Description
Technical field
The present invention relates to rail fastener system, in particular to a kind of spring fly-off prevention structure device for non-bolt fastener.
Background technique
Rail fastening is the chief component of track structure, is the important component for being coupled rail and sub-rail foundation.Fastener
Major function include: (1) keep and adjustment gauge, rail to；(2) longitudinal resistance is provided, rail creeping and brittle fractures of rail are prevented
When breaking joint it is excessive；(3) elasticity is provided, vibration and impact are reduced；(4) increase rigidity of track panel, prevent Track Buckling；(5) it mentions
For track insulation, guarantee that track circuit works normally；(6) there is certain rail high and low position adjustment capability.
Classified according to spring fixed form, common fastener, which can divide, in domestic rail traffic bolt fastening and non-bolt button
Part.E type spring non-bolt fastener is because having the characteristics that simple structure, low cost, maintenance amount are few and buckle press is strong and extensive
For in urban track traffic underground cable and ground line.
Spring is that the core component of buckle press is provided in fastener, and the stress generated by self-deformation is in rail
On, guarantee the stability of rail.In view of spring is readily replaceable component, the failure of individual part will not threaten driving to pacify
Entirely.Therefore, yield range of the equivalent stress control of spring in spring raw material when generally assembling fastener in spring design
It is interior, and spring is allowed small plastic deformation occur.
According to current Rail Fastening in Urban Rail Transit service condition, the case where spring occurs fracture once in a while, cause to break
The reason of splitting includes that the improper installation of spring, sleeper or fastener sky are hung, rail corrugation etc. causes wheel track exciting excessive.Individual springs
Noncontinuity fracture will not influence the stability of rail.But scene discovery spring is based on larger vibration acceleration and is broken feelings
Phenomenon can be flown due to inertia generation under condition energetically, and then cause the secondary disaster of spring impact train, trackside equipment；In addition
, spring of having no progeny falls into switch area with vehicle band extension, there is the material risk for influencing track switch rotation.
A kind of fastener system spring is disclosed in the application for a patent for invention prospectus of notification number CN108316064A
Splash construction after anti-fracture, and anti-splashing construction is the covering package flexible protective set on spring ontology, passes through flexible protective set
The spring ontology of fracture is constrained, to prevent splashing or pop-up after the fracture of spring ontology.But this it is anti-fly construction there are it is following not
Foot: (1) flexible protective set influences the status checkout of spring, cracked or even when being broken in spring, can not visually find,
There are great railway security hidden danger；(3) spring is installed by interference fit, and in its installation position, protective jacket can be in interference pressure
It is fashionable to be destroyed, lead to the weakening or forfeiture of anti-chikung energy.
A kind of anti-winged device of spring is disclosed in the application for a patent for invention prospectus of notification number CN108797231A,
Its structure be using wire rope skeleton connect two installation sets, installation set be individually fixed in " e " type spring face arch orthodrome and after
Encircle at small arc-shaped, realizes that spring is had no progeny from constraint function.The device Shortcomings are can only to be broken at spring orthodrome
Shi Shixian constraint function, when being broken at spring small arc-shaped, which will fail as spring is flown out together.According to
Live spring crack conditions, the fracture of e type spring mostly occur at spring small arc-shaped.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of spring fly-off prevention structure device for non-bolt fastener, with
Ensure that the anti-chikung of spring can be effective, either rail side spring or two sides spring are broken simultaneously, and no matter spring is broken
Face arch orthodrome position or rear arch small arc-shaped position are betided, fracture can be constrained without flying phenomenon.
The technical solution adopted by the present invention to solve the technical problems is as follows:
A kind of spring fly-off prevention structure device for non-bolt fastener of the invention, the including being located at rail both lateral sides
One e type spring, the 2nd e type spring, it is characterized in that: in the face arch orthodrome position two sides of the first e type spring, the 2nd e type spring
Be respectively set down the first wirerope for wearing rail, the second wirerope, the first wirerope, the second wirerope both ends respectively first
E type spring, the 2nd e type spring face arch orthodrome position on therewith binding connection form self-locking system；Except the binding at both ends connects
Connect outside section, first wirerope, the second wirerope section be located in insulation system.
The first e type spring, the 2nd e type spring face arch orthodrome position on axially spaced-apart a pair of of axial constraint is set
Structure, by the first wirerope, the second wirerope binding linkage section position restriction the first e type spring, the 2nd e type spring it is disconnected
Other than knick point.
Compared with prior art, constructional device of the invention has significant progress in the anti-winged performance of spring, beneficial
Effect is embodied in following aspects:
1, the anti-chikung of spring can be effective, either rail side spring or two sides spring simultaneously be broken, no matter bullet
Item fracture betides face arch orthodrome position or rear arch small arc-shaped position, and it is existing without flying can to constrain fracture
As；
2, spring surface does not influence spring appearance test without covering, spring fracture occurs or when micro-crack can and
Shi Faxian；
3, constitutional detail is few, and installation effectiveness is high, and material cost and construction cost are low；
4, it has no adverse effect for fastener other component stress；
5, it is suitable for all kinds of e type spring non-bolt fasteners, including new line design and Existing railway promotion.
