Technical Field
The invention belongs to the technical field of vehicles, and particularly relates to a highway-railway conversion device for a highway-railway dual-purpose vehicle.
Background
The utility model relates to a rail-road vehicle, which is a special device that can not only be used for traction shunting on a track, but also be used for running on a road. With the development of rail transit, the combined car for highway and railway is widely used.
When a road-railway convertible vehicle carries out lane change conversion between a road and a railway, two lane change conversion modes are available at present, one mode is to back the vehicle at the front and the back of a level crossing so that a rear guide wheel is aligned and then descends, the guide wheel continues to back the vehicle, finally, the center of the whole vehicle is coincided with the center of the railway, and then the front guide wheel descends, so that the lane change conversion between the road and the railway is achieved, the scheme is long in time consumption, high in operation difficulty and complex in operation, and potential safety hazards exist at the same time; the other mode is that the road-rail dual-purpose vehicle is driven to a road junction, the lifting oil cylinder is used for driving the inner and outer upright posts to extend, the whole vehicle is controlled to rotate to a proper angle through the rotating mechanism after being lifted, the oil cylinder is contracted to reduce the height of the whole vehicle, and the lane changing operation is completed after the whole vehicle is aligned.
