A marine collector ring assembly

Abstract

The invention discloses a collector ring assembly for a ship. The collector ring assembly comprises a power supply box, a power output device and a signal output device, wherein the power output device comprises an iron disk, a lower end cover arranged above the iron disk, a connecting plate which is fixedly connected with the lower end cover by means of a first insulating tube, and a power output assembly; the power output assembly comprises copper slip rings and a slip ring fixing plate; the copper slip rings are vertically arranged between the slip ring fixing plate and the connecting plate by means of the first insulating tube; a copper brush yoke is fixedly arranged on the first insulating tube and is connected with the copper slip rings through leads; a carbon brush is fixedly arranged on the copper brush yoke; the signal output device comprises a steel roller, an upper end cover and a signal output assembly; the signal output assembly is a conducting slip ring; an upper shaft head of the conducting slip ring is connected with the upper end cover through a precision bearing; and a lower shaft head of the conducting slip ring is rotationally connected with the slip ring fixing plate. The collector ring assembly disclosed by the invention has the advantages of simpler structure, small size, remarkably-prolonged service life and convenience for using and mounting.

Description

technical field [0001] The invention relates to a marine collector ring assembly, which plays the role of power output and signal transmission. Background technique [0002] Slip rings are widely used in cranes, which are electrical contact sliding connection devices, and play the role of power output and signal transmission. The original marine collector ring signal device has no sealing device, and its structure includes slip rings, brush holders, extension springs, carbon brushes and other components. The structure is complex, the components are scattered, not integrated and the components are small in size. Due to the humidity at sea and the high salt content in the air, it is easy to cause corrosion and rust to internal parts, and make components such as brush holder extension springs useless. Frequent replacement and maintenance of components are required, which affects the normal operation of the equipment. Moreover, the brush holder in the collector ring power outpu...

Problems solved by technology

The original marine collector ring signal device has no sealing device, and its structure includes: slip rings, brush holders, tension springs, carbon brushes and other components. The structure is complex, the components are scattered, not integrated and the components are small in size

Due to the humidity at sea and the high salt content in the air, it is easy to cause corrosion and rust to internal parts, and make the brush holder tension spring and other components useless. Frequent replacement and maintenance of components are required, which affects the normal operation of the equipment.

In addition, the brush holder in the power output device of the collector ring is a DMC brush holder, which is easy to be damaged. Since the strength of DMC cannot be reached, it is easy to break the brush holder when replacing the carbon brush and maintaining the equipment.
