[0002] Transformers are mainly composed of an iron core and a housing. They are relatively heavy and are core equipment in the power system.

Second, transformers operating for extended periods are prone to aging or malfunctions, also necessitating specialized hoisting equipment for lifting and repairing the transformer or its core. Both transformer installation and repair involve complex processes, high operational difficulty, and consequently, high costs. Therefore, a transformer hoisting fixture is proposed.

[0008] Furthermore, there are two utility poles, which are arranged symmetrically at intervals. There are also two upper channel steels and two lower channel steels. The two upper channel steels are fixedly installed on the same side of the two utility poles and at the same height. The two lower channel steels are also fixedly installed on the same side of the two utility poles and at the same height.

[0009] Furthermore, a lifting cross brace is fixedly installed between the two upper channel steels, a through slot is opened in the middle of the lifting cross brace, a lifting shaft is fixedly installed in the middle of the lifting cross brace, and a hoist is installed on the lifting shaft.

[0031] Specifically, bolt mounting holes are provided at the top middle position of the upper channel steel 2 and at both ends of the lifting cross brace 6. The two ends of the lifting cross brace 6 are fixedly installed on the two upper channel steels 2 by bolt assemblies. The lifting shaft 602 is located in the middle position of the lifting channel steel and is used to install the hoist 603. The through slot 601 is opened on the lifting cross brace 6 at the bottom of the lifting shaft 602. The hook at the upper end of the hoist 603 passes through the through slot 601 and is installed on the lifting shaft 602. The lower end of the hoist 603 has a hook for lifting the transformer 5.

[0033] As a preferred option, it remains as follows Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, there are two supporting channel steels 4, located on both sides of the utility pole 1, and a tie rod 401 is fixedly installed between the two supporting channel steels 4. Specifically, the two supporting channel steels 4 are installed on both sides of the two utility poles 1, and each utility pole 1 has two tie rods 401 on both sides, which fix the two supporting channel steels 4 to the utility pole 1.

[0034] Working principle: Transformer 5 is typically installed outdoors between two utility poles 1. First, two workers climb the two utility poles 1 respectively, installing the upper channel steel 2 and lower channel steel 3 at the designated height. The two upper channel steel 2 and two lower channel steel 3 are fixed to the utility poles 1 using U-shaped clamps 7 and bolt assemblies. Then, the two ends of the lifting cross brace 6 are fixed between the two upper channel steel 2 using bolt assemblies. The upper hook on the hoist 603 is suspended from the lifting shaft 602 of the lifting cross brace 6. The lower hook on the hoist 603 is extended downwards to the ground under manual operation. At this time, the lifting wire rope is installed on the lifting ring at the top of the transformer 5 on the ground. The middle part of the wire rope is a wire rope sling. The wire rope sling is attached to the lower hook of the hoist 603. Then, one of the installation workers manually... Pull the hand chain of the hoist 603 at a constant clockwise speed to raise the transformer 5 to a suitable height. At this time, the height of the bottom support leg 501 of the transformer 5 is higher than the height of the lower channel steel 3. Then, another worker places two support channel steels 4 on the lower channel steel 3, adjusts the position of the two support channel steels, and fixes the support channel steel 4 on this worker's side to the lower channel steel 3 with bolt assembly. At the same time, fix the two support channel steels 4 on this worker's side to the utility pole 1 with pull rod 401. Then, manually pull the hand chain counterclockwise at a constant speed to lower the support leg 501 of the transformer 5 onto the support channel steel 4. At this time, the worker releases the hand chain and fixes the other end of the support channel steel 4 to the lower channel steel 3 and the utility pole 1 respectively with bolt assembly and pull rod 401. Then, fix the bottom support leg 501 of the transformer 5 to the support channel steel 4 with bolt assembly.

[0035] Bolt mounting holes are provided at both ends of the bottom of the upper channel steel 2. After the transformer 5 and the supporting channel steel 4 are installed, the hoist 603 and the lifting cross brace 6 are removed. At this time, two workers loosen the U-shaped clamp 7 of the upper channel steel 2, move the upper channel steel 2 down to the top of the supporting channel steel 4, fix the upper channel steel 2 to the supporting channel steel 4 with bolt assembly, and then fix the upper channel steel 2 to the utility pole 1 with the U-shaped clamp 7 to enhance the fixing strength of the supporting channel steel 4.

[0036] When transformer 5 is in operation for a long time, it is necessary to carry out regular inspection and maintenance. If it is necessary to lift the core of transformer 5 for inspection and maintenance, the above installation process can be followed. Simply loosen the U-shaped clamps 7 of the two upper channel steels 2, move the two upper channel steels 2 upward to a suitable height, and install the lifting cross brace 6 and hoist 603 between the two upper channel steels 2. The core of transformer 5 can then be lifted for inspection and maintenance. The inspection and lifting is simple, easy to operate, and saves costs.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
