Description

Technical Field

[0001] This utility model relates to the field of underground surveying, and in particular to a positioning device for underground surveying. Background Technology

[0002] Underground surveying refers to all surveying work conducted within a mine during its construction and production phases. It primarily involves the advancement, development, and connection of tunnels. In the design of tunnel development and mining engineering, there are clear regulations and requirements regarding the geometric elements of the tunnels, such as their starting point, ending point, direction, slope, and cross-sectional specifications. Underground surveying is a crucial link in ensuring safe production during mine construction and is an important and rigorous technical task. It is a vital means for coal mines to improve production technology management and achieve safe production. Underground surveying work mainly includes centerline marking, extension, traverse surveying, and elevation measurement. The space for underground surveying encompasses various tunnels and mining areas. Due to the narrowness of the tunnels, and the passage or movement of various pipelines, vehicles, and even pedestrians and ventilation systems, underground surveying is extremely complex.

[0003] When conducting underground surveying operations, it is necessary to measure the vertices. Therefore, a positioning device is needed to place the surveying instrument to achieve the purpose of fixed-point surveying. In the authorized Chinese utility model patent "Announcement No.: CN217082060U, Title: A Roadway Surveying Device Used in Mines", a storage slot can temporarily store and fix the tripod support frame and the surveying instrument body, which is convenient for transportation and carrying. However, in the above application, the surveying instrument lacks a fixing structure when in use, which makes the surveying instrument very easy to shake or even tip over, affecting the underground surveying work. In addition, for the convenience of movement, wheels are set at the bottom of the device, which makes the device easy to slide on the ground with a certain inclination angle, affecting the accuracy of the surveying. Utility Model Content

This prevents the downhole mapping instrument from shaking during mapping, which would affect the mapping accuracy and prevent impact on the accuracy of downhole fixed-point mapping. At the same time, when installing the downhole mapping instrument, the anti-slip component automatically contacts the ground under the action of its gravity, increasing the friction between the device and the ground, thereby increasing the stability of the device. This allows the device to adapt to ground with a certain tilt angle, increasing the stability of the mapping instrument and expanding the adaptability range of the downhole mapping fixed-point device.

[0025] In this technical solution, the bidirectional threaded columns on both sides can be rotated synchronously by using a drive component.

[0026] Preferably, the top end of the bidirectional threaded column is rotatably connected to the top of the inner cavity of the support side frame, the bottom end of the bidirectional threaded column is rotatably connected to the bottom surface of the support side frame and the top surface of the support base, and the bottom end of the bidirectional threaded column is connected to the top of the bevel gear II.

[0058] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0059] Figures 1 to 7 The diagram shown is a structural schematic of an embodiment of the downhole mapping positioning device of this utility model. The downhole mapping positioning device includes a support base 1.

[0060] Support side frame 2, the top of the support base 1 is connected to two support side frames 2;

[0061] Clamping plate 3, two clamping plates 3 are provided above the support base 1, and the two support side frames 2 are located between the two support side frames 2. The two clamping plates 3 are used to clamp the downhole surveying instrument.

[0062] The adjustment component 4 is connected to the opposite sides of the two clamping plates 3 respectively. The adjustment component 4 is installed inside the support side frame 2 and is used to control the position of the clamping plates 3.

[0063] Anti-slip component 5, which is connected to the support base 1, is released from the ground when the downhole surveying instrument is placed.

[0064] In this technical solution, the position adjustment component 4 can be used to adjust the position of the clamping plates 3 on both sides, thereby clamping and fixing the downhole mapping instrument using the clamping plates 3 on both sides. This prevents the downhole mapping instrument from shaking during mapping, which would affect the mapping accuracy and prevent the accuracy of downhole fixed-point mapping from being affected. At the same time, when installing the downhole mapping instrument, under the action of its gravity, the anti-slip component 5 automatically contacts the ground, increasing the friction between the device and the ground, thereby increasing the stability of the device. This allows the device to adapt to ground with a certain tilt angle, increasing the stability of the mapping instrument and expanding the adaptability range of the downhole mapping fixed-point device.

[0065] The adjustment component 4 includes a bidirectional threaded post 41, which is rotatably connected to the side of the support frame 2.

[0066] The surface of the bidirectional threaded column 41 is threadedly connected to two symmetrically distributed movable plates 42. Multiple adjusting columns 43 are provided on one side of the movable plates 42, and both ends of the adjusting columns 43 are rotatably connected to rotating frames 44.

[0067] One side of the rotating frame 44 is connected to one side of the moving plate 42, and the other side of the rotating frame 44 is connected to one side of the clamping plate 3.

[0068] In this technical solution, the position of the clamping plate 3 can be adjusted by the adjustment component 4, thereby realizing the clamping and releasing of the surveying instrument.

[0069] The inner wall of the support side frame 2 is connected to a plurality of anti-deviation shafts 45, and the surface of the anti-deviation shafts 45 is slidably connected to the movable plate 42.

