Description

Technical Field

[0001] This utility model relates to the field of busbar calibration technology, and in particular to a portable switch busbar connection calibration tool. Background Technology

[0002] Busbars are crucial conductors in power systems used for collecting, distributing, and transmitting electrical energy. They are typically made of copper or aluminum and installed in substations, distribution cabinets, and other equipment, serving as connection hubs between different electrical components. Their core function is to efficiently integrate the current path between the power source and the load, ensuring stable power transmission. The current-carrying capacity, mechanical strength, and insulation performance of the busbar directly affect system reliability. Therefore, factors such as voltage level, short-circuit current, and temperature rise must be comprehensively considered during design. During production, transportation, and storage, busbars may develop defective parts due to angular twisting or unevenness. These defective busbars must be corrected before they can be used normally.

[0003] A search revealed Chinese patent publication number CN217757696U, which discloses a horizontal busbar correction device for an aluminum electrolytic cell. The device includes a ground surface, a horizontal cover plate for four jacks, and an electrolytic cell crossbeam. Four jacks are placed above the ground surface, and the horizontal cover plate is engaged above each jack. The device also includes limiting rods located on the left and right sides of the electrolytic cell crossbeam, with the busbar body located inside the limiting rods.

[0004] To address the problems of using multiple jacks for fixing in the above-mentioned technologies, which are inconvenient to carry for adjusting the busbars of small distribution boxes, and the fact that the protruding parts of the busbars are prone to slippage and misalignment during adjustment, leading to adjustment failure, a portable switch busbar connection adjustment tool is proposed.

[0005] In view of this, the present invention aims to provide a portable switch bus connection calibration tool to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: A portable switch busbar connection calibration tool includes a mounting base with a top support plate installed on top. A translation plate is slidably connected to the inner side of the top support plate. A drive assembly is rotatably connected to the top of the translation plate. A calibration nut is rotatably connected to one end of the translation plate. A calibration screw is threadedly connected to the inner side of the calibration nut. Sliding rods are slidably connected to both sides of the calibration nut. The two ends of the sliding rods are fixedly connected to the two ends of the calibration screw. A buffer sleeve is slidably connected to the top of the mounting base. A buffer assembly is fixedly connected to the top of the buffer sleeve. An anti-deviation assembly is rotatably connected to the bottom of the calibration screw and the top of the buffer assembly.

[0007] In some embodiments, the anti-deviation assembly includes a pressing plate, a limiting plate, and a second spring. One end of the pressing plate is rotatably connected to one end of the correction screw or the buffer assembly, the limiting plate is rotatably connected to both ends of the pressing plate, and both ends of the second spring are fixedly connected to the rotatable connection between the pressing plate and the limiting plate.

[0008] In some embodiments, the buffer assembly includes a buffer sleeve, a spring, and a buffer rod. The buffer sleeve is fixedly connected to the top of the adjusting base, the buffer rod is slidably connected to the top of the buffer sleeve, and the top of the buffer sleeve is rotatably connected to the lower compression plate. The two ends of the spring are fixedly connected to the buffer rod and the adjusting base, respectively.

[0009] In some embodiments, the drive assembly includes an adjusting gear ring, a drive gear, and a drive sleeve. The adjusting gear ring and the drive gear are rotatably connected to a translation plate. The adjusting gear ring is fixedly connected to the outside of the correction nut. The adjusting gear ring and the drive gear mesh with each other. The drive sleeve is fixedly connected above the drive gear.

[0010] In some embodiments, the bottom of the adjusting base is threadedly connected to a translation screw, and both ends of the translation screw are rotatably connected to the inside of the mounting base.

[0011] In some embodiments, a plurality of movable brackets are slidably connected above the adjustment base, an adjustment screw is slidably connected to the inner side of the movable bracket, and a swing bracket is fixedly connected above the adjustment screw.

