Description
Technical field
The utility model is related to mine down-hole tunnels to tunnel ore pressure monitor technical field, and in particular to arrive a kind of roof delamination
Instrument reading plotter.
Background technology
Roof separation indicator is a kind of special monitoring instrument of monitoring roof strata movement.It can show rock-bolt length range
The absciss layer situation of roof strata outside interior and anchor pole co-extensive, determining anchor pole is provided for colliery engineering technical staff and testing staff
Length, tensile strength, understand used in anchor pole and rationality, economy and the scientific basis needed, to effectively prevent
The only generation of caving-in accident, it is ensured that Safety of Coal Mine Production.The monitoring of top plate can't realize electronic program, can only lean on
Existing roof separation indicator reads to observe the situation of change in its tunnel, to take practicable reinforcement supporting measure.
Roof separation indicator is all installed in the center in tunnel, and tunnel is generally 3.2 to 3.5 meters, is provided according to safety regulations in coal mine every
25-50 meters are arranged one group, and all separation indicators belonging to mine need to observe once for every 5 days, due to being limited by head-room, observe work
One group of 2 people is needed to shoulder an aluminum alloy ladder（Weight is 15KG）Several kilometers on foot daily, and a people is helped everywhere
One people of ladder ascends a height operation viewing reading, and physical demands is big, operation of ascending a height is unfavorable for safety.
Invention content
In order to make up above-mentioned the deficiencies in the prior art, the utility model proposes a kind of roof separation indicator reading plotters, in essence
While quasi- reading, operating procedure is simplified, ensures staff's job safety.
The purpose of this utility model is achieved through the following technical solutions：A kind of roof separation indicator reading plotter, including
Back, roof separation indicator, tubular type readout instrument are characterized in that：Back is equipped with metal mesh, and metal mesh is equipped with can
Mobile magnet；Connect metallic rod below magnet, the lower end of metallic rod is equipped with double plane magnifying glass, double plane magnifying glass with
The graduation apparatus of roof separation indicator is arranged in parallel；The lower end of double plane magnifying glass is flexibly connected with the upper end of tubular type readout instrument, pipe
Angle between formula readout instrument and double plane magnifying glass is 90 ° -135 °, is looked in the distance equipped with small focal length in end pipe under tubular type readout instrument
Mirror；Tubular type readout instrument bottom is equipped with fixed tripod.
Further, tubular type readout instrument length is two meters.
Further, the lower end of double plane magnifying glass is flexibly connected with the upper end of tubular type readout instrument by folding.
The utility model has the beneficial effects that：While accurate reading, operating procedure is simplified, ensures that staff makees
Industry safety, it is ensured that Safety of Coal Mine Production.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In Fig. 1：Back 1, roof separation indicator 2, graduation apparatus 3, metal mesh 4, magnet 5, metallic rod 6, double plane are put
Big mirror 7, folding 8, tubular type readout instrument 9, small focus binocular 10, fixed tripod 11.
Specific implementation mode
Concrete structure such as Fig. 1, the present embodiment is as follows：3.5 meters of head-room, back are equipped with metal mesh 4, metal mesh
4 are equipped with moveable magnet 5；5 lower section of magnet connects metallic rod 6, and the lower end of metallic rod 6 is equipped with double plane magnifying glass 7, double
Times plane magnifying glass 7 and the graduation apparatus 3 of roof separation indicator are arranged in parallel, and double plane magnifying glass 7 is by 2 high scale of roof separation indicator
Watch relatively sharp on table 3 after reading amplification, metallic rod 6 ensures the minute surface of double plane magnifying glass 7 with roof separation indicator 2 always
Keeping parallelism, to avoid angular deviation from causing read untrue, there are error phenomenons；The lower end of double plane magnifying glass 7 passes through
Folding 8 is flexibly connected with the upper end of long two meters of tubular type readout instrument 9, the angle between tubular type readout instrument 9 and double plane magnifying glass 7
Degree is 90-135 °, and 9 lower end inside of tubular type readout instrument is equipped with small focus binocular 10；9 bottom of tubular type readout instrument is connected and fixed three feet
Frame 11.
