Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a support and installation structure for a busbar shaft. Background Technology

[0002] In the power systems of high-rise buildings, industrial plants, and large public facilities, busbar trunking, as a crucial carrier for high-current transmission, typically requires vertical installation within shafts. Traditional busbar trunking support structures often employ fixed brackets or simple angle steel supports. Installation necessitates on-site cutting, drilling, and welding according to the specific dimensions of the busbar trunking. This not only results in long construction cycles and high labor intensity but also poor adjustment precision, making it difficult to adapt to the installation requirements of busbar trunking of different specifications. Furthermore, the confined space and complex environment of shafts often make it difficult to achieve symmetrical force distribution during installation using traditional structures, easily leading to uneven loading, loosening, or even slippage of the busbar trunking, posing significant safety hazards. Simultaneously, with the diversification of building structures and the increasing maintenance demands of electrical systems, existing support structures also exhibit problems such as inconvenient disassembly and assembly, and poor versatility during later maintenance, replacement, or expansion. Therefore, we propose a new vertical shaft support installation structure for busbar trunking. Utility Model Content

[0003] The main purpose of this utility model is to provide a support and installation structure for busbar shafts, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A busbar shaft support installation structure includes an installation plate. Slide grooves are provided on the front, back, left and right sides of the installation plate. An installation component is slidably connected in each of the two slide grooves. The two installation components are arranged symmetrically on the left and right. Positive and negative screws are movably connected in both of the two slide grooves. One end of the positive and negative screws passes through the slide groove and is fixedly connected to a rocker arm. The mounting component includes a clamping block, which has an L-shaped structure. A slider that is slidably connected to a sliding groove is fixedly welded to the lower end of the clamping block. The slider is threadedly connected to a positive and negative screw.

[0005] Preferably, the threads on the left and right sides of the outer surface of the positive and negative screws are in opposite directions, and the two sliders are respectively threaded to both sides of the positive and negative screws.

[0006] By adopting the above technical solution: when rotating the rocker arm, the positive and negative screws drive the two sliders to move synchronously towards or away from each other along the slide groove, so as to realize the symmetrical adjustment of the installation parts, ensure uniform clamping force, and improve adjustment efficiency and installation stability.

[0007] Preferably, the cross-section of the slider is an "I" shaped structure.

[0008] By adopting the above technical solution, the "I"-shaped structure fits tightly with the slide groove, enhancing the guiding and lateral force resistance during the sliding process, effectively preventing the slider from deviating or getting stuck during movement, and improving the overall operational stability.

[0009] Preferably, each of the two clamping blocks has a support block fixedly connected to its opposite ends. The upper surface of the support block is triangular, and the front surface of the support block is planar.

[0010] By adopting the above technical solution: the upper triangular face facilitates the positioning of the busbar trunking and provides stable support, while the flat front face facilitates its fit with the side wall of the busbar trunking, enhancing the support and positioning effect.

[0011] Preferably, a support plate is fixedly connected to one end of the clamping block, and an adjustment groove is provided at the front end of the clamping block, with a pressing component slidably connected in the adjustment groove.

[0012] By adopting the above technical solution, an installation base is provided for the clamping assembly, enabling lateral clamping adjustment of the busbar trunking and enhancing clamping firmness and adaptability.

[0013] Preferably, the clamping assembly includes an adjusting block, which is slidably connected in an adjusting groove. A pressure plate is integrally formed at the front end of the adjusting block, and a transmission block is fixedly connected to one end of the adjusting block. An adjusting screw is threaded through and connected to the transmission block, and the adjusting screw is movably connected to a support plate. A rotating block is fixedly connected to one end of the adjusting screw.

[0014] By adopting the above technical solution: the rotating block drives the adjusting screw to rotate, pushing the adjusting block to move in the adjusting groove, thereby driving the pressure plate to press the busbar groove, realizing a fast and adjustable fastening connection.

