Abstract
The utility model relates to a steel rail for silencing joints of a railway. The steel rail for silencing joints technically adopts that both ends of a steel rail are respectively rolled into a Z-shaped male joint end and a Z-shaped female joint end, or both ends of the steel rail are respectively rolled into the oblique line male joint end and the oblique line female joint end. When connected, both ends of the steel rail are fixed on a railway sleeper by rivets. The steel rail for silencing joints solves the problems that the existing straight joint of the steel rail of the railway has loud noise and pollutes the surrounding environment of the railway. The utility model can be applied to the railway based on the experiment.
Description
Technical field:
The utility model relates to " rail that a kind of seam of eliminating the noise is used " that a kind of railway is used.
Background technology:
The rail that present railway traffic is used all is that vertical masonry joint connects, and particularly railway interests is again and again with train speed-raising, the rail that this vertical masonry joint connects, when train by the time sound will increase, the resident noise pollution along the line to railway will be bigger, and therefore, eliminating noise is a kind of urgent problem.
The utility model content:
In order to overcome the two ends that have rail now all is vertical cross section, the joint of two one steel rails is straight joints, when train by the time send the sound of click click often, for this reason, the rail that the inventor provides a kind of seam of eliminating the noise to use, better through model testing noise elimination effect, can reduce railway noise pollution along the line.
The technical scheme that its technical problem that solves the utility model adopts is, in the operation of rolling of rail the two ends of rail being rolled into an end respectively is Z-shape steel rail public access seam end, in addition end is for the I shape rail of the female seam end of Z-shape steel rail or the two ends of rail are rolled into an end respectively is bias type rail public access seam end, and end is the I shape rail of the female seam end of bias type rail in addition.
The beneficial effects of the utility model are, in existing steel rail rolling, technology improved a little and can realize rail of the present utility model two ends form, can reduce near the noise pollution the railway, also reduce the vibration of train, can grow distance with rail welding, be convenient to the rail dismounting.
Description of drawings:
Fig. 1 is the utility model side structure schematic diagram.
Fig. 2 is the utility model joint schematic diagram.
Among the figure 1, rail Z type public access seam end, 2, the bull headction top-side, 3, the rail main body, 4, the female seam end of rail Z type, 5, the i iron bottom sides, 6, rail oblique line public access seam end, 7, the female seam end of rail oblique line, 8, the bull headction cross section.
The specific embodiment:
In Fig. 1, the two ends of rail main body 3 are rolled into Z type end respectively, an end is a rail Z type public access seam end 1, and end is the female seam end 4 of rail Z type in addition, and bull headction top-side 2 and i iron bottom side 5 and bull headction cross dimensions still adopt existing rail size; Also the two ends of rail main body 3 can be rolled into the oblique line end respectively, an end is a rail oblique line public access seam end 6, and end is the female seam end 7 of rail oblique line in addition.
In Fig. 2, rail Z type public access seam end 1 and the female seam end of rail Z type 4 usefulness rivets are fixed on the railway sleeper (wood or steel concrete); Rail oblique line public access seam end 6 and the female seam end of rail oblique line 7 usefulness rivets are fixed on the railway sleeper, and existing rail size is still adopted in bull headction cross section 8.
Claims (1)
1, the rail that noise elimination seam is used, it is characterized in that: the two ends of rail main body (3) are rolled into Z type end respectively, one end is a rail Z type public access seam end (1), end is the female seam end (4) of rail Z type in addition, and bull headction top-side (2) and i iron bottom side (5) and bull headction cross dimensions still adopt existing rail size; Also the two ends of rail main body (3) can be rolled into the oblique line end respectively, an end is a rail oblique line public access seam end (6), and end is the female seam end (7) of rail oblique line in addition.
