Description

Technical Field

[0001] This utility model relates to the field of total station auxiliary equipment technology, specifically a total station auxiliary aiming device for topographic surveying. Background Technology

[0002] In the process of topographic surveying, a total station is needed to measure the terrain and prominent features such as ridges and valleys. During the measurement process, the prism is placed on the surveyed terrain, and then the total station is used to locate the prism. In order to facilitate the location of the prism, when the terrain is complex or the prism is far away, it is often necessary to use a total station auxiliary aiming device for topographic surveying.

[0003] According to the patent application CN218268174U, "A total station auxiliary aiming device for topographic surveying, relating to the field of total station auxiliary equipment technology, has two positioning plates, an alignment mechanism installed between the two positioning plates, and a clamping mechanism installed on the fixed end of the alignment mechanism. A small monocular telescope is connected in contact within the clamping mechanism, and the position of the central axis of the alignment mechanism coincides with the position of the central axis of the positioning plate. The total station auxiliary aiming device for topographic surveying described in this utility model adjusts the position of the total station auxiliary aiming device on the lens of the total station through the alignment mechanism, so that the central axis of the total station auxiliary aiming device corresponds to the central axis of the lens of the total station. The total station auxiliary aiming device is fixed on the lens of the total station by a suction cup, so that the orientation of the small monocular telescope is the same as the orientation of the lens of the total station, which facilitates the staff to find the prism."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model involves placing the auxiliary aiming device for a total station used for topographic surveying onto the lens of the total station. Pulling the two first connecting rods to both sides positions the coarse aiming device on the lens between the two connecting rods. The operator then rotates a dial, which in turn drives a gear through a rotating rod. However, in actual use, because the device only uses a suction cup to limit the movement between the device and the total station, and because the total station is used outdoors in high temperatures or strong winds, the device is prone to detaching from the total station. Furthermore, since the device is manually installed, the monocular telescope and the total station's observation position may not be on the same horizontal plane, affecting the observation results. Therefore, an improved auxiliary aiming device for a total station used for topographic surveying is needed to solve these problems. Utility Model Content

[0034] Furthermore, the movable plate 412 is threadedly connected to the bidirectional threaded rod 411, and the connecting platform 1 is provided with a groove at the corresponding position of the movable plate 412, and the movable plate 412 is slidably connected inside the groove, which facilitates the adjustment of the position of the clamping block 413, thereby satisfying the clamping and limiting installation of total stations of different sizes.

[0035] Furthermore, there are two clamping blocks 413, and the two clamping blocks 413 are symmetrically distributed with the center line of the front of the connecting platform 1 as the axis of symmetry, which makes the installation process more stable.

[0036] Furthermore, the adjustment assembly 42 includes an adjustment box 421, which is fixedly connected to the top of the connecting platform 1. A connecting column 422 is movably connected inside the adjustment box 421, and a handle 423 is fixedly connected to the outside of the connecting column 422.

[0038] Example 2:

[0039] Based on Embodiment 1, the existing device is manually installed by staff, which can easily lead to the monocular telescope and total station observation positions not being on the same horizontal plane, thus affecting the observation results. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6-7 Furthermore, in conjunction with Embodiment 1, the movable clamping mechanism 5 includes a mounting platform 51, which is fixedly connected to the top of the connecting column 422.

After installation, the operator places the monocular telescope 2 on top of the mounting platform 51. The operator then rotates the worm gear 52. The rotation of the worm gear 52 causes the worm wheel 54 to rotate, thereby moving the limiting plate 512. 5. Rotate the slider 57 to slide inside the guide rail 56, thereby adjusting the position of the clamping plate 53. After installation, the operator presses the handle 423. The movement of the handle 423 causes the connecting column 422 to move, which in turn causes the second limiting plate 425 to move. In conjunction with the spring 427, the support plate 426 moves, which in turn moves the first limiting plate 424. After pressing, rotate the handle 423 to adjust the angle of the monocular telescope 2. After adjustment, release the handle 423.
