Description

TECHNICAL FIELD

[0001] The present application relates to a reinforcing device for railway flat cars and a railway flat car. BACKGROUND

[0002] At present, the railway flat cars for transporting tracked vehicles, wheeled vehicles, steel, wood, automobiles, mechanical equipment, containers and other goods in China mainly use pine wood or wood particle reinforced composite material floors. When various types of tracked vehicles and wheeled vehicles are transported by railway general flat cars, they need to be reinforced by using steel wire rope to pull and combine with nails to fix the wooden cover. The square wood (triangular cover) is used to cover the front and rear of the vehicle on each side of the track (tire), and the square wood (triangular cover) is nailed to the flat car floor with a pry nail. However, with the frequent transportation of tracked vehicles and wheeled vehicles in China, higher requirements are put forward for the safety, reliability and rapidity of the binding and reinforcement. The existing binding and reinforcement method of general flat cars has the following problems: first, the pry nails or round steel nails are bent and deformed, or even pulled out, resulting in the failure of the wheel cover reinforcement; the wooden cover is prone to cracking, resulting in a decrease in reinforcement strength; when the flat car wooden floor is rotten or has cracks, the pry nails or round steel nails are affected, thereby weakening the reinforcement strength. Second, when transporting with a wooden floor flat car, according to the "reinforcement" requirements, the nailing should avoid the floor cracks and joint positions, resulting in the need to repeatedly adjust the loading position during loading. The density of the general flat car wood particle reinforced composite floor is high, making the nailing and removal operation difficult and labor-intensive, thus resulting in low operation efficiency. Third, the triangular cover, square wood and pry nail used for the reinforcement of the tracked vehicle and wheeled vehicle cover are one-time spare parts, and the one-time wooden cover has low recycling value, resulting in a large waste of resources. Fourth, the nailing operation of the general flat car causes serious damage to the floor, resulting in a short vehicle maintenance cycle and increased vehicle operation cost. The pine floor shows an extension cracking; the composite floor shows a local block shedding. SUMMARY

[0003] Therefore, one object of the present application is to provide a reinforcing device for railway flat cars, which can replace the existing wooden cover reinforcement method and does not need to use pry nails or round steel nails to nail the reinforcing device, and the reinforcement method is more secure and reliable without damaging the floor.
