[0024] In the embodiment, the hydraulic cylinder 5 is fixedly connected to the top of the bottom plate 1 at the middle of the two guide rods 2, the second sprocket 503 is arranged on the top of the hydraulic cylinder 5, and the first sprocket 502 is rotatably arranged at the bottom of the top plate 202.

[0025] In the embodiment, the chain 501 is fixedly connected to the top of the lifting frame 201 close to the hydraulic cylinder 5, and the other end of the chain 501 is fixedly connected to the bottom of the top plate 202 by passing around the first sprocket 502 and the second sprocket 503. The stroke amplification of the hydraulic cylinder 5 is realized by the arrangement of the hydraulic cylinder 5, the chain 501, the second sprocket 503, and the first sprocket 502.

[0026] In the embodiment, the first synchronous wheel 601 is rotatably connected to the both sides of the end of the top plate 202 close to the second synchronous wheel 403, and the same synchronous belt 6 is sleeved between each first synchronous wheel 601 and the adjacent second synchronous wheel 403.

At this time, the hydraulic cylinder 5 is started to retract, and the lifting frame 201 is lifted up with the lifting frame 201 and the transformer through the second sprocket 503 and the first sprocket 502. During the lifting process of the lifting frame 201, the synchronous belt 6 is moved by the fixed bar 701, thereby causing the synchronous belt 6 and the second synchronous wheel 403 to rotate. The two bidirectional screw rods 402 rotate synchronously, causing the Z-shaped rods 404 of each support mechanism 4 to move away from each other, so that the four Z-shaped rods 404 extend from the bottom of the base plate 1, thereby increasing the support area of ​​the bottom of the base plate 1. When the transformer is raised to a higher level, the center of gravity of the equipment will not be unstable, thereby improving the stability of the equipment and ensuring the safety of the transformer. When the transformer is installed, the hydraulic cylinder 5 extends, and when the lifting frame 201 descends, the synchronous belts 6 on both sides are driven to reverse, causing the Z-shaped rods 404 on both sides to retract.
