Railway rail automatic grinding device

Abstract

This utility model belongs to the field of rail maintenance technology, specifically an automatic rail grinding device, including a grinding chamber. A support frame is fixedly installed inside the grinding chamber, and an L-shaped fixing plate is fixedly installed on the support frame. An L-shaped limiting plate is slidably installed on the L-shaped fixing plate, a first grinding motor is fixedly installed on the L-shaped limiting plate, and a bidirectional motor is fixedly installed on the L-shaped limiting plate. Threaded rods are fixedly fitted on both drive shafts of the bidirectional motors, and a support plate is threadedly connected to the threaded rods. A second grinding motor is fixedly installed below the support plate, and an electric push rod is fixedly installed on the L-shaped fixing plate. The electric push rod controls the up and down position of the L-shaped limiting plate, and the bidirectional motor controls the distance between the two second grinding motors, allowing the two sets of grinding motors to grind the upper and side surfaces of the rail. This device effectively improves the grinding efficiency of the rail, and workers can stay away from the device.
