When the telescopic cylinder is extended, the connecting plate is pushed to rise. Under the restriction of the fixed seat, the rising connecting plate drives the movable rod to deflect, and the top of the movable rod pushes the cross bars on both sides away from each other. At this time, the displacement adjustment seats at both ends of the cross bar slide along the inner wall of the fixed seat.

This can ensure that the support block will not deflect excessively when it pops up, and can support the bottom of the power transformer at a suitable angle.
[0008] Preferably, the lifting device includes a protective shell, both sides of the protective shell are rotatably connected to guide wheels, the top of the protective shell is fixedly connected to a buffer assembly, the bottom of the protective shell is provided with a side fixing plate, the outer side of the side fixing plate is rotatably connected to a rotating shell, the inner side of the rotating shell is fixedly connected to a sling, the top of the sling is fixedly connected to a connecting rod, and the center of the connecting rod is fixedly connected to a lifting ring. When the crane lifts the device as a whole through the lifting device, the hook pulls the connecting rod upward through the lifting ring, and at this time the connecting rod drives the four slings on both sides thereof to move upward, and lifts the entire device upward through the rotating shell and the side fixing plates.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides an adjustment device. When the telescopic cylinder is extended, the connection plate is pushed up. Under the restriction of the fixed seat, the connection plate rises and drives the movable rod to deflect. The top of the movable rod pushes the cross bars on both sides away from each other. At this time, the displacement adjustment seats at both ends of the cross bar slide along the inner wall of the fixed seat. The movement of the displacement adjustment seat drives the fixed device fixedly connected thereto to adjust its position, thereby adapting to power transformers of different sizes.
[0014] 2. The present invention sets a fixing device and an adjusting device to cooperate with each other. After the position of the fixing device is adjusted to a size suitable for the power transformer, the crane drives the device to move downward as a whole, so that the lateral clamping plate contacts the side wall of the power transformer, and then the telescopic cylinder contracts, and finally drives the displacement adjustment seats on the front and rear sides to approach each other, thereby making the lateral clamping plates approach each other and clamping the power transformer.
[0015] 3. The present invention sets a load-bearing assembly. When the power transformer is lifted by a crane and the lifting device, the hydraulic telescopic rod drives the limit slider to slide downward along the inner wall of the lateral clamping plate, so that the limit slider drives the load-bearing assembly to move downward through the sliding rod. When the load-bearing assembly is separated from the side wall of the power transformer, the elastic force of the torsion spring is released, and the limit arc plate is deflected under the limitation of the annular fixed plate. At this time, the limit arc plate drives the limit rod and the assembly plate to drive the support block to deflect along the fixed rod, thereby allowing the support block to automatically pop out of the shell.
[0016] 4. The present invention provides a hydraulic telescopic rod, which can drive the bearing assembly to move up and down, so that the support block can be adjusted according to the power transformers of different heights. This flexibility allows the hoisting device to adapt to power transformers of various sizes, improving the versatility of the device. By providing a booster wheel, after the hoisting is completed, the booster wheel can provide rolling support during the withdrawal process of the support block, making the movement of the support block smoother.
[0017] 5. The present invention sets a limit rod and limits the movement of the limit rod through the arc hole, thereby limiting the maximum deflection angle of the support block. This can ensure that the support block will not deflect excessively when it pops up, and can support the bottom of the power transformer at a suitable angle. Regardless of how the size of the transformer changes, the support effect of the support block can be guaranteed to be stable and reliable.
[0018] 6. The present invention is provided with a lifting device. When the crane lifts the entire device through the lifting device, the hook pulls the connecting rod to move upward through the lifting ring. At this time, the connecting rod drives the four lifting belts on both sides thereof to move upward, and lifts the entire device upward through the rotating shell and the side fixing plate. During this process, the guide wheels on both sides of the protective shell can guide the lifting belts to keep the lifting belts stable during the lifting process, thereby ensuring that the entire lifting device remains balanced during the lifting process and reducing the risk of shaking and tilting.
[0019] 7. The present invention provides a buffer assembly. When the connecting rod moves upward, the sling is tightened and presses the guide wheel upward, so that the limiting slide slides upward along the inner wall of the fixed shell, thereby forcing the elastic plate to be deformed under force. During the lifting process, momentary impact force or shaking may occur. The buffer assembly can absorb part of the energy, reduce the impact on the lifting device and the power transformer, and improve the safety and stability of the lifting.

