Description
Technical field
The utility model belongs to technical field of rail traffic, specifically proposes a kind of double-deck non-linear fastener of low-mounting height
System.
Background technology
The common medium vibration damping mode of the current underground railway track traffic in China mainly uses double-deck nonlinear vibration reduction fastener,
The fastener has withdrawal resistance high relative to traditional adhesion type fastener, and security is good, and many advantages such as performance is stablized, are widely used in
Multiple important track traffic cities.
Traditional bonding by Vulcanization type fastener be by upper iron plate and lower iron chair by way of the vulcanization of rubber, make iron plate and
Lower iron chair bonding is an inseparable entirety；Double-deck non-linear fastener is then entirely through mechanical bind mode, is adopted
Upper and lower iron chair is locked with nylon jacket rotation mode, the detachable for realizing iron chair and damper unit designs.
The mode that double-deck non-linear fastener is combined as a result of two layers of iron chair, upper and lower iron chair Shanghai is respectively provided with
Rubber pad and intermediate rubber backing plate under rail, it is general under fastener to be also placed with coupling backing plate etc., therefore also there are following two for the fastener
A optimizable direction：First, the design method of sandwich plate make it that the setting height(from bottom) of fastener is higher, there are during the transformation of old line
Need to set changeover portion, or rail is adjusted；Second, to ensure safety, the volume of metal caul is larger, and plank is more
It is thick and heavy, it is difficult to reduce cost.
In patent (CN201220682492.3), it is proposed that a kind of readily removable assembled separation type double-layer vibration damping fastener system；Carry
A kind of readily removable assembled separation type double-layer vibration damping fastener system gone out, includes elastic insulated pad, upper plate, bottom plate bullet under spring, rail
Property felt pad, lower plate and anchor bolt；Boss possessed by lower plate, through the through hole on upper plate；It is nested with boss
Bottom plate connector sleeve after boss rotation, the connection that is combined of convex-concave is formed with the boss on lower plate or with lower plate, the bottom of to
Plate connector sleeve carries out axial limiting, and bottom plate connector sleeve interlocks under mutual interlocking gear effect with boss in radial direction；Bottom plate connects
The upper eaves portion position of female connector is withheld on upper plate top, is fastened on by interlocking cover board by anchor bolt on railway roadbed.The fastener system
Take into full account that upper and lower iron chair and its intermediate member are all in flat features of shape, the upper eaves of bottom plate connector sleeve during fixed connection
The plane of portion and upper plate is withheld, and is fixed on upper and lower bottom plate using the interlocking of boss and bottom plate connector sleeve with lower plate one
Together, the stability of upper and lower bottom plate connection is effectively increased.But iron chair places rubber pad up and down in the fastener of the present invention
Part, surface is smooth, there is no depression situation about digging pit, therefore setting height(from bottom) be two layers of iron chair, two layers of rubber mat plate and
Other are used cooperatively the thickness of slab summation of backing plate.
In patent (CN2630303Y), a kind of self-locking rail two-layer vibration-damping noise-reducing fastener, including spring, insulation are proposed
Rubber pad placed under-neath rail is arranged at pad, the top of upper iron plate, and middle spring pad is placed with below upper iron plate, lower iron pad is placed with below cushion
Plate, upper and lower iron chair are locked together by the self-locking structure being composed of two resilient sleeves.Although some difference of self-locking mechanism,
But iron chair places the part of rubber pad up and down in the fastener of the present invention, and surface is smooth, therefore setting height(from bottom) is two layers of iron pad
Plate, two layers of rubber mat plate and other be used cooperatively backing plate thickness of slab summation, be not directed to reduce rail setting height(from bottom).
In patent (CN205134109U), a kind of upper buckle type shock-absorption fastener system, including rubber under spring, rail are proposed
Backing plate, upper and lower iron chair, intermediate rubber backing plate etc..Rubber tie plate under rail, upper strata pad are provided between rail and upper strata iron chair
Intermediate rubber backing plate is provided between plate and lower floor's backing plate, upper and lower iron chair is mechanically connected by nylon self-locking set.Wherein
Counter sink is set on upper iron chair so that nylon is concordant with the upper surface of upper iron chair from the upper surface of lock tube.But the present invention's
Iron chair places the part of rubber pad up and down in fastener, and surface is smooth, therefore setting height(from bottom) is two layers of iron chair, two layers of rubber
Backing plate and other be used cooperatively backing plate thickness of slab summation, be not directed to reduce rail setting height(from bottom).
The above prior art all studies Damping fastening system, steady to improve structure by improving fastener system
It is qualitative.But the problem of not considering rail setting height(from bottom).Common non-Damping fastening is generally individual layer backing plate, therefore double-deck non-thread
Property fastener generally existing setting height(from bottom) it is higher the problem of, just needed in the old line improvement project of subway it is extra transition circuit is set,
Extend the construction period.To sum up, the non-linear fastener system setting height(from bottom) of existing bilayer is high, it is of high cost the problems such as be that this area is wished for a long time
Hope the technical problem solved.
In view of this, the utility model is proposed.
