[0035] The working principle of the present invention is as follows: first, the hydraulic support is placed on the electric rail car 3 and operated by the controller. The electric rail car 3 transports the hydraulic support to the U-shaped mounting frame 2 along the track, and then adjusts the height of the high-pressure flushing gun 9 and the distance between the gun head and the side of the hydraulic support according to the different models and sizes of the hydraulic support.

At this time, the flushing water can clean the hydraulic support in the horizontal direction through the gun head of the high-pressure flushing gun 9. At the same time, the start of the stepper motor 401 drives the lifting rod 404 to lift and lower in the height direction of the mounting frame 2, thereby realizing the horizontal cleaning of the entire surface of the hydraulic support;

[0037] When cleaning the hydraulic support longitudinally, the controller controls the displacement motor 506, the adjustment motor 702 and the stepper motor 401 at the same time, wherein the displacement motor 506 drives the displacement plate 501 to move along the length direction of the lifting rod 404, that is, to move along the horizontal direction of the hydraulic support, and the rotation of the adjustment motor 702 can drive the high-pressure flushing gun 9 to swing up and down in the height direction of the hydraulic support, thereby realizing the longitudinal cleaning of the hydraulic support, and the rotation of the stepper motor 401 can drive the high-pressure flushing gun 9 to rise and fall in the height direction of the hydraulic support, thereby realizing the longitudinal cleaning of the entire surface of the hydraulic support, thereby making the cleaning more comprehensive.
