为了解决手持式气动帮锚杆钻机帮部扭矩不足的问题,因顶部锚杆机技术使用比较成熟,运用顶部锚杆机改制成手持式气动帮锚杆扭矩扳手,通过现场实际应用,可有效解决帮部锚杆扭矩不足问题,满足高预应力锚杆支护的要求,且使用方便,提高工作效率,是弥补手持式气动帮锚杆钻机帮部扭矩不足的有力帮部扭矩工具。
In order to solve the problem of insufficient torque of the hand-held air-assisted bolt drilling machine, the roof bolt technology is more mature and the top-bolt machine is used to transform into a hand-held air-assisted bolt torque wrench, which can be effectively solved through field practical application To help the Ministry of bolt torque shortage, to meet the requirements of high prestressed bolt support, and easy to use, improve work efficiency, is to make up for the hand-held pneumatic bolt to help the Department of Ministry of inadequate torque to help a powerful Ministry of the Ministry of torque tools.
