Description

Technical Field

[0001] This utility model provides a reinforced connection structure for tubular busbar bridges, belonging to the technical field of power transmission and distribution equipment. Background Technology

[0002] Tubular busbars, also known as tubular busbars, are a type of high-current transmission conductor widely used in modern power systems. They are widely used in power plants, substations, and large industrial and mining enterprises as a replacement for traditional rectangular busbars or cables due to their significant advantages such as high current carrying capacity, low skin effect, good heat dissipation, high mechanical strength, reliable electrical insulation performance, and large installation span.

[0003] During the installation of tubular busbars, they are typically placed on cable trays or supports along the route. To ensure the safety and stability of the busbars during long-term operation, reliable connection structures must be used to secure them to the cable trays or supports.

[0004] The existing fixing methods can basically meet normal usage needs, but they still have the following shortcomings:

[0005] The fixing method is simple and the stability is poor: Traditional fasteners mostly use simple U-shaped clamps or unidirectional clamps. This structure mainly provides vertical constraint force and has weak lateral support and limiting ability. Tubular busbars are prone to lateral swaying or axial movement in the clamp.

[0006] Inconvenient adjustment and low installation efficiency: Most existing fixed structures require the use of multiple tools for fastening and adjustment, the operating space is limited, the adjustment process is cumbersome, and it is difficult to quickly and accurately adjust the clamping force or busbar position during on-site installation or later inspection and maintenance, resulting in low construction and maintenance efficiency.

[0007] Based on this, the present invention provides a reinforced connection structure for tubular busbar cable trays. Utility Model Content

[0008] The technical problems solved by this utility model are: the fixing method is singular and the stability is poor. The tubular busbar is prone to lateral swaying or axial movement, which causes displacement and loosening of the tubular busbar; the adjustment is inconvenient and the installation efficiency is low. Multiple tools are required for fastening and adjustment, resulting in low work efficiency.

[0009] To solve the technical problem, the technical solution provided by this utility model is: a reinforced connection structure for a tubular busbar cable tray, comprising:

[0010] The support has a cover plate on its top;

[0011] A locking assembly installed in the support is used to clamp the tubular busbar, including a base plate, a C-shaped frame fixedly installed in the middle of the top of the base plate, and an upper clamping block slidably connected to the inner wall of the C-shaped frame;

[0012] A reinforced support assembly is used to assist in locking the support of the tubular busbar, including a pair of clamps symmetrically located on both sides of the C-frame and slidably connected to the top of the base plate.

[0013] Furthermore, the base plate has several mounting holes symmetrically arranged on both sides of its top, and the base plate is fixedly installed at the bottom of the support by bolts passing through the mounting holes.

[0014] Furthermore, the locking assembly also includes a screw threaded to the top of the C-frame, one end of which is rotatably connected to the top of the upper clamping block, and the other end of which is provided with a handwheel.

[0015] Furthermore, the reinforcing support assembly also includes a connecting lug fixedly disposed on the top of the clamp, and a threaded rod passing through the connecting lug is provided above the clamp on the same side, and a wing nut that fits against the side wall of the connecting lug for locking the clamp is threaded onto the threaded rod.

[0016] Furthermore, the bottom of the C-shaped frame, the bottom of the upper clamping block, and the side walls of the clamping support that are close to each other are all provided with arc-shaped grooves that match the outer diameter of the tubular busbar, and the inner wall of the arc-shaped grooves is provided with rubber pads.

[0017] Furthermore, the inner sidewall of the C-shaped frame is symmetrically provided with limiting grooves that match the sidewall of the upper clamping block.

[0018] The beneficial effects of this utility model are:

[0019] By using locking components and reinforcing support components to securely fix the tubular busbar, a stable locking mechanism is achieved to prevent lateral swaying or axial movement of the tubular busbar, thus preventing displacement and loosening. The mechanism is easy to adjust and quick to operate. Installation or maintenance personnel can clamp, loosen, and adjust the lateral support of the tubular busbar without complicated tools, significantly improving work efficiency.

[0026] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0027] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] According to the appendix Figure 1 , 3 As shown in Figure 4, this utility model provides a reinforced connection structure for a tubular busbar cable tray: a support 1, with a cover plate 6 fixed to the top of the support 1 by bolts, the support 1 and the cover plate 6 forming a hollow tubular busbar receiving channel; a locking component 2 set inside the support 1 for clamping the tubular busbar, including a base plate 3, a C-shaped frame 4 fixedly set in the middle of the top of the base plate 3, and an upper clamping block 5 slidably connected to the inner side wall of the C-shaped frame 4. The inner side wall of the C-shaped frame 4 is symmetrically provided with limiting grooves 16 that match the side wall of the upper clamping block 5, which play a limiting role. The locking component 2 also includes a screw 10 threadedly connected to the top of the C-shaped frame 4. One end of the screw 10 is rotatably connected to the top of the upper clamping block 5, and the other end of the screw 10 is provided with a handwheel. Specifically, by rotating the handwheel, the operator can easily drive the screw 10 to rotate, and use the threaded transmission to make the upper clamping block 5 move smoothly up and down in the vertical direction, thereby realizing the clamping or loosening of the tubular busbar. The operation is intuitive and labor-saving.