[0015] Preferably, each of the four corners of the mounting plate is fixedly welded with a fixing lug, and each of the four fixing lugs is provided with a mounting hole.

[0016] By adopting the above technical solution, it is easy to firmly fix the mounting plate to the shaft wall or bracket, ensuring the stability and reliability of the entire support structure, improving the load-bearing capacity and installation convenience.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a mounting plate with a sliding groove, positive and negative screws, and symmetrical sliding connection mounting parts, the synchronous bidirectional adjustment function of the busbar support structure is realized. The operator only needs to turn the rocker arm to drive the positive and negative screws to rotate, causing the two sliders to move synchronously in opposite directions, so that the clamping blocks on the left and right sides move towards or away from each other, quickly adapting to busbars of different widths. This design not only significantly improves installation efficiency and avoids the tedious manual measurement and adjustment process in the traditional method, but also ensures the uniform distribution of clamping force on both sides, preventing structural skewing or busbar deformation caused by uneven force. In addition, the high-precision matching structure of the "I"-shaped slider and the sliding groove further enhances the stability and torsional resistance during the sliding process, enabling smooth and stable operation even in narrow spaces such as vertical shafts, greatly improving the convenience and reliability of installation.

[0018] 2. An adjustable clamping assembly, including an adjusting screw, adjusting block, and pressure plate, is set at the front end of the clamping block. This assembly allows for lateral fine-tuning and clamping of the busbar trough placed on the support block, achieving dual fixation: the triangular upper surface of the support block provides stable bottom support, while the pressure plate applies lateral pressure to prevent displacement or loosening of the busbar trough during operation due to vibration or thermal expansion and contraction. This clamping assembly has a compact structure and high adjustment precision. Combined with the rotating block, it enables convenient manual operation and is suitable for various on-site conditions. The overall structure can be installed and disassembled without welding or complex tools, facilitating later maintenance and replacement. It has good versatility and reusability, effectively solving the problems of weak fixation and poor adaptability of traditional support structures. Attached Figure Description

Busbar trunking. Detailed Implementation

[0021] Please see Figure 1-4 This utility model provides a technical solution: A busbar shaft support installation structure includes a mounting plate 1. The mounting plate 1 has sliding grooves 2 on both the front, back, left and right sides. Each of the two sliding grooves 2 has a mounting component 3 slidably connected to it, and the two mounting components 3 are arranged symmetrically on the left and right. Both sliding grooves 2 are movably connected to positive and negative screws 4. One end of the positive and negative screws 4 passes through the sliding groove 2 and is fixedly connected to a rocker arm 5. Fixing ears 6 are fixedly welded to the four corners of the mounting plate 1, and each of the four fixing ears 6 has a mounting hole.

[0022] In this embodiment, the mounting component 3 includes a clamping block 31, which has an L-shaped structure. The lower end of the clamping block 31 is fixedly welded with a slider 32 that is slidably connected to the slide groove 2. The slider 32 is threadedly connected to the positive and negative screws 4. The threads on the left and right sides of the outer surface of the positive and negative screws 4 are reversed. The two sliders 32 are respectively threadedly connected to the two sides of the positive and negative screws 4. The cross-section of the slider 32 is an "I" shaped structure. The opposing ends of the two clamping blocks 31 are fixedly connected with support blocks 33. The upper end face of the support block 33 is triangular, and the front end face of the support block 33 is planar.

[0023] Through the above scheme: by rotating the rocker arm 5, the positive and negative screws 4 are driven to rotate. Since the threads on the left and right sides of the outer surface of the positive and negative screws 4 are reversed, and the two sliders 32 are respectively connected to the threads on their two sides, the rotation of the positive and negative screws 4 will drive the two sliders 32 to move synchronously in opposite directions in the slide groove 2, thereby driving the two mounting parts 3 to move towards or away from each other in the horizontal direction. When the two mounting parts 3 move towards each other, the clamping blocks 31 at their front ends gradually approach each other, reducing the distance between the two support blocks 33 to accommodate busbar grooves 7 of different widths. Conversely, the movement away from each other can release the busbar groove 7. The sliders 32 adopt an "I"-shaped cross-section design, which fits tightly with the slide groove 2, improving the stability and anti-torsion ability during the sliding process and preventing the mounting parts 3 from deflecting or getting stuck when subjected to force. The upper end face of the support block 33 is a triangular structure, and the front end face is a planar structure. This design can provide good guidance and stable support during the clamping process and prevent the busbar groove from slipping off.

