Abstract
The utility model relates to a seamless butt-joint overspeed vibration-free steady steel rail, the two ends of which are provided with joints. The utility model makes the vibration of the running of a train is smaller, and the speed of the train is higher, which brings a great economic benefit to the railway department and the national transportation enterprise.
Description
The utility model relates to a kind of seamless involutory hypervelocity does not have the steady rail that shakes, and mainly makes the rail of train and city railroad vehicle.
The rail connection of prior art is flat mouthful of butt joint, thereby has rail gap, even adopt long rail, also can only reduce the rail gap number.Its weak point is: the train running vibration is bigger; Train running speed is slower; The benefit of railway transportation is lower.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides that a kind of operational shock is little, the speed of a motor vehicle can improve and bring the seamless involutory hypervelocity of great economic benefit not have the steady rail that shakes to country's (containing railway department).
The purpose of this utility model can reach by following measure: rail of the present utility model two ends are for taking mouth.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the figure of the utility model two rails lap-joint;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the profile of rail.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 and Fig. 2 represent structure of the present utility model.Shape, specification and the structure of rail rail body are identical with the prior art (see figure 3), and the rail height represents that with H the flange of rail is wide to be represented with B, and rail head is wide to be represented with b, and the web of the rail is thick to be represented with t.The two ends of existing rail are flush end, and the two ends of the utility model rail are for taking mouth 1, and must satisfy two requirements down during installation: the rail gap of interface size L and prior art is identical; Must reserve overlap joint size a, to satisfy the strength and stiffness requirement of overlap joint mouth.Two overlap joint rail 2 and 3, the flange of rail of rail 2 end faces is wide, rail head is wide and the web of the rail is thick all cuts half, and cutting length is L+a.The flange of rail of rail 3 end faces is wide, rail head is wide and the web of the rail is thick all cuts second half, and cutting length is L+a.
The utility model contrast prior art has following advantage:
Because the rail joint is seamless, thereby the vibration of train running is littler; Train speed is very fast; Give railway department Bring huge economic benefit with the transport undertaking of country.
