Description

Technical Field

[0001] This utility model relates to accelerator collimation, and more specifically to a two-dimensional moving platform device for a total station. Background Technology

[0002] The accelerator equipment is installed inside a long linear accelerator tunnel, requiring extremely high collimation accuracy to ensure the smooth movement of particles within the orbit. Therefore, the accelerator equipment needs to be collimated and positioned to its theoretical design location with high precision, and the higher the absolute accuracy, the better. This necessitates the establishment of a high-precision collimation control network.

[0003] In accelerator engineering, laser trackers and total stations are among the most widely used measuring instruments. Typically, laser trackers are used to establish tunnel control networks through free station setup and overlapping measurements. However, this method is prone to distortion and deformation of the control network when measuring long-distance tunnels.

[0004] To solve this problem, it is necessary to rely on the advantages of total station long-distance measurement to establish a tunnel backbone network, thereby constraining the control network measured by laser tracker and reducing the phenomenon of bending in the middle or "tailing" at the end of the control network.

[0005] Accelerator control network measurement falls under the category of precision engineering measurement. When establishing a backbone network constraint control network using a total station, it is necessary to use a high-precision total station and to center the total station precisely on the control points in order to reduce the control network measurement error caused by the centering of the control points.

[0006] However, the current total station centering method involves moving the tripod of the total station for centering. This method has centering errors and cannot meet the requirements of high-precision centering, thus reducing the measurement accuracy of the total station. Utility Model Content

[0007] To address the issues of centering errors in the prior art, this invention provides a two-dimensional moving platform device for a total station.

[0008] The two-dimensional moving platform device for a total station according to this utility model includes a first sliding table structure, a second sliding table structure, a mounting base, a base, a first bolt adjusting assembly, and a second bolt adjusting assembly. The base is fixedly mounted on a centering device. The first sliding table structure is provided by a first outer dovetail groove and a first inner dovetail groove that slide in the X direction. The second sliding table structure is provided by a second inner dovetail groove and a second outer dovetail groove that slide in the Y direction. The mounting base is movably mounted on the base via the first and second sliding table structures. The total station is mounted on the mounting base.

[0012] In a preferred embodiment, the second bolt adjusting assembly is connected to the connecting block to adjust the position of the connecting block and the total station on it in the Y direction.

[0013] In a preferred embodiment, the second bolt adjusting assembly includes two second adjusting members disposed opposite each other in the Y direction.

[0019] Figure 1 This is a schematic diagram of the overall structure of a two-dimensional moving platform device for a total station according to a preferred embodiment of the present invention.

[0020] Figure 2 yes Figure 1 A bottom view. Detailed Implementation

[0021] The preferred embodiments of this utility model are given below with reference to the accompanying drawings and described in detail.

[0022] In this utility model, the directions of X, Y, and Z are as follows: Figure 1 As shown.

[0023] like Figure 1 As shown, the two-dimensional moving platform device for the total station of this utility model includes a first sliding table structure 100, a second sliding table structure 200, a mounting base 300, and a base 400. The base 400 is fixedly installed on the centering device, providing a stable support foundation for the entire device. The mounting base 300 is movably mounted on the base 400 via the first sliding table structure 100 and the second sliding table structure 200, and the total station is mounted on the mounting base 300. The first sliding table structure 100 is used to realize the movement of the total station in the X direction, and the second sliding table structure 200 is used to realize the movement of the total station in the Y direction. By precisely moving the total station in the X and Y directions through the first sliding table structure 100 and the second sliding table structure 200, it is ensured that the total station can accurately point to the ground control point, thereby providing high-precision measurement results.

[0024] The first slide structure 100 and the second slide structure 200 are formed from a single piece of material through integral cutting. Specifically, through the first and second cuts, the single piece of material is processed into three solid blocks: a base block, an intermediate block, and a connecting block. The base block is fixedly mounted on the base 400, while the mounting base 300 is fixedly mounted on the connecting block. The direction of the first cut is perpendicular to the direction of the second cut. The first cut forms a first outer dovetail groove 110 on the upper surface of the base block and a first inner dovetail groove 120 on the lower surface of the intermediate block. The second cut forms a second inner dovetail groove 210 on the upper surface of the intermediate block and a second outer dovetail groove 220 on the lower surface of the connecting block. Through this cutting method, the first outer dovetail groove 110 and the first inner dovetail groove 120 cooperate to form the first slide structure 100, while the second inner dovetail groove 210 and the second outer dovetail groove 220 cooperate to form the second slide structure 200. In a preferred embodiment, the single piece of material is 304 stainless steel. In a preferred embodiment, the slope angle of the dovetail grooves 110, 120, 210, and 220 is between 30° and 60°, more preferably 45°. In a preferred embodiment, the groove depth of the dovetail grooves 110, 120, 210, and 220 is between 10mm and 20mm, more preferably 15mm. In a preferred embodiment, the groove width of the inner dovetail grooves 120 and 210 is between 100mm and 200mm, more preferably 150mm.

[0025] Mounting base 300 includes a base 310 and a threaded interface 320, wherein the base 310 is connected to the connecting block via a first bolt structure 311. In a preferred embodiment, the first bolt structure 311 includes four countersunk threaded holes, each of which is connected to the connecting block and the base 310 via a countersunk bolt, thereby avoiding interference between the bolt structure and the total station when installing the total station.

