Abstract
Description
Technical Field
[0001] This utility model belongs to the field of current collectors, specifically, it relates to a rolling current collector structure for rail transit. Background Technology
[0002] Current collectors are important system components of rail transit bogies. They collect current by contacting the power supply rail, thereby providing power to the vehicle's drive, lighting, and auxiliary systems. The main components of the current collector system include the current receiving shoe, grounding shoe, matching cable, and clamp. The current collector is installed on the bogie and contacts the rail power supply rail via a carbon slider. The carbon slider and the power supply rail are in constant contact during vehicle operation, generating wear dust that pollutes the rail posts and the environment, affecting the appearance.
[0003] To address the aforementioned problems, patent document 112061986A discloses a crane receiver, comprising: a slider, a receiver bracket, a conductive copper plate, a conductive braided copper strip, a fall-prevention steel wire rope, and a receiver fixing component. The receiver bracket has an irregular shape, including a top horizontal surface, two side surfaces connecting the horizontal surface on the left and right sides, and a square plate connecting the two side surfaces. The slider is mounted and connected to the two side surfaces of the receiver bracket. The conductive copper plate is fixedly mounted on the square plate of the receiver bracket. The conductive braided copper strip has a curved structure, with one end mounted and connected to the conductive copper plate and the other end mounted and connected to the slider. The fall-prevention steel wire rope has one end mounted and connected to the conductive copper plate and the other end mounted and connected to the slider. The receiver fixing component is mounted and connected to the top horizontal surface of the receiver bracket, but this does not solve the aforementioned problems. Utility Model Content
