Description

Technical Field

[0001] This utility model relates to the field of mine surveying technology, specifically a multi-distance measuring device for mine surveying. Background Technology

[0002] Mine surveying is an important applied discipline in mining engineering. It mainly studies spatial positioning, data acquisition, information processing, and engineering layout technologies in the mine development process. It is a key link in ensuring safe production, rational resource development, and efficient operation of mines.

[0003] Existing patent CN215810850U provides a shake-prevention device for a rangefinder used in mine surveying. It uses matching protrusions and slots on the bottom of the rangefinder and the surface of the support to fix it in place, making the connection tighter and more stable, which can effectively prevent shaking. However, the rigid structure lacks a buffer mechanism, resulting in poor shake-prevention effect. In view of this, a multi-rangefinder device for mine surveying is proposed. Utility Model Content

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a multi-distance measuring device for mine surveying, which has the following beneficial effects:

[0021] 1. This multi-distance measuring device for mine surveying transmits the swaying of the mounting plate to the moving block via the support rod, causing it to slide in the first groove and compress or stretch the second spring. The spring elasticity provides initial buffering. At the same time, the hydraulic damper on the lower surface of the mounting plate is sleeved on the sliding roller of the base plate, which consumes vibration energy through liquid resistance to suppress high-frequency swaying. The first spring between the base plate and the mounting plate further assists in buffering, ensuring that the distance measuring device on the mounting plate remains stable in the complex environment of the mine and improving measurement accuracy.

[0022] 2. This multi-distance measuring device for mine surveying uses a motor to drive a worm gear to rotate, which meshes with a worm wheel to drive a coaxial transmission roller to rotate. This causes the disc at the upper end of the transmission roller to rotate synchronously. The first support rod on its outer surface makes a circular motion, and then pushes the C-shaped clamping plate to slide in the second slide groove through the second support rod. Because the second support rod is rotatably connected to the C-shaped clamping plate, the circular motion is converted into linear sliding, so that the two C-shaped clamping plates move closer or further apart synchronously. This allows for quick clamping or loosening of distance measuring devices of different specifications, simplifies the installation process, and enhances the versatility of the equipment.

[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a new technical solution: a multi-distance measuring device for mine surveying, including a base plate 1, and four first sliding grooves 5 are formed on the upper surface of the base plate 1;

[0030] The base plate 1 is equipped with an anti-shaking mechanism, which includes a sliding roller 2, a hydraulic damper 3, a first spring 4, a second spring 6, a moving block 7, a support rod 8, a mounting plate 9, a second slide groove 10, a motor 11, a worm gear 12, a worm wheel 13, a transmission roller 14, a disc 15, a first support rod 16, a second support rod 17, and a C-shaped clamping plate 18.

[0031] Furthermore, four first springs 4 are fixedly installed in the inner walls of four first slide grooves 5, and four moving blocks 7 are fixedly installed at the opposite ends of the four first springs 4, and the four moving blocks 7 are slidably sleeved in the inner walls of the four first slide grooves 5.

[0032] Furthermore, the four support rods 8 are rotatably connected to the upper surfaces of the four movable blocks 7, and the mounting plates 9 are rotatably connected to the upper ends of the four support rods 8.

[0033] Two second grooves 10 are formed on the upper surface of the mounting plate 9.

[0034] Furthermore, the sliding roller 2 is fixedly installed on the upper surface of the base plate 1, the hydraulic damper 3 is slidably sleeved on the outer surface of the sliding roller 2, and the hydraulic damper 3 is fixedly installed on the lower surface of the mounting plate 9.

[0035] Furthermore, the first spring 4 is fixedly installed on the upper surface of the base plate 1, and the upper end of the first spring 4 is fixedly installed on the lower surface of the mounting plate 9.

[0036] Furthermore, the motor 11 is fixedly installed in the inner wall of the mounting plate 9, and the worm gear 12 is fixedly installed at the output end of the motor 11.

[0037] Furthermore, the worm gear 13 is meshed with the outer surface of the worm 12, and the transmission roller 14 is fixedly sleeved on the inner surface of the worm gear 13. The lower end of the transmission roller 14 is rotatably connected to the inner wall of the mounting plate 9.

[0038] Furthermore, the disc 15 is fixedly mounted on the upper end of the transmission roller 14, and the two first support rods 16 are fixedly mounted on the outer surface of the disc 15.

