Problems solved by technology
[0002] At present, the tops of the widely used anchors are mostly blunt. When using them, first drill holes in the places that need anchoring or support, and then inject the anchors. When injecting blunt anchors, it is often caused by improper operation of workers The deviation of the injection angle will cause the wall of the bolt eye to rise, which will bring inconvenience to the injection work of the bolt. Re-injection often results in a long leakage, which cannot achieve the effect of anchoring or supporting

Embodiment Construction
[0009] The rod head is processed into a conical shape, and the top is polished into an arc shape. When in use, the anchor rod is injected into the anchor rod eye. The conical design of the rod head 1 has a guiding effect. Even if there is a deviation during operation, the rod head will not move the anchor The wall of the rod eye is raised, which can smoothly guide the rod body 2 to inject into the anchor rod eye. When the anchoring position is reached, the tray 3 is installed, and the fastening nut 4 is tightened to complete the anchoring operation.

The invention provides a tapering-shape round-tip anchor rod which effectively avoids the disadvantages of the original blunt anchor rod. The tapering-type round-tip anchor rod consists of a tight nut, a tray, a rod body and a rod head, wherein the rod head adopts tapering-type design, and a tapering tip presents a circular-arc shape. When the anchor rod is injected, a tapering-type wall serves a good guide effect, namely, even if any error occurs during the operation, the anchor rod can be injected smoothly as well, thus achieving good anchoring effect.
Description
technical field [0001] The invention belongs to the field of roadway anchoring and support, in particular to a conical round-tip anchor rod. Background technique [0002] At present, the tops of the widely used anchors are mostly blunt. When using them, first drill holes in the places that need anchoring or support, and then inject the anchors. When injecting blunt anchors, it is often caused by improper operation of workers The deviation of the injection angle will cause the eye wall of the bolt to rise, which will bring inconvenience to the injection work of the bolt. Re-injection often results in a long leakage, which cannot achieve the effect of anchoring or supporting. Contents of the invention [0003] The invention provides a conical round-point anchor rod, which effectively avoids the disadvantages of the blunt anchor rod in the past. [0004] The present invention is achieved in this way: the anchor rod is composed of a fastening nut, a tray, a rod body and a rod...
