AI Technical Summary
In existing technologies, during the support process of hydraulic supports at the end of fully mechanized mining faces, the top beams are prone to repeated compression of the roadway roof, leading to damage to anchor bolts and cables. The adjustment range is small and the roof contact area is insufficient, posing a risk of roof collapse in the remaining roadway section.
A lateral self-moving hydraulic support for the end of an anchor bolt and cable was designed. It adopts an avoidance link, an avoidance boss, a baffle and a track structure. The avoidance boss is driven to slide laterally by a telescopic beam jack. With the help of the track guide, it can achieve a large range of avoidance, avoid the phenomenon of top collision and enhance the stability of the support.
It achieves a wide range of avoidance, with the avoidance boss in close contact with the roof, enhancing support stability, reducing failure rate and maintenance costs, facilitating its application in existing end hydraulic supports, adapting to non-linearly distributed anchor bolts and cables, and improving the safety and economy of roadway retention along the goaf.
