Abstract
The utility model discloses a kind of Rubber sleeper pad, especially a kind of Rubber sleeper pad that can be used for railway construction, belong to railway installation apparatus technical field.It comprises the sleeper pad body of the rectangular plate-like structure that rubber is made, and described sleeper pad body offers and extends elongated slot along rail length direction, be filled with sizing material particle in described elongated slot.The utility model in use; sleeper pad pad is made sleeper pad body offer one of elongated slot to face down below rail; due to filler gum particle in elongated slot; sleeper spacer is so not only made to have certain rigidity; train is when steel lotus changes, and because sizing material particle can be compressed or expand, the impact that sleeper pad body receives is little; therefore the vibration frequency fluctuation range of sleeper pad can not be very large, and compared with prior art effectiveness in vibration suppression improves greatly.
Description
Technical field
The utility model relates to a kind of Rubber sleeper pad that can be used for railway construction, belongs to railway installation apparatus technical field.
Background technology
The rail that general railway is laid about just has a thermal expansion seam every 20 meters, this thermal expansion seam will cause the vibration of the noisy sound of the hard hit in train driving process and train, and accelerate the abrasion of wheel and rail contact terminal, shorten the application life of locomotive; Noisy sound and train vibration also affect the comfort level that passenger takes simultaneously.If welded by these dilatation joints and polish, and below rail, be lined with soft sleeper pad, the vibration of noisy sound and train so just can be made greatly to alleviate.Just become bent when rail expands downwards a little, because be lined with sleeper pad, can distortion be produced.The position of rail underlay rail bolster has the heavy burden of cement sleeper to be pulled down by rail, limits the direction of deformation of rail.This sleeper pad of prior art is generally the rectangular flat shape structure adopting elastomeric material to make.Because the surface ratio of this sleeper pad is more smooth, when train steel lotus changes, the vibration frequency of sleeper pad also can change thereupon, and therefore the effectiveness in vibration suppression of this sleeper pad is poor.
Summary of the invention
The purpose of this utility model is the sleeper pad providing a kind of vibration frequency fluctuation range little, to solve the technical problem of the sleeper pad effectiveness in vibration suppression difference of prior art.
The utility model adopts following technical scheme: a kind of Rubber sleeper pad, comprises the sleeper pad body of the rectangular plate-like structure that rubber is made, and described sleeper pad body offers and extends elongated slot along rail length direction, be filled with sizing material particle in described elongated slot.
The shape of the cross section of described elongated slot is arc or V-arrangement or U-shaped.
Described elongated slot has 3 at least.
Described sizing material particle is made up of butadiene-styrene rubber or chlorobenzene rubber.
In described sleeper pad body, the content of rubber is 55%.
The beneficial effects of the utility model are: the utility model in use; sleeper pad pad is made sleeper pad body offer one of elongated slot to face down below rail; due to filler gum particle in elongated slot; sleeper spacer is so not only made to have certain rigidity; train is when steel lotus changes, and because sizing material particle can be compressed or expand, the impact that sleeper pad body receives is little; therefore the vibration frequency fluctuation range of sleeper pad can not be very large, and compared with prior art effectiveness in vibration suppression improves greatly.
Further, butadiene-styrene rubber or chlorobenzene rubber are made sizing material particle and are had good elasticity and ageing resistance, are highly suitable for railway and lay.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of embodiment of the utility model as shown in Figure 1 to Figure 2, the Rubber sleeper pad of the present embodiment comprises the sleeper pad body 1 that elastomeric material is made, sleeper pad body 1 offers four and extend elongated slot along rail length direction, the shape of the cross section of elongated slot is arc, is filled with the sizing material particle 2 that butadiene-styrene rubber is made in elongated slot.
The raw material of sleeper pad body 1 is synthetic rubber, adopts butadiene-styrene rubber in conjunction with sulfurless curing system; Select heat-resisting age resistor.Rubber is selected based on this rubber of fourth, neoprene, and the content of rubber is about 55%.
Sleeper pad pad in use, makes sleeper pad body 1 offer one of elongated slot to face down, undertaken installing and fixing by bolt by the present embodiment below rail.Due to filler gum particle 2 in elongated slot; sleeper spacer is so not only made to have certain rigidity; train is when steel lotus changes; because sizing material particle can be compressed or expand; the impact that sleeper pad body receives is little; therefore the vibration frequency fluctuation range of sleeper pad can not be very large, and compared with prior art effectiveness in vibration suppression improves greatly.
In other embodiment of the present utility model, the quantity of the elongated slot on sleeper pad body can be arranged as required, and elongated slot can be two and plural any amount; The shape of the cross section of the elongated slot on sleeper pad body can also be square or V-arrangement or U-shaped.
In other embodiment of the present utility model, sizing material particle can also be made up of chlorobenzene rubber material.
In other embodiment of the present utility model, the sleeper pad body of suitable rubbers content can be selected as required.
Claims (4)
1. a Rubber sleeper pad, comprises the sleeper pad body of the rectangular plate-like structure that rubber is made, it is characterized in that: described sleeper pad body offers and extends elongated slot along rail length direction, be filled with sizing material particle in described elongated slot.
