Urban rail transit steel rail overhauling and replacing operation train

Abstract

The invention provides an urban rail transit steel rail overhauling and replacing operation train, and belongs to the technical field of rail engineering machinery. Comprising a rail transporting vehicle, a rail welding vehicle, a rail distributing vehicle, a towing vehicle, a transition vehicle, a rail changing vehicle and a rail unloading vehicle; the operation vehicle group is divided into two parts, namely a rail distribution operation vehicle group and a rail changing operation vehicle group; wherein the rail transporting vehicle, the rail welding vehicle and the rail distributing vehicle are combined and connected to form a rail distributing operation vehicle set; the traction vehicle, the rail transporting vehicle, the rail welding vehicle, the rail unloading vehicle, the transition vehicle and the rail changing vehicle are selected, combined and connected into a rail changing operation vehicle set according to the line rail storage conditions. According to the invention, the long steel rail can be welded on the vehicle, one long rail bar can directly fall to the ground by adopting an operation mode of unloading and welding at the same time, the inconvenience of welding the steel rail on a construction site is eliminated, the efficiency of metro rail replacement overhaul construction is improved, the number of personnel and the labor intensity of workers are reduced, and the safety is improved.
