Abstract

An excavator low voltage collection electric ring comprises a DC motor main loop electric ring, a fork-lever, a DC motor excitation loop electric ring and a carbon brush. The DC motor excitation loop electric ring is four rings and the character is that the DC motor main loop electric ring is two wide rings and every pair of wide ring carbon brushes are symmetrically arranged on the center position of the side surface of the wide ring. The spaces between the main electric rings are increased due to the main electric ring of the excavator low voltage collection electricity ring of the utility model being separating to two wide rings and the carbon brush of the low voltage electric ring is hard to shift, which make the usage safer.

Description

Power shovel low pressure collector ring

Technical field

The utility model relates to a kind of power shovel low pressure collector ring.

Background technology

Existing power shovel low pressure collector ring is eight rings, and wherein four rings are DC motor major loop usefulness, and other four little rings are shift fork and DC motor energized circuit usefulness, are installed on the power shovel central shaft, is that power shovel is as fixing with movable electric the contact.Its main ring spacing is less, owing to use under the big environment of power shovel vibration, the carbon brush of low pressure collector ring is shifted easily, and meets on another ring, causes short circuit, burns out major loop ring, carbon brush, brush carrier.

Summary of the invention

The purpose of this utility model just provides a kind of power shovel low pressure collector ring simple in structure, safe in utilization.

Power shovel low pressure collector ring of the present utility model comprises DC motor major loop electricity ring, shift fork and DC motor energized circuit electricity ring and carbon brush, DC motor energized circuit electricity ring is four rings, be characterized in that DC motor major loop electricity ring is two wide rings, each is organized wide ring carbon brush and is symmetricly set on the center, wide ring side.

Power shovel low pressure collector ring of the present utility model strengthens main electric ring spacing because main electricity ring is two wide rings, and the carbon brush of low pressure collector ring is not easy displacement, uses safer.
