Self-powered metro steel rail grinding wagon

Abstract

The invention provides a self-powered metro steel rail grinding wagon. A grinding wagon group comprises a hydraulic transmission grinding wagon A1 and a hydraulic transmission grinding wagon A2 which are connected through an automatic car coupler; a steel rail is subjected to coarse grinding through the hydraulic transmission grinding wagon A1; the steel rail is subjected to fine grinding through the hydraulic transmission grinding wagon A2; the hydraulic transmission grinding wagon A1 and the hydraulic transmission grinding wagon A2 are in the same structures; the motion direction of the hydraulic transmission grinding wagon A1 is forward; the motion direction of the hydraulic transmission grinding wagon A2 is backward. The whole grinding wagon group is in a hydraulic transmission mode, each section of a train is self-powered, the rail head surface of the steel rail can be ground by a grinding motor on a grinding device in the low-constant-speed operating process at the speed of 3-15km / h, and the defects such as wave-shaped steel rail abrasion, excess steel rail edges, saddle-type abrasion, welding depression and scale cracks are eliminated, so that the outline of a rail head operating part is improved.

Description

technical field [0001] The invention belongs to the technical field of railway rail cars, and in particular relates to a self-powered subway rail grinding car. Background technique [0002] In recent years, my country's urban subway transportation has achieved leapfrog development. In order to ensure the safe operation of the line, it is necessary to strengthen the maintenance and repair of the rails. The existing technology usually uses two rail grinding vehicles without self-service power towed behind one bullet train. To repair the rails, the maximum operating speed of this type of vehicle is 60km / h, and when grinding the rails, if there is an unexpected situation and needs to drive away from the rails in time, the speed is relatively slow. The worst case is that if the tractor fails, It is necessary to send other vehicles to rescue in addition. Today, when the train is running at a high speed, these accidents will greatly affect the safe operation of the railway line, so i...

The worst case is that if the tractor fails, It is necessary to send other vehicles to rescue. Today, when trains are running at high speed, these unexpected situations will greatly affect the safe operation of railway lines, so it is necessary to propose improvements
