Abstract
This application provides a rail welding vehicle, including: a frame; a tracked traveling device disposed below the frame; the tracked traveling device is connected to the frame via a slewing device, and the tracked traveling device and the frame can rotate horizontally relative to each other; a steel wheel traveling device, which is vertically and flexibly disposed below the frame; auxiliary support devices; auxiliary support devices are respectively provided on both sides of the frame, each auxiliary support device including a longitudinal sliding sleeve and auxiliary outriggers respectively disposed at both ends of the longitudinal sliding sleeve, the auxiliary outriggers being longitudinally retractable within the longitudinal sliding sleeve; a welding machine disposed above the frame; and a crane disposed above the frame for lifting the welding machine. In the rail welding vehicle provided in this application, when the auxiliary traveling devices at both ends are supported on the ground, the tracked traveling device can also rotate relative to the frame, allowing it to travel across the rail line via the tracked traveling device, quickly reaching the adjacent welding location, and improving work efficiency.
