Embodiment 1
[0037] Attached below Figure 1-Figure 10 The present invention is described in detail, specifically, the structure is as follows:
[0038] This embodiment provides a side beam of a railway piggyback transport vehicle, which adopts a variable cross-section box-shaped structure welded by plate girders, and the overall structure is fish-bellied; it includes an upper cover plate 1, an end side beam 2, a connecting plate 3, a reinforcement Plate 4, middle side beam 5, reinforcement plate 6, reinforcement beam I7, reinforcement beam II8, reinforcement beam III9, pedal 10; upper cover plate 1, end side beam 2, reinforcement beam I7, reinforcement beam II8, connecting plate 3 Welding to form a variable-section box-shaped structure at the end of the side beam; welding of the upper cover plate 1, middle side beam 5, and reinforcement beam III9 to form a box-shaped special-shaped structure at the middle of the side beam.
[0039] Specifically, there are two middle side beams 5, and bot...

The invention discloses a railway piggyback transport vehicle side beam, and solves the problems that in the prior art, a side beam is complex in structure and large in weight and cannot meet piggyback transport requirements. A variable cross-section box type structure formed by assembling and welding plate beams is adopted, the overall structure is in a fish belly shape, the overall structure iscompact and reasonable, and the dead weight and the height of a concave bottom bearing surface can be effectively reduced. According to a technical scheme, the railway piggyback transport vehicle sidebeam comprises two middle side beams which are oppositely arranged, and two ends of each middle side beam are fixedly connected to end side beams respectively; the two opposite end side beams are connected through a connecting plate to form an integral frame; reinforcing plates I and reinforcing beams II are sequentially arranged on the outer sides of the end side beams; upper cover plates are arranged above the end side beams; and the upper cover plates, the end side beams, the reinforcing beams I, the reinforcing beams II and the connecting plates form a variable cross-section box type structure at the end parts.
Description
technical field [0001] The invention relates to the field of railway piggyback vehicles, in particular to a side beam of a railway piggyback vehicle. Background technique [0002] Railway piggyback transportation is a combined road and railway transportation method, which means that freight cars or containers are directly driven on or hoisted to the piggyback transport vehicle for transportation, and then driven off or hoisted from the vehicle to the ground station after reaching the destination . Railway piggyback transport can realize seamless road-railway connection, reducing cargo loading and unloading and environmental pollution. [0003] At present, most of the existing railway vehicle underframes are assembled and welded into a box-shaped structure by center girders, side girders, and cross girders. The structure is complex, the welding workload is heavy, and the process control is difficult. The structure is heavy and has a high load-bearing surface. When used for...
