Description

Technical Field

[0001] This application relates to the field of surveying equipment technology, specifically laser point cloud surveying equipment. Background Technology

[0002] Laser point cloud mapping technology, also known as laser point cloud imaging technology, is essentially a form of point cloud technology. Point cloud technology refers to a technology that uses a massive set of points to represent the coordinates and distribution of objects in space. By drawing a large number of points in the air and using these points to form a data set, a three-dimensional model is built to represent the surface characteristics of space. This technology is often used in geological exploration, 3D imaging, and the inspection of large components. Laser point cloud mapping equipment can perform indoor on-site measurement operations as well as exterior facade mapping.

[0003] However, during use, because the 3D laser scanner is supported by a tripod, when the scanner's position needs to be adjusted, the tripod needs to be moved by personnel, which makes the operation process extremely cumbersome. At the same time, it also leads to a decrease in the accuracy of the center adjustment position. When the accuracy of the center adjustment position decreases, blind spots are likely to be generated and the detection effect will be reduced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a laser point cloud mapping device, which has the advantages of enabling the scanner to move horizontally and vertically, increasing the accuracy of the scanner's center position, reducing the generation of scanning blind spots during scanner operation, and increasing the accuracy of scanner detection. It solves the problem that existing technologies require moving a tripod support frame when adjusting the scanner position, which is cumbersome and easily leads to a decrease in the accuracy of the center adjustment position. When the accuracy of the center position adjustment decreases, blind spots are easily generated and the detection effect is reduced.

[0005] To achieve the above objectives, this application provides the following technical solution: a laser point cloud mapping device, including a mounting frame and a scanner body. A mounting base is provided below the scanner body. The inner wall of the mounting base is slidably connected with guide rods arranged at equal intervals. The inner wall of the mounting frame is provided with sliding grooves arranged at equal intervals. A sliding block is slidably connected to the inner wall of each sliding groove. The end of each guide rod is fixedly connected to the side of the corresponding sliding block that is close to it. A threaded rod one is rotatably connected to the inner wall of the mounting frame. A threaded rod two is rotatably connected to the inner wall of the mounting frame. The outer surfaces of both threaded rod one and threaded rod two are threadedly connected to the inner walls of the corresponding sliding blocks. Equally spaced support feet are fixedly connected to the bottom surface of the mounting frame.

[0006] To achieve multi-directional adjustment of the scanner, enabling horizontal and vertical movement, increasing the accuracy of the scanner's center position, reducing blind spots during operation, and improving detection accuracy, a sliding groove is created on the inner wall of the mounting bracket. Sliding blocks are installed on the inner wall of this groove, forming a sliding connection. The scanner body is connected to the mounting base below via a mounting assembly. When the mounting base moves, the scanner body moves accordingly. Rotating threaded rods one and two allows the corresponding sliding blocks to move, which in turn moves the corresponding guide rods, which in turn move the mounting base. This allows the scanner body to move horizontally and vertically, increasing the accuracy of the scanner's center position, reducing blind spots, and improving detection accuracy.

[0007] Furthermore, a fixing cylinder is fixedly connected to the upper surface of the mounting base, a locking bolt is threadedly connected to the inner wall of the fixing cylinder, and a sliding rod is slidably connected to the inner wall of the fixing cylinder.

[0008] The above solution involves installing the fixed cylinder on the upper surface of the mounting base as a fixed connection, installing the fixed cylinder, installing the locking bolt on the inner wall of the fixed cylinder, and installing the sliding rod on the inner wall of the fixed cylinder as a sliding connection. By sliding the sliding rod up and down and then rotating the locking bolt, the sliding rod can be locked, thereby facilitating the adjustment of the height of the scanner body.

[0009] Furthermore, a fixed plate is fixedly connected to the top of the slide rod, and reinforcing rods arranged at equal intervals are fixedly connected to the bottom surface of the fixed plate.

[0010] The above method involves installing a fixed plate at the top of a sliding rod for a fixed connection. The fixed plate can be raised and lowered by the sliding rod, and a reinforcing rod is installed on the bottom of the fixed plate to achieve the installation of the reinforcing rod.

[0011] Furthermore, a limiting member is slidably connected to the outer surface of the fixed cylinder, and the bottom end of each reinforcing rod is fixedly connected to the outer surface of the limiting member.

[0012] The above solution involves setting a limiting component on the surface of the fixed cylinder and connecting the limiting component to the fixed cylinder in a sliding connection. The bottom end of the reinforcing rod is connected to the limiting component. The connection between the reinforcing rod and the limiting component improves the stability of the fixed plate during lifting and lowering.

