Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, and particularly relates to a portable three-dimensional laser point cloud scanning device. Background Art

[0002] 3D laser point cloud scanning is a method of obtaining the surface geometry and structure of real-world objects using laser ranging technology. It calculates the distance of each point on the object's surface by sending a laser beam and measuring its return time, thereby creating a point cloud data set containing a large number of point coordinates. Objects are usually scanned using a laser scanner body, which consists of a laser transmitter, a receiver, and a control system. It emits a laser beam and records the time and intensity information of the laser beam's return.

[0003] However, in the prior art, when carrying the laser scanner body, it is usually necessary to disassemble the bracket and the scanner and put them into a protective box for carrying. When processing multiple scanning locations in adjacent positions, the scanning equipment needs to be constantly disassembled and stored. The operation process is very cumbersome and not convenient to carry. In order to solve the above problems, we propose a portable three-dimensional laser point cloud scanning device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-5 The utility model is a portable three-dimensional laser point cloud scanning device, comprising a protection box 1, a movable plate 101 is arranged on the top of the protection box 1, and a laser scanner body 102 is fixedly connected to the top of the movable plate 101; and

[0030] Support assembly 2, support assembly 2 is arranged inside protection box 1, support assembly 2 comprises guide rail plate 201, guide rail plate 201 is fixed inside protection box 1, tooth plate 202 is arranged at the bottom of movable plate 101, and limiting groove 203 is arranged on one side of guide rail plate 201; and

[0031] The limit assembly 3 is arranged inside the movable plate 101, and the limit assembly 3 includes a transmission rod 301, the transmission rod 301 is movably connected to the inside of the movable plate 101, a gear 302 is fixedly connected to the surface of the transmission rod 301, a pull ring 303 is fixedly connected to the top of the transmission rod 301, a rotating plate 304 is fixedly connected to the front side of the transmission rod 301, and a limit bolt 305 is penetrated through the front side of the rotating plate 304.

[0032] Specifically, the size of the movable plate 101 is smaller than the size of the top opening of the protective box 1, which can ensure that the movable plate 101 can be completely moved into the protective box 1. The guide plate 201 is divided into two groups and is evenly fixed inside the protective box 1. At the same time, it can also support the up and down movement of the movable plate 101, thereby improving the stability of the laser scanner body 102 during movement. The limiting groove 203 is opened on one side of the guide plate 201 and is divided into 16 groups, which are evenly arranged up and down on one side of the guide plate 201. The internal diameter of the limiting groove 203 is larger than the diameter of the tooth plate 202, which can ensure the normal insertion of the tooth plate 202. Specific embodiment 2

[0034] See also Figure 1-5 On the basis of the specific embodiment 1, the rear side of the limiting bolt 305 is threadedly connected to the movable plate 101, the surface of the guide plate 201 is slidably connected to the inner wall of the movable plate 101, the bottom of the gear 302 is meshed with the tooth plate 202, the surface of the transmission rod 301 is movably connected to the inner wall of the movable plate 101 through a bearing, the surface of the tooth plate 202 is slidably connected to the support block 4, and the top of the support block 4 is fixedly connected to the movable plate 101.

[0035] Specifically, the rotating plate 304 is fixedly connected to the transmission rod 301, and can rotate along with the pull ring 303 when it rotates around the transmission rod 301. At the same time, when the pull ring 303 rotates to a horizontal state, the limiting bolt 305 can be inserted into the rotating plate 304 and threadedly fixed to the movable plate 101 to limit the position of the pull ring 303 and play a locking role. The support block 4 is divided into two groups and is slidably connected to the surface of the tooth plate 202. When the tooth plate 202 is inserted into the limiting groove 203, the top movable plate 101 can be supported. Specific embodiment three

[0037] See also Figure 1-5 On the basis of the first and second specific embodiments, a handle 5 is fixedly connected to the top of the guide plate 201, a moving wheel 6 is fixedly connected to the bottom of the protection box 1, a cover plate 7 is movably connected to the top of the protection box 1 through a hinge, a slot is provided on one side of the cover plate 7, a screw rod 8 is fixedly connected to the front and rear sides of the protection box 1, and an anti-slip threaded column 9 is threadedly connected to the surface of the screw rod 8.

[0038] Specifically, the moving wheels 6 are divided into four groups and are evenly fixed at the four corners of the bottom of the protection box 1. They can support the protection box 1 while being easy to move. The surface of the handle 5 is provided with anti-slip grooves, which can be convenient for the staff to hold. After the laser scanner body 102 is stored in the protection box 1, the protection box 1 can be pulled and carried by pulling the handle 5 and cooperating with the moving wheels 6, thereby improving the convenience during use. The cover plate 7 can block and seal the top of the protection box 1. The anti-slip threaded column 9 can be manually rotated after the protection box 1 is moved to the specified position. Through the reverse thread set on the surface of the screw 8, the anti-slip threaded column 9 is rotated downward and moved downward to contact the ground, thereby increasing the stability during support.

[0039] The working principle of the utility model is as follows: the staff manually rotates and removes the limit bolt 305, and then rotates the pull ring 303 90 degrees counterclockwise with the transmission rod 301 as the axis. When the transmission rod 301 rotates, it drives the gear 302 to rotate. The gear 302 drives the tooth plate 202 to disengage from the limit groove 203, canceling the supporting effect on the movable plate 101. Then, the movable plate 101 can be moved up and down to adjust the use height of the laser scanner body 102 to meet the needs of photographing and scanning objects at different heights. After moving to the specified use height, the pull ring 303 can be rotated 90 degrees clockwise again, and the pull ring 303 is fitted with the movable plate 101. When the pull ring 303 rotates, it drives the tooth plate 202 to be inserted into the limit groove 203 again to fix the use height. At the same time, when it is necessary to transfer the use position of the laser scanner body 102, the movable plate 101 can also be continued to move downward, and the laser scanner body 102 can be moved into the protective box 1, which plays a role of quick storage and is convenient to carry.
