Description

Technical Field

[0001] This utility model relates to the field of mine surveying equipment technology, specifically a mine surveying and mapping instrument. Background Technology

[0002] Mines include coal mines, metal mines, non-metal mines, building material mines, and chemical mines, etc. Mine surveying is an important part of the mine construction and production phases. Because mine surveying involves both the surface and underground, it not only serves the mine's production and construction but also provides information for safety production, enabling leaders to make decisions on safety. Currently, the mine engineering surveying equipment available in the publicly available technology still has certain drawbacks in use. For example, traditional surveying equipment has poor stability and cannot maintain a perpendicular state to the ground when used on uneven surfaces, which can easily affect measurement accuracy.

[0003] For example, a mining surveying instrument disclosed in authorization announcement number CN219736377U includes: a mounting plate and a mounting mechanism; the mounting mechanism includes a support component and a mounting component, the support component for supporting the surveying instrument is mounted on the bottom of the mounting plate, and the mounting component for surveying mining projects is mounted on the top of the mounting plate; the support component includes multiple rotating shaft seats mounted on the outer surface of the mounting plate, a sleeve rod is rotatably mounted on the bottom of the rotating shaft seat, a return spring is fixedly mounted on the top of the inner cavity of the sleeve rod, a slide rod is fixedly mounted on the bottom end of the return spring, the bottom end of the slide rod passes through the sleeve rod and extends to the bottom of the sleeve rod, an anti-slip seat is rotatably mounted on the bottom of the slide rod via a rotating shaft, mounting seats are fixedly mounted on the bottom of both sides of the sleeve rod, a nut is fixedly mounted on one side of one mounting seat, a through hole is opened on the surface of the slide rod, a bolt is through mounted on one side of the other mounting seat, one end of the bolt passes through the sleeve rod, the sleeve rod and the through hole in sequence and is threadedly connected to the nut.

[0004] This mining surveying instrument, through the setting of a support component, allows operators to adjust the extension length of one or more sliding rods according to the tilt angle when placed on uneven ground. During adjustment, the bolt and nut are first rotated to separate them, allowing the bolt to be pulled out of the through hole and the inner cavity of the sleeve rod, thereby increasing or decreasing the extension length of the sliding rod. After the mounting component on the top of the mounting plate is placed horizontally, the bolt and nut are then connected. This facilitates the use of the instrument on uneven surfaces and avoids situations where tilting of the mounting component affects measurement accuracy.

[0005] As can be seen from the solutions disclosed in the existing patent documents, when adjusting the height of the surveying instrument by rotating the through hole of the screw threaded connection of the telescopic slide rod, the fixed position of the through hole limits the telescopic distance of the telescopic slide rod, making it impossible to make effective slight adjustments. This results in inaccurate height adjustment of the surveying instrument, affecting the measurement accuracy. Furthermore, it is inconvenient to make slight adjustments to the lateral position of the surveying instrument to ensure measurement accuracy. Therefore, it is necessary to improve the existing technology. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3The diagram shows a mining surveying and mapping instrument, including a support platform 1. The support platform 1 is equipped with a lateral adjustment mechanism for slight adjustment of the lateral position of the measuring equipment. The lateral adjustment mechanism includes a bearing 11 installed inside the support platform 1, a screw 12 inserted into the inner steel ring of the bearing 11, a cap 13 connected to one end of the screw 12, and a movable plate 14 threadedly connected to the outer side of the screw 12.

[0022] The upper end of the movable plate 14 is equipped with a longitudinal adjustment mechanism. The longitudinal adjustment mechanism is used to slightly adjust the longitudinal position of the measuring equipment. The longitudinal adjustment mechanism includes a bearing 15 installed inside the movable plate 14, a screw 16 inserted into the inner steel ring of the bearing 15, a rotating cover 17 connected to the upper end of the screw 16, and a bearing platform 18 threaded to the outer side of the screw 16. Guide rods 19 are provided on the upper surface of the movable plate 14.

[0023] A fixing mechanism is symmetrically arranged on the upper end face of the bearing platform 18. The fixing mechanism is used to fix the measuring equipment. A support mechanism is symmetrically arranged on the lower end face of the support platform 1. The support mechanism is used to support the surveying equipment.