[0012] In some embodiments, an anti-deviation rod is slidably connected to the inner side of the adjusting screw, and an adjusting nut is threadedly connected to the outer side of the adjusting screw. The adjusting nut is rotatably connected to the upper end of the movable bracket, and the anti-deviation rod is fixedly connected to the inner side of the movable bracket.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] 1. A portable switch busbar connection calibration tool uses an electric wrench inserted into the hexagonal slot of the drive sleeve to rotate the drive gear, which in turn meshes with the adjusting gear ring to rotate the calibration nut. This drives the calibration screw to move up and down, squeezing the busbar for calibration. This simplifies the structure, avoids multiple hydraulic rods, reduces overall weight, and makes it easy to carry. Furthermore, the squeezing plate and limiting plate in the anti-deviation component are wrapped in rubber and rotate inward under the action of spring II, clamping the busbar above and below and restricting the busbar to be directly below the calibration screw. This prevents slippage caused by the smooth surface of the busbar and improves calibration accuracy.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-5 As shown, the portable switch busbar connection calibration tool includes a mounting base 1 with a top support plate 2 mounted on top. A sliding plate 3 is slidably connected to the inner side of the top support plate 2. The sliding plate 3 can move left and right to adjust the calibration position for busbars whose bends are not in the center. A drive assembly is rotatably connected to the top of the sliding plate 3. A calibration nut 6 is rotatably connected to one end of the sliding plate 3. A calibration screw 7 is threadedly connected to the inner side of the calibration nut 6. Sliding rods 8 are slidably connected to both sides of the calibration nut 6. The two ends of the sliding rods 8 are fixedly connected to the two ends of the calibration screw 7. A buffer sleeve 12 is slidably connected to the top of the mounting base 1. A buffer assembly is fixedly connected to the top of the buffer sleeve 12. An anti-deviation assembly is rotatably connected below the calibration screw 7 and above the buffer assembly.

[0030] The anti-deviation assembly includes a squeezing plate 9, a limiting plate 10, and a second spring 15. The squeezing plate 9 and the limiting plate 10 are metal plates with rubber wrapped on the outside. One end of the squeezing plate 9 is rotatably connected to the correction screw 7 or one end of the buffer assembly. The limiting plate 10 is rotatably connected to both ends of the squeezing plate 9. The two springs 15 are fixedly connected at both ends to the rotatable connection between the squeezing plate 9 and the limiting plate 10.

[0031] The drive assembly includes an adjusting gear ring 4, a drive gear 5, and a drive sleeve 16. The drive sleeve 16 has a hexagonal slot. The adjusting gear ring 4 and the drive gear 5 are rotatably connected to the translation plate 3. The adjusting gear ring 4 is fixedly connected to the outside of the correction nut 6. The adjusting gear ring 4 and the drive gear 5 mesh with each other. The drive sleeve 16 is fixedly connected above the drive gear 5.

[0032] In use, the electric wrench is used in conjunction with the hexagonal slot of the drive sleeve 16. This drives the drive gear 4 to rotate the adjusting gear ring 5 and the correction nut 6, which in turn drives the correction screw 7 to move downwards. The angle is corrected by pressing the generatrix on the mounting device through the anti-deviation component. The device does not require multiple hydraulic rods for driving. The electric wrench or electric drill bit used are essential components for maintenance and installation work, effectively reducing weight and making it easy to carry.

[0033] Two sets of anti-deviation components are installed at the top and bottom. The upper and lower sides of the busbar are squeezed by the extrusion plate 9 and the limiting plate 10. Because the outer side is wrapped with rubber, it can better fit the sides of the busbar. At the same time, the limiting plate 10 rotates inward under the pressure of the spring 15. This can better limit the bending point of the busbar to the bottom of the correction screw 7, which facilitates extrusion correction and prevents slippage during correction due to the smooth surface of the busbar.

