Description

Technical Field

[0001] This invention relates to the field of transformer base technology, and in particular to a transformer self-locking quick-installation base connection structure. Background Technology

[0002] As a core device for power transmission and voltage transformation in a power system, the installation stability of a transformer directly affects the safety and reliability of its operation. The base, serving as the support and fixing carrier for the transformer body, is a crucial component in the transformer installation process. In practical engineering applications, the transformer base must be firmly connected to the bottom of the transformer body to bear its weight and resist vibrations and electromagnetic forces generated during operation, preventing displacement or overturning of the transformer body and ensuring long-term stable operation of the equipment.

[0003] Currently, the connection between the transformer base and the transformer body is mostly achieved through bolt fastening. The transformer body typically has a base plate with pre-drilled bolt holes, and the base also has corresponding mounting holes. High-strength bolts are passed through these mounting holes and tightened to secure the connection. During transformer assembly, transportation, and subsequent maintenance, it is often necessary to install and disassemble the transformer body. Traditional bolt connections require tools such as wrenches to tighten and loosen the bolts, making the process cumbersome and time-consuming, and hindering the need for rapid installation and disassembly. Therefore, this invention proposes a transformer base connection structure that optimizes the connection between the transformer body bottom and the base, enabling a seamless installation of the transformer body and base while simplifying the installation and disassembly process. This meets the efficiency requirements of transformer assembly on-site and reduces equipment maintenance costs. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a transformer base connection structure. By optimizing the connection structure between the bottom of the transformer body and the base, the transformer body and the base can be fitted together for installation. At the same time, the installation and disassembly process is simplified, meeting the needs of engineering sites for transformer assembly efficiency and reducing equipment operation and maintenance costs.

[0006] As a preferred embodiment, the central support mechanism includes an adjusting gear plate rotatably mounted on the bottom of the connecting box, and adjusting gears rotatably mounted on the bottom of the connecting box and arranged in a ring, with each adjusting gear meshing with the outer side of the adjusting gear plate; a slide cylinder is fixedly mounted on the connecting box, a slide shaft is slidably fitted on the slide cylinder, a slide table is fixedly connected to the top of the slide shaft, and the slide table is fixedly connected to the central support plate.

[0007] As a preferred embodiment, the bottom end of the slide is fixedly connected with screws of the same number and position as the adjusting gears, and the screws and the adjusting gears form a helical pair.

[0008] As a preferred embodiment, a support rod is telescopically provided on the outer side of the base, the push plate has a Z-shaped structure, and a spring is connected between the push plate and the lower end face of the base for passing elastic force; a mating shaft is fixedly connected to the push plate, the mating shaft is slidably mated on the base, and a lifting rod is fixedly connected to the top of the mating shaft. By lifting the push plate, the push plate pushes the control mechanism on the outer support mechanism, and the support rod telescopically moves towards the inner side of the base to support and fix the lifting rod.

[0009] As a preferred embodiment, the base has the same number of assembly holes as the outer support mechanism, and the assembly cylinder on the outer support mechanism is fitted into the assembly holes; a position cylinder is fixedly installed on the assembly cylinder, the inner side of the position cylinder has a second threaded part, the lower end of the position cylinder has a first threaded part, and the bottom area of ​​the assembly cylinder has a fourth threaded part; the bottom end of the mounting base has a third threaded part, which is threaded with the second threaded part to adjust the installation spacing.

[0010] As a preferred embodiment, an adjusting seat 1 is installed on the threaded part 1 with a threaded engagement, and an adjusting seat 2 is installed on the threaded part 4 with a threaded engagement, so that the assembly cylinder is fixed on the base by adjusting seat 1 and adjusting seat 2.

[0011] As a preferred embodiment, the control mechanism includes a push shaft that is slidably installed inside the assembly cylinder.

[0013] The beneficial effects of this invention compared with the prior art are: (1) In this invention, the adjusting seat can also be adjusted axially to adjust the axial installation position of the assembly cylinder. For example, if the transformer needs to be finely adjusted in the height direction, the axial installation position of the assembly cylinder can be adjusted; (2) The mounting holes on the transformer base plate correspond to each positioning cylinder in sequence. The positioning cylinder passes through the mounting hole, and the buckle is squeezed by the inner side of the mounting hole and shrinks inward.

