Problems solved by technology

[0003] However, in the process of using the existing technology, it is found that because the excavation face often has a lot of iron objects, and the iron objects are magnetic, which will seriously affect the accuracy of the compass, resulting in inaccurate setting of the horizontal angle between the drill hole and the center line, making the drilling accuracy The azimuth angle is finally given inaccurately

Abstract

The invention discloses a center line positioning device for a device for quickly giving a drilling azimuth angle, which comprises: a fixed plate and a first laser, wherein the first laser is arrangedon the fixed plate, and the central axis of the first laser is vertical to the front surface of the fixed plate; a calibration table which is fixedly connected to the upper portion of the fixed plate, wherein the upper surface of the calibration table is perpendicular to the front surface of the fixed plate; and a first gradienter which is arranged on the upper surface of the calibration table. The problem that in the prior art, whether laser emitted by a first laser coincides with the center line or not cannot be easily judged through naked eyes is solved.

Description

technical field [0001] The invention relates to the technical field of centerline positioning, in particular to a centerline positioning device and a using method for quickly specifying a drilling azimuth angle device. Background technique [0002] When constructing gas drainage drilling in Shimen (well lane) coal excavation and excavation working face or in the drilling field, it is very important to set the azimuth angle of the drilling hole, and the correct setting of the azimuth angle of the turning hole is the key to measure the control range of the drilling hole an important factor. In the prior art, the compass is usually used to directly set the horizontal angle between the borehole and the center line, and then the vertical angle between the borehole and the center line is given by the gradient gauge. After the horizontal angle and the vertical angle are given, the The azimuth of the borehole is obtained. [0003] However, in the process of using the existing tech...
