一种本安型压裂管推送装置及其使用方法
摘要：
本发明属于煤矿井下瓦斯抽采技术领域，涉及一种本质安全型的压裂管推送装置。它由支座1、立柱2、悬挂装置3、推送装置4、顶杆5等组成。利用本装置，可以把压裂管送入更深的孔中，提高效率，降低劳动强度，提高压裂技术的应用。支座1放置在底面，立柱2竖直插在支座1上的孔中，悬挂装置3可沿立柱2上下滑动，以适应不同高度的压裂钻孔。悬挂装置3与推送装置4联结成一体，推送装置4利用井下的压缩空气为动力，驱动丝杠旋转，带动安装在推拉座上的压裂管移动。顶杆5的内杆可在外管内部滑移并固定，丝杠固定在内杆上，转动丝杠，可调整顶杆的长度，并使顶杆以一定的压力固定推送装置。
摘要（英）：

The invention belongs to the technical field of gas extraction of underground coal mines and relates to an intrinsic safety type fracture tube push device. The device is composed of a supporting base 1, a stand column 2, a hanging device 3, a push device body 4, an ejector rod 5 and the like. Through the device, a fracture tube can be fed into a deeper hole, efficiency is improved, labor intensity is reduced, and the application range of the fracture technology is widened. The supporting base 1 is placed on the ground, the stand column 2 is vertically inserted in a hole in the supporting base 1, and the hanging device 3 can vertically slide along the stand column 2 so as to adapt to fracture drilling at different heights. The hanging device 3 and the push device body 4 are connected into a whole, and the push device body 4 uses underground compressed air as power to drive a lead screw to rotate so that the fracture tube installed on a push and pull base can be driven to move. An inner rod of the ejector rod 5 can slide in an outer tube and be fixed, the lead screw is fixed to the inner rod, the length of the ejector rod can be adjusted by rotating the lead screw, and the ejector rod is made to fix the push device with certain pressure.
