Abstract
The utility model belongs to railway installation apparatus technical field, discloses a kind of Novel sleeper pad, is provided with rail cushion body, the evenly distributed equal-sized holdfast of several columns volume of the surface longitudinal of the rail cushion body.The Novel sleeper pad makes sleeper pad closely be connect with concrete, can solve the current caducous shortcoming of sleeper pad, increase embedment strength, be not easily disconnected from sleeper organic composite one, reach wear-resistant, extend maintenance period.The slope mill phenomenon of track is reduced, noise is reduced, improves the stability of operation, railway roadbed is made to keep full and is tamped.
Description
Technical field
The utility model belongs to railway installation apparatus technical field more particularly to a kind of Novel sleeper pad.
Background technology
At present, in China express railway and Line for Passenger Transportation transport routes, railroad track generally uses concrete sleeper.Coagulation
Native sleeper has substantially met the needs of traffic condition, but from the point of view of use condition, also there is the followings for concrete sleeper
Deficiency：
1. in long-term high-speed railway and Line for Passenger Transportation, railway concrete sleeper due to being impacted for a long time by heavy load,
And the influence of many factors such as environmental change, the sleeper pad for being placed in concrete base easily comes off, so as to exacerbate sleeper
Slope mill phenomenon, improve maintenance cost.
2. in the manufacturing process of concrete sleeper, because vibrations generate gas when sleeper pad is connect with concrete, there are rails
Between bolster and concrete, make the two that cannot closely connect, so as to reduce the fatigue resistance of sleeper, shorten using the longevity
Life.
In conclusion problem of the existing technology is：1. sleeper pad easily comes off, the slope mill phenomenon of sleeper is exacerbated,
Improve maintenance cost；2. connecting not close between concrete and sleeper pad, the fatigue resistance of sleeper is reduced, shortening makes
Use the service life.
This sleeper pad country is existing without similar identical product, and the utility model fills up the domestic series of products blank.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of Novel sleeper pad.
The utility model is realized in this way a kind of Novel sleeper pad is provided with rail cushion body, the rail cushion body
The evenly distributed several columns volume equal-sized holdfast of surface longitudinal.Holdfast is effectively embedded into sleeper cement protective layer, is made
Combine closely integral, will not fall off.
Further, the holdfast is two sharp ship anchor-shaped bulge-structures.
Further, the spacing of the holdfast be 35mm, holdfast level interval be 35mm, holdfast width be 7mm, the length of holdfast
It spends for 12mm.
The advantages of the utility model and good effect are：The utility model makes sleeper pad closely be connect with concrete, can
Solve the current caducous shortcoming of sleeper pad, increase embedment strength, be not easily disconnected from sleeper organic composite one, reach anti-
Mill extends maintenance period.The slope mill phenomenon of track is reduced, noise is reduced, improves the stability of operation, makes railway roadbed holding full simultaneously
It is tamped.By experiment, the railway ballast that the sleeper equipped with the sleeper pad can reduce nearly 1/3 is laid with, when extending railway ballast tamping cycle
Between one times or more.It is more than half, 30 decibels of lower noise or more that the crushing phenomenon of railway ballast, which reduces, and the slope mill for effectively reducing rail is existing
As etc..

Fig. 3 is the longitudinal sectional view for the Novel sleeper pad that the utility model embodiment provides；
In figure：1st, rail cushion body；2nd, holdfast.
Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail with reference to Fig. 1 to Fig. 3.
The Novel sleeper pad that the utility model embodiment provides is provided with rail cushion body 1, the table of the rail cushion body 1
The longitudinally evenly distributed several columns volume equal-sized holdfast 2 in face.
As the preferred embodiment of the utility model, the holdfast 2 is two sharp ship anchor-shaped bulge-structures.
As the preferred embodiment of the utility model, the spacing of the holdfast 2 is 35mm, and 2 level interval of holdfast is 35mm,
2 width of holdfast is 7mm, and the length of holdfast 2 is 12mm.
The operation principle of the utility model is：Evenly distributed holdfast 2 is increased when manufacturing between concrete
Contact area, sleeper pad is made closely to link together with concrete；When manufacturing, connect between sleeper pad and concrete
Railway roadbed is made to keep full due to vibrations when connecing and tamped.
The above is only the preferred embodiment to the utility model, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, belongs in the range of technical solutions of the utility model.
