Coal mine roadway temporary reinforcement supporting device in coal mine exploitation tunneling

Abstract

The invention discloses a coal mine roadway temporary reinforcement supporting device in coal mine exploitation tunneling. The coal mine roadway temporary reinforcement supporting device in coal mineexploitation tunneling comprises a coal mine roadway main body, a base, a mounting block, a connecting block and a pressure sensor. The base is arranged in the coal mine roadway main body. The mounting block is connected above the base. The connecting block is arranged above the mounting block. A connecting column is arranged above the connecting block. A bottom plate is inlaid at the upper end ofthe connecting column. A hydraulic rod is arranged on the upper surface of the bottom plate. A supporting plate is connected to the upper end of the hydraulic rod. A supporting column is inlaid on the upper surface of the supporting plate. The coal mine roadway temporary reinforcement supporting device in coal mine exploitation tunneling is provided with a limiting rod and a connecting groove, anoperating plate can be fixed through the cooperation of the limiting rod and the connecting groove, the stretching amount of a moving plate can be subsequently kept fixed, and meanwhile, connection with the connecting groove can be released through rotating of the limiting rod, so that a moving shaft can be controlled through the operating plate.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a temporary reinforcement and support device for coal mine roadway during coal mine mining and driving. Background technique [0002] As an important energy material, coal mines are widely used in industrial production and other fields. Since coal mines are generally hidden underground, the mining operations of coal mines are also underground operations. When mining coal mines underground, materials are generally collected by means of coal mine roadways. The stability of the coal mine roadway is related to the safety of mining for transportation and personnel entry and exit. After the roadway is excavated, it needs to be reinforced by the enclosure structure to ensure the stability of the roadway. Before the construction of the support structure, it can be temporarily supported. The device improves the support for the roadway, and it can be removed after the subsequent s...

Problems solved by technology

[0006] The purpose of the present invention is to provide a coal mine roadway temporary reinforcement and support device in coal mine excavation, to solve the problem of the existing coal mine roadway temporary reinforcement and support device in the market when supporting the top of the roadway proposed by the above-mentioned background technology The top of the roadway is mostly arched or other irregular shapes, and the fit between the top surface of the device and the inner wall of the roadway is low during support, which may easily lead to excessive local support force, resulting in deformation of the top of the roadway or the position of the top part cannot be effectively supported , and some coal mine roadway temporary reinforcement support devices lack their own positioning function during installation, and they are generally placed in the center by observation when performing support, and the problem of large position deviation
