Description

Technical Field

[0001] This utility model relates to the field of busbar trunking fixing technology, and in particular to a busbar trunking fixing device based on factory power transmission. Background Technology

[0002] Busbar trunking is a new type of conductor formed by using copper or aluminum as the conductor, supporting it with non-alkaline insulation, and then installing it in a metal trough. Busbar trunking features large current capacity, small voltage drop, strong short-circuit load capacity, non-combustible operation, high safety and reliability, long service life, easy addition or alteration of equipment in power distribution systems, simple construction, inspection and maintenance, and a modern aesthetic. Busbar trunking is gradually replacing electrical wires and cables for power transmission in factories. During use, busbar trunking typically requires fixing devices for secure installation.

[0003] For example, a Chinese patent (patent publication number: CN220652933U) discloses a fixing device for a cable well busbar trunking, which uses an automatic fixing mechanism to achieve the self-fixing function of the busbar trunking.

[0004] When the aforementioned existing technology is actually used in a factory, the ends of the busbar trunking are connected to distribution boxes. The distribution boxes and other machines will generate vibrations during operation. These vibrations will be transmitted to the busbar trunking, causing the connecting parts to loosen and resulting in safety accidents. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art mentioned above and to provide a busbar fixing device based on factory power transmission.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a busbar fixing device based on factory power transmission, including...

[0008] Wall-mounted fasteners installed on the outside of the busbar trunking.

[0009] Busbar trough fixing clips, wherein two busbar trough fixing clips are provided, and the two busbar trough fixing clips are slidably connected to fix the bottom and top of the busbar trough, namely a bottom busbar trough fixing clip located at the bottom and a top busbar trough fixing clip located at the top;

[0010] A telescopic mechanism is used to adjust the distance between the bottom busbar groove fixing clamp and the top busbar groove fixing clamp;

[0011] A shock-absorbing connection assembly, comprising a bolt passing through a bottom busbar fixing clamp and a wall connection fixing member; and a spring passing through the bolt.

[0012] Furthermore, the wall connection fastener includes two channel steels arranged opposite to each other, and each of the two channel steels is provided with a wall fixing plate for fixing to the wall.

[0013] Furthermore, the busbar trough fixing clamp consists of two symmetrically arranged first busbar trough fixing clamps and second busbar trough fixing clamps. Each of the first busbar trough fixing clamps and the second busbar trough fixing clamp consists of an angle steel and two clamping plates. The first busbar trough fixing clamp has a vertical through-hole for a fitting groove, and the second busbar trough fixing clamp has a fitting plate. The fitting plate and the fitting groove are matched and arranged.

[0014] Furthermore, a limiting slide rod is vertically fixed on the bottom busbar groove fixing clamp, and a through-hole is provided on the top busbar groove fixing clamp. The limiting slide rod and the through-hole are in sliding fit.

[0015] Furthermore, the telescopic mechanism adopts an electric push rod, the main body of which is mounted on the bottom busbar groove fixing clamp, and the push rod thread of which is threaded through the bottom of the top busbar groove fixing clamp.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting two symmetrical channel steels and wall fixing plates on the channel steels, the busbar trunking can be limited to the left and right. When combined with the interlocking connection of the two clamping plates set at the front and back, the busbar trunking itself can be fixed. This simplifies the structure of the connecting parts, reduces production costs and the impact of vibration. In addition, after being fixedly connected to the wall, resonance of the busbar trunking can be further avoided, loosening of the connecting parts can be prevented, and the stability of use can be greatly increased.

[0018] 2. By setting spring bolts between the channel steel and the angle steel, the rigid connection is transformed into a flexible connection, which further stabilizes the connection and greatly reduces the impact of vibration. Attached Figure Description

[0024] Example

[0025] like Figure 1 and Figure 2 As shown

[0026] A busbar fixing device based on factory power transmission, including

[0027] The wall connection fastener 1 is set on the outside of the busbar trough 5. Specifically, the wall connection fastener 1 includes two channel steels 11 arranged opposite to each other. The two channel steels 11 are close to each other on both sides of the busbar trough 5, and each of the two channel steels 11 is provided with a wall fixing plate 12 at its rear end. The wall fixing plate 12 is provided with holes for fixing it to the wall.

[0028] This solution can further prevent busbar resonance, prevent loosening of connecting parts, and greatly increase operational stability.

