Abstract

A control device for a rail lifting mechanism to pass fishplates on a railway line automatically comprises an induction device used for detecting the fishplates, a distance measuring device used for measuring the traveling distance, and a controller, wherein the controller receives a detection signal of the induction device, sends a distance measuring actuating signal to the distance measuring device, receives a distance signal fed back by the distance measuring device, compares with built-in distance data, and then outputs an actuating signal to the rail lifting mechanism; the induction device is mounted to a detection trolley or the rail lifting mechanism; and the distance measuring device is mounted to the detection trolley or a main vehicle rack. The control device provides two fishplate detecting modes including a detection trolley detecting mode and a rail lifting mechanism detecting mode; both the detecting modes enable the rail lifting mechanism to pass the fishplates automatically when a rail lifting state is maintained in a screen cleaning operation process without manual intervention; and further, the defects that a steel rail falls off from rail lifting tongs and the like caused by limitation of the prior art are overcome, and the safety and the reliability for screen cleaning operation of a screen scarifier are improved.

Description

technical field [0001] The invention relates to a control device for a rail lifting mechanism to automatically pass over a fishplate of a railway line. Background technique [0002] Under the existing technical conditions, when carrying out ballast cleaning operations on railway lines, construction workers usually use the method of manually operating the clamps of the rail-lifting mechanism to open and close and lift, so that the rail-lifting mechanism can pass the ballast on the railway line while maintaining the rail. fish plate. Using this manual operation method not only needs to increase the corresponding job number, but also requires higher operating skills of the construction personnel. Once the operation is wrong, the rail will fall off from the rail clamp, which will cause damage to the line, excavation, running and other operating mechanisms in severe cases. Therefore, it is necessary to transform the existing technology so that the rail lifting device can detect...
