Description

Technical Field

[0001] This utility model relates to the field of busbar support technology, specifically a busbar support. Background Technology

[0002] High-quality insulation materials are used in the busbar support, which improves the safety and reliability of the busbar support and makes the whole system more complete. The busbar support is a new type of power distribution conductor application. Compared with traditional cables, it fully demonstrates its superiority in the transmission of high current. At the same time, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points of the two ends of the busbar trunking and the insertion points of the branch ports are greatly reduced.

[0003] Busbar trunking (or simply busbar trunking) is a busbar system composed of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulation materials, and related accessories. It can be manufactured as a plug-in type enclosed busbar with junction boxes at intervals, or as a feeder type enclosed busbar without junction boxes in the middle. In the power supply systems of high-rise buildings, power and lighting circuits are often installed separately, and busbar trunking, as the main power supply line, is installed vertically along the wall in the electrical shaft, one or more times.

[0004] Chinese Utility Model Patent Publication No. CN 212543314 U discloses a busbar bracket that can fix and limit busbar troughs of different sizes. This utility model solves the problem that existing busbar brackets have low versatility and cannot fix busbar troughs of different sizes. This utility model has strong versatility, is easy to fix busbar troughs of different sizes, and avoids the busbar trough from shifting after being subjected to external impact. It has a simple structure and strong practicality. However, when installing the busbar trough, it is necessary to fix the busbar trough from three different directions, which is relatively cumbersome and has poor practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a busbar support that can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a busbar support, including a mounting frame, a channel steel, and a load-bearing frame located below the channel steel. A slide rail is fixedly installed on the inner surface of the load-bearing frame. Limiting holes are opened at equal intervals at one end of the load-bearing frame near the mounting frame. A guide groove is opened at the center of one end of the load-bearing frame near the mounting frame. A clamping component is slidably installed on the inner side of the guide groove.

[0007] The clamping assembly includes a clamping block, a fixing plate is fixedly installed at the end of the clamping block away from the mounting frame, and a pulley that is slidably connected to the slide rail is provided at the end of the fixing plate near the clamping block.

[0008] Preferably, the mounting bracket is provided with a reinforcing bolt at one end near the load-bearing frame, a screw stiffener is slidably installed on the inner surface of the first channel steel, a long screw threaded to the load-bearing frame is provided on the inner side of the first channel steel, a fixing seat is fixedly installed on one end of both sides of the load-bearing frame near the first channel steel, a connecting seat is fixedly installed on one end of the fixing seat near the mounting bracket, a second channel steel is provided on one side of the connecting seat near the mounting bracket, and an anti-seismic connecting component is fixedly installed on one end of the second channel steel near the connecting seat.

[0009] The above technical solutions improve the rigidity of the connection between the mounting frame and the wall by setting reinforcing bolts, adjust the overall rigidity of the support by setting screw stiffeners that slide within the channel steel, and enable the installation of two sets of load-bearing frames by using long screws. The seismic resistance of the device can be improved by setting seismic connection components.

[0010] Preferably, the seismic connecting member and the connecting seat are rotatably connected, and the seismic connecting member and the channel steel are slidably connected.

[0011] Through the above technical solution, by setting the seismic connection component and the connecting seat to be rotatably connected, the staff can freely adjust the angle of the seismic connection component and the connecting seat during installation. In addition, the design of the seismic connection component and the channel steel being slidably connected can realize the dual-degree-of-freedom adjustment of the device, thereby improving the seismic resistance of the support.

[0012] Preferably, the clamping assembly further includes a limiting block, a limiting pin, and a locking screw. The limiting block is provided on the side of the clamping block away from the load-bearing frame. A limiting pin that is inserted into the limiting hole is fixedly installed on the end of the limiting block near the clamping block. A locking screw is threadedly connected to the center position of the side of the limiting block away from the clamping block.

[0013] The above technical solution incorporates a clamping component, which facilitates the clamping of busbar trunking of varying sizes and improves the stability of the busbar trunking clamping.

