Abstract
A kind of new railway rail pad, the railway rail pad (1) include backing plate (2), it is characterised in that and the backing plate (2) is foaming structure, wherein, backing plate (2) both sides set rib (3) along sleeper direction.It can be very good solve the problems, such as that slab construction rigidity is excessive by railway rail pad provided by the utility model.Meanwhile due in the absence of groove, being also just not present, backing plate edge turns up slab construction, backing structure has stress concentration point, produces the problem of tearing phenomenon.
Description
Technical field
It the utility model is related to rail transport field, more particularly to a kind of new railway rail pad.
Background technology
Rail clip is made up of parts such as spring, screw spike, railway rail pad, gauge apron, track gauge block, nut, packing rings.
Wherein railway rail pad is the important component for ensureing track elasticity, primarily serves the effect of buffering and damping.Backing plate is using process
In rolled and impacted by locomotive, vehicle incessantly, become one of part that damage is easiest in each part.Especially
The special sharp radius curve of 3 in Curve Segment compared with the impact suffered by straight line location, roll and push more prominent.
Rubber mat plate damage problem is very serious at present, and the service life of General Purpose Rubber backing plate is often other general section pads
Plate service life part is to ten parts, wherein most short backing plate service life only 5 days.Use instead afterwards and add reinforcement
Rubber mat plate, situation improve also unobvious.Present rubber mat plate service life is generally 18 months, and indivedual serious part of paths use week
Phase is 12 months.
Existing railway rail pad, generally using groove structure, passes through change because material foam process itself is complicated
Free area also adjusts the Static stiffness of backing plate.Situation is destroyed by field observation backing plate, the failure mode of most of backing plate is presented
Face checking, the phenomenon of abrasion.Think the grinding pressure that backing plate marginal position can be longitudinally combined by very big transverse direction,
Backing plate edge situation about turning up easily is occurred, cause the groove corner position of backing plate that stress concentration point occurs, make rubber material
Material is in close to right-angle tearing state, typical backing plate robber materialses angle tear strength only 20N/mm, according to the backing plate length of side
185mm is calculated, and general backing plate is only capable of bearing about 3700N tear force value, and far smaller than backing plate is in the transverse direction suffered by curve section
Power and vertical force.Lancinating destruction makes backing plate lose resilience, is further exacerbated by backing plate destruction.
Utility model content
To overcome the drawbacks described above of prior art, the utility model provides a kind of new railway rail pad, the railway rail pad bag
Backing plate is included, the backing plate is foaming structure, wherein, backing plate both sides set rib along sleeper direction.
Wherein, the pad surfaces set reticulate structure.
Wherein, uniform stomata is distributed with inside the backing plate.
Wherein, the relatively described backing plate of the rib, which is compared, has higher wear resistance.
The utility model can be very good solve the problems, such as that slab construction rigidity is excessive relative to same type railway rail pad.
Meanwhile due in the absence of groove, being also just not present, backing plate edge turns up slab construction, backing structure has stress concentration point, produces
The problem of raw tear phenomenon.
Brief description of the drawings
Fig. 1 is railway rail pad structural side view.
Fig. 2 is rail plate surface reticulate structure figure.
Fig. 3 is rail intralamellar part structure chart.
Embodiment
New railway rail pad provided by the utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of new railway rail pad, the railway rail pad (1) includes backing plate (2), and the backing plate (2) is foam
Structure, wherein, backing plate (2) both sides set rib (3) along sleeper direction.
Shown in Fig. 2, backing plate (2) surface sets reticulate structure (21).A large amount of sharp radius curves in existing sole-plate
There is play phenomenon in backing plate, is primarily due to frictional force deficiency between backing plate resilience deficiency and backing plate and rail and causes, leads to
Increase pad surfaces frictional force and the aspect measure of increase backing plate rib two are crossed to solve.
Due to taking slab construction, the skin-friction force of backing plate may further decline, therefore, we attempt padding
Plate surface adds reticulate structure, and slight reticulate pattern can effectively increase pad surfaces frictional force, again will not be in pad surfaces
Form stress concentration point and influence the anti-wear performance of backing plate.
As shown in figure 3, uniform stomata (22) is distributed with inside backing plate (2).Rubber mat plate uses groove structure master at present
If because elastomeric material is not foaming system.The rubber mat plate rigidity of flat board not foaming structure is excessive, it is therefore necessary to passes through ditch
Slot structure control pad panel stiffness, ensure the damping performance of backing plate.If using foaming structure, uniform gas is distributed with backing plate
Hole, it is possible to solve the problems, such as that slab construction rigidity is excessive well.
It can be very good solve the problems, such as that slab construction rigidity is excessive by railway rail pad provided by the utility model.Together
When, due in the absence of groove, being also just not present, backing plate edge turns up slab construction, backing structure has stress concentration point, generation
The problem of tearing phenomenon.
Finally it should be noted that above example is only describing technical scheme rather than to this technology method
Limited, the present invention can above extend to other modifications, change, application and embodiment, and it is taken as that institute in application
There are such modification, change, application, embodiment all in the range of the spirit or teaching of the present invention.
