The utility model relates to a percussion drill repair auxiliary device, which belongs to the construction auxiliary equipment of the anti-seepage wall project, and in particular relates to an auxiliary device for repairing drilling tools. It consists of a base and an upper bracket, the base and the upper bracket are a rectangular frame composed of long and short rods. The four corners of the base and the upper bracket are connected through a connecting rod. The connecting rod is extended upward to form an extension section, and a parallel supporting shaft is set at the top of the extension section. The supporting shaft is fitted with a guide wheel and the whole device is set. It is a four prism structure. The beneficial effect of the utility model is that the drilling tool pad is removed from the ground by the four prism structure with a certain height, and the two groups of guide wheels on the top of the four prism structure are in contact with the round embryo of the drilling tool, which can reduce the effect of the friction of the drilling tool, save the artificial body force, speed up the maintenance progress, and ensure the seepage prevention. The normal construction will create favorable conditions to improve the efficiency of the cut-off wall.

一种冲击钻具修护辅助装置
本技术属于水利水电工程建设
,尤其是防渗墙工程施工辅助设施,具体涉及一种钻具修护辅助装置。
技术介绍
在水利水电工程中,作为基础防渗处理方式的防渗墙得到了广泛应用,在防渗墙施工中常常会遇到随机分布的的孤漂石,由于形状大小各异、厚度不一,孔内状况复杂,穿透孤漂石成孔难度大,在这类地层中钻孔成槽钻进效率低、钻具寿命短,尤其是在强度较高的花岗岩性地层中进行防渗墙成槽施工,钻具磨损快,维修频率高。因防渗墙成槽施工采用的“十”字钻具,“空心”管状钻具长度为2~5m,重量在3~6t之间,在施工中发现钻具磨损后常规的做法是采用装载机或吊车将钻具转移至空旷地面进行维修。因钻具结构组成为在固定大小圆形胚体上加焊不规则的翼角以满足墙厚要求,因此在地面对钻具进行翻转,存在钻具重量大、与地面的接触面广、摩擦力大等情况,在维修补焊过程中常采用千斤顶或人工撬动的方式对钻具进行翻转,以达到对钻具进行360°维修的目的,该过程转动钻具速度慢,人工劳动强度较高,尤其在高寒高海拔缺氧地区工效降低尤为明显。
