The invention discloses an anchor rod, including a main rod and a top block. The main rod is provided with through holes, gating holes, through holes and external threads. The through holes are arranged in the middle of the main rod, the gating holes are arranged outside the main rod, and the gating holes are connected with the through holes. The through holes are arranged at the front end of the main rod in a cross shape, and the external screw is arranged at the front end of the main rod. The thread is arranged at the back end of the main rod, and the outer thread is successively sleeved with a slurry stopper, a pad and a nut from the inside to the outside. The top block is connected to the through groove through a rotating shaft, and the inner side of the back end of the top block is integrally formed and connected with a connecting rod. A drive screw is connected with the rotary shaft at the back end of the slider, and the drive screw is threaded through and connected to the front end of the through hole, and a middle groove is arranged at the back end of the drive screw. The invention can easily fix the bolt in the surrounding rock of the roadway, and improves the firmness between the bolt and the surrounding rock.
【技术实现步骤摘要】
一种锚杆
本专利技术涉及一种锚杆,属于锚杆
技术介绍
锚杆是煤矿巷道支护的最基本的组成部分,他将巷道的围岩加固在一起,使围岩自身支护自身;目前所使用的锚杆大多采用涨壳进行固定,导致锚杆与围岩之间存有较大的空隙。为解决上述问题,特提供一种新的技术方案。
技术实现思路
本专利技术的目的在于提供一种锚杆,以解决上述
