Abstract

The invention provides a rail connecting device and a long steel rail transport trainset. The rail connecting device comprises a rail connector, a sliding rail joint and a fixed rail joint; the rail connector comprises a connecting beam and a connecting base; the two end faces of the rail connector, the end faces, for contact with the rail connector, of the sliding rail joint, and the end faces, for contact with the rail connector, of the fixed rail joint are all convex cambered surfaces, and the generatrix direction of each cambered surface is the vertical direction; the connecting base is provided with a connecting piece and a first connecting hole; the sliding joint and the fixed rail joint are provided with second connecting holes; the connecting piece goes through the first connecting hole and the second connecting holes to connect the sliding rail joint and the rail connector, and the fixed rail joint and the rail connector, respectively; the first connecting hole or the second connecting hole is a slotted hole, and the length direction of the slotted hole extends horizontally and transversely. Even though the rail connecting device is not demounted after the operations of an operating train are completed, the device does not affect the curved passing of the long steel rail transport trainset.

Description

technical field [0001] The invention relates to the manufacturing technology of railway vehicles, in particular to a rail connection device and a long rail transport vehicle set. Background technique [0002] The long rail transport car set is a special car set for transporting welded long steel rails, which is composed of a variety of special vehicles with different functions and structures. The operation trolley for operations such as shifting rails. There are tracks on different vehicles on the long rail transport vehicle group. The operation trolley moves on the rails. The track connection device is set between the two vehicles to connect the tracks on adjacent vehicles. together to form a unitary device. [0003] The existing rail connection device is composed of a fixed rail joint, a sliding rail joint and a track connecting body. The fixed rail joint and the track are of an integrated structure and are directly welded on the vehicle. The sliding rail joint is fixed o...
