Description

Technical Field

[0001] The utility model relates to a shear-resistant anchor, in particular to a shear-resistant anchor for mining, belonging to the technical field of anchors. Background Art

[0002] Anchors refer to permanent anchoring devices used in prestressed concrete. They are anchoring tools used in post-tensioned structures or components to maintain the tension of prestressed tendons and transfer it to the interior of concrete. They are also called prestressed anchors. They are usually pre-installed and positioned, and then poured with concrete. They are buried at both ends of the concrete, that is, the two ends of the corrugated pipe. They are end faces set for the stabilizing effect of the jack during tensioning.

[0003] The patent application CN214884878U relates to the field of anchors, and in particular, to an anti-shear anchor, which includes an anchor ring, an anchor pad and a clip, wherein a boss is fixedly connected to the middle of the anchor pad, a steel strand is passed through the anchor pad and the boss, and an embedding groove for accommodating the boss is provided at one end of the anchor ring close to the anchor pad. The application has the effect of improving the radial shear force on the steel strand at the connection between the anchor pad and the anchor ring.

[0004] During mining and production in the mine, anchors are used to reinforce the equipment. When the equipment is running, vibration or movement will occur, and friction will occur between the steel strands and the clips. Long-term friction can easily cause damage to the steel strands, reduce the mechanical properties of the steel strands, and shorten the service life of the steel strands. For this reason, we provide a mining shear anchor to solve the above problems. Utility Model Content