[0039] Furthermore, the two second support rods 17 are rotatably connected to the upper ends of the two first support rods 16 respectively.

[0040] Furthermore, the two C-shaped clamps 18 are rotatably connected to the upper ends of the two second support rods 17, and the two C-shaped clamps 18 are slidably connected to the two second sliding grooves 10.

[0041] This multi-distance measuring device for mine surveying causes the mounting plate 9 to vibrate up and down or tilt when the device vibrates due to ground bumps in the mine. The vibration of the mounting plate 9 is transmitted to the moving block 7 through the support rod 8, causing the moving block 7 to slide within the first groove 5, compressing or stretching the second spring 6. The spring elasticity buffers the vibration. At the same time, the lower surface of the mounting plate 9 is fitted onto the sliding roller 2 of the base plate 1 through a hydraulic damper 3. The hydraulic damper consumes vibration energy through fluid resistance, suppressing high-frequency shaking. The first spring 4 between the base plate 1 and the mounting plate 9 further assists in buffering, forming a double protection system in conjunction with the hydraulic damper. The shaking effect ensures the stability of the ranging device on the mounting plate 9. The motor 11 starts, driving the worm gear 12 to rotate. The worm gear meshes with the worm wheel 13, driving the worm wheel and the coaxial transmission roller 14 to rotate. The disc 15 at the upper end of the transmission roller 14 rotates accordingly, driving the first support rod 16 on its outer surface to make a circular motion. The first support rod 16 pushes the C-shaped clamp 18 to slide in the second slide groove 10 through the second support rod 17. Because the second support rod is rotatably connected to the C-shaped clamp, the circular motion is converted into linear sliding. The two C-shaped clamps 18 move closer or further away at the same time, realizing the clamping or loosening of the ranging device, which facilitates the quick fixation of devices of different specifications.

[0042] This multi-distance measuring device for mine surveying transmits the swaying of the mounting plate 9 to the moving block 7 via the support rod 8. This causes the moving block 7 to slide within the first groove 5 and compress or stretch the second spring 6, utilizing the spring's elasticity for initial buffering. Simultaneously, a hydraulic damper 3 on the lower surface of the mounting plate 9 is fitted onto the sliding roller 2 of the base plate 1, consuming vibration energy through liquid resistance to suppress high-frequency swaying. The first spring 4 between the base plate 1 and the mounting plate 9 further assists in buffering, ensuring the stability of the distance measuring equipment on the mounting plate 9 in the complex environment of a mine, thus improving measurement accuracy. The multi-range measuring device uses a motor 11 to drive a worm gear 12 to rotate, which meshes with a worm wheel 13 and drives a coaxial transmission roller 14 to rotate. This causes the disk 15 at the upper end of the transmission roller 14 to rotate synchronously. The first support rod 16 on its outer surface makes a circular motion, and then pushes the C-shaped clamping plate 18 to slide in the second slide groove 10 through the second support rod 17. Because the second support rod is rotatably connected to the C-shaped clamping plate, the circular motion is converted into linear sliding, so that the two C-shaped clamping plates 18 can move closer or further apart synchronously. This allows for the quick clamping or loosening of ranging devices of different specifications, simplifies the installation process, and enhances the versatility of the equipment.

[0043] Structural Description:

[0044] Base plate 1: As the basic load-bearing component of the entire device, it provides an installation platform for other components. The four first sliding grooves 5 on it are the sliding tracks of the moving block 7. By supporting the sliding roller 2, the first spring 4 and other components, the various parts of the device are integrated into a whole, ensuring the stability of the overall structure.

[0045] Sliding roller 2: Fixed on the upper surface of the base plate 1, providing sliding support for the hydraulic damper 3. The hydraulic damper 3 slides on its outer surface, and works with the hydraulic damper 3 to buffer the shaking of the mounting plate 9, thereby enhancing the device's anti-shaking performance and reducing the impact of vibration in the complex mining environment.

[0046] Hydraulic damper 3: It slides on the outer surface of the sliding roller 2, with its lower end connected to the base plate 1 and its upper end connected to the mounting plate 9. Utilizing the hydraulic damping characteristics, it reduces the up-and-down swaying of the mounting plate 9 caused by vibration. Together with other anti-vibration components, it improves the stability of the device and ensures measurement accuracy.

