Abstract
The utility model relates to a non-conventional type steel rail with symmetroid convex ribs on the web of rail. The existing non-conventional type steel rail has the disadvantages of complex processing method and high cost. The purpose of the utility model is realized in such a way that the whole rail is of integration structure which comprises a rail base 1, the web of rail 2, and a rail head 4. The rail base 1 has slope-shaped transition with the web of rail 2, symmetroid convex ribs 3 are arranged on the web of rail 2, and the rail head 4 is the same as the rail head of the ordinary steel rail. The utility model is a non-conventional type steel rail with symmetroid convex ribs on the web of rail, and the performance of the web of rail is obviously improved, wherein, compared with the existing non-conventional type steel rail, the ballistic work of the regional area of the web of rail of the utility model is increased by 1.5 to 1.8 times, yield stress is increased by 15 to 20%, tensile strength is increased by 10 to 15%, and elongation is increased by nearly 10%.
Description
The utility model relates to a kind of transition rail.
Transition rail is an a kind of special-purpose rail of realizing that rail track differing heights rail connects.Adopt the transition rail of conventional method moulding at present, the flange of rail has the domatic transition, and the web of the rail is identical with common rail with tread.Existing this transition rail removes the processing method complexity, and the cost height also needs outside large pressing machine and the roll forging machine, and its performance such as shock resistance, stretch-proof performance and mechanical performance are all desirable not to the utmost.
The purpose of this utility model is to provide a kind of web of the rail to have the transition rail of curved surface convex tendon, this transition rail except that forming method easily, have better mechanical property and mechanical performance than existing transition rail.
The purpose of this utility model is achieved in that whole rail is structure as a whole, rail one end connection place cross sectional shape comprises the flange of rail 1, the web of the rail 2,2 one-tenth domatic transition of tread 4 flanges of rail 1 and the web of the rail, have the convex tendon 3 of band symmetroid on the web of the rail 2, tread 4 is identical with common rail.
Advantage of the present utility model is: it is the compromise rail that a kind of web of the rail has the curved surface convex tendon, web of the rail performance be improved significantly, wherein the ballistic work of web of the rail regional area improves 1.5-1.8 doubly than the ballistic work of existing compromise rail, the yield strength ratio flange of rail improves 15-20%, tensile strength improves 10-15%, and elongation per unit length improves about 10%.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is attached views of accompanying drawing 1.
Embodiment: whole rail is structure as a whole, and the composition of rail one end connection place cross sectional shape comprises: the flange of rail 1, the web of the rail 2, tread 4,2 one-tenth domatic transition of the flange of rail 1 and the web of the rail, and the convex tendon 3 that has the band symmetroid on the web of the rail 2, tread 4 is identical with common rail.
Claims (1)
1, a kind of transition rail of web of the rail band curved surface convex tendon, whole rail is structure as a whole, and comprises the flange of rail [1], the web of the rail [2], tread [4], the flange of rail [1] becomes the domatic transition with the web of the rail [2], it is characterized in that the web of the rail [2] has the curved surface convex tendon [3] of symmetry.
