When various tracked vehicles and wheeled vehicles are transported by a railway universal flat car, the tracked vehicles and wheeled vehicles are reinforced by adopting a binding and reinforcing mode of steel wire rope pulling and combined nailing and fixing wooden masking blocks, square timber (triangular blocks) are used for masking and fastening the front and the back of each tracked (tire) of each vehicle, and a cramp is used for nailing the square timber (triangular blocks) with a flat car floor. However, with the frequent transportation of tracked vehicles and wheeled vehicles in China, higher requirements are put on the safety, reliability and rapidity of binding reinforcement. The existing binding and reinforcing modes of the universal flat car have the following problems: firstly, bending deformation and even pulling out of the curium nails or the round steel nails occur, so that the wheel guard reinforcement is invalid; the wooden shielding is easy to crack, so that the reinforcement strength is reduced; ping Chemu when the floor is decayed or cracked, the holding force of the cramp or round steel nails is affected, so that the reinforcement strength is weakened. Secondly, wood floor flatcar transportation is adopted, according to the requirement of 'reinforcement', the positions of cracks and joints of the floor are avoided by nailing, loading is required to be adjusted repeatedly at all times, the compactness of the general flatcar wood particle reinforced composite floor is high, nailing and dismantling operations are difficult when reinforcement is carried out, the labor intensity is high, and therefore the operation efficiency is low. Thirdly, triangular blocks, square woods and curium nails used for shielding and reinforcing the tracked vehicle and the wheeled vehicle are disposable spare parts, and the disposable wooden shielding and recycling value is low, so that larger resource waste is caused. Fourthly, the general flat car nailing operation causes serious damage to the floor, so that the vehicle maintenance period is short, and the vehicle application cost is increased. Wherein the pine floor is in the form of an extended crack; the composite floor is in the form of local block falling off.
