Description

Technical Field

[0001] The invention relates to the technical field of railway loading and unloading fasteners, in particular to a mechanical automatic loading and unloading fastener for high-speed railways. Background Art

[0002] Railways are usually ballastless tracks. Ballastless tracks refer to track structures that use an integral foundation such as concrete and asphalt mixture to replace the granular gravel roadbed. Compared with ballasted tracks, ballastless tracks avoid ballast splashing, have good smoothness, good stability, long service life, good durability, and less maintenance work. Due to the use of concrete materials, ballastless tracks have excellent anti-settling and deformation properties, high anti-freezing safety, good stability, and reduced subsequent maintenance costs. The ballastless track fasteners commonly used on high-speed railways are WJ-7, WJ-8, and Roosevelt 300-1 fasteners. The above fasteners are all developed based on the background of manual replacement and are not suitable for mechanical operation. The above fasteners have complex structures and numerous components, especially small accessories, which cannot be grabbed and replaced by machines.

[0003] At present, fasteners are usually disassembled and installed by personnel manually. First, the fastener structural accessories are relatively small and numerous, which makes it inconvenient to install and disassemble the fasteners with the help of mechanical tools, resulting in high labor intensity for maintenance personnel. Second, the existing fasteners are usually fastened and fixed to the bottom of the track. During the operation of the track, the force on the left and right sides is unstable, which makes it inconvenient to assist in limiting and fixing the track. Third, the force on the railway track can easily affect the fasteners, causing the fasteners to shake or fall off, affecting the stability and practicality of the fastener fixing the track. Therefore, those skilled in the art provide a high-speed railway mechanical automated loading and unloading fasteners to solve the problems raised in the above background technology.
