Description
Technical field
The invention belongs to technical field of rail traffic, the concrete manufacture method proposing the double-deck track switch Damping fastening system of a kind of separate type.
Background technology
The current track switch Damping fastening of China mainly contains three kinds of structure patterns, is sulfuration base+iron chair form, double-deck sulfuration type fastener, vibration damping track switch base systems respectively.
Namely sulfuration base+iron chair formula fastener adopts the damping base of sulfuration adhesion type as damper unit, adopts track switch fastener iron chair as rail connective element; Sulfuration base be by upper iron plate and lower iron chair by the mode of the vulcanization of rubber, make iron plate and lower iron chair bonding be an inseparable entirety, double-deck sulfuration type fastener structures and the mechanism of action and sulfuration base+iron chair formula fastener are similar; Vibration damping track switch base systems devises three layers of iron chair, overall by mechanical type bind mode, it is achieved that the detachable design of iron chair and damper unit.
Several fastener pattern is implemented and in onsite application process, main problem has in two producing above: its one, track switch region fastener pattern is more, and above several fastener pattern all needs out many sleeve formings mould, costly; Its two, the metalwork of above several form all adopts casting and molding method, casting backing plate product planeness wayward, the casting of especially long backing plate; The planeness of fastener also can be affected because of the injustice of cast member; Train is when turnout passing different zones, and track switch resistance to overturning is poor, increases the maintenance work of trouble district track component, makes troubles to on-the-spot operation maintenance.
In patent (ZL201220682492.3), it is proposed that a kind of easy dismounting separate type double-layer vibration damping fastener for common rail section; This structure adopts upper and lower iron chair self-locking to connect, and easily dismounting, manufacture simply, but do not relate to track switch vibration damping section, do not mention welding fabrication yet.
In patent (ZL201420515221.8), it is proposed to a kind of vibration damping track switch base systems. Although this system solves part replacement problem, but which employs three layers of iron chair structure, cost height, component are many, complex structure, are unfavorable for in-site installation and maintenance service.
In patent (ZL201120345928.5), it is proposed to a kind of track traffic, with replaceable steel rail vibration damping fastener, can conveniently realize the replacing of fastener component;But the upper and lower iron chair of this fastener realizes connection by spring, and system stability is not good enough.
