Abstract

An anchor net hooking wrench is optionally configured with a common quick-release ratchet wrench on the market as a force arm, and the optional configuration and the assembly and disassembly of the anchor net hooking wrench are convenient. The invention well solves the problems as follows: heading face bolts need to be dismounted from anchor net stubbles between cycles, resulting in secondary looseness of a heading face roof; metal net is connected through iron wires, so that manpower and material resources are wasted, the support cost is increased, and the labor efficiency is reduced; and during lapping of anchor net pieces, in order make lapping easy, workers often reduce iron wires used in lapping or lapping points, resulting in great potential safety hazards. The anchor net hooking wrench greatly increases the production efficiency, saves the engineering cost, and is applicable to engineering environments, in which anchor net pieces for supporting are needed, such as underground coal mines, subway tunnels and foundation pit supports.

Description

Technical field:

[0001] The invention relates to an anchor mesh hooking wrench, which is suitable for underground mines, subways and other engineering environments where anchor mesh sheets are required for support. It is convenient and fast to hook and connect the anchor net, the network effect is good, and the mesh is not easy to blow the net; the stubble of the anchor net does not need to be unloaded between the loops to prevent the second loosening of the roof; the use of network wire is reduced, and the work is improved. efficiency. Background technique:

[0002] With the development of support technology, anchor net support should be more and more widely used, but the problem of mesh overlapping and stubble pressing has not been solved. The main problems are as follows: (1) The anchor net stubble needs to be unloaded between cycles Head-on bolts cause secondary loosening of the head-on top plate. (2) Iron wire is used for metal mesh networking, which wastes manpower a...
