DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a construction measurement device. Figure 1-4 A construction measurement device comprises a column 1, a mounting seat 2 for mounting a total station is fixedly connected to the top outer wall of the column 1, a movable ring 3 is sleeved on the outer wall of the column 1, a plurality of hinged seats 301 are fixedly connected to the outer wall of the movable ring 3, a support leg 4 is rotatably connected to the outer wall of the hinged seat 301, a plurality of support legs 4 are evenly distributed on the outer wall of the movable ring 3 in an equidistant circular array, a movable rod 5 is slidably connected to the inner wall of the support leg 4, a plurality of first connecting members 6 are fixedly connected to the outer wall of the column 1 near the bottom end, a connecting rod 601 is rotatably connected to the first connecting member 6, a second connecting member 602 is fixedly connected to the outer wall of the supporting leg 4 facing the column 1, an end of the connecting rod 601 away from the first connecting member 6 is hinged to the second connecting member 602, and an adjustment mechanism for driving the movable rod 5 to extend and retract is installed on the outer wall of the supporting leg 4;

[0023] The adjustment mechanism includes two first shaft seats 402 fixedly connected to the outer wall of the supporting leg 4, the inner walls of the two first shaft seats 402 are rotatably connected with a rotating shaft 403, the outer wall of the rotating shaft 403 located between the two first shaft seats 402 is fixedly connected with a gear 404, the outer wall of the movable rod 5 is provided with a plurality of tooth grooves 501, the outer wall of the supporting leg 4 is provided with a sliding groove 401, and the gear 404 passes through the sliding groove 401 and meshes with the plurality of tooth grooves 501.

[0024] The adjustment mechanism also includes a worm 407 rotatably connected to the outer wall of the support leg 4 through two second shaft seats 406 . One end of the rotating shaft 403 passes through a first shaft seat 402 and is fixedly connected to a worm wheel 405 . The worm wheel 405 is meshed with the worm 407 .

[0025] A servo motor 408 is fixedly mounted on the outer side wall of the support leg 4 , and the output shaft end of the servo motor 408 passes through a second shaft seat 406 and is fixedly connected to one end of the worm 407 .

[0026] A limiting groove 101 is provided on the outer wall of the column 1, and a wear-resistant and anti-skid layer is provided on the inner wall of the limiting groove 101. A threaded ring 302 is provided on the outer wall of the movable ring 3 corresponding to the limiting groove 101, and a locking bolt 303 is threadedly connected to the inner wall of the threaded ring 302. One end of the locking bolt 303 facing the column 1 is against the inner wall of the limiting groove 101.

[0027] The outer wall of the movable rod 5 near the top is fixedly connected with a tooth groove 501, and the tooth groove 501 is slidably connected to the inner wall of the slide groove 401. Through the sliding cooperation between the slider 502 and the slide groove 401, the movable rod 5 can be limited inside the supporting leg 4 to prevent the supporting leg 4 from detaching from the movable rod 5.

[0028] The implementation principle of a construction measurement device in the embodiment of the present application is as follows: in actual application, the total station is installed on the mounting seat 2, and the movable ring 3 is slid downward, so that the movable ring 3 pushes the multiple hinged seats 301 downward, and when the multiple hinged seats 301 push the support legs 4, the support legs 4 rotate around the hinged seats 301. When the support legs 4 rotate, they will also rotate at the end of the connecting rod 601 through the second connecting member 602, and the multiple connecting rods 601 move away from each other toward one end of the support legs 4, and perform an expansion movement to push the multiple support legs 4 outward, so that the bottom ends of the multiple support legs 4 are opened to form a stable tripod, and then the locking bolt 303 is rotated to make the locking bolt 303 rotate on the inner wall of the threaded ring 302, and the threaded ring 302 drives the end of the hinged seat 301 to press against the limiting groove 101, so that the position of the movable ring 3 can be locked and fixed, and at this time, the multiple support legs 4 are also fixed;

[0029] When the terrain measured by the total station is bumpy, the servo motor 408 is started through the adjustment mechanism on the multiple support legs 4, and the output shaft of the servo motor 408 drives the worm 407 to rotate on the inner walls of the two second shaft seats 406. At this time, the worm 407 can drive the worm wheel 405 meshing with it to rotate, and the worm wheel 405 can drive the gear 404 to rotate through the rotating shaft 403. When the gear 404 rotates, it will drive the multiple tooth grooves 501 meshing with it to move, and the movable rod 5 is driven to slide on the inner wall of the support leg 4 through the tooth groove 501, so that the overall length of a single support leg 4 and the movable rod 5 can be quickly adjusted, so that the device can lengthen or shorten each support leg 4 according to different terrains, so that the measuring device can be kept in a horizontal state, and the measurement accuracy is improved;

[0030] When it is necessary to adjust the height of the mounting base 2, the locking bolt 303 is rotated in the opposite direction to release the fixation of the movable ring 3, so that the movable ring 3 can slide up and down on the outer wall of the column 1. When the movable ring 3 slides downward, the column 1 drives the mounting base 2 to rise, and when the movable ring 3 slides upward, the column 1 drives the mounting base 2 to descend. After the height is adjusted, the locking bolt 303 can be tightened again to fix the movable ring 3, so that the height position of the column 1 can be fixed, thereby facilitating the adjustment of the measurement height of the total station.