[0014] Preferably, the limiting pins are provided in two identical sets, and the two sets of limiting pins are symmetrically distributed at the bottom of the limiting block. Both sets of limiting pins and limiting holes are installed by insertion.

[0015] With the above technical solution, after the staff installs the busbar trunking on the top of the load-bearing frame, the clamping block can be manually adjusted to fit the busbar trunking through the sliding connection between the clamping block and the guide groove. Then, through the design of plug-in installation with limit pin and limit hole, the staff only needs to align the limit pin with the limit hole and insert it to achieve quick locking of the clamping block.

[0016] Preferably, the load-bearing frame is provided in two identical sets, and both sets of load-bearing frames are threadedly connected to the long screw.

[0017] Through the above technical solution, the synergistic effect of the double load-bearing frame and the long screw rod ensures structural rigidity while achieving rapid installation and adjustment and high reliability.

[0018] Preferably, the pulleys are provided in four identical sets, which are symmetrically distributed on the top of the fixed plate, and all four sets of pulleys are slidably connected to the slide rail.

[0019] The above technical solution, by setting the pulley and the slide rail to be in a sliding connection, can effectively reduce the friction between the clamping block and the slide rail, and by setting four sets of identical pulleys, can improve the stability of the clamping block when it moves.

[0020] Compared with the prior art, the present invention provides a busbar support, which has the following advantages:

[0021] 1. This busbar support bracket installs the busbar trunking on top of the load-bearing frame. The clamping blocks are then slidably connected to the guide rails. Operators can manually adjust the clamping blocks until they are flush with the outer shell of the busbar trunking. The sliding connection between the pulleys and the guide rails on the inner side of the clamping blocks effectively reduces friction between the clamping blocks and the load-bearing frame, thus improving the service life of the load-bearing frame. After adjustment, the limit pins and limit holes are designed for plug-in installation. The limit pins are aligned with the limit holes and inserted, and then the clamping blocks are fixed to the load-bearing frame using locking screws, thereby improving the stability of the busbar trunking.

[0022] 2. This busbar support, by setting two sets of load-bearing frames, can simultaneously install two sets of busbar trunking, which can effectively reduce the space occupied. During maintenance, both sets of busbar trunking can be operated in the same position, reducing troubleshooting time. Through the threaded connection between the double load-bearing frames and the long screw, the spacing between the two sets of busbar trunking can be adjusted, which can facilitate the installation of two sets of busbar trunking of different specifications. The rotation and sliding of the seismic connection components can achieve double buffering of the support, thereby improving the seismic resistance of the support. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-6 As shown, the present invention provides a busbar support, including a mounting frame 1, a channel steel 3, and a load-bearing frame 6 located below the channel steel 3. A slide rail 11 is fixedly installed on the inner surface of the load-bearing frame 6. Limiting holes 12 are opened at equal intervals at one end of the load-bearing frame 6 near the mounting frame 1. A guide groove 13 is opened at the center of one end of the load-bearing frame 6 near the mounting frame 1. A clamping component 14 is slidably installed on the inner side of the guide groove 13.

[0032] The clamping assembly 14 includes a clamping block 1401. A fixing plate 1402 is fixedly installed at the end of the clamping block 1401 away from the mounting frame 1. A pulley 1403 that is slidably connected to the slide rail 11 is provided at the end of the fixing plate 1402 near the clamping block 1401.

[0033] Specifically, a reinforcing bolt 2 is provided at one end of the mounting frame 1 near the load-bearing frame 6. A threaded stiffener 4 is slidably installed on the inner surface of the channel steel 3. A long threaded rod 5, threaded to the load-bearing frame 6, is provided on the inner side of the channel steel 3. Fixing seats 7 are fixedly installed on both sides of the load-bearing frame 6 near one end of the channel steel 3. A connecting seat 8 is fixedly installed at one end of the fixing seat 7 near the mounting frame 1. A channel steel 9 is provided on one side of the connecting seat 8 near the mounting frame 1. An anti-seismic connection component 10 is fixedly installed at one end of the channel steel 9 near the connecting seat 8. The advantages are that the reinforcing bolt 2 improves the rigidity of the connection between the mounting frame 1 and the wall, the threaded stiffener 4 slides within the channel steel 3 to adjust the overall rigidity of the support, the long threaded rod 5 allows for the installation of two sets of load-bearing frames 6, and the anti-seismic connection component 10 improves the seismic resistance of the device.

