A horizontal core drilling rig and its direction adjustment system

Abstract

The invention discloses a direction adjustment system for a horizontal coring drilling machine. The direction adjustment system includes at least three hydraulic winches and hydraulic direction adjustment loops which are connected with hydraulic motors of the hydraulic winches in one-to-one correspondence, wherein steel wire ropes of the hydraulic winches are connected with outer sleeves of the horizontal coring drilling machine, and the steel wire ropes and fixed points of the outer sleeves are arranged non-collinearly; the hydraulic direction adjustment loops are used for controlling the oilpressure of working ports of the hydraulic motors to adjust tension of the steel wire ropes; and a drill pipe is subjected to force at different application points, through combination of different tension of the steel wire ropes, the space positions of the fixed points are changed, thus the axis direction of the drill pipe, namely the drilling direction of the horizontal coring drilling machineduring drilling is changed, the purpose of adjusting the drilling direction of the horizontal coring drilling machine is achieved, and the working condition of the hydraulic winches adjusting the drilling direction is achieved. The invention further discloses the horizontal coring drilling machine including the direction adjustment system for the horizontal coring drilling machine.

Description

technical field [0001] The present invention relates to the field of hydraulic technology, and more specifically, relates to a direction adjustment system of a horizontal core drilling machine. In addition, the present invention also relates to a horizontal core drilling machine comprising the above-mentioned direction adjustment system of the horizontal core drilling machine. Background technique [0002] In the process of infrastructure construction such as roads, railways and water diversion projects, tunnel construction is often involved. Before tunnel excavation, geological exploration of the tunnel site is a necessary part of tunnel construction. [0003] In the prior art, a vertical core drilling rig is usually used to drill a hole vertically downward from the ground to obtain core samples of the formation to analyze the geological conditions of the tunnel. However, in areas where tunnels are deeply buried, it is difficult and costly to drill down from the ground to t...

AI Technical Summary

Problems solved by technology

[0004] However, the horizontal core drilling rig in the prior art only has a drilling function, and cannot adjust the drilling direction during the drilling process, so that the drilling route is limited

That is to say, the existing horizontal coring drilling rigs are only suitable for short-distance coring exploration. For long-distance coring, the path deviation will be too large, resulting in the inability to drill according to the requirements of the predetermined drilling route.
