[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly used for voltage conversion, current conversion, and voltage stabilization. To manufacture a transformer, you need to first manufacture various components and then assemble them. During the assembly process, due to the numerous steps, the transformer must be frequently hung and moved back and forth. Most of the existing transformer hanging devices have a single connection point, which will inevitably cause a certain degree of shaking and extremely unstable lifting. At the same time, due to the different brands and types of transformers, the positions of the lifting ears are not the same, so it is difficult to hang all types of transformers.

One end of the two groups of hanging ropes 16 away from the winding wheel 15 is connected to a lifting plate 9, and a hanging unit is connected to the bottom of the lifting plate 9. The hanging unit includes a hook 24, and a transformer 8 is arranged below the hook 24. Four groups of hanging ears 21 are fixedly connected to the top of the transformer 8, and the four groups of hanging ears 21 are hung with the hook 24. Because the transmission wheel and the transmission belt are designed according to the rack and toothed chain, the torsional friction force is increased. When the forward and reverse motor 12 starts to operate, the connecting shaft 20 rotates forward, which drives the toothed sprocket wheel 18 and the belt 19 to twist in the clockwise direction, thereby generating a force to wrap around the hanging rope 16 of the winding wheel 15 body, and the transformer 8 under the hanging unit is lifted. The connecting shaft 20 reverses, which drives the toothed sprocket wheel 18 and the belt 19 to twist in the counterclockwise direction, thereby generating a force to retract and release the hanging rope 16 of the winding wheel 15 body, and the transformer 8 under the hanging unit is lowered.
[0021] See also Figure 4 , Figure 6 and Figure 7 , the bottom surface of the lifting plate 9 is provided with multiple groups of longitudinal and transverse grooves, and the inner wall of the longitudinal and transverse grooves is provided with multiple groups of guide rail grooves, and four groups of sliding blocks 22 are slidably connected inside the longitudinal and transverse grooves, and the bottom end of the sliding block 22 is connected to the wire rope 23, and the bottom of the wire rope 23 is connected to the top of the hook 24. The upper part of the sliding block 22 is an annular convex shape, and is slidably connected to the multiple groups of guide rail grooves in the multiple groups of longitudinal and transverse grooves. The annular convex part plays a fixing effect in the multiple groups of longitudinal and transverse grooves. The hook 24 is connected to the four groups of lifting ears 21 on the top of the transformer 8 through the wire rope 23, so that the hook 24 has swing flexibility, hooking the four groups of lifting ears 21 on the top of the transformer 8. According to the different positions of the top lifting ears 21 of the transformer 8 of different brands and types, the distance between the four groups of sliding blocks 22 in the multiple groups of longitudinal and transverse grooves and the mutual spacing between the hooks 24 can also be adjusted;
[0022] See also Figure 1 , Figure 2 and Figure 3 Two sets of transverse grooves 14 are provided on the front side of the top of the auxiliary frame 5, and three sets of moving wheels 17 are evenly connected to the left and right sides of the bottom of the sliding frame 6. When the hydraulic push rod 7 is running, it provides the force of pushing forward and pulling back backward, so that the sliding frame 6 can move forward and backward, and adjust the front and rear distance of the transformer 8 in the air. The design of the transverse grooves 14 and the moving wheels 17 is to help the sliding frame 6 to move easily and avoid damage caused by long-term friction between the sliding frame 6 and the auxiliary frame 5. Two sets of guide rods 10 are connected between the top of the counterweight bottom box 2 and the bottom of the auxiliary frame 5. The two sets of guide rods 10 are respectively located on the left and right sides of the support column 4. Two sets of stabilizing rods 13 are connected to the rear side of the lifting plate 9. The body of the stabilizing rod 13 is provided with strip holes. The two sets of guide rods The rod 10 is located inside the two groups of strip holes. When the lifting plate 9 is lifted up and down, the stabilizing rod 13 is limited by the strip holes of the main body and is lifted straight up and down along the guide rod 10, so that the transformer 8 and the lifting ear 21 hung by the hook 24 will not shake violently when they move up and down, thereby ensuring stability. A counterweight block 3 is placed on the rear side of the top of the mobile base 1, and the front side of the counterweight block 3 is located on the rear side of the counterweight bottom box 2. When the hydraulic push rod 7 pushes the sliding frame 6 forward, the moment of the force arm tends to increase forward, and it is difficult to ensure that the center of gravity is not lost. The counterweight block 3 is added to the counterweight bottom box 2 to balance the torque of the overall structure. Through holes are opened at the four corners of the edge of the mobile base 1, and a bottom bracket 11 is screwed inside the through hole to play a role in anti-slip and stabilization.
[0023] Working principle: When the new solution is implemented, the mobile base 1 is pushed to the transformer 8 to be hung, and the four sets of bottom brackets 11 chassis are placed on the ground. The upper screw block of the bottom bracket 11 is loosened, and the lower screw block of the bottom bracket 11 is tightened to support the mobile base 1 to stabilize it. A hook 24 is connected under the sliding block 22 through a wire rope 23, so that the hook 24 has swing flexibility and is hooked to the four sets of ears 21 on the top of the transformer 8. The positions of the top ears 21 of transformers 8 of different brands and types are different, and the distances between the four sets of sliding blocks 22 in multiple sets of vertical and horizontal grooves and the mutual spacing between the hooks 24 can also be adjusted. After starting the forward and reverse motor 12, the connecting shaft 20 rotates forward, which drives the sprocket 18 and the belt 19 to twist in the clockwise direction, thereby generating a force to wrap around the main body of the winding wheel 15 The rope 16 is used to lift the transformer 8 under the hanging unit, and the connecting shaft 20 is reversed. The gear sprocket 18 and the belt 19 are driven to twist in the counterclockwise direction, thereby generating the force of the main body suspension rope 16 of the reel 15 to lower the transformer 8 under the hanging unit. When the lifting plate 9 is lifted up and down, the stabilizing bar 13 is limited by the strip hole of the main body and is lifted straight along the guide rod 10, so that the transformer 8 and the lifting lug 21 connected with the hook 24 will not shake violently when they move up and down, thereby ensuring stability. When the hydraulic push rod 7 is running, it provides the force of pushing forward and pulling back backward, so that the sliding frame 6 can move forward and backward, and adjust the front and rear distance of the transformer 8 in the air. The design of the transverse groove 14 and the moving wheel 17 is to help the sliding frame 6 to move easily and avoid damage caused by long-term friction between the sliding frame 6 and the auxiliary frame 5. When the hydraulic push rod 7 pushes the sliding frame 6 forward, the moment of the force arm tends to increase forward, and it is difficult to maintain the center of gravity. After adding the counterweight block 3 to the counterweight bottom box 2, the torque effect of the overall structure is balanced.
