[0026] The four corners of the top of the movable plate 9 are bolted with telescopic rods 13 , and the top of the telescopic rods 13 is bolted with a placement plate 14 . The placement plate 14 is supported by the telescopic rods 13 , and the placement plate 14 is connected to the movable plate 9 at the same time.

[0027] The four corners of the top of the movable plate 9 are hinged with folding plates 15, the top of the folding plates 15 are bolted with springs 16, and the other ends of the springs 16 are bolted to the bottom of the placement plate 14, so that the folding plates 15 rotate according to their hinges as the axis, and the bottom springs 16 serve as auxiliary buffer components.

[0028] The upper part of the inner side of the folding plate 15 is hinged with a locking plate 17, so that the locking plate 17 serves as a clamping component to fix the laser radar.

[0029] A surveying laser radar 18 is arranged on the top of the placement plate 14, so that the surveying laser radar 18 serves as the surveying and mapping subject.

[0030] A fixing plate 19 is bolted to both the front and rear sides of the top of the mobile platform 1, and the left side of the fixing plate 19 is rotatably connected to the right side of the screw rod 7 through a bearing. The installation of the fixing plate 19 improves the stability of the screw rod 7 during rotation.

[0031] Push handles 20 are bolted to the front and rear of the left side of the mobile platform 1 , so that the user can use the push handles 20 to drive the mobile platform 1 to move.

[0032] Refer to the instruction manual Figure 1-4Working principle: through the first installation frame 2, the first slider 3, the connecting rod 4, the threaded sleeve 5, the servo motor 6 and other components, during the use of the device, if the surveying and mapping height needs to be adjusted, it is only necessary to control the servo motor 6 to make the servo motor 6 drive the screw rod 7 to rotate. During the rotation of the screw rod 7, the threaded sleeve 5 on its surface will drive the horizontal movement of the threaded sleeve 5. When the threaded sleeve 5 moves, it will synchronously drive the connecting rod 4 and the first slider 3 on both sides thereof to move horizontally inside the first installation frame 2. The second connecting rod 12 is driven to retract inwardly through the first connecting rod 8, thereby pushing the upper moving plate 9 to move vertically, adjusting the surveying and mapping height of the upper moving plate 9 and the laser radar, ensuring that the laser radar has sufficient surveying and mapping range, and improving the working accuracy of the surveying and mapping laser radar 18.

When the mobile platform 1 vibrates during the movement, the spring 16 and the folding plate 15 components can prevent the vibration generated during transportation from damaging the surveying and mapping laser radar 18 above, thereby ensuring the normal progress of subsequent surveying and mapping work.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
