Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transformer support technology, specifically to a transformer body clamping device for a double-body product with a large volume difference. Background Technology
[0002] As transformer structures become increasingly compact, especially in traction transformers, the capacity difference between the two transformer bodies is widening, leading to a greater difference in their volume. This results in the emergence of small and large transformer bodies. In some regions, to improve the efficiency and stability of substations, small and large transformer bodies are used together. Due to the significant volume difference between the small and large transformer bodies, a clamping structure is often installed on the top of the small transformer body to ensure that the top cover of both bodies remains flat.
[0003] In the existing technology, the height of the clamping structure is fixed. During the installation process, the clamping structure of different heights is replaced to make the top cover of the small and large transformer bodies flat. This installation process is inefficient and puts a lot of work on the installers. The clamping structure cannot be adjusted in height, which cannot meet the requirement of adjusting the height of the top cover of the small transformer body. This results in poor flatness of the installed cover, which affects the stability and reliability of the transformer. Utility Model Content

The rotating sleeve is sleeved on the threaded rod and is threadedly connected to the threaded rod. The outer wall of the slide cylinder has a guide groove, and the rotating sleeve extends out of the slide cylinder through the guide groove.
[0012] Preferably, a first support plate is provided at the bottom end of the guide sleeve, and the first support plate is installed at the bottom of the small body.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:
[0019] This utility model proposes a clamping device for a double-body product with a large volume difference. This device can adjust the height of the docking base plate through the adjustment component, and then adjust the height of the top cover of the small body, so that the flatness of the cover connecting the small body and the large body reaches the preset flatness requirement. At the same time, it makes the center of gravity of the small body and the large body basically the same, and keeps the top cover of the small body and the large body flat, increasing the wiring space above the small body and the large body and reducing production costs.
[0020] Furthermore, the device connects the top of the smaller unit to the adjustment section via a first support plate, increasing the stability of the adjustment section and reducing wear between the adjustment section and the top surface of the smaller unit, thus facilitating maintenance and replacement. The larger unit also uses a support plate to reduce wear on the cover, increasing its service life.
[0021] Furthermore, this device connects the box cover via a connecting plate, enhancing the structural stability of the entire clamping device and ensuring stable performance under various working conditions. It also facilitates assembly and maintenance, optimizes space utilization, and enhances the adaptability of the equipment.
[0022] Furthermore, by setting wooden blocks in this device, vibrations and impacts from inside or outside the vessel can be effectively absorbed and dispersed, reducing the transmission of vibrations and impacts between the lid and the vessel body, protecting key internal components from damage, and extending the service life of the vessel body. By adjusting the thickness and position of the wooden blocks, the flatness of the lid on the vessel body can be further fine-tuned, so that the height and balance of the lid reach the preset height.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] See Figures 1-3 This utility model proposes a body clamping device for dual-body products with large volume differences. The device includes an adjustment part installed on the top end face of the smaller body 9. The top of the adjustment part is connected to one end of the cover 8, and the other end of the cover 8 is connected to the larger body 10. By adjusting the adjustment part, the center of gravity of the smaller body 9 and the larger body 10 are basically consistent, and the top cover 8 of the smaller body 9 and the larger body 10 is kept flat, increasing the wiring space above the smaller body 9 and the larger body 10 and reducing production costs.
[0034] See Figures 1-3 The adjustment unit includes a docking base plate 4. A wooden pad 2 is installed on the top end face of the docking base plate 4. Multiple guide members 3 are connected to the bottom end face of the docking base plate 4. In this embodiment, four guide members 3 are provided. The four guide members 3 are evenly distributed on the bottom end face of the docking base plate 4, and the four guide members 3 are equally spaced around the center of the docking base plate 4. Each guide member 3 includes a slide cylinder 30. One end of the slide cylinder 30 away from the opening is fixed to the bottom end face of the docking base plate 4. A guide sleeve 31 is installed inside the slide cylinder 30, and one end of the guide sleeve 31 is fixed to the support plate 1. An adjusting component 5 is installed inside the guide sleeve 31. One end of the adjusting component 5 is fixed inside the slide cylinder 30 near the end face of the docking base plate 4. By adjusting the adjusting component 5, the slide cylinder 30 can be pushed to move back and forth along the guide sleeve 31, thereby causing the docking base plate 4 to move up and down above the support plate 1. Adjusting the height position of the docking base plate 4 realizes the adjustment of the height position of the connecting plate 7 connected to the top of the small body 9, so that the connecting plate 7 at the top of the small body 9 and the connecting plate 7 at the top of the large body 10 are at the same height, ensuring that the box cover 8 connected by the two connecting plates 7 is flat.
