Description

Technical Field

[0001] This invention relates to the field of laser scanner technology, and more specifically to a low-deformation laser scanner support frame. Background Technology

[0002] 3D laser scanning technology, also known as real-scene replication technology, represents a technological revolution in surveying and mapping following GPS. This research focuses on: mathematical models of 3D vision measurement systems; the construction of universal 3D vision measurement systems; data fusion algorithms for redundant boundary 3D images; online pixel-level data registration of scanned image coordinates based on product motion tracking and adjacent image matching analysis algorithms; and sub-pixel accuracy visual calibration algorithms for 3D space. Currently, the support for fixing 3D laser scanners typically uses the tripods found on conventional surveying instruments. The 3D laser scanner is mounted vertically on the tripod. However, when measuring terrain in the field, the complex, uneven, and varying soil textures mean that accidentally kicking the tripod can easily cause it to shift, requiring the 3D laser scanner to be repositioned horizontally, thus affecting its measurement accuracy.

[0003] To address the aforementioned issues, invention patent CN 114923094 A discloses a support frame for 3D laser scanner measurements. This design incorporates a 3D laser scanner body and a support structure, with the support structure including several support legs and several walking mechanisms. Several support legs are evenly distributed along the lower surface of the 3D laser scanner body near its edge, and several telescopic tubes are installed in the center of the lower surface of the 3D laser scanner body. A walking mechanism is installed at one end of each telescopic tube, and adjacent walking mechanisms are connected by a second conveyor belt. This invention enables the 3D laser scanner to move automatically by switching on the motor. With guide wheels and walking wheels, the 3D laser scanner can move smoothly even on uneven surfaces, eliminating the need for re-leveling the scanner and improving measurement accuracy. Furthermore, it eliminates the need for manual carrying, making it convenient to use.

[0004] However, the above solution still has some shortcomings. Among them, the solution lacks buffering for the support structure. During use, when the device and scanning equipment are subjected to external airflow or ground vibration, the support structure is prone to deformation, which will affect the accuracy of the scanning data. Summary of the Invention

[0005] The present invention provides a low-deformation laser scanner support frame to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a low-deformation laser scanner support frame, including a mounting base;

[0012] A further improvement of the technical solution of the present invention is that the buffer mechanism further includes a buffer spring, which is disposed between the adjusting ring and the buffer rod, and the two ends of the buffer spring are fixedly connected to the adjusting ring and the buffer rod respectively.

[0013] A further improvement of the technical solution of the present invention is that: the protective mechanism includes a protective rod and a protective net, the protective rod is arranged around the edge of the support base, the protective rod is slidably connected to the support base, and the protective net is fixedly arranged between the protective rods.

[0014] A further improvement of the technical solution of the present invention is that the protective mechanism further includes a drive gear and a torsion spring. The drive gear is disposed inside the support base and is disposed adjacent to the protective rod. The protective rod has a toothed groove on its side that meshes with the drive gear. The torsion spring is fixedly disposed on the side of the drive gear.

[0015] A further improvement of the technical solution of the present invention is that the protective mechanism further includes a bracket and a limiting rod. The bracket is disposed at the bottom of the outer side of the buffer rod, the limiting rod is disposed inside the bracket, the top of the limiting rod abuts against the drive gear, and the limiting rod is a telescopic rod structure.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1

[0030] like Figure 1 , 2 As shown in Figures 3, 4, and 6, this invention provides a low-deformation laser scanner support frame, including a mounting base 1; the top of the mounting base 1 is provided with a mounting slot 2, and mounting bolts 3 are symmetrically provided at both ends of the mounting slot 2, the mounting bolts 3 passing through the mounting base 1; the bottom of the mounting base 1 is provided with a support mechanism 4, the bottom of the support mechanism 4 is provided with a buffer mechanism 5, and the support mechanism 4 is provided with a protective mechanism 6; the support mechanism 4 includes a support seat 401 and support legs 402, the support seat 401 is located at the bottom of the mounting base 1, the support seat 401 is rotatably connected to the mounting base 1, and there are three support legs 402, the three support legs 402 are symmetrically arranged on the side of the support seat 401, and the support legs 402 are rotatably connected to the support seat 401; the support mechanism 4 also includes an adjusting ring 403 and an adjusting bolt 404, the adjusting ring 403 is located inside the support leg 402, the adjusting bolt 404 is located on the side of the adjusting ring 403, the adjusting bolt 404 passes through the support leg 402 and is located on the outside of the support leg 402, and the side of the support leg 402 has a sliding groove corresponding to the structure of the adjusting bolt 404;

[0031] In this embodiment, the support mechanism 4 can support the support base 401 and the scanning device mounted on the top of the mounting base 1, while the adjustment structure can adjust the buffer mechanism 5 at the bottom, so that the device can adapt to the usage requirements of different heights.

