Double-row multi-roller type modular current-receiving device for electric locomotive

Abstract

Disclosed is a double-row multi-roller type modular current-receiving device for an electric locomotive. According to the double-row multi-roller type modular current-receiving device for the electriclocomotive, two rows of metal rollers are annularly arranged on an insulating base; each rolling wheel is arranged in the manner that two insulating stand columns are fixed to the insulating base, compression springs sleeve the two insulating stand columns correspondingly, insulating blocks sleeve the insulating stand columns and are located above the compression springs, metal shells of the rollers are installed on metal shafts through two insulating bearings, the metal shafts are fixed to the two insulating blocks, the outer surface of an annular current receiving electric brush makes contact with the roller metal shells to receive current, the inner surface of the annular current receiving electric brush is fixed to the metal shafts, all the metal shafts are connected through cables and are then used for supplying power to vehicle-mounted power consuming equipment, and two pure carbon sliding plates are fixed to the insulating base through more than four springs. The friction forceand the friction noise of the current-receiving device and a rigid contact rail can be effectively reduced, and the double-row multi-roller type modular current-receiving device can adapt to the changes of locomotive traction power requirements and has good buffering performance, heat dissipation performance and rail attaching performance.

Description

technical field [0001] The invention relates to the technical field of rail transit power transmission, in particular to a multi-roller type current collector for urban rail electric locomotives used in conjunction with rigid contact rails. Background technique [0002] According to the different ways of rail trains to obtain current, rail transit power supply methods are mainly divided into rigid contact rail power supply and flexible catenary power supply. Among them, the rigid contact rail power supply method has the advantages of occupying less space than catenary laying, stable current quality, relatively less maintenance in the later stage, and good landscape, and is favored by the urban rail transit field. The current collector is installed on the side of the train bogie, and obtains electric energy from the contact rail placed beside the rail. At present, the current domestic traditional rigid rail current collection system usually adopts the power collection method...

AI Technical Summary

Problems solved by technology

[0005] Both of the above two adopt roller contact to receive power, and only in reducing the eccentric wear and friction noise between the current receiving device and the rigid contact rail, and in adapting to the change in the traction rate demand of the rail locomotive, further measures need to be taken for improvement
