Coal mining machine is a large-scale mechanical equipment integrating mechanical, electrical and hydraulic. The underground comprehensive mining equipment of coal mine mainly includes hydraulic support, scraper conveyor and coal mining machine. Among them, hydraulic support is used to support the roof; scraper conveyor is used to transport materials, and the pin rail of scraper conveyor provides running track for coal mining machine; the body of coal mining machine is equipped with travel gear, traction motor and rocker arm, the travel gear is meshed with pin rail, and the traction motor is used to drive the travel gear to rotate so that the coal mining machine can move along the pin rail. At present, due to the harsh working environment of coal mining machine and the lack of protective measures at the left and right traction motors of coal mining machine, it has great limitations in use and installation.
