Embodiment 2

[0047] Such as figure 2 As shown, S1 includes the following steps:

[0048] S101, setting the control system to a memory mode;

[0049] S102, running the rail grinding train to the starting point of the linear grinding, and the control system records the position of the starting point;

[0050] S103, at the starting point, the control system controls the grinding motor of the grinding system to rise at the starting point by manually inputting a control command, and records the movement of the grinding motor;

[0051] S104, running the rail grinding train to the end point of the straight line grinding, and the control system records the position of the end point;

[0052] S105, at the end point, the control system controls the grinding motor of the grinding system to descend at the end point by manually inputting a control command, and records the action of the grinding motor.

[0053] By adopting the above method, the memory of the position information of the starting poin...

Abstract

The invention discloses a control method for automatic memory polishing of a rail grinding train main line and relates to the technical field of rail grinding train control. According to the control method, by memory of origin and end position information of a grinding operation section and actions of a grinding motor, a grinding control system automatically controls a grinding system to complete rail grinding in a set grinding mode in the back-and-forth envelope grinding process of the grinding operation section. Compared with the prior art in which the grinding mode needs to be set manually and the grinding control system is controlled manually by manpower to further control the grinding system to perform grinding operation, the control method is simpler in grinding operation, shorter in operation time, lower in labor intensity and higher in grinding accuracy.

Description

technical field [0001] The invention relates to the technical field of rail grinding train control, in particular to a control method for automatic memory grinding of a main line of a rail grinding train. Background technique [0002] In the process of rail grinding, it is necessary to adopt different grinding modes for a section of rail, that is, different grinding angles and different grinding powers, to perform reciprocating grinding, so as to realize the enveloping grinding of the rail and achieve the purpose of preventing and eliminating rail defects. [0003] The current implementation technology is to manually set the grinding mode at the starting point of rail grinding, and manually control the lifting of the grinding device while the train is running; reset the grinding mode at the end of the rail grinding, and manually control the lifting of the grinding device again when the train is moving in the opposite direction. According to the actual grinding needs, it can ...
