Abstract

The invention discloses a lifting appliance for a reeled cable. The lifting appliance comprises a core shaft and a sleeve which is movably sleeved on the core shaft in a guide manner; expansion sheets are articulated on the sleeve; a press joint is fixedly arranged at one end (which is near an articulated shaft) of each expansion sheet; each press joint is provided with an arc press surface; an upper ejector pressure head and a lower ejector pressure head are oppositely arranged on the core shaft up and down; a first elastic piece applying upward acting force to the lower ejector pressure head is arranged between the core shaft and the lower ejector pressure head; the lower ejector pressure head is provided with a lower ejector pressure surface in rotary friction fit with the arc press surface when the sleeve moves downwards relatively to the core shaft; the upper ejector pressure head is provided with an upper ejector pressure surface in the rotary friction fit with the press surface when the sleeve moves upwards relatively to the core shaft; and a second elastic piece applying upward acting force to the sleeve and / or downward acting force to the core shaft is arranged between the core shaft and the sleeve. With the adoption of the lifting appliance provided by the invention, the operation after lifting can be eliminated; the labor intensity of workers can be reduced; and the lifting efficiency can be improved.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hoisting tool for a coiled cable. Background technique [0002] With the continuous development of the varieties and specifications of cables, the weight of a set of cables has increased from more than ten kilograms to more than forty kilograms. If the method of manual boxing is still used, the labor intensity of workers will become very high. Lifting is particularly important. However, most of the existing spreaders need manual operation to assemble and disassemble the spreader and the cable core during use. However, due to the limitation of the production workshop space, the boxes need to be stacked. , manual operation removes the spreader from the cable core, which undoubtedly increases the labor intensity of the workers, and in addition to the height of the stack, the operation is inconvenient and the lifting efficiency is also low. Contents of the invention [0003] The purpose of ...
