Technical Field

[0001] The utility model relates to the technical field of bridge surveying, in particular to a conveniently adjustable bridge surveying device for bridge engineering. Background Art

[0002] Bridge engineering refers to the process of bridge surveying, design, construction, maintenance, and verification, as well as the science and engineering technology that studies this process. It is a branch of civil engineering. Surveying is a general term for investigation, exploration, and measurement. Before construction, field surveys and measurements are conducted. When building a bridge, survey equipment is required to conduct field surveys. This ensures that the structure and design of the bridge are integrated with the geology of the site to ensure its stability.

[0003] However, when using bridge survey equipment for surveying, the survey instrument is usually placed on a bracket for use. When the height of the survey instrument needs to be adjusted, the height must be adjusted by adjusting the length of the bracket. In the process of raising or lowering the bracket, the center of gravity of the bracket is prone to change, affecting its stability. Therefore, how to solve this problem is what we need to consider.

The supporting legs 7 can be retracted through the receiving openings 8 when the equipment is not in use, and the side walls of each supporting leg 7 are elastically connected to the inner wall of the corresponding receiving opening 8 by a spring 9, the lower end of the slider 6 is fixedly connected to a moving rod 10, the lower end of the moving rod 10 extends to the outside, and the lower end of the moving rod 10 is fixedly connected to a counterweight block;

[0027] The downward movement of the slider 6 will drive the three support legs 7 to extend from the corresponding storage openings 8. Under the elastic action of the spring 9, the three support legs 7 are unfolded to stably support the surveying instrument 5, and the downward movement of the slider 6 will also cause the moving rod 10 to move down with the counterweight to support it, so as to prevent the surveying instrument 5 from tilting and collapsing due to external forces and affecting normal use. Plug holes 11 are provided on the inner walls of both sides of the base 1, and a sleeve 12 is rotatably connected to the inner wall of one of the plug holes 11. One end of the sleeve 12 is rotatably connected to the inner wall of the corresponding plug hole 11 through a bearing. A threaded rod 13 is connected to the inner thread of the sleeve 12. A plurality of limiting holes 14 cooperating with the threaded rod 13 are provided in the column 2. The other end of the threaded rod 13 passes through the corresponding limiting hole 14 and extends to another plug hole 11. By inserting the threaded rod 13 into different limiting holes 14, the height of the column 2 and thus the height of the surveying instrument 5 can be adjusted, which is convenient for different operators to use.

[0028] Among them, the outer wall of the base 1 is rotatably connected to the second shaft 15, and the sleeve 12 and the second shaft 15 are fixedly connected to a gear 16, and the two gears 16 are meshed. The other end of the second shaft 15 is fixedly connected to the first knob 17, and the outer wall of the first knob 17 is provided with a rubber layer. A rack 18 is provided on one side wall of the base 1, and the rack 18 is meshed with one of the gears 16. An opening 19 is opened on one side wall of the base 1, and a connecting rod 20 is fixedly connected to the side wall of the rack 18. The other end of the connecting rod 20 passes through the opening 19 , and is fixedly connected to the side wall of the slider 6. A worm gear 21 is fixedly connected to the outer wall of the first rotating shaft 4. Two mounting plates 22 are fixedly connected to the upper end of the fixed plate 3. A worm 23 is rotatably connected between the two mounting plates 22. The worm 23 is engaged with the worm gear 21. One end of the worm 23 passes through one of the mounting plates 22 and is fixedly connected to a second knob 24. The outer wall of the second knob 24 is provided with a rubber layer. By cooperating with the worm gear 21 and the worm 23, the angle of the surveying instrument 5 can be adjusted, so that surveying can be carried out in multiple directions.

[0029] In the present invention, when in use, the column 2 is inserted into the base 1, and then the first knob 17 is rotated to rotate the corresponding gear 16. The other gear 16 meshing with it also rotates to rotate the sleeve 12, thereby moving the threaded rod 13 threadedly connected to the sleeve 12. The threaded rod 13 passes through the limiting hole 14 on the column 2 and is inserted into the corresponding insertion hole 11, thereby achieving the fixed installation of the column 2. By inserting the threaded rod 13 into different limiting holes 14 on the column 2, the height of the column 2 and thus the height of the surveying instrument 5 can be adjusted, which makes it convenient for different operators to use.

[0030] During the above process, the rotation of the other gear 16 will also cause the rack 18 meshing with it to move downward, and the downward movement of the rack 18 will in turn cause the slider 6 to move downward through the connecting rod 20. During this process, the slider 6 will cause the three support legs 7 to extend from the corresponding receiving openings 8. Under the elastic action of the three springs 9, the three support legs 7 will unfold to support the surveying instrument 5, and the moving rod 10 will also move the counterweight block downward to provide support, so that the surveying instrument 5 can be stably supported to prevent the surveying instrument 5 from tilting and collapsing.

[0031] After the entire device is supported, the surveying instrument 5 can be used for surveying. When the angle needs to be adjusted during the surveying process, the second knob 24 can be turned to rotate the worm 23. The rotation of the worm 23 will rotate the worm gear 21 engaged with it. The worm gear 21 will rotate with the surveying instrument 5 through the first rotating shaft 4, and then the angle of the surveying instrument 5 can be adjusted, so that surveying can be carried out in multiple directions.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
