Description

Technical Field

[0001] This utility model relates to the field of bus ring technology, and specifically to a leveling device and leveling system for bus ring installation. Background Technology

[0002] The bus ring is a crucial component of a radar system, primarily serving as a key element for power and signal transmission in the rotating radar system. The bus ring ensures continuous power and signal transmission between the stationary and rotating parts of the radar during rotation, guaranteeing normal operation. A typical bus ring consists of an upper base plate, a lower base plate, a conductive ring, and a brush assembly. High precision is required for the bus ring's levelness and coaxiality during installation. If these requirements are not met, the bus ring will become misaligned, causing it to scrape against the inner wall of the turntable during rotation and resulting in damage.

[0003] The current installation method for bus rings involves manually observing coaxiality by rotating a turntable with the naked eye, and adjusting the coaxiality based on feeling and experience. This method has large measurement errors and poses safety hazards. Furthermore, rotating the turntable requires at least four people, which is time-consuming and labor-intensive. The space inside the turntable is limited; after installing the bus ring, the operating space is only 20cm, making wiring and cable connection difficult. Utility Model Content

[0041] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0044] Figure 1 This is a schematic diagram of a leveling device according to one embodiment of the present invention. Figure 2 This is according to one embodiment of the present invention. Figure 1 A partial view, Figure 3 This is a schematic diagram of a partial structure of a leveling device according to one embodiment of the present invention. In this figure, the leveling device includes a steel ruler 1, a positioning shaft 2, a level assembly 3, and a dial indicator assembly 4. The steel ruler 1 is disposed inside the cylindrical hole 7 of the turntable 5, and located inside the annular groove 9 of the annular plate 8 within the cylindrical hole 7. Both ends of the steel ruler 1 are in contact with the inner wall of the annular groove 9. The positioning shaft 2 is disposed on the lower surface of the steel ruler 1 and is used to limit the movement of the top opening of the manifold 6. The level assembly 3 is disposed on the upper surface of the steel ruler 1, and the dial indicator assembly 4 is disposed at one end of the steel ruler 1, used to measure the coaxiality of the manifold 6 and the cylindrical hole 7 when the positioning shaft 2 rotates. The positioning shaft 2 is matched with the top opening of the busbar ring 6 for positioning and limiting. The position of the busbar ring 6 is adjusted by the level instrument assembly 3 until the busbar ring 6 and the turntable 5 are relatively horizontal. Then, the steel ruler 1 is rotated around the positioning shaft 2. The dial indicator assembly 4 is used to measure the coaxiality between the cylindrical hole 7 and the busbar ring 6 and further adjust the position of the busbar ring 6, thus achieving high-precision adjustment of the busbar ring 6 installation.

[0045] Compared with existing technologies, this utility model changes the measurement method of the bus ring 6 by visual inspection, improves the accuracy of coaxiality and levelness measurements, and ensures the installation quality of the bus ring 6. In one example of this utility model, for such Figure 3 The busbar ring 6 shown requires at least four people to operate while simultaneously rotating the turntable 5, which is time-consuming and labor-intensive. Furthermore, the space inside the turntable 5 is limited; after installing the busbar ring 6, the operating space is only 20cm, making cable wiring and connection difficult. This invention allows for pre-laying of cables, placing excess cable on both sides of the turntable 5 before installing and adjusting the busbar ring 6. Without the busbar ring 6 installed, there is ample space for cable laying, reducing the difficulty of cable laying and allowing for pre-laying, thus minimizing waiting time.

[0046] Before using the dial indicator assembly 4 to fine-tune the coaxiality of the busbar 6 and the cylindrical hole 7 of the turntable 5, a steel ruler 1 can be used to coarsely adjust the coaxiality of the busbar 6 and the cylindrical hole 7. Specifically, in this embodiment, the upper surface edge of the steel ruler 1 is provided with scale values. After the positioning shaft 2 is engaged and limited by the top opening of the busbar 6, the scale values ​​at both ends of the steel ruler 1 are read to ensure that the scale values ​​at both ends of the steel ruler 1 are consistent, and the busbar 6 is coarsely adjusted to the center position of the cylindrical hole 7.