[0013] Furthermore, a limiting shell is fixedly connected to the upper surface of the fixed disk, and a motor is fixedly installed on the upper surface of the fixed disk.

[0014] The above method involves installing the limiting shell on the upper surface of the fixed plate, and similarly installing the motor on the upper surface of the fixed plate, thereby achieving support and installation for both the limiting shell and the motor.

[0015] Furthermore, the output shaft of the motor is fixedly connected to a gear, and the output shaft of the motor is rotatably connected to the inner wall of the limiting shell.

[0016] The above scheme involves installing a gear on the output shaft of a motor, fixing the gear to the output shaft, and using the motor to make the gear rotate. The output shaft of the motor is rotatably connected to the inner wall of the limiting shell, thereby limiting the motor output shaft.

[0017] Furthermore, the inner wall of the limiting shell is rotatably connected to a mounting rod, and the top end of the mounting rod is fixedly connected to the bottom surface of the scanner body.

[0018] The above solution involves installing the mounting rod on the inner wall of the limiting shell and setting it as a rotatable connection. The limiting shell limits the mounting rod, and the scanner body is connected to the top of the mounting rod. The scanner body can rotate by rotating the mounting rod and the limiting shell.

[0019] Furthermore, a toothed ring is fixedly connected to the outer surface of the mounting rod, and the outer surface of the toothed ring meshes with the outer surface of the gear.

[0020] The above solution involves installing a gear ring on the surface of the mounting rod, connecting the gear ring to a gear, and using a motor to drive the gear to rotate, causing the gear to mesh with the gear ring. This allows the mounting rod to rotate the scanner body, making the plane angle of the scanner body adjustable and increasing the scanning range of the scanner body. The scanning orientation of the scanner body can be adjusted without rotating the bracket.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This laser point cloud mapping equipment, through the setting of components such as sliding blocks, threaded rod one, threaded rod two, and guide rods, has sliding grooves opened in the inner wall of the mounting frame. The sliding blocks are connected to the sliding grooves. By rotating threaded rod one or threaded rod two, the corresponding sliding block drives the guide rod to move, thereby allowing the mounting base to move in the center of the mounting frame. Through the connection between the mounting base and support components and the scanner body, the scanner can move in both horizontal and vertical directions, increasing the accuracy of the scanner's center position, reducing the generation of scanning blind spots during scanner operation, and increasing the accuracy of scanner detection. The sliding rod can be raised and lowered through the fixed cylinder, and locked by the locking bolt, which facilitates the adjustment of the height of the scanner body. The motor drives the gear to rotate, and through the connection between the gear and the gear ring, the mounting rod and the scanner body can rotate. The scanning orientation of the scanner body can be adjusted without rotating the bracket, making operation convenient. Attached Figure Description

The locking bolt 11 is installed on the inner wall of the fixing cylinder 9, and the sliding rod 10 is installed on the inner wall of the fixing cylinder 9 to form a sliding connection. By sliding the sliding rod 10 up and down and then rotating the locking bolt 11, the sliding rod 10 can be locked, thereby facilitating the adjustment of the height of the scanner body 20.

[0033] Please see Figure 1 , Figure 2 and Figure 4 A fixed plate 12 is fixedly connected to the top of the slide rod 10, and reinforcing rods 14 arranged at equal intervals are fixedly connected to the bottom surface of the fixed plate 12. The fixed plate 12 is installed on the top of the slide rod 10 and is set as a fixed connection. The fixed plate 12 can be raised and lowered by the lifting and lowering of the slide rod 10. The reinforcing rods 14 are installed on the bottom surface of the fixed plate 12 to realize the installation of the reinforcing rods 14.

[0034] Please see Figure 1 , Figure 2 and Figure 4 The outer surface of the fixed cylinder 9 is slidably connected to the limiting member 13. The bottom end of each reinforcing rod 14 is fixedly connected to the outer surface of the limiting member 13. The limiting member 13 is set on the surface of the fixed cylinder 9 and connected to the fixed cylinder 9 in a sliding connection. The bottom end of the reinforcing rod 14 is connected to the limiting member 13. The connection between the reinforcing rod 14 and the limiting member 13 can improve the stability of the fixed plate 12 when it is raised and lowered.