After the position of the fixing device 3 is adjusted to a size suitable for the power transformer, the crane drives the device to move downward as a whole, so that the lateral clamping plate 31 contacts the side wall of the power transformer, and then the telescopic cylinder 12 contracts, and finally drives the displacement adjustment seats 16 on the front and rear sides to approach each other, thereby making the lateral clamping plates 31 approach each other, and clamping and fixing the power transformer; When the power transformer is lifted by the crane and the lifting device, the hydraulic telescopic rod 32 drives the limit slider 33 to slide downward along the inner wall of the lateral clamping plate 31, so that the limit slider 33 drives the bearing assembly 35 to move downward through the sliding rod 34. When the bearing assembly 35 is separated from the side wall of the power transformer, the elastic force of the torsion spring 355 is released, and the limit arc plate 356 is deflected under the limit of the annular fixing plate 354. At this time, the limit arc plate 356 drives the limit rod 358 to slide along the arc hole 350 opened in the wall of the shell 351.

[0025] The arc hole 350 limits the movement of the limit rod 358, thereby limiting the maximum deflection angle of the support block 353.

Regardless of how the size of the transformer changes, the support effect of the support block 353 can be guaranteed to be stable and reliable.
[0026] The lifting device 2 includes a protective shell 21, and guide wheels 25 are rotatably connected to both sides of the protective shell 21. A buffer assembly 26 is fixedly connected to the top of the protective shell 21. A side fixing plate 22 is provided at the bottom of the protective shell 21. A rotating shell 23 is rotatably connected to the outer side of the side fixing plate 22. A sling 24 is fixedly connected to the inner side of the rotating shell 23. A connecting rod 27 is fixedly connected to the top of the sling 24. A lifting ring 28 is fixedly connected to the center of the connecting rod 27. The bottom of the protective shell 21 is fixedly connected to the top of the fixed seat 11, and both sides of the fixed seat 11 are fixedly connected to the outer side of the side fixing plate 22. The outer side of the sling 24 contacts the outer wall of the guide wheel 25. The side fixing plate 22 is located at the bottom of the protective shell 21, and the connecting rod 27 is located at the top of the buffer assembly 26. The outer side of the sling 24 is in contact with the inner side of the buffer assembly 26. When the crane lifts the device as a whole through the lifting device 2, the hook pulls the connecting rod 27 upward through the lifting ring 28. At this time, the connecting rod 27 drives the four slings 24 on both sides thereof to move upward, and lifts the entire device upward through the rotating shell 23 and the side fixing plate 22. During this process, the guide wheels 25 on both sides of the protective shell 21 can guide the sling 24 to keep the sling 24 stable during the lifting process, thereby ensuring that the entire lifting device remains balanced during the lifting process and reducing the risk of shaking and tilting. The gap between the side fixing plate 22 and the fixing seat 11 is conducive to the passage of the rope, so that the user can also use the rope to assist in fixing the power transformer during lifting.
[0027] The buffer assembly 26 includes a fixed shell 261, the inner wall of the fixed shell 261 is slidably connected to a limiting slide 262, the two sides of the bottom of the limiting slide 262 are rotatably connected to guide wheels 263, the top of the limiting slide 262 is fixedly connected to an elastic plate 264, the bottom of the fixed shell 261 is fixedly connected to the top of the protective shell 21, a rectangular hole 265 is opened in the wall of the limiting slide 262, the top of the elastic plate 264 is fixedly connected to the outer side of the fixed shell 261, the outer side of the guide wheel 263 is in contact with the outer side of the sling 24, and the sling 2 The connecting rod 27 passes through the bottom of the guide wheel 263 and the limiting slide plate 262 through the rectangular hole 265. When the connecting rod 27 moves upward, the sling 24 is tightened and presses the guide wheel 263 upward, so that the limiting slide plate 262 slides upward along the inner wall of the fixed shell 261, thereby forcing the elastic plate 264 to deform under force. During the lifting process, there may be instantaneous impact force or shaking. The buffer assembly 26 can absorb part of the energy, reduce the impact on the lifting device and the power transformer, and improve the safety and stability of the lifting.
[0028] Working principle: When in use, the hook of the crane is hung on the lifting ring 28 in the lifting device 2, and then the crane lifts the entire device through the lifting device 2 and places it above the power transformer that needs to be lifted, and then the position of the fixing device 3 is adjusted by the adjusting device 1.