[0070] In this technical solution, the movement trajectory of the moving plate 42 can be limited by the anti-deviation axis 45.

[0071] When in use, the drive component 6 rotates the fixed bidirectional threaded column 41, thereby driving the moving plates 42 on both sides to move towards or away from each other along the anti-deviation shaft 45. At this time, under the action of the rotating frame 44, the adjusting column 43 can rotate, thereby driving the clamping plate 3 to move.

[0072] The clamping plates 3 on both sides can move towards or away from each other, thereby clamping or releasing the surveying instrument, which facilitates the stable installation of the surveying instrument.

[0073] The anti-slip component 5 includes a placement platform 51, which is disposed above the support base 1, and a plurality of connecting columns 52 are connected to the bottom of the placement platform 51;

[0074] The surface of the connecting column 52 is slidably connected to the support base 1, and the bottom end of the connecting column 52 is connected to the top of the anti-slip plate 53;

[0075] The bottom of the placement platform 51 is connected to a plurality of elastic reset members 54, and the bottom end of the elastic reset members 54 is connected to the top of the support base 1.

[0076] In this technical solution, the anti-slip component 5 can increase the friction with the ground, thereby increasing the stability of the device.

[0077] When installing the surveying instrument, place it on the platform 51. Under the weight of the instrument, the connecting column 52 and the anti-slip plate 53 move downwards, causing the anti-slip plate 53 to press against the ground, thereby increasing the friction with the ground and increasing the stability of the positioning device. This, in turn, increases the stability of the surveying instrument during use and improves the accuracy of the surveying.

[0078] The bottom end of the bidirectional threaded post 41 is connected to the drive assembly 6;

[0079] The drive assembly 6 includes a bidirectional drive source 61, which is installed in the inner cavity of the support base 1. Both output ends of the bidirectional drive source 61 are connected to a drive shaft 62.

[0080] The drive shaft 62 is connected to a bevel gear 63, and a bevel gear 64 is meshed with the side of the bevel gear 63. The top of the bevel gear 64 is connected to the bottom of the bidirectional threaded column 41.

[0081] In this technical solution, the drive component 6 enables the bidirectional threaded columns 41 on both sides to rotate synchronously.

[0082] In use, the bidirectional drive source 61 drives the transmission shaft 62 to rotate, which in turn drives the first bevel gear 63 to rotate, and then drives the second bevel gear 64 to rotate, which in turn drives the bidirectional threaded column 41 to rotate.

[0083] The top end of the bidirectional threaded column 41 is rotatably connected to the top of the inner cavity of the support side frame 2, the bottom end of the bidirectional threaded column 41 is rotatably connected to the bottom surface of the support side frame 2 and the top surface of the support base 1, and the bottom end of the bidirectional threaded column 41 is connected to the top of the bevel gear 64.

[0084] The tops of both support side frames 2 are connected to auxiliary components 7, which include a fixed housing 71 connected to the tops of the support side frames 2.

[0085] Two extrusion plates 72 are slidably connected to the inner cavity of the fixed outer shell 71. Multiple fixing posts 73 are connected to the bottom of the extrusion plates 72. The bottom end of the fixing posts 73 is connected to the top of the clamping plate 3.

[0086] An airbag 74 is connected between the two extrusion plates 72, and a plurality of anti-slip stabilizing airbag strips 75 are connected to the side of the clamping plate 3 away from the adjustment component 4.

[0087] The retractable airbag bag 74 and the anti-slip stabilizing airbag strip 75 are connected by a connecting channel 76.

[0088] In this technical solution, the auxiliary component 7 can move along with the clamping plate 3, increasing the stability of the clamping plate 3 in clamping the surveying instrument.

[0089] The connecting channels 76 are respectively located inside the clamping plate 3, the fixing column 73 and the pressing plate 72.

[0090] In this technical solution, the connecting channel 76 can be used to connect the retractable airbag 74 and the anti-slip stabilizing airbag strip 75.

[0091] When the clamping plate 3 moves, it can drive the fixed column 73 to move in the same direction, thereby driving the extrusion plate 72 to move in the same direction. When the clamping plates 3 on both sides move towards each other, they can drive the extrusion plates 72 on both sides to move towards each other. The extrusion plates 72 on both sides are used to extrude and compress the airbag 74, and the extruded gas is sent into the anti-slip stabilizing airbag strip 75 through the connecting channel 76. The anti-slip stabilizing airbag strip 75 further increases the stability of the connection between the clamping plate 3 and the surveying instrument, and further improves the stability of the installation of the surveying instrument.

[0092] The top of the two supporting side frames 2 is connected to an arc-shaped top plate 8.

[0093] In this technical solution, the arc-shaped top plate 8 can be used to protect the support base 1 and surveying instruments.

[0094] The bottom of the support base 1 is connected to multiple casters 9.

[0095] In this technical solution, the movable wheel 9 facilitates the movement of the fixed-point device.

[0096] The bidirectional drive source 61 is a dual-axis motor or other device capable of outputting bidirectional rotational kinetic energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
