Specific implementation mode
The content of the utility model is further explained and is illustrated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the expanding type U-shaped cargo box structure of the utility model, including foreboard assembly 1, side plate assembly 2, bottom plate
Assembly 3 and back plate assembly 4 reach reduction weight, carry by adjusting the mainboard structure of each component and the welding position of reinforcing beam
The purpose of the integral strength of high producing efficiency and increase container.
As shown in Fig. 2, shown side plate assembly includes side plate mainboard 11, side wing 12, side plate upper ledge 13 and side plate rear column
14, side plate upper ledge 13 is directly welded on side plate mainboard 11, and side plate upper ledge uses quarter bend, increases the anti-case effect that rises, side wing 12
It is welded in 11 lower end of side plate mainboard and increases side plate overall structure, while is beautiful.Side plate rear column 14 passes through profiling and side plate mainboard
11 multiple tracks fold-type outwardly protrudes structure and is bonded to each other welding, ensures rear strength and the anti-case problem that rises, while improving aesthetics；
It welds side wing and increases intensity in container lower end.Side plate mainboard 11 increases intensity, while removing horizontal, vertical by partial structurtes bending
Girder construction reduces welding bead, reduces side plate assembly weight.
As shown in figure 3, back plate assembly include back plate frame 21, back plate upper ledge 22, back plate mainboard 23, back plate lower frame 24 and
Strengthens angle 25.Back plate mainboard 23 is designed using die mould bending, is formed the corrugated structure of c-type flaring fold-type or V-type fold-type, is connected C
Type is flared the vertical beam of fold-type or V-type fold-type, and no crossbeam realizes loss of weight, reduces cost and subtract the purpose of welding bead.Back plate frame 21,
Back plate upper ledge 22 and back plate lower frame 24 are welded in respectively on back plate mainboard 23, reinforce the bonding strength of each component by strengthens angle 25.
In addition, back plate mainboard can also be flat plate, the bending structure enumerated is not limited to the present embodiment.
As shown in figure 4, floor pan assembly includes bottom plate mainboard 31, underframe longitudinal member 32, bottom plate middle cross beam 33, bottom plate side crossbeam
34, bottom plate overturns tail boom 36 after seat beam 35 and bottom plate.Wherein underframe longitudinal member 32, bottom plate middle cross beam 33, bottom plate side crossbeam 34 and bottom
Plate mainboard 31 directly welds, while tail boom 36 is welded with side wing 12 after bottom plate side crossbeam 34, bottom plate, increases the monolithic devices of container
Property.Bottom plate middle cross beam 33 uses oversleeve structure, 33 both ends of bottom plate middle cross beam not to be welded with underframe longitudinal member 32, and outside patch weldering adds
Strong slot avoids the problem that welding bead cracking occurs between bottom plate middle cross beam 33 and underframe longitudinal member 32 when bottom slab stress deforms.Bottom plate is total
At the structure using twice or multiple tracks longeron, crossbeam is arranged in longeron both sides and centre, and the crossbeam of both sides extends bottom plate mainboard,
Bendable bearing diagonal is welded in bottom plate both sides simultaneously, increases cargo floor and side plate junction intensity, increases whole the anti-of container and rises
