AI Technical Summary
When installing on a transformer pole, it is difficult to accurately install the transformer in the middle of the support, resulting in uneven stress on the support and the pole, which affects the structural stability.
A transformer mounting bracket was designed, including two sets of clamping mechanisms and a worm gear transmission system. The worm drives the bidirectional screw to adjust the limiting plate and the C-shaped support plate, ensuring that the transformer fixed support beam is symmetrically installed in the center of the channel steel beam, thereby achieving rapid positioning and force balance of the transformer.
This technology enables rapid positioning of the transformer in the middle position above the channel steel beam, ensuring the installation balance and stress equilibrium of the support and transformer, and avoiding structural instability caused by improper positioning during long-term use.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mounting bracket technology, specifically relating to a transformer mounting bracket for power transmission and transformation projects. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).
[0003] When a transformer is installed using a pole-mounted method, it is generally necessary to install a bracket on two closely spaced utility poles and then mount the transformer on the bracket to meet the needs of outdoor overhead power distribution lines. However, during installation, the transformer needs to be installed in the middle of the top of the bracket. Otherwise, during long-term use, an imbalance will occur between the bracket and the utility poles on both sides, affecting the structural stability. However, in actual installation, it is difficult to install the transformer exactly in the middle of the bracket, making positioning quite troublesome. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a transformer mounting bracket for power transmission and transformation projects. During transformer installation, it ensures that the transformer can be quickly positioned and installed in the middle position above the channel steel beam, thereby ensuring the overall balance of the bracket and transformer installation and the balanced force distribution on the bracket. This avoids the situation where the uneven force distribution on the bracket and the power pole affects the structural stability due to the transformer not being installed in the middle position on the bracket during long-term use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer mounting frame for power transmission and transformation projects, comprising two sets of clamping mechanisms, each set of clamping mechanisms including two clamps. A first threaded plate is provided at the top of each clamp, and a U-shaped bracket is threaded onto the top of the first threaded plate. A second threaded plate is provided at the top of the U-shaped bracket, and the second threaded plate is threaded to both ends of a channel steel beam. A sliding groove is provided through the side wall of the channel steel beam, and the sliding groove is slidably connected to a slider. Limiting plates are threaded onto both the front and back of the slider, located inside one set of channel steel beams. A transmission block is fixedly installed on the side of the positioning plate. A screw mounting plate and a worm gear mounting seat are fixedly installed on the inner side of this positioning plate. The screw mounting plate is rotatably connected to a bidirectional screw. The bidirectional screw passes through the transmission block and is threadedly connected to it. A worm wheel is fixedly sleeved on the outer side of the bidirectional screw. The worm gear mounting seat is rotatably connected to a rotating shaft. A worm is fixedly sleeved on the outer side of the rotating shaft. The worm and the worm wheel mesh with each other. The side of the positioning plate located outside the channel steel beam is screwed to a C-shaped support plate. A transformer fixing support beam is screwed to the top of the C-shaped support plate.
[0006] The beneficial effects of this utility model are as follows: When installing a transformer, according to the width of the transformer, a hex wrench is inserted into the inner side of the internal hexagonal connector and rotated. This rotates the shaft along with the worm gear, which in turn drives the worm wheel to rotate, thereby driving the bidirectional screw to rotate. Through the transmission between the bidirectional screw and the transmission block, the two sets of transmission blocks move in opposite directions or in opposite directions. This, in turn, adjusts the position of the limiting plate, the U-shaped support plate, and the transformer fixing support beam, ensuring that the left and right sets of transformer fixing support beams are always symmetrical about the center of the channel steel beam. After adjusting the position of the transformer fixing support beams, the transformer can be installed. Placed on top of the transformer fixing support beam, align the screw holes on the transformer base with the bolts on the transformer fixing support beam through the slots, and then use bolts to fix them together. Since the left and right sets of transformer fixing support beams are always symmetrical about the center of the channel steel beam, the transformer can be quickly positioned and installed in the middle position above the channel steel beam. This ensures the balance of the bracket and the overall installation of the transformer, as well as the balanced force on the bracket, during installation. It avoids the situation where the uneven force on the bracket and the utility pole affects the structural stability during long-term use due to the transformer not being installed in the middle position on the bracket.
