Small railway maintenance equipment capable of removing and backfilling ballast

Abstract

The invention discloses small railway maintenance equipment capable of removing and backfilling ballast. The equipment is composed of a tamping and blast leveling device, a runway shoulder and ballast bed shape correction device, a grab bucket stone removal device, a ballast centralized removal device, a sleeper end stone removal device, a sprocket stone removal device and a rail car. A working device can be aligned with a working position quickly, ballast between sleepers can be removed quickly, and sandy soil in ballast can be automatically removed at the same time; ballast on a ballast bed outside a sleeper end can be quickly removed; ballast on a ballast bed below a rail can be quickly removed; ballast can be quickly backfilled in the space between replaced sleepers on two sides; the shape of a runway shoulder and a ballast bed can be quickly corrected; ballast backfilled in the space between the replaced sleepers can be quickly tamped and leveled; the equipment can be adapted to linear and bent rail sections for ballast removal and backfilling; automatic control can be achieved, operation is convenient, and ballast removing and backfilling efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a small-scale railway maintenance equipment for ballast discharge and filling. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, some railway sleepers sink and need maintenance. Individual sleepers are damaged and need to be replaced in time. During the sleeper replacement process, manual cleaning and backfilling of ballast are used , time-consuming and labor-intensive, the work efficiency is low, and the work cannot be completed in the effective train passage gap (commonly known as: skylight). Contents of the invention [0003] The purpose of the present invention is to provide small maintenance equipment for ballast-discharging and filling railways. [0004] The present invention is composed of a tamping ballast leveling device, a road shoulder and ballast bed shaping device, a grab stone cleaning device, a ba...