[0035] Please see Figure 4 and Figure 5 A limiting shell 15 is fixedly connected to the upper surface of the fixed plate 12, and a motor 16 is fixedly installed on the upper surface of the fixed plate 12. The limiting shell 15 is installed on the upper surface of the fixed plate 12, and the motor 16 is also installed on the upper surface of the fixed plate 12, so as to support and install the limiting shell 15 and the motor 16.

[0036] Please see Figure 5 The output shaft of motor 16 is fixedly connected to gear 17. The output shaft of motor 16 is rotatably connected to the inner wall of limiting shell 15. Gear 17 is installed on the output shaft of motor 16 and fixed to the output shaft of motor 16. Motor 16 enables gear 17 to rotate.

[0037] Please see Figure 5An installation rod 18 is rotatably connected to the inner wall of the limiting shell 15. The top end of the installation rod 18 is fixedly connected to the bottom surface of the scanner body 20. The installation rod 18 is installed on the inner wall of the limiting shell 15 and is configured as a rotatable connection. The limiting shell 15 limits the installation rod 18 and connects the scanner body 20 to the top end of the installation rod 18. The scanner body 20 can rotate by rotating the installation rod 18 and the limiting shell 15.

[0038] Please see Figure 5 A toothed ring 19 is fixedly connected to the outer surface of the mounting rod 18. The outer surface of the toothed ring 19 meshes with the outer surface of the gear 17. The toothed ring 19 is installed on the surface of the mounting rod 18 and connected to the gear 17. The motor 16 drives the gear 17 to rotate, so that the gear 17 meshes with the toothed ring 19. This allows the mounting rod 18 to drive the scanner body 20 to rotate, thereby making the plane angle of the scanner body 20 adjustable, increasing the scanning range of the scanner body 20, and allowing the scanning orientation of the scanner body 20 to be adjusted without rotating the bracket.

[0039] The laser point cloud mapping device in this embodiment uses components such as a sliding block 4, a threaded rod 5, a threaded rod 6, and a guide rod 7. A sliding groove 3 is formed on the inner wall of the mounting frame 1. The sliding block 4 is connected to the sliding groove 3. By rotating the threaded rod 5 or the threaded rod 6, the corresponding sliding block 4 drives the guide rod 7 to move, thereby allowing the mounting base 2 to move in the middle of the mounting frame 1. The connection between the mounting base 2 and the support assembly and the scanner body 20 allows the scanner to move in both horizontal and vertical directions, increasing the accuracy of the scanner's center position, reducing the generation of scanning blind spots during scanner operation, and increasing the accuracy of scanner detection. The fixed cylinder 9 allows the sliding rod 10 to rise and fall, and the locking bolt 11 locks the sliding rod 10, making it easy to adjust the height of the scanner body 20. The motor 16 drives the gear 17 to rotate, and the connection between the gear 17 and the gear ring 19 allows the mounting rod 18 and the scanner body 20 to rotate. The scanning position of the scanner body 20 can be adjusted without rotating the bracket, making operation convenient.

[0040] It should be noted that the motor 16 is a servo motor, which can realize the forward and reverse rotation of the gear 17. When the slide bar 10 is raised or lowered to a certain height, the locking bolt 11 is rotated so that the end of the locking bolt 11 can press the slide bar 10 tightly, thereby locking the slide bar 10 and preventing the slide bar 10 from moving.

[0041] The working principle of the above embodiments is as follows:

[0042] When using the device, first, place the device in the desired position using the mounting bracket 1 and the support leg 8. Then, move the slide bar 10 to raise and lower the scanner body 20. After raising and lowering to the specified height, turn the locking bolt 11 to lock the slide bar 10, thus adjusting the height of the scanner body 20. When adjusting the orientation of the scanner body 20, turn the threaded rod 5 or the threaded rod 6 to move the corresponding sliding block 4, which in turn moves the guide rod 7, allowing the mounting base 2 to move in the middle of the mounting bracket 1. Through the connection between the mounting base 2, the upper slide bar 10, the fixed plate 12, and other components with the scanner body 20, the scanner can move in both horizontal and vertical directions. Compared to the prior art where the operator carries the entire triangular support frame and scanner, this increases the accuracy of the scanner's center position, reduces the generation of scanning blind spots during scanner operation, and increases the accuracy of scanner detection. The motor 16 drives the gear 17 to rotate, and through the connection between the gear 17 and the gear ring 19, the mounting rod 18 and the scanner body 20 rotate. The scanning orientation of the scanner body 20 can be adjusted without rotating the support, making the operation of the scanner body 20 more convenient.
