[0002] With the National 973 Program "Key Basic Research on Unmanned Mining Equipment in Deep Dangerous Coal Seams", the "863" Program Key Funding Project "Remote Control Technology and Monitoring System for Coal Shearers", the National Development and Reform With the development of large-scale national coal mine intelligent equipment projects such as "Control System Project", more and more attention has been paid to the automatic control of heavy equipment on the fully mechanized mining face, and the requirements for its control are also getting higher and higher. As far as the current research status is concerned, for The motion control of the scraper conveyor involves the push control part of the electro-hydraulic control system of the hydraulic support. When pushing the scraper conveyor, due to the bidirectional constraints of the chain connection between the scraper conveyors and the push The pressure limit of the required hydraulic pump, in order to minimize the control time of pushing and sliding, it is necessary to reasonably control the motion control sequence of the scraper conveyor, but there is no relevant research on the motion control sequence of the scraper conveyor.
In addition, at present, when the scraper conveyor is pushing, it can only be controlled in stages, that is, "one-key control" is not possible. The operator needs to constantly update the control strategy according to the current pushing situation, and use the pushing of the hydraulic support. The hydraulic cylinder is used to push the scraper conveyor, and the workers have a lot of repetitive work and high labor intensity, which is not conducive to the development process of "fewer people" in the fully mechanized mining face

Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] Such as figure 1 As shown, a scraper conveyor push movement sequence control system of the present invention includes three parts: the scraper conveyor body, the hydraulic support electro-hydraulic control push displacement acquisition subsystem, and the scraper conveyor movement sequence control subsystem. The motion sequence control subsystem of the scraper conveyor is installed on the scraper conveyor. In addition, it also includes a hydraulic support pushing hydraulic cylinder connected to the scraper conveyor; the hydraulic support electro-hydraulic control pushing displacement acquisition subsystem is connected with The push hydraulic cylinder of the hydraulic support is physically connected so that the hydraulic support can push the scraper conveyor.
[0030] The hydraulic support electro-hydraulic control pushing displacement acquisition subsystem includes a...

The invention discloses a control system and method of a pushed and slipped motion order of a scraper conveyer. The system comprises a scraper conveyer body, hydraulic support pushing and slipping hydraulic cylinders connected with the scraper conveyer, a hydraulic support electrohydraulic control pushing and slipping displacement acquisition subsystem and a scraper conveyer motion order control subsystem. The hydraulic support electrohydraulic control pushing and slipping displacement acquisition subsystem is physically connected with the pushing and slipping hydraulic cylinders of hydraulic supports. When the hydraulic supports push and slip the scraper conveyer, according to pressure of hydraulic pumps and the limiting condition of the maximum displacement difference between middle troughs of the scraper conveyer, the pushed and slipped motion order of the scraper conveyer is reasonably arranged, the scraper conveyer gently moves, and steel impact between adjacent middle troughs of the scraper conveyer is reduced; the pushed and slipped time of the scraper conveyer is reduced, and the pushed and slipped efficiency of the scraper conveyer is improved; and the linearity of the pushed and slipped scraper conveyer is increased, and steel impact and friction between a coal mining machine and the scraper conveyer are effectively reduced.
