Abstract:
Locomotives, grout cars, muck cars and segment cars are the common mining marshaling train which is used in shield tunneling. The traditional mining marshaling train control has a single pneumatic control, this will lead to brake time delay and cannot make the braking stepless adjustment. In order to solve this problem, we have changed the single pneumatic control by doubleacting pneumatic by adding a pressure piping on braking device. This will make the cylinder exhaust quickly, so that the delay problem can be solved. Meanwhile, the cylinders will get stepless air press to make the braking controllable. It will be greatly improve the reliability of the locomotive while braking, and can avoid the braking out of sync.
Key words: train marshaling, pneumatic braking, rehabilitation
