Description

Technical Field

[0001] The utility model relates to the technical field of underground measurement point signs, in particular to a fixing device for underground measurement point signs. Background Technique

[0002] Gold mining refers to the development and excavation process of gold deposits. Mine surveying is an important basic technical work indispensable in the process of mining development. Underground surveying is the top priority of mine surveying and an important basis for mine production. Its function accompanies the development, tunneling, and mining of the mine until the end, with the characteristics of a long service life, a large quantity, and a great role in serving the mine. The measurement control points that make up the underground are important signs for underground measurement control. The existing underground measurement point signs are simply fixed by expansion bolts, steel wires, and nails. The lack of a specific hanging position for the steel wire leads to a low coincidence degree between the center points of the expansion bolts and the nails. When high-precision observation data is required, the instrument cannot be accurately centered, and external environmental, human, and other factors will affect the embedding of the control points, thereby reducing the accuracy of measurement data and the efficiency of measurement work. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fixing device for underground measurement point signs in view of the deficiencies of the prior art, so as to solve the problems proposed in the above background technique. The existing underground measurement point signs are simply fixed by expansion bolts, steel wires, and nails. The lack of a specific hanging position for the steel wire leads to a low coincidence degree between the center points of the expansion bolts and the nails. When high-precision observation data is required, the instrument cannot be accurately centered, and external environmental, human, and other factors will affect the embedding of the control points, thereby reducing the accuracy of measurement data and the efficiency of measurement work.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for underground measurement point signs, including an adjustment and alignment structure, and an adjustment and limit structure is fixed on the adjustment and alignment structure;

[0005] The adjustment and alignment structure includes a connecting cylinder with a hollow interior, and a slide rod passing through the slider is fixed inside the connecting cylinder through a connecting block. At the same time, a bearing plate for facilitating the rotation adjustment of the first threaded rod is fixed between the sliders;

[0006] The bottom of the first threaded rod is provided with a first threaded cylinder, and the first threaded cylinder is fixed to the lower part inside the connecting cylinder through a fixing ring.

[0007] By adopting the above technical solution, the inner and outer rings are installed and fixed by the provided fixing ring.

[0008] Preferably, a cross plate is fixed to the bottom of the first threaded rod, and a sleeve rod is installed in a matching manner at the bottom of the cross plate.

[0009] By adopting the above technical solution, the sleeve rod is provided to achieve matching connection.

[0010] Preferably, the adjusting and limiting structure includes a convex platform plate fixed on the connecting cylinder, a second threaded rod fixed on the convex platform plate, and a second threaded cylinder penetrating through the surface of the second threaded rod.

[0011] By adopting the above technical solution, the convex platform plate is provided to achieve two-way fixed installation.

[0012] Preferably, the second threaded cylinder is rotatably installed with a connecting plate through a mounting bearing, a through-hole concave block is fixed above the connecting plate, and the through-hole concave blocks are rotatably connected through a connecting pin with a double-hole connecting plate. The other through-hole concave block and the adjusting plate are respectively fixed and rotatably connected above the second threaded rod.

[0013] By adopting the above technical solution, the double-hole connecting plate is provided to achieve two-way rotational connection.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: The fixing device for underground measurement point marks,

[0019] (1) In this case, by providing the adjusting and limiting structure, it solves the problem that the existing underground measurement point marks are simply fixed by expansion screws, steel wires and nails. Since the steel wire has no specific hanging position, the coincidence degree of the center points of the expansion screws and the nails is not high. When high-precision observation data is required, the instrument cannot be accurately centered, and external environment, human factors, etc. will affect the embedding of the control points, thereby reducing the accuracy of measurement data and the measurement work efficiency. When the underground measurement point mark needs to be installed, the operator first drills an installation hole above the underground. At this time, the operator holds the convex platform plate and rotates the second threaded cylinder to rotate under force. When the second threaded cylinder rotates under force, it drives the connecting plate and the through-hole concave block to move upward synchronously under force. When the through-hole concave block moves upward, it drives the adjusting plate to rotate and adjust under force through the double-hole connecting plate. When the adjusting plate rotates and adjusts under force and contacts the inner wall of the installation hole, the overall adjusting and limiting structure is installed and fixed;