[0029] The fixed seat 11 in the adjustment device 1 serves as a basic support component. The telescopic cylinder 12 can perform telescopic movements. When the telescopic cylinder 12 is extended, it pushes the connecting plate 13 to rise. Under the restriction of the fixed seat 11, the rising connecting plate 13 drives the movable rod 14 to deflect, and the top of the movable rod 14 pushes the cross bars 15 on both sides away from each other. At this time, the displacement adjustment seats 16 at both ends of the cross bars 15 slide along the inner wall of the fixed seat 11. The movement of the displacement adjustment seat 16 drives the fixing device 3 fixedly connected thereto to adjust its position, so as to adapt to power transformers of different sizes.
[0030] After the position of the fixing device 3 is adjusted to a size suitable for the power transformer, the crane drives the device to move downward as a whole, so that the lateral clamping plate 31 contacts the side wall of the power transformer, and then the telescopic cylinder 12 contracts, and finally drives the displacement adjustment seats 16 on the front and rear sides to approach each other, thereby making the lateral clamping plates 31 approach each other, and clamping and fixing the power transformer; When the power transformer is lifted by the crane and the lifting device, the hydraulic telescopic rod 32 drives the limit slider 33 to slide downward along the inner wall of the lateral clamping plate 31, so that the limit slider 33 drives the bearing assembly 35 to move downward through the sliding rod 34. When the bearing assembly 35 is separated from the side wall of the power transformer, the elastic force of the torsion spring 355 is released, and the limit arc plate 356 is deflected under the limit of the annular fixing plate 354. At this time, the limit arc plate 356 drives the limit rod 358 to slide along the arc hole 350 opened in the wall of the shell 351. At the same time, the limit rod 358 drives the support block 353 to deflect along the fixing rod 352 through the assembly plate 357, so that the support block 353 can be automatically popped out from the shell 351; Then the hydraulic telescopic rod 32 contracts, driving the bearing assembly 35 to move upward until the upper surface of the support block 353 contacts the bottom of the power transformer, wherein the arc-shaped hole 350 is provided to limit the movement stroke of the limit rod 358, thereby limiting the maximum deflection angle of the support block 353, so that the support block 353 can stably support the bottom of the power transformer when it pops out; The hydraulic telescopic rod 32 can drive the bearing assembly 35 to move up and down, so that the support block 353 can be adjusted according to the power transformers of different heights. This flexibility allows the hoisting device to adapt to power transformers of various sizes, improving the versatility of the device. By setting the booster wheel 359, after the hoisting is completed, the booster wheel 359 can provide rolling support during the withdrawal process of the support block 353, making the movement of the support block 353 smoother.
[0031] The arc hole 350 limits the movement of the limit rod 358, thereby limiting the maximum deflection angle of the support block 353. This ensures that the support block 353 will not deflect excessively when it pops up, and can support the bottom of the power transformer at a suitable angle. Regardless of how the size of the transformer changes, the support effect of the support block 353 can be guaranteed to be stable and reliable.
[0032] When the crane lifts the entire device through the lifting device 2, the hook pulls the connecting rod 27 upward through the lifting ring 28. At this time, the connecting rod 27 drives the four lifting belts 24 on both sides thereof to move upward, and lifts the entire device upward through the rotating shell 23 and the side fixing plate 22. During this process, the guide wheels 25 on both sides of the protective shell 21 can guide the lifting belts 24 to keep the lifting belts 24 stable during the lifting process, thereby ensuring that the entire lifting device remains balanced during the lifting process and reducing the risk of shaking and tilting. The gap between the side fixing plate 22 and the fixing seat 11 is conducive to the passage of the rope, so that the user can also use the rope to assist in fixing the power transformer during lifting.
[0033] During this process, the sling 24 passes through the bottom of the guide wheel 263 and passes through the limiting slide 262 through the rectangular hole 265. When the connecting rod 27 moves upward, the sling 24 is tightened and squeezes the guide wheel 263 upward, so that the limiting slide 262 slides upward along the inner wall of the fixed shell 261, thereby forcing the elastic plate 264 to deform under force. During the lifting process, momentary impact force or shaking may occur. The buffer component 26 can absorb part of the energy, reduce the impact on the lifting device and the power transformer, and improve the safety and stability of the lifting.
