目前,国内外凿岩钻车推进器的主要推进方式有:1.液压缸(或气缸)—钢丝绳推进;2.液压马达(或气马达)—减速器—链条推进;3.液压马达(或气马达)—螺杆推进。推进器的作用是①保证凿岩机和钎杆在凿岩过程中的顺利推进和退出,②保证每次所凿炮孔深度一致。推进器的导轨有两组轨道:一组上轨道,供滑座在上面移动,滑座上安装凿岩机,在推进油缸—钢丝绳的作用下,滑座带着凿岩机沿着轨道送进和退出;另一组是下轨道,把它安装在托架的导槽内,在旁侧补 At present, the main propulsion methods of rock drilling drills at home and abroad are as follows: 1. hydraulic cylinder (or cylinder) - steel wire rope propulsion; 2. hydraulic motor (or air motor) - reducer - chain propulsion; 3. hydraulic motor Gas motor) - Screw advance. The role of propeller is to ensure that the rock drill rig and drill rod in the process of smooth advance and exit, to ensure that each time the depth of the chisel hole consistent. The track of the thruster has two sets of tracks: a set of tracks on the track for the carriage to move on, and a rock drill mounted on the carriage. Under the action of the propulsion cylinder-wire rope, the carriage carries and withdraws along the track with a rock drill; The group is under the track, install it in the guide groove of the bracket, make up on the side
