Title:
ANTI-IMPACT PROTECTION APPARATUS USING ANCHOR CABLES TO FORM MESH, AND USE METHOD
Document Type and Number:
WIPO Patent Application WO/2023/236307
Kind Code:
A1
Abstract:
The present invention relates to the technical field of mine devices, and provides an anti-impact protection apparatus using anchor cables to form a mesh, and a use method. According to the present invention, in view of the problems that ejected coal rock blocks are easily stuck on existing protection meshes and the existing protection meshes cannot cushion and intercept the ejected coal rock blocks, which may easily cause the coal rock blocks to rebound to injure operators, the anti-impact protection apparatus using the anchor cables to form the mesh is provided. The apparatus comprises fixing mechanisms, the fixing mechanisms are provided on a heading machine, interception mechanisms are mounted on the fixing mechanisms, and a resistance mechanism and a tightening mechanism are provided on each interception mechanism. The interception mechanisms of the present invention intercept the ejected coal rock blocks, and first steel wire ropes and second steel wire ropes cushion the ejected coal rock blocks, thereby reducing the impact force of the coal rock blocks; the resistance mechanisms realize slow reset of the first steel wire ropes and the second steel wire ropes, so as to prevent the intercepted coal rock blocks from being ejected due to the reset thereof; and the tightening mechanisms realize the interception and clasping of the coal rock blocks while preventing the coal rock blocks from being stuck in holes of the mesh.
