Abstract
The utility model discloses a track heavy load base plate, which comprises a plate body, wherein upper reentrant cavities are distributed on the surface of the plate body; and the lower reentrant cavities are arranged on the back of the plate body. The track heavy load base plate is very suitable for tracks.
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 curve rate (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 the surface distributed of said plate body has last cavity, and the back side of plate body is distributed with down cavity.
The utility model has the advantages that: the utility model since plate body be 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 plate body upside of the present invention and downside 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A generalized section of Fig. 1.
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 this plate body is an elastic body.The surface distributed of said plate body 1 has last cavity 3, and the back side of plate body 1 is distributed with down cavity 5.Last cavity 3 is semicircle cavity, and following cavity 5 also is semicircle cavity.
Plate body 1 surface is gone up avris and is respectively plane 2 and plane 4 with following avris, and the last avris at plate body 1 back side and following avris have the plane corresponding with plane 2 and plane 4 respectively.
Claims (4)
1. a rail is used heavily loaded backing plate, comprises plate body, it is characterized in that the surface distributed of said plate body has last cavity, and the back side of plate body is distributed with down cavity.
2. rail according to claim 1 is used heavily loaded backing plate, it is characterized in that avris and following avris are respectively the plane on the plate body surface, the last avris at the plate body back side and following avris have respectively with the plate body surface on avris and the corresponding plane of following side plane.
3. rail according to claim 1 is used heavily loaded backing plate, it is characterized in that cavity is semicircle cavity, and following cavity also is semicircle cavity.
4. rail according to claim 1 is used heavily loaded backing plate, it is characterized in that described plate body is an elastic body.
