Description

Technical Field

[0001] The utility model relates to the field of anchor bolts, in particular to a rapid installation device for a rock self-locking anchor bolt. Background Technique

[0002] The anchor bolt is used to reinforce the surrounding rock of the roadway so that the surrounding rock supports itself. Now, the anchor bolt is not only used in mines but also in engineering technology to reinforce the main bodies of slopes, tunnels, and dams. As one of the main support forms for underground projects and rock slopes, the anchor bolt plays an important role in maintaining the stability of civil engineering.

[0003] The reinforcing effect of the anchor bolt on the rock is very obvious. However, when the current anchor bolt is used to reinforce the rock, it is necessary to drill holes in the rock first and then install the anchor bolt for reinforcement. The installation of the anchor bolt in this way is rather troublesome, which reduces the installation speed of the anchor bolt. Therefore, we propose a rapid installation device for a rock self-locking anchor bolt to solve the above problems. Content of the Utility Model
