Train dead-hooking treatment system and method for

Abstract

The invention discloses a train dead-hooking treatment system and method. The train comprises a plurality of heavy train sets. The train dead-hooking treatment system comprises a train dead-hooking alarming device and a control device, wherein the train dead-hooking alarming device is used for sending signals which express a dead-hook phenomenon between the adjacent two heavy train sets in the plurality of heavy train sets; the control device is connected with the train dead-hooking alarming device, and is used for receiving the signals which express the dead-hook phenomenon between the adjacent two heavy train sets in the plurality of heavy train sets, and controlling a positioning car to stop in the condition that the signals which express the dead-hook phenomenon between the adjacent two heavy train sets in the plurality of heavy train sets are received; and the positioning car is used for drawing and positioning the heavy train sets. With the adoption of the dead-hooking treatment system and the train dead-hooking treatment method, not only can the defects in the prior art of components damaged by overloading and train off-the-road and turnover phenomena be avoided, but also the huge impact brought about by scram of each component in a high-speed operation state can be avoided, the security of equipment can be ensured, and the fault treatment efficiency further can be improved.

Description

technical field [0001] The invention relates to the technical field of engineering, and more specifically, to a system and method for treating a dead hook of a train. Background technique [0002] The dumper system pulls and positions the heavy vehicles by the positioning vehicle, and then positions the two heavy vehicles on the platform through the pusher, and at the same time positions the empty vehicle that has been dumped. The automatic cycle process of the positioning vehicle is as follows : Locating the arm of the vehicle → connecting the heavy train → opening the first wheel gripper → to the normal unhook position → closing the first wheel gripper → waiting for the operator to remove the hook → to the handover position → closing the second wheel gripper → lifting the hook Pin → to the end position → the positioning car lifts the arm → returns to the drop arm position → the positioning car drops the arm..., a cycle that goes round and round. However, due to the failur...

AI Technical Summary

Problems solved by technology

However, due to the failure of the hook head of some trains or the inflexibility of rust, after the positioning vehicle pulls the heavy train to the unhooking position, after the operator unhooks normally and presses the button of "the positioning vehicle continues to move forward", the train's dead hook often occurs. The phenomenon that the hook cannot be removed (that is, the train hook pin has been removed on the surface, but in fact the internal fault of the hook head has not been removed)

At this time, the positioning car should have towed two heavy vehicles to move to the second clamper, but because the hook was not removed, the positioning vehicle pulled the entire column of heavy vehicles and moved forward with the wheels clamped by the first clamper. , resulting in severe overloading of the positioning car, overcurrent tripping of the frequency converter, serious damage to the reducer due to a force greater than the rated torque, and accelerated damage to the arm and hook of the positioning car.

What's more serious is that because the first wheel gripper is in the closed state, it is very easy to cause the train to run over the first wheel gripper, thereby causing the accident of the train falling off the track.

In addition, if the dead hook phenomenon is found and the emergency stop operation is performed on the positioning car, it will not only seriously affect the unloading efficiency, but also cause a great impact on the equipment because the dumper and cart are running at high speed at this time
