Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-3, in the embodiment of the utility model, a fixed back ramp frame structure of low flat-bed semi-trailer, including longeron 1, outer beam 2 and crossbeam 3, longeron 1 is the main tributary supporting beam of frame, constitute I-shaped structure by web 101 and pterygoid lamina 102 welding, web 101 unloading downward sloping setting on the longeron 1, and web 101 bottom runs through the automobile body and welds fixed back ramp 5, cut out a plurality of evenly distributed's I-shaped groove 11 on the web 101, crossbeam 3 passes I-shaped groove 11 and longeron 1 assembly connection on longeron 1 web 101, 3 both sides of crossbeam enclose into the frame main part with outer beam 2 welding, the welding of frame main part front end has gooseneck assembly 9, frame main part front end lower extreme swivelling joint has landing leg 8, the welding of frame main part rear end both sides has a plurality of evenly distributed's.
When carrying out cargo handling, because the setting of web 101 unloading downward sloping on longeron 1, make the semitrailer rear end form a ramp, the minimum ground clearance of semitrailer afterbody has been reduced, the height of getting on the goods of semitrailer rear end has been reduced, be convenient for cargo handling, and tire transition deck 4 replaces the truss as the support, be located between the wheel, through the space between the tire, the rational utilization space, offset tire transition deck self structural thickness, lighten frame weight, reduce the automobile body height, be convenient for cargo handling.
