一、概述地下工程的锚杆支护作业,不仅艰苦,而且危险。特别是钻装向上的锚杆,劳动强度大,被称为淋头水的混有岩尘的浆液会顺人身自上而下,不易防护,而岩孔四周围岩松动落下,直接危及设备和人身安全。为改变这种艰苦而危险的作业,采用机械化钻装锚杆,把锚杆钻装的三个基本工序,即把凿孔、插杆、紧固或注浆的三步工序,由机械锚杆钻装车的转架一次连续顺序完成,而且操作人员可以远离工作面。为检验转架的设计质量、制造水平和在实际作业中的可靠性,对转架进行了试验室试验和工业试验。首先按设计要求,由扬州冶金机械厂制造出与在地下工程使用的转架尺寸相同的一台转架。继而在马鞍山矿山研 First, an overview of the underground works of bolt support operations, not only difficult, but dangerous. In particular, the uplift of rock bolts, labor-intensive, known as the head of water mixed with rock dust slurry will be top-down personal body, not easy to protect, but rock around the rock loose down, directly endanger the equipment and Personal safety. To change this difficult and dangerous operation, using mechanized drilling anchor, the three basic processes of drilling the anchor, that is, the three steps of drilling, inserting rod, fastening or grouting by mechanical bolt Drilling car turret completed a continuous sequence, and operators can stay away from the work surface. To test the design of the turret quality, manufacturing level and in the actual operation of the reliability of the turret laboratory and industrial tests conducted. First of all, according to the design requirements, Yangzhou Metallurgical Machinery Factory will manufacture a turret with the same size as the turret used in underground engineering. Then research in Ma’anshan mine
