Description
Technical Field
The utility model relates to a little clear distance sleeve rail track rail joint splint device belongs to the railway engineering field.
Background
The central European Banner needs to travel through countries with different track gauges, wherein the most typical situation is that the union republic of the original Soviet Union adopts 1520mm wide track gauge. The rail sleeving is that two lines with different track gauges are collinear, the lines with different track gauges are mutually nested, and a sleeper and a roadbed are shared. The casing rail greatly reduces the project amount, saves the project investment, does not need to build a replacing station or a bogie replacing plant, and can also shorten the goods transportation time.
The traditional rail connection is generally composed of a joint splint (commonly called as a fishtail splint), a joint bolt (commonly called as a fishtail bolt) and the like. On a railway, in order to prevent all fishtail bolts from being cut off by wheels caused by derailing of a train, one end of each fishtail bolt is made into a spherical shape, and a nut is adopted at the other end of each fishtail bolt; at the spherical end, an oblong boss needs to be made at the spherical end for tightening the nut. On the set rail railway track, when two rails of different gauge lines are close to each other, after the joint splint of one rail is installed, the fishtail bolt of the other rail cannot penetrate through the gap between the two rails, so that the installation is difficult.
For this reason, it is very important to develop a new type of joint clamp device suitable for a small clear distance casing rail.
