Description

Technical Field

[0001] The utility model relates to the technical field of top plate supports, in particular to a top plate support structure. Background Art

[0002] In the current coal industry, large mining height (referring to the larger distance between the roof and floor of the mining face) has become a trend. However, large mining height coal mining faces a serious problem, namely the control of broken roof. The roof refers to the coal seam or rock layer above the mine working face. Its stability is crucial to coal mine production and miners' safety. As the mining height increases, the thickness of the roof decreases, and the mechanical properties deteriorate, making the roof easier to break, which leads to an increased risk of roof collapse and fracture. Statistics show that accidents caused by instability of broken roofs at large mining heights account for a large proportion of coal mine accidents, seriously threatening the lives of miners and the safe production of coal mines.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN211369647U discloses a new type of top plate support structure. The utility model includes a support rod, a base, and a rotating shaft, a motor, a thrust bearing, a pressure sensor, a worm and a turbine installed in the base; the rotating shaft is fixedly connected to the turbine and rotatably connected to the base, the worm is rotatably connected to the base and meshes with the turbine; the rotating shaft is vertically upward and rotatably connected to the lower end of the support rod through a thread, the motor is fixed in the base and the output shaft of the motor is fixedly connected to the worm, and the motor drives the worm to rotate and thus the support rod is raised and lowered; the lower end of the rotating shaft is rotatably installed in the base through a thrust bearing and the pressure sensor is located between the thrust bearing and the base. The utility model puts the support rod in a top-tight state, the top plate template is balanced in force, and the construction quality is improved.

[0004] The existing roof support structure has certain limitations in its force range. When supporting a large mining height roof, the support structure is prone to insufficient support force, which affects its use in the coal industry. At the same time, the roof structure and the coal mine rock have a single connection, which causes the roof to shake during use, reducing the practicality of the roof structure and causing the risk of roof collapse and breakage.
