Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional laser radar scanners, in particular to a ground-mounted three-dimensional laser radar scanner positioning structure. Background Art

[0002] A 3D LiDAR scanner is a high-precision sensor device used to generate 3D point cloud data of the environment. It measures the distance and shape of the surrounding environment by emitting laser pulses and receiving the reflected signals, thereby creating an accurate 3D model of objects, terrain or buildings.

[0003] At present, when scanning large buildings, ground-mounted 3D LiDAR scanners usually set up multiple scanning points for comprehensive scanning. When changing the scanning points, the LiDAR scanner needs to be moved. The 3D LiDAR scanner has a motor-driven rotating device. When moving after power failure, the rotating device loses motor braking, and the LiDAR scanner rotates under the action of gravity during the movement. This rotation can easily cause damage to the rotating device, and when changing the scanning points during movement, the LiDAR scanner is exposed to the outside, which can easily cause the LiDAR scanner to bump into and damage the LiDAR scanner.

Through the handles 9, people can conveniently lift the protective cover 5, which is convenient for installation and removal of the protective cover 5, and both sides of the bottom of the protective cover 5 are provided with card slots 6 that match the mounting plate 4, and two buckles 10 are fixedly installed on the side of the lower end of the protective cover 5, and the two buckles 10 are symmetrically arranged, and hooks 11 are fixedly installed on the sides of both ends of the mounting plate 4, and the two hooks 11 match the two buckles 10, and the protective cover 5 can be fixed by the combination of the buckles 10 and the hooks 11, so as to improve the stability of the protective cover 5 when moving, and a positioning mechanism 7 is installed on the protective cover 5;

[0019] The positioning mechanism 7 includes a worm 71, a driving member 72, a worm wheel 73, a rotating disk 74, a guide rod 75, a pull plate 76 and a clamping plate 77. The worm wheel 73 is rotatably mounted in the middle of the top of the protective cover 5. The bottom of the worm wheel 73 is fixedly connected to the top of the rotating disk 74. There are two guide rods 75. The two ends of the two guide rods 75 are respectively fixedly connected to the opposite side surfaces of the top of the protective cover 5. The two ends of the two guide rods 75 pass through the sliding holes on the opposite side surfaces of the upper ends of the two clamping plates 77. The clamping plates 77 are L-shaped. The two clamping plates 77 are connected to the laser radar. The scanner body 1 is matched, and the opposite sides of the lower ends of the two clamping plates 77 are fixedly installed with silicone pads 8. The silicone pads 8 can protect the laser radar scanner body 1, and the protective clamping plates 77 cause damage to the laser radar scanner body 1. The bottoms of the upper ends of the two clamping plates 77 are rotatably connected to the tops of one end of the two pull plates 76 respectively, and the tops of the other ends of the two pull plates 76 are rotatably connected to the edges of the bottom of the turntable 74. The two pull plates 76 are symmetrically arranged, and the two ends of the worm 71 are rotatably connected to the opposite sides of the top of the protective cover 5. The worm 71 is connected, and the worm wheel 73 is meshed with the worm wheel 73. There are two driving members 72. The two driving members 72 are respectively rotatably mounted on the two side surfaces of the upper end of the protective cover 5. The shafts on the end surfaces of the two driving members 72 pass through the through holes on the side surfaces of the protective cover 5 and are fixedly connected to the two ends of the worm 71. The driving member 72 is a hand wheel. The protective cover 5 can be stably mounted on the outside of the laser radar scanner body 1 through the mounting plate 3 and the card slot 6.

[0020] The working principle of the utility model is as follows: when the laser radar scanner body 1 is installed, the mounting 4 can be rotated so that the screw 3 on the top of the tripod 2 is screwed into the screw hole at the bottom of the mounting plate 4. When the scanning point is changed, the protective cover 5 can be covered on the mounting plate 4 so that the two ends of the mounting plate 4 enter the card slot 6 at the bottom of the protective cover 5, and are connected with the hook 11 on the mounting plate 4 through the buckles 10 on both sides. The driving member 72 is twisted to make the driving member 72 drive the worm 71 to rotate, so that the worm 71 drives the worm wheel 73 to rotate, so that the worm wheel 73 drives the turntable 74 to rotate, so that the turntable 74 drives one end of the pull plate 76 to rotate toward the middle, so that the other end of the pull plate 76 The two ends simultaneously pull the two clamps 77 to move, so that the two clamps 77 move toward the middle along the direction of the guide rod 75 at the same time, so that the two clamps 77 cooperate to clamp the laser radar scanner body 1 in place. Since the worm 71 and the worm wheel 73 are one-way transmission, they have good self-locking properties, which can keep the clamps 77 stably positioned. At this time, the tripod 2 can be picked up and moved to change the scanning point. During the movement, the positioning of the clamps 77 can prevent the laser radar scanner body 1 from rotating, which can effectively avoid damage to the rotating device on the laser radar scanner 1, and the protective cover 5 will protect the laser scanner body 1 to prevent it from bumping.
