Description

Technical Field

[0001] The present application relates to the technical field of total stations, and in particular to a total station bracket. Background Art

[0002] A total station, or total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is a surveying and mapping instrument system that combines horizontal angle, vertical angle, distance (slant distance, horizontal distance), and elevation measurement. Compared to an optical theodolite, an electronic theodolite replaces the optical scale with a photoelectric scanning scale and replaces manual optical micrometer readings with automatic recording and display of readings, simplifying angle measurement and preventing reading errors. Because the instrument can complete all measurements at the station with a single setup, it is called a total station. It is widely used in precision engineering surveys or deformation monitoring, such as large-scale above-ground buildings and underground tunnel construction. During use, a total station requires support and placement on a stand.

[0003] The related art includes a support platform with a cavity and three support legs hingedly mounted on the bottom of the support platform. A placement platform for placing a total station is provided above the support platform. A lifting assembly for driving the placement platform up and down is provided between the placement platform and the support platform. The lifting assembly includes a drive gear that rotates in the cavity and a lifting gear plate that meshes with the drive gear. The upper and lower surfaces of the support platform are provided with through-holes that are in the same vertical line. The top of the lifting gear plate is fixedly connected to the bottom surface of the placement platform and passes downward through the support platform. The drive gear is connected to a drive member outside the support platform to control the rotation of the drive gear. The driving member drives the internal drive gear of the support platform to change the height position of the placement platform, thereby achieving the adjustment of the height of the total station placed on the placement platform.

[0004] However, when placing the stand, workers generally need to rotate the three support legs in sequence to open them to a certain angle in order to secure the stand. However, when adjusting the support legs, the three support legs cannot be adjusted simultaneously, resulting in a long adjustment time for the stand. This makes it inconvenient to place and use the total station, reducing the efficiency of the total station. Therefore, those skilled in the art have provided a total station stand to solve the problems raised in the above background technology. Utility Model Content

[0031] A lifting assembly 7 is provided inside the first vertical rod 5 and is connected to the second vertical rod 6 to drive the second vertical rod 6 to move up and down;

[0032] The limiting assembly 8 is arranged inside the first vertical rod 5 , and the limiting assembly 8 is slidably connected to the second vertical rod 6 to support the movement of the second vertical rod 6 .

[0033] In this embodiment, when the bracket needs to be placed, the movement of the lifting assembly 7 drives the second vertical rod 6 to move downward, and the second vertical rod 6 drives the triangle plate 3 to move downward. The triangle plate 3 pushes the three support legs 2 to rotate synchronously through the three connecting rods 4, so that the three support legs 2 are opened outward at the same time, and the bracket can be placed and fixed. The support legs 2 are telescopic rods, and their length can be adjusted as needed, so that the total station 9 can be placed and used. When the bracket needs to be stored, the reverse movement of the lifting assembly 7 drives the second vertical rod 6 to move upward, and the second vertical rod 6 drives the triangle plate 3 to move upward. The triangle plate 3 pulls the support legs 2 inward through the connecting rod 4, and the support legs 2 can be folded up, thereby facilitating the placement of the bracket, facilitating the use of the total station 9, and improving the use efficiency of the total station 9.

[0037] In this embodiment, when the first screw rod 73 drives the second vertical rod 6 to move up and down, the second vertical rod 6 drives the limit block 81 to slide in the limit groove 82. With the cooperation of the limit block 81 and the limit groove 82, the second vertical rod 6 can be auxiliary limited and supported to prevent the second vertical rod 6 from rotating, thereby facilitating the stable up and down movement of the second vertical rod 6.
