Description

Recursion slideway type advanced hydraulic support without repeated supporting effect

Technical Field

The utility model relates to the field of mechanical equipment, specifically a do not have recurrence slide formula hydraulic support in advance who supports the effect.

Background

With the continuous development of artificial intelligence technology, the research work of combining intellectualization and specific industries is actively promoted in various fields of social industry in China. At present, an intelligent mine is built as a research hotspot problem of coal mining, and more than 100 intelligent mines in China are built. Meanwhile, the coal mine in China mainly has two forms of an advance hydraulic support and a single prop intensive support in the aspect of roadway advance support equipment of a stope face, and the single prop support needs to consume a large amount of human resources, so that the labor intensity is high, the safety is poor, and the fault phenomenon occurs in the transportation of the coal mine exhibition industry at present, so that the single prop support is gradually replaced by the advance hydraulic support. Compared with a supporting mode of a single hinged top beam, a common advance hydraulic support is greatly improved, but the problem that the top surface of a coal mine is loosened in the middle east region is solved, the common advance hydraulic support integrally moves forwards in groups, the frame moving mode is that the advance support in the whole advance supporting region moves by one step distance, all the advance supports need to complete a frame descending, frame moving and frame lifting action cycle, the top beam is unloaded when contacting the frame descending region, and the frame is loaded when being lifted, so that the structure of the top surface of the coal mine can be loosened due to high-frequency repeated supporting, the original top plate support which is complete in structure and stable in supporting system is broken, the structural integrity of a roadway top plate is seriously damaged, and a supporting system formed by anchor cables is adopted. When the roadway roof and the anchor net cable supporting pressure arch are damaged, accidents such as roof leakage, roof fall, large deformation of a crossheading section and the like can occur, meanwhile, the dead weight of the broken roof acts on the forepart support, and the movement of the forepart support can be influenced in serious cases. Based on the problems of the advance section of the coal face of the existing underground coal mine, a recursion slideway advance hydraulic support which is suitable for the condition that the top plate is unstable and has no repeated supporting effect on the top plate is designed. The method comprises the step of designing a recursion slide type advanced hydraulic support structure, realizing that a support at the advanced section of a working face moves by taking the cut depth of a coal mining machine as a step pitch, and simultaneously realizing synchronous propulsion by matching with equipment in crossheading at two sides. The problem of the roof structure of the middle east area colliery pine and collapse, colliery stope face super anterior segment's support problem and along with loaded down with trivial details, the complicated removal of inslot equipment is effectively solved.
