External slip ring box of shore power cable winch

Abstract

The invention discloses an external slip ring box of a shore power cable winch. The external slip ring box comprises a box body, a door 1, a door 2, slip rings, a slip ring connector, a slip ring hold sleeve, insulators and electric brushes. An electric brush support beam is arranged in the box body. The slip ring hold sleeve is installed on the electric brush support beam so as to support the slip rings. The insulators are also installed on the electric brush support beam. The insulators are provided with electric brush clamping seats. The electric brushes are installed in the electric brush clamping seats so as to support the slip rings. Through holes are respectively formed in the side surface and the bottom part of the box body so as to facilitate wiring. The external slip ring box of the shore power cable winch has the advantages that the external slip ring box has an independent box body structure and no longer needs to be installed in the cable winch, so that the maintenance and the replacing of the electric brushes are convenient, and the installation and the wiring are facilitated; in addition, a heater is added, the slip ring box is prevented against condensation, and the normal work of the slip ring box is ensured.

Description

technical field [0001] The invention relates to a slip ring box for a shore power cable winch, which belongs to the field of power transmission equipment. Background technique [0002] Shore power supply is a high-power variable frequency power supply equipment specially designed and manufactured for harsh environments such as high temperature, high humidity, high corrosion, and heavy load impact on ships and shore terminals. When it is working, in order to facilitate access, use and storage, a shore power cable winch will be used. Since the cable winch requires unlimited continuous rotation and needs to transmit power from a fixed position to a rotating position, a conductive slip ring is required to realize the power transmission of two relative rotating mechanisms. [0003] In the existing shore power cable winches, the slip ring device is installed inside the winch, which can save space and materials. However, slip ring brushes are vulnerable and consumable parts and n...

AI Technical Summary

Problems solved by technology

However, slip ring brushes are vulnerable and consumable parts and need to be replaced regularly. At the same time, slip rings require high installation accuracy and are difficult to install

Therefore, the slip ring installation method of this structure cannot meet the requirements of convenient maintenance and replacement of parts, and the installation is difficult

Moreover, the inner space of the winch is relatively closed. During long-term use, condensation will form inside the winch, and even water will accumulate at the bottom, which cannot be ruled out.
