Description

Hydraulic support suitable for uneven ground Technical Field The invention relates to the technical field of roadway support, in particular to a hydraulic support suitable for uneven ground. Background The roadway hydraulic support device is key equipment for guaranteeing the safety of underground coal mining operation, is mainly used for supporting a working face top plate and providing stable operation space for coal mining and transportation, and in the coal mining process, geological conditions are complex and changeable, and the working face ground is often uneven, gradient change, height fall and the like due to mining influence, geological structure movement or historical collapse. At present, when the existing roadway hydraulic support device is applied to uneven ground, the terrain adaptability of the existing roadway hydraulic support device is poor, the traditional hydraulic support base is generally of a rigid structure or only has simple plane leveling capability, when the ground slope is large or the ground slope is partially concave and protruding, the support cannot effectively fit with the ground, the support body is inclined and stressed unevenly, side turning or tilting can occur in severe cases, and the stability and safety of support are greatly affected. Disclosure of Invention Aiming at the defects in the prior art, the invention provides the hydraulic support suitable for uneven ground, and solves the problem of poor stability and safety of roadway support when the ground is uneven.
