Embodiment Construction

[0019] A laser slope pointing instrument according to the present invention comprises a structural frame 1, a flat mirror 2, a vertical dial 3 and two ring levels,

[0020] Such as figure 1 , 2 As shown, the annular level includes an annular glass tube filled with half of the colored liquid, generally red liquid, two annular levels are arranged vertically and fixed in the structural frame 1, and the two annular levels are perpendicular to each other, wherein , the ring level I4 is fixed along the left and right directions of the structural frame 1, and the ring level II5 is fixed along the front and rear directions of the structural frame 1.

[0021] The structural frame 1 is made of a section of 20cm square tube metal, which is used to fix the ring level, the plane mirror 2 and the vertical dial 3 . Two circular levels are fixed inside the structural frame 1 and remain stationary with the structural frame 1. Among them, the circular level I4 is used to indicate the horizont...

Abstract

The invention discloses a varying-slope laser orientation instrument which comprises a structure frame, a plane mirror, a vertical circle and two annular level gauges, wherein each annular level gauge comprises an annular glass pipe filled with a color liquid by half, the two annular level gauges are vertically fixed in the structure frame and are perpendicular to each other, the annular level gauge I is fixed in the left-right direction of the structure frame, and the annular level gauge II is fixed in the front-rear direction of the structure frame; the plane mirror is arranged in the horizontal direction, the middle of the plane mirror is fixed to a horizontal shaft which is supported at two ends of the structure frame and horizontally arranged in the front-rear direction of the structure frame, and the vertical circle is perpendicularly fixed to a rotary shaft. According to the varying-slope laser orientation instrument, a laser transmission direction is changed by an included angle between the plane mirror and a horizontal plane, and the included angle between the plane mirror and a horizontal plane is controlled by the vertical circle, so that the included angle between a laser beam and the horizontal plane is controlled, and the purpose of laser irradiation according to the design slope is achieved; the mounting is simple and easy; in addition, the accuracy is high.

Description

technical field [0001] The invention relates to a laser pointing device used when driving an underground roadway in a coal mine, in particular to a laser pointing device used when the roadway changes slope. Background technique [0002] Due to the development of science and technology, modern mines generally use laser pointing instruments as tunneling pointing tools in roadway excavation. The laser pointing instrument is a measuring instrument for direction positioning developed by using the characteristics of laser beam concentration and good coherence. It has a beam Good quality, stable work, convenient installation and adjustment, etc., have been widely used in the survey work of various mines. [0003] However, before installing the laser pointing device, it is necessary to use a theodolite or a total station to mark a group of centerline points in the roadway, and each group of centerline points is three, namely A, B, and C. And mark the height of the waistline on the ...
