Abstract

The invention provides a semicircular built-in counterweight type slope gauge applicable to a heading face in the pit, which belongs to the field of measuring of a head-on slope during roadway excavation in the pit. The slope gauge is brought forward directed at the problems of great errors of measurement data and influence on reading effects of a conventional slope gauge during measuring in the pit. A main technical scheme in the invention is as follows: the semicircular built-in counterweight type slope gauge comprises a hollow semicircular housing with embedded scales, a center of a circle, the scales arranged on the inner wall of the housing, thread hanging plates, thread holes, an automatic thread winding device, a cotton rope and a counterweight, wherein a vortex rotary spring and a thread winding holder are arranged in the automatic thread winding device, the thread hanging plates are respectively arranged at two sides of the housing corresponding to the scale of 90 DEG, the thread holes are arranged at central positions in the thread hanging plates, the cotton rope is connected with the thread winding holder in the automatic thread winding device through the thread holes in the thread hanging plates, and the counterweight is hung at the center of the circle of the housing. The semicircular built-in counterweight type slope gauge provided by the invention has the following beneficial effects: low cost, a simple structure, uneasy wearing of the scales, convenience in tagline survey, no influence by environmental factors like ventilating current and fast and accurate measurement.

Description

A kind of semicircle built-in Weight type tilt gauge that is applicable to meet head in the down-hole

Technical field

Meet head on when the invention belongs to underground tunneling roadway to be specifically related to a kind of semicircle built-in Weight type tilt gauge that is applicable to meet head in the down-hole in the slope measuring field.

Background technology

At present, widely used tilt gauge because coal seam line or rock stratum line localized variation are big, needs the equal inclination angle of backguy lining when underground survey, and is easy to be subjected to Effect of Environmental such as air-flow when measuring; Another round liquid tilt gauge because the adhesive attraction between liquid and the shell causes the measurement data error big, influences the reading effect.

Summary of the invention

Factors such as the objective of the invention is provides a kind of can effectively the solution to be subjected to wind speed when measuring the gradient at above-mentioned the deficiencies in the prior art, adhesion and bringing inconvenience in a kind of semicircle built-in Weight type tilt gauge that is applicable to meet head in the down-hole of drawbacks such as reading, measurement data error are big.

For achieving the above object, the technical solution used in the present invention: a kind of semicircle built-in Weight type tilt gauge that is applicable to meet head in the down-hole, comprise hollow semicircle shell 5, the center of circle 3 of embedded scale and be arranged on scale 6 on the outer casing inner wall, it also comprises thread gripping-board 1, through wires hole 2, automatic line receiver 7, cotton rope 8, weight 4, and being provided with vortex in the described automatic line receiver changes spring 9 and change coil holder 10; Described thread gripping-board 1 is separately positioned on the both sides of shell 5 corresponding 90 ° of scales, described through wires hole 2 is arranged on the center of thread gripping-board 1, described cotton rope 8 is connected by the commentaries on classics coil holder 10 in the through wires hole 2 on the thread gripping-board 1 and the automatic line receiver 7, and described weight is suspended on 3 places, the center of circle of shell.

Compared with prior art, the invention has the beneficial effects as follows: cost is low, simple in structure, scale is not easy to wear, is convenient to backguy and measures, and is not subjected to Effect of Environmental such as distinguished and admirable, measures quick and precisely.
