Electric lifting appliance

Abstract

The invention provides an electric lifting appliance. The electric lifting appliance is provided with a chain and at least one telescopic elastic piece, wherein two opposite ends of each telescopic elastic piece are combined with a first mounting portion and a second mounting portion of the chain separately, a first length is formed between the first mounting portion and the second mounting portion, and a second length generated after the telescopic elastic piece is stretched is smaller than the first length. At least one telescoping elastic piece is provided on the chain of the electric lifting appliance, when the electric lifting appliance is used to lift a steel cord I-shaped wheel to be assembled to an unwinding seat, a reverse acting force applied to the steel cord I-shaped wheel by the telescoping elastic piece upwards lifts the steel cord I-shaped wheel, a gap is formed between the bottom surface of the steel cord I-shaped wheel and the top surface of the unwinding seat, an operator can easily pull a strong magnetic chuck handle to rotate the steel cord I-shaped wheel by one hand, a pin hole is aligned with a hinge pin of the unwinding seat, it is not needed to tension the unwinding force arm to increase the tension of the unwinding seat to avoid rotation of the unwinding seat, and thus the workload and labor intensity of the operator are reduced.

Description

technical field

[0001] The invention relates to an electric sling, in particular to an electric sling applied to a steel cord I-shaped wheel. Background technique

[0002] In the production of steel cord, the weight of the full-wheel steel wire I-shaped wheel produced by the wet drawing machine reaches about 65KG. In order to improve the production efficiency and reduce the labor intensity of the steel cord stranding machine, a rail car is installed next to the stranding machine. The rail car is equipped with an electric spreader to carry the full wheel of steel wire to the pay-off seat of the stranding machine. Carry out the twisting of steel wire.

[0003] When the operator uses the electric spreader on the rail car of the twisting machine tool to lift the full-wheel steel wire I-shaped wheel into the pay-off seat, it is necessary to align the pin hole of the full-wheel steel wire I-shaped wheel with the pin shaft on the pay-off seat. Through the rotation of the pay-off ...
