Description

Technical Field

[0001] The utility model relates to the technical field of transformer processing, in particular to transformer core hoisting equipment. Background Art

[0002] The transformer's core forms the transformer's magnetic circuit and also serves as the body's skeleton. Transformer cores are typically constructed from laminated silicon steel sheets coated with insulating varnish. The purpose of coating the core with insulating varnish is to reduce core losses. Without varnish, the core acts like a large conductor with low resistance and high induced current, generating significant eddy current losses. Therefore, while the core is being coated with insulating varnish, it can be hoisted using transformer core hoisting equipment.

[0003] Chinese Patent No. 202420581181.0 provides a transformer core hoisting device, which includes a base plate, a crossbeam, a winding mechanism, and a sliding mechanism.

The sliding mechanism is fixedly installed on the base plate, and the core is placed on the sliding mechanism. The transformer core hoisting device described in the utility model ensures that the core does not fall over after being lifted through the coordinated arrangement of the base plate and the bracket, ensures that the core can be lifted through the coordinated arrangement of the crossbeam and the winding mechanism, ensures that the core can be turned over through the arrangement of the sliding mechanism, ensures that the height of the crossbeam can be adjusted through the arrangement of the hydraulic cylinder to facilitate the turning of the core, and ensures that the core can be automatically turned over through the arrangement of the two sets of winding mechanisms, thereby reducing manual operation.

[0004] However, the spacing between the pulleys on both sides of the above-mentioned lifting equipment is designed to be fixed and non-adjustable. When faced with transformer cores of different sizes, weights or specific lifting requirements, it is difficult to adapt to various usage scenarios. The size and weight differences may be very large. The fixed pulley spacing is often difficult to meet all lifting requirements, which may lead to low lifting efficiency. Therefore, a transformer core lifting equipment is proposed to solve the above problems. Utility Model Content