[0007] To provide enhanced support for the U-shaped bracket:
[0008] As a further improvement to the above technical solution, both clamps are provided with reinforcing support plates on their sides.
[0009] The beneficial effect of this improvement is that the reinforced support plate provides stronger support for the C-shaped bracket.
[0010] To improve the structural strength of the U-shaped support plate:
[0011] As a further improvement to the above technical solution, the inner side of the C-shaped support plate is provided with reinforcing ribs.
[0012] The beneficial effect of this improvement is that the reinforcing ribs are used to enhance the structural strength of the C-shaped support plate.
[0013] In order to rotate the shaft:
[0014] As a further improvement to the above technical solution: one end of the rotating shaft is fixed to an internal hexagonal connector.
[0015] The beneficial effect of this improvement is that the internal hex socket is used to connect with a hex wrench, thereby allowing the shaft to be rotated.
[0016] For reinforcement between the two sets of channel steel beams:
[0017] As a further improvement to the above technical solution: the side wall of the channel steel beam is provided with a screw through hole, and the inner side of the screw through hole on both sets of channel steel beams is provided with a reinforcing screw, and both ends of the reinforcing screw are threaded with nuts.
[0018] The beneficial effects of this improvement are as follows: after the reinforcing screws are passed through the screw holes on the two sets of channel steel beams, nuts are screwed in from both ends of the reinforcing screws and locked, so that the two sets of channel steel beams are further reinforced and supported.
[0019] As a further improvement to the above technical solution: the transformer fixed support beam is a hollow structure.
[0020] The transformer fixed support beam has a hollow structure, which reduces the overall weight while accommodating the bolts used to connect the transformer fixed support beam and the transformer.
[0021] As a further improvement to the above technical solution: a bolt through groove is provided between the top and bottom surfaces of the top plate of the transformer fixed support beam.
[0022] The bolts pass through slots to mate with the screw holes at the bottom of the transformer, connecting and securing the two together.
[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0031] like Figure 1-5 As shown, a transformer mounting frame for power transmission and transformation projects includes two sets of clamping mechanisms. Each set of clamping mechanisms includes two clamps 1. The top of each clamp 1 is provided with a first screw plate 3. A U-shaped bracket 4 is screwed to the top of the first screw plate 3. The top of the U-shaped bracket 4 is provided with a second screw plate 5. The second screw plate 5 is screwed to both ends of a channel steel beam 6. A sliding groove 7 is provided through the side wall of the channel steel beam 6. The sliding groove 7 is slidably connected to a slider 9. Limiting plates 10 are screwed to both sides of the slider 9. A transmission block 11 is fixedly installed on the side of the limiting plate 10 located inside one set of channel steel beams 6. The inner side of the limiting plate 10 is fixedly provided with a screw mounting plate 12 and a worm mounting seat 15. The screw mounting plate 12 is rotatably connected to a bidirectional screw 13. The bidirectional screw 13 passes through the transmission block 11 and is threadedly connected to it. A worm wheel 14 is fixedly sleeved on the outer side of the bidirectional screw 13. The worm mounting seat 15 is rotatably connected to a rotating shaft 16. A worm 17 is fixedly sleeved on the outer side of the rotating shaft 16. The worm 17 meshes with the worm wheel 14. The side of the limiting plate 10 located outside the channel steel beam 6 is screwed to a C-shaped support plate 19. A transformer fixing support beam 20 is screwed to the top of the C-shaped support plate 19.
