Anchor cable protection device

Abstract

The invention relates to the technical field of anchor cable protection, in particular to an anchor cable protection device which comprises a sleeve, a first limiting block, a fixing assembly and a reinforcing assembly, the first limiting block is fixedly connected with the sleeve, the reinforcing assembly is arranged on the sleeve, and the fixing assembly comprises a pull rod, a clamping block, a pulling block and a spring. The clamping blocks are installed at the ends, located in the sleeve, of the pull rods, the pulling blocks are installed at the ends, away from the clamping blocks, of the pull rods, the springs are arranged on the outer sides of the pull rods in a sleeving mode and located between the clamping blocks and the sleeve, the anchor cable is fixed through the two clamping blocks, and the sleeve is fixed to the anchor cable; the pull rod and the first limiting block are matched to play a limiting role, and the sleeve is prevented from being separated from the eye hole of the T-shaped steel, so that the sleeve continuously sleeves the eye hole of the anchor cable and the T-shaped steel to protect the anchor cable, and the anchor cable is prevented from being separated when the T-shaped steel moves.

Description

technical field [0001] The invention relates to the technical field of anchor cable protection, in particular to an anchor cable protection device. Background technique [0002] In the process of coal mining, in view of the development of geological structures, unstable coal measure strata, and large changes in roadway engineering geological conditions, the application of anchor cable support technology has increased, but the anchor cable has many fractures during use, and the large Most of the fracture surfaces are flat cut surfaces, which may be caused by the displacement of the top plate of the anchor cable during use, which causes the T-shaped steel to move at the same time, and the hole of the T-shaped steel will cut the anchor cable, causing the anchor cable to break. [0003] In the prior art, by putting an outer jacket on the anchor cable, the position of the anchor cable will also change when the top plate and the T-shaped steel belt are displaced, and during the di...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of anchor cable protection device, aims to solve the problem in the prior art by putting a jacket on the anchor cable jacket, but the position of the anchor cable will also change when the top plate and the T-shaped steel strip are displaced, and the anchor cable In the process of displacement, the protective cover is easy to fall off from the eye hole, which cannot continue to protect the anchor cable, and the effect of continuous protection on the anchor cable is poor.
