Description

Technical Field

[0001] This utility model relates to the field of total station technology, and in particular to a quick positioning bracket for a total station used in engineering surveying. Background Technology

[0002] A total station is a high-tech surveying instrument integrating optics, mechanics, and electronics. It is mainly used for precision engineering surveying or deformation monitoring in large-scale above-ground construction and underground tunnel construction. It integrates the functions of measuring horizontal angles, vertical angles, distances (slope distances, horizontal distances), and elevation differences. Once the instrument is set up, all the measurement work at the station can be completed. It is widely used in the field of engineering surveying. When using a total station, it needs to be positioned and supported by a bracket. Existing total station positioning brackets have certain drawbacks. The brackets are large and heavy, making them inconvenient to carry when conducting field surveys. When the total station is unfolded, it needs to be supported by a support. When the total station needs to be moved, the bracket must be lifted, its position adjusted, and then its position fixed, which is inconvenient. Therefore, we propose a rapid positioning bracket for total stations used in engineering surveying. Utility Model Content

The limiting plate 203 is fixedly installed on the lower surface of the central shaft 202. An adjusting ring 206 is fitted onto the surface of the central shaft 202. A first screw hole 204 is formed on the surface of the adjusting ring 206, and a first bolt 205 is embedded inside the first screw hole 204. The first bolt 205 fixes the adjusting ring 206 to the central shaft 202 through friction. Diagonal rods 201 are movably installed on the lower surface of the adjusting ring 206. There are three sets of diagonal rods 201. Support rod body 3 includes a first rod body 301, a limiting hole 302, a second… The first rod 301 comprises a rod body 303, a spring 304, a fixing plate 305, a through hole 306, and a limiting rod 307. The fixing plate 305 is fixedly mounted on the lower surface of the first rod body 301. A through hole 306 is formed on one side of the fixing plate 305, and a limiting rod 307 is embedded inside the through hole 306. A spring 304 is fitted onto the surface of the limiting rod 307, with one end fixed to one side of the fixing plate 305 and the other end fixed to the surface of the limiting rod 307. A second rod body 303 is embedded on the lower surface of the first rod body 301. Multiple limiting holes 302 are formed on the surface of the second rod body 303, providing limiting... Rod 307 is embedded inside the limiting hole 302; the central shaft 202 is fixedly installed on the lower surface of the fixed platform 1 at the middle position; the first rods 301 are all movably installed on the lower surface of the fixed platform 1 at the edge position; the diagonal rods 201 are respectively movably installed on the surface of the first rods 301 at the lower position; the positioning structure 4 includes a positioning plate 401, a moving wheel 402, a sliding groove 403, a second screw hole 404, a conical block 405, a second bolt 406, a third screw hole 407, and a slider 408. The slider 408 is located inside the sliding groove 403 and will not detach from the sliding groove 403. The lower surface of the positioning plate 401 is fixedly installed with a conical block 405.

In use, the support rod body 3 is unfolded by adjusting the structure 2 and positioned by the positioning structure 4, allowing the total station to be mounted on the fixed platform 1 for measurement. Moving the adjusting ring 206 downwards causes the first rod body 301 to unfold under the action of the inclined rod 201. Tightening the first bolt 205 inside the first screw hole 204 fixes the position of the adjusting ring 206 and the central axis 202, thus fixing the angle of the first rod body 301. Pulling the limiting rod 307 inside the through hole 306 connects the first rod body 301 to the second... The length between the rods 303 is adjusted. After adjustment, release the lever so that the limiting rod 307 is fixed inside the limiting hole 302 under the action of the spring 304. Place the bracket on the ground so that the moving wheel 402 contacts the ground, thereby achieving quick positioning of the bracket. When the bracket needs to be fixed here for a long time, loosen the second bolt 406 inside the second screw hole 404 and the third screw hole 407, move the slider 408 up inside the slide groove 403, and re-embed it inside the second screw hole 404 for fixation, so that the cone block 405 contacts the ground, thereby improving the stability of the bracket.
