Abstract

A kind of simple bore angle measuring scale, including angle marking plate, the angle marking plate marginal position are identified equipped with angle；Positioned at angle marking plate middle position, rotation is provided with measurement pipe, and the measurement pipe is a straight round tube, and both ends end is thinner.This device structure is simple, easy to use, cheap and for ease of maintenaince safeguard, is applicable in and several work environment.The measurement core school of duct angle in tunnel is realized by simple structure.

Description

A kind of simple bore angle measuring scale

Technical field

The utility model relates to a kind of bore angle core calibration equipment more particularly to a kind of simple bore angle measuring scales.

Background technique

It is required according to safety quality standard construction associated documents, working face should be equipped with inclinometer and carry out to the angle of anchor pole Detection, the MJY anchor angle tester now first having are suitable only for the detection of rectangular cross section support anchor rod, cannot detect crowned section construction Anchor pole, anchor cable.Also, electron detection device price is higher, and maintenance is complex, is not appropriate for synthetic job environment.

Utility model content

The purpose of this utility model is that overcoming the shortage of prior art place, it is simple to provide a kind of structure, easy to use Simple bore angle measuring scale, a kind of simple bore angle measuring scale described in the utility model developed by front man and At equipment is simple, but using effect is splendid, adapts to several work environment.

Equipment includes angle marking plate, and the angle marking plate marginal position is identified equipped with angle.

Positioned at angle marking plate middle position, rotation is provided with measurement pipe.The measurement pipe is a straight round tube, both ends End is thinner.

Further, the angle marking plate is semicircle, and angled mark is arranged in cambered surface edge position.

Further, the measurement pipe is the cannula structure with spring catch.

When the utility model is used, as drift section be arch, can by measurement pipe one end be inserted into alley way anchor rod aperture in, make band The measurement pipe of angled marking plate one end upward, by angle marking plate and the closely connected conjunction of tunnel contour line, directly reads measurement pipe and exists The data of angle marking plate.If drift section is rectangle, measurement pipe one end can be inserted into alley way anchor rod aperture, be made with angle The measurement pipe for spending marking plate one end downward, directly reads measurement pipe in the data of angle marking plate.The used time is waited in equipment, it can Measurement pipe is shunk, convenient for storage.

The beneficial effect of this equipment is: this device structure is simple, easy to use, cheap and for ease of maintenaince safeguard, fits With with several work environment.The measurement core school of duct angle in tunnel is realized by simple structure.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of simple bore angle measuring scale described in the utility model；

1- angle marking plate 2- measurement pipe

The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.

Specific embodiment

Referring to Fig.1, a kind of simple bore angle measuring scale described in the utility model, including angle marking plate 1, the angle 1 marginal position of marking plate is spent to identify equipped with angle.

Positioned at 1 middle position of angle marking plate, rotation is provided with measurement pipe 2.The measurement pipe 2 is a straight round tube, Both ends end is thinner.

Further, the angle marking plate 1 is semicircle, and angled mark is arranged in cambered surface edge position.

Further, the measurement pipe 2 is the cannula structure with spring catch.

When the utility model is used, as drift section be arch, can by 2 one end of measurement pipe be inserted into alley way anchor rod aperture in, make Measurement pipe 2 with angled 1 one end of marking plate upward, by angle marking plate 1 and the closely connected conjunction of tunnel contour line, directly reads measurement Data of the pipe 2 in angle marking plate 1.If drift section is rectangle, 2 one end of measurement pipe can be inserted into alley way anchor rod aperture, Make the measurement pipe 2 with angled 1 one end of marking plate downward, directly reads measurement pipe 2 in the data of angle marking plate 1.? Equipment waits for the used time, can shrink measurement pipe 2, convenient for storage.
