Description

Technical Field

[0001] This utility model relates to the collimation of an accelerator in a free electron laser device, and more specifically to an eccentric centering device for a total station. Background Technology

[0002] The free-electron laser device is installed inside a narrow and long tunnel. The accelerator section is the key part of the entire device, primarily responsible for boosting electron energy. Extremely high positioning accuracy is required during installation. Therefore, it is necessary to control and measure the tunnel's control network. Establishing a collimation control network for the entire device serves as the installation benchmark, guiding on-site installation work and ensuring the required installation precision.

[0003] Due to space constraints in the installation of the equipment, the collimation control network can only be deployed on the left side of the tunnel surface and at the central torsion leg support. However, both sides of the torsion leg support are covered by movable floor panels, making them highly susceptible to displacement due to the activities of personnel on site. Commonly used measuring supports for control network surveying cannot stably support the total station within the existing tunnel surface structure, as the ground environment increases the instability of the measuring instrument and reduces its accuracy. Utility Model Content

[0023] The preferred embodiments of this utility model are given below with reference to the accompanying drawings and described in detail.

[0024] In this utility model, the directions of X, Y, and Z are as follows: Figure 1A As shown, the first side in each direction is Figure 1A The second side of each direction indicated by the arrows in the coordinate system is... Figure 1A The opposite direction pointed to by the arrow in the coordinate system.

[0025] like Figure 1A and Figure 1B As shown, the eccentric centering device for a total station according to this utility model includes a first support 100, a second support 200, and a third support 300. The first support 100 is located at the bottom of the device, directly contacting the ground and supporting the entire device. The second support 200 is located in the middle, connecting the first support 100 and the third support 300, improving the overall stability of the device. The third support 300 is located at the top and is used to mount the two-dimensional moving platform of the total station.

[0026] like Figure 1AAs shown, the first support 100 includes a first plate 101 and an eccentric counterweight 110. The first plate 101, as the main structural component of the first support 100, is a triangular plate extending in the XY plane, providing a mounting base for the eccentric counterweight 110 and other components. It possesses sufficient strength and stability to support the weight of the entire device. The eccentric counterweight 110 is fixedly connected to the first plate 101 on the Z-direction and X-direction first sides, adjacent to a vertex of the triangular plate, via a first bolt assembly 111. This assembly is used to adjust the center of gravity of the device, ensuring its stability and balance during measurement. Specifically, the eccentric counterweight 110 is fixed to the first plate 101 on the X-direction first side, ensuring that when the total station is installed on the third support 300, the center of gravity of the entire device is located at the center of the device, preventing tipping under stress. In this embodiment, the first bolt assembly 111 includes four first bolts arranged on the Z-direction first side, each bolt being threadedly connected to the eccentric counterweight 110 and the first plate 101.

[0027] like Figure 1A As shown, the first bracket 100 also includes three universal feet 120, which are respectively fixedly connected near the three vertices of the first plate 101. Figure 2A As shown, three first threaded through holes 123 are respectively provided near the three vertices of the first plate 101. Each universal joint 120 includes a screw 121 and a base 122 fixedly connected to the bottom of the screw 121. The screw 121 extends through the first threaded through hole 123, and the base 122 is located on the second Z-direction side of the first plate 101 and contacts the ground. By adjusting the length of the screw 121, the base 122 can be made to contact the ground. The universal joint 120 allows the base 122 to automatically adjust to the optimal contact angle on uneven ground. For example, if one side of the ground is higher, the base 122 of the universal joint will automatically tilt to ensure the maximum contact area with the ground. This automatic balancing mechanism allows the universal joint to provide stable support on uneven ground, thereby ensuring the stability of the entire device. In this way, the universal joint 120 enables the total station's eccentric centering device to be set up at any location within the accelerator tunnel.

[0028] like Figure 1A , Figure 1B and Figure 2BAs shown, the first support 100 also includes three caster wheel assemblies 130, each fixedly connected to the second Z-direction side of the first plate 101. The caster wheel assemblies 130 are mounted on the bottom edge of the first plate 101, but not at a corner, rather between two adjacent caster feet 120, which helps to evenly distribute the weight of the device and provides better support and mobility. The second Z-direction side of the first plate 101 has three threaded holes, and each caster wheel assembly 130 includes an independently rotatable caster wheel. The caster wheel is connected to the first plate 101 through the threaded holes, allowing the device to move flexibly within tunnels or other working areas.

