A hydraulic-electric hybrid slip ring device

Abstract

Provided is a liquid, power and gas mixed slip ring device. A conductive heave-current part of a rotor is internally provided with multiple heavy-current conductive copper rings, when power and heavycurrent are provided, the heavy-current conductive copper rings make contact with a heavy-current support tube to make transmission, and a heat radiation structure of the conductive heave-current partis optimized effectively; a through hole through which a rotor wire can pass is arranged in a mandrel of a slip ring, problems as wiring in the device can be solved effectively; wires of a stator part can be output via the side surface, bottom or top, and connected with a static device to solve problems in moving and static rotary switching; a liquid and gas control part and a slip ring signal part are provided with casings respectively to enhance the sealing performance and torsional force of the device, gas leakage is prevented, and integrated liquid, power and gas transmission is realized;and small contact brushes make contact with power copper rings, large contact brushes make contact with the heavy current conductive copper rings, pressure contact between the brushes and the copperrings is controlled to reduce wearing of the copper rings, prolong the service life of the copper rings, and further provide stable signals.

Problems solved by technology

[0002] The currently used hybrid slip rings have unstable rotor sealing performance and torque performance, and are prone to leakage. When high current is supplied, the heat dissipation effect is poor, which seriously affects the stability of the slip ring operation.

In order to solve the problem of rotating and transferring the rotor between dynamic and static, the electric drive part and the liquid-pneumatic drive part are integrated together. However, this design has problems such as inconvenient winding of the equipment, and the rotor cannot simultaneously realize the transmission of liquid-pneumatic power when rotating. ; At the same time, the contact between the fiber brush and the conductive copper ring in the hybrid slip ring currently used is inconsistent, and the conductive copper ring is severely worn under high pressure, and the service life is damaged; the pressure is too small, the contact is not complete, and the signal is easy to lose