That is, by rotating the mounting seat, the axial position of the mounting seat can be adjusted, thereby adjusting the spacing between the mounting rubber pad and the lower end face of the buckle to match the thickness of the transformer base plate; (4) When it is necessary to replace the mounting rubber pad or rubber pad, it can be replaced by alternating support. When replacing, the alternating support is temporary. With the external assistance of the operator, the stability of the transformer during replacement can be guaranteed. Attached Figure Description

The buckle 26 can be fastened and fixed to the mounting hole on the bottom outer side of the transformer 1. An mounting seat 20 is axially slidably provided on the assembly cylinder 22. A mounting rubber pad 21 is attached to the top of the mounting seat 20. The mounting hole on the bottom outer side of the transformer 1 is fixed between the mounting rubber pad 21 and the buckle 26. A control mechanism is slidably provided inside the assembly cylinder 22 to control the radial telescopic movement of the buckle 26. A push plate 12 is slidably provided on the base 2 and below each outer support mechanism to push the control mechanism.

[0027] The central support mechanism includes an adjusting gear disk 10 rotatably mounted at the bottom of the connecting box 5, and adjusting gears 11 rotatably mounted at the bottom of the connecting box 5 and arranged in a ring. Each adjusting gear 11 meshes with the outer side of the adjusting gear disk 10. A slide cylinder 8 is fixedly mounted on the connecting box 5, and a slide shaft 7 is slidably fitted on the slide cylinder 8. A slide table 6 is fixedly connected to the top of the slide shaft 7, and the slide table 6 is fixedly connected to the central support plate 3. The bottom of the slide table 6 is fixedly connected with screws 9 of the same number and position as the adjusting gears 11. The screws 9 and the adjusting gears 11 form a helical pair.

[0028] A support rod 16 is telescopically installed on the outer side of the base 2. The push plate 12 has a Z-shaped structure. A spring 13 is connected between the push plate 12 and the lower end face of the base 2 to allow for the transmission of elastic force. A mating shaft 14 is fixedly connected to the push plate 12. The mating shaft 14 is slidably mated to the base 2. A lifting rod 15 is fixedly connected to the top of the mating shaft 14. By lifting the push plate 12, the push plate 12 pushes the control mechanism on the outer support mechanism. The support rod 16 telescopically moves towards the inner side of the base 2 to support and fix the lifting rod 15.

[0029] The base 2 has the same number of assembly holes 201 as the outer support mechanism. The assembly cylinder 22 on the outer support mechanism is installed in the assembly holes 201. A position cylinder 17 is fixedly installed on the assembly cylinder 22. The inner side of the position cylinder 17 has a second threaded part 1702. The lower end of the position cylinder 17 has a first threaded part 1701. The bottom area of ​​the assembly cylinder 22 has a fourth threaded part 2201. The bottom end of the mounting seat 20 has a third threaded part 2001. The third threaded part 2001 is threaded with the second threaded part 1702 to adjust the installation spacing. An adjustment seat 18 is threadedly installed on the first threaded part 1701. An adjustment seat 29 is threadedly installed on the fourth threaded part 2201. The assembly cylinder 22 is fixed on the base 2 by the adjustment seats 18 and 29.

[0030] The control mechanism includes a push shaft 24 slidably installed inside the assembly cylinder 22. The inner circumference of the assembly cylinder 22 is provided with a cross groove structure, and the push shaft 24 cooperates with the inside of the assembly cylinder 22 through the cross groove structure. A push seat 25 is fixedly provided at the bottom end of the push shaft 24, and a push wheel 27, the same number as the buckle seat 26, is fixedly provided at the top end of the push shaft 24. The push wheel 27 is used to push and control the buckle seat 26 to move radially. The buckle seat 26 is provided with a slope structure at the top. A spring 28 for providing elastic force is connected between the end of the buckle seat 26 facing the inside of the positioning cylinder 23 and the positioning cylinder 23. A push rod 29 is fixedly provided at the bottom end of the buckle seat 26. The push rod 29 is provided with a slope area, and the slope area is pushed by the push wheel 27.

