Automatic walking efficient railway ballast stone leveling machine

Abstract

The invention discloses an automatic walking efficient railway ballast stone leveling machine. The railway ballast stone leveling machine is composed of a power travelling wheel, a frame, a stone removing mechanism, a driven travelling wheel, a sweeper, wherein the frame is formed by welding steel and fixing bolts, and is a framework of the railway ballast stone leveling machine; the power travelling wheel, the stone removing mechanism, the driven travelling wheel, the sweeper are fixed on the frame and plays a role in supporting, the stone removing mechanism is a main working mechanism of therailway ballast stone leveling machine and is an executing mechanism for paving ballast stones, the driven travelling wheel is an auxiliary mechanism walking by the railway ballast stone leveling machine, and the sweeper is used for cleaning gravels on the a sleeper of a rail. The railway ballast stone leveling machine is a kind of equipment for paving the railway ballast stone, the railway ballast stone can be automatically paved, and the labor intensity of workers is relieved.

Description

Technical field [0001] The invention relates to the technical field of railway construction, in particular to a railway ballast leveling machine with automatic walking and high efficiency. Background technique [0002] The rapid development of society and economy in my country has put forward higher and higher requirements for railway transportation. Fast, safe and comfortable high-speed railways and heavy-duty railways with intensive transportation and large capacity have become the main trends in the development of railways in my country. The operation and management of the track put forward severe tests. The operation practice of ballasted tracks at home and abroad shows that with the increase of transportation volume, traffic density, axle load and driving speed, the speed of deterioration of track geometry caused by ballast wear and pulverization will increase exponentially, greatly increasing the workload of line maintenance and repair , Which further intensifies the contra...

However, when the ballast stones are transported to the rails, the ballast stones will be directly unloaded on the rails, so that the ballast stones on the rails will be scattered in a large area, and there will be a lot of ballast stones on the sleepers. It can run normally on the railway track, but it is not allowed to have ballast stones on the sleepers, which will hinder the running of the train. At the same time, if the ballast stones between the sleepers are not smooth, it will also affect the train, and it will not be very good at the same time. At this time, it is necessary to clean up the ballast stones on the sleepers, and push the ballast stones between the sleepers to make them in a flat state. This kind of work was often handled by railway workers in the past, which would It consumes a lot of manpower and material resources, not only wasting time but also a lot of labor, so there is an urgent need for a kind of equipment that can automatically complete the work of leveling ballast on the rails

However, existing crushed stone leveling devices have some shortcomings during use. Most of them use screeds. However, there are certain shortcomings in the setting of screeds. It is subject to certain resistance and cannot be buffered in time. Even if some leveling machines can buffer in time, the elastic layer can buffer and damp the leveling plate, reduce the reaction force on the leveling plate, and cause the leveling machine to be flat Insufficient strength, incomplete and incomplete leveling, and it is easy to cause serious wear of the leveling plate, which greatly reduces the service life of the leveling machine. Reduced the difficulty of leveling machine work

Some tempering machines have a small working range and the same working height, which cannot be adjusted, making the work content single