[0020] (2) By setting an adjustment and alignment structure, the above problems can be solved. When the individual sleeve rods have different heights, the operator rotates the cross plate to drive the first threaded rod to rotate under force. When the first threaded rod rotates under force, the lifting height distance between the cross plate and the sleeve rods is changed, and all the sleeve rods can be kept at the same height. When the device needs to be measured, the sleeve rod is removed, and the measuring device is aligned with the central hole at the bottom of the cross plate for measurement.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fixing device for underground measurement point marks, as Figure 1 , Figure 2 and Figure 3 shown, including an adjustment and alignment structure 1. The adjustment and alignment structure 1 includes a connecting cylinder 101 with a hollow structure inside, and a slide bar 102 passing through the slide block 103 is fixed inside the connecting cylinder 101 through a connecting block. At the same time, a bearing plate 104 convenient for the rotation adjustment of the first threaded rod 105 is fixed between the slide blocks 103. The bottom of the first threaded rod 105 is provided with a first threaded barrel 106, and the first threaded barrel 106 is fixed to the lower part inside the connecting cylinder 101 through a fixed ring 107. Among them, the above components are set to form a rotary lifting and sliding adjustment structure, and the rotary lifting and sliding structure formed by the above components effectively changes the lifting and sliding adjustment distance range of the first threaded rod 105.

[0027] Further, at the bottom of the first threaded rod 105, a cross plate 108 is fixed, and a sleeve rod 109 is installed at the bottom of the cross plate 108. Among them, the centers of the first threaded rod 105, the sleeve rod 109, the first threaded cylinder 106, and the first threaded rod 105 are always on the same axis. When the centers of the above-mentioned components are always on the same axis, it can avoid the influence of the non-uniform center of the above-mentioned components on the subsequent measurement results and measurement accuracy. The first threaded rod 105 and the cross plate 108 are arranged in a "T" shape. When the two are arranged in a "T" shape, it not only reflects the simplicity of the installation of the above-mentioned components, but also reflects the synchronous force-bearing rotation adjustment of the above-mentioned components. And when the connection shape of the two is arranged in a "T" shape, it also reflects the coaxial and concentric effects of the two at the same time.

[0028] As Figure 4 shown, an adjustment limiting structure 2 is fixed on the adjustment alignment structure 1. The adjustment limiting structure 2 includes a boss plate 201 fixed on the connecting cylinder 101, and a second threaded rod 202 is fixed on the boss plate 201. At the same time, a second threaded cylinder 203 is penetrated through the surface of the second threaded rod 202. The second threaded cylinder 203 is rotatably installed with a connection disk 204 through a mounting bearing, and a through-hole concave block 205 is fixed above the connection disk 204. At the same time, the through-hole concave blocks 205 are rotatably connected to a double-hole connecting plate 206 through a connecting pin. Another through-hole concave block 205 and an adjustment plate 207 are respectively fixed and rotatably connected to the upper part of the second threaded rod 202. There are 4 groups of through-hole concave blocks 205, and the through-hole concave blocks 205 are arranged in a circular array with respect to the connection disk 204. By using 4 groups of the above-mentioned components and 3 through-hole concave blocks 205 in a single group, when there are multiple of the above-mentioned components, it can ensure the folding and unfolding adjustment of the adjustment plate 207. By changing the folding and unfolding adjustment of the adjustment plate 207, it is effective to facilitate the contact fixation of the adjustment plate 207 to the drilling position and also facilitate the subsequent quick disassembly and separation of the overall measurement point marks.

[0029] In the above solution, when the underground measurement point marker needs to be installed, the operator first drills an installation hole above the underground. Then, the operator holds the boss plate 201 and rotates the second threaded cylinder 203, which is forced to rotate. When the second threaded cylinder 203 rotates under force, it drives the connecting plate 204 and the through-hole concave block 205 to move upward synchronously under force. When the through-hole concave block 205 moves upward, it drives the adjusting plate 207 to rotate and adjust under force through the double-hole connecting plate 206. When the adjusting plate 207 rotates and adjusts under force and contacts the inner wall of the installation hole, the overall adjusting and limiting structure 2 is installed and fixed. When it is found that the heights of some of the sleeve rods 109 are different, the operator rotates the cross plate 108 to drive the first threaded rod 105 to rotate under force. When the first threaded rod 105 rotates under force, the lifting height distance between the cross plate 108 and the sleeve rods 109 is changed, so that all the sleeve rods 109 can be kept at the same height. When the equipment needs to be measured, the sleeve rod 109 is removed, and the measuring equipment is aligned with the central hole at the bottom of the cross plate 108 for measurement. When a plumb bob needs to be suspended, the sleeve rod 109 cannot be removed. The plumb bob is vertically installed at the bottom of the sleeve rod 109 to ensure that the central axes of the sleeve rod 109 and the plumb bob are the same.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
