Abstract

The invention provides a rail damping fastener, which comprises: a base, which is arranged on a sleeper; the base has a base bottom plate and a base side wall extending laterally from the base bottom plate; A backing plate is arranged on the base, and the floating backing plate has a backing plate bottom plate and a backing plate side wall extending laterally from the backing plate bottom plate; a vertical displacement constraint vibration isolation pad is sandwiched between the between the bottom plate of the backing plate and the bottom plate of the base; the lateral displacement restraint vibration isolation pad is sandwiched between the side wall of the backing plate and the side wall of the base; the bottom of the bolt is arranged in the sleeper, and the bottom of the bolt is Sandwich gaskets and nuts are provided in turn on the top; elastic pressing parts are arranged between the sandwich gaskets and the floating backing plate, and the elastic pressing parts press the rails against the floating backing plate superior. The invention can effectively solve the environmental vibration problem caused by train running.

Description

technical field [0001] The invention relates to a rail fastener, in particular to a rail vibration-damping fastener, in particular to a rail vibration-damping fastener used for rail vibration isolation in urban rail transit. Background technique [0002] While urban rail transit brings convenience to people's travel, the wheel-rail coupling vibration also brings vibration and noise pollution to surrounding buildings and residents. At this time, the use of vibration-damping fasteners on the track is an effective measure to reduce the vibration of the surrounding environment. [0003] At present, the existing various damping fasteners are all using their respective structural forms and methods to control the sinking amount and lateral displacement of the rail. [0004] To sum up, the following problems exist in the prior art: the damping control effect of various existing damping fasteners is not good. Contents of the invention [0005] The invention provides a rail vibrat...
