Description

Technical Field

[0001] This invention relates to the field of busbar technology, specifically to a busbar self-positioning installation structure. Background Technology

[0002] Busbar trunking, as a highly efficient power transmission device, is widely used in power transmission systems. Traditional busbar trunking structures typically include the busbar trunking body, side guard plates, conductive bars, side clamps, and insulating plates. During installation, these components are sequentially locked and secured using double-headed locking bolts. In actual installation, to ensure the conductive bars can smoothly insert into the gaps between adjacent insulating plates, the gaps between the insulating plates often need to be pre-enlarged.

[0003] However, the adjustment of the gap between the insulation boards lacks a dedicated guiding and driving mechanism. It usually relies on manual manipulation or forced insertion, and then is forcibly tightened by double-headed locking bolts. During installation, the position of the insulation boards needs to be adjusted manually and repeatedly, resulting in low construction efficiency and poor fault tolerance.

[0004] Therefore, we propose a self-positioning installation structure for busbar trunking to solve the above problems. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example

[0040] like Figure 1-12 As shown in the figure, an embodiment of the present invention proposes a self-positioning installation structure for a busbar trunking, including a busbar trunking body 1, a side guard plate 2, conductive busbars 3, a side clamping plate 4, an insulating plate 5, and a double-headed locking bolt 6. The side guard plate 2 is connected to the side of the busbar trunking body 1, the conductive busbars 3 are disposed on the inner side of the side guard plate 2, the insulating plates 5 are correspondingly inserted between adjacent conductive busbars 3, and the side clamping plates 4 are installed on the outer side of the conductive busbars 3. The double-headed locking bolt 6 transversely penetrates the side clamping plate 4, the insulating plate 5, and the conductive busbars 3, and is used to achieve overall locking after final positioning. The above connection relationships are all mature prior art in this field, and therefore will not be described in detail.

[0041] A guide block 9 is movably connected to the top of the insulating plate 5, and a contact plate 10 is connected to the top of the guide block 9; multiple side push plates 12 are inserted at intervals into the gaps between two adjacent sets of contact plates 10, and the rear ends of the multiple side push plates 12 are fixedly connected by a connecting rod 11 to achieve synchronous movement; the rear end of the connecting rod 11 is provided with a set of guide mechanisms for pushing the connecting rod 11 to move back and forth.

[0042] like Figure 1 , Figure 2 and Figure 7 As shown, a movable top cover 7 covers the side clamping plate 4 and the insulating plate 5; the surface of the movable top cover 7 is provided with a long strip-shaped limiting groove 8; the upper part of the guide block 9 passes through this limiting groove 8 and can slide radially along the groove of the limiting groove 8, thereby providing horizontal movement guidance for the guide block 9 and the insulating plate 5 connected to it.

[0043] like Figure 9 , Figure 10 As shown, to achieve adaptive adjustment and reduce wear, the insulating plate 5 and the guide block 9 are rotatably connected. Specifically, a limiting groove 26 is provided on the top of the insulating plate 5, and a shaft insert 27 is fixedly provided on the bottom of the guide block 9. The shaft insert 27 is rotatably embedded in the limiting groove 26, allowing the guide block 9 to rotate relative to the insulating plate 5 within a certain angle. Similarly, an axial groove is provided on the top of the guide block 9, and an insert block is fixedly provided on the bottom of the contact plate 10. The insert block is rotatably embedded in the axial groove, allowing the contact plate 10 to rotate freely relative to the guide block 9. When the inclined surface of the side push plate 12 contacts the contact plate 10, the contact plate 10 can effectively reduce sliding friction through rotation.

[0044] like Figure 4 , Figure 5 As shown, the side push plate 12 preferably adopts a triangular structure, and its inclined surface is in contact with the outer wall of the contact plate 10 during the insertion process; when the side push plate 12 is pushed forward, its inclined surface applies an outward pushing force to the contact plate 10.

[0045] like Figure 6 , Figure 8 As shown, the guiding mechanism is crucial for the insertion of the drive side push plate 12. It includes components such as a push plate 13, a push post 17, a limiting plate 18, and a low-sliding slider 19. Specifically, a connecting plate 14 is fixedly mounted on the side of the connecting rod 11, and the push plate 13 is fixedly mounted on the top of the connecting plate 14. A push groove 16 is formed at the bottom of the push plate 13; the side portion of the push post 17 is installed within the push groove 16, and a low-sliding slider 19 is fixedly mounted at the bottom of the push post 17. The limiting plate 18 is sleeved on the outside of the low-sliding slider 19, providing sliding guidance for the low-sliding slider 19.

[0046] To achieve symmetrical expansion, two sets of push plates 13 are symmetrically distributed, and the grooves of the two sets of push grooves 16 are combined to form a V-shape; a handle for easy gripping can be provided on the top of the push column 17. The low slider 19 can slide smoothly along the gap between the two sets of limiting plates 18; in addition, a guide pressure plate 20 is integrally formed on the side of the limiting plate 18, which presses against the top of the connecting rod 11 to limit the vertical jump of the connecting rod 11.

