Abstract

The invention relates to a railway maintenance machine, in particularly to a drainage ditch excavating device for a railway bridge. The drainage ditch excavating device for the railway bridge comprises a supporting arm and an excavating arm, wherein one end of the supporting arm is connected with the screen scarifier, one end of the excavating arm is hinged to the supporting arm, an excavating bucket wheel is installed at the other end of the excavating arm, an excavating motor is further installed on the excavating arm, the excavating motor is connected with the excavating bucket wheel through chain transmission or gear transmission, and an oil cylinder telescopic device is connected between the supporting arm and the excavating arm. The drainage ditch excavating device is fixed to the bottom of the frame, the left side and the right side of the screen cleaning vehicle are each provided with one excavating device, drainage ditch excavating is conducted after screen cleaning and guidegroove excavating and before railway ballast backfilling, railway ballast cleaning of drainage ditch areas on the two sides of a bridge can be achieved, and the ballast bed drainage performance is recovered.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a drainage ditch digging device for a railway bridge. Background technique [0002] The cleaning of existing railway track bed pillow bottoms is carried out by a cleaning machine. Due to the certain slope of the existing bridge pillow bottom, the bridge drainage ditch area cannot be cleaned thoroughly after cleaning by the screen cleaning machine. This means that the excavation guide groove cannot be cleaned by the screen cleaning machine The thickness of the ballast will affect the drainage performance. Contents of the invention [0003] The present invention aims to solve the problem that the existing bridge cleaning machine cannot dredge the bridge drainage ditch when cleaning the bottom of the bridge pillow, and provides a drainage ditch excavation device for railway bridges, which can backfill the ballast after the screen is cleaned and the guide groove is excavated. Prior...
