Power wire winding and unwinding device with adjustable inner diameter

Abstract

The invention provides a power wire winding and unwinding device with the adjustable inner diameter, and relates to the technical field of power equipment. The power wire winding and unwinding devicewith the adjustable inner diameter comprises a support, wire blocking plates, a spindle, adjusting rods and a telescopic assembly, the two wire blocking plates are arranged and are fixedly connected with the spindle, the spindle is in pivot joint with the support, multiple first sliding grooves are circumferentially formed in the wire blocking plates in a manner of surrounding the rotating center,the length direction of the first sliding grooves faces the rotating center of the wire blocking plate, the first sliding grooves in the two wire blocking plates are in one-to-one correspondence, andthe two ends of the adjusting rods are in sliding fit with two first sliding grooves, in one to one correspondence, on the two wire blocking plates; the telescopic assembly is in drive connection with the adjusting rods, and enables all the adjusting rods to slide along the corresponding first sliding grooves at the same time. The technical problems that in the prior art, manual wire winding andunwinding waste time and labor, efficiency is low, injuries are easily caused, other potential safety hazards are caused, wire bundles formed through winding wires with different wire diameters are scattered and inconsistent, and the transport is affected are solved.

Description

Technical field [0001] The present invention relates to the technical field of power equipment, in particular to a retractable device for power wires with adjustable inner diameters. Background technique [0002] At present, low-voltage wires commonly used in the power industry are divided into 240mm according to their wire diameter 2 -95mm 2 For other models, the power wires are factory-packaged in a 100-meter-a-bundle ring-shaped standard package, and their weight ranges from about 107kg to 25kg. Low-voltage wires need to be laid out during power repairs and engineering construction. Operators need to hold the low-voltage wires while walking and laying out the wires. The wires are scattered and disorderly, and the manual laying-off efficiency is low. At the same time, due to the heavy weight of the bundles of wires, the workers sometimes slip and fall during transportation. . [0003] Similarly, the broken wires after emergency repairs or engineering transformations are also col...
