Abstract

The invention relates to the technical field of cable winding, and provides a cable extension and retraction device used for direct-current power supply. The cable extension and retraction device comprises a supporting frame, wherein a roller frame is fixedly arranged on the supporting frame; a plurality of rollers are arranged on the roller frame; an arc-shaped frame is arranged above the rollerframe; the bottom surface of the arc-shaped frame abuts against the rollers; two support boxes are fixedly arranged on the arc-shaped frame, and an included angle between the two support boxes is notsmaller than 60 degrees; a plurality of lift columns are arranged on the support boxes; and support rollers are arranged on the lift columns. The two support boxes with certain included angle are fixedly arranged on the arc-shaped frame, so that a wire coil of a winding assembly rotates on the support rollers of the support boxes, and gravity of the wire coil is shared by the support boxes, and therefore, extra load borne on a winding shaft is avoided. Cable extension and retraction work is smoother and more stable, quality and efficiency of extension and retraction operation is effectively guaranteed. Meanwhile, the arc-shaped frame can rotate relative to the roller frame, and can rotate by a corresponding angle under action of gravity while an operation site has gradient, so that a vertical state is kept, and toppling risk is avoided.

Description

technical field [0001] The invention belongs to the technical field of cable winding, and in particular relates to a cable retracting device for DC power supply. Background technique [0002] At the installation and construction site of the cable, the wire reel is usually erected on site so that it can be rotated to realize the retraction and release of the cable. [0003] At present, the current erection method is mainly to set up the central axis of the wire reel, and realize the retraction and release of the cable through the rotation of the wire reel; And the weight of spool is bigger, and the frictional force that axis rotates is bigger, and rotation is not smooth, and the burden of spool is bigger. [0004] Most of the construction sites are in the wild, and the situation is more complicated. In the existing erection method, the center of gravity is relatively high. If the construction is carried out on some slopes, the risk of toppling will be greater and the diffic...