[0029] like Figure 1A As shown, the first support 100 also includes a first viewing hole 140 and a first support structure 150. The first viewing hole 140 penetrates the first plate 101 on the second side in the X direction to ensure the continuity and accuracy of the measurement line of sight. The first support structure 150 is connected to the first side in the Z direction of the first plate 101 around the first viewing hole 140, extends to the first side in the Z direction, and connects to the second side in the Z direction of the second support 200. In this embodiment, the center of the line connecting the two universal feet 120 on the second side in the X direction of the first plate 101 coincides with the center of the first viewing hole 140 in the XY direction. In this embodiment, the first support structure 150 consists of three vertical rods, which are evenly spaced at 120° and arranged in parallel around the first viewing hole 140 to provide stable support.

[0030] like Figure 1A and Figure 3 As shown, the second support 200 includes a second plate 201, a second viewing hole 210, and a second support structure 220. The second plate 201, as the main structural component of the second support 200, is a circular plate extending in the XY plane. The second viewing hole 210 is located at the center of the second plate 201 and is a through hole coaxial with the center of the first viewing hole 140 (parallel to the Z-direction), ensuring the continuity of the measurement line of sight. The second support structure 220 surrounds the second viewing hole 210 and connects to the first Z-direction side of the second plate 201, extending to connect to the second Z-direction side of the third support 300. In this embodiment, the second support structure 220 consists of three vertical rods, which are evenly spaced at 120° intervals and arranged parallel to each other, surrounding the second viewing hole 210 to provide stable support. It should be understood that the main function of the second support 200 is to connect the first support 100 and the third support 300. The splicing method avoids the lack of stability of a single excessively long vertical bar. At the same time, the three vertical bars provide sufficient support, avoiding additional increases in processing costs and support weight.

[0031] like Figure 1A and Figure 4As shown, the third support 300 includes a third plate 301 and a third viewing hole 310. The third plate 301, as the main structural component of the third support 300, is a circular plate extending in the XY plane. The third viewing hole 310 is located at the center of the third plate 301 and is a through hole coaxial (parallel to the Z-direction) with the centers of the first viewing hole 140 and the second viewing hole 210, ensuring the continuity of the measurement line of sight. In this embodiment, the diameter of the second viewing hole 210 is larger than the diameter of the first viewing hole 140, and the diameter of the first viewing hole 140 is larger than the diameter of the third viewing hole 310. It should be understood that the second plate 201 is mainly used to provide stability for the support rod without obstructing the line of sight, and the second viewing hole 210 is mainly used to reduce the weight of the second plate 201. In addition, the third support 300 also includes four second threaded through holes 320, which are distributed around the third viewing hole 310. The screw bolt structure passing through the second threaded through holes 320 connects the third plate 301 and the two-dimensional moving platform of the total station, so as to realize the fixation and centering operation of the total station.

[0032] According to the eccentric centering device of the total station of this utility model, the eccentric structure of the device (eccentric counterweight 110), the fixed position of the device (universal feet 120), and the movement (universal wheel assembly 130) are achieved through the first support 100. The upper and lower parts of the device are connected by the second support 200 to improve stability. The two-dimensional moving platform is installed by the third support 300 to achieve the centering of the total station. When measuring control points in a tunnel, the three universal feet 120 can be placed on three unstable or unstable ground structures at the same time, leaving a movable cover on one side for the movement of personnel or vehicles. This ensures that the measuring instrument will not shake due to the movement of personnel or vehicles or slight vibrations, thus avoiding affecting the measurement accuracy of the total station. In addition, this design also allows the total station to provide a passageway on one side for the surveyor to stand, avoiding the shaking of the equipment when the surveyor stands on the ground during instrument leveling, measurement, and station changing, thereby meeting the requirements of the total station's measurement environment and improving measurement accuracy.

Various variations can be made to the above embodiments of this utility model. That is, all simple and equivalent changes and modifications made based on the claims and description of this utility model application fall within the protection scope of the claims of this utility model patent.