[0034] Specifically, the seismic connecting member 10 is rotatably connected to the connecting seat 8, while the seismic connecting member 10 is slidably connected to the channel steel 9. The advantage is that by designing the seismic connecting member 10 and the connecting seat 8 as a rotatable connection, workers can freely adjust the angle between them during installation. Combined with the slidable connection between the seismic connecting member 10 and the channel steel 9, this allows for dual-degree-of-freedom adjustment of the device, improving the seismic resistance of the support.

[0035] Specifically, the clamping assembly 14 also includes a limiting block 1404, a limiting pin 1405, and a locking screw 1406. The limiting block 1404 is located on the side of the clamping block 1401 away from the load-bearing frame 6. A limiting pin 1405, which is inserted into the limiting hole 12, is fixedly installed on the end of the limiting block 1404 near the clamping block 1401. A locking screw 1406 is threadedly connected to the center position of the limiting block 1404 on the side away from the clamping block 1401. The advantage is that the clamping assembly 14 facilitates the clamping of busbar trunking of different sizes, improving the stability of the busbar trunking clamping.

[0036] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, two identical sets of limit pins 1405 are provided, symmetrically distributed at the bottom of the limit block 1404. Both sets of limit pins 1405 are plug-in installed with the limit hole 12. The advantage is that after the worker installs the busbar trunking on top of the load-bearing frame 6, the clamping block 1401 can be manually adjusted to fit the busbar trunking through the sliding connection between the clamping block 1401 and the guide groove 13. Then, due to the plug-in design of the limit pins 1405 and the limit hole 12, the worker only needs to align the limit pin 1405 with the limit hole 12 and insert it to quickly lock the clamping block 1401.

[0038] Specifically, the load-bearing frame 6 has two identical sets, both sets of load-bearing frames 6 are threadedly connected to the long screw 5. The advantage is that, through the synergistic effect of the double load-bearing frames 6 and the long screw 5, while ensuring structural rigidity, it achieves rapid installation and adjustment as well as high reliability.

[0039] Specifically, four identical sets of pulleys 1403 are provided, symmetrically distributed on the top of the fixed plate 1402, and all four sets of pulleys 1403 are slidably connected to the slide rail 11. The advantage is that by designing the pulleys 1403 to slide rail 11 in a slidable connection, the friction between the clamping block 1401 and the slide rail 11 can be effectively reduced, and by using four identical sets of pulleys 1403, the stability of the clamping block 1401 during movement can be improved.

[0040] Working principle: In use, the mounting bracket 1 is first fixed to the wall with the reinforcing bolts 2. Then, the long screw 5 is threadedly connected to the load-bearing frame 6. When the workers install the load-bearing frame 6, the distance between the two sets of load-bearing frames 6 can be adjusted to facilitate support for busbar trunking of different sizes. After the busbar trunking is installed on top of the load-bearing frame 6, the clamping block 1401 is slidably connected to the guide groove 13. Combined with the sliding connection between the pulley 1403 and the slide rail 11, the friction between the clamping block 1401 and the slide rail 11 can be effectively reduced. Then, the clamping block can be manually adjusted. 1401 is fitted to the busbar trunking, and then the limit pin 1405 and the limit hole 12 are designed for plug-in installation. The limit pin 1405 is inserted into the limit hole 12 and then locked with the locking screw 1406 to further fix the clamp 1401, thereby improving the stability of the busbar trunking. Finally, the second channel steel 9 is rotatably connected to the connecting seat 8 through the seismic connection member 10, and the seismic connection member 10 and the second channel steel 9 are slidably connected. The rotation and sliding of the seismic connection member 10 can realize the double buffer of the bracket, thereby improving the seismic resistance of the bracket.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
