Distances among the bottom face long grooves of the bottom face are equal to those among the top face long grooves of the top face. The bottom face long grooves are respectively arranged in the middle of two top face long grooves, arranged on an opposite face of the bottom face, and evenly arranged in an interlacing mode. The multiple bottom face long grooves and the multiple top face long grooves are additionally arranged on the bottom face and the top face of the base plate body so as to reduce noise produced in traveling of a train and a rail. Meanwhile, design of the protruded strips can prolong service life, provides convenience for installation, and has a certain heat dissipation effect.
Description
Technical field
The utility model relates to a kind of thermoplasticity rail backing plate, belongs to the railway rubber materials, is mainly used in the track (sleeper) of railway, the vibration and the noise that produce when being used for weakening vehicle and advancing.
Background technology
In the track (sleeper) of railway, vibrationproof parts such as the vibration that produces when being used for weakening vehicle and advancing and noise, employing be pallet for railway.This pallet for railway comprises the railway rail pad that inserts between rail and the sleeper, is laid on the plate lower bolster under the sleeper, is laid on the track plate vibrationproof part etc. under the slab track.The constituent material of this pallet for railway not only requires: (1) is fit to the low spring constant of service condition; (2) show good vibrationproof performance and shock-absorbing capacity requirement, but also require good compression characteristic (particularly little remaining distortion, low hysteresis loss); (3) high mechanical properties; (4) good resilience; (5) good fatigue durability; (6) Kuan Guang serviceability temperature.Up to now, what be used for that the material of pallet for railway uses is rubber, however rubber pallet for railway processed, especially spring constant is low, and the rubber of quality softness pallet for railway processed is not the goods that possess sufficient durability.And be to reduce spring constant, when rubber was implemented groove processing etc. and constituted pallet for railway, it was inhomogeneous to cause the load of this pallet for railway to disperse, and the groove of concentrating at stress produces be full of cracks etc., causes durability further to reduce; Because the intrinsic shortcoming of elastomeric material, bigger as the energy storage of compressive deformation process, make backing plate self give birth to heat, thereby it is aging to accelerate it, user's life is shorter: the resilience of rubber mat plate is under the effect of compressive stress, namely in the course of the work, increase in time and reducing gradually, the speed that rebound degree reduces increases in time and increases.
The utility model content
The purpose of this utility model is in order to solve the existing defective of rail rubber in the prior art, provides that a kind of cost is low, simple in structure, the thermoplasticity rail backing plate of long service life, good damping effect.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of thermoplasticity rail backing plate, comprise the backing plate body, the bottom surface of described backing plate body and end face respectively are provided with many bottom surface elongated slots and many end face elongated slots, and the two ends in the bottom surface of backing plate body respectively are provided with a raised line, described elongated slot is evenly distributed on bottom surface and the end face of backing plate body respectively, distance between the distance between the elongated slot of described bottom surface and end face elongated slot equates, and described bottom surface elongated slot is on the opposite face of bottom surface in the middle of placing two end face elongated slots respectively, makes its staggered evenly arranging.
In above-mentioned a kind of thermoplasticity rail backing plate, the cross section of described backing plate body is parallelogram, and described raised line places the edge of the last parallel lines of backing plate body.
In above-mentioned a kind of thermoplasticity rail backing plate, described bottom surface elongated slot is identical with the cross section of end face elongated slot, and its cross section is circular arc.
In above-mentioned a kind of thermoplasticity rail backing plate, the ratio of described backing plate body thickness and the groove depth of bottom surface elongated slot on the backing plate body is 3.8-5.3.
In above-mentioned a kind of thermoplasticity rail backing plate, the ratio of described backing plate body thickness and the groove depth of bottom surface elongated slot on the backing plate body is 5.8-7.3.
In above-mentioned a kind of thermoplasticity rail backing plate, the material of described backing plate body is thermoplastic polyester elastomer.
In above-mentioned a kind of thermoplasticity rail backing plate, the ratio of the thickness of the thickness of described raised line and backing plate body is 0.8-1.3.
The beneficial effect that the utlity model has: by respectively increasing many elongated slots at backing plate end face and bottom surface, reduce the noise that train vibration influence produces with rail under steam, simultaneously, its raised line design can improve application life, for its installation provides convenience, can also play certain radiating effect.