[0029] As per the instruction manual Figure 1 , 2 As shown in Figure 4: The reinforcing support assembly 7 is used to assist the locking assembly 2 in supporting the tubular busbar. It includes a pair of clamps 8 symmetrically located on both sides of the C-frame 4 and slidably connected to the top of the base plate 3. The reinforcing support assembly 7 also includes a connecting lug 11 fixedly set on the top of the clamps 8. A threaded rod 12 is provided above the clamps 8 on the same side, passing through the connecting lug 11. A wing nut 13 is threaded on the threaded rod 12 and fits against the side wall of the connecting lug 11 to lock the clamps 8. Specifically, when providing lateral support, by rotating the wing nut 13, the clamps 8 slide along the base plate 3 towards the middle and press against the tubular busbar, thereby providing a stable lateral support force and preventing the tubular busbar from swaying laterally. The design of the wing nut 13 makes the operation convenient and quick without the need for special tools.

[0030] As per the instruction manual Figure 1 , 4 As shown: Several mounting holes 9 are symmetrically arranged on both sides of the top of the base plate 3. The base plate 3 is fixed to the bottom of the support 1 by bolts passing through the mounting holes 9. The bottom of the C-shaped frame 4, the bottom of the upper clamping block 5, and the side walls of the clamping support 8 that are close to each other are all provided with arc-shaped grooves 14 that match the outer diameter of the tubular busbar. The inner wall of the arc-shaped groove 14 is provided with rubber pads 15. Specifically, the corresponding C-shaped frame 4, upper clamping block 5, and clamping support 8 are selected according to the specifications of the tubular busbar. The design of the arc-shaped groove 14 makes the clamping parts fit with the surface of the tubular busbar in an arc shape, increasing the contact area and making the clamping force distribution more uniform. The rubber pads 15 are preferably made of nitrile rubber or EPDM rubber that are resistant to aging, high and low temperatures, and have good elasticity. Their thickness is about 3-5mm. The setting of the rubber pads 15 can protect the insulation layer on the surface of the tubular busbar from scratches or pressure damage. On the other hand, its elasticity can play a role in buffering and shock absorption and increasing friction, further enhancing the reliability of the fixation.

[0031] As an optional embodiment, those skilled in the art can obtain the following based on their own knowledge and common sense: for the problem of dust and rust on exposed screws and lead screws, the dust can be cleaned regularly, and rust can be prevented by means of galvanizing or coating to increase service life. When the rust becomes so bad that it cannot be used, it can be replaced.

[0032] The principle of this utility model

[0033] During installation, the base plate 3 is fixed in a suitable position at the bottom of the support 1 using bolts passing through the mounting holes 9. Then, the tubular busbar is placed in the arc-shaped groove 14 at the bottom of the C-frame 4. Then, the handwheel is turned clockwise to make the screw 10 drive the upper clamping block 5 downward until the arc-shaped groove 14 at its bottom presses against the top of the tubular busbar. Appropriate preload is applied to lock the position of the tubular busbar. Next, the wing nuts 13 on both sides are screwed on to make the two clamping supports 8 slide towards the middle until the rubber pads 15 on their sides are pressed against both sides of the tubular busbar to assist in supporting the tubular busbar. At this point, the tubular busbar is firmly locked in both the vertical and horizontal directions. Finally, the cover plate 6 is put on and tightened with bolts to complete the installation.

[0034] In summary, this utility model features a robust structure and dual locking mechanism: the locking component 2 provides strong vertical clamping of the tubular busbar, while the reinforcing support component 7 offers auxiliary support and locking on both sides. Furthermore, the arc-shaped groove and rubber pads provide uniform and buffered contact. This dual locking method of vertical clamping and horizontal support significantly improves the reliability of the tubular busbar's fixation, preventing lateral swaying or axial movement, and preventing displacement and loosening. It is also convenient and quick to adjust: the locking component 2 uses a handwheel and screw, and the reinforcing support component 7 uses a wing nut and lead screw, both enabling quick and effortless manual adjustment. Installation and maintenance personnel can clamp, loosen, and adjust the lateral support of the busbar without complex tools, significantly improving work efficiency.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
