Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for three-dimensional laser mapping, specifically an auxiliary device for three-dimensional laser mapping. Background Technology

[0002] 3D laser mapping is an advanced measurement technology that uses lidar sensors to quickly and densely acquire non-contact 3D data of target objects. This technology is widely used in various fields, including geological exploration, topographic mapping, urban planning, and monitoring of buildings and industrial facilities. When performing 3D laser mapping operations, auxiliary devices are needed to stabilize the 3D laser mapping instrument. A support frame is one such auxiliary device used to provide stable support.

[0003] According to Chinese Patent Application No. 202211070731.4, a measurement auxiliary device for 3D laser scanner mapping is disclosed, including a storage module and a support module. The support module is fixedly connected to the scanner body. The storage module includes a storage box. One side of the bottom surface of the storage box is fixedly connected to the support module. Side rods are fixedly connected to the bottom of both sides of the storage box. Connecting rods are slidably connected to the inner side of the side rods. By sliding the connecting rods to the inner side of the side rods, the support module and the scanner body can be stored in the storage box. The storage box can be pulled by the connecting rods, and the connecting rods can be pulled out and rotated. The bottom of the support module is supported by the connecting rods and the storage box. The storage box used to store the scanner body can be used as an auxiliary support structure. The opening and closing of the connecting rods is convenient, which facilitates the mapping of the scanner body.

[0004] Existing technology effectively solves the problem that when using measurement auxiliary devices for 3D laser scanners, the auxiliary devices are relatively large in size in order to provide better support for the 3D laser scanner. This makes it inconvenient to unfold and retract the auxiliary devices, making the 3D laser scanner surveying more complicated. It has the advantages of conveniently supporting and storing the 3D laser scanner. However, the existing auxiliary support frame can rotate 360° during use, but it cannot adjust the angle, thus reducing the flexibility of using the 3D laser scanner.

This embodiment provides an auxiliary device for three-dimensional laser mapping, including a support assembly 1, a rotating assembly 2 mounted on the top of the support assembly 1, an adjusting assembly 3 mounted on the top of the rotating assembly 2, and a three-dimensional laser mapping instrument body 4 mounted on the top of the adjusting assembly 3. The support assembly 1 provides support, the rotating assembly 2 adjusts the direction of use, and the adjusting assembly 3 adjusts the angle of use. The adjusting assembly 3 includes a fixed plate 301, a movable plate 302, a second servo motor 303, a worm gear 304, a worm wheel 305, and a support plate 306. The movable plate 302 is located at... The top of the fixed plate 301 is fixed and movably connected to the fixed plate 301 via bearings. The second servo motor 303 is fixed to the surface of the fixed plate 301. The worm gear 305 is fixed to the bottom of the movable plate 302. The worm 304 is installed in the inner cavity of the fixed plate 301 and movably connected to the inner wall of the fixed plate 301 via bearings. The worm 304 meshes with the worm gear 305. The output shaft of the second servo motor 303 passes through the inner cavity of the fixed plate 301 and is connected to the worm 304 via transmission. The support plate 306 is fixed to the top of the movable plate 302. The three-dimensional laser mapping instrument body 4 is fixed to the top of the support plate 306.

[0024] like Figure 1-4 As shown, the 3D laser mapping instrument body 4 is used for 3D scanning. While providing support through the support component 1, it can also adjust the usage height. The rotating component 2 is used to drive the 3D laser mapping instrument body 4 to rotate, thereby adjusting the scanning direction to achieve 360° scanning. The output shaft of the second servo motor 303 rotates forward, driving the worm gear 304 to rotate. When the worm gear 304 rotates, it drives the movable plate 302 to flip to one end through the worm wheel 305. The movable plate 302 drives the support plate 306 to flip, thereby adjusting the usage angle of the 3D laser mapping instrument body 4. When the output shaft of the second servo motor 303 rotates in reverse, it causes the 3D laser mapping instrument body 4 to flip to the other end.

[0025] Example 2

The first bevel gear 204 meshes with the second bevel gear 205. The output shaft of the first servo motor 203 is connected to the first bevel gear 204. The first servo motor 203 is fixedly connected to the inner wall of the disk 201.

[0030] like Figure 3 and 4 As shown, the output shaft of the first servo motor 203 rotates, driving the first bevel gear 204 to rotate. When the first bevel gear 204 rotates, it drives the second bevel gear 205 to rotate. When the second bevel gear 205 rotates, it drives the fixed plate 301 to rotate through the transmission rod 202, thereby adjusting the scanning direction of the three-dimensional laser mapping instrument body 4 so that it can rotate and scan 360°.

The telescopic rod 101 adopts a telescopic structure, which can easily adjust the usage height, thereby meeting the needs of different users.

[0036] In use, the telescopic rod 101, the support leg 102, and the connecting plate 103 combine to form a tripod, which can stably support the 3D laser mapping instrument body 4. The telescopic rod 101 adopts a telescopic structure, which can easily adjust the usage height to meet the needs of different users. The output shaft of the first servo motor 203 rotates, which drives the first bevel gear 204 to rotate. When the first bevel gear 204 rotates, it drives the second bevel gear 205 to rotate.
