Track shock attenuation fastener that stability is good

Technical Field

The utility model relates to the technical field of rail damping fasteners, in particular to a rail damping fastener with good stability.

Background

The railway track is called as rail, track, etc. and is mainly used for railway and cooperates with switcher to make train run without steering. Railway tracks are generally composed of two parallel rails which are fixed to sleepers below which ballast is provided. The rail clamp is fastened by rail supports, fasteners, rail clamps, rail clamp plates, elastic bars, railway spikes and other railway fittings. Railway rails are made of steel and can bear more weight than other materials. The sleeper is also called sleeper, ash sleeper or road sleeper, and is used for dispersing the weight of rail and the pressure applied to rail separately and maintaining the fixed track gauge and the track gauge of rail.

For the known track damping fasteners with good stability, reference is made to the patent numbers: CN214383866U, including track pillow, rail track body is fixed in through elastic fastener on the track pillow, elastic fastener comprises elastic fastener bearing section, arc elastic fastener structure and fastener push down fixed part, and the reference is through designing annular elastic fastener in both ends, as orbital fastener, not only can fix the track, has absorbing effect moreover, reduces the noise that the track produced, but elastic fastener's elasticity is limited, when the pressure value reaches the upper limit or bear pressure time for too long, very easily makes elastic fastener fracture or lose elasticity, and because vibrations lead to the bolt very easily to become flexible, can exert an influence to the cushioning effect of track damping fastener after dropping, stability is relatively poor.

1. Through setting up powerful spring, the elastic fastener bears the weight of the pressure time for too long and very easily makes elastic fastener fracture or lose elasticity, has all increased three powerful spring in the left and right sides of track shock attenuation fastener, and when pressure appears in the top of elastic fastener, powerful spring can share pressure and play absorbing effect, can be better carry out the shock attenuation to the track.

2. Through setting up fixation nut and fixture block, when the bolt carries out fixed mounting to track damping fastener, install fixation nut between bolt and track damping fastener, the fixture block of fixation nut below corresponds rotatory draw-in groove of inserting track damping fastener top, the fixing bolt that can be further when vibrations like this prevents that the bolt from droing because of vibrations.
