Description

Technical Field

[0001] This utility model belongs to the field of geographic information modeling technology, and in particular relates to a novel automatic leveling and rotating scanning device for GIS geographic information 3D modeling. Background Technology

[0002] A GIS geographic modeling scanner is a device that uses laser ranging technology to acquire three-dimensional coordinate data of an object's surface. It is primarily used to generate high-precision point cloud data and construct three-dimensional models, and is widely applied in urban planning, architectural surveying, and other fields. Currently, when using a scanner, an automatic leveling and rotating scanning device is usually required to assist in its installation and automatic leveling. Existing GIS geographic information 3D modeling automatic leveling and rotating scanning devices include a rotating scanner mechanism and a walking base. The rotating scanner mechanism is mounted on the walking base, which includes a chassis, battery pack, wheels, an X-axis leveling mechanism, an X-axis inclinometer, and a PLC controller. This existing GIS geographic information 3D modeling automatic leveling and rotating scanning device adjusts the angle of the T-shaped support via an electric telescopic rod, thereby adjusting the scanner's tilt angle. However, because the installation positions of the electric telescopic rod, the T-shaped support, and the chassis are fixed, the scanner's tilt angle can only be adjusted in a fixed direction, limiting its adjustment range. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a novel automatic leveling and rotating scanning device for 3D modeling of GIS geographic information, which increases the adjustment range of the scanner's tilt angle and enables more comprehensive adjustment of the scanner's tilt angle.

[0004] This utility model is achieved through the following technical solution: A novel GIS geographic information 3D modeling automatic leveling and rotating scanning device includes a movable base. A rotary motor is fixedly mounted on the upper part of the movable base. An installation plate is fixedly mounted on the upper part of the output shaft of the rotary motor. A rotating rod assembly is mounted on the upper part of the installation plate. An extension rod is mounted on the upper part of the rotating rod assembly. The rotating rod assembly includes an annular electric guide rail and a support rod. A ball joint is fixedly mounted on the lower part of the support rod. The ball joint and the annular electric guide rail are located at the same center. A first mounting frame is fixedly mounted on the upper part of the slider of the annular electric guide rail. An annular guide rail is fixedly mounted on the upper external end of the support rod. A second mounting frame is fixedly mounted on the external end of the slider of the annular guide rail. An electric telescopic rod is mounted between the second mounting frame and the first mounting frame via a pin. An tilt sensor is fixedly mounted on one side of the upper end of the support rod, and fixing bolts are arranged longitudinally on the other side.

[0005] Preferably, the upper part of the extension rod is integrally provided with a mounting base.

[0006] Preferably, a scanner is fixedly mounted on the upper part of the mounting base.

[0007] Preferably, the lower end of the extension rod is inserted into the inside of the support rod and fixed by a fixing bolt.

[0008] Preferably, the annular electric conductive rail and the ball joint are both fixedly installed on the upper part of the mounting plate.

[0009] Preferably, the movable base is equipped with a PLC controller, and the rotary motor, the annular electric guide rail, the electric telescopic rod, and the tilt sensor are all electrically connected to the PLC controller.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the arrangement of the annular electric guide rail, support rod, ball joint, first mounting bracket, annular guide rail, second mounting bracket, electric telescopic rod, tilt sensor, and fixing bolts facilitates more comprehensive adjustment of the angles of the support rod and scanner, resulting in more comprehensive leveling.

[0015] The present invention will now be described in detail with reference to the accompanying drawings. As shown in Figure 1, a novel GIS geographic information 3D modeling automatic leveling and rotating scanning device includes a movable base 1, a rotary motor 11 fixedly mounted on the upper part of the movable base 1, an mounting plate 2 fixedly mounted on the upper part of the output shaft of the rotary motor 11, a rotating rod assembly 6 mounted on the upper part of the mounting plate 2, and an extension rod 3 mounted on the upper part of the rotating rod assembly 6.

[0016] In this embodiment, specifically, the upper part of the extension rod 3 is integrally provided with a mounting base 4.

[0017] In this embodiment, specifically, a scanner 5 is fixedly mounted on the upper part of the mounting base 4.

[0018] In this implementation plan, in conjunction with the appendix Figure 2 As shown, the rotating rod assembly 6 includes an annular electric guide rail 61 and a support rod 62. A ball joint 63 is fixedly installed on the lower part of the support rod 62. The ball joint 63 and the annular electric guide rail 61 are located at the same center. A first mounting bracket 64 is fixedly installed on the upper part of the slider of the annular electric guide rail 61. An annular guide rail 65 is fixedly installed on the outer side of the upper end of the support rod 62. A second mounting bracket 66 is fixedly installed on the outer side of the slider of the annular guide rail 65. An electric telescopic rod 67 is installed between the second mounting bracket 66 and the first mounting bracket 64 via a pin. An inclination sensor 68 is fixedly installed on one side of the upper end of the support rod 62, and fixing bolts 69 are arranged longitudinally on the other side. When the inclination sensor 68 detects a deviation in the inclination angle of the support rod 62, it transmits the data to... The PLC controller drives the first mounting bracket 64 and the electric telescopic rod 67 to move via the annular electric guide rail 61. One end of the output rod of the electric telescopic rod 67 can move along the annular guide rail 65 via the second mounting bracket 66, thereby rotating synchronously with the first mounting bracket 64 to adjust the position of the electric telescopic rod 67. When the output rod of the electric telescopic rod 67 extends or retracts, it can drive the support rod 62 to tilt. The lower end of the support rod 62 rotates relative to the mounting plate 2 via the ball joint 63, thereby adjusting the angle of the support rod 62 to achieve the leveling function. The user can adjust the height of the extension rod 3 by loosening the fixing bolt 69, and then lock the fixing bolt 69 after adjustment to adjust the height of the mounting base 4 and the scanner 5.

[0019] In this embodiment, specifically, the lower end of the extension rod 3 is inserted into the inside of the support rod 62 and fixed by the fixing bolt 69.

[0020] In this embodiment, specifically, the annular electric conductive rail 61 and the ball joint 63 are both fixedly installed on the upper part of the mounting plate 2.

[0021] In this embodiment, specifically, the movable base 1 is equipped with a PLC controller, and the rotary motor 11, the annular electric guide rail 61, the electric telescopic rod 67, and the tilt sensor 68 are all electrically connected to the PLC controller.

[0022] Working principle

[0023] In this invention, the movable base 1 is used to move the scanner 5. When it moves to the scanning position, the rotary motor 11 is used to drive the scanner 5 to rotate, so that the scanner 5 can rotate and scan. The rotating rod assembly 6 is used to level the scanner 5 more comprehensively. The tilt sensor 68 is used to detect the tilt angle of the support rod 62.

[0024] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
