[0001] This utility model relates to the field of total station technology, and more specifically, to a total station fall protection device. Background Technology

[0002] A total station, also known as a total station electronic tachometer, is an instrument that, once observed at a station, automatically displays necessary data such as slope distance, zenith distance, and horizontal angle, and provides horizontal distance, elevation difference, and point coordinates almost simultaneously. By connecting the data terminal of the total station's field data collection to a computer and plotter via a transmission interface, and using data processing and plotting software, mapping can be automated.

[0003] A search revealed that utility model patent CN218378408U discloses a total station fall protection device, comprising: a fixed plate and three sliding rods, with support rods at the bottom of the sliding rods; a total station body disposed in the middle of the upper surface of the fixed plate; a protective mechanism disposed on the fixed plate, the protective mechanism including a connecting groove, multiple connecting rods, multiple tension springs, multiple support rods, and multiple limiting rods, the multiple connecting rods being slidably connected to the inner cavity of the connecting groove, the support rods being slidably connected to the inner cavity of the connecting rods, the tension springs being disposed below the support rods, the limiting rods being fixed between two adjacent connecting rods, and protective blocks being fixedly connected to the top of the multiple support rods; this patent utilizes the coordinated arrangement of the fixed plate, the protective mechanism, and the protective blocks to protect the outer wall of the total station body when it tilts, reducing the contact between the total station body and the ground and improving the protection of the total station body. However, the aforementioned patents have the following shortcomings: the total station body needs to rotate during use, and although the protective mechanism can also rotate to avoid obstructing the total station body, it requires separate operation, which is inconvenient; in addition, it is not convenient to protect the top of the total station, affecting the protective effect. Therefore, we propose a total station fall protection device. Utility Model Content

[0033] For details, please refer to Figure 3 and Figure 4 The side of the arc-shaped telescopic plate 7 fits against the inner wall of the telescopic groove 5.

[0034] In this embodiment, the stability of the arc-shaped telescopic plate 7 moving up and down within the telescopic groove 5 is ensured.

[0035] For details, please refer to Figure 6 The side of the square column 13 fits against the inner wall of the telescopic box 11.

[0036] In this embodiment, the inner wall of the telescopic box 11 is used to limit the square column 13, so that the square column 13 can only move along the axial direction of the screw 12.

[0037] Working principle: In use, first install the total station body 2 on the fixed plate 1, and insert the bottom ends of the two arc-shaped frames 4 connected by the connecting frame 10 into the inner cavity of the rotating groove 3 from the placement groove 20, so that the two arc-shaped frames 4 slide to one side of the fixed plate 1. Then, insert the bottom ends of the two arc-shaped frames 4 connected by the other connecting frame 10 into the inner cavity of the rotating groove 3 from the placement groove 20. Then, place the top cover 17 on top of the four support seats 8, and insert the bolts 19 into the mounting holes 18 on the top cover 17, so that the bottom ends of the bolts 19 are threaded into the screw holes 16 on the top surface of the support seats 8. Then, align the two connecting frames 10 with the two sides of the total station body 2. On the side, rotating the two turntables 15 drives the two screws 12 to rotate. Through the threaded engagement between the screws 12 and the square column 13, the square column 13 and the rubber pad 14 move towards the total station body 2, so that the end face of the rubber pad 14 fits against the side of the total station body 2. Finally, the arc frame 4, arc telescopic plate 7, support base 8 and top cover 17 are used to protect the side of the total station body 2 to prevent the total station body 2 from being damaged by impact when it tilts. At the same time, when the fixed plate 1 rotates, it drives multiple arc frames 4 to rotate synchronously, so that multiple arc frames 4 and multiple arc telescopic plates 7 do not obstruct the use of the fixed plate 1.
