Abstract
The utility model relates to a heat dissipation noise reduction base plate, and belongs to the field of railway rubber. The heat dissipation noise reduction base plate comprises a base plate body. The bottom face and the top face of the base plate body are respectively provided with a plurality of long-strip-shaped grooves. The grooves are evenly distributed in the bottom face and the top face of the base plate body. The distance between two adjacent grooves in the bottom face is equal to the distance between two adjacent grooves in the top face. Heat dissipation holes penetrating through the top face and the bottom face of the base plate body are formed in the base plate body. The heat dissipation holes are evenly distributed in the top face of the base plate body. Noise generated by a train and rails during traveling is reduced through the fact that the top face and the bottom face of the base plate body are respectively provided with the plurality of grooves, meanwhile heat dissipation is effectively and timely carried out on the base plate body through the heat dissipation holes in the top face of the base plate body, so that losses of the base plate body can be reduced, the service life of the base plate body can be prolonged, and a heat dissipation effect of materials is maximally used through ratios of the heat dissipation holes to the thickness of the base plate body.
Description
Technical field
The utility model relates to a kind of heat radiation noise reduction 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 heat radiation noise reduction backing plate of good heat dissipation effect, long service life.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of heat radiation noise reduction backing plate, comprise the backing plate body, the bottom surface of described backing plate body and end face respectively are provided with many grooves that are strip, and described groove is not evenly distributed on bottom surface and the end face of backing plate body, distance between the distance between the groove of described bottom surface and end face groove equates, the backing plate body is provided with the heat elimination hole that runs through its end face and bottom surface, and described heat elimination hole evenly is arranged in the end face of backing plate body.
In above-mentioned a kind of heat radiation noise reduction backing plate, described bottom recesses is on the opposite face of bottom surface in the middle of placing two end face grooves respectively, makes its staggered evenly arranging.
In above-mentioned a kind of heat radiation noise reduction backing plate, described backing plate body is cuboid, and described heat elimination hole quantity is four, linearly is arranged in the centerline of backing plate body, or is arranged in the place, four diagonal angles of backing plate body.
In above-mentioned a kind of heat radiation noise reduction backing plate, described bottom recesses is identical with the cross section of end face groove, and its cross section is circular arc.
In above-mentioned a kind of heat radiation noise reduction backing plate, the ratio of described heat elimination hole maximum size and backing plate body thickness is 2.2-2.8.
In above-mentioned a kind of heat radiation noise reduction backing plate, the material of described backing plate body is thermoplastic polyester elastomer.
In above-mentioned a kind of heat radiation noise reduction backing plate, described heat elimination hole is manhole or square through hole.
The beneficial effect that the utlity model has: by respectively increasing many grooves at backing plate end face and bottom surface, reduce the noise that train vibration influence produces with rail under steam, simultaneously, come timely and effectively the backing plate body to be dispelled the heat by top heat elimination hole, so just can reduce the loss of backing plate body, improve application life, and come the maximum radiating effect that utilizes material for the ratio of its heat elimination hole and thickness.
