Low-voltage cable reel with embedded slip ring

Abstract

The invention discloses a low-voltage cable reel with an embedded slip ring. The low-voltage cable reel comprises a base, a cable winding bucket, a slip ring device and a reel driving device, wherein the slip ring device is arranged in the cable winding bucket, and comprises a slip ring mechanism and an electric brush mechanism; the slip ring mechanism comprises a slip ring group consisting of a plurality of slip rings, a bearing disk, a plurality of fixing bolts and a fixed plate; the plurality of fixing bolts are used for fixedly connecting the slip ring group with the bearing disk; the fixed plate is fixed on the inner wall of the cable winding bucket; one end of the slip ring device is supported on the middle part of the fixed plate, and the other end of the slip ring device is supported at the inner end of a main shaft; the electric brush mechanism comprises an insulating bracket, a plurality of electric brush spring groups, a plurality of electric brushes and a plurality of flexible current conveying belts; the insulating bracket is fixed on the inner wall of the cable winding bucket; and the plurality of electric brushes are contacted with corresponding slip rings respectively. According to the low-voltage cable reel, the slip ring device is arranged in the cable winding bucket, so that the low-voltage cable reel is simple and reasonable in structure, is easy and convenient to operate, and is safe and reliable; and the other side of the cable winding bucket is provided with an access cover, and the inside of the cable winding bucket can be overhauled or replaced by opening the access cover only, so that high working efficiency is achieved.

Description

technical field [0001] The invention relates to a cable reel, in particular to a low-voltage cable reel with a built-in slip ring, and belongs to the technical field of cable retracting and unwinding equipment. Background technique [0002] At present, the known low-voltage cable reels are divided into two types: end face slip ring type and external radial slip ring type. The radial slip ring reel has potential safety hazards because the cable at the inlet port is not directly connected to the slip ring, and the slip ring device is located on the end face of the cable winding barrel, which increases the volume of the reel. The structure of the slip ring assembly of the above two reeling cars is unreasonable and poor in watertightness. At the same time, when replacing or overhauling the inside of the cable drum, all the cables wound on the cable drum must be removed, which is a heavy and cumbersome workload.

[0002] At present, the known low-voltage cable reels are divided into two types: end face slip ring type and external radial slip ring type. The radial slip ring type reel has potential safety hazards because the cable at the inlet port is not directly connected to the slip ring, and the slip ring device is located at the end of the cable winding barrel, which increases the volume of the reel

The structure of the slip ring assembly of the above two reeling cars is unreasonable, and the watertightness is poor. At the same time, when the inner part of the cable drum is replaced or repaired, all the cables wound on the cable drum must be removed, and the workload is heavy and cumbersome.
