Abstract

The invention relates to a multi-arm lifting appliance. The multi-arm lifting appliance comprises a lifting beam, movable lifting arms, Y-shaped load-bearing lifting arms, lifting feet and lifting beam cantilevers, wherein the lifting beam is provided with a circular sliding rail and gears; the number of the lifting beam cantilevers is three or above, and the lifting beam cantilevers are respectively and fixedly connected with the lifting beam in parallel through the gears, and are uniformly arranged in the circumference direction; each lifting beam cantilever is provided with a sliding mechanism and connected with the corresponding movable lifting arm through the sliding mechanism; each movable lifting arm is provided with a telescopic mechanism, is adjustable in length, and can slide inside and outside along the corresponding lifting beam cantilever; the lower end of each movable lifting arm is provided with a connecting hole through which a connecting pin passes, and the lower end of each movable lifting arm is connected with the linear end of the corresponding load-bearing lifting arm through the corresponding connecting pin; and the lifting feet are fixedly arranged at the lower forked parts of the load-bearing lifting arms respectively. The multi-arm lifting appliance can conveniently, safely and reliably lift a coil or a coil group, and the lifting arms can be quickly dismounted to be mounted on other lifting tools for use. The multi-arm lifting appliance is simple in structure, advanced in technology, and convenient to install and has wide popularization and application prospects.

Description

technical field [0001] The invention belongs to the technical field of transformer manufacturing, and in particular relates to a dobby sling and a hoisting method thereof, which are used for suiting coils or coil groups of converter transformers and AC transformers. Background technique [0002] In the production and manufacturing process of power transformers, the assembly of transformer coils is an important production link. In this link, it is usually necessary to use professional lifting tools and other tooling to lift the coil or coil group. [0003] The lower part of the body insulation of converter transformers, AC transformers and other products is an oil guide box structure, and the structure is fixed after the insulation parts around the coil outlet are installed. The current spreader interferes seriously with the coil head during the hoisting process, and it is easy to damage the coil head or the paper tube during lifting; at the same time, the spreader interferes...
