Spiral bar, is equipped with pressure block at the top and bottom of the spiral bar, and the protective device side is equipped with the first cavity, and described first
Cavity top is equipped with the second cavity.
Preferably, the salient point quantity is arranged to multiple, and the shell is made of elastomeric material.
Preferably, the pressure block is made of PVC material.
Preferably, first cavity inside is equipped with colloid, and the colloid is made of elasticity heat absorption colloidal materials.
Preferably, slow pressure is equipped with the inside of second cavity to pierce, the slow pressure thorn quantity is arranged to multiple.
Preferably, cylinder is shaped in the middle part of first cavity, the first cavity both ends shape is disposed as
It is spherical.
The technique effect and advantage of the utility model：The utility model is conducive to prevent backing plate from pacifying by setting salient point
Because train is moved by the vibrations backing plate of generation after dress, the frictional force of pad surfaces is improved, reduces sidesway situation
Generation, by setting spiral bar, be conducive to backing plate be unlikely in shock absorbing process produce deformation so that backing plate maintains necessarily
Intensity, improve train by when stability, by setting the shell of rubber material, be conducive to backing plate and reach in use
Wear-resisting, corrosion-resistant, water-fast, oil resistant, heat-resisting, pressure-resistant, impact resistance, elasticity are good, not flexible type and other effects after sizing, by setting the
One cavity and colloid, are conducive to the heat of the absorption pad intralamellar part of maximum function so that backing plate constant temperature, adds backing plate
Service life, reduces the number of backing plate replacement, and thorn is pressed by setting the second cavity to ease up, and is conducive to increase the damping effect of backing plate
Fruit so that the vibrations that train produces during greatly weaken, and ensure that the normal operation of train so that when train passes through
Become more stable.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
The utility model provides a kind of high strength elastic railway rail plate as shown in Figs. 1-2, including shell 1, described
The top and bottom of shell 1 are equipped with salient point 2, by setting salient point 2, are conducive to prevent backing plate after mounting because train passes through generation
Vibrations the occurrence of backing plate is moved, improves the frictional force of pad surfaces, reduces sidesway, in the shell 1
Portion is equipped with protective device 3, and the protective device 3 includes spiral bar 4, by setting spiral bar 4, is conducive to backing plate in shock absorbing process
In be unlikely to produce deformation so that backing plate maintains certain intensity, improve train by when stability, the spiral bar
4 top and bottom are equipped with pressure block 5, and 3 side of protective device is equipped with the first cavity 6, and the top of the first cavity 6 is equipped with
Second cavity 7.
2 quantity of salient point is arranged to multiple, and the shell 1 is made of elastomeric material, by setting the outer of rubber material
Shell 1, is conducive to backing plate and reaches that wear-resisting, corrosion-resistant, water-fast, oil resistant, heat-resisting, pressure-resistant, impact resistance, elasticity is good, sizing in use
Flexible type and other effects, the pressure block 5 are not made of PVC material afterwards, and first cavity 6 is internally provided with colloid 8, passes through setting
First cavity 6 and colloid 8, are conducive to the heat of the absorption pad intralamellar part of maximum function so that backing plate constant temperature, adds pad
