Description
Technical field
The utility model is related to rail fastener system, more particularly to splash construction after a kind of fastener system spring is anti-fracture.
Background technology
Fastener system is the important component in the wheel track railway system, and effect is to withhold rail to be fixed on sleeper or rail
On guidance tape, keeps gauge and rail is prevented vertically and horizontally to move, vehicular load is transmitted in substructure, and certain bullet is provided
Property and compatibility of deformation ability.
With the development of railway construction, most of railway uses spring secures rail to sleeper system, generally by spring, backing plate,
The parts such as anchor bolt, spring washer, resilient sleeper-bearing form.Spring provides elastic buckles pressure for fastener system, is fastener system
The critical component of system.Currently, the spring type of application mainly has ω types spring, e types spring, D types spring, fast springs, PR bullets
Item etc..According to the fixed form of spring, being divided into has bolt spring and non-bolt spring.Bolt spring is to pass through spring by bolt
It is fixed on iron seat, and non-bolt spring is then that spring is inserted into the jack on iron seat by special design, passes through its elasticity
Deformation provides pressure fixing on iron seat.Non-bolt elastic bar fastener system for the elastic bar fastener system for having bolt,
Structure is relatively easy, is easy to install and maintain.
Occasionally occur disconnected according to current rail fastener systematic difference situation and the loading characteristic of spring itself, spring
The reason of the case where splitting, fracture, has very much, and as sub-rail foundation deforms, excessive, wheel load load is abnormal, wheel rail system matching is asked
Topic, track resonate, rail wear is abnormal, fastener system installation error is excessive etc..Inevitable, the fracture rate when fracture of spring
It is acceptable to be maintained under certain low ratio situation, but no constraint portions may be caused to sputter after spring fracture
It goes, impact vehicle arrangement even pedestrian causes vehicle damage even to jeopardize safety.It there is no the bullet of effective way limitation fracture at present
Item causes safety accident.In addition, being required according to railway system's technology, fastener system, which generally requires, to be met certain insulation performance and wants
It asks, insulation measures and construction is currently there is no on spring.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of anti-fracture rear splash of fastener system spring to construct, with
It splashes after effectivelying prevent spring to be broken in abnormal cases, while improving the insulation of fastener system under normal usage
Performance.
Technical solution is as follows used by the utility model solves its technical problem：
The anti-fracture rear construction that splashes of fastener system spring of the utility model, including spring ontology, it is characterized in that：The bullet
Covering package flexible protective set on the annular section of ontology, flexible protective set form tight fit connection with spring ontology；It is described
Flexible protective set is arranged along spring ontology overall length, or is set on the bending section that spring ontology is easily broken.
The utility model has the beneficial effects that even if spring ontology is broken, but be wrapped in soft on its outer surface
Property protective jacket will not be broken, by flexible protective cover constraint fracture spring ontology, effectively solve spring ontology fracture after
The problem of splashing or popping up；Since rail and spring ontology are effectively isolated by flexible protective set, fastener system can be increased
Insulation performance；Simple in structure, anti-spring splashing effects are good, install the features such as simple, can effectively avoid causing safety accident
And the insulation performance of fastener system is improved, while the other component structurals of existing fastener system are not influenced；Suitable for any types
Spring, have wide promotion prospect.
Description of the drawings
This specification includes following five width attached drawing：
Fig. 1 is the vertical view (embodiment 1) constructed that splashes after the utility model fastener system spring is anti-fracture；
It is the sectional view (embodiment 2) of line A-A that Fig. 2, which is along Fig. 1,；
It is the sectional view (embodiment 3) of line A-A that Fig. 3, which is along Fig. 1,；
It is the sectional view (embodiment 4) of line A-A that Fig. 4, which is along Fig. 1,；
Fig. 5 is the vertical view (embodiment 5) constructed that splashes after the utility model fastener system spring is anti-fracture.
Component and corresponding label are shown in figure：Spring ontology 1, flexible protective set 2, outer flexible insulating layer 21, fiber increase
Strong layer 22, interior flexible insulating layer 23.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig.1, Fig. 5, the anti-fracture rear construction that splashes of fastener system spring of the utility model, including spring ontology 1, institute
Covering package flexible protective set 2 on the annular section of spring ontology 1 is stated, flexible protective set 2 forms tight fit with spring ontology 1 and connects
It connects.Even if spring ontology 1 is broken, but the flexible protective set 2 being wrapped on its outer surface will not be broken, by soft
Property protective jacket 2 constraint fracture spring ontology 1, effectively solves the problems, such as spring ontology fracture after splash or pop up.Due to soft
Rail is effectively isolated by property protective jacket 2 with spring ontology 1, can increase the insulation performance of fastener system.The utility model has
The features such as simple in structure, anti-spring splashing effects are good, installation is simple, can effectively avoid causing safety accident and improve fastener
The insulation performance of system, while the other component structurals of existing fastener system are not influenced.Suitable for any kind of spring, have
Wide promotion prospect.
Referring to Fig.1, the flexible protective set 2 is arranged along 1 overall length of spring ontology.With reference to Fig. 5, the flexible protective set 2 or
Person is set on the bending section that spring ontology 1 is easily broken.
With reference to Fig. 2, single layer structure may be used in the flexible protective set 2, and flexible protective set 2 is by rubber material or has
The polymer material or other elastic materials of elasticity are made.
With reference to section 3, to enhance protection effect, the flexible protective set 2 can be used double-layer structure, i.e., flexible protective set 2 by
Outer flexible insulating layer 21 and two layers of the compound composition of fiber-reinforced layer 22.With reference to Fig. 4, for enhancing protection effect and insulation performance, institute
It states flexible protective set 2 and can be used three-decker, i.e., flexible protective set 2 is by outer flexible insulating layer 21, fiber-reinforced layer 22 and interior soft
Property 23 3 layers of compound composition of insulating layer.Wherein, the outer flexible insulating layer 21, interior flexible insulating layer 23 are by rubber material or tool
Flexible polymer material is made.
Some originals of splashing construction after the utility model fastener system spring described above that only explains through diagrams is anti-fracture
Reason, be not intended to by the utility model be confined to shown in and the concrete structure and the scope of application in, therefore every be possible to
The corresponding modification being utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