[0029] Two busbar trunking clamps 2 are provided, and the two busbar trunking clamps 2 are slidably connected to fix the bottom and top of the busbar trunking 5. These are a bottom busbar trunking clamp 21 located at the bottom and a top busbar trunking clamp 22 located at the top. Specifically, the bottom busbar trunking clamp 21 and the top busbar trunking clamp 22 have the same structure, both consisting of two symmetrically arranged first busbar trunking clamps 211 and second busbar trunking clamps 212. Both the first busbar trough fixing clamp 211 and the second busbar trough fixing clamp 212 are composed of an angle steel 2111 and two clamping plates 2112 arranged in front and behind. The angle steel 2111 has two fixing holes 23 on its side plate for fixing it to the busbar trough 5. The difference is that the clamping plate 2113 of the first busbar trough fixing clamp 211 has a vertically penetrating groove 2113, and the clamping plate 2112 of the second busbar trough fixing clamp 212 has a clamping plate 2114, which can slide into the clamping groove 2112.

[0030] With this scheme, after fitting, the channel steels set on the left and right abutting each other limit the left and right movement of the busbar trough 5, and the fitting connection limits the front and rear movement of the busbar trough 5. When the two are used together, the fixing effect of the busbar trough 5 is ensured. Moreover, it replaces the connecting parts in the existing technology, simplifies the structure of the connecting parts, and reduces the production cost and the impact of vibration.

[0031] Specifically, the telescopic mechanism 3 is provided on the left and right sides of the bottom busbar trough fixing clamp 21 and the top busbar trough fixing clamp 22, respectively. Furthermore, the telescopic mechanism 3 adopts an electric push rod 31. The main body of the electric push rod 31 and the limiting slide rod 32 are both vertically fixed on the bottom busbar trough fixing clamp 21. The top of the push rod of the electric push rod 31 is threaded, and it is connected to the bottom plate of the top busbar trough fixing clamp 22 through the threaded countersunk hole. The upper end of the limiting slide rod 32 is inserted into the top busbar trough fixing clamp 22 through the insertion limiting hole 221.

[0032] This solution allows for adjustment of the spacing between the two busbar fixing clamps, making it easier to fix the busbar 5 at a higher position and avoiding the hassle of manual ladder installation.

[0033] Preferably, four limiting slide rods 32 are used, and they are installed in pairs on both sides of the busbar trough 5. This design prevents them from rotating when sliding up and down.

[0034] Preferably, the telescopic mechanism 3 can also be in two sets, one set including two threaded rods and an internal threaded sleeve. The two threaded rods are vertically fixed to the side wall between the bottom busbar groove fixing clamp 21 and the top busbar groove fixing clamp 22, and then the internal threaded sleeve is sleeved between the two threaded rods. With this scheme, the distance between the two threaded rods can be changed by rotating the internal threaded sleeve, thereby changing the distance between the bottom busbar groove fixing clamp 21 and the top busbar groove fixing clamp 22. The structure is simpler, the cost of use is low, and disassembly is convenient.

[0035] The shock-absorbing connection assembly 4, specifically, the bottom plates of the two angle steels 2111 in the bottom busbar trough fixing clamp 21 are respectively connected to the channel steel 11 on the same side by bolts 42, and springs 41 are installed on the bolts 42 located between the angle steels 2111 and the channel steel 11 to abut against each other.

[0036] With this solution, bolt 42 connects the busbar 5 to the wall connection fastener 1, and spring transforms the rigid connection into a flexible connection, further stabilizing the interconnection and greatly reducing the impact of vibration, thereby further ensuring the achievement of the above functions.

[0037] Preferably, in order to improve the fixing effect, two bolts 42 and two springs 41 are respectively used for mating, and the upper top wall of the channel steel 11 is provided with several connecting holes 111 for mounting bolts 42; this facilitates the adaptation to busbar trunking fixing clamps 2 of various lengths and expands the scope of application.

[0038] How this device works:

[0039] Before use, place the busbar 5 close to the wall, tighten the bolts 42, then align the two channel steels 11 horizontally and install them symmetrically on both sides of the busbar 5, and place them close to the busbar 5 so that the fitting plate 2114 on the second busbar fixing clamp 212 is fitted into the fitting groove 2113 on the first busbar fixing clamp 211. Then fix both of them to the busbar 5 through the fixing hole 23. Then fix both wall fixing plates 12 to the wall with screws. Then start the electric push rods 31 on both sides to push the two top busbar fixing clamps 22 upwards so that the two top busbar fixing clamps 22 are installed and fitted. This achieves the self-fixation of the busbar 5 and its fixation to the wall.

[0040] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
