Problems solved by technology

[0003] Most of the existing U-shaped steel brackets are a U-shaped steel frame structure. When the wall at the top of the roadway appears and changes and falls, its force directly acts on the U-shaped steel bracket, causing it to deform or even damage, causing the support to be unstable and reducing its service life

Abstract

The invention relates to the field of brackets, in particular to a compressible U-shaped steel bracket. The compressible U-shaped steel bracket comprises a support rod, a support mechanism, a fixing mechanism, a connecting mechanism, a strengthening mechanism, a lighting mechanism and a warning mechanism, wherein the support mechanism is fixedly connected to the upper end of the support rod, the support mechanism comprises a mounting block, U-shaped frames, slots, a compressible spring, a strip-shaped opening, a limiting screw and a threaded groove, the mounting block is fixedly connected to the upper end of the support rod, the slots are formed in the side wall of the upper side of the mounting block, the two U-shaped frames are inverted and are inserted into two groups of slots, the compressible spring is connected to the inner wall of the lower side of the slots, the U-shaped frames are abutted with the compressible spring, the strip-shaped opening is formed in the side wall of themounting block and communicates with the slots, and one end of the limiting screw penetrates through the strip-shaped opening in a transverse direction. The compressible U-shaped steel bracket provided by the invention has the advantage of long service life, the support safety of a tunnel is increased, and the personal safety of working personnel is guaranteed.

Description

technical field [0001] The invention relates to the field of brackets, in particular to a U-shaped steel bracket that can be pressed. Background technique [0002] The roadway is a passage dug for mining lifting, transportation, ventilation, drainage, power supply, etc. during underground mining. The section shape of the roadway is mostly arched, trapezoidal or rectangular, and the surrounding rock is soft and round, oval or horseshoe-shaped. Generally, the roadway is supported by U-shaped steel brackets to prevent the roadway from collapsing and ensure the personal safety of the staff. [0003] Most of the existing U-shaped steel brackets are a U-shaped steel frame structure. When the wall at the top of the roadway appears and changes and falls, its force directly acts on the U-shaped steel bracket, causing it to deform or even damage, causing the support to be unstable and reducing its service life. Therefore, it is necessary to provide a new compressible U-shaped steel...
