[0021] Embodiment 1

[0022] Combined with Figures 1 - 3 , a lifting device for installing a power transformer includes a lifting assembly 2 provided at the top of the power transformer body 1. The lifting assembly 2 has two lifting plates 3 and adjusting screws 11.

[0023] Referring to Figure 2 and Figure 3 , the two lifting plates 3 are installed at both sides of the top surface of the power transformer body 1. The two adjusting screws 11 penetrate through the front - and - rear ends of both sides of the lifting plates 3, and the adjusting screws 11 are slidably connected to the lifting plates 3. Suspension buckles 10 are fixedly connected to the front - and - rear ends of the top surface of the lifting plates 3. The lifting plates 3 are connected to a hook 9 through the suspension buckles 10 with a suspension rope 8. One end of the suspension rope 8 away from the hook 9 is connected to a lifting block. Locknuts 12 are threadedly connected to the outer circumference of the adjusting screws 11 and on both sides of each lifting plate 3, and the inner sides of the locknuts 12 are in contact with the outer sides of the lifting plates 3. Handles are fixedly connected to the front - and - rear ends of the top of the lifting plates 3, and the lifting plates 3 are provided with anti - slip patterns.

[0024] Specifically, by hanging the suspension rope 8 on the suspension buckles 10 of multiple lifting plates 3, multiple stress points can be provided for the power transformer body 1, so as to improve the lifting stability and reduce the shaking to a certain extent. During lifting, personnel can hold the handles provided on the top surface of the lifting plates 3, which is convenient for personnel to pull and adjust the position. And by screwing the locknuts 12 provided on both sides of the lifting plates 3, it is convenient to adjust the position of the lifting plates 3, thereby changing the position of the suspension buckles 10 and improving the applicability.

[0025] Embodiment 2

[0026] Referring to Figure 2On the basis of the first embodiment, the bottom end of the hanging plate 3 is fixedly connected with a fixing screw 4 near the front and rear ends, and the outer ring of the fixing screw 4 is slidably installed with a support block 1 5 and a support block 2 6, the top surface of the support block 1 5 is in contact with the upper bottom surface of the power transformer body 1, and the bottom surface of the support block 2 6 is in contact with the bottom surface of the power transformer body 1, and the outer ring of the fixing screw 4 and the bottom ends of the support block 1 5 and the support block 2 6 are threadedly connected with an anti-slip bolt 7, the top end of the anti-slip bolt 7 is in contact with the bottom ends of the support block 1 5 and the support block 2 6, and the bottom end of the power transformer body 1 is fixedly connected with a mounting block near the front and rear ends, and the bottom end of the fixing screw 4 does not exceed the bottom end of the mounting block.

[0027] Specifically, by setting the support block 1 5 and the support block 2 6 to be fixed on the side of the power transformer body 1, it is convenient to perform secondary fixation on the power transformer body 1, thereby reducing the probability of the power transformer body 1 falling, and each component does not need to pass through the bottom of the power transformer body 1 for support, thereby avoiding a large impact on the installation operation. At the same time, after hoisting, the clamping of the support block 1 5 and the support block 2 6 can be released by screwing the anti-drop bolt 7 downward, and then the hoisting plate 3 can be pulled out from the side.

[0028] During actual operation, before lifting, the lifting blocks connected to the top ends of the multiple lifting ropes 8 can be connected to the external lifting equipment, and then the lifting ropes 8 can be hung on the hanging buckles 10 of multiple lifting plates 3 through the hooks 9, so that the power transformer body 1 can have multiple force points to improve the lifting stability and reduce a certain degree of shaking. During lifting, personnel can hold the handles set on the top surface of the lifting plate 3 to adjust it, which is convenient for personnel to pull and adjust the position. By turning the anti-loosening nuts 12 set on both sides of the lifting plate 3 in turn, the position of the lifting plate 3 at the power transformer body 1 can be adjusted. Without interfering with the installation and fixation, the position of the hanging buckle 10 can be adjusted to facilitate improving applicability.

[0029] By setting the support block 1 5 and the support block 2 6 to be fixed on the side of the power transformer body 1, it is convenient to perform secondary fixation on the power transformer body 1, reducing the probability of the power transformer body 1 falling, and each component does not need to pass through the bottom of the power transformer body 1 for support, which can avoid a major impact on the installation operation.

[0030] At the same time, after hoisting, the clamping of support block 1 5 and support block 2 6 can be released by screwing down the anti-drop bolt 7, and then the hoisting plate 3 can be pulled out from the side without lifting it back and forth or performing multiple steps to remove the hoisting equipment, thereby improving the hoisting efficiency.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