[0047] like Figure 8 As shown, in order to ensure the stability of the two sets of push plates 13 when moving in the horizontal direction, one set of push plates 13 has an insertion hole 24 on its side, and the other set of push plates 13 has a guide rod part 25 fixed on its side. The guide rod part 25 is slidably inserted into the groove of the insertion hole 24 to provide guidance for the relative movement of the two sets of push plates 13.

[0048] like Figure 7 As shown, an assembly base plate 21 is fixedly provided at the bottom of the movable top cover plate 7. An upwardly extending L-shaped limiting strip 23 is fixedly provided at the top of the side clamping plate 4. The L-shaped limiting strip 23 presses against the top of the assembly base plate 21 to prevent the assembly base plate 21 from coming off upward. At the same time, an upwardly protruding top protrusion 22 is fixedly provided at the end of the assembly base plate 21. When the movable top cover plate 7 slides to one side, the top protrusion 22 will form a limiting interference with the end of the L-shaped limiting strip 23 to prevent the entire assembly base plate 21 from completely detaching from the restriction of the L-shaped limiting strip 23.

[0049] like Figure 11 , Figure 12 As shown, to temporarily lock the gap after adjustment for easier subsequent installation, a strip-shaped pressure plate 28 is installed behind the push plate 13. A rotating seat 29 is fixed to the surface of the strip-shaped pressure plate 28, and a rotating shaft plate 30 is rotatably connected to the groove of the rotating seat 29 via a rotating shaft. An adjusting pressure plate 31 and a long handle 32 are fixed to the surface of the rotating shaft plate 30. Multiple spaced positioning slots 34 are provided on the back of the push plate 13. Correspondingly, positioning inserts 33 are fixed to both ends of the adjusting pressure plate 31. By rotating the long handle 32, the adjusting pressure plate 31 can be rotated, thereby causing the positioning inserts 33 to insert into or disengage from the slots of the positioning slots 34.

[0050] In use: First, install the movable top cover plate 7 and its bottom mounting base plate 21 on the top of the side clamping plate 4; at this time, the L-shaped limiting strip 23 presses on the top mounting base plate 21, and the top protrusion 22 is located inside the L-shaped limiting strip 23 to prevent it from falling out.

[0051] Then, holding the handle at the top of the push column 17, push the push column 17 forward. The side portion of the push column 17 slides within the V-shaped push groove 16 at the bottom of the two sets of push plates 13. Due to the inclined surface of the push groove 16, the forward movement of the push column 17 is converted into a lateral thrust on the two sets of push plates 13, forcing the two sets of push plates 13 to separate outward, i.e., in opposite directions.

[0052] When the two sets of push plates 13 separate to the sides, the two connecting rods 11 are also moved to the sides via the connecting plate 14. Since multiple side push plates 12 are fixed to the front end of the connecting rods 11, the lateral movement of the connecting rods 11 will cause all the side push plates 12 to be inserted into the gaps between the two adjacent sets of contact plates 10 simultaneously.

[0053] During insertion, the side-push plate 12 with its triangular bevel continuously contacts and presses against the outer wall of the contact plate 10. This lateral thrust is transmitted to the guide block 9 through the contact plate 10, which in turn pushes the insulating plate 5 outward, thereby precisely and uniformly increasing the gap between adjacent sets of insulating plates 5, providing space for the smooth insertion of the conductive busbar 3. During this process, the guide block 9 slides radially along the limiting groove 8, ensuring the accuracy of the movement direction. At the same time, the contact plate 10 rotates when it contacts the bevel of the side-push plate 12, greatly reducing sliding wear.

[0054] Once the side push plate 12 is fully inserted and the spacing of the insulating plates 5 is adjusted to the required width, the long handle 32 can be rotated to cause the rotating shaft plate 30 to drive the adjusting pressure plate 31 to rotate, inserting the positioning inserts 33 at both ends of the adjusting pressure plate 31 into the corresponding positioning horizontal slots 34 on the back of the push plate 13. At this time, the spacing between the two sets of push plates 13 is temporarily locked, and the operator can release their hand, with the gap remaining unchanged.

[0055] With the gap widened, accurately insert the conductive busbar 3 into place. After confirming that the conductive busbar 3 and the insulating plate 5 are fully inserted, first pull the push post 17 in the opposite direction to disengage it from the push groove 16. Then, rotate the long handle 32 in the opposite direction to pull the positioning insert 33 out of the positioning horizontal slot 34 and release the lock; at this time, the side push plate 12 naturally exits the gap of the contact plate 10 under the action of structural spring force or external force, and the gap of the insulating plate 5 returns to the normal fit. Finally, use the existing double-headed locking bolt 6 to transversely penetrate and lock the side clamp 4, the insulating plate 5 and the conductive busbar 3, completing the precise and secure installation of the entire busbar trunking.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
