Abstract
A steel rail with a rail crown belongs to the field of railways, and mainly solves the problems of abrasion and maintenance of a rail. The technical scheme is as follows: a part of the existing steel rail head is cut, then a layer of rail crown is covered correspondingly, and the rail crown is fixed on the rail head by bolts. The whole steel rail and the existing steel rail can be exchanged with each other for use due to the structure size. The steel rail has the advantages of convenient replacement after the rail crown is abraded, and saved cost.
Description
Technical field
The utility model relates to a kind of rail.
Background technology
Common rail is made of rail head, the web of the rail, the flange of rail, and its cross section is an one.After its rail head experience wear, need to change whole rail.The test rail that is particularly useful for setovering, the part of use or wearing and tearing rail, integral replacing more causes waste.
Summary of the invention
The purpose of this utility model designs a kind of removable rail head structure.
Technical scheme is: machine away a part on existing rail head of rail, cover the corresponding rail hat of one deck then, the rail hat is by being bolted on the rail head, and the rail hat can be dismantled and change.The whole rail that rail hat, rail head, the web of the rail, the flange of rail constitute, its physical dimension and correlation technique parameter all satisfy relevant criterion.
Advantage: after the wearing and tearing of rail hat, be convenient for changing, save cost.
Description of drawings
Accompanying drawing is a cross sectional representation of the present utility model, among the figure: the 1-wheel, the 2-bolt, 3-rail hat, the 4-rail head, the 5-web of the rail, the 6-flange of rail, 7-detect uses linear transducer array.The rail hat can be dismantled and be changed by being bolted on the rail head.
The specific embodiment:
Adopt existing standard rail, on rail head, machine away a part, generally be cut to the maximum planes layer.Then, by mould, roll out the rail hat of corresponding size, the rail hat is by being bolted on the rail head, the whole rail that rail hat, rail head, the web of the rail, the flange of rail constitute, and its physical dimension and correlation technique parameter all satisfy relevant criterion.Because the rail hat at aspects such as abrasion resistancies, can carry out modification through special processing targetedly.The rail hat can be dismantled and change, and makes things convenient for later maintenance.Be particularly useful for the offset test tracks, track length is shorter, safeguards more convenient.
Claims (2)
1. the rail of band rail hat is made of rail head, the web of the rail, the flange of rail, it is characterized in that: covered one deck rail hat on rail head.
2. according to claim 1 with the rail of rail hat, it is characterized in that: rail is preced with by being bolted on the rail head.
