Auxiliary leveling device for railway ballast laying

Abstract

The utility model relates to railway ballast laying technical field, and disclose the auxiliary leveling device is used in railway ballast laying, including support frame, the surface of one side of support frame upper end bottom is provided with replacement structure, the other side of support frame upper end bottom is provided with anti -loss structure. The utility model discloses by pulling the plug -in rod upwards, so that the one end of plug -in rod is separated from the inside of positioning hole, at this moment can draw out the screed outward, so that the screed is separated from the outer surface of connecting plate, then can set up the screed that has not been used on the outer surface of connecting plate, and loosens the plug -in rod so that the plug -in rod is under the self elasticity of first spring and resets automatically, thereby make the one end of plug -in rod set up in the inside of positioning hole, position the position of screed on the outer surface of connecting plate, and then can only replace the screed, and it is more time -saving and labor -saving, improves the practicality of device to a certain extent.
