The spring breeze blows
The willow branches spit green
Wild mushrooms in the mountains
It ushered in a lush growth season
Even the rails grew "iron mushrooms"
There are also people who provide them with exclusive services
What's going on?
I'll take you to take a look
Look at these deceleration tops, all of them are big and thin, like 'mushrooms' that grow on steel rails?
In the marshalling yard of Baotou West Railway Station
Foreman Zhao Yun led the equipment workshop to decelerate the top work area
6 employees
Started the spring inspection and spring inspection of the deceleration top equipment
Baotou West Railway Station is the largest regional marshalling station in the central and western regions of Inner Mongolia, and the spring driving equipment ushered in a new round of "comprehensive physical examination".
Through the careful and meticulous "pulse checking" of the employees, all kinds of driving equipment run well in sandy days, "cold spring" and other weather conditions, and lay a solid equipment foundation for transportation safety.

It is the main place for efficient train marshalling
A deceleration top shaped like a mushroom
It is a key equipment to regulate the walking speed of the vehicle
Knowledge points
The function of the deceleration top: when the wheel passes over the deceleration top, the compressed deceleration top will give the wheel a reverse resistance to slow it down, and the deceleration top will bounce up immediately after the wheel leaves to prepare for the next deceleration. In this way, the vehicle has run over enough deceleration tops, and the speed slowly decreases.
Freight trains are handled on a daily basis
More than 11,000 vehicles
Baotou West Railway Station marshalling yard
The 43 shunting lines are evenly distributed
9,660 units of reduction top equipment
Due to the all-weather nature of railway transportation
These devices need to be used 24 hours a day
Ultra-high frequency of use
This makes internal parts susceptible to wear and tear
If maintenance and repair are not carried out in time
There is a high probability of a security incident
therefore
Precise maintenance of the reduction top
It has become the key to ensuring the safety and efficiency of shunting operations
Today, we will inspect and maintain the 448 deceleration jacks in the downward marshalling yard, and whether the deceleration jacks are faulty or not, you can know by stepping on them, and the young people in the work area call this 'stepping on mushrooms'.
Zhao Yun, who has been engaged in the maintenance of deceleration jacks for many years
The experience is very rich
I saw him gently step on a deceleration top
With the leg steady force
The deceleration roof slowly descended
In the reduction top maintenance operation
Two maintenance workers are in charge of a strand
One from the beginning and one from the tail
Judge by the feeling of your feet
Whether the reduction top is faulty
For them
Repeated "stepping on the top" work
It was a double test of physical strength and patience
It's a bad top, it's lost its deceleration and must be dealt with immediately.
Through meticulous overhaul
A deceleration top that does not rebound was found
Maintenance worker Xiong Xin immediately skillfully disassembled and replaced
Take the fault top back to deal with it
And record the repair process item by item
To maintain the safety of the equipment in the future
Accumulation of data
Operators insist on fine inspection and careful repair
Make full use of the "combination of dynamic and static".
Comprehensive equipment management system
By dynamic inspection during the overhaul process
Static observation during use
Make every effort to ensure the safety of your equipment
Escort the safe operation of trains
In March, it is warm and cold
A busy marshalling yard at Baotou West Railway Station
Reduction top after overhaul
Issued under the crushing of the wheels
The crisp sound of "tick, dodo".
It's like a forward movement
