Novel railway four-wheel flat car structure

The utility model discloses a novel railway four-wheel flat car structure. The device comprises a bottom connector and a cargo carrying middle plate, the bottom connector is fixedly installed at the lower end of the cargo carrying middle plate. The extension side plate can be well supported by an inclined plane fixing and pulling block consisting of an inclined plane welding block, a plane supporting block and a bottom bolt; therefore, the connecting hinge is prevented from being broken and deformed; the top end of the slope fixing pulling block and the lower end of the cargo carrying middle plate are located on the same straight line. Therefore, the contact area is increased through the plane supporting block at the upper end of the slope welding block; the supporting is more stable and firmer; and when the cargo carrying middle plate is full of cargoes, a rope can be fixed to a bottom bolt at the lower end of the plane supporting block, so that personnel pull and transport the cargoes through the rope, or t
