Flame proof cable winding drum

Abstract

The invention relates to a cable winding device, in particular to an explosion-proof cable drum, which solves the problem of burning out of slip rings due to arcing caused by the fact that a brush is easy to wear and generate gaps or a brush clamping device is aged and loosened along with time in a collecting slip ring of the prior cable drum. The explosion-proof cable drum is provided with a drum shell and the collecting slip ring, wherein the collecting slip ring is provided with two relatively rotational slip rings, and one is a static slip ring and the other is a movable slip ring; and the static slip ring is in end face contact with the movable slip ring. The explosion-proof cable drum can safely convert rotary current into static current. The explosion-proof cable drum is taken as a changeover gear of main voltage source input, safely converts the rotary current which is inputted by the exterior of the drum into the relatively static current through relative rotation of the movable slip ring and the static slip ring, and leads the static current into an electric cabinet to supply power to the whole machine. The explosion-proof cable drum adopts a novel slip ring group, guarantees enough contact area and compression strength, and better transfers current.

Description

technical field [0001] The invention relates to a cable winding device, in particular to a flameproof cable reel. Background technique [0002] At present, the general cable reel converts the external rotating current into a static current through the current collector slip ring to supply power to the equipment, and the current general current collector slip ring is in the form of a slip ring and a brush, and the brush and the slip ring The ring is in two-point or three-point contact, and the brush is easy to wear to produce a gap or the clamping device of the brush is aged and loosened over time, which will cause arcing and burn out the slip ring. Contents of the invention [0003] The purpose of the present invention is to provide a flameproof cable reel, which solves the problem that in the current collector slip ring of the existing cable reel, the brushes are easy to wear and produce gaps or the brush clamping device ages and loosens over time, which leads to arcing a...
