Technical Field
[0001] This utility model relates to the field of transformer assembly technology, specifically to a hoisting fixture for assembling an amorphous alloy dry-type transformer. Background Technology
[0002] Amorphous alloy dry-type transformers are power transformers that use amorphous alloy materials as their core and employ a dry-type insulation structure. This type of transformer combines the high efficiency and energy-saving characteristics of amorphous alloy materials with the environmental protection and fire resistance advantages of dry-type transformers. Assembly is a crucial step in the manufacturing process of amorphous alloy dry-type transformers, directly affecting their electrical performance, mechanical stability, and long-term operational reliability.
[0003] During the assembly of amorphous alloy dry-type transformers, the coils need to be fitted onto the iron core.

This method suffers from poor stability, easily causing the components to tilt during hoisting, which can easily lead to damage if not handled carefully. Therefore, this invention proposes a hoisting fixture for assembling amorphous alloy dry-type transformers to improve the stability of the assembly and hoisting process. Utility Model Content

The lifting cylinder 1 is a horizontally arranged cylindrical structure. A lifting lug 2 is provided on the upper part of the lifting cylinder 1 for connecting hoisting equipment. A slot 11 is provided through the lower part of the lifting cylinder 1. The rotating rod 4 is located inside the lifting cylinder 1, and its two ends are vertically and rotatably connected to the two ends of the lifting cylinder 1. The two ends of the rotating rod 4 are respectively provided with a first thread 41 and a second thread 42 with opposite directions of rotation. The lifting frame 5 includes a sliding sleeve 51, a first vertical rod 52, a frame body, and a support block 57. There are two lifting frames 5, and the two lifting frames 5 are opposite to each other; the sliding sleeve 51 of one lifting frame 5 is threaded to the first thread 41, and the sliding sleeve 51 of the other lifting frame 5 is threaded to the second thread 42; one end of the first vertical rod 52 is connected to the sliding sleeve 51, and the other end passes through the slot 11 and is connected to the frame body; the two opposing lifting frames 5 can move closer or further away from each other along the slot 11 under the rotation drive of the rotating rod 4; the frame body is used to abut against the side wall of the receiving hoisting part; the lower part of the frame body is provided with the support block 57, and the support block 57 is used to support the bottom of the part to be hoisted.
[0030] In the technical solution of this utility model, both ends of the rotating rod 4 are rotatably connected to both ends of the lifting cylinder 1. The first thread 41 and the second thread 42 have opposite directions of rotation. One of the lifting frames 5 is threaded to the first thread 41, and the other lifting frame 5 is connected to the second thread 42. Therefore, when the rotating rod 4 rotates, the two opposing lifting frames 5 can move closer or further away from each other.

After hoisting is completed, by driving the rotating rod 4 to rotate in the opposite direction, the two lifting frames 5 can be driven to move further away from each other, thereby releasing the hoist. In summary, the hoisting fixture for assembling amorphous alloy dry-type transformers proposed in this utility model has a simple structure and is easy to operate.

[0041] Preferably, the slot 11 is rectangular, and the sidewall of the slot 11 abuts against the outer sidewall of the first vertical rod 52.
[0042] Specifically, the first vertical rod 11 can move along the length direction of the slot 11, and the side wall of the slot 11 abuts against the outer side wall of the first vertical rod 52 to prevent the lifting frame 5 from rotating when the rotating rod 4 rotates, which helps to ensure the stability of the lifting frame 5's movement.
[0043] Preferably, the frame includes a first horizontal bar 54 and a second horizontal bar 56 that are parallel to each other, and a second vertical bar 55 that is perpendicularly connected to the first horizontal bar 54 and the second horizontal bar 56 at both ends; one end of the first vertical bar 52 is connected to the middle of the first horizontal bar 54; there are two second vertical bars 55, which are symmetrically distributed on both sides of the first vertical bar 52.
[0044] The frame provides sufficient support for the side walls of the component to be lifted, thereby improving lifting stability. Specifically, the contact surfaces of the first horizontal bar 54, the second horizontal bar 56, and the second vertical bar 55 with the component to be lifted can be flat or curved to adapt to different surface shapes of the component, increasing the contact area and thus improving lifting stability.

The support block 57 can be rotated to be perpendicular to the second crossbar 56 to support the bottom of the part to be lifted. The support block 57 can also be rotated into the mounting slot so that the support block 57 does not exceed the second crossbar 57, so that the support block 57 can leave the bottom of the part to be lifted in a narrow space.
[0048] Preferably, a first anti-slip pad 6 is provided on the side of the frame that is in contact with the part to be hoisted; a second anti-slip pad 7 is provided on the side of the support block 57 that is in contact with the part to be hoisted.
[0049] The anti-slip mat increases the friction between the lifting frame 5 and the object to be lifted, thus improving lifting stability. Specifically, both the first anti-slip mat 6 and the second anti-slip mat 7 are rubber mats.
[0050] Preferably, the lifting frame 5 further includes diagonal braces 53; one end of the diagonal brace 53 is connected to the first vertical rod 52, and the other end of the diagonal brace 53 is connected to the first horizontal rod 54; there are two diagonal braces 53, which are symmetrically arranged on both sides of the first vertical rod 52.
