Technical Field

[0001] The present application relates to the technical field of surveying and mapping supports, and in particular to a surveying and mapping support for use on slopes. Background Art

[0002] At present, surveying and mapping tools for flat land environments are already very mature. However, in sloped environments, the problems of poor stability and low measurement accuracy of traditional surveying and mapping instruments due to the inclination of the ground are becoming increasingly prominent.

[0003] In order to overcome the impact of the slope environment on the surveying and mapping support, the existing solutions mainly include: first, increasing the number of support legs to improve stability through more contact points, but this increases the inconvenience of carrying; second, adopting an adjustable toe design so that each foot can adjust the height independently to better fit the uneven surface. However, this design usually requires manual adjustment, which is time-consuming and may still be unstable in extreme cases; third, using a hydraulic system to automatically adjust the length of the legs. Although this improves the degree of automation and scope of application, its high cost limits its widespread application. Utility Model Content

The disassembly mechanism is arranged at the bottom of the support rod 101, and the disassembly mechanism is arranged to facilitate the later disassembly, replacement or maintenance, thereby improving the convenience and flexibility during use;

[0032] Among them, the adjustment mechanism includes a sliding rod 3 slidably installed in the support rod 101, a rack plate 9 fixedly installed on the top of the sliding rod 3, and a gear 10 meshing with the rack plate 9 is rotatably installed on the inner wall of one side of the support rod 101, a connecting column 11 fixedly installed at one end of the gear 10, a first bevel gear 12 fixedly installed at one end of the connecting column 11, and a second bevel gear 13 meshing with the first bevel gear 12 is provided in the support rod 101, a synchronization rod 14 fixedly installed on the second bevel gear 13, a third bevel gear 15 fixedly installed at one end of the top of the synchronization rod 14, and a fourth bevel gear 16 meshing with the third bevel gear 15 is provided in the support rod 101, a fixing column 17 fixedly installed at one end of the fourth bevel gear 16, and a knob 18 fixedly installed at one end of the fixing column 17;

[0033] Among them, the adjusting mechanism also includes an elongated slot 8 opened on one side of the support rod 101 and used for auxiliary installation of the adjusting mechanism. By setting the elongated slot 8, it can play a role of auxiliary installation, thereby avoiding the phenomenon of motion interference. The shell 2 is fixedly installed on one side of the support rod 101, and the side of the shell 2 close to the elongated slot 8 is open. One end of the fixed column 17 passes through one side of the shell 2 and is rotatably installed inside. A support plate 20 is fixedly installed on the inner wall of one side of the shell 2. By setting the support plate 20, it can play a role of auxiliary installation. The support column 19 is rotatably installed on the top of the support plate 20, and the support column 19 is fixedly connected to the second bevel gear 13.

A positioning plate 21 is provided through the outer wall of the bottom of the sliding rod 3, and the same socket 22 is provided on one side of the positioning plate 21 and the sliding rod 3, a positioning column 23 slidably installed in the socket 22, two threads 24 are provided on the outer surfaces of both sides of the positioning column 23, and two nuts 25 screwed on the two threads 24.

[0036] During use, the damper 4 and the damping spring 5 are provided to buffer the unloading force, thereby improving the service life of the self-locking moving wheel 7; by rotating the two nuts 25 and turning the two nuts 25 down, the positioning column 23 can also be removed at this time, thereby releasing the positioning installation of the damper 4 and the self-locking moving wheel 7, thereby facilitating the later disassembly, replacement or maintenance thereof, thereby improving the convenience and flexibility during use.

[0037] The innovative self-locking universal wheels and rack-and-pinion adjustment mechanism enable rapid deployment and height adjustment functions, which not only greatly improves the stability and adaptability of the surveying and mapping bracket 1 in complex terrain, but also makes it easy and quick to operate, making it suitable for long-term outdoor use.

[0038] In addition, it is recommended to use a combination of lightweight and efficient materials, such as carbon fiber and high-performance alloys, to reduce the overall weight while ensuring sufficient mechanical strength.

[0039] The implementation principle of this application is as follows: when the user places the surveying and mapping bracket 1 on a slope, first unlock the self-locking moving wheel 7, push the bracket 1 to the designated location and then lock it again to prevent displacement. Then, according to the actual terrain conditions, turn the knob 18. The rotation of the knob 18 will drive the fixed column 17 and the fourth bevel gear 16 to rotate. The rotation of the fourth bevel gear 16 will drive the third bevel gear 15 and the synchronization rod 14 to rotate. The rotation of the synchronization rod 14 will drive the second bevel gear 13 to rotate. The rotation of the second bevel gear 13 will drive the first bevel gear 12 and the connecting column 11 to rotate. When the tripod is in an ideal balance state, the entire support 1 is in a three-dimensional stable structure and can remain level no matter how the ground is tilted. This greatly improves the stability and reliability of the surveying and mapping support 1 in a slope environment, reduces measurement errors caused by terrain, and greatly shortens the setup time and improves work efficiency through a simple and easy operation process and a quick adjustment mechanism.