[0024] Please see Figure 1 The internal sliding sleeve screw 12 of the support platform 1, and the internal sliding sleeve movable plate 14 of the support platform 1;

[0025] With this setup, rotating the screw 12 by rotating the toggle cap 13 causes the movable plate 14 and the measuring instrument 23 to move slowly laterally, effectively reducing measurement errors and improving the accuracy of measurement results. The design of the support platform 1 can guide the movable plate 14 to move laterally, preventing the movable plate 14 from deflecting laterally and affecting the measurement accuracy.

[0026] Please see Figure 1-2 The internal sliding sleeve of the support platform 18 is connected to the guide rod 19, and the upper end surface of the support platform 18 is in close contact with the surveying instrument 23;

[0027] In this configuration, rotating the rotating cover 17 drives the screw 16 to rotate, thereby causing the support platform 18 and the surveying instrument 23 to move slowly longitudinally to improve measurement accuracy. The guide rod 19 is designed to guide the support platform 18 to move longitudinally and prevent the support platform 18 from deviating to the side and affecting the measurement accuracy of the surveying instrument 23.

[0028] Please see Figure 1 The fixing mechanism includes a baffle 2 symmetrically arranged on the upper end of the support platform 18, a threaded bolt 21 connected inside the baffle 2, a pressure plate 22 connected to one end of the bolt 21, a surveying instrument 23 pressed on one side of the pressure plate 22, and a level 24 set on the upper end of the surveying instrument 23.

[0029] With this setup, rotating the tightening bolt 21 drives the pressure plate 22 to press the measuring instrument 23, which facilitates the fixed installation of the measuring instrument 23. When the level 24 is tilted, the liquid level is different, and the bubble will move to the tilt direction to indicate the degree of offset of the level 24. The operator can adjust the height and tilt of the support leg 34 according to the level 24, thereby adjusting the horizontal position of the measuring instrument 23.

[0030] Please see Figure 1 and Figure 3 The support mechanism includes a shaft support 3 provided on the lower end face of the support platform 1, a screw 31 connected to the internal thread of the shaft support 3, a support cylinder 32 slidably connected inside the shaft support 3, an adjusting screw 33 connected to the internal thread of the support cylinder 32, a support leg 34 slidably inserted inside the support cylinder 32, one end of the screw 31 pressing against the rotating shaft at the upper end of the support cylinder 32, and one end of the adjusting screw 33 pressing against the support leg 34.

[0031] With this setup, by rotating the support cylinder 32 and extending and retracting the support leg 34, and by rotating the tightening screw 31 and adjusting screw 33, the tilt of the support platform 1 can be easily adjusted so as to horizontally support the surveying instrument 23 on uneven and sloping mountainous terrain, thereby improving measurement accuracy.

[0032] The working principle of this embodiment is as follows: When using this mining surveying instrument, by rotating the support cylinder 32 and extending and retracting the support leg 34, and rotating the tightening screw 31 and adjusting screw 33, the inclination of the support platform 1 can be easily adjusted so as to horizontally support the surveying instrument 23 on uneven and sloping mountainous terrain, thereby improving the measurement accuracy.

[0033] Rotating the tightening bolt 21 drives the pressure plate 22 to press the measuring instrument 23, which facilitates the fixed installation of the measuring instrument 23. When the level 24 is tilted, the liquid level is different, and the bubble will move to the tilt direction to indicate the degree of offset of the level 24. The operator can adjust the height and tilt of the support leg 34 according to the level 24, thereby adjusting the horizontal position of the measuring instrument 23.

[0034] By rotating the screw cap 13, the screw 12 is rotated, which in turn drives the movable plate 14 and the surveying instrument 23 to move slowly laterally, effectively reducing measurement errors and improving the accuracy of measurement results.

[0035] It should be noted that the design of the support platform 1 can guide the lateral movement of the movable plate 14, preventing the lateral deviation of the movable plate 14 from affecting the measurement accuracy.

[0036] Rotating the rotating cover 17 drives the screw 16 to rotate, thereby causing the support platform 18 and the surveying instrument 23 to move slowly longitudinally in order to improve measurement accuracy;

[0037] It is worth noting that the guide rod 19 is designed to guide the longitudinal movement of the support platform 18, preventing the support platform 18 from deviating to the side and affecting the measurement accuracy of the surveying instrument 23.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
