[0002] With the advancement of technology, 3D laser scanners have been widely used in surveying and mapping work. 3D laser scanners have broken through the traditional single-point measurement mode and can quickly obtain high-precision massive point cloud data. The principle is to use laser detection technology to obtain the distance from the measured target to the scanning center, and the encoder is controlled by a precision clock to synchronously measure the horizontal scanning angle observation value and the vertical scanning angle observation value of each laser pulse. The spatial 3D coordinates of the measured point can be calculated from the spatial 3D geometric relationship through a line element and two angle elements. In surveying and mapping work, a 3D laser scanner is needed to obtain the high-precision 3D coordinates of the measured object.

[0027] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] When a terrestrial three-dimensional laser scanner is working, the scanner body is generally installed on the top of a tripod, and the laser scanner body is supported by the tripod to ensure that the laser scanner can work normally. The existing laser scanner body is generally connected between the three-dimensional laser scanner and the tripod by multiple bolts.

[0030] In the related art, the 3D laser scanner does not have a good and convenient installation and disassembly function. It is necessary to tighten multiple bolts to achieve the installation and disassembly of the 3D laser scanner. During use, it brings inconvenience to the installation and disassembly operations of the workers, making the 3D laser scanner less convenient to use.

[0031] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a three-dimensional laser scanner fascia gun. When the three-dimensional laser scanner body 13 needs to be disassembled, it is only necessary to pull the protective shell 24. The protective shell 24 drives the fixing rod 22 to slide inside the slide groove 21 and release the fixation of the three-dimensional laser scanner body 13 to achieve the disassembly of the three-dimensional laser scanner body 13, thereby achieving the effect of convenient installation and disassembly, providing convenience for the staff in installation and disassembly operations, and thus achieving the effect of improving the convenience of using the three-dimensional laser scanner.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1 - Figure 4 The embodiment of the present application provides a three-dimensional laser scanner, including a main body component 1, the main body component 1 includes a tripod 11 with a connecting plate 12 on the top, a three-dimensional laser scanner body 13 is arranged on the connecting plate 12, and a mounting component 2 is arranged on the connecting plate 12, the mounting component 2 includes a slide groove 21 opened on the connecting plate 12, a fixing rod 22 slidably connected to the connecting plate 12, a fixing groove 23 opened on the three-dimensional laser scanner body 13, and the fixing rod 22 is embedded in the fixing groove 23, a protective shell 24 is fixedly connected to the outside of the fixing rod 22 and slidably connected to the connecting plate 12, a spring 25 is sleeved on the outside of the fixing rod 22, and the two ends are respectively fixedly connected to the connecting plate 12 and the protective shell 24, and the mounting component 2 is provided with two groups, and is symmetrically arranged.

[0034] When in use, in surveying and mapping work, it is necessary to obtain high-precision three-dimensional coordinates of the measured object through the three-dimensional laser scanner body 13. First, the three-dimensional laser scanner body 13 is installed on the top of the tripod 11 through the connecting plate 12, and the three-dimensional laser scanner body 13 is supported by the tripod 11. The telescopic two-section tripod 11 is preferably used, which has been fully disclosed and will not be described in detail here. During the installation operation, a groove body is opened on the connecting plate 12, and two protective shells 24 are fitted with the groove body. The two protective shells 24 are pulled to both sides by manpower so that the two protective shells 24 slide in the opposite direction inside the groove body under the limit of the connecting plate 12, and then the two fixed rods 22 fixedly connected to the two protective shells 24 slide inside the two slide grooves 21, so that the two springs 25 fixedly connected to the two protective shells 24 obtain compression space under the support of the connecting plate 12, so that the two The protective shell 24 and the two fixing rods 22 are far away from each other. At this time, the bottom of the three-dimensional laser scanner body 13 is embedded in the placement groove provided on the connecting plate 12. When the three-dimensional laser scanner body 13 is completely embedded in the interior of the connecting plate 12, the manpower is released so that the two springs 25 drive the two protective shells 24 and the two fixing rods 22 to reset through their own elastic force. A groove body in which the fixing rods 22 can slide is provided on the connecting plate 12. The fixing rods 22 slide into the fixing grooves 23 through the groove body, so that the two fixing rods 22 are embedded in the interior of the two fixing grooves 23 to fix the three-dimensional laser scanner body 13. When the two fixing rods 22 slide out of the interior of the two fixing grooves 23, the three-dimensional laser scanner body 13 can be removed from the connecting plate 12, thereby achieving the effect of convenient installation and disassembly, providing convenience for the installation and disassembly operations of the staff, and thus achieving the effect of improving the convenience of using the three-dimensional laser scanner.

[0035] Specifically, the connecting plate 12 is hollowed out, and the three-dimensional laser scanner body 13 is located in the middle of the connecting plate 12 and is partially embedded in the connecting plate 12 .

[0036] In some embodiments, the installation assembly 2 further includes a limit block 26 fixedly connected to the fixing rod 22 and slidably connected to the sliding groove 21 .

[0037] Specifically, the diameter of the limiting block 26 is larger than the diameter of the fixing rod 22 and fits with the inner wall of the slide groove 21 to prevent the fixing rod 22 from sliding out of the slide groove 21 when sliding inside the slide groove 21, thereby improving the sliding stability.

[0038] In some embodiments, a protective component 3 is provided on the protective shell 24, and the protective component 3 includes a support rod 31 fixedly connected to the protective shell 24, a protective plate 32 slidably connected to the outside of the support rod 31, and a spring 33 is sleeved on the outside of the support rod 31, and both ends are fixedly connected to the protective shell 24 and the support rod 31.

[0039] When in use, falling objects generate impact force on the protective plate 32, causing the protective plate 32 to slide on the outer wall of the support rod 31, and then the spring 2 33 fixedly connected to the protective plate 32 generates elastic support under the support of the protective shell 24, so that the spring 2 33 buffers the impact force generated by the falling objects, thereby achieving a buffering effect, preventing the falling objects from colliding with the three-dimensional laser scanner body 13 and causing damage, thereby achieving the effect of improving the protectiveness of the three-dimensional laser scanner.

[0040] Specifically, the tops of the two protective shells 24 are both provided with protection components 3 , and are symmetrically arranged with the contact surface of the two protective shells 24 as the center.

[0041] In some embodiments, the installation assembly 2 also includes a handle 27 fixedly connected to the protective shell 24. During installation and disassembly operations, the two protective shells 24 can be driven to slide on the connecting plate 12 by pulling the two handles 27 to both sides, thereby further improving the convenience of use.

[0042] In some embodiments, the tripod 11 is connected to the connecting plate 12 by bolts. Two bolts are located in the middle of the connecting plate 12 and are threadedly connected to the inside of the tripod 11 and the inside of the connecting plate 12, which makes it convenient for staff to perform maintenance and replacement operations on the tripod 11 and improves the use effect.

[0043] In some embodiments, the support rod 31 and the spring 2 33 are a group, and two groups are arranged on each protective plate 32. The two support rods 31 can be used to limit the protective plate 32 to prevent the protective plate 32 from rotating, and the two springs 2 33 improve the buffering effect.

[0044] In some embodiments, the protective plate 32 is provided with an arc-shaped surface, and the top of the protective plate 32 is arc-shaped, so that falling objects can fall directly from the protective plate 32, further improving the use effect.
