A mobile geographical surveying and mapping device

Abstract

This invention provides a mobile geographic surveying and mapping device, including a surveying and mapping component and a synchronous adjustment mechanism. The surveying and mapping component includes a base, an adjustment seat, a surveying and mapping instrument, and three support frames. The adjustment seat is mounted on top of the base, and the surveying and mapping instrument is mounted on top of the adjustment seat. This invention uses the synchronous adjustment mechanism to synchronously adjust the tilt angle of the support frames, enabling rapid deployment of the support frames. When the surveying and mapping device needs to be moved, a moving traction frame uses a through-slot to drive a connecting rod. The moving connecting rod drives the casters to contact the ground, directly raising the extension mechanism and support frames. This eliminates the need for storage, allowing the surveying and mapping device to be moved, simplifying the operation. Furthermore, a communication mechanism can be used to synchronously control the moving auxiliary mechanism, ensuring the overall stability of the equipment during operation.

[0069] When the present invention is working: the measuring and mapping equipment is placed at the specified position according to actual needs, and then the connecting tube 203 is driven to rotate by rotating the screw ring sleeve 74, and the rotating connecting tube 203 uses the worm shaft 202 to drive the three sector gears 201 to move simultaneously, and the moving sector gears 201 drive the support frame 104 to move, so as to synchronously adjust the inclination angles of the three support frames 104, and at the same time, the moving support frame 104 drives the connecting frame 71 to move, and the moving connecting frame 71 drives the slip ring 72 to slide on the connecting tube 203 to ensure the overall stability of the support frame 104.

[0071] After the base 101 is leveled, the adjustment base 102 and the measuring and mapping instrument 103 are installed between the base 101 and adjusted to complete the assembly operation of the measuring and mapping equipment.

[0072] When the equipment needs to be moved, the communication module 604 receives the command of the control terminal and transmits the command to the control module 602. Then, the control module 602 uses the relay 603 to start the synchronous motor 401 according to the command. The working synchronous motor 401 drives the screw 405 to move. The moving screw 405 drives the traction frame 402 to move by using the thread. The moving traction frame 402 drives one end of the connecting rod 403 to move by using the through groove 404. Then, the moving connecting rod 403 drives the universal wheel 406 to contact the ground. Then, the connecting rod 403 that continues to move drives the universal wheel 406 to lift the cone head 301 and the support frame 104 off the ground as a whole. Then, the universal wheel 406 can be used to push the equipment to move.

[0073] When the equipment is moved, it only needs to drive the screw 405 to rotate in the opposite direction through the synchronous motor 401, and the traction frame 402 moving in the opposite direction can drive the connecting rod 403 and the universal wheel 406 to reset, so that the cone head 301 can contact the ground again, so as to continue the surveying and mapping work.

[0074] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
