Description
Technical field
The present invention relates to a kind of mine working cross dimensions simple measurers, belong to underground survey technical field.
Background technique
Currently, the measurement of coal mine down-hole tunnel cross dimensions only uses a tape measure and a bamboo pole.In use, volume
Ruler is fixed on bamboo pole end, measures coal mine down-hole tunnel profile data, and pass through formula approximate calculation coal mine down-hole tunnel section
Area, due to only measuring two data in coal mine down-hole tunnel section highest point and widest point when measurement, error is larger, so, one
Kind of cross dimensions simple measurer that is easy, being easy production seem extremely it is necessary to, so that it is not only can satisfy requirement, but also
Cost can be saved.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a kind of mine working disconnected
Face size simple measurer has the characteristics that simple structure, easy to use, permanent durable, improves geological work efficiency, reduce
Measurement error.
Mine working cross dimensions simple measurer of the present invention includes protractor and scalable measuring rod, protractor
It is flexibly connected by shaft with the realization of scalable measuring rod, scalable measuring rod includes telescopic segment and fixed section, the back of fixed section
Face is equipped with fluorescent tube and power supply, and the top of telescopic segment is in arc-shaped, and top is equipped with circular hole, for drawing section configuration.
Wherein:
The circular hole is equipped with multiple.
The telescopic segment is than fixed segment length 5-10cm.
When measurement, measuring instrument of the invention is placed in mine working bottom surface, by shaft rotation measuring bar to tunnel wall surface,
And record its length, rotation one circle after, just can complete documentation drift section data, when the breviary shape for needing to draw section
When, drawing pen can be penetrated in the circular hole of telescopic segment, the graphing with the rotation of measuring rod.When in mine sight than it is darker when,
Fixed back mounted fluorescent tube and power supply can guarantee the accuracy of reading.
The present invention has the beneficial effects that
The configuration of the present invention is simple, easy to use, light portable, the measuring tool for not needing to borrow profession just can measure institute
Data are needed, geological work efficiency is improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
In figure: 1, protractor；2, shaft；3, power supply；4, fluorescent tube；5, fixed section；6, telescopic segment；7, circular hole.
Specific embodiment
The embodiment of the present invention is described further with reference to the accompanying drawing:
As shown in Figure 1, mine working cross dimensions simple measurer includes protractor 1 and scalable measuring rod, protractor 1
It is flexibly connected by shaft 2 with the realization of scalable measuring rod, scalable measuring rod includes telescopic segment 6 and fixed section 5, fixed section 5
The back side fluorescent tube 4 and power supply 3 be installed, the top of telescopic segment 6 is in arc-shaped, and top is equipped with circular hole 7, for drawing section shape
Shape, circular hole 7 be equipped with it is multiple, telescopic segment 6 is 5-10cm longer than fixed section 5.