[0047] First spring 4: Partially connects the base plate 1 and the mounting plate 9. It absorbs vibration energy through elastic deformation, buffers the shaking of the mounting plate 9, assists the moving block 7 in resetting, and enhances the anti-shaking effect.

[0048] First groove 5: It is opened on the base plate 1 and is the sliding channel of the moving block 7. It restricts the movement trajectory of the moving block 7 and makes it slide stably along the groove. Together with the first spring 4 and the moving block 7, it realizes elastic support and buffering for the mounting plate 9.

[0049] Movable block 7: It is fitted into the first slide groove 5, connected to the first spring 4 and the support rod 8. It slides under the elastic force of the first spring 4 and transmits force through the rotating support rod 8 to adjust the height and angle of the mounting plate 9, buffer vibration, and maintain the stability of the mounting plate 9.

[0050] Support rod 8: The lower end is connected to the moving block 7, and the upper end is connected to the mounting plate 9 to form a support structure. The sliding of the moving block 7 is converted into the angle and height adjustment of the mounting plate 9. With the help of springs and dampers, the force on the mounting plate 9 is balanced, and the anti-shaking ability is enhanced.

[0051] Mounting plate 9: Connected to moving block 7 via support rod 8, it supports components such as motor 11. The second slide groove 10 provided by the plate provides a sliding track for C-shaped clamp 18, serving as an intermediate carrier to coordinate the work of the upper and lower components and ensure the stable installation of the ranging equipment.

[0052] The second slide groove 10 is formed on the mounting plate 9, allowing the C-shaped clamp 18 to slide, restricting the movement direction of the C-shaped clamp 18, so that it can move smoothly along the slide groove, making it easy to adjust the distance between the two C-shaped clamps 18, and adapting to the fixing requirements of distance measuring equipment of different sizes.

[0053] Motor 11: Fixed to the inner wall of mounting plate 9, with its output end connected to worm gear 12, serving as a power source. By operating, it drives worm gear 12 to rotate, thereby driving worm wheel 13 and other components to work together to achieve position adjustment of C-shaped clamp 18 and provide power for equipment fixation.

[0054] Worm 12: Fixed at the output end of motor 11, meshing with worm wheel 13, transmitting the rotational power of motor 11 to worm wheel 13, changing the direction of power transmission, and driving subsequent components to operate through meshing with worm wheel 13, thus realizing power conversion and transmission.

[0055] Worm gear 13 meshes with worm 12 and has an inner drive roller 14. It rotates under the drive of worm 12, converting the horizontal rotation of worm 12 into the vertical rotation of itself and drive roller 14, realizing power transmission, driving disk 15 to rotate, and providing power for the movement of C-shaped clamp 18.

[0056] Transmission roller 14: The lower end is connected to the mounting plate 9, the upper end is connected to the disc 15, and the outer sleeve is a worm gear 13. It rotates under the drive of the worm gear 13, and transmits the rotational motion of the worm gear 13 to the disc 15. As a transmission component connecting the worm gear 13 and the disc 15, it ensures effective power transmission.

[0057] Disc 15: Fixed to the upper end of transmission roller 14, connected to two first support rods 16. As the transmission roller 14 rotates, it drives the first support rods 16 to make circular motion, converting the rotational motion into the swing of the first support rods 16, providing power for the second support rod 17.

[0058] First support rod 16: fixed on the outer surface of disk 15, with the upper end connected to second support rod 17. It swings with the rotation of disk 15, converting the rotational motion of disk 15 into the pushing and pulling motion of second support rod 17, thereby driving C-shaped clamp 18 to slide in second slide groove 10.

[0059] The second support rod 17 is connected to the first support rod 16 at its lower end and to the C-shaped clamp 18 at its upper end. It transmits the power of the first support rod 16 and pushes the C-shaped clamp 18 to slide in the second slide groove 10. It adapts to the angle change by rotating itself to ensure that the C-shaped clamp 18 moves smoothly.

[0060] C-shaped clamp 18: It is slidably connected to the second slide groove 10 and connected to the first support rod 16 through the second support rod 17. It moves along the second slide groove 10 under the push of the second support rod 17. The two C-shaped clamps 18 cooperate with each other to clamp and fix the ranging device to prevent it from shaking during measurement.

[0061] 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.
