no need to report if there are no special circumstances!"

The auditory signal of the railway system is a signal that expresses different meanings by the sound and the length of the sound emitted by different instruments.

Auditory signals mainly include the sound of horns, whistles, ringing pier, and the whistle of equipment such as locomotives.

The sound of the locomotive whistle, the long sound is three seconds, the short sound is one second, and the sound interval is one second. When the sound is repeated, the interval is more than 5 seconds.

The beep mode of start attention signal is one long beep, the beep mode of retreat signal is two long beeps, the beep mode of calling signal is three long beeps, the beep mode of alarm signal is one long beep and three short beeps, the signal of tightening the hand brake Three short beeps for the emergency stop signal, two short beeps for the emergency stop signal, and two short beeps for the relief signal.

The manpower brake operating handle of the passenger train compartment is located on the end plate at one end of each compartment.In order to prevent passengers from accidentally pulling out or turning during travel, according to the unified requirements of the head office, the passenger section has pasted a yellow self-adhesive seal with "Dangerous Do Not Move" on the card slot of the human brake. It is easy to use quickly, and the warning effect of this kind of seal is far greater than the sealing effect, as long as a little force can destroy the seal.

After unsealing, you need to pull out the handle of the manual brake from the card slot, pull out the two red handles, and hold one in each of the left and right hands. The handle of the hand brake is about 0.4 meters long, and both handles are painted red. Paint, which means danger, attention, and warning.

After about 5 seconds, the locomotive began to whistle, two short three beeps, as if to say: "Go, friends."
