Description

Technical Field

[0001] This utility model relates to an auxiliary device for connecting and fixing busbar trunking. Background Technology

[0002] With the increasing demands for power transmission density from data centers, high-rise buildings, and large factories, high-density busbar trunking has gradually replaced traditional cable trays due to its advantages such as large current carrying capacity, quick installation, and convenient maintenance.

[0003] When installing busbar trunking on site, the interfaces of two busbar trunking sections are usually connected and locked using connectors. However, the existing construction method generally uses pry bars to adjust and connect the two sets of busbar trunking sections to the connectors. However, pushing the pry bar requires strong manual force, which can easily damage the copper busbar teeth. Moreover, the pry bar is inconvenient to use, resulting in low connection efficiency between the two sets of busbar trunking sections.

[0004] Therefore, an auxiliary device for fixing busbar trunking connection is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for connecting and fixing busbar trunking, so as to solve the problem mentioned in the background art that the existing construction methods generally use pry bars for adjustment to connect the two sets of busbar trunking and connectors tightly, but the pushing of the pry bar relies on manual force, which can easily damage the copper busbar teeth and result in low connection efficiency between the busbar trunking.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a busbar trunking connection and fixing auxiliary device, comprising: A fixing clamp is used to fix the upper end of the first busbar trunking; A movable clamp is used to fix the upper end of the second busbar trunking and is arranged opposite to the fixed clamp; Both the fixed clamp and the movable clamp are L-shaped, and their vertical sections are used to abut against the side wall of the corresponding busbar trough. The horizontal section of the fixed clamp is provided with an internal cavity, and a spacing adjustment component is installed in the internal cavity. The upper wall of the fixed clamp is provided with a control handwheel. The horizontal section of the movable clamping plate is provided with an inner lining sleeve; The spacing adjustment assembly includes a shaft and a transmission mechanism. One end of the shaft is threadedly connected to the inner lining sleeve, and the other end extends into the inner cavity and is rotatably connected to the fixed clamping plate. The transmission mechanism, located on the outer periphery of the shaft and driven by the control handwheel, is used to drive the shaft to rotate and move axially, thereby causing the movable clamping plate to move closer to or away from the fixed clamping plate to clamp or release the two sets of busbar slots.

[0007] Preferably, the transmission mechanism includes a gearbox disposed in a built-in cavity, a transmission gear is disposed inside the gearbox on the outer periphery of the shaft, a drive gear is meshed on the outer periphery of the transmission gear, and the upper part of the drive gear is coaxially fixed to the control handwheel via a rotating shaft.

[0008] Preferably, the two side walls of the fixed clamping plate are provided with limiting grooves for linear movement of the movable clamping plate.

[0009] Preferably, the movable clamping plate is provided with two sets of guide rods at the connecting end of the fixed clamping plate. The free end of the guide rod is fixed to a limiting plate, and the limiting plate is slidably embedded in the limiting groove to guide the movable clamping plate to move linearly.

[0010] Preferably, the gearbox has two sets of channels for the movement of the guide rod, so that the guide rod can move through the channels on the gearbox side.

[0011] Preferably, a moving groove is provided on the inner side of the vertical section of both the fixed clamping plate and the movable clamping plate, and two sliding plates that can move relative to or towards each other are slidably installed in the moving groove, and a clamping plate is provided at each of the sliding plates.

[0012] Preferably, the clamping plate is provided with an anti-slip pad on the side facing the busbar groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves precise axial displacement control through a spacing adjustment component. By rotating the control handwheel, the interfaces of the two sets of busbar trunking can be quickly connected to the connector, which can prevent damage to the copper busbars due to excessive force and improve the service life and reliability of the equipment.

[0014] By controlling the handwheel to adjust the spacing component, manual intervention can be reduced, improving the ease of operation. Compared with the traditional pry bar adjustment method, it completely eliminates problems such as damage to the copper busbar teeth caused by excessive thrust, while avoiding the inconvenience and labor intensity caused by using a pry bar in the traditional method.

[0015] Furthermore, it enables quick and precise adjustment of the insertion position between the busbar trunking and the connector, thereby avoiding the inefficient method of relying on manual pushing in traditional construction and improving installation efficiency.

