DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] Combination Figures 1 to 5The scanning device shown is suitable for collecting station geographic space data, including a support base 1 that bears the load and supports the entire device, a cylindrical shell 3 is fixed on the support base 1, a movable first mobile frame 4 is installed in the shell 3, and the movement direction of the first mobile frame 4 is perpendicular to the horizontal plane, so that the scanning device can be moved and scanned at different heights; a rotatable round table 8 is arranged on the side of the first mobile frame 4 away from the support base 1, so that the device can be rotated on the horizontal plane, thereby expanding the scanning range and flexibility; a movable second mobile frame 15 is installed on the round table 8, and a laser scanner 16 is installed on the top of the second mobile frame 15, and the laser scanner 16 is used to scan the three-dimensional data of the station geographic space. Among them, the second mobile frame 15 can be pivoted relative to the round table 8, and can also move along its own central axis direction. This design enables the laser scanner 16 to accurately scan at different angles and positions to obtain the three-dimensional data of the station geographic space.

[0030] In some feasible embodiments of the present application, a driving wheel 2 is connected to the bottom of the support base 1 to provide additional driving force and motion support for the entire device.

[0031] Based on the above device structure, it can be understood that, compared with the traditional scanner bracket, the structural design of the first mobile frame 4, the round table 8 and the second mobile frame 15 makes the scanning device highly flexible, not only can it move in the vertical direction, but also can rotate and adjust the angle in the horizontal plane to adapt to different collection needs and scenes. The pivoting movement of the second mobile frame 15 and the movement along the central axis direction can realize multi-angle scanning, so that the device can obtain data from different directions and angles, providing more comprehensive information for geographic information and spatial analysis.

[0032] Regarding the structures of the first mobile frame 4, the round table 8 and the second mobile frame 15, more specifically, in some feasible embodiments of the present application, as Figure 1 and Figure 2 As shown, a screw rod 5 and a round rod 6 perpendicular to the horizontal plane are fixedly installed on the support seat 1 inside the shell 3, and the screw rod 5 is rotatably connected to the support seat 1. The first movable frame 4 passes through the screw rod 5 and the round rod 6, is threadedly connected to the screw rod 5, and is slidably connected to the round rod 6. By rotating the screw rod 5 and the number of turns of the screw rod 5, the first movable frame 4 can be accurately moved and positioned along the vertical direction.

[0033] refer to Figure 3 , Figure 3 This is a schematic diagram of a structure for driving a truncated table 8 to rotate in a scanning device provided in an embodiment of the present application. A first fixed frame 7 is provided on the first movable frame 4 for supporting and connecting the truncated table 8. The truncated table 8 is rotatably connected to the first fixed frame 7, wherein:

[0034] A first bevel gear 9 is fixed to one side of the truncated table 8 close to the first fixed frame 7, and the center axis of the first bevel gear 9 is parallel to the center axis of the truncated table 8, preferably the center axis of the first bevel gear 9 coincides with the center axis of the truncated table 8, thereby ensuring the smoothness and stability of the transmission.

[0035] The first fixed frame 7 is internally rotatably connected to the second bevel gear 10, and the central axis of the second bevel gear 10 is perpendicular to the central axis of the first bevel gear 9. The second bevel gear 10 is meshed with the first bevel gear 9, so that power can be transmitted to the first bevel gear 9, thereby driving the round table 8 to rotate. This design ensures the rotation stability and controllability of the round table 8, and provides the scanning device with the function of rotating and adjusting the angle.

[0036] Regarding the pivotal movement of the second mobile frame 15 relative to the round table 8, in some feasible embodiments of the present application, refer to Figure 4 , Figure 4 A schematic diagram of a limit block 13 in a scanning device provided in an embodiment of the present application, which is engaged in a limit groove 14 of a second fixed frame 11, wherein a second fixed frame 11 is fixedly mounted on a round table 8 for supporting and connecting a second movable frame 15, wherein the second movable frame 15 is connected to a mounting frame 12 by sliding, and the mounting frame 12 is pivotally connected to the second fixed frame 11. Wherein:

[0037] The second fixed frame 11 is internally rotatably connected to a limiting block 13 , wherein the axis thereof is perpendicular to the central axis of the truncated table 8 . The limiting block 13 functions to limit the pivoting range of the second movable frame 15 to ensure the accuracy and stability of the movement.

[0038] The mounting frame 12 is provided with a stopper groove 14 adapted to the stopper block 13, and the stopper block 13 can be engaged in the stopper groove 14. This design enables the mounting frame 12 to rotate when the stopper block 13 rotates, and this rotational movement causes the second mobile frame 15 to pivot relative to the round table 8, thereby realizing the overall rotation and angle adjustment of the laser scanner 16 on the second mobile frame 15 in space. The design of the stopper block 13 engaging with the stopper groove 14 can ensure its stability and controllability during the pivoting movement.

[0039] Regarding the second mobile frame 15, in the process of pivoting relative to the round table 8, it moves along its own central axis. Figure 5, a rack 17 is arranged in the mounting frame 12, and the rack 17 is parallel to the central axis of the second mobile frame 15. The function of the rack 17 is to provide guidance and support for movement along the direction of its own central axis. A gear 18 is rotatably connected to the second mobile frame 15, and the rotation plane of the gear 18 is parallel to the central axis of the second mobile frame 15. Such a design enables the gear 18 to mesh with the rack 17 in the mounting frame 12 to achieve movement along the direction of its own central axis. When the gear 18 rotates, its teeth mesh with the rack 17 in the mounting frame 12, which drives the second mobile frame 15 to move along the direction of its own central axis. Through the cooperation of the gear 18 and the rack 17, the second mobile frame 15 can achieve movement along the direction of its own central axis while pivoting.

[0040] On the basis of the above, a slide groove parallel to the central axis of the second mobile frame 15 is provided on the mounting frame 12, and a slider is provided on the second mobile frame 15, and the slider is slidably connected in the slide groove. Combined with the design of the slider and the slide groove, the second mobile frame 15 will move more stably and controllably along its own central axis while pivoting. This structural design provides the scanning device with more dimensional movement options, making the data acquisition process more flexible and efficient.

[0041] According to the scanning device provided in the above embodiment of the present application, the present application does not make any additional restrictions on how to drive the rotation of the screw 5, the rotation of the second bevel gear 10, the rotation of the limit block 13 and the rotation of the gear 18, including but not limited to motor drive.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