[0031] The working principle is as follows: According to the size of the transformer 1 base plate and the number of mounting holes, a corresponding number of assembly holes 201 can be opened on the base 2. The drilling operation is simple and the processing cost is low. The size of the assembly hole 201 is adapted to the assembly cylinder 22. By rotating the adjustment seat 2 19, the assembly cylinder 22 can be fixed on the base 2 using the adjustment seat 2 19 and the adjustment seat 1 18. Specifically, the adjustment seat 1 18 can also be adjusted axially to adjust the axial installation position of the assembly cylinder 22. If the transformer needs to be finely adjusted in the height direction, the axial installation position of the assembly cylinder 22 can be adjusted.

[0032] Furthermore, after installing each assembly cylinder 22 onto the base 2, the transformer 1 is installed onto the base 2. The mounting holes on the base plate of the transformer 1 correspond sequentially to each positioning cylinder 23. The positioning cylinder 23 passes through the mounting hole, and the buckle 26 is squeezed inward by the inner side of the mounting hole. After passing through the mounting hole, it moves outward to achieve self-locking of the base plate of the transformer 1, without the need for manual subsequent locking operations. Specifically, the installation spacing can be adjusted according to the installation thickness of the base plate of the transformer 1. That is, by rotating the mounting seat 20, the axial position of the mounting seat 20 is adjusted, thereby adjusting the spacing between the mounting rubber pad 21 and the lower end face of the buckle 26 to adapt to the thickness of the base plate of the transformer 1.

[0033] After the outer area of ​​the base plate of transformer 1 is positioned and fixed, the adjusting gear 10 is rotated to make each adjusting gear 11 rotate. Under the connection of the screw pair, each screw 9 moves, and the screw 9 drives the central support plate 3 to move, so that the rubber pad 4 contacts the center area of ​​the bottom of transformer 1, thereby achieving support. In conjunction with the positioning and fixing of each mounting hole, the transformer 1 is stably installed. Among them, the rubber pad 21 and the rubber pad 4 are in direct contact with the base plate of transformer 1, which can buffer vibration.

[0034] Furthermore, for different models of transformer 1, after the assembly cylinder 22 is pre-installed on the base 2, it is not necessary to remove the assembly cylinder 22 later. However, when it is necessary to remove the transformer 1, the lifting rods 15 can be lifted and moved to move the push plate 12 upward. The push plate 12 pushes the push seat 25 to move the push shaft 24. The push wheel 27 at the top of the push shaft 24 moves the inclined area on the push rod 29, causing the buckle 26 to retract radially. At the same time, the support rod 16 is pushed towards the inside of the base 2, so that the support rod 16 is located below the lifting rod 15, thereby supporting and fixing the lifting rod 15. The push plate 12 always maintains the pushing state on the push shaft 24. After the buckles 26 on each side have completed radial retraction, the connection between the transformer 1 and the base 2 is released.

[0035] Furthermore, after prolonged use, the vibration damping effect of rubber pads 21 and 4 will decrease. When it is necessary to replace rubber pads 21 or 4, they can be replaced by alternating support methods. Specifically, first, only the outer side of the transformer 1 base plate is supported and fixed. By rotating the adjusting gear 10, the central support plate 3 is lowered into the connecting box 5 to replace the rubber pad 4. That is, the operator uses a removal tool to remove the rubber pad 4 from the central support plate 3, and then uses an adhesive to reattach the unused rubber pad 4, completing the replacement process. Replacement; move the control center support plate 3 so that the rubber pad 4 re-contacts the support on the transformer 1 base plate. Following the aforementioned process, the buckle 26 is radially retracted to release the fixed state with the transformer 1 base plate. Then, by adjusting the height of the center support plate 3, the position of the transformer 1 is finely adjusted so that the operator can replace the installed rubber pad 21. Furthermore, by using alternating support, the installed rubber pad 21 and rubber pad 4 can be replaced. During replacement, the alternating support is temporary. With the external assistance of the operator, the stability of the transformer 1 during replacement can be ensured.

[0036] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