[0016] The quick adjustment of the position between the movable clamp and the fixed clamp can better clamp the busbar trunking, ensuring a tight connection between the busbar trunking and the connector, and ensuring the stability and safety of power transmission. Attached Figure Description

[0019] To address the common problem in existing construction methods that rely on pry bars for adjustment and tight connection between busbar trunking and connectors, which necessitates manual prying and easily damages the copper busbar teeth, resulting in low connection efficiency between busbar trunking, this invention provides a busbar trunking connection and fixing auxiliary device. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] Please see Figure 1-7 This utility model provides a busbar trunking connection and fixing auxiliary device, including: Fixed clamp 1 is used to fix the upper end of the first busbar trunking; The movable clamp 2 is used to fix the upper end of the second busbar trunking and is arranged opposite to the fixed clamp 1; Both the fixed clamp 1 and the movable clamp 2 are L-shaped, and their vertical sections are used to abut against the side wall of the corresponding busbar trough. The fixed clamping plate 1 has limiting grooves 12 on both sides for linear movement of the movable clamping plate 2.

[0021] The movable clamping plate 2 is provided with two sets of guide rods 22 at the connecting end of the fixed clamping plate 1. The free end of the guide rod 22 is fixedly connected to a limiting plate 23, which is slidably embedded in the limiting groove 12 to guide the movable clamping plate 2 to move linearly. The gearbox 321 has two sets of channels 325 for the movement of the guide rods 22, so that the guide rods 22 can move on the gearbox 321 side through the channels 325.

[0022] Both the fixed clamping plate 1 and the movable clamping plate 2 have movable grooves 5 on their inner vertical sections. Two sliding plates 6 that can move relative to or towards each other are slidably installed in the movable grooves 5. Each sliding plate 6 is provided with a clamping plate 7. The clamping plate 7 is provided with an anti-slip pad 8 on the side facing the busbar groove.

[0023] The horizontal section of the fixed clamp 1 is provided with an internal cavity 11, and the internal cavity 11 is equipped with a spacing adjustment component 3. The upper wall of the fixed clamp 1 is provided with a control handwheel 4. The horizontal section of the movable clamping plate 2 is provided with an inner lining sleeve 21; The spacing adjustment assembly 3 includes a shaft 31 and a transmission mechanism 32. One end of the shaft 31 is threadedly connected to the inner sleeve 21, and the other end extends into the inner cavity 11 and is rotatably connected to the fixed clamping plate 1. The transmission mechanism 32 is disposed on the outer periphery of the shaft 31 and is driven by the control handwheel 4. It is used to drive the shaft 31 to rotate and move axially, thereby driving the movable clamping plate 2 to move closer to or away from the fixed clamping plate 1 to clamp or release the two sets of busbar grooves.

[0024] The transmission mechanism 32 includes a gearbox 321 disposed in the built-in cavity 11. Inside the gearbox 321, a transmission gear 322 is disposed on the outer periphery of the shaft 31. A drive gear 323 is meshed and connected on the outer periphery of the transmission gear 322. The upper part of the drive gear 323 is coaxially fixed to the control handwheel 4 through a rotating shaft 324.

[0025] The working principle of the busbar trunking connection and fixing auxiliary device provided by this utility model is as follows: When two sets of busbar trunking need to be connected to the connector, the two sets of busbar trunking are initially connected to the connector, and then the fixed clamping plate 1 and the movable clamping plate 2 are respectively placed above the two sets of busbar trunking, so that the vertical sections of the fixed clamping plate 1 and the movable clamping plate 2 abut against the side wall of the busbar trunking. Pull the two sets of clamping plates 7 in opposite directions, so that they move in opposite directions at the moving groove 5 via the sliding plate 6, and abut against the side wall above the busbar groove via the anti-slip rubber pad 8. Rotating the control handwheel 4 causes the drive gear 323 to rotate via the rotating shaft 324. The drive gear 323 meshes with the transmission gear 322, which in turn drives the shaft 31 to rotate. The shaft 31 moves linearly through the threaded inner sleeve 21, causing the movable clamping plate 2 to move toward the fixed clamping plate 1. This tightly inserts the movable clamping plate 2 and the fixed clamping plate 1 into the two ends of the connector, allowing for connection via the connector.

[0026] 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.
