Description

A kind of vibration damping track switch base systems and assemble method
Technical field
The invention belongs to field of urban rail, be specifically related to a kind of vibration damping track switch base systems.
Background technology
In railway switch district, the situation of two strands or multiply rail cross-combining will inevitably be there is.In switch zones, adjacent two bursts distances of intersecting between rail can constantly occur to become change, and these specifications and models just causing the track switch fastener of supporting rail are various, bring difficulty to the Vibration Absorption Designing of switch zones, manufacture, installation, replacing.
The vibration damping track switch fastener that China adopts at present, mostly is the form of the snubber base+track switch fastener base assembly of bonding by Vulcanization type.Namely adopt the snubber base of bonding by Vulcanization type as damper unit, adopt track switch fastener base as rail positioning unit.The snubber base of bonding by Vulcanization type is by upper plate and the lower shoe mode by the vulcanization of rubber, make upper plate and lower shoe bonding be an inseparable entirety, as shown in Figure 10.Process screwed hole by the diverse location at snubber base, and by bolt, snubber base is connected as a whole with the track switch fastener base of different structure form, kind, formed and can locate the vibration damping track switch base systems that rail possesses again vibration-damping function.But adopt said structure to there is following shortcoming.
First, the snubber base cost of bonding by Vulcanization type is very high.Track switch fastener base is of a great variety, connection dimension differs, although reduce the kind of snubber base by optimal design as far as possible, general one group of simple turnout still needs the snubber base of at least four kinds of physical dimensions.So, not only need to make multiple baroque space multistory formula bonding by Vulcanization mould, also will formulate complicated sulfuration process, manufacturing cost improves greatly.
Secondly, the snubber base replacing maintenance cost valency of bonding by Vulcanization type is high.Bonding by Vulcanization type snubber base, owing to have employed integral structure, is damaged once possess structure, and for single part replacement, and must can not remove completely, this also makes the replacing maintenance cost of bonding by Vulcanization type snubber base higher.
Finally, the connected mode of snubber base and track switch fastener base is reasonable not.In order to coordinate the track switch fastener base of variety classes and structure, need the independent thread mill drilling of the diverse location on snubber base; And once the positional precision of screwed hole on snubber base is inadequate, whole track switch fastener will be caused to assemble, cause snubber base to scrap.Meanwhile, after screwed hole position is fixing, the relative position of track switch fastener base and snubber base will be completely fixed, and each other without any the space of adjustment, makes troubles to in-site installation construction.
In patent (ZL201220682492.3), propose a kind of quick detachable separate type double-layer vibration damping fastener for common rail section.This structure adopts upper and lower bottom plate self-locking to connect, and quick detachable, manufacture simply, but does not relate to track switch vibration damping section.
