Detailed Description
The invention is further described with reference to the following examples and figures:
to facilitate an understanding of the present application, further improvements (copending applications) related to the improvements of the present application will first be briefly described.
As shown in fig. 1-4, the improved track vibration damping and distance adjusting block 101 comprises a vibration damping layer 1 and a solid pressing layer 2. The lateral pressure side of the track vibration damping and distance adjusting block 101 comprises a vibration damping layer lateral pressing sheet 3 of the vibration damping layer 1 and a pressure fixing layer lateral pressing sheet 4 of the pressure fixing layer 2. The damping layer 1 also has a damping layer upper preform 5.
The improved track vibration-damping distance-adjusting block 101 has the vibration-damping layer 1 tightly attached to the rail foot 26 surface of the steel rail 22, and has the functions of absorbing energy and damping vibration and preventing rainwater from permeating between the vibration-damping layer 1 and the attached rail foot 26 surface.
The longitudinal length (rail length direction) of the rail vibration-damping distance-adjusting block 101 is greater than the longitudinal length of the iron backing plate 24, so as to avoid rainwater containing conductive substances (scrap iron and the like generated by wheel rail abrasion) flowing to the bottom of the steel rail 22 to conduct the steel rail 22 and the iron backing plate 24.
In order to avoid relative slippage between the damping layer 1 and the solid pressing layer 2, an inward boss 6 is arranged on the solid pressing layer side pressing sheet 4, a damping layer limiting notch 7 is arranged on the damping layer side pressing sheet 3, and the inward boss 6 is clamped in the damping layer limiting notch 7.
The term "close fit" or "hermetic connection" as used herein is not meant to be strictly airtight in the general sense, but is limited to the ability to prevent rain from flowing between the rail 22 and the under-rail pad 102 as required by the present invention.
As shown in fig. 2, 3, 4, 5, 7, and 8, in a structure in which a track damping and distance adjusting block and a track bottom shim plate are closely connected to cover the edge of a rail foot, a clamping groove with a downward opening is arranged in a side pressure edge area of the track damping and distance adjusting block 101, side walls corresponding to the clamping groove are respectively arranged on two sides of the track bottom shim plate 102, and when the structure is applied, the side walls of the track bottom shim plate 102 are inserted into the clamping groove of the track damping and distance adjusting block 101, so that the track bottom shim plate 102 and the track damping and distance adjusting block 101 are closely connected. Thus, rainwater does not enter between the rail 22 and the rail pad 102, and the conduction between the rail 22 and the iron pad 24 is prevented, so that stray current carried by the rail 22 can be prevented from flowing into the ground.
The clamping groove comprises a first clamping groove 9 and a second clamping groove 10, the first clamping groove 9 is arranged on the lower end face of an inward boss 6 of a fixed pressing layer side pressing sheet 4 of a side pressing edge, the second clamping groove 10 is arranged at the joint of a damping layer side pressing sheet 3 of the track damping distance adjusting block 101 and a damping layer upper pressing sheet 5, and the second clamping groove 10 is provided with two sections which are respectively positioned outside the front side and the rear side of a damping layer limiting notch 7. The side walls comprise a first side wall 11 and a second side wall 12; and a base plate limiting notch 8 is arranged on the side wall of the under-rail base plate 102, the side wall of the bottom of the base plate limiting notch 8 is a first side wall 11 corresponding to the first clamping groove 9, and the side walls outside the front side and the rear side of the base plate limiting notch 8 are second side walls 12 corresponding to the second clamping grooves 10.
The first clamping groove 9 is shaped like a Chinese character 'ji', two ends of the outer side groove wall are respectively provided with an inner blocking surface 13 which is opposite to each other, and two ends of the inner side groove wall are respectively provided with an outer blocking surface 14 which faces back; the side wall I11 is in a shape of a Chinese character 'ji' and corresponds to the clamping groove I9, inner limiting surfaces 15 are respectively arranged at two ends of the inner side of the side wall I11, and outer limiting surfaces 16 which can be attached to the inner blocking surfaces 13 are respectively arranged at two ends of the outer side of the side wall I11; when the track vibration-damping distance-adjusting block 101 is tightly connected with the lower track pad 102, the first side wall 11 is inserted into the first clamping groove 9, the inner limiting surface 15 on the inner side of the first side wall 11 is attached to the outer blocking surface 14, and the outer limiting surface 16 on the outer side of the first side wall 11 is attached to the inner blocking surface 13. In this way, not only the close contact between the track vibration damping and distance adjusting block 101 and the under-rail pad 102 in the region is realized, but also the relative limit between the track vibration damping and distance adjusting block 101 and the under-rail pad 102 is realized.
As shown in fig. 2 and 3, the inward boss 6 has a projecting layer 17 projecting from the damper layer side laminated sheet 3, and the inner groove wall is provided on the projecting layer 17. The thickness of the inward boss 6 is increased by the arrangement, and the structural strength of the arrangement area of the first clamping groove 9 is also increased.
When the track vibration-damping distance-adjusting block 101 is closely connected with the under-track pad 102, the convex layer 17 is positioned in the pad limiting notch 8. The rail lower backing plate 102 is smoothly combined with the convex layer 17 of the vibration damping layer side pressing sheet 3.
As shown in fig. 5 and 6, the first zigzag-shaped side wall 11 is composed of a top plate 18 and wing plates 19 at two ends, the wing plates 19 at two ends are respectively opposite to the second side wall 12 in front of the first zigzag-shaped side wall 11 and the second side wall 12 behind the first zigzag-shaped side wall 11, two ends of the top plate 18 are respectively connected with the end parts of the wing plates 19 at two ends in an overlapped state, and the top plate 18 is integrally protruded outwards relative to the second side wall 12. The arrangement enables the damping layer side pressing sheet 3 and the pressure fixing layer side pressing sheet 4 to be smoothly connected with the rail lower backing plate 102 in a buckling mode.
The second side wall 12 is provided with a folded edge 20 which is folded inwards and used for buckling the edge of the rail foot 26, and when the rail vibration damping distance adjusting block 101 is tightly connected with the rail lower backing plate 102, the folded edge 20 is positioned in the second clamping groove 10.
As shown in fig. 1, a gap 21 is formed between the top surface of the folded edge 20 and the bottom of the slot two 10, so that the support between the side wall two 12 and the track damping distance adjusting block 101 is avoided, and the acting force of the elastic strip pressing down the track damping distance adjusting block 101 is reduced.
The above-described embodiments are intended to illustrate the invention more clearly and should not be construed as limiting the scope of the invention covered thereby, any modification of the equivalent should be considered as falling within the scope of the invention covered thereby.
