Problems solved by technology

Drill bits with different diameters need to be used in staged construction during reaming, which reduces the damage of the drill bit to the mine wall to a certain extent, but the staged construction requires high stability of the drilling equipment, and there is a risk of azimuth deviation. The efficiency of hole construction is affected, so we propose a geological drilling anti-deviation device

Abstract

The invention discloses an anti-deviation device for geological drilling. The bottom of the rod is fixed with an electrical box, and the bottom end of the drill rod is fixed with a drill bit. The present invention can adjust the diameter of the drill rod arbitrarily through the fixed structure provided, so that the fixation of the drill rod is more firm. The length of multiple outriggers can be adjusted at will, which is suitable for fixing uneven ground. The infrared transmitter is equipped to emit infrared rays to accurately standardize the downward path of the drill pipe. The infrared sensor is equipped to sense the downward path of the drill bit. Whether it is consistent with the infrared ray, the pressure sensor on the inner wall of the electrical box is sensed by the pressure sensor. When the drill bit deviates, it will cause local pressure on the electrical box, so that the pressure sensor can detect.

Description

technical field [0001] The invention relates to an anti-deviation device, in particular to an anti-deviation device for geological drilling. Background technique [0002] Drilling or prospecting is the use of deep drilling mechanical engineering technology to mine underground or seabed natural resources, or to take real-time stratum sections and take physical samples to provide experiments to obtain relevant data, etc. [0003] In the process of underground mine operation, it is often necessary to carry out drilling and reaming drilling construction on mineral layers, so as to facilitate the better development of minerals. Drill bits with different diameters need to be used in staged construction during reaming, which reduces the damage of the drill bit to the mine wall to a certain extent, but the staged construction requires high stability of the drilling equipment, and there is a risk of azimuth deviation. The hole construction efficiency is affected, so we propose a geo...
