[0002] The stabilization device of 3D laser point cloud mapping equipment is a device used to ensure that the 3D laser point cloud mapping equipment maintains stability during operation. By integrating high-precision sensors, automatic adjustment mechanisms and stability control systems, it monitors the equipment posture in real time and automatically adjusts it, effectively offsetting external environmental interference and the equipment's own vibration, thereby ensuring the accuracy and reliability of the mapping data.

[0003] In the field of 3D laser point cloud mapping, traditional equipment is usually fixed to a table or installed on a lifting device through bolts to expand the mapping range. However, the bolt fixing method has the problems of inconvenient disassembly and assembly and low efficiency, while the lifting device installation method has a limited mapping range due to the lack of angle adjustment capability. In addition, both lack an effective seismic structure, making the equipment unstable during use and susceptible to external vibrations. At the same time, there is a lack of effective protection for the equipment, which in turn affects the accuracy of the mapping data and the service life of the equipment. Therefore, improvement is needed. Utility Model Content

The present invention aims to solve the problem raised in the above background that in the field of three-dimensional laser point cloud mapping, traditional equipment is usually fixed to a table or installed on a lifting device by bolts to expand the mapping range, but the bolt fixing method has the problems of inconvenient disassembly and assembly and low efficiency, and the lifting equipment installation method has a limited mapping range due to the lack of angle adjustment capability, and both lack an effective seismic structure, which makes the equipment unstable during use and easily affected by external vibrations.

The bottoms of the first L-shaped support rod, the second L-shaped support rod, and the third L-shaped support rod are respectively sleeved with a sixth gear, a seventh gear, and an eighth gear via a connecting rod. The sixth gear, the seventh gear, and the eighth gear enable the first curved rod, the second curved rod, and the third curved rod to adjust the angle of the surveying and mapping equipment through a second drive assembly.

[0009] The damping mechanism is installed in the middle of the first L-shaped support rod, the second L-shaped support rod and the third L-shaped support rod in the multi-angle adjustment mechanism, and is used to maintain the stability of the equipment.

[0010] Preferably, the linkage assembly includes a third rotating shaft rotating inside the third fixed plate, and the outer side of the third rotating shaft is fixedly provided with a first gear and a second gear.

[0019] The beneficial effects of the present invention are:

[0020] The present invention effectively avoids the problems of inconvenient assembly and disassembly and low efficiency of traditional bolt fixing methods by setting a positioning and rotating mechanism. When the three-dimensional laser point cloud surveying and mapping equipment is fixed and installed, the second motor drives the second rotating shaft to rotate, so that the threaded blades on the outer side of the second rotating shaft drive the second gear in the linkage assembly to rotate synchronously, and then, under the connection of the third rotating shaft, the first gear is located on the outer side of the step cylinder to engage and transmit up and down. At this time, the step cylinder will drive the third gear provided inside the positioning platform to rotate, and then the bidirectional screw can enable the positioning seat to clamp and position the surveying and mapping equipment under the rotation of the third gear, so as to solve the inconvenience caused by bolt fixing. When adjusting the horizontal angle of the three-dimensional laser point cloud surveying and mapping equipment, the first motor drives the fifth gear to engage and transmit with the fourth gear, driving the first rotating shaft to rotate and the positioning platform to rotate synchronously, so as to change the horizontal angle adjustment of the surveying and mapping equipment, thereby effectively improving the stability of the equipment and the accuracy of the surveying and mapping data.

[0021] The present invention effectively avoids the problems of single angle adjustment and limited surveying range of traditional lifting equipment by setting a multi-angle adjustment mechanism. When performing three-dimensional angle surveying and adjustment of the surveying and mapping equipment, the third motor, the fourth motor and the fifth motor respectively drive the ninth gear, the tenth gear and the eleventh gear to respectively drive the sixth gear, the seventh gear and the eighth gear to rotate, so that the connecting rod pushes the first L-shaped support rod, the second L-shaped support rod and the third L-shaped support rod to rotate around the bottom of the support arm, and then the spatial posture of the support arm is adjusted by the linkage of the first curved rod, the second curved rod and the third curved rod. By driving one of the third motor, the fourth motor and the fifth motor separately, the spatial posture of the relative position can be changed accordingly. For example, when the third motor rotates forward, the sixth gear drives the first L-shaped support rod to lift upward, so that the first curved rod pushes the support arm forward. At the same time, adjusting the angles of the other two support rods can realize lateral deflection or pitching compound action, so that the surveying instrument can scan in all directions, eliminating the detection blind spots of traditional upright equipment.

[0022] The present invention effectively avoids the problems of data distortion and component wear caused by the lack of shock resistance of traditional equipment by setting up a damping mechanism. When in use, the damping mechanism slides in the air cavity through the push rod and piston at the bottom of the shock-absorbing top plate. When external vibration is transmitted to the damping frame, the piston compresses the air in the air cavity, and the gas slowly releases energy through the air outlet to achieve vibration attenuation. At the same time, the damping spring between the extrusion plate and the damping frame further absorbs the impact energy, thereby effectively improving data accuracy and equipment service life.

When adjusting the horizontal angle of the three-dimensional laser point cloud surveying and mapping equipment, the fifth gear is driven by the first motor to engage with the fourth gear for transmission, driving the first rotating shaft to rotate and the positioning platform to rotate synchronously, thereby changing the horizontal angle adjustment of the surveying and mapping equipment.

