A side beam of a railway flat car underframe

Abstract

The invention relates to a side beam of a railway flat car underframe, which comprises a horizontally arranged H-shaped steel beam, the H-shaped steel beam includes an upper airfoil, a web and a lower airfoil, and the lower airfoil is along the H-shaped steel beam. The length direction is a fish-belly structure with a wide middle and narrow sides; on one side of the web, a plurality of column inserts distributed along the horizontal direction are arranged, and the column inserts are groove-shaped structures formed by bending steel plates. The sides are fastened to the web and the tank is in the vertical direction, and the column inserts protrude from the upper wing surface in the horizontal direction; a bolted beam is arranged between every two column inserts, and the bolted beam includes two parallel and spaced longitudinal Beams, the two ends of each longitudinal beam are respectively fastened to the side of the column insert, and a plurality of bolted columns are arranged at equal intervals between the two longitudinal beams, and the bolted columns protrude from the upper wing in the horizontal direction; One side of the web is also provided with a plurality of rope bolts distributed at intervals along the horizontal direction, and the rope bolts are fastened and connected to the web below the bolted beam. The present invention can be widely used in the underframe of ordinary railway flat cars or shared flat cars.

Description

Technical field [0001] The invention relates to a side beam, in particular to a side beam used for the underframe of a common railway flat car or a shared flat car. Background technique [0002] Railway flat cars generally refer to ordinary railway flat cars or shared flat cars, which are mainly used to transport goods such as steel, mechanical equipment, wheeled equipment, and containers. [0003] Since railway flat cars need to load goods such as wheeled equipment that are larger in appearance or can be loaded and unloaded by themselves, railway flat cars adopt a full-frame load-bearing structure, and generally do not have fixed end walls and side walls. Therefore, in addition to the friction with the floor, the loading and reinforcement of goods on the railway flat car generally requires the use of ropes and other reinforcement equipment to bind the goods to the bolt joints specially set on the underframe of the flat car. The tie-down bolt joints of flat cars in our country are...

AI Technical Summary

Problems solved by technology

In the application of railway flat cars, since the number and position of the tie points of the existing flat cars are fixed, and the goods loaded on the flat cars are of various specifications, there are often insufficient number of tie points or mismatching positions of the tie points when bundling. It is necessary to lengthen the binding rope, which is inconvenient for the binding operation

In addition, when the current railway flat car is loaded with wheeled equipment and other goods, because the rope bolts and column insertion structures of the current railway flat car are not suitable for the use of reusable hook-type binding straps that are often used in wheeled equipment transportation, it is still only possible Reinforcement with one-time reinforcement materials such as iron wire, high loading and reinforcement costs and long reinforcement time