[0032] When installing a transformer, this device, based on the transformer's width, uses a hex wrench inserted into the inner hex socket 18 and rotates it, causing the rotating shaft 16 and worm gear 17 to rotate. The worm gear 17 then drives the worm wheel 14, which in turn drives the double-acting screw 13. Through the transmission between the double-acting screw 13 and the transmission block 11, the two sets of transmission blocks 11 move towards or away from each other, thereby adjusting the position of the limiting plate 10, along with the U-shaped support plate 19 and the transformer fixed support beam 20. This ensures that the left and right sets of transformer fixed support beams 20 are always symmetrical about the center of the channel steel beam 6, thus completing the positioning of the transformer fixed support beams 20. After adjustment, the transformer can be placed on top of the transformer fixed support beam 20. Align the screw holes on the transformer base with the bolts on the transformer fixed support beam 20 through the slots 21, and then use bolts to fix them together. Since the left and right sets of transformer fixed support beams 20 are always symmetrical about the center of the channel steel beam 6, it can be ensured that the transformer can be installed in the middle position above the channel steel beam 6. This ensures the overall balance of the bracket and transformer installation and the balanced force of the bracket, avoiding the situation where the uneven force on the bracket and the pole affects the structural stability during long-term use due to the transformer not being installed in the middle position on the bracket.
[0033] Both clamps 1 have reinforcing support plates 2 on their sides.
[0034] The reinforcing support plate 2 is used to strengthen the support of the C-shaped bracket 4.
[0035] The inner side of each of the C-shaped support plates 19 is provided with reinforcing ribs 24.
[0036] The reinforcing rib 24 is used to enhance the structural strength of the C-shaped support plate 19.
[0037] One end of the rotating shaft 16 is fixed to the internal hex socket 18.
[0038] The internal hex socket 18 is used to connect to a hex wrench, thereby allowing the shaft 16 to be rotated.
[0039] The side wall of the channel steel beam 6 is provided with a screw through hole 8. The inner side of the screw through hole 8 on both sets of channel steel beams 6 is provided with a reinforcing screw 22. Nuts 23 are threaded on both ends of the reinforcing screw 22.
[0040] After passing the reinforcing screw 22 through the screw through hole 8 on the two sets of channel steel beams 6, use the nut 23 to screw it in from both ends of the reinforcing screw 22 and tighten it, so that the two sets of channel steel beams 6 are further reinforced and supported.
[0041] The transformer fixed support beam 20 has a hollow structure.
[0042] The transformer fixed support beam 20 has a hollow structure, which reduces the overall weight while accommodating the bolts used to connect the transformer fixed support beam 20 and the transformer.
[0043] A bolt through groove 21 is provided between the top and bottom surfaces of the top plate of the transformer fixed support beam 20.
[0044] The bolt passes through the slot 21 to engage with the screw hole at the bottom of the transformer, thereby connecting and fixing the two together.
[0045] The working principle and usage process of this utility model are as follows: During installation, the clamp 1 is placed on the outside of the utility pole, and bolts are used to connect and tighten the two sets of clamps 1 located on the outside of the same utility pole, fixing the clamp 1 to the outside of the utility pole. After the reinforcing screw 22 is passed through the screw through hole 8 on the two sets of channel steel beams 6, the nuts 23 are screwed in from both ends of the reinforcing screw 22 and locked, further reinforcing and supporting the two sets of channel steel beams 6. Then, according to the width of the transformer, a hex wrench is inserted into the inside of the internal hex socket 18 and rotated, driving the rotating shaft 16 and the worm gear 17 to rotate. The worm gear 17 drives the worm wheel 14 to rotate, thereby driving the bidirectional screw 13 to rotate. Through the transmission between the bidirectional screw 13 and the transmission block 11, the two sets of transmission blocks 11 move towards each other or away from each other, thereby driving the limiting plate 10 and the U-shaped support plate 19 and the transformer... The position of the transformer fixing support beam 20 is adjusted so that the left and right sets of transformer fixing support beams 20 are always symmetrical about the center of the channel steel beam 6. After the position of the transformer fixing support beam 20 is adjusted, the transformer can be placed on top of the transformer fixing support beam 20. After aligning the screw holes on the transformer base with the bolts on the transformer fixing support beam 20 through the slot 21, the two are fixed with bolts. Since the left and right sets of transformer fixing support beams 20 are always symmetrical about the center of the channel steel beam 6, it can be ensured that the transformer can be installed in the middle position above the channel steel beam 6. This ensures the balance of the overall installation of the bracket and the transformer, as well as the balanced force of the bracket. It avoids the situation where the uneven force on the bracket and the pole affects the structural stability during long-term use because the transformer is not installed in the middle position on the bracket.
