Storage frame suspension sling cable

Abstract

The invention relates to a storage frame suspension lifting appliance cable. The cable comprises a fiber braided reinforcing layer and an outer sheath layer which are concentrically arranged in sequence from inside to outside. A bearing unit concentric with the fiber woven reinforcing layer is arranged in the fiber woven reinforcing layer; the bearing unit is arranged in the center of the cable; aplurality of reinforcing cores are arranged between the bearing unit and the fiber woven reinforcing layer; a plurality of conductive conductors are arranged outside each reinforcing core; an insulating layer is extruded outside each conductive conductor to form an insulating wire core unit. The insulating wire core units are annularly distributed outside the reinforcing core; the insulating wirecore units and the reinforcing cores are stranded to form a cable core; a wrapping layer is arranged outside each cable core, the wrapping layers are annularly distributed outside the bearing unit, and the space between every two adjacent wrapping layers and the fiber woven reinforcing layer is filled with a balance weight lead core. The cable has good flexibility and dynamic balance, and the problems that the cable is distorted and deformed, swings in the air, falls into a frame and deviates, a signal unit is prone to breakage, and the cable bulges and is not resistant to bending are solved.

Description

technical field [0001] The invention belongs to the technical field of electric cables, in particular to a storage frame suspension suspender cable. Background technique [0002] Cranes, port machinery, and high-altitude up and down mobile equipment need to perform multiple high-altitude up and down movements every day. The suspension spreader cable plays an important role in signal transmission and power supply during use, but the existing suspension cable Due to its up and down reciprocating motion, the phenomenon of twisting and deformation of the cable, disconnection of the signal unit, and bulging of the cable may occur from time to time, and the twisting and deformation of the cable will cause the cable to swing in the air, and the storage frame will deviate when it lands. There are potential safety hazards in the aspect, therefore, there are shortcoming and weak point in the prior art. Contents of the invention [0003] The object of the present invention is to pro...
