AI Technical Summary
In the mapping of coal mining subsidence areas, conventional level instruments are difficult to place stably on soft and uneven ground, resulting in inaccurate angle adjustment. Manual calibration is difficult to quantify, often leading to excessive or substandard angles.
The level is adjusted by a motor. Through a rotating disk, rotating frame, and worm gear structure, the angle can be precisely adjusted by controlling the motor speed. The first motor and the second motor control the left and right tilt and pitch angles of the level, respectively.
It enables precise adjustment of the leveling instrument angle within coal mining subsidence areas, improving measurement accuracy and stability, and avoiding the unevenness and over-adjustment problems associated with manual adjustment.

[0030] Embodiment 1
[0031] Refer to Figs. 1-6 For the first embodiment of the utility model, a coal mining subsidence area surveying and mapping level gauge is provided, the level gauge comprises a measuring assembly 100 and a bottom assembly 200, wherein the measuring assembly 100 comprises a measuring instrument 101 and a rotating disc 102 arranged at the bottom of the measuring instrument 101; the bottom assembly 200 is arranged below the measuring instrument 101 and comprises a rotating frame 201, a mounting frame 202 rotatably connected with the rotating frame 201, a base 203 rotatably connected with the mounting frame 202, a worm gear 204 fixedly connected with the rotating frame 201, a worm 205 engaged with the worm gear 204, a first motor 206 and a second motor 207 arranged on the base 203.
[0032] The rotating disc 102 is rotatably connected with the rotating frame 201. The worm gear 204 is fixedly arranged in the rotating frame 201. The rotating shaft of the rotating frame 201 penetrates the mounting frame 202, and the worm gear 204 is arranged in the mounting frame 202. The mounting frame 202 is symmetrically provided with sleeves 202a on both sides, and the base 203 is symmetrically fixedly provided with mounting plates 203a. The sleeves 202a are rotatably connected with the mounting plates 203a. The worm 205 is rotatably arranged between the mounting plates 203a, and the worm 205 is arranged at the bottom of the worm gear 204. The first motor 206 and the second motor 207 are arranged on both sides of the mounting frame 202 respectively. The output shaft of the first motor 206 is fixedly connected with one sleeve 202a on the mounting frame 202. The output shaft of the second motor 207 is fixedly connected with the worm 205.
[0033] During use, after the surveying instrument 101 is placed in an inclined area, the base 203 is inclined due to the flat bottom surface, and the surveying instrument 101 on the base 203 is also inclined. When the angle of the surveying instrument 101 is adjusted, the rotating disc 102 can be manually rotated to make the surveying instrument 101 face the correct direction. When the left and right inclination amplitudes of the surveying instrument 101 need to be adjusted, the first motor 206 is started, and the output shaft of the first motor 206 can directly drive the rotation of one side of the sleeve 202a, the sleeve 202a is rotationally connected with the mounting plate 203a, thereby synchronously rotating the mounting frame 202. The forward and reverse rotation of the output shaft of the first motor 206 can make the mounting frame 202 left and right inclined. When the mounting frame 202 rotates, the rotating frame 201 is also synchronously inclined, and the worm gear 204 on the rotating frame 201 is inclined. Due to the self-locking of the worm gear 204 and the worm 205, the inclination of the worm gear 204 can drive the rotation of the worm 205. Therefore, when the second motor 207 is not working, the output shaft is not locked. When the pitch angle of the surveying instrument 101 needs to be adjusted, the second motor 207 is started, the output shaft of the second motor 207 can make the worm 205 rotate, the rotation of the worm 205 can make the worm gear 204 rotate, the worm gear 204 is fixed on the rotating frame 201, the rotating frame 201 and the mounting frame 202 are rotationally connected, the worm gear 204 can make the rotating frame 201 rise or lower on the mounting frame 202, thereby changing the pitch angle of the surveying instrument 101. During the modification of the pitch angle, the mounting frame 202 does not rotate, which can isolate the influence of the left and right inclination, and facilitate the calibration.
[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
