Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic support maintenance, in particular to a maintenance device for a coal seam hydraulic support. Background Art

[0002] Hydraulic support is a structure used to control the mine pressure of coal mining working face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. In the mechanical system of interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of each support member of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly in the same straight line, then the hydraulic support is very suitable for the surrounding rock of the mining face.

[0003] The Chinese utility model patent application publication specification CN205117384U discloses a maintenance device for the top beam of a large mining height hydraulic support, including a lifting jack, a maintenance platform, a driving rod, a guide connecting rod and a driving jack. The lifting jack is hinged to the top beam of the hydraulic support and the maintenance platform respectively. One end of the driving rod is hinged to the lifting jack, and the other end is connected to the guide rod and the driving jack. The driving jack and the guide connecting rod are hinged to the top beam of the hydraulic support respectively. The utility model solves the current situation that the underground top beam valve group of the large mining height hydraulic support is difficult to maintain, and combines the double telescopic jack with the maintenance platform and the top beam of the hydraulic support into a parallel four-bar linkage mechanism to realize the two-dimensional rotation and lifting action of the maintenance platform, which can effectively save underground space and avoid obstructing the passage of the coal mining machine. At the same time, the single telescopic drive jack is embedded in the locking mechanism and combined with the parallel four-bar linkage to complete the two-dimensional translation drive and locking of the maintenance platform, which improves safety. However, the structure of the device is slightly complicated, and its mobility is weak and its flexibility is insufficient. For this reason, we proposed a maintenance device for coal seam hydraulic supports. Utility Model Content
