Detailed Description
The invention is further described below with reference to examples and figures:
to facilitate an understanding of the present application, other improvements relating to improvements of the present application (alternative applications) are briefly described first.
As shown in fig. 1-4, the improved track vibration damping and distance adjusting block 101 comprises a vibration damping layer 1 and a pressure fixing layer 2. The side pressure edge of the track vibration-damping distance-adjusting block 101 comprises a vibration-damping layer side pressure sheet 3 of the vibration-damping layer 1 and a fixed-pressure layer side pressure sheet 4 of the fixed-pressure layer 2. The damping layer 1 also has a damping layer upper lamination 5.
The improved track vibration-damping and distance-adjusting block 101 has the function that the vibration-damping layer 1 is tightly pressed on the surface of the rail foot 26 of the steel rail 22, and the function of absorbing energy and damping and preventing rainwater from penetrating between the vibration-damping layer 1 and the surface of the pressed rail foot 26.
The longitudinal length (rail length direction) of the rail vibration damping distance adjusting block 101 is longer than the longitudinal length of the iron pad 24 so as to avoid that rainwater containing conductive substances (scrap iron generated by wheel rail abrasion and the like) flows to the lower part of the rail 22 as much as possible to lead the rail 22 to be communicated with the iron pad 24.
In order to avoid the relative sliding of the vibration reduction layer 1 and the fixed compression layer 2, an inward boss 6 is arranged on the fixed compression layer side compression sheet 4, a vibration reduction layer limiting notch 7 is arranged on the vibration reduction layer side compression sheet 3, and the inward boss 6 is clamped in the vibration reduction layer limiting notch 7.
The term "tight joint" or "tight connection" as used herein is not meant to be a strict air tight seal in a generic sense, but is limited to the prevention of rain water from flowing between the rail 22 and the rail pad 102 as required by the present invention.
As shown in fig. 2, 3, 4, 5, 7 and 8, in the structure that the rail damping distance-adjusting block and the rail lower base plate are closely connected and cover the edges of rail feet, clamping grooves with downward openings are formed in side-pressing edge areas of the rail damping distance-adjusting block 101, side walls corresponding to the clamping grooves are respectively formed on two sides of the rail lower base plate 102, and when the structure is applied, the side walls of the rail lower base plate 102 are inserted into the clamping grooves of the rail damping distance-adjusting block 101, so that the rail lower base plate 102 and the rail damping distance-adjusting block 101 are connected in a sealing mode. In this way, rainwater can be prevented from entering between the rail 22 and the rail pad 102, and the rail 22 and the iron pad 24 can be prevented from being conducted to cause scattered current carried by the rail 22 to flow into the ground.
The clamping groove comprises a clamping groove I9 and a clamping groove II 10, the clamping groove I9 is arranged on the lower end face of the inward boss 6 of the fixed-pressure layer side pressing piece 4 of the side pressure edge, the clamping groove II 10 is arranged at the joint of the vibration-damping layer side pressing piece 3 and the vibration-damping layer upper pressing piece 5 of the track vibration-damping distance-adjusting block 101, and the clamping groove II 10 is provided with two sections which are respectively positioned outside the front side and outside the rear side of the vibration-damping layer limiting notch 7. The side wall comprises a side wall I11 and a side wall II 12; the side wall of the lower rail pad 102 is provided with a pad limiting notch 8, the side wall of the bottom of the pad limiting notch 8 is a side wall I11 corresponding to a clamping groove I9, and the side walls outside the front side and outside the rear side of the pad limiting notch 8 are side walls II 12 corresponding to a clamping groove II 10.
The clamping groove I9 is in a shape of a Chinese character 'ji', two ends of the outer side groove wall are respectively provided with opposite inner blocking surfaces 13, and two ends of the inner side groove wall are respectively provided with a backward outer blocking surface 14; the side wall I11 is in a shape of a Chinese character 'ji' and corresponds to the clamping groove I9, the two ends of the inner side of the side wall I11 are respectively provided with an inner limit surface 15, and the two ends of the outer side of the side wall I11 are respectively provided with an outer limit surface 16 which can be attached to the inner baffle surface 13; when the track vibration reduction and distance adjustment block 101 is closely connected with the track lower base plate 102, the first side wall 11 is inserted into the clamping groove 9, the inner limit surface 15 on the inner side of the first side wall 11 is attached to the outer limit surface 14, and the outer limit surface 16 on the outer side of the first side wall 11 is attached to the inner limit surface 13. In this way, not only is the close contact between the track vibration reduction and distance adjustment block 101 and the track lower base plate 102 realized in the area, but also the relative limit between the track vibration reduction and distance adjustment block 101 and the track lower base plate 102 is realized.
As shown in fig. 2 and 3, the inward boss 6 has a convex layer 17 protruding from the vibration damping layer side sheet 3, and the inner groove wall is provided on the convex layer 17. This arrangement is equivalent to increasing the thickness of the inward boss 6, which increases the structural strength of the arrangement region of the first clamping groove 9.
When the track vibration reduction and distance adjustment block 101 is closely connected with the track lower base plate 102, the protruding layer 17 is positioned in the base plate limiting notch 8. The rail pad 102 is bonded smoothly to the convex layer 17 of the vibration damping layer side pressure sheet 3.
As shown in fig. 5 and 6, the first side wall 11 in a shape of a Chinese character 'ji' is composed of a top plate 18 and wing plates 19 at two ends, wherein the wing plates 19 at two ends extend towards each other respectively for the second side wall 12 in front of the first side wall 11 and the second side wall 12 behind the first side wall 11, two ends of the top plate 18 are integrally connected with the end parts of the wing plates 19 at two ends respectively in an overlapped state, and the top plate 18 protrudes outwards relative to the whole of the second side wall 12. The arrangement is such that the damping layer side press sheet 3, the fixing layer side press sheet 4 and the rail lower pad 102 are smoothly connected in a snap-fit manner.
The second side wall 12 is provided with a reverse folded edge 20 which is folded inwards and used for buckling the edge of the rail foot 26, and when the rail vibration reduction distance adjusting block 101 is closely connected with the rail lower base plate 102, the reverse 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 reverse folded edge 20 and the bottom of the clamping groove two 10, so that a support is avoided between the side wall two 12 and the track vibration reduction and distance adjustment block 101, and the acting force of the elastic strip pressing down the track vibration reduction and distance adjustment block 101 is reduced.
The above embodiments are only for the purpose of more clearly describing the present invention and should not be construed as limiting the scope of the present invention, and any equivalent modifications should be construed as falling within the scope of the present invention.
