Description

Technical Field

[0001] The utility model relates to the technical field of mine anchor rods, in particular to a mine mechanical anchor rod. Background Art

[0002] Mining machine anchor bolts are a type of geological support equipment used in underground mining and tunneling projects. Their function is to secure and reinforce rock masses, preventing rockfalls, landslides, or collapses, thereby ensuring the safety and stability of working surfaces and passageways. The installation of mining machine anchor bolts typically requires specialized techniques and equipment, including drilling machines and bolting machines. During use, rock mass exploration and analysis are first required to determine the anchor bolt's installation location and length. Drilling, grouting, or bolt insertion are then performed, followed by anchoring and securing. The appropriate anchor bolt type and specifications must be selected based on the geological conditions and project requirements.

[0003] After searching, the Chinese patent publication number CN 219826887 U discloses "a mine fault support anchor rod, including a hollow anchor rod, wherein the hollow anchor rod is provided with a fixing assembly; the utility model drives the rotating rod to rotate by rotating the concave hexagonal block to wind the wire rope, thereby causing the wire rope to pull the hemispherical block to slide into the truncated cone groove, so that the truncated cone groove is stretched and then fits with the wall surface of the anchor hole to achieve preliminary fixation, and then the rectangular fixing plate of the hollow anchor rod is fixed to the outer end wall surface of the anchor hole by rotating the hexagonal nut, without the need for temporary fixation, and after the hollow anchor rod is fixed, the circular pipe valve is opened to inject grouting liquid, and the circular pipe valve is closed after filling, and the heating wire is energized to accelerate the solidification of the grouting liquid and shorten the construction time."

[0004] After the above patent fixes the hollow anchor rod through the fixing assembly, the circular tube valve is opened to inject grouting liquid. After the grouting is full, the circular tube valve is closed and the heating wire is energized to accelerate the solidification of the grouting liquid and shorten the construction time. However, due to the lack of a protective structure for the anchor rod in the above patent, when the anchor rod is subjected to a strong extrusion force in the rock wall, it may break or be damaged, which will cause the anchor rod to be unable to reinforce the rock mass. In addition, the fixing plate used in the above patent is rectangular in shape, so when fixing an irregular rock wall, the fixing plate cannot fully fit with the rock wall, which will further cause the fixing effect of the fixing plate to deteriorate and the anchor rod may fall off the rock wall.
