It is dynamic to be connected in slideway, inside groove 12 is offered on each limited block, the fastening nut and the detachable fixation of limited block are even
It connects.
Embodiment 2 the difference from embodiment 1 is that: the limited block includes sliding block 13, threaded post 14 and locking nut
15, the sliding block be located at slideway be flexibly connected with ruler body in realize being flexibly connected of limited block and ruler body, enable limited block
It moves along a straight line along slideway, the threaded post is fixedly connected on sliding block upper surface, and the inside groove is provided with threaded post center and has
There is certain depth, the locking nut is threadedly coupled with threaded post, and locking nut lower surface can be with the ruler body of slideway two sides
It is in close contact, the fastening nut is threadedly coupled with threaded post, and fastening nut lower surface can be close with locking nut upper surface
Contact
Embodiment 3 the difference from embodiment 1 is that: the ruler body is divided into two parts, and it is fixed to be equipped between two parts ruler body
Position pin 16.
It may be noted that the selection of ruler body gently, while will need to guarantee anticorrosive rust-proofing, and in the presence of a harsh environment in the utility model
It is unlikely to deform.Position limiting ruler scale is accurate, can accurately determine two plumb bob wire spacing of underground.Specifically, using aluminum alloy materials
Production, material is light, corrosion-resistant, and is unlikely to deform in the environment of pit shaft water drenching increase, temperature increase.Ruler body can be one
It is whole, two parts can also be divided into and positioning pin is installed in centre, so that ruler body can doubling, the specific can be that two
Ruler-separating body by positioning pin realize it is detachable be fixedly connected, be also possible to two ruler bodies and be flexibly connected, when spacer pin insertion
Position is fixed.Ruler body is referred to flexible rod principle setting, guarantees to shrink freely, and guarantees fixed under position limiting ruler full length.
The inside groove opened up on limited block is adapted with steel wire size, and fastening nut is used to steel wire vertical line being fixed on limited block, specifically
Using embodiment 2, screw locking nut and locking nut contact with the ruler body of slideway two sides, thus fixation
Sliding block, steel wire vertical line are located above locking nut after passing through inside groove, screw fastening nut and compress steel wire, guarantee that steel wire is fixed limit
Position.Limited block can move along a straight line along slideway, and scale is used to measure the spacing of two steel wires.
Use step:
(1) two steel wire vertical lines of free suspension are horizontal to orientation from well, immerse in the bucket equipped with stabilizing solution, and on ground
Table measures the distance s and azimuth angle alpha of two steel wire vertical lines.
(2) after two steel wire vertical lines are stablized, two steel wire vertical line distance s 1 and azimuth angle alpha are measured at the horizontal place of orientation
1, and compare the error between earth's surface institute measured data.
(3) position limiting ruler is installed, two steel wire vertical lines are separately mounted in the inside groove of two limited blocks, position limiting ruler is passed through
On scale, the spacing of two steel wire vertical lines is subject to strict control and consistent with earth's surface, after stablizing, the survey at orientation level
Two steel wire vertical line distance s 2 and azimuth angle alpha 2 are obtained, and compares the error between earth's surface institute measured data.
(4) error between above-mentioned α 1 and α is the trend of purchasing error used before position limiting ruler, and the error between α 2 and α is
To use the trend of purchasing error after position limiting ruler.
It is required according to " coal mine survey regulation ", mine geometric orientation invests error theta (θ=± e ρ/c, ρ is constant 206265 ")
It should not exceed ± 30 ", that is, set two cultellation steel wires and hang down wire spacing in the case where 2m, 3m, 4m, then setting point error mutually should be
0.3mm,0.45mm,0.6mm.The utility model is used when copper mine service well -1000m middle section ingate orients, and measures work
In freely hanged by earth's surface and put that two steel wire vertical lines are horizontal to the middle section -1000m orientation, and earth's surface measures two steel wire vertical line distance s and is
1.9m, azimuth angle alpha are 270 ° 00 ' 00 ".The plumb bob for fitting weight is hung up in steel wire lower end, and it is immersed to the bucket for filling stabilizing solution
In, stop blower operating, it is 1.9038m, azimuth angle alpha 1 that two steel wire vertical line distance s 1 are measured when steel wire vertical line amplitude of oscillation very little
It is 270 ° 00 ' 56.46 ", i.e., in the case where position limiting ruler is not used, by mine shaft depth, drips, the shadow of the factors such as temperature, air-flow
Ringing the lower trend of purchasing error is 56.46 ".
Under same environment, reduces ingate air-flow adding air door, increases plumb bob weight and enter stabilizing solution progress
Stablize plus water deflector cover carry out under the measures such as water blocking, then by this position limiting ruler to two cultellation steel wires at downhole orientation level into
Row limit, has re-started measurement work.Two steel wire vertical line spacing at the level of the middle section -1000m are limited by position limiting ruler
Be made as 1.9m, so limit steel wire by air-flow, drip etc. under the influence of swing, measuring two steel wire vertical line distance s 2 is
1.9007m, azimuth angle alpha 2 are 270 ° 00 ' 18.69 ".As can be seen that reducing unfavorable factor using position limiting ruler
Influence to plumb bob line setting point error provides accurate benchmark for the developing in underground middle section or two wells/more wells holing through survey, from
And improve the quality of engineering construction.
