[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] like Figure 1 As shown, the present application provides a laser radar point cloud data acquisition device for surveying and mapping, including a support assembly 10 and a shock-absorbing assembly 20 fixedly mounted on the support assembly 10, a surveying instrument 30 being fixedly mounted on one end of the shock-absorbing assembly 20, wherein the support assembly 10 is capable of contacting the ground, and the support assembly 10 is used to support the whole, while the shock-absorbing assembly 20 is used to absorb shock for the surveying instrument 30 and can place the surveying instrument 30, and finally the surveying instrument 30 is used for surveying and mapping and terrain analysis.

[0031] like Figure 1As shown, the support assembly 10 includes a base 11, and the bottom of the base 11 is hinged with several groups of support legs 12, and the several groups of support legs 12 can respectively contact the ground. At the same time, the base 11 is used for stabilization and weighting, thereby increasing the overall stability of the equipment, and the support legs 12 provide stable support after contacting the ground. The support legs 12 can be made of lightweight and high-strength materials such as aluminum alloy or carbon fiber to ensure stability and reduce weight. At the same time, the bottom of the several groups of support legs 12 is fixedly installed with foot pads (not shown in the figure), which can be rubber, silicone or other shock-absorbing materials to increase friction and reduce the transmission of ground vibration.

[0032] like Figure 4 As shown, a support rod 13 is fixedly installed at the bottom of the base 11, and a limit rod 14 is hingedly connected to the support leg 12 close to the support rod 13, and a fixed module 15 is slidably connected to the support rod 13. The fixed module 15 can be hinged to the limit rod 14, so that the support leg 12 can further improve the supporting effect of the support leg 12 through the cooperation between the fixed module 15 and the limit rod 14 when it is unfolded.

[0033] When the fixed module 15 is in use, the fixed module 15 includes a fixed ring 151, which is slidably connected to the support rod 13. The limit rod 14 is located on the outside of the fixed ring 151. At the same time, a sleeve rod 153 is fixedly installed on the fixed ring 151. The sleeve rod 153 consists of two parts that are socketed with each other. At the same time, a spring 154 is provided inside the sleeve rod 153, so that the sleeve rod 153 can be extended and retracted by the spring 154.

[0034] In addition, two groups of fixing holes 152 distributed upper and lower are provided on the support rod 13, and the fixing holes 152 are adapted to the ends of the sleeve rod 153. At the same time, the sleeve rod 153 can pass through the fixing ring 151 and contact and combine with the fixing holes 152, so that when the support leg 12 is unfolded outward, the limit rod 14 will drive the fixing ring 151 to move on the support rod 13. When the support leg 12 is fully unfolded, the sleeve rod 153 will be aligned with the fixing hole 152 in the lower part. The spring 154 will make the sleeve rod 153 enter the interior of the fixing hole 152 in the lower part, so that the limit rod 14 can support the bottom of the support leg 12, thereby further improving the supporting effect of the support leg 12.

[0035] When the support leg 12 is recovered, the sleeve rod 153 can be pulled outward, so that the sleeve rod 153 will be disengaged from the fixing hole 152 in the lower part, and the support leg 12 will drive the limit rod 14 to reset on the support rod 13, and then the fixing ring 151 will gradually approach the fixing hole 152 in the upper part, and the sleeve rod 153 will enter the fixing hole 152 in the upper part, so that the support leg 12 can be fixed after recovery and shaking can be avoided.

[0036] like Figure 2 and Figure 3 As shown, the shock absorbing assembly 20 includes a support seat 21, which is fixedly mounted on the base 11, and a bracket a23 and a bracket b24 are movably mounted on the support seat 21, which are distributed up and down. A damper 25 is movably mounted between the bracket a23 and the bracket b24, and a connecting rod 22 is movably mounted at the ends of the bracket a23 and the bracket b24. When the equipment encounters external instability, the damper 25 will absorb the impact force, and the damper 25 will restore the bracket a23 and the bracket b24 to their original state after the impact force disappears, thereby reducing the vibration of the equipment.

[0037] A fixed block 26 is fixedly mounted on one end of the connecting rod 22, and a rotating shaft 27 is fixedly mounted on the fixed block 26. The fixed block 26 is used to support and place the rotating shaft 27 and the surveying instrument 30. At the same time, the rotating shaft 27 can adjust the angle of the surveying instrument 30, so that the surveying instrument 30 can scan the environment from different angles.

[0038] At the same time, protrusions (not shown) are fixedly installed at both ends of the rotating shaft 27, and bolts 29 are provided on the protrusions. A threaded hole is opened on the surveying instrument 30 near the bolts 29, so that the bolts 29 are passed through the protrusions and connected with the threads, so that the surveying instrument 30 can be smoothly installed on the rotating shaft 27 and conveniently disassembled.

[0039] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
