Long-distance injection pipe down pipe device

Abstract

The invention relates to a long-distanceinjectionpipedown pipe device.The device comprisesa high pressure drive pipe, acone shapeplug, a connection buckle, the cone shapeplugcomprises a broken barrier head, abearing frame, a hydraulic motor and a drive shaft, the broken barrier head is a hollow cone structure, a bearing cavity is arranged inside the broken barrier head, the drive shaft, thebearing frame and the hydraulic motor are all embedded inthe bearing cavity body, the frontend of the drive shaft and the inner surface of the broken barrier head are connected, the tail end is connectedwiththe hydraulic motor, the bearing frame comprises abearing disc and a connection spoke rod, the connection board through a positioning hole isconnected with thehigh pressure drive pipe, the high pressure drive pipe through a guide pipeis mutually connected with the hydraulic motor,and a number of connectionbuckles are evenly distributed on the high pressure drive water pipe along theaxial direction of the high-voltage drive pipe. The device on the one hand can effectively improve the breakthrough ability of the injection pipeto the obstacles in the drill holes when in the process of down drilling, the layout pipe and the work efficiency and the quality of the injection pipe positioning are improved, on the other hand the obstacles in the drill holes are cleaned up and broken,and the drill hole qualityis improved.

Description

technical field [0001] The invention relates to a long-distance grouting pipe lowering equipment, which belongs to the technical field of geological exploration and mining. Background technique [0002] At present, in the process of exploration and mining of coal and other mineral resources, it is often necessary to perform operations such as grouting and sealing of drilling holes in the formation. In actual construction, it is found that on the one hand, the strength of the grouting pipe itself is relatively small; It cannot be carried out due to the obstruction of objects, or the structure of the grouting pipe is damaged and the positioning error of the grouting pipe is relatively large, which seriously affects the work efficiency and quality of the grouting operation for the borehole. In view of this problem, Since there is no effective countermeasure equipment at present, the borehole can only be cleaned by high-pressure air or high-pressure water, and then the grouting...
