Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer technology, specifically to a quick installation device for oil-immersed transformers. Background Technology

[0002] Existing oil-immersed transformers all have channel steel installed at their bottom. This channel steel is fixedly connected to the channel steel on the ground foundation to ensure the transformer's safe and stable operation. During installation, the transformer's installation position is measured and marked according to the dimensions of both the transformer's bottom channel steel and the foundation channel steel. The bolt hole positions are then marked and drilled. A crane is then used to align the holes in the oil-immersed transformer's channel steel with the holes in the foundation channel steel, and the connection is secured using connectors.

[0003] When installing an oil-immersed transformer on a foundation channel steel, it is not convenient to align the corresponding holes on the upper and lower channel steels. This requires multiple adjustments to the horizontal and vertical directions of the oil-immersed transformer when it is lifted by a crane to align the threaded holes. This installation method is inconvenient and also makes it difficult to adjust the alignment position of the oil-immersed transformer after it is lifted. Utility Model Content

[0028] As shown in the figure, Figure 6 As shown in the figure, the opposite surfaces of the two guide support plates 4 are guide surfaces, which comprise upper and lower inclined surfaces 41 and vertical surfaces 42. The inclined surface 41 is arranged upwardly inclined to one side of the end of the transverse channel steel group 3.

[0029] The bottom of the oil-immersed transformer 1 is provided with a longitudinal channel steel group 2. The vertical spacing of the two vertical surfaces 42 is adapted to the width of the longitudinal channel steel group 2. The vertical spacing of the uppermost ends of the two inclined surfaces 41 is greater than the width of the longitudinal channel steel group 2, so as to facilitate the longitudinal channel steel group to drive the oil-immersed transformer 1 to slide from top to bottom. The transverse channel steel group 3 and the longitudinal channel steel group 2 are both provided with corresponding threaded holes 6, and the threaded hole 6 of the transverse channel steel group 3 is provided with a vertical guide piece 9. As for the setting position of the guide piece 9, the lower end of the guide support plate 4 is provided with a support plate 8 which extends below the threaded hole 6 of the transverse channel steel group 3. The guide piece 9 is detachably connected with the support plate 8.

[0030] As shown in the figure, Figure 2 and Figure 6 As shown in the figure, the specific structure of the above-mentioned guide piece 9 is that the guide piece 9 comprises a conical guide section and a threaded connection section 93 which are arranged in an upper and lower distribution and are integrally formed. The maximum outer diameter of the conical guide section is smaller than the inner diameter of the threaded hole 6, and the conical guide section is used for smoothly aligning the threaded hole 6 of the longitudinal channel steel group 2 with the threaded hole 6 of the transverse channel steel group 3. The conical guide section comprises a conical tip 91 and a smooth rod section 92, and the axes of the conical tip 91 and the smooth rod section 92 are coaxial, which plays a guiding role when the threaded hole 6 of the longitudinal channel steel group 2 moves downward, so as to facilitate the smooth installation of the longitudinal channel steel on the transverse channel steel of the ground foundation; the smooth rod section 92 is located between the conical tip 91 and the threaded connection section 93, and the length of the smooth rod section 92 is smaller than the length of the threaded connection section 93. The smooth rod section 92 is shorter than the threaded connection section 93, so that when the fastening nut is threadedly connected with the threaded connection section 93, the travel of the fastening nut in the threaded connection section 93 can be reduced, and the fastening efficiency of the guide piece 9 is improved. Figure 6 It is a structural schematic view of the hidden part of the guide piece 9.

The sliding plate 7 is slidably arranged on the upper portion of the first long channel steel 31 on the outer side.

[0032] When the oil-immersed transformer 1 with the longitudinal channel steel is moved downward under the action of the crane, the longitudinal channel steel slides downward under the action of the inclined surface 41. In order to avoid that the oil-immersed transformer 1 presses and deforms or damages the guide support plate 4, a support rib plate 10 capable of supporting is arranged on one side of the guide support plate 4.

The side of the sliding plate 7 away from the guide support plate 4 is provided with a fastening screw through hole in the vertical direction. After the position of the guide support plate 4 is adjusted according to the width of the longitudinal channel steel, the fastening bolt can be screwed into the first long channel steel 31 through the fastening screw through hole, so as to realize the fixed connection between the guide support plate 4 and the first long channel steel 31. Alternatively, the through hole can be pre-formed in the first long channel steel 31 according to the final position of the fastening screw through hole. The through hole and the fastening screw through hole are arranged correspondingly, the fastening bolt can pass through the fastening screw through hole and the through hole, so as to realize the fixation of the guide support plate 4 and the first long channel steel 31, and avoid the deviation of the guide support plate 4 when the oil-immersed transformer 1 and the longitudinal channel steel are moved downward.
