Automatic sleeper replacing machine with tamping and ballasting device

Abstract

The invention discloses an automatic sleeper replacing machine with a tamping and ballasting device. The automatic sleeper replacing machine is composed of the tamping and ballasting device, a shoulder and ballast bed trimming device, a grab bucket stone-removing device, a ballast collecting and discharging device, a sleeper end stone-removing device, a sprocket stone discharging device, a four-nut synchronous assembling and disassembling device, a rail lifting device, a sleeper-rotating and sleeper pushing-and-pulling device, a sleeper hoisting device, a generator, a hydraulic system and control system cabinet and a rail car. According to the automatic sleeper replacing machine, the working devices can be aligned with working positions rapidly; ballast between sleepers, ballast outside the ends of the sleepers and ballast on a ballast bed under steel rails are automatically discharged, sand in the ballast is automatically separated, the ballast is automatically backfilled into the space between sleepers on the two sides of a replaced sleeper, tamped and flattened through vibration, and the shapes of shoulders and the ballast bed are automatically restored; four-nut synchronous assembling and disassembling are achieved, the fatigue lives of bolts are prolonged, and connection reliability of the sleepers and the steel rails is guaranteed; and the sleeper-rotating and sleeper pushing-and-pulling device is an integrated device, is compact in structure, adapts to various operations of sleeper replacing of linear and curved railway sections and is high in sleeper replacing efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an automatic pillow changing machine with a tamping and ballast leveling device. 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. In the process of sleeper replacement, manual work is used, which is time-consuming and laborious. , 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 an automatic pillow changing machine with a tamping and leveling device. [0004] The present invention consists of a tamping ballast leveling device, a road shoulder and ballast bed modification device, a grab stone cleaning device, a ballast collection and disch...