[0034] In this embodiment, the buffer assembly includes a buffer sleeve 12, a spring 13, and a buffer rod 14. The buffer sleeve 12 is fixedly connected to the top of the adjusting base 11, the buffer rod 14 is slidably connected to the top of the buffer sleeve 12, the top of the buffer sleeve 12 is rotatably connected to the lower extrusion plate 9, and the two ends of the spring 13 are fixedly connected to the buffer rod 14 and the adjusting base 11, respectively.

[0035] Spring 13 can press the buffer rod 14 upward, thereby pressing the compression plate 9 and the limiting plate 10 on the anti-deviation component below tightly against the lower side of the busbar. This better prevents slippage and misalignment caused by the smooth surface of the busbar during correction.

[0036] In this embodiment, the bottom of the adjusting base 11 is threadedly connected to a translation screw 25, and the two ends of the translation screw 25 are rotatably connected to the inner side of the mounting base 1. The adjusting base 11 can move left and right to adjust the installation position of the busbar under the control of the translation screw 25.

[0037] In this embodiment: During use, an electric wrench is used in conjunction with the hexagonal slot of the drive sleeve 16. This drives the drive gear 4 to rotate the adjusting gear ring 5 and the correction nut 6. At this time, the correction screw 7 can be driven to move downward. The angle is corrected by pressing the generatrix on the installation device through the anti-deviation component. The device does not require multiple hydraulic rods for driving. The electric wrench or electric drill bit used are essential components for maintenance and installation work, effectively reducing weight and making it easy to carry.

[0038] Two sets of anti-deviation components are installed at the top and bottom. The upper and lower sides of the busbar are squeezed by the extrusion plate 9 and the limiting plate 10. Because the outer side is wrapped with rubber, it can better fit the sides of the busbar. At the same time, the limiting plate 10 rotates inward under the extrusion of the second spring 15. This can better limit the bending point of the busbar to the bottom of the correction screw 7, which is convenient for extrusion correction and prevents slippage during correction due to the smooth surface of the busbar.

[0039] Spring 13 can press the buffer rod 14 upward, thereby pressing the compression plate 9 and the limiting plate 10 on the anti-deviation component below tightly against the lower side of the busbar. This better prevents slippage and misalignment caused by the smooth surface of the busbar during correction. The adjusting base 11 can move left and right under the control of the translation screw 25 to adjust the installation position of the busbar.

[0040] Example 2:

[0041] Portable switch busbar connection calibration tool. This embodiment is an improvement on embodiment 1, with the following improvements: Figure 1-5 As shown, multiple movable brackets 17 are slidably connected above the adjusting base 11. An adjusting screw 19 is slidably connected to the inner side of the movable bracket 17. A swing bracket 21 is fixedly connected above the adjusting screw 19. An anti-deviation rod 18 is slidably connected to the inner side of the adjusting screw 19. The anti-deviation rod 18 can prevent the adjusting screw 19 from rotating when moving up and down. An adjusting nut 20 is threadedly connected to the outer side of the adjusting screw 19. The adjusting nut 20 is rotatably connected to the upper end of the movable bracket 17. The anti-deviation rod 18 is fixedly connected to the inner side of the movable bracket 17.

[0042] The swing bracket 21 is rotatably connected to a clamping frame 22, and a clamping plate 23 is slidably connected to the inside of the clamping frame 22. One end of the clamping plate 23 is threadedly connected to a clamping screw 24, and both ends of the clamping screw 24 are rotatably connected to the inside of the clamping frame 22.

[0043] The two ends of the busbar can be inserted between the clamping frame 22 and the clamping plate 23. Then, the clamping screw 24 is rotated to fix the two ends of the busbar. The clamping frame 22 can be rotated to fit the busbar installed at different angles. By rotating the adjusting nut 20, the adjusting screw 19 can be moved up and down, thereby adjusting the height of the clamping frame 22. It can be used for busbars with the two ends located at different horizontal heights.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
