RAILWAY TRACK STABILIZING DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/101320

Kind Code:

A1

Abstract:

A railway track stabilizing device, comprising a main vehicle frame, a vibration-excitation portion (1), a box body (2) and a driving motor, and the box body is connected to a bottom part of the main vehicle frame via a retractable oil cylinder (301). The vibration-excitation portion is installed inside the box body, the vibration-excitation portion comprising a driving shaft (11), a second vibration-excitation shaft (12) and a third vibration-excitation shaft (13) arranged in parallel; two ends of the driving shaft, the second vibration-excitation shaft and the third vibration-excitation shaft are respectively and rotatably installed on the opposite front wall and back wall of the box body, and the driving shaft is above and between the second vibration-excitation shaft and the third vibration-excitation shaft; a first eccentric block (121) fixedly sleeves the second vibration-excitation shaft, and a second eccentric block (131) fixedly sleeves the third vibration-excitation shaft; if the swing directions of the first eccentric block and the second eccentric block are in a horizontal direction, then the swing directions of both are on the same side; if the swing directions of the first eccentric block and the second eccentric block are in a vertical direction, the swing directions of both are opposite. The track stabilizing device addresses the technical problems of higher height of the stabilizing device and less obvious stabilization effect to the track bed caused by the long distance from the centroid height of the exciter of existing stabilizing device to the rail surface.
