Problems solved by technology

Since the top beam of the hydraulic support is rigid, the unevenness of the direct roof will cause uneven loads between the two, which can easily cause local roof fall accidents, and even cause safety hazards in coal mines.

Abstract

The invention relates to an exploitation tunneling shield support for a mine. In the coal exploitation process, in order to prevent roof falling accidents, a hydraulic support needs to be used for timbering a top plate. As a top beam of the hydraulic support is rigid, and uneven loads between the top beam and the top plate will be caused by unevenness generated by directly supporting the plate, the local roof falling accidents will be easily caused, and even the safety hidden dangers of causing large mine roof falling accidents exist. The exploitation tunneling shield support for the mine comprises a base, the top beam, a crawler device and a first hydraulic cylinder, a plurality of second hydraulic cylinders are arranged on the top beam, and the top plate is connected to the top ends of the second hydraulic cylinders. The exploitation tunneling shield support has the advantages of being simple in structure, safe and convenient to operate, good in timbering performance, easy to apply and popularize and the like; the roof falling accidents can be effectively prevented, and the coal exploitation operation safety is guaranteed.

Description

technical field [0001] The invention relates to a support, in particular to a coal mine excavation protection support. Background technique [0002] In the process of coal mining, in order to prevent roof fall accidents, it is necessary to use hydraulic supports to support the roof. Since the top beam of the hydraulic support is rigid, the unevenness of the direct roof will cause uneven loads between the two, so it is easy to cause local roof fall accidents, and even cause safety hazards in coal mines. Contents of the invention [0003] The object of the present invention is to provide a coal mine excavation and excavation shield bracket with simple structure, convenient operation and improved support state. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a coal mining excavation shield support, including a base, a top beam, a crawler belt device and a first hydraulic cylinder, and a plurality of seco...
