Abstract
The utility model relates to a plat car frame of a semi-trailer. The plat car frame is a frame structure which is formed of welding two roots of curb girders, two roots of middle carlings and a plurality of beams, wherein, the carlings are welded to H-shaped by an upper wing panel, a web and a lower wing panel. A web stiffener is welded respectively between the upper wing panel and the lower wing panel on the mutual relative direction of the heads of the two carlings, and a superposing plate is welded on the lower side of the lower wing panel of the head of each carling. The plat car frame of the utility model is designed with an optimal structure by a computer, high strength low alloy steel sheet materials are adopted by the carlings, and the light weight and the small volume are done in conditions of satisfying the strength and the rigidity. The manufacturing quality is enhanced by adopting the welding technique of buried arc welding, thus the plat car frame of high bending strength and strong carrying capacity is obtained.
Description
Technical field
The utility model relates to a kind of vehicle frame, is a kind of superimposed trailer Platform trailer frame specifically.
Background technology
Highway freight is the main mode of transportation, at the land conveyance of developed country's superimposed trailer as main flow, played the part of the key player, but in China, the use of superimposed trailer also is in the starting stage.Obviously, the vehicle frame of this class trailer should have certain intensity and rigidity, just can bear bigger carriage load, existing vehicle frame is often for the bigger load of stand under load, and it is stupid, big, stupid, thick that vehicle frame is manufactured, and both waste material increased manufacturing cost, increase carriage load again, and transportation function is single.After the accession to WTO, domestic freight logistics accelerated development, be badly in need of modernization, intensive, efficiently, transportation mode and equipment efficiently.
The utility model content
The utility model provides a kind of bearing load big in order to overcome the defective of prior art, and rational in infrastructure, light self-weight, the Platform trailer frame of long service life.
The utility model Platform trailer frame is by longeron and some framed structures that crossbeam is welded of two side bars, two centres; Wherein longeron is welded into I shape by upper flange, web and lower wing plate, and the web top is straight, and its height of head is little, and front view is
Shape; The horizontal section of lower wing plate is
Shape, its width is identical with upper flange; Weld a web brace panel respectively between upper flange on the direction and the lower wing plate toward each other at two longeron heads, and a spacing is arranged between web brace panel and the web; Welding superimposed plates below the lower wing plate of each longeron head, superimposed plates shape and lower wing plate match.
The utility model Platform trailer frame wherein is provided with several chain rope fixed orifices along the side bar inboard.
The utility model Platform trailer frame wherein also is provided with several freight container lockhole seats along the side bar inboard.
The utility model Platform trailer frame, wherein upper flange, web and lower wing plate are selected high strength low alloy steel sheet material for use.
The utility model Platform trailer frame, wherein the vehicle frame length overall is 12～14 meters, 2.4～2.5 meters of width, 480～550 millimeters of height.
The utility model Platform trailer frame is through the computer optimization structure design, and longeron is selected high strength low alloy steel sheet material for use, is satisfying under the prerequisite of strength and stiffness, accomplish in light weight, volume is little; Adopt the submerged arc-welding welding technique, improve build guality, thereby it is big to obtain bending strength, the Platform trailer frame that load-carrying capacity is strong.
