The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
embodiment 1
As shown in Figure 4,5, in the present embodiment, goose neck tunnel structure applications is in chassis of container, underframe comprises bottom side beams 1, the goose neck tunnel structure between two bottom side beams 1 of two parallel longitudinal settings and is layed in the structural base plate 4 of goose neck tunnel, goose neck tunnel structure comprises: goose neck tunnel bottom cross beam 10, be located between two bottom side beams 1; And at least one pair of gooseneck support portion 20, described each is fixedly installed on goose neck tunnel bottom cross beam 10 lower surfaces to compartment of terrain, gooseneck support portion, that is and, each is discrete setting to gooseneck support portion.Between every pair of gooseneck support portion 20, jointly limit goose neck tunnel space S with goose neck tunnel bottom cross beam 10 lower surfaces.Every pair of goose neck tunnel structure is symmetrical, and Fig. 5 only illustrates half part of goose neck tunnel structure, and in fact, other half part therewith part is symmetrical.
The goose neck tunnel space of goose neck tunnel structure qualification of the present utility model is identical with the effect in the space that in background technology, gooseneck frid is bent to form, and all can coordinate the gooseneck part of containerized shipment car.Because the utility model has been cancelled whole gooseneck frid, with two gooseneck support portions, limit goose neck tunnel space, simplified goose neck tunnel structure, make it be easy to assembling, and goose neck tunnel scantling of structure is little, is convenient to handling.
Wherein, the lower surface that is welded in this goose neck tunnel bottom cross beam of two gooseneck support portion 20 symmetries of every pair, the shape of the inner side of gooseneck support portion coordinates with the gooseneck shaped of containerized shipment car.Gooseneck support portion 20 comprises a pair of supporting leg 21, and it can also can be tubing for by steel plate bending moulding, and can be sealed by shrouding the two ends of tubing.
Wherein, goose neck tunnel bottom cross beam 10 is welded between two bottom side beams 1.Goose neck tunnel bottom cross beam 10 is provided with underframe base plate 4, and in the present embodiment, underframe base plate 4 is wood covering.
embodiment 2
As shown in Figure 6,7, the difference of the present embodiment and embodiment 1 is: gooseneck support portion 20 comprises a pair of gooseneck bottom side rail 22, gooseneck bottom side rail 22 is welded in bottom side beams 1, and the upper surface of gooseneck bottom side rail 22 is fixed on goose neck tunnel bottom cross beam 10 lower surfaces, the shape of the inner side of every pair of gooseneck bottom side rail 22 coordinates with the gooseneck shaped of containerized shipment car, between every pair of gooseneck bottom side rail, jointly limits goose neck tunnel space S with goose neck tunnel bottom cross beam 10 lower surfaces.
embodiment 3
As shown in Figure 8,9, the difference of the present embodiment and embodiment 1 is: gooseneck support portion 20 also comprises a pair of gooseneck bottom side rail 22, and gooseneck bottom side rail 22 is welded in bottom side beams 1, and the upper surface of this gooseneck bottom side rail 22 is fixed on goose neck tunnel bottom cross beam 10 lower surfaces.The inner side of being located at gooseneck bottom side rail 22 of supporting leg 21 sealings, limits goose neck tunnel space S jointly with goose neck tunnel bottom cross beam 10 lower surfaces between supporting leg 21.
Wherein, supporting leg 21 lower surfaces flush with gooseneck bottom side rail 22 lower ends.By supporting leg 21 and the common goose neck tunnel bottom cross beam 10 that supports of gooseneck bottom side rail 22, improve the intensity of goose neck tunnel structure.
In addition, in the present embodiment, underframe base plate 4 is for covering and be welded in the steel floor of goose neck tunnel bottom cross beam 10 upper surfaces.
embodiment 4
As shown in Figure 10,11, the difference of the present embodiment and embodiment 3 is: underframe base plate 4 comprises the first base plate 41, and it is wood covering, and the first base plate 41 is positioned on gooseneck bottom side rail 21, goose neck tunnel bottom cross beam 10, between the first base plate 41, and is erected on the upper surface of gooseneck bottom side rail 22 at least partly.Underframe base plate 4 also can comprise the second base plate 42, and it is steel floor, and the second base plate 42 is welded in and is positioned on goose neck tunnel bottom cross beam 10, with the upper surface flush of the first base plate 41 of both sides.
In this scheme, goose neck tunnel bottom cross beam 10, for being erected on gooseneck bottom side rail 22, is therefore convenient to dismounting.
In addition, preferred, supporting leg 21, gooseneck bottom side rail 22 and bottom side beams 1 surround cavity, cavity outer end, and the outer end of goose neck tunnel structure, is sealed by shrouding (not shown).
embodiment 5
As shown in Figure 12,13, goose neck tunnel structure is located on chassis of container, and this underframe comprises that two bottom side beams 1, the first base plate 41 and the second base plate 42, the first base plates 41 can be wood covering, and the second base plate 42 can be steel floor.Goose neck tunnel structure comprises at least one pair of spaced gooseneck support portion 20,, each is discrete setting to gooseneck support portion, gooseneck support portion 20 comprises supporting leg 21 and gooseneck bottom side rail 22 gooseneck bottom side rails 22, one side of gooseneck bottom side rail 22 is welded in bottom side beams 1, the first base plate 41 is positioned on gooseneck bottom side rail 22, supporting leg 21 is welded in the opposite side of gooseneck bottom side rail 22, and lower end flushes with the lower surface of this gooseneck bottom side rail 22, the inner side of every pair of cervical branch support part 20 and the second base plate 42 lower surfaces limit goose neck tunnel space S jointly.
Wherein, the upper surface flush of the first base plate 41 and the second base plate 42.
Wherein, every pair of gooseneck support portion 20 is symmetrical arranged, and the shape of the inner side of gooseneck support portion 20 coordinates with the gooseneck shaped of containerized shipment car.
The present embodiment has been cancelled whole gooseneck frid equally, and it limits goose neck tunnel space with two gooseneck support portions, and goose neck tunnel structure is simplified more, be easy to assembling, and goose neck tunnel scantling of structure is little, is convenient to handling.
The kind that should be appreciated that the girder constructions such as the goose neck tunnel bottom cross beam that relates in the utility model, gooseneck bottom side rail is not limit, and can be square tube, C type bending steel or H shaped steel.In addition, goose neck tunnel bottom cross beam can be the similar structure of bottom cross beam with freight container.Gooseneck support portion can be to be welded in goose neck tunnel structure, also can be detouchable setting.
