Description

Technical Field

[0001] The utility model relates to the technical field of maintenance brackets, and in particular to a maintenance bracket used for dismantling an original bracket in a triangular area. Background Art

[0002] The maintenance support of the original frame removed from the triangle area is an important process in coal mining and working face production. During the withdrawal of the comprehensive mining working face, in order to avoid difficulties in the withdrawal of the support and to form a working area for personnel, it is necessary to create a "triangle area", that is, to provide support and protection in the area close to the support withdrawal and where the roof has not collapsed. This not only reduces the pressure on the roof and is conducive to the withdrawal of the support, but also allows the roof to be maintained and facilitates roof management. Therefore, the maintenance support plays a vital role in the process of dismantling the original frame in the triangle area.

[0003] After searching, the Chinese patent publication number CN209959267U disclosed "a new type of detachable comprehensive mining working face roof support device, including one to seven row structures, the row structure includes four columns, and the top outer walls of the four columns are fixed with the same roof beam by bolts, the outer walls of one side of the four columns are fixed with the same connecting plate by bolts, and the bottoms of the four columns are all sleeved with fixed column sockets, the bottom outer walls of the four fixed column sockets are fixed with column boots by bolts, the bottom outer walls on both sides of the row structure are connected with the same moving mechanism, and the moving mechanism includes two self-moving cylinders, the outer walls of the opposite sides of the two self-moving cylinders are fixed with the same column boot connecting pin by bolts, the top outer wall of the roof beam is provided with a supporting plate, and the outer wall of one side of the supporting plate is hinged with a side plate beam near one end."

[0004] However, in the process of implementing relevant technologies, the above-mentioned device has technical defects. Among them, the patent installs multiple rows of columns for support after the comprehensive mining working face is withdrawn to the protective support. As the support is continuously withdrawn and the triangle area is continuously enlarged, it is gradually installed to seven rows and the columns are increased or decreased at any time according to the site conditions. However, this support method requires a large increase or decrease in the number of columns, and the installation and disassembly of the columns need to be completed entirely by manual labor, which greatly increases the labor efficiency of the workers. In addition, the installation and disassembly process is time-consuming, which also reduces the efficiency of dismantling the original frame. In view of this, the utility model proposes a maintenance bracket for dismantling the original frame in the triangle area. Utility Model Content
