[0001] The invention relates to the technical field of coal mine fully mechanized mining, in particular to a large mining height hydraulic support maintenance device for a coal mining working face. Background Art

[0002] At present, more and more coal mine working faces use large mining height hydraulic supports. Due to the high working height of the supports (especially when the support height is above 6 meters), it is very difficult to inspect and repair various accessories on the top beam and the cover beam, such as joints, hoses, valves, etc. Usually, the inspection and maintenance of large mining height hydraulic supports on domestic fully mechanized working faces is mainly carried out by manually carrying high ladders, which are placed obliquely on the supports. After climbing to a certain height, the maintenance personnel stand or sit on the edge of the ladder for inspection and maintenance.

[0003] However, the above method has the following defects: ① The ladder height is limited, and there is a certain blind spot when inspecting the top of the top beam, and the entire top area of ​​the bracket cannot be covered; ② Repeatedly moving the ladder on the work surface and going up and down the ladder back and forth causes the workers to work on the edge of the ladder, which is labor-intensive and dangerous. Summary of the invention

[0004] The purpose of the present invention is to provide a high-mining hydraulic support maintenance device for a coal mining face, which is designed to solve the problem that workers need to use a ladder to go up and down the high ladder, and avoid the height limitation of the ladder, which makes it impossible for workers to repair the support.
