Abstract
The utility model discloses a heavy-duty cushion plate for a rail, which comprises a plate body. The plate body comprises an upper elastic body and a lower elastic body, the upper elastic body is arranged on the upper side of the plate body, the lower elastic body is arranged on the lower side of the plate body, and upper concave cavities are distributed on the surface of the upper elastic body. The plate body uses the two elastic bodies with different hardness so that the plate body has a first stiffness value and a second stiffness value. Furthermore, the heavy-duty cushion plate cannot be easily loosened and exposed from the position under the rail.
Description
Technical field
The utility model relates to a kind of rail and uses backing plate, and particularly a kind of rail is used heavily loaded backing plate.
Background technology
Backing plate under the common rail, after load was added to certain value, with having corresponding rigidity value, as continuing the ground loaded load that do not continue, the rigidity value of this backing plate is curve rising at leisure also, skyrocket (fundamental change) can not occur for a moment.And existing rail to a special technical requirement of backing plate exactly after vertical load is added to certain value; Increase load again; The rigidity value of its backing plate need have one and skyrocket (sharply increasing); The slope of curve (climbing speed) that to be rigidity value increase with load is more than at least two times, and existing backing plate can't satisfy this technical requirements.In addition, existing backing plate along with train pass through also climb out of from rail easily.
Summary of the invention
The purpose of the utility model is to develop a kind of rail to use heavily loaded backing plate.
The utility model will solve be existing rail with backing plate its rigidity reach that certain value can't skyrocket suddenly and backing plate along with the easy problem that climbs out of under the rail of passing through of train.
The technical scheme of the utility model is: it comprises plate body, and described plate body comprises elastic body and following elastic body, and last elastic body is located at the upside of plate body, and following elastic body is located at the downside of plate body, and going up elastomeric surface distributed has last cavity.
The utility model has the advantages that: the plate body of the utility model is owing to use two kinds of different hardness elastomer, so after being added to the value of a setting when load, softer last elastic body is crushed; It is first rigidity value that rail is run into the rigidity value that descends elastic body and obtain a correspondence; When load continued to increase, the following elastic body of said backing plate had carried load, but because elastomeric hardness is higher down; So a turning point will appear in rigidity value at this moment; Its rigidity value can sharply rise, and obtains the rigidity value under the corresponding load, i.e. second rigidity value.In addition, because the plate body of the utility model is provided with cavity, so the contact area of rail and backing plate is little, the friction that backing plate receives rail is little, then backing plate train through the time just be not easy under rail, to crawl out.In addition, this backing plate is used at the rail turning, and backing plate is born when keeping low rigidity because of rail the stressed of the backing plate avris that brings of turning; This is because the plate body upside and the downside of the utility model are the plane; The centre is a cavity, so for the backing plate at rail turning, when train passes through; Load mainly is added in the upside or the downside of plate body, and the plane structure of upside or downside can make and bears stressed that rail turns and bring when keeping low rigidity.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in the figure, the utility model comprises plate body 1, and described plate body 1 comprises elastic body 5 and following elastic body 4, and last elastic body 5 is located at the upside of plate body 1, and following elastic body 4 is located at the downside of plate body 1, and the surface distributed of last elastic body 5 has last cavity 6.Last cavity 6 is semicircle cavity.
The surface distributed of following elastic body 4 has following cavity 9, and this time cavity 9 is semicircle cavity.Last elastic body 5 back sides are distributed with and embed post 10, and the following elasticity 4 body back sides are distributed with down embedding post 12; Be provided with embedded hole 11 in the last cavity 6 of last elastic body 5, be provided with down embedded hole 13 in the following cavity 9 of following elastic body 4; The end of last embedding post 10 is embedded in down in the embedded hole 13, and the end of following embedding post 12 embeds goes up in the embedded hole 11.The left side of last elastic body 5 and right side are respectively equipped with button pin 8 and button pin 3.
Plate body 1 surperficial upside and downside are respectively plane 2 and plane 7, and the upside at the plate body back side and downside have to be had respectively and plate body surface upside and the corresponding plane of following side plane.
The hardness of last elastic body 5 less than or greater than the following hardness of elastic body 4.