[0047] Furthermore, to facilitate operators in reading the scale values ​​at both ends of the steel ruler 1, the scale values ​​increase at equal intervals from the center of the steel ruler 1 towards both ends.

[0048] In this embodiment, the method of installing the level 11 can be one of several known to those skilled in the art. In one example of this invention, such as... Figure 4 As shown, the level assembly 3 includes a first mounting platform 10 and a level 11. The first mounting platform 10 is disposed on the upper surface of the steel ruler 1, and the level 11 is placed on the first mounting platform 10. By adjusting the manifold 6 until the bubble in the level 11 is in the center position, it can be ensured that the manifold 6 is relatively horizontal in the cylindrical hole 7.

[0049] In this embodiment, the method of installing the dial indicator 13 can be one of several known to those skilled in the art. In one example of this invention, such as... Figure 4 As shown, the dial indicator assembly 4 includes a first mounting platform 10 and a dial indicator 13. The second mounting platform 12 is connected to the end of the steel ruler 1, and the probe of the dial indicator 13 abuts against the inner wall of the ring plate 8. If the cylindrical hole 7 and the manifold 6 are not coaxial, when the steel ruler 1 rotates around the positioning shaft 2, the pointer of the dial indicator 13 will swing; the difference between the maximum and minimum swing values ​​is the coaxiality error.

[0050] In this embodiment, the specifications of the dial indicator 13 can be of various types known to those skilled in the art. In one example of this invention, the smallest graduation of the dial indicator 13 is 0.02 mm. When adjusting the bus ring 6, adjusting the coaxiality error to less than 0.08 mm satisfies the adjustment requirements for the coaxiality of the bus ring 6 and the cylindrical hole 7.

[0051] In this embodiment, the mounting holes are connected to the positioning shaft 2, the level assembly 3, and the dial indicator assembly 4, respectively. The number of mounting holes can be multiple, as is known to those skilled in the art, such as 2 or 3. In one example of this invention, the number of mounting holes can be 3. Furthermore, the method of connecting the positioning shaft 2, the level assembly 3, and the dial indicator assembly 4 to the mounting holes can be various, as is known to those skilled in the art, including snap-fit ​​and bolt connection. In one example of this invention, the mounting holes are connected to the positioning shaft 2, the level assembly 3, and the dial indicator assembly 4 via bolt connections.

[0052] On the other hand, this utility model provides a leveling system, such as Figure 3 As shown, the leveling system includes a turntable 5, a manifold ring 6, and a leveling device as described above. The turntable 5 has a cylindrical hole 7. The manifold ring 6 is installed inside the cylindrical hole 7, and the leveling device is used to adjust the horizontality of the manifold ring 6 and its coaxiality with the cylindrical hole 7.

[0053] In this embodiment, the specific structure of the turntable 5 can be of various types known to those skilled in the art. In one example of this invention, to support the leveling device, an annular plate 8 is provided on the inner wall of the cylindrical hole 7 of the turntable 5. The upper surface of the annular plate 8 is in contact with the lower surface of the leveling device so that the leveling device can rotate within the cylindrical hole 7.

[0054] Furthermore, the ring plate 8 is provided with a ring groove 9, the inner wall of which fits against the leveling device to provide support for the leveling device.

[0055] Through the above technical solution, this utility model provides a leveling device and system for bus ring installation. The device uses a positioning shaft that engages with the top opening of the bus ring for positioning. A leveling instrument assembly is used to adjust the bus ring's levelness. First, a steel ruler is used to coarsely adjust the coaxiality between the bus ring and the cylindrical hole of the turntable. Then, a dial indicator assembly is used for fine-tuning the coaxiality. Compared with existing technologies, this utility model improves the accuracy of coaxiality and levelness measurements, ensuring the installation quality of the bus ring. Furthermore, cable laying can be completed before adjusting the bus ring position, reducing the difficulty of cable laying.