[0035] See Figure 2 The adjusting component 5 includes a threaded rod 50, which is vertically installed inside the guide sleeve 31, with the axis of the threaded rod 50 collinear with the axis of the guide sleeve 31. The top end of the threaded rod 50 is fixed inside the slide cylinder 30 near the end face of the docking base plate 4. An installation groove is provided on the outer wall of the guide sleeve 31 near its top end face, and a rotating sleeve 51 is installed in the installation groove. The rotating sleeve 51 is sleeved on the threaded rod 50 and is threadedly connected to the threaded rod 50. By rotating the rotating sleeve 51, the threaded rod 50 can move along the axial direction of the guide sleeve 31 inside the guide sleeve 31, thereby pushing the slide cylinder 30 to move vertically on the support plate 1. A guide groove 32 is provided on the outer wall of the slide cylinder 30 corresponding to the position of the rotating sleeve 51. The guide groove 32 is provided along the length direction of the guide sleeve 31, and the inner side of the guide groove 32 extends into the interior of the slide cylinder 30. The rotating sleeve 51 extends to the outside of the slide cylinder 30 through the guide groove 32, making it convenient for operators to use.
[0036] See Figure 3 A mounting plate 33 is provided on the outer wall of the slide cylinder 30 near its bottom end. A through hole is provided on the upper end face of the mounting plate 33, and a fixing member 6 is threadedly connected to the through hole. A connecting hole is provided on the upper end face of the support plate 1 corresponding to the through hole. One end of the fixing member 6 passes through the through hole and connects to the connecting hole on the support plate 1, and the connecting hole is threadedly connected to the lower end of the fixing member 6. When the slide cylinder 30 is adjusted to the moving height by the adjusting member 5, the self-locking of the adjusting member 5 and the fixing member 6 can fix the adjusted height position of the docking base plate 4, increasing the stability of the device. In this embodiment, the fixing member 6 is a bolt.
[0037] See Figures 1-3 A first support plate 1 is installed on the bottom end face of the guide sleeve 31. The first support plate 1 is fixed to the top end face of the small body 9. A second support plate 11 is installed on the top end face of the large body 10 at the connection with the box cover 8. The top of the small body 9 is connected to the guide sleeve 31 through the first support plate 1, which increases the stability of the support for the guide sleeve 31. At the same time, it reduces the wear between the guide sleeve 31 and the top end face of the small body 9, and makes the guide sleeve 31 and the small body 9 detachable, thereby facilitating maintenance and replacement. The second support plate 11 on the large body 10 reduces the wear of the box cover 8 on the body and increases its service life.
[0038] See Figures 1-3 A connecting plate 7 is installed on the top end face of the docking base plate 4. A connecting plate 7 is also installed above the support plate 1 installed on the top end face of the main body 10. The connecting plate 7 connects to the box cover 8. The connecting plate 7 enhances the structural stability of the clamping device, enabling it to maintain stable performance under various working conditions. At the same time, it facilitates assembly and maintenance, optimizes space utilization, and enhances the adaptability of the equipment.
[0039] See Figures 1-3 Wooden blocks 2 are provided at the top of the small body 9, which is located between the top end face of the docking base plate 4 and the connecting plate 7, and at the top of the large body 10, which is located between the second support plate 11 and the connecting plate 7. The wooden blocks 2 can effectively absorb and disperse vibration and impact from inside or outside the body, reduce the transmission of vibration and impact between the cover 8 and the body, protect the key components inside the body from damage, and extend the service life of the body. At the same time, by adjusting the thickness and position of the wooden blocks 2, the flatness of the cover 8 on the body can be further fine-tuned so that the height and balance of the cover 8 reach the preset height.