[0036] The multi-angle adjustment mechanism 3 is installed at the bottom of the support arm 201 in the positioning and rotating mechanism 2, and is used to realize three-dimensional angle adjustment of the surveying and mapping equipment. The multi-angle adjustment mechanism 3 includes a first curved rod 301, a second curved rod 302 and a third curved rod 303 that are arranged on the outside of the support arm 201 in a circular rotation. The bottoms of the first curved rod 301, the second curved rod 302 and the third curved rod 303 are respectively rotatably provided with a first L-shaped support rod 304, a second L-shaped support rod 305 and a third L-shaped support rod 306.

A push rod 405 and an extrusion plate 407 are fixedly provided at the bottom of the shock-absorbing top plate 404. The push rod 405 is movably arranged inside the air cavity 402 through a piston 406. A damping spring 408 is symmetrically fixed between the extrusion plate 407 and the damping frame 401. The damping mechanism slides in the air cavity through the push rod and the piston at the bottom of the shock-absorbing top plate. When external vibration is transmitted to the damping frame, the piston compresses the air in the air cavity, and the gas slowly releases energy through the air outlet to achieve vibration attenuation.

A mounting base 317 is installed on the outside of the second drive assembly. When the third motor rotates forward, the sixth gear drives the first L-shaped support rod to lift upward, causing the first curved rod to push the support arm forward. Simultaneously, adjusting the angles of the other two support rods can achieve lateral deflection or pitch compound action, enabling the surveying instrument to scan in all directions.

[0041] Working principle: The positioning and rotating mechanism 2 is fixed by the first fixed plate 203, the second fixed plate 204 and the third fixed plate 205 through the support arm 201, providing stable support for the entire device. Inside the second fixed seat 204, the first rotating shaft 205 and the second rotating shaft 207 are respectively rotated, wherein the outer side of the first rotating shaft 205 is movably connected to the step cylinder 206, and the outer side of the second rotating shaft 207 is fixedly connected to the spiral blade 208. The two rotating shafts are synchronized by a linkage assembly. The linkage assembly includes a third rotating shaft 209 located inside the third fixed plate 204, and a first gear 210 and a second gear 211 fixed to the outer side of the third rotating shaft 209. A clamping mechanism is provided inside the positioning platform 221, which includes a meshing transmission on the platform. The third gear 212 on the outside of the step cylinder 206 and the bidirectional screw 213 rotatably arranged inside the positioning platform 221 are fixedly arranged between the third gear 212 and the bidirectional screw 213, and the bidirectional screw 213 is symmetrically threaded with a positioning seat 214 on the outside, which is used to clamp the surveying instrument 1 to ensure its stability during installation. In order to further improve the fixing effect, the positioning seat 214 is fixedly provided with an anti-slip bump 215 and a positioning block 216 at one end corresponding to the surveying instrument 1. The rotation of the first rotating shaft 205 and the second rotating shaft 207 is controlled by a first driving assembly, which includes a first motor 219 and a second motor 220. The second motor 220 drives the second rotating shaft 207 to rotate, thereby driving the spiral blade 208 and the second gear 21 in the linkage assembly. 1 rotates synchronously, and through the transmission of the third rotating shaft 209, the first gear 210 engages and transmits with the step cylinder 206 to realize the telescopic action of the step cylinder. At the same time, the first motor 219 drives the fifth gear 218 to engage and transmit with the fourth gear 217, driving the first rotating shaft 205 and the positioning platform to rotate synchronously, thereby realizing the horizontal angle adjustment of the surveying and mapping equipment. The multi-angle adjustment mechanism 3 is installed at the bottom of the support arm 201, including a first curved rod 301, a second curved rod 302 and a third curved rod 303. These curved rods are arranged to rotate in a circular manner. The bottom of each curved rod is respectively rotatably provided with a first L-shaped support rod 304, a second L-shaped support rod 305 and a third L-shaped support rod 306. The bottom of these L-shaped support rods is sleeved with a sixth gear 308 and a seventh gear 309 through a connecting rod 307. 09 and the eighth gear 310, the second drive assembly includes a third motor 314, a fourth motor 315 and a fifth motor 316, as well as corresponding ninth gear 311, tenth gear 312 and eleventh gear 313. These motors drive the gears to rotate, pushing the connecting rod to rotate the L-shaped support rod around the bottom of the support arm. The spatial posture of the support arm is adjusted through the linkage of the curved rod. Driving any motor alone can change the spatial posture of the relative position, thereby realizing three-dimensional angle adjustment of the surveying and mapping equipment. For example, when the third motor rotates forward, the sixth gear drives the first L-shaped support rod to lift upward, causing the first curved rod to push the support arm forward. At the same time, adjusting the angles of the other two rods can realize lateral deflection or pitch compound action, so that the surveying and mapping instrument can scan in all directions. The damping mechanism 4 is installed in the middle of the L-shaped support rod.It includes a damping frame 401, an air cavity 402, an air outlet 403, a shock-absorbing top plate 404, a push rod 405, an extrusion plate 407, and a piston 406. When external vibrations are transmitted to the damping frame, the piston 406 compresses the air in the air cavity 402. The air slowly releases energy through the air outlet 403, achieving vibration attenuation. At the same time, the damping spring between the extrusion plate 407 and the damping frame 401 further absorbs impact energy, providing additional shock absorption. In summary, this stabilization device achieves fixed and horizontal rotation adjustment of the surveying and mapping equipment through a positioning and rotation mechanism, and achieves three-dimensional angle adjustment of the surveying and mapping equipment through a multi-angle adjustment mechanism. The damping mechanism effectively attenuates external vibrations, ensuring the stability and accuracy of the surveying and mapping equipment in complex environments.
