[0034] like Figures 1 to 6As shown in the figure, this utility model provides an auxiliary limiting device for transformer installation in power transmission and transformation projects, including a base plate 1. A placement plate 11 is fixedly connected to the upper surface of the base plate 1. The placement plate 11 can be used to prevent the transformer from being damaged. A movable groove 12 is provided in the placement plate 11. Two symmetrical movable plates 13 are slidably connected in the movable groove 12.

A first clamping plate 16 is fixedly connected to the upper surface of the connecting frame 15. A first bidirectional screw 17 is rotatably connected to the placement plate 11. The first bidirectional screw 17 is screwed to the movable plate 13. The rotation causes the two movable plates 13 to be screwed to the first bidirectional screw 17, thereby moving the four first guide rods 14 with their respective first clamping plates 16. The distance between the two first clamping plates 16 is adjusted to clamp and fix the two sides of the transformer. Two symmetrical stabilizing plates 18 are fixedly connected to the upper end face of the base plate 1. Two symmetrical second clamping plates 19 are movably connected to one side of the two stabilizing plates 18. A connecting plate 20 is fixedly connected to the lower end face of the second clamping plate 19. The connecting plate 20 is slidably connected to the base plate 1. A movable groove 31 is opened on the upper end face of the base plate 1. Two symmetrical movable blocks 32 are slidably connected in the movable groove 31. The movable blocks 32 are fixedly connected to the connecting plate 20. The two movable blocks 32 are screwed together with a second bidirectional screw. The second bidirectional screw 33 is rotatably connected to the base plate 1. Rotation of the second bidirectional screw 33 allows it to be screwed to two moving blocks 32, causing the two moving blocks 32 to move along with their respective connecting plates 20 and second clamping plates 19. The two second clamping plates 19 clamp and fix the other two sides of the transformer. Guide grooves 41 are provided on both sides of the base plate 1, and second guide rods 42 are slidably connected within the guide grooves 41. A stabilizing frame 43 is fixedly connected to one end of each second guide rod 42, and the stabilizing frame 43 is fixedly connected to the first clamping plate 16.

[0035] The working principle and usage process of this utility model are as follows: First, the transformer is placed on the placement plate 11. The rotation of the first bidirectional screw 17 causes it to connect with the two movable plates 13. Combined with the use of their respective first guide rods 14, the distance between the two first clamping plates 16 is adjusted to facilitate clamping and fixing the transformer on both sides. The use of the first rubber plate 61 on the first clamping plate 16 generates significant friction with the transformer body, assisting the first clamping plate 16 in fixing the transformer. Then, through the first… The rotation of the double-headed screw 33 causes the two moving blocks 32 to be screwed to the second double-headed screw 33, thereby moving the moving blocks 32 with the connecting plate 20 and the second clamping plate 19 to clamp and fix the other two sides of the transformer. This allows the hoisting equipment to connect with the four connecting ears 72, lifting the transformer and the installation auxiliary limiting device. In conjunction with the use of the positioning holes 82 on the four positioning blocks 81 on both sides of the base plate 1, the base plate 1 is fixed, thereby enabling the rapid installation and fixing of the transformer. This completes the process of using the transformer installation auxiliary limiting device in the entire power transmission and transformation project.
