Description
Technical field
The present invention relates to freight container, relate in particular to a kind of Undercarriage structure of freight container.
Background technology
Freight container at first used beginning from 1956 in the U.S., and through 40 years of development, the containerzation transportation is widely used in the whole world.Traditional goods general purpose container generally is made up of a pair of side wall, door end, front end, top board, floor and Undercarriage structure.Undercarriage structure and floor mutual group become the carrying structure of goods in the case.In decades, people to mainly by two longitudinally the Undercarriage structure formed of bottom side beams and many foundation crossbeam be accustomed to, what it was looked is the study plot plate structure.Though in the last few years, container designs person and user wished and attempted with improvement plate structure and all fail to be effective to reduce its cost.
Traditional Undercarriage structure of freight container is by every foundation crossbeam two ends and bottom side beams welding, constitutes the integral body of rigidity, lays the wood covering of 28 millimeters thick on bottom cross beam, constitutes loading ground.For satisfying freight container ISO test, bottom cross beam is arranged closely, and quantity is a lot, and bottom cross beam need adopt thicker steel (being generally 4～4.5 millimeters) could test the bottom cross beam high material consumption by ISO.The floor of tradition freight container is a wood covering, need to adopt special hard wooden floor, the wood covering opposite sex of poor quality is big on the one hand, price is expensive, cost is high, and be subjected to the influence of factor such as wood covering short supply: wood covering thickness also big (28 millimeters) on the other hand, wood covering weight is big, makes that the casing deadweight is heavier.
Summary of the invention
The technical matters that the present invention will solve is, a kind of Undercarriage structure of later-model freight container is provided, can reduce the quantity of former container bottom cross beam, thereby reduce the deadweight and the economical with materials of casing, another technical matters that the present invention will solve is, by adopting thin plate steel instead of wood plate to come Manufacture of Floor, the timber of saves valuable and cost-cutting.
The technical scheme that the present invention addresses the above problem is: the Undercarriage structure that designs a kind of freight container, comprise bottom side beams, with described many foundation of bottom side beams bonded assembly crossbeam, it is characterized in that, also comprise at least two longerons that longitudinally are connected with described bottom cross beam, general frame body of common composition is coated with steel plate on described frame body.
Undercarriage structure by freight container provided by the invention, by many longerons that are attached thereto are set on body transom, can make the support stiffness and the intensity of container base improve, can reduce the quantity of bottom cross beam, bottom cross beam and longeron can adopt thinner steel plate, adopt Steel floor to substitute wood covering, can test by ISO, thereby reduced the material cost and the deadweight of casing, made container production and cost avoid being subjected to the restriction of wood covering supply, improved the carrying capacity of casing simultaneously.Below in conjunction with accompanying drawing, further specify the present invention with preferred embodiment.

Specific embodiment
As shown in Figure 1, the novel container Undercarriage structure mainly is made up of two foundation curb girders 1, some longerons 2, some bottom cross beams 3, weld with the side of bottom side beams 1 respectively at bottom cross beam 3 two ends, and longeron 2 intersects and welding with bottom cross beam 3, constitutes a complete rigid frame structure.Compare with traditional regular general cargo general purpose container Undercarriage structure (shown in Figure 6), its difference is, Undercarriage structure of the present invention has increased some longerons 2, thereby guaranteeing under the prerequisite of underframe by the ISO test, the bottom cross beam spacing L1 of Undercarriage structure can be far longer than the bottom cross beam spacing L3 of traditional Undercarriage structure, thereby the quantity of bottom cross beam is significantly reduced.
As shown in Figure 1 and Figure 2, some longerons 2 intersect and welding with some bottom cross beams 3, and longeron 2 distributes along the length direction of bottom cross beam 3.Test by ISO with less sectional dimension H2, B2 and thin wall thickness T 2 for guaranteeing longeron, girder space L2 should be less than or equal to 600mm, reasonable is to be less than or equal to 300mm, preferably equal the width 180mm of container floor test wheel 4 (referring to Fig. 2), making has at least a longeron directly to support test wheel 4, simultaneously the bottom cross beam 3 spacing L1 between adjacent should select suitably, should not be too big.
Be on bottom cross beam 3, to be provided with groove 6 or the hole that a plurality of openings that distribute at certain intervals make progress as shown in Figure 3, can place or pass groove 6 or hole and bottom cross beam 3 crossing and welding;
Be between two adjacent bottom cross beams 3, to be provided with many longerons 2 as shown in Figure 4, and longeron 2 and two adjacent bottom cross beams 3 are welded to connect.
In said structure, it is the steel making of L type, I type, T type, U type, C type or frame type that bottom cross beam 3 and longeron 2 can adopt cross sectional shape.
As Fig. 2, shown in Figure 5, bottom side beams 1, longeron 2, bottom cross beam 3 and floor 5 welding, the integral body and the loading ground of a rigidity of formation.After weld with longeron 2, bottom cross beam 3 on floor 5, increased the resistance to bending of longeron and bottom cross beam, helped reducing its sectional dimension, reduced weight, steel plates are adopted on floor 5.According to the present invention, steel floor 5 can adopt thickness to be not more than 4 millimeters steel plate.
As Fig. 7, shown in Figure 8, on the bottom cross beam 7 of traditional Undercarriage structure, need to lay wood covering 8, constitute the loading ground of freight container.Fig. 9 is novel Undercarriage structure bottom cross beam 3 and being connected of steel floor 5, and Figure 10 is traditional Undercarriage structure bottom cross beam 7 and being connected of wood covering 8.Compare with conventional confguration, the advantage of Undercarriage structure of the present invention is as follows:
(a). the height H 1 of the bottom cross beam 3 of novel Undercarriage structure makes the section material distribution of bottom cross beam 3 more help the bottom cross beam bending resistance greater than the height H 3 of the bottom cross beam 7 of traditional Undercarriage structure;
(b). bottom cross beam 3 is welded as a whole with steel floor 5, and the material of the near zone of steel floor 5 and bottom cross beam 3 welding will improve the resistance to bending of bottom cross beam 3 greatly;
Thereby under the condition by the ISO test, the wall thickness T 1 of bottom cross beam 3 (the present invention) is thinner, generally be about 2～3 millimeters, and the wall thickness T 3 of bottom cross beam 7 (prior art) is thicker, is generally 4～4.5 millimeters.The base width B 1 of bottom cross beam 3 is close with the base width B 3 of bottom cross beam 7, and the height H 1 of bottom cross beam 3 is greater than the height H 3 of bottom cross beam 7, but comprehensive, the weight ratio bottom cross beam 7 of bottom cross beam 3 in light weight.
Steel floor is a general steel plate, with wood covering relatively: in light weight, cost is low, and the market supply of material is stable.Under the condition by the ISO test, novel Undercarriage structure has reduced the quantity of bottom cross beam and has alleviated the bottom cross beam deadweight, and adopts sheet steel to replace wood covering, thereby novel Undercarriage structure has reduced material cost than traditional Undercarriage structure; Novel in addition steel floor substitutes traditional wood covering, has avoided the influence of wood covering short supply to container production and cost.This novel Undercarriage structure and steel floor have been realized reduction container material cost and have been reduced the purpose that the casing deadweight improves maximum loading.
