U-shaped steel support double-groove clamping plate anti-skid anti-snap safety clamp set and installation method

Abstract

The invention discloses a U-shaped steel support double-groove clamping plate anti-skid anti-snap safety clamp set and an installation method. The U-shaped steel support double-groove clamping plate anti-skid anti-snap safety clamp set comprises upper limiting clamps (1), middle limiting clamps (2) and lower limiting clamps (3), wherein the upper limiting clamps (1), the middle limiting clamps (2)and the lower limiting clamps (3) are installed on the upper portion, the middle portion and the lower portion of a lap joint portion of the U-shaped steel support. The U-shaped steel support double-groove clamping plate anti-skid anti-snap safety clamp set effectively solves the problems that due to insufficient work resistance, the support effect is poor and even lose efficacy, and a nut or ascrew snaps and hurts people; and besides, the manufacturing technology is simple, installation operation is easy, the connection requirement of the U-shaped steel support is met, and obvious engineering application benefits are achieved.

Description

technical field [0001] The invention belongs to coal mine roadway support technology, and in particular relates to a U-shaped steel shed double-groove plywood anti-slip and anti-breaking safety card cable set and an installation method. Background technique [0002] U-shaped steel shed support has the advantages of large pressure bearing capacity, long support time, easy installation, and not easy to deform. It is an effective way to solve the roadway support under complex and difficult conditions in coal mines. As the core component of the U-shaped steel shed support, the reliability of the cable connecting the U-shaped steel lap length (generally about 400mm) is the key to the effective support of the U-shaped steel shed, so it must meet the requirements of durability, safety and stability. At present, due to various defects in the design and processing of conventional cables, when U-shaped steel sheds are used for support under complex and difficult conditions, staggered ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the invention: to provide a U-shaped steel shed double-groove plywood anti-skid and anti-break safety card cable set and installation method to solve the problem of U-shaped steel support when the roadway is supported by U-shaped steel shed under complex and difficult conditions in coal mines. The connection parts are prone to misalignment and slippage and nut or screw breakage, which will cause technical problems with serious consequences such as large deformation of the roadway, nut or screw breakage and injury due to insufficient support resistance or even failure.