[0024] In this embodiment, a support plate 36 is fixedly connected to one end of the clamping block 31, and an adjustment groove 34 is provided at the front end of the clamping block 31. A pressing assembly 35 is slidably connected in the adjustment groove 34. The pressing assembly 35 includes an adjustment block 351, which is slidably connected in the adjustment groove 34. A pressure plate 352 is integrally formed at the front end of the adjustment block 351. A transmission block 353 is fixedly connected to one end of the adjustment block 351. An adjustment screw 354 is threaded through and connected to the transmission block 353. The adjustment screw 354 is movably connected to the support plate 36. A rotating block 355 is fixedly connected to one end of the adjustment screw 354.

[0025] Through the above scheme: after the busbar trough 7 is initially placed on the two support blocks 33, it is further fixed by adjusting the clamping assembly 35: rotating the rotating block 355 drives the adjusting screw 354 to rotate. Since the adjusting screw 354 is threadedly connected to the transmission block 353 and movably connected to the support plate 36, the rotation of the adjusting screw 354 will push the transmission block 353 to drive the adjusting block 351 to slide back and forth in the adjusting groove 34, thereby causing the pressure plate 352 to move forward and closely adhere to the side wall of the busbar trough 7 to achieve lateral clamping and fixing.

[0026] It should be noted that this utility model is a support and installation structure for a busbar trunking shaft. During the installation of the busbar trunking 7, the following working principle achieves fast, stable, and highly adaptable installation: First, the mounting plate 1 is fixed to the shaft wall or a pre-set bracket using the fixing ears 6 at its four corners and the mounting holes, ensuring the stability and verticality of the overall structure. By rotating the rocker arm 5, the positive and negative screws 4 are rotated. Since the threads on the left and right sides of the outer surface of the positive and negative screws 4 are reversed, and the two sliders 32 are respectively connected to their respective threads, the rotation of the positive and negative screws 4 will drive the two sliders 32 to move synchronously in opposite directions within the groove 2, thereby causing the two mounting parts 3 to move towards or away from each other in the horizontal direction. When the two mounting parts 3 move towards each other, their front clamping blocks 31 gradually approach each other, reducing the distance between the two support blocks 33 to accommodate busbar trunking 7 of different widths; conversely, when they move towards each other, their front clamping blocks 31 gradually move closer, reducing the distance between the two support blocks 33 to accommodate busbar trunking 7 of different widths. The back movement releases the busbar 7, while the slider 32 adopts an "I"-shaped cross-section design, which fits tightly with the slide groove 2, improving the stability and anti-torsion ability during the sliding process and preventing the mounting part 3 from deflecting or jamming when under force. The upper end face of the support block 33 is a triangular structure, and the front end face is a planar structure. This design can provide good guidance and stable support during clamping, preventing the busbar 7 from slipping off. After the busbar 7 is initially placed on the two support blocks 33, it is further fixed by adjusting the clamping assembly 35: rotating the rotating block 355 drives the adjusting screw 354 to rotate. Since the adjusting screw 354 is threadedly connected to the transmission block 353 and movably connected to the support plate 36, the rotation of the adjusting screw 354 will push the transmission block 353 to drive the adjusting block 351 to slide back and forth in the adjusting groove 34, thereby causing the pressure plate 352 to move forward and stick to the side wall of the busbar 7 to achieve lateral clamping and fixing.
