Abstract
It the utility model is related to and a kind of possess anti-rail and topple the spring of function, the spring is integral shell fragment, including the spring middle finger (1), spring heel end (2), spring toe-end (3) and spring extension (4) set gradually, wherein, described spring extension (4) is to be formed after spring toe-end (3) extends along toe-end bending.Compared with prior art, the utility model is simple in construction, easy to assembly, after mounting, extension and the groove match on pre-buried ironcasting, so as to realize the limitation to spring transition deformation, realizes the ability that anti-rail topples.
Description
Technical field
Railroad track field is the utility model is related to, more particularly to a kind of possess anti-rail and topples the fastener assemblies of ability.
Background technology
When vehicle orbits, due to the local irregularity such as track transverse direction irregularity and rail gap, it is likely that to rail
Produce larger cross force.Cross force is excessive easily to cause rail to topple, and leads to traffic accident.Particularly with curved section silent partners,
Inertia force acts on rail by train wheel caused by train pull weight, makes rail by an additional longitudinal masterpiece
With so as to forming larger transverse horizontal component on rail, making rail turn up, cause to topple.Traditional fastener system is not
Can solve the problems, such as that resisting rail topples, can only be by setting rail brace or other mechanisms to arrive and realize.Existing rail brace is direct
It is anchored on rail, it is necessary to drilled on rail, reduces the intensity of rail；Or withheld by spring, once spring fails, rail brace
Also it is ineffective.
The content of the invention
The purpose of this utility model be exactly in order to provided the defects of overcoming above-mentioned prior art to exist it is a kind of it is simple in construction,
Other parts need not be set up, can practical conventional mounting instrument installed, the strong anti-rail that possesses of stability topples work(
The spring of energy.
The purpose of this utility model can be achieved through the following technical solutions：A kind of possess anti-rail and topple the bullet of function
Bar, it is characterised in that the spring is integral shell fragment, including spring middle finger, spring heel end, spring toe-end and the bullet set gradually
Bar extension, wherein, described spring extension is to be formed after spring toe-end extends along toe-end bending.
Described spring extension and the angle of spring toe-end planar are 90 ° ± 10 °.
Described spring extension has certain angle β, angle β models with the plane that spring toe-end is formed and horizontal plane
It is trapped among 0 ° -4 °.
The length of described spring extension is advisable with extension end close to spring middle finger, and the two spacing is in 0mm-
4mm。
Above-mentioned spring realizes the limitation to spring deformation by the cooperation with built-in fitting.
Compared with prior art, the utility model advantage is simple in construction, need not set up other parts, can be practical
Conventional mounting instrument is installed, and stability is strong.

In figure：1st, spring middle finger；2nd, spring heel end；3rd, spring toe-end；4th, spring extension.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1-2, a kind of to possess anti-rail and topple the spring of function, the spring is integral shell fragment, including successively
Spring middle finger 1, spring heel end 2, spring toe-end 3 and the spring extension 4 of setting, wherein, described spring extension 4 is
Along 90 ° of formation of toe-end bending after the extension of spring toe-end 3.The plane and water that described spring extension 4 is formed with spring toe-end 3
Plane has certain angle β, and angle β scopes are at 11 °.The length of described spring extension 4 is connect with extension end
Short round bar middle finger 1 is advisable, and the two spacing is in 2mm.
Specific purpose tool should be used during above-mentioned spring installation, is matched with the embedded iron on rail sleeper, embedded iron is vertical
Cast in the concrete sleeper of usual structure, built-in fitting bottom is submerged in sleeper completely, the upper surface in built-in fitting intermediate layer with
Sleeper upper surface flush.The spot cleared up on sleeper, railway rail pad, steel rail laying are placed, need to place suitably according to gauge
Insulation rail distance keeper.Spring middle finger 1 is inserted in the spring hole of embedded iron, it is impossible to and it is crooked, ensure that fulcrum and reinforcing point are correct, firmly
It is moderate.Threshold value 8-10mm is with embedded iron on the inside of its minimum circular arc and be defined in spring optimum position in place；Spring simultaneously
Extension 4 is completely within built-in fitting groove.
Once spring extension 4 tilts, its deformation failure is limited by built-in fitting groove can, simple and convenient, effect
Fruit is good.
Embodiment 2
A kind of possess anti-rail and topple the spring of function, and the spring is integral shell fragment, including in the spring set gradually
Finger, spring heel end, spring toe-end and spring extension, wherein, described spring extension is edge after spring toe-end 3 extends
80 ° of formation of toe-end bending.
There is certain angle β, angle β to be for described spring extension and the plane that spring toe-end is formed and horizontal plane
14°.The length of described spring extension is advisable with extension end close to spring middle finger, and the two spacing is in 0mm.
Embodiment 3
A kind of possess anti-rail and topple the spring of function, and the spring is integral shell fragment, including in the spring set gradually
Finger, spring heel end, spring toe-end and spring extension, wherein, described spring extension is edge after spring toe-end 3 extends
100 ° of formation of toe-end bending.
Described spring extension is 0 ° with the plane that spring toe-end is formed and horizontal plane angle β.Described spring prolongs
The length of extending portion point is advisable with extension end close to spring middle finger, and the two spacing is in 4mm.
Above-described is only preferred embodiment of the present utility model.It is all the spirit and principles of the utility model it
It is interior, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
