The specific embodiment
Below we come freight container of the present utility model done further with specific embodiment in conjunction with the accompanying drawings and elaborate; in the hope of understanding structure of the present utility model and make use more cheer and brightly, but can not limit protection domain of the present utility model with this.
As shown in Figure 3, structural representation for a kind of chassis of container of the present utility model, this freight container includes a underframe 1 that is used for bearing goods at least, this underframe 1 be by in the bottom side beams 11 of its both sides, at the back end floor beam 13 and the front end cross beam 14 at its vertical two ends, be arranged at the frame body that the bottom cross beam 12 between the bottom side beams 11 is constituted, be equipped with back of half bearing shell 2 on the underframe 1, the welded top of bottom side beams 11 is in the lower surface of back of half bearing shell 2.
As shown in Figure 4, bottom side beams 11 is that the cross section is the through beam of L shaped structure, when specifically welding fixedly, be that welded top with L shaped bottom side beams 11 is in the lower surface of back of half bearing shell 2, and bottom cross beam 12 still is vertically fixed between the two foundation curb girders 11, do not influence bottom cross beam and bottom side beams and form framed structure, 2 of back of half bearing shells form smooth integral structure in the freight container.In conjunction with shown in Figure 7, freight container of the present utility model also includes the side plate 4 that is arranged at the casing both sides, and side plate 4 lower edges are welded on the back of half bearing shell 2.The general thought of present embodiment is that back of half bearing shell is made a wide structure, and this back of half bearing shell extends bottom side beams, and bottom side beams directly is weldingly fixed on the bottom of back of half bearing shell.
In embodiment of the present utility model, back of half bearing shell 2 directly extends to the top of two bottom side beams 11, and its width range is between 2300mm~3500mm, and concrete size is determined according to the width of casing.
As shown in Figure 5, the front-end and back-end of back of half bearing shell 2 are overlapped on respectively on front end cross beam 14 and the rear end 13, front end cross beam 14 is provided with the support angle steel 141 that carries out butt welding with back of half bearing shell 2, the upper surface of threshold 13 has one towards the casing outside and the downward-sloping gradient, and the lower surface of back of half bearing shell 2 is welded on the top to descending slope.In freight container of the present utility model, underframe 1 also includes fork pockets 15, and fork pockets 15 top boards are provided with deep beam 151, and deep beam 151 can be U-shaped, V-arrangement or other similar structures.
As shown in Figure 6, the front end of back of half bearing shell 2 is provided with the breach of being convenient to the headpin field weld 21.
In freight container of the present utility model, back of half bearing shell can be made with a monoblock steel plate, does not have weld seam like this, directly is exactly a big smooth base plate.In the utility model, also can be spliced to form the smooth base plate 3 of bulk with polylith unit steel plate 31 according to actual conditions.The form of splicing can be the form of vertically welding, and also can be the form of horizontal welding, and Fig. 8 is exactly wherein a kind of splicing form.
Figure 10, Figure 11, shown in Figure 12 as shown in Figure 9,, structural representation for another chassis of container of the present utility model, be equipped with base plate 5 on this chassis of container, this base plate comprises the polylith back of half bearing shell 51 that is provided with at interval along the length direction of bottom side beams, be provided with the timber apron 52 that is complementary with its thickness between the polylith back of half bearing shell, and the upper surface of steel floor 51 is concordant with the upper surface of timber apron 61.In the present embodiment, bottom side beams 6 includes back of half bearing shell support portion 61 and wood floors support portion 62, and back of half bearing shell support portion 61 and wood floors support portion 62 are connected as a single entity.In actual production process, also can as required back of half bearing shell support portion and wood floors support portion segmentation making fixedly be welded as a whole again.
Preferably, in embodiment of the present utility model the cross-sectional plane of bottom side beams can also for inverted T-shaped, I shape, C shape or
One of dependency structures such as shape.In addition, bottom side beams of the present utility model is weldingly fixed on the bottom of back of half bearing shell, and this work can externally be finished, and with the welding deformation of control back of half bearing shell, and reduces the welding job amount, even maintenance occurs also being convenient to when distortion waits weld defect.
Generally speaking, that the underframe of freight container of the present utility model has changed is time-consuming when chassis top surface wrought iron base plate and bottom side beams in the past, the operational drawbacks of effort, makes the manufacturing of back of half bearing shell finish from the outside, is convenient to control welding quality and welding deformation.
