[0002] At present, large and medium-sized cities at home and abroad are rapidly carrying out the infrastructure construction of subway lines, and the number of rails required has increased dramatically, resulting in an increase in the workload of loading, transporting and unloading rails. For the transportation of medium and long rails with a length of less than or equal to 18m from the material storage site to the construction line, gantry cranes or truck cranes are mainly used for loading or unloading, and railway flat cars are used for transportation. In this way, lifting and loading tools are required at the loading site of the rails, resulting in a sharp increase in basic costs; ordinary railway flat cars are only responsible for transportation, and there are no rail fixing and limiting equipment on the vehicles. The loading is messy and the single vehicle has a small carrying capacity. There are also many safety hazards in the specific transportation process. In addition, the existing rail transport vehicles have the following disadvantages: ① Rail transportation The transport vehicles are basically customized extra-long rail transport vehicles, which are only used for transport vehicles, mainly for track laying on new lines, and cannot lift the entire rail; ② The rail clamping devices of existing rail transport vehicles are basically fixed, and their support frames are also standardized and cannot be disassembled, and are not suitable for transporting other materials; ③ Most of the small vehicle cranes for existing rail transportation are internal combustion, with high energy consumption, high pollution, and poor environmental protection; ④ Most domestic flatbed vehicles carry a crane, and the rails are easy to tilt when lifting the rails, posing a safety hazard; In view of the above points, it is necessary to make improvements.
