Conductive control device of fiber brush structure

Abstract

The invention discloses a conductive control device of a fiber brush structure, and the device comprises a central slip ring assembly (2), a base (4), a transmission disc (5), a supporting disc (6) and a transmission pin shaft (7). A circular boss is arranged at the middle of the base (4), and a matching hole is formed at the middle of the circular boss. The central slip ring assembly (2) is fixedon the supporting disc (6), and the bottom end of the supporting disc (6) is fixed on the transmission disc (5) through a matching hole at the middle of the base (4). The transmission pin shaft (7) in threaded connection is further arranged below the transmission disc (5). The device is characterized in that the electric conduction control device further comprises a fiber brush assembly (3); thefiber brush assembly (3) is fixed to the circular boss of the base (4) through a bolt, and the transmission pin shaft (7) transmits power on a later-stage connecting device to the transmission disc (5) to drive the center sliding ring assembly (2) to rotate together, so that the center sliding ring assembly (2) and the fiber brush assembly (3) move relatively. The device is convenient to use.

Description

technical field [0001] The invention relates to engineering hoisting machinery and drilling machinery, in particular to a conductive control device with a fiber brush structure. Background technique [0002] The conductive control device is used for signal transmission of large-scale mechanical equipment such as heavy machinery and equipment. The single copper wire brush commonly used inside the existing various types of conductive control devices has a gap between the single copper wire of the copper wire brush and the conductive ring. At the contact point, under the condition of surrounding, the contact pressure is large, the contact wear is large, and the service life is short; in addition, the single copper wire will wear out after a long time of use, and the copper wire will loosen, resulting in poor contact. Contents of the invention [0003] In view of the above shortcomings, the purpose of the present invention is to provide a conductive control device with a fiber...
