Description

Technical Field

[0001] The utility model belongs to the technical field of coal tunnel support, in particular to an anchor net support positioning structure. Background Art

[0002] Anchor mesh support is a form of support consisting of wire mesh, steel mesh or plastic mesh fixed or tied to anchor rods with a support plate. Its main functions include suspension and composite beam functions, which are used to maintain the surrounding rock between the anchor rods and prevent small pieces of loose rock from falling. It is used to ease and reduce the movement of the surrounding rock so that the cross-section of the tunnel will not be excessively reduced, and at the same time prevent the scattered and damaged surrounding rock from falling.

[0003] The utility model patent with patent application publication number 202322501421.X discloses a tunnel wall anchor net support structure, including a hydraulic rod, a limiting mechanism, a fixing mechanism, a lifting mechanism and an anchoring mechanism; the limiting mechanism is arranged on the outer wall of the hydraulic rod for auxiliary fixation; the fixing mechanism is arranged at one end of the limiting mechanism to improve the installation stability, and the fixing mechanism includes a positioning cylinder for auxiliary fixation, fins for limiting and a detachable replacement head; the lifting mechanism is arranged at the top of the hydraulic rod to improve the support stability, and the lifting mechanism includes a support block for supporting a beam and a support plate, and the bottom of the support block is fixedly connected to the top of the hydraulic rod. Through the coordinated arrangement of the limiting mechanism and the fixing mechanism, the support stability of the hydraulic rod can be guaranteed during the support process, and the fixing mechanism can increase the connection stability with the tunnel wall, thereby further ensuring the overall support effect of the device.

[0004] According to the above patent, there is an anchor net support positioning structure, which still has shortcomings in actual use. The most obvious one is that the current anchor net is usually fixed to the mounting frame by bolt fasteners. When the anchor net support is found to be damaged or failed, it needs to be removed and replaced in time. However, since the anchor net is fixed by multiple sets of bolts, the staff needs to use professional disassembly tools to carefully disassemble the bolts one by one. The operation is complicated, which is not convenient for disassembly and assembly of the anchor net and increases the labor intensity of the staff. For this reason, we propose an anchor net support positioning structure. Utility Model Content
