永荣矿务局永川煤矿自行研制成功新型锚杆安装机。过去使用的树脂锚杆安装机价格昂贵(购买一台锚杆安装机2万多元)、体积大、质量重(一台锚杆安装机重达50公斤)、操作不方便(安装不同角度的锚杆需两人调整角度并握住支撑脚),还经常损坏锚杆丝扣。该矿利用风钻动力部位与废旧的765型凿岩机缸体柄体相联结而构成锚杆安装机,其机身由凿岩机的气腿支撑。新型锚杆安装机的特点是造价低廉(一台锚杆安装机仅3000多元)、体积小、重量轻(仅20多公
Yongrong Mining Yongchuan Coal Mine successfully developed a new type of bolt installation machine. The resin bolt installation machine used in the past was expensive (purchased an anchor installation machine more than 20,000 yuan), large size, heavy weight (a bolt installation machine weighing 50 kg), the operation is not convenient (installation of different angles The anchor needs two people to adjust the angle and hold the support foot), often also damage the anchor thread. The mine uses the pneumatic part of the pneumatic drill to connect with the used 765 rock drill cylinder handle body to form a bolt installation machine, and the fuselage is supported by the air leg of a rock drill. The new type of bolt installation machine is characterized by low cost (a single bolt installation machine only 3000 yuan), small size, light weight (only more than 20 public
