The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Chassis of container shown in Fig. 4,5, comprise that in its both sides two bottom side beams 22, a plurality of horizontal welding cross sectional shape between two bottom side beams 22 that vertically are provided with are the bottom cross beam 21 of C type, laterally run through the slot 25 of two bottom side beams 22 and be arranged on the front end underbeam 24 of its front end and be positioned at the threshold 23 of its rear end, adopt between above-mentioned each parts to be welded to connect.
As shown in Figure 6, it is the slot top board 252 that slot curb girder 251, the crosswise fixed of C shape is connected in two slot curb girders, 251 tops that slot 25 includes the cross section that is positioned at its both sides, by general machine up general knowledge as can be known, can connect with welding between slot top board 252 and the slot side plate 251, also can adopt one-time formed method processing.Be welded with slot base plate 253 in the bottom of slot 25, and the surface on slot floor 253 is 115mm-117mm to the distance P between the lower surface of slot top board, this distance meets the regulation of ISO freight container international standard; Behind the gear shaping insertion slot that guarantees fork truck, slot has enough intensity, and the thickness of general slot top board is more than 2mm.Respectively be provided with a wood covering 26 in the both sides of slot 25, this wood covering 26 is layered on the bottom cross beam 21 and by rivet and is connected with bottom cross beam 21; Be welded with the bending steel plate 254 of cross section respectively for " L " shape in the outside of two slot curb girders 251, one end of wood covering 26 rides on this bending steel plate 254, and captive joint with the bending steel plate by rivet, its other end rides on as shown in Figures 7 and 8 the threshold 23 and the bending groove 230 and bending groove 240 of front end underbeam 24 separately accordingly, and the upper surface of bending groove 230, bending groove 240, bottom cross beam 21 and bending steel plate 254 is concordant, so, can guarantee that wood covering 26 is in straightened condition; Simultaneously, smooth for the upper surface that guarantees whole underframe, the upper surface of bending steel plate 254 equals the thickness of wood covering 26 to the distance of slot cover top surface, so, makes that the upper surface of wood covering 26 is concordant with the upper surface of slot top board.
By general machine up general knowledge and mechanics general knowledge as can be known, the cross sectional shape of bottom cross beam 21 and slot curb girder 251 also can be I type or inverted T shape.
By the general general knowledge of this area as can be known, corrugated bar floor or dull and stereotyped steel floor can also be adopted in the floor, can reach the technique effect identical with wood covering.
Said structure because the upper surface of slot top board 252 is concordant with the upper surface of wood covering 26, has reduced the height on floor thus, thereby, increased the interior sky of casing, improved the efficiency of loading of casing.
Simultaneously, said structure also brings a problem, because the height on floor lowers, the height that also just means bottom cross beam reduces, if the thickness of bottom cross beam and overall width are also with of the prior art identical, then the intensity of this underframe certainly exists the risk that does not satisfy operating needs, for this reason, the method that can adopt be the sectional dimension that increases the distribution density of bottom cross beam and/or increase single bottom cross beam, also can adopt the intensity better material.From the material angle, adopt yield limit greater than
The high strength steel of 450Mpa is more reasonable, and promptly bottom cross beam 21 and/or bottom side beams 22 can adopt high strength steel, as the high strength steel of ZJ700W, like this, can under the situation that does not increase bottom cross beam 21 and/or bottom side beams 22 cross-sectional areas, reduce its height, and can satisfy requirement of strength.
Resistance to overturning from Undercarriage structure, in such scheme, realized by rivet with only being connected of slot on the floor, so, exist in slot when stressed, its the stressed bad situation that passes to other framing members in the underframe, this has certain risk under the stressed excessive situation of slot, for this reason, need with slot with captive joint with the bottom cross beam that it closes on, to share the stressed of slot, as shown in Figure 9, add between slot curb girder 251 and the bottom cross beam 21 the most adjacent with it and be connected reinforcement 29, an end of this connection reinforcement 29 and the outside of slot curb girder 251 are welded to connect, and its other end is welded to connect with the bottom cross beam 21 the most adjacent with slot curb girder 251.By general mechanical general knowledge as can be known, this connection reinforcement 29 is plate or column piece etc., all can reach identical technique effect.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
