The utility model discloses a gantry crane component applied to a high-speed railway, which comprises a crane main body, the top end of the crane main body is connected with a control box in a sliding manner, two sides of the inner wall of the control box are connected with a rotating shaft in a rotating manner, the surface of the rotating shaft is sleeved and connected with two winding wheels, and the surfaces of the two winding wheels are respectively wound and connected with a steel wire rope. The tooth block is pushed to move through the electric push rod installed in the U-shaped block, so that the tooth block is meshed with the corresponding driving gear and the corresponding driven gear, rotation of the rotating shaft is effectively avoided through embedding of the tooth block when the assumed bridge of a railway reaches a certain height, stability of the bridge in the moving process is guaranteed, and the service life of the bridge is prolonged. And through the buffer springs installed at the top ends
