Description

Technical Field

[0001] The utility model relates to the technical field of coal mine filling and roof connection, in particular to a supporting device for coal mine filling and roof connection. Background Art

[0002] The development of filling technology and technique in my country has gone through the process of dry filling of waste rock, hydraulic filling of graded tailings and crushed stone, concrete bonded filling, fine sand bonded filling with graded tailings and natural sand as filling materials, waste rock bonded filling, high-concentration full tailings bonded filling and paste pumping bonded filling. Filling mining is the most ideal technical way to mine coal under buildings. In recent years, with the continuous development of coal mine filling technology, the application of filling technology in coal mining has become more and more extensive.

[0003] The utility model patent application document with publication number "CN216553978U" discloses an upper isolation plate of a hydraulic support for paste filling, which is mainly composed of a guard plate, a front beam, a top beam, a tail beam, an upper isolation plate and a lower isolation plate. This technical solution has the advantage of good sealing effect, and solves the shortcomings of the upper isolation plate of the existing hydraulic support in isolation sealing. Although the gap between adjacent hydraulic supports is isolated and compensated with the assistance of the upper side guard plate and the lower side guard plate, the upper side guard plate and the lower side guard plate cannot be directly overlapped due to design defects, so there is still a large gap between them, which is prone to leakage during the later paste filling.

[0004] The hydraulic support for paste filling disclosed in the above document has the following defects: during use, the hydraulic support for paste filling needs to be continuously moved according to work requirements, and the hydraulic support cannot be moved quickly. Since there is no transportation structure installed inside the hydraulic support, the process of moving the hydraulic support is relatively troublesome.

[0005] It can be seen from this that the existing hydraulic supports for paste filling do not have a structure that is convenient for transportation. It is necessary to improve the existing deficiencies and provide a supporting device for coal mine filling and top connection. Utility Model Content
