Sealed frame type integrated striker for railway transportation truck

The invention provides a sealed frame type integrated striker for a railway transportation truck. The sealed frame type integrated striker consists of a striker, a wearing plate and a regulating base plate; the striker is formed by integral casting; an opening of the striker is of a trumpet shape; a striker vehicle coupler supporting surface is arranged in the striker; the striker vehicle coupler supporting surface is of an integrated sealed frame type structure; the regulating base plate is arranged on the striker vehicle coupler supporting surface; the regulating base plate is welded on the striker vehicle coupler supporting surface; the wearing plate is positioned above the regulating base plate and is welded with the regulating base plate into one whole body. The sealed frame type integrated striker is suitable for an E/F type vehicle coupler in the AAR (Association of American Railroads) standard, can meet vertical supporting and transfer of a longitudinal force of the vehicle coupler and can implement regulation on the height of the vehicle coupler; meanwhile, by optimal design on the opening of the striker, the angle of the opening of the striker is increased, the swing angle of the vehicle coupler, which is allowed by a vehicle body structure, when the vehicle passes through a small curve and an S-shaped curve is improved and the requirements on operation when the vehicle passes are met.
