Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, and more specifically, to a three-dimensional laser scanning surveying device. Background Technology

[0002] 3D laser scanning technology is the latest technology in the surveying and mapping field, and can be applied to various areas of the industry. It not only comprehensively improves the surveying environment but also enhances work efficiency. Its effective application in building facade surveying has achieved results that traditional techniques could not. When scanning building facades, 3D laser scanning devices need to be fixed in place using a support frame.

[0003] For example, Chinese patent CN216843995U proposes a three-dimensional laser scanning device for surveying residential properties. This device has lifting and circumferential rotation adjustment functions. However, in the implementation process, the bottom of this device is designed as a movable base, which results in the lack of a leveling function and poor adaptability. Furthermore, it does not have a locking function after rotation, which can easily cause the three-dimensional laser scanning surveyor to deflect during use, affecting not only the user's operation but also the accuracy of the survey.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] See attached document Figure 1 As shown, a three-dimensional laser scanning mapping device includes a leveling frame mechanism 1, a height rod mechanism 2, a fixed base 3, a rotating roller 4, a mounting base 5, a locking mechanism 6, and a three-dimensional laser scanning mapping instrument body 7. In this embodiment, the leveling frame mechanism 1 is used to contact the ground and has a leveling function. The leveling frame mechanism 1 is connected to the fixed base 3 through the height rod mechanism 2, so that the position of the three-dimensional laser scanning mapping instrument body 7 can be adjusted along the height direction. The top of the fixed base 3 is rotatably connected to the mounting base 5 through the rotating roller 4, so that the position of the three-dimensional laser scanning mapping instrument body 7 can be adjusted along the circumferential direction. The locking mechanism 6 provided on the fixed base 3 fixes the position of the rotating mounting base 5. The three-dimensional laser scanning mapping instrument body 7 is provided on the mounting base 5.

[0025] In this embodiment, the device not only meets the functions of height adjustment and circumferential rotation adjustment, but also has a leveling function and a locking function after the three-dimensional laser scanning mapping instrument body 7 rotates.

[0026] Specifically, regarding the structure of the leveling frame mechanism 1 in the above embodiments:

[0027] See attached document Figure 1As shown, the leveling frame mechanism 1 includes a base 11, a bubble level 12, an internally threaded tube 13, an externally threaded rod 14, and a grounding seat 15. The bubble level 12 is installed on the side of the base 11, and three internally threaded tubes 13 are arranged around the bottom circumference of the base 11. The three internally threaded tubes 13 are inclined outward to form a stable triangular structure, and each internally threaded tube 13 is connected to the grounding seat 15 through an externally threaded rod 14. During implementation, the operator places the leveling frame mechanism 1 on the ground, observes the state of the bubble level 12 from this position, and then adaptively adjusts the extension length of the corresponding externally threaded rod 14 until the bubble level 12 is in a horizontal state.

[0028] In the above embodiments, specifically regarding the structure of the height lever mechanism 2:

[0029] See attached document Figure 1 As shown, the height rod mechanism 2 includes an outer tube 21, an inner rod 22, and a fixing bolt 23. The outer tube 21 is vertically mounted on the base 11, and the inner cavity of the outer tube 21 has a rectangular structure and is connected to the inner rod 22. The inner rod 22 matches the inner cavity structure of the outer tube 21 and is slidably mounted in the inner cavity of the outer tube 21. The side of the outer tube 21 is threaded with a fixing bolt 23, and the end of the fixing bolt 23 is connected to the inner cavity of the outer tube 21 and abuts against the inner rod 22 to fix the position of the inner rod 22 after the height is adjusted.

[0030] In the above embodiments, specifically regarding the structure of the locking mechanism 6:

[0031] See attached document Figure 3 As shown, the locking mechanism 6 includes a guide rod 61, a top ring 62, a spring 63, and a pressure ring 64. There are two guide rods 61, which are vertically slidably mounted on the fixed base 3. The tops of the two guide rods 61 are connected to the top ring 62. The top ring 62 is sleeved outside the rotating roller 4 and located below the mounting base 5. A spring 63 is provided between the top ring 62 and the fixed base 3 for sleeved outside the guide rods 61. The bottoms of the two guide rods 61 are connected to the pressure ring 64. The pressure ring 64 is located below the fixed base 3 and sleeved outside the inner rod 22. During implementation, the operator pulls the pressure ring 64 downward to move the top ring 62 downward and away from the mounting base 5. At the same time, the spring 63 is compressed. At this time, the position of the three-dimensional laser scanning mapping instrument body 7 can be adjusted in the circumferential direction. After the adjustment is completed, the pressure ring 64 is released, the spring 63 rebounds, and the top ring 62 moves upward to contact the bottom of the mounting base 5 to fix the mounting base 5.

[0032] In addition, considering the contact effect between the top ring 62 and the mounting base 5, the locking mechanism 6 also includes a rubber ring 65, which is disposed on the top of the top ring 62 for contact with the bottom of the mounting base 5, thereby improving the fixing effect on the mounting base 5.

[0033] In the above embodiments, considering the protective effect of the three-dimensional laser scanning mapping instrument body 7 when not in use, therefore, refer to the appendix. Figure 4 As shown, the mounting base 5 is also equipped with a set of protective covers 8, which cover the outside of the three-dimensional laser scanning mapping instrument body 7.

[0034] Regarding the structure of the protective shield 8 in the above scheme:

[0035] See attached document Figure 5 As shown, the protective cover 8 includes a cover body 81 and a magnetic ring 82. In this solution, the mounting base 5 is made of steel, the bottom of the cover body 81 is open, and a magnetic ring 82 for magnetic adsorption with the mounting base 5 is installed on its bottom surface. During implementation, when the 3D laser scanning surveying instrument body 7 needs to be used, the cover body 81 can be removed directly. When the 3D laser scanning surveying instrument body 7 does not need to be used, the cover body 81 can be directly placed over the outside of the 3D laser scanning surveying instrument body 7.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
