Problems solved by technology

In the roadway supported by bolt + anchor cable, the bolt only needs to control the deformation and displacement of the shallow surrounding rock, and the anchor cable needs to control the total deformation and displacement of the shallow and deep surrounding rock, so the anchor cable bears the tension of the surroundin

Abstract

The invention discloses a high-elongation dynamic coupling mine anchor cable device, which comprises an anchor cable steel strand, an anchor cable disc arranged sequentially on the anchor cable steel strand, an anchor ring connected with the anchor cable disc, and an anchor cable connected with the anchor cable. Ring-connected rigging clips; high elongation dynamic coupling mine anchor cable device, the anchor cable anchoring end core wire welding spot is arranged at the end of the anchor cable inner section; the end of the exposed end of the anchor cable is provided with an anchor The core wire welding spot at the exposed end of the anchor cable; the inner section of the anchor cable is provided with a core wire welding spot at the anchoring end of the anchor cable; the exposed end of the anchor cable is provided with a welding spot for the exposed end core wire of the anchor cable. The invention simplifies the installation process steps of the anchor cable, increases the range of deformation and displacement of the roadway carried by the anchor cable, improves the service life of the roadway, prolongs the repair period of the roadway, increases the effective use area of ​​the roadway, and contributes to the development of deep well support. Direction is guaranteed.

Description

technical field [0001] The invention relates to an anchoring device for a coal mine roadway, in particular to a high-elongation dynamic coupling mine anchoring device. Background technique [0002] Mine anchor cables have high load-bearing strength, wide range of surrounding rock control, convenient transportation and installation, and are widely used in mine support. The high load-bearing strength of the mine anchor cable means the high tensile strength of the anchor cable steel strand, and the high tensile strength and low elongation. Generally, the elongation of the mine anchor cable steel strand is 3.5 to 5.2%. The maximum extension length of the 8-meter anchor cable is only 0.28-0.42 meters, the elongation rate of the anchor rod is not less than 20%, and the extension length of the 2.6-meter anchor rod is not less than 0.52 meters; so the 8-meter-long anchor cable is not as long as 2.6 meters. The extended length of the anchor rod is large. In the roadway supported by...
