A rail unloading structure for a track-laying machine

Abstract

This utility model provides a rail unloading structure for a rail laying machine, relating to the field of rail laying, comprising: a carrying frame, including an upper frame and a lower frame, the carrying frame having length and width directions, the lower frame forming two rail feeding channels in the width direction; a ramp mechanism, located at the rear end of the carrying frame, including a rail guide frame, a fixed frame, and a first telescopic unit, the rail guide frame being hinged to the rear end of the lower frame, the rail guide frame forming two rail connection channels collinear with the rail feeding channels, the fixed frame being located at the rear end of the carrying frame, one end of the first telescopic unit being hinged to the fixed frame, and the other end being hinged to the rail guide frame, the first telescopic unit driving the rail guide frame to rotate; and a rail pushing mechanism, located at the rear end of the rail feeding channels, used to push the rail from the rail feeding channels into the rail connection channels. When rail unloading is required, the rail guide frame rotates, lowering the height between the rail guide frame and the ballastless track bed, providing buffer and support for the rail slippage, avoiding large bending of the rail, and affecting the rigidity of the rail.
