Abstract
The utility model relates to a railway forge welding frog. A frog center of the railway forge welding frog is welded with the full cross section of a point rail, the frog center and the point rail are welded with wing rails, and the section of the frog center forms a +/-shape. Part rail surfaces of the wing rails are improved, and the railway forge welding frog is through hardening and tempering treatment. The utility model is suitable for ultralong jointless and common line railway switches. The service life of the frog can be improved.
Description
Railway smithwelding railway frog is applicable to and is laid on the track switch that road speed is no more than the seamless and general circuit of transregional overlength of 160km/h that it can be welded into seamless turnout at the scene with the rail that joins.
Railway generally adopts solid manganese steel frog at present, begin to produce from the sixties, use till today always, because there is the internal flaw of casting in solid manganese steel frog, cause it exhausted most damaged before not reaching the limit of wear prerequisite, particularly in the technology of development overlength gapless track, because the railway frog of potassium steel and the rail of high-carbon steel are difficult to be welded to each other, in transregional overlength gapless track, use high manganese steel frog to become technology barrier, promptly allow to overcome this obstacle, also short application life because of high manganese steel frog, should not on transregional overlength gapless track, frequently change use.
The purpose of this utility model provides a kind of smithwelding railway frog, and its forging fork heart and heart rail and wing rail are welded into as a whole, enables to transmit the fixed railway frog of gapless track TEMPERATURE FORCE.
The purpose of this utility model is achieved in that its can be made up of with the forging fork heart of wing rail rail head and flange of rail welding middle manganese or Mn-Cr steel; The full section welding of the fork heart and heart rail, the fork heart, heart rail and wing rail welding; Fork heart cross section is " ± " shape, and the local rail level of wing rail improves; The railway frog modifier treatment; And use and can adorn not detachable connecting bolt, reach the purpose of making the smithwelding railway frog.
Owing to adopt such scheme, average life prolong 0.5-1.5 doubly than high manganese steel frog the application life of smithwelding railway frog.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the plan view of the utility model smithwelding railway frog general assembly.
Fig. 2 is the insight structural map of the fork heart end face of smithwelding railway frog.
Fig. 3 is the fork heart cross section constructional drawing of smithwelding railway frog.
Fig. 4 is two symmetric channel rail cross section constructional drawings of smithwelding railway frog.
The utility model can be made can be measure-alike with existing railway frog, satisfies and exchange the dissimilar rail that require, the smithwelding railway frog of jack per station.Fig. 1 is an example of utility model.The fixed railway frog that is used for No. 12 acclerating road switches of 60kg/m rail, rail level are provided with 1:40 tread slope, and its length is identical with high manganese steel frog, and the nail pitch-row of railway frog backing plate also can keep consistent with wooden switch tie and concrete switch sleeper simultaneously.Details are as follows for its structure: it is by numbering 1,2 wing rails; The numbering 3 fork hearts; Numbering 4,5 heart rails and six roots of sensation connecting bolt, 12 interval iron, 10 backing plates are formed.Be applicable to that being laid on road speed is no more than on the seamless and general circuit track switch of transregional overlength of 160km/h.
Claims (1)
1, a kind of railway smithwelding railway frog by can forming with the forging fork heart of wing rail rail head and flange of rail welding of middle manganese or Mn-Cr steel, is characterized in that: the full section welding of the fork heart and heart rail, and fork heart heart rail and wing rail welding, fork heart cross section is " ± " shape.
