Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the preferred embodiment structural representation that cradling piece is used in mine surveying of the present utility model.
Among the figure: 11. main parts, 12. bayonet sockets, 13. first through holes, 14. second through holes.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, mine surveying of the present utility model cradling piece preferred embodiment, cradling piece comprises main part 11, and the cross section of main part 11 is rounded, and the one end is in order to install prism, and the other end can be installed on tripod.
The prism that adopts in the present embodiment is wholecircle suspension type prism, preferably adopts GRZ4-360 ° of prism of Lycra company, and it is a kind of reflecting prism of full myriabit, is made up of six reflectings surface.
The surface of one end of main part 11 is along circumferentially offering bayonet socket 12, and wholecircle suspension type prism can be sheathed and be fixed on this bayonet socket 12.
The end of the other end of main part 11 relative bayonet sockets 12 offers first through hole 13 along axis direction, and the sidewall of main part 11 also offers second through hole, 14, the first through holes 13 and second through hole 14 is communicated with.
Second through hole 14 runs through main part 11 along the direction of main part 11 diameters, thereby forms the hole of two symmetries on the surface of main part 11.First through hole 13 and second through hole 14 are communicated with, and therefore rope can be equipped with first through hole 13 and draw from second through hole 14 from the sidewall of main part 11, and then can be fixed in the roof in hole, ore deposit and then realize hanging and measure.
Preferably, use fine turning lathe, offer the hole of a diameter 3.0mm, dark 20cm at the end face of cradling piece along the direction of main part 11 axis, offer the hole that a diameter is 3.0mm simultaneously in vertical with it side, and it is communicated with the hole of axis direction.
Above-mentioned wholecircle suspension type prism cooperates total powerstation in the application of underground survey:
1, measurement of angle
Measurement of angle is the important process in the underground survey, also is key job.The height of angle-measurement accuracy directly has influence on azimuthal size, thereby influences the weakest point and the error on weak limit.Because float coal and ponding are more in the driving face of down-hole, it is more that the while tunnel is narrow, personnel walk about, so require surveying work necessary fast, accurate.The angle value of total powerstation all is presented on the instrument screen, so can read very soon, has reduced reading error and reading duration.And when adopting wholecircle suspension type prism to be the forward sight prism, because it adopts the suspension prism of cradling piece method for punching, make surveyor's beacon center and prism center vertical; This prism is heavier and for fairing designs more in addition, has reduced distinguished and admirable influence, has finally weakened the influence of target eccentric error in the angle measurement process greatly, thereby has improved the precision of measurement of angle.
2, the length of side is measured
The employing total powerstation cooperates the range finding of wholecircle suspension type prism, can not be subjected to the influence of prism rotation, the flat distance of transient measurement, the discrepancy in elevation and oblique distance, and distance accuracy improves greatly, and Measuring Time significantly reduces.
3, the measurement of higher degree
When adopting wholecircle suspension type prism to carry out the measurement of higher degree, can give up the traditional triangle measurement of higher degree and adopt that measuring accuracy is higher, speed faster the electro-optical distance measurement height traverse measure.Can use the total station survey zenith distance again by after directly measuring the point-to-point transmission inclination length of side, import the high and surveyor's beacon height of instrument at last, in the hope of the tested point elevation.What must illustrate is that when adopting wholecircle suspension type prism to be the forward sight prism, the surveyor's beacon a large amount need add a constant after getting the prism upper edge again, this is because the instrument aiming is the prism center, the distance of centre distance upper edge is a constant, is example with Lycra GRZ4-360 ° prism, and its constant is 50mm.
In sum, we adopt total powerstation to cooperate wholecircle suspension type prism to instruct the underworkings driving, and it is poor that all working face angle closing error of traverse of formation, relative coordinate mis-tie all are far smaller than the 30d level undershaft traverse survey precision limit of regulation in the 5 coal mine survey rules 6.Facts have proved, by wholecircle suspension type prism technique is applied in the underground survey, makes total powerstation more convenient in the application of down-hole, thereby improved measuring accuracy, alleviated labour intensity, improved efficiency.
Be enlightenment with above-mentioned foundation desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