[0032] Example 2

[0033] like Figure 1 , 2As shown in Figures 3 and 5, based on Embodiment 1, the present invention provides a technical solution: the buffer mechanism 5 includes a buffer rod 501 and a support leg 502. The buffer rod 501 is disposed at the inner end of the support leg 402, which has a hollow structure. The buffer rod 501 and the support leg 402 are slidably connected. The support leg 502 is disposed at the end of the buffer rod 501. The buffer mechanism 5 also includes a piston cylinder 503 and a piston rod 504. The piston cylinder 503 is disposed in the middle inside the support leg 402. The piston rod 504 is disposed inside the buffer rod 501 and inside the piston cylinder 503. The piston rod 504 and the piston cylinder 503 are slidably connected. The piston cylinder 503 has a balance air nozzle on its side. The buffer mechanism 5 also includes a buffer spring 505, which is disposed between the adjusting ring 403 and the buffer rod 501. The two ends of the buffer spring 505 are fixedly connected to the adjusting ring 403 and the buffer rod 501, respectively.

[0034] In this embodiment, the buffer mechanism 5 can buffer the device, thereby reducing the deformation of the support mechanism 4 caused by external airflow or ground vibration, which would affect the support of the scanning equipment.

[0035] Example 3

[0036] like Figure 1 , 2 As shown in Figure 4, based on Embodiment 1, the present invention provides a technical solution: the protective mechanism 6 includes a protective rod 601 and a protective net 602. The protective rod 601 is arranged around the edge of the support base 401, and the protective rod 601 is slidably connected to the support base 401. The protective net 602 is fixedly arranged between the protective rods 601. The protective mechanism 6 also includes a drive gear 603 and a torsion spring 604. The drive gear 603 is arranged inside the support base 401 and adjacent to the protective rod 601. The side of the protective rod 601 has a toothed groove that meshes with the drive gear 603. The torsion spring 604 is fixedly arranged on the side of the drive gear 603. The protective mechanism 6 also includes a bracket 605 and a limiting rod 606. The bracket 605 is arranged at the bottom of the outer side of the buffer rod 501. The limiting rod 606 is arranged inside the bracket 605. The top of the limiting rod 606 abuts against the drive gear 603. The limiting rod 606 is a telescopic rod structure.

[0037] In this embodiment, the protective mechanism 6 can protect the scanning device. When the device is subjected to a violent collision and there is a risk of it overturning, the protective rod 601 and the protective net 602 can automatically pop out and protect the scanning device, preventing the scanning device from being damaged by hitting the ground.

[0038] The working principle of this low-deformation laser scanner support frame will be explained in detail below.

[0039] like Figure 1-6As shown, during use, after moving the device to the set position, the scanning equipment is installed on the mounting base 1. The scanning equipment is then fixed by tightening the mounting bolts 3. Subsequently, the position of the adjusting ring 403 is adjusted using the adjusting bolts 404. During the movement of the adjusting ring 403, the buffer spring 505 at the bottom drives the buffer rod 501 for adjustment. After adjustment, the adjusting ring 403 is tightened using the adjusting bolts 404. Then, air is injected into the piston cylinder 503 through the balancing air nozzle, allowing the internal air pressure of the piston cylinder 503 to support the piston rod 504. During use, if the device is subjected to airflow or ground vibration causing the support mechanism 4 to deform... During operation, the piston cylinder 503 and the buffer spring 505 buffer the vibration, thereby improving the overall stability. When the device is overturned due to an accidental collision, one end of the support leg 502 is lifted due to the unstable center of gravity. At the same time, the buffer rod 501 moves outward under the air pressure inside the piston cylinder 503 and the elasticity of the buffer spring 505. As the buffer rod 501 moves, it drives the limit rod 606 to move synchronously. After the drive gear 603 loses the restraint of the limit rod 606, it rotates under the action of the energy-storing torsion spring 604 and drives the protective rod 601 to rise. The protective rod 601 and the protective net 602 then effectively protect the scanning equipment.
