Adjustable power cable hoisting device

Abstract

The invention provides an adjustable power cable hoisting device. Side plates are vertically arranged on the left side and the right side of a bottom plate, hoisting rings are arranged on the side plates, a front roll shaft and a rear roll shaft are erected between the left side plate and the right side plate, a sliding rail is arranged on the bottom plate between the front roll shaft and the rear roll shaft, and two telescopic columns spaced left and right are vertically arranged in the middle of the sliding rail; the tops of the two telescopic columns are connected with supporting plates, a lower roll shaft which extends left and right and can axially rotate is erected between the two supporting plates, and the two supporting plates are connected with two connecting rod line pressing assemblies which are symmetrical left and right. The electric wire is clamped through the gravity of the electric wire, shaking of the electric wire is relieved, the stress area of the electric wire is large and stress is uniform when the electric wire is lifted, the electric wire is lifted by the roll shaft in the front-back direction, large-angle bending of the electric wire is avoided, the roll shaft rotates when the electric wire is pulled, pulling resistance is reduced, and working efficiency and safety are improved.

Description

technical field [0001] The invention relates to an adjustable power cable hoisting device. Background technique [0002] At present, in the power construction process of wire poles, it is necessary to use a crane to lift the wires, then pull the wires on the wire poles, and finally complete the fixing of the wires. Now the cranes generally use hooks to directly hook the wires, but the weight of the wires Larger, and the hook is thinner, so the pressure on the wire is relatively large, which is easy to cause damage to the wire, and the hook shakes relatively large, it is not easy to control the vertical lifting of the wire, and the resistance encountered when pulling the wire is relatively large, so construction The efficiency is relatively low and the security is not high. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides an adjustable power cable hoisting device, which is not easy to damage the wires and...
