Embodiment 1

[0028] Embodiment 1: as Figure 1-Figure 6 As shown, a simple protractor for mine borehole angle measurement includes a dial 1, an outer telescopic rod 2, an inner telescopic rod 4 and a rotating shaft 6, and the outer telescopic rod 2 is connected to the angle dial 1 through the rotating shaft 6. In the center, its internal structure is a cavity 13 with an upper side opening, and the inner telescopic rod 4 is located in the cavity 13 of the outer telescopic rod 2 , and can rotate out of the cavity 13 around the rotating shaft 6 .

[0029] Preferably, the above-mentioned outer telescopic rod 2 includes an outer tube-11 and a plurality of inner tubes-3 which are inserted into the outer tube-11 and are sequentially socketed. The cross-sections of the outer tube-11 and the inner tube-3 are both U-shaped. The U-shaped open end is provided with a limiting platform 17 inward to prevent the inner tube from coming out. The outer tube 11 is rotatably connected to the rotating shaft 6, ...

Embodiment 2

[0034] Embodiment 2: a kind of operation method of the simple and easy protractor that is used for mine borehole angle measurement, this method comprises the following steps:

[0035] (1) Clean the upper surface of the angle dial;

[0036] (2) Pull out the inner telescopic rod through the pull ring, and pull out the inner tube of the outer telescopic rod and the inner telescopic rod through the pull ring 1 and the pull ring 2 respectively;

[0037] (3) Keep one of the inner telescopic rod and the outer telescopic rod parallel or coincident with the central plane of the roadway;

[0038] (4) Turn the other telescopic rod to the drill hole;

[0039] (5) At this time, read out the angles X1 and X2 of the inner telescopic rod and the outer telescopic rod on the angle dial;

[0040] (6) The angle between the inner telescopic rod and the outer telescopic rod is the absolute value of the difference between X1 and X2. If one of the telescopic rods has an angle of 30 degrees and the ...

Abstract

The invention discloses a simple angulometer for measuring a mining drilling angle and an operation method thereof. The simple angulometer comprises an index dial, an outer flexible rod, an inner flexible rod and a rotating shaft, wherein the outer flexible rod is connected with the center of the index dial through the rotating shaft; a cavity with an opening on the upper side is arranged as the inner structure of the outer flexible rod; the inner flexible rod is located in the cavity of the outer flexible rod and can be rotated out of the cavity around the rotating shaft. According to the invention, the two flexible rods are arranged on the index dial and the angle is limited by rotating the two flexible rods, so that the angles can be conveniently and quickly measured; the angle difference along the horizontal direction can be quickly calculated by calculating the difference between the two flexible rods; the measurement is convenient and simple; the measuring result is accurate; the use is convenient; the problems of difficulty in measuring along the horizontal direction by adopting a normal line method, complex use of the normal line method, larger error and inconvenience in use are effectively solved; the simple angulometer has the characteristics of simple structure and low cost.

Description

technical field [0001] The invention belongs to an angle measuring instrument in the mining field, and in particular relates to a goniometer for measuring angle changes in the horizontal direction of mine borehole angles, and also relates to a simple goniometer for mine borehole angle measurement method of operation. Background technique [0002] In the process of measuring roadway orientation and drilling in coal mines, it is often necessary to measure the angle in the horizontal direction and the inclined direction. The existing goniometer is only convenient for measuring the angle value in the inclined direction, and there is no instrument for the angle change in the horizontal direction. available. At present, the vertical line method is mainly used to measure the angle in the horizontal direction. Using the vertical line method is cumbersome, has large errors, and is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the pr...
