Description
Technical field:
This utility model relates to a kind of verifying device, relates in particular to a kind of overhead caving construction verifying device.
Background technology:
Adopt overhead caving at the beginning of underground mine usually to carry out in underground goaf, bore from goaf top plate upwards " yi word pattern "
One row's deep hole carries out charge explosion, forms presplitting groove, along with the propelling of work surface, is progressively caving, and blast hole parameter directly affects
Demolition effect.But owing to the factors such as the impact of underworkings working environment and survey tool restriction cause difficulty of verifying big, generally
In the case of be to use mine lamp light-illuminating, range estimation big gun hole is the most straight, smooth etc.；Or direct access inquiry rig work, or hold and compare
Short tamper is verified.Use said method to carry out verifying inaccurate, and the concrete angle in big gun hole cannot be drawn.
Utility model content:
The purpose of this utility model is to provide the overhead caving construction that a kind of simple in construction, convenience of verifying, precision are high to test
Aperture apparatus.
This utility model is implemented by following technical scheme: overhead caving construction verifying device, it includes that two are oppositely arranged
Semicircle Angle protractor, connect between two described semicircle Angle protractor either end and have horizontal columns, at two described semicircles
It is provided with fixing sleeve between in the middle part of shape Angle protractor, is fixed with bi-directional expansion bar in described fixing sleeve inner；Each described
The circle centre position of semicircle Angle protractor has the most vertically placed a jointed shaft, every described jointed shaft inner all described with adjacent
Fixed cover drum outer wall is vertically fixing to be connected, and the axis of two described jointed shafts is point-blank；On described fixing sleeve top
Portion is fixed with the instruction pin be arrangeding in parallel with described fixing sleeve axis, and described instruction pin points to described semicircle Angle protractor
Center.
Further, the described jointed shaft outside arbitrary described semicircle Angle protractor is bolted with locking nut.
Further, described bi-directional expansion bar side wall is provided with graduation mark.
Advantage of the present utility model: simple in construction, low cost；After bi-directional expansion bar is stretched over the longest insertion big gun hole, can
Directly read the degree of depth in big gun hole by graduation mark, after bi-directional expansion bar is inserted big gun hole, directly can be read inclining of big gun hole by instruction pin
Rake angle, can learn the degree of depth and the angle of inclination in big gun hole intuitively, convenient and swift；Level is made by the semicircle Angle protractor of regulation
The bubble of post is placed in the middle, and then improves measuring accuracy.
Accompanying drawing illustrates:
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is the left view of Fig. 1.
Semicircle Angle protractor 1, horizontal columns 2, fixing sleeve 3, bi-directional expansion bar 4, jointed shaft 5, instruction pin 6, locking nut
7, graduation mark 8.
Detailed description of the invention:
As depicted in figs. 1 and 2, overhead caving construction verifying device, it includes two semicircle Angle protractors being oppositely arranged
1, connect between two semicircle Angle protractor 1 either end and have horizontal columns 2, when semicircle Angle protractor 1 base is parallel to the ground
Time, the bubble of horizontal columns 2 is placed in the middle；It is provided with fixing sleeve 3, in each semicircle amount between in the middle part of two semicircle Angle protractors 1
The circle centre position of gusset 1 has the most vertically placed a jointed shaft 5, every jointed shaft 5 inner all with adjacent fixing sleeve 3 outer wall
Vertical fixing connection, and the axis of two jointed shafts 5 is point-blank, two pieces of semicircle Angle protractors 1 can synchronize around jointed shaft 5
Rotate；Being fixed with at fixing sleeve 3 top and fix the instruction pin 6 that sleeve 3 axis be arranged in parallel, instruction pin 6 points to semicircle
The center of shape Angle protractor 1；It is fixed with bi-directional expansion bar 4 inside fixing sleeve 3；Outside in office one semicircle Angle protractor 1
Jointed shaft 5 is bolted with locking nut 7, is provided with graduation mark 8 on bi-directional expansion bar 4 sidewall, it is simple to observe the degree of depth in big gun hole.
Operation instruction: first, is stretched over the longest by the bi-directional expansion bar 4 at fixing sleeve 3 top, aperture, big gun hole insert big gun
Inside hole, until contacting at the bottom of hole, big gun hole, now can directly be read the degree of depth in big gun hole by graduation mark 8；Then, elongation bi-directional expansion
Bottom bar 4, until contacting with ground；Screw out locking nut 7 again, rotate fixing sleeve 3, make the semicircle adjacent with indicating pin 6
Angle protractor 1 is towards tester；Finally, semicircle Angle protractor 1, when the bubble of horizontal columns 2 is placed in the middle, precession locking nut are rotated
7, make semicircle Angle protractor 1 be relatively fixed with fixing sleeve 3, now, instruction pin 6 indication scale is the angle of inclination in big gun hole.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
