Movable clamping seat for connecting U-shaped steel bracket with individual hydraulic prop

Abstract

The invention relates to a movable clamping seat for connecting a U-shaped steel bracket with an individual hydraulic prop, and effectively solves the problems of poor effect, liability to sliding, potential safety hazards, large workload, high cost and resource waste in the connection between the individual hydraulic prop and the U-shaped steel bracket. To solve the problems, the invention adopts the technical scheme that the movable clamping seat comprises a clamping seat body, a masking sheet and a base, wherein the clamping seat body comprises a straight body and a U-shaped groove at the upper part of the clamping seat body; circular through holes communicated with each other are formed on two side walls of the straight body; the straight body is connected with the base below through the circular through holes; and the U-shaped groove and the masking sheet above are fixed together. The movable clamping seat provided by the invention has the advantages that the use is convenient; the mounting is easy; the connecting effect is good; the less laneway space is occupied; other unnecessary materials can be replaced and saved; great convenience is brought for underground safety and production; and the supporting is guaranteed to be stable and effective.

Description

technical field [0001] The invention relates to a movable clamp for connecting a U-shaped steel bracket and a single hydraulic prop. Background technique [0002] In the process of mine mining, most of the roadways using U-shaped steel supports are semi-circular arches or three-core arches, with an arch radius of 2~3m. The radius of U-shaped steel supports is affected by the geological structure or mining action during the support process. The support is affected by the sudden increase and concentrated mine pressure of the surrounding rock formations in the roadway. In this case, the support part will be crushed, the roadway will be deformed, and even personal casualties will be caused. Secondly, at present, many coal mines use a single hydraulic prop as a reinforced support, but the joint between the single hydraulic prop and the U-shaped steel bracket is connected longitudinally by multiple long beams of a single column, and fixed with iron chains and steel bars, so that t...
