Sleeper changer with grab bucket stone removing device

Abstract

The invention discloses a sleeper changer with a grab bucket stone removing device. The sleeper changer is composed of a tamping and ballast leveling device, a runway shoulder and ballast bed shape correcting device, the 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 first rail lifting device, a transfer rail and sleeper pushing and pulling device, a sleeper lifting device, a generator, a hydraulic system, a control system box and a rail car. The sleeper changer disclosed by the invention can quickly align the working position of a working device, automatically discharge ballasts among the sleepers, on the outer sides of the sleeper ends and in the ballast bed below the rail, automatically separate sandy soil in the ballast, automatically backfill the ballast between two sides of the changed sleeper to be tamped and leveled and automatically repair the shapes of the runway shoulder and ballast bed; four nuts are synchronous assembled and disassembled, the fatigue lives of the bolts are prolonged, and the connecting reliability of the sleeper and the rail is ensured; the transfer rail and the push-pull sleeper are an integrated device, so that the sleeper changer is compact in structure, suitable for various work of changing the sleepers in straight line and curved line rail sections, and high in sleeper changing working efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing machine with a grab stone cleaning device. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, some railway sleepers sink and need to be maintained. Individual sleepers are damaged and need to be replaced in time. In the process of sleeper replacement, artificial ballast is 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 a pillow changing machine with a grab stone cleaning 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 discharge device, a pillow en...
