Abstract

The invention relates to the field of public works rail cars, in particular to a special electric drive public works rail car for high-speed railway, aiming at solving the technical problem that the existing public works rail cars cannot meet the high-efficiency, fast and clean line maintenance task of the high-speed railway. The running part comprises a driven bogie and a power bogie respectivelyarranged at the front and rear ends of the bottom of the vehicle frame, and the driven bogie and the power bogie are respectively provided with a driven wheel set and a driving wheel set; The power part comprises a diesel generator set fixed on the vehicle frame and a rectifier, wherein the rectifier is electrically connected with a DC traction motor fixed on the power bogie, and the output shaftof the DC traction motor is connected with the driving wheel set. The bottom of the vehicle frame is fixed with a control device between the driven bogie and the power bogie. One end of the control device is electrically connected with the control platform and the other end is electrically connected with the power part. The lifting part comprises an onboard crane and a loading platform.

Description

technical field [0001] The invention relates to the field of rail cars for public works, in particular to an electric drive rail car for public works dedicated to high-speed railways. Background technique [0002] The National Railway Administration’s overview of high-speed railways is: design a dedicated railway for passenger trains with a running speed of more than 250 kilometers per hour and an initial operating speed of more than 200 kilometers per hour. The public rail cars used on high-speed railways are mainly used for the transportation of materials, tools and personnel in line maintenance. With the rapid development of domestic passenger dedicated lines and high-speed rail, the traditional hydraulic transmission and mechanical transmission railway vehicles can no longer meet the tasks of efficient, fast and clean line maintenance. Contents of the invention [0003] The invention aims to solve the technical problem that the existing public works rail car cannot me...
