A flexible support device for steeply inclined coal seam

Abstract

The invention discloses a flexible support device for steeply inclined coal seams, which belongs to the technical field of coal mine support machinery. It includes a left support plate, a left top plate, a right top plate, a right support plate, a left hydraulic cylinder, an upper hydraulic cylinder and a right hydraulic cylinder. The left support plate is hinged to the left top plate, the left top plate is hinged to the right top plate, the right top plate is hinged to the right support plate, the left support plate is hinged to one end of the left hydraulic cylinder, the other end of the left hydraulic cylinder is hinged to the left top plate, and one end of the upper hydraulic cylinder It is hinged with the left top plate, the other end of the upper hydraulic cylinder is hinged with the right top plate, one end of the right hydraulic cylinder is hinged with the right top plate, and the other end of the right hydraulic cylinder is hinged with the right support plate. The invention provides a flexible support device for steeply inclined coal seams on the basis of ensuring stable supporting force, easy operation, and the supported mineway is not prone to roof leakage and is easy to carry, so as to provide more efficient support for coal mining under the condition of steeply inclined coal seams. Safe and reliable support cover.

Description

technical field [0001] The invention belongs to the technical field of coal mine support machinery, in particular to a flexible support device for steeply inclined coal seams. technical background [0002] Coal mine support equipment is an important guarantee for coal miners to safely mine coal, especially in steeply inclined coal seam conditions, where the pressure from the roof (coal seam) is relatively high, and safety accidents caused by poor support performance occur from time to time. [0003] At present, the "flexible support coal mining method" is widely used in the mining of steeply inclined coal seams. This type of support structure is to process the I-beam into a polygon, and then connect the I-beam top beams together with steel wire ropes to form a conjoined support for the entire working face. This kind of support can basically provide support for mining in steeply inclined coal seams by adopting a pseudo-incline arrangement, and has good economic and social be...

Problems solved by technology

[0004] Although this kind of support solves the support problem of the working face to a certain extent, so that the working face has a safer production environment, but this kind of support also has its obvious disadvantages

First, because the bracket arms of this kind of support are relatively thin, it is easy to leak the roof between the brackets and hurt people; second, because the working angle of the bracket of this kind of support is not adjustable, it has poor adaptability to the roof coal seam; Third, it has no hydraulic operation and control system and cannot be folded. It needs frequent disassembly and assembly and is not easy to carry, resulting in high labor intensity for workers; in addition, the steel wire rope is easy to wrinkle, deform and even break
