Description

Technical Field

[0001] The utility model relates to the technical field of mine surveying, in particular to a plumb bob installation and marking device for mine survey control points. Background Technique

[0002] Mine surveying plays a crucial role in mine construction and mining processes. It mainly involves surveying and mapping work for mine planning and design, exploration and construction, production and operation management, and mine abandonment. The main tasks of mine surveying include establishing a ground control network in the mining area, etc. In mine construction surveying, it provides surveying work for the construction of various projects, such as civil engineering surveying on the ground, underground control surveying and construction surveying, shaft orientation surveying and shaft elevation introduction surveying, shaft through surveying, etc. During mine surveying, control points need to be pre-buried.

[0003] Patent Application No.: 202223295118.0 proposes a plumb bob installation and marking device for mine survey control points, including a metal sleeve with a positioning disc fixed at the lower end. The positioning disc has a central circular hole in the form of a through hole, and the lumen of the metal sleeve communicates with the central circular hole; a sleeve gap is provided in the upper part of the metal sleeve; it also includes a metal measuring nail with the upper end penetrating into the central circular hole and the metal sleeve, and a connecting end is fixed at the lower end of the metal measuring nail; the connecting end has a transverse through hole at the end and a longitudinal rope hole at the end that communicates with the transverse through hole at the end and is used for installing a measuring wire rope; it also includes a hanging clamp connected to the connecting end. Using this device is convenient for accurate measurement and positioning during mine surveying construction, improving the accuracy of control points, improving measurement accuracy and measurement work efficiency. At the same time, because a hanging clamp for recording the position information of the control point where it is located is buried at the measurement control point, it can effectively prevent errors in the use of control points during measurement construction and avoid the occurrence of measurement technical accidents.

[0004] This device still has some deficiencies when in use. For example, it is necessary to first install the metal measuring nail and then install the measuring wire rope on the metal measuring nail, which is rather troublesome to install. Moreover, the measuring wire rope needs to be carried separately, which may get entangled and affect subsequent use. And after the measuring wire rope is installed, its length is not convenient to adjust, making it difficult to meet people's usage requirements. Content of the Utility Model

Two positioning bolts 6 are screwed and assembled on the mounting plate 5. The position of the mounting plate 5 matches that of the positioning holes 3. When installing the threaded nail 4, first align the positions of the positioning holes 3 and the positioning bolts 6, and move one end of the positioning bolt 6 into the positioning hole 3 by rotating the positioning bolt 6, which is convenient for limiting and fixing the threaded nail 4.

[0024] The upper surface of the adjustment box 8 is installed with an identification plate 10, which is used to record or mark relevant information of the control points, such as numbers, elevations, etc., to facilitate the surveyors to identify and record. An adjustment cavity 11 is opened inside the adjustment box 8. A rotating shaft 12 is rotatably installed inside the adjustment cavity 11. A winding roller 13 and a worm gear 14 are fixedly installed on the outer surface of the rotating shaft 12. A connecting rope 17 is wound around the worm gear 14. One end of the connecting rope 17 is fixedly installed on the outer surface of the worm gear 14. The other end of the connecting rope 17 extends to the outside of the adjustment box 8 and is fixedly installed with a plumb bob 18. A worm 15 is also rotatably installed inside the adjustment cavity 11. The worm 15 meshes with the worm gear 14.

[0025] By rotating the worm 15, the worm gear 14 is driven to rotate. The rotation of the worm gear 14 causes the winding roller 13 to rotate, thereby winding or releasing the connecting rope 17. When the connecting rope 17 is released, the plumb bob 18 descends under the action of gravity until the required height is reached. By adjusting the rotation direction and degree of the worm 15, the position of the plumb bob 18 can be precisely controlled. At the same time, when not in use, the connecting rope 17 can be wound up to prevent the connecting ropes 17 from being entangled and affecting the storage of the device.

[0026] Furthermore, one end of the worm 15 extends to the outside of the adjustment box 8. A knob 16 is fixedly installed at one end of the worm 15. By rotating the knob 16, it is convenient to drive the worm 15 to rotate.

The design of the installation frame 9 and the bolts enables the identification plate 10 to be conveniently replaced to adapt to different measurement requirements.

[0028] Furthermore, a guide wheel is rotatably installed inside the adjustment cavity 11. The connecting rope 17 is lapped on the outer surface of the guide wheel, which facilitates guiding the connecting rope 17 and ensures that the plumb point of the connecting rope 17 is at the center of the adjustment box 8.

[0029] Furthermore, a counterweight is fixedly installed on the bottom surface of the adjustment box 8, which is used to adjust the center of gravity of the adjustment box 8 and ensure the stability of the adjustment box 8.

[0030] Working principle: For the plumb bob installation and marking device of the mine survey control point, during use, first drill an installation hole at a predetermined position on the mountain body, then insert the threaded sleeve 1 into the installation hole and fix it. Next, rotate and install the threaded nail 4 inside the threaded sleeve 1. Align the positioning hole 3 with the positioning bolt 6, and move one end of the positioning bolt 6 into the positioning hole 3 by rotating the positioning bolt 6, which facilitates the limit fixation of the threaded nail 4. By rotating the knob 16, the worm 15 is driven to rotate. Due to the meshing relationship between the worm 15 and the worm gear 14, the worm gear 14 will rotate accordingly. The rotation of the worm gear 14 causes the roller 13 to rotate, thereby winding or releasing the connecting rope 17. When the connecting rope 17 is released, the plumb bob 18 descends under the action of gravity until the required height is reached. By adjusting the rotation direction and degree of the knob 16, the position of the plumb bob 18 can be accurately controlled. At the same time, when not working, the connecting rope 17 can be wound up to prevent the connecting ropes 17 from being entangled and affecting the storage of the device. The marking plate 10 is used to record or label relevant information of the control point, such as number, elevation, etc., which is convenient for surveyors to identify and record. The design of the mounting frame 9 and bolts enables the marking plate 10 to be easily replaced to meet different measurement requirements.