[0026] The base 400 has four threaded through holes 410 at its four corners. Each threaded through hole 410 is fixedly connected to the two-dimensional moving platform device and the centering device through a bolt structure.

[0027] like Figure 1As shown, the two-dimensional moving platform device for the total station of this utility model also includes a first bolt adjusting assembly 500 fixedly installed on the base 400. The first bolt adjusting assembly 500 is connected to the intermediate block and is used to adjust the position of the intermediate block, the connecting block, and the total station on them in the X direction. Specifically, the first outer dovetail groove 110 and the first inner dovetail groove 120 extend in the X direction. By pushing the first bolt adjusting assembly 500, the intermediate block moves relative to the base block in the X direction. Since the second inner dovetail groove 210 and the second outer dovetail groove 220 extend in the Y direction, the movement of the intermediate block will drive the connecting block to move synchronously in the X direction. This design allows the total station to be precisely adjusted in the X direction, thereby achieving precise alignment with the centering device.

[0028] The first bolt adjusting assembly 500 includes two first adjusting members 501 and 502 arranged opposite each other in the X direction. Each first adjusting member 501 and 502 includes a first adjusting block 510 and 520, a first adjusting screw 511 and 521, a first fixing nut 512 and 522, and two first fixing bolts 513 and 523. The first adjusting blocks 510 and 520 are fixedly connected to the base 400 by the two first fixing bolts 513 and 523. The first adjusting screws 511 and 521 are threaded onto the first adjusting blocks 510 and 520, and the first adjusting screws 511 and 521 extend in the X direction and can be separably contacted with the intermediate block. By adjusting the first adjusting screws 511 and 521, the intermediate block can be moved in the X direction. After adjustment, tighten the first fixing nuts 512 and 522 to lock the first adjusting screws 511 and 521. This will fix the intermediate block in the desired position and prevent accidental rotation due to vibration, impact, or long-term load, thereby ensuring the positional accuracy of the total station in the X direction.

[0029] like Figure 1 As shown, the two-dimensional moving platform device for the total station of this invention also includes a second bolt adjustment assembly 600 fixedly mounted on the base 400. The second bolt adjustment assembly 600 is connected to the connecting block and is used to adjust the position of the connecting block and the total station on it in the Y direction. Specifically, the second inner dovetail groove 210 and the second outer dovetail groove 220 extend in the Y direction, and the connecting block moves relative to the intermediate block in the Y direction by pushing with the second bolt adjustment assembly 600. Since the first outer dovetail groove 110 and the first inner dovetail groove 120 extend in the X direction, the movement of the connecting block will not cause the intermediate block to move relative to the base block. This design allows the total station to be precisely adjusted in the Y direction, thereby achieving precise alignment with the centering device.

[0030] The second bolt adjusting assembly 600 includes two second adjusting members 601 and 602 arranged opposite each other in the Y direction. Each second adjusting member 601 and 602 includes a second adjusting block 610 and 620, a second adjusting screw 611 and 621, a second fixing nut 612 and 622, and two second fixing bolts 613 and 623. The second adjusting block 610 and 620 are fixedly connected to the base 400 by the two second fixing bolts 613 and 623. The second adjusting screw 611 and 621 are threadedly connected to the second adjusting block 610 and 620. The second adjusting screw 611 and 621 extend in the Y direction and can be separably contacted with the connecting block. By adjusting the second adjusting screw 611 and 621, the connecting block can be moved in the Y direction. After adjustment, tighten the second fixing nuts 612 and 622 to lock the second adjusting screws 611 and 621. This will fix the connecting block in the desired position and prevent accidental rotation due to vibration, impact, or long-term load, thereby ensuring the positional accuracy of the total station in the Y direction.

[0031] like Figure 2 As shown, the first slide structure 100, the second slide structure 200, and the mounting base 300 each have a circular through-hole inside. These circular through-holes ensure line-of-sight between the total station and the ground control point, thereby enabling high-precision setup and alignment of the total station with the ground control point. Specifically, the centers of the three circular through-holes are coaxial, their axes are parallel to the Z-direction, and are coaxial with the center of the through-hole reserved in the centering device, ensuring line-of-sight between the total station and the ground control point.

[0032] In actual operation, the total station is mounted on the mounting base 300. When the position of the total station needs to be adjusted, it is moved in the X and Y directions via the first sliding platform structure 100 and the second sliding platform structure 200. It should be understood that there is also an adjustable leveling base between the total station and the mounting base 300. This base allows the total station to be leveled. The bottom of the total station emits a downward-facing laser (the laser represents the center position of the total station). By adjusting the first sliding platform structure 100 and the second sliding platform structure 200, this laser can be aligned with the ground control point. During movement, the total station may tilt. In this case, the leveling base is used to level the total station again, and the above steps are repeated. That is, when the total station is level, it emits a laser perpendicular to the horizontal plane that coincides with the ground control point, thus achieving centering of the total station with the ground control point.

[0033] Thus, the two-dimensional moving platform device of the total station according to this utility model is connected to the centering device through the base 400, and the dovetail grooves 110, 120, 210, 220 combined with the feed screws 511, 521, 611, 621 realize translation in two directions. The mounting base 300 realizes the connection with the total station. The device has a reserved viewing hole to realize the line of sight between the total station and the centering control point, avoiding the need to simply move the tripod to achieve centering, thus ensuring the measurement accuracy of the total station.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. 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. Any aspects of this utility model not described in detail are conventional technical content.
