Description
Technical field
The present invention relates to a kind of rail lower bolster.
Background technology
Rail lower bolster is arranged between the foot of railroad track and underlying track foundation, and this backing plate has the railroad shoe part for receiving track foot.Railway rail pad is made up of resilient elastomeric materials such as ethylene vinyl acetate copolymers (EVA) usually.In typical railway rail pad, a railroad shoe part wherein interarea or two interareas is provided with multiple projection, as column or rib.The design of this backing plate and this backing plate should be made to have hardness needed for the needs of the railroad track using this backing plate and wearing character for the manufacture of the selection of the material of this backing plate.
Therefore, in the urgent need to a kind of backing plate with the hardness/wearing character of improvement.
Summary of the invention
According to the present invention, provide a kind of rail lower bolster, it is used in the position between the foot of railroad track and underlying track foundation, described backing plate has the railroad shoe part of the foot for receiving railroad track, when described backing plate in use time, two opposite edges of described railroad shoe part are parallel to the longitudinal axis extension of described track, and at least one interarea of described railroad shoe part is provided with multiple projection, wherein, described projection is distributed on described of described railroad shoe part unevenly, make that area that described is occupied by described projection and described do not have the ratio of the area of described projection to be greater than the value of this ratio in the central area of described railroad shoe part in the value of the fringe region of described railroad shoe part, described fringe region is adjacent with edge described in one of them, described central area is adjacent with described fringe region.Described projection may be, such as, and column or rib.The quantity of described projection in described fringe region and central area and position determine hardness and the wearing character of described backing plate.
Described backing plate is designed to make described backing plate may have the hardness reduced relative to traditional backing plate, backing plate wearing and tearing is restricted to acceptable degree simultaneously.
Preferably, described ratio is also greater than the value of this ratio in described central area in the value of another fringe region that is adjacent with edge described in another, described railroad shoe part.
When described projection is column, described column may line up the row being roughly parallel to described opposite edges, each column has roughly the same size, and in described central area, be greater than closer to the column quantity in the row at the center of described railroad shoe part closest to the column quantity in the row of described fringe region.Described bearing also may line up the row being approximately perpendicular to described two opposite edges, wherein, in column that is adjacent with the center of described railroad shoe part but a segment distance of being separated by is capable, the value of the ratio of projection and white space is greater than the value of this ratio in the column farther from described center arranges.
In a preferred embodiment, the area of each described column is identical, and the interval between described column is change.
The first center line of described railroad shoe part that described bearing preferably extends relative to the longitudinal axis being parallel to described track is symmetrical.Advantageously, the second center line of described railroad shoe part of also extending relative to the longitudinal axis perpendicular to described track of described column is symmetrical.

Fig. 1 C is the end-view of the backing plate shown in Figure 1A;
Fig. 1 D is the phantom drawing of the backing plate shown in Figure 1A;
Fig. 2 is the plan view of the backing plate according to the first embodiment of the present invention;
Fig. 3 is the plan view of backing plate according to a second embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1A to 1D, according to a kind of backing plate 1 of the present invention, there are approximate rectangular railroad shoe part 2 and four ear 3a, 3b, 3c and 3d be respectively formed on four angles of railroad shoe part 2.This ear 3a, 3b, 3c and 3d are for being placed on the position relative to pressing plate anchoring shoulder (not shown) in track foundation (not shown) by backing plate 1.When this backing plate is used in the below of track, second edge 2b of the railroad shoe part 2 between the first edge 2a of the railroad shoe part 2 between ear 3a and 3b and ear 3c and 3d is positioned at the position of the longitudinal axis perpendicular to track, and the 4th edge 2d of the railroad shoe part 2 between the 3rd edge 2c of the railroad shoe part 2 between ear 3a and 3c and ear 3b and 3d is positioned at the position of the longitudinal axis being roughly parallel to track (not shown).
Railroad shoe part 2 has two interareas 4A, 4B, and each interarea is formed multiple column 5 roughly with circular cross-section and equivalent size.These columns 5 are distributed on each interarea unevenly, column 5 fit on itself and another interarea is accurate, make that area that the face of railroad shoe part 2 is occupied by column 5 and this face do not have the ratio of the area of column 5 to be greater than the value of this ratio in the central area 7 of railroad shoe part 2 in the value of fringe region 6a, 6b of railroad shoe part 2, fringe region 6a, 6b are adjacent with third and fourth edge 2c, 2d of railroad shoe part 2 respectively, and central area 7 is adjacent with fringe region 6a, 6b.In whole railroad shoe part 2, this ratio reduces gradually from edge 2c, 2d to the center 2e of railroad shoe part 2.
In the present embodiment, by selecting quantity and the position of the column 5 in edge and central area 6a, 6b, 7, required rate value can be obtained, and backing plate characteristic.
Particularly, in backing plate 1, column 5 arranges by the row of edge 2c, 2d of being parallel to railroad shoe part 2.There are 7 row a1 to a7 being parallel to edge 2c, 2d.As shown in Figure 1A, in row a1 and a7, there are 9 columns, in row a2 and a6, have 6 columns, in row a3 and a5, have 4 columns, in row a4, have 4 columns.Therefore, be greater than closer to the column quantity in the row of the center 2e of railroad shoe part 2 near the column quantity in the row of fringe region 6a, 6b in central area 7.
Column in row a1 to a7 is also by the row arrangement being parallel to edge 2a, 2b.There are 9 row b1 to b9.As shown in Figure 1A, in b1 and b9 that be expert at, there are 5 columns, in b2 and b8 that be expert at, have 4 columns, in b3 and b7 that be expert at, have 5 columns, in b4 and b6 that be expert at, have 6 columns, in the b5 that is expert at, have 2 columns.Therefore, in the present embodiment, in but the column at interval adjacent with the center 2e of railroad shoe part 2 is capable, the rate value of projection and white space is greater than the value of this ratio in the column that decentre is farther is capable.
Backing plate 1 always has 42 columns on each 4A and 4B of panel 1.
The pattern of column 5 is symmetrical relative to two centre line C L 1 of railroad shoe part 2, CL2.Row a4 is positioned in centre line C L 1, and row b5 is positioned in centre line C L 2.
In this way, no matter which kind of mode is around on track foundation, as long as ear 3a to 3d is positioned on pressing plate anchoring shoulder, can proper use of backing plate.Backing plate 1 has fixing antelabium 8 along edge 2c between ear 3a and 3c, between ear 3b and 3d, have another fixing antelabium 8 along edge 2d, in order to by this backing plate down by and it is absorbed in track fastening combined piece.If these antelabium 8 are dispensable, and are omitted, so, because the pattern of the column 5 on each interarea 4A, 4B of railroad shoe part is identical, this backing plate can also upwards use by arbitrary face.
Another embodiment of this backing plate has extra column 5 and is placed on, and such as, the a4 row that b2 and b8 is capable, and a3 and the a5 row that b5 is capable, to regulate the hardness needed for this backing plate.Such backing plate as shown in Figure 2.This backing plate has 46 columns altogether.
