Description

Cargo-type container

Technical field

The present invention relates to a kind of cargo-type container.

Background technology

In Europe, inter-modal freight transportation (by highway, railway and ocean ferryboat) needs the maximum minimum freight container of conducting oneself with dignity of internal volume.Current Europe regulation, the extreme length of freight container is 13.6m, maximum width is 2.5m/2.55m.This width can hold the wide Standard pallet of two row 1.2m, and after considering actual gap, the thickness of leaving each sidewall in two side wall constructions for is about 40mm at the most.

Current long permutoid (swapbody) freight container of 13.6m that has.These freight containers have the steel wave-shaped side wall, and these sidewalls are able to special reinforcement along sidewall in (promptly on " 40 feet " position) on the position of the 12.2m of being separated by (40 feet), thereby form the long column of 12.2m (40 feet) actually.The I.S.O accessory (angle foundry goods) of a standard is arranged at the top of the long column of each 12.2m (40 feet), and this accessory allows to utilize known 12.2m (40 feet) long dilators (spreader) that have twist-lock connector that freight container is carried out top lift.In addition, the long freight container of standard fully loaded 12.2m (40 feet) can be stacked on the top of this freight container.

But, this freight container has such shortcoming, promptly can only be through rear end door loading or unloading goods, however most of on-highway tractor (having this size) all is a side curtain type, this side curtain type trailer major advantage is, allows to carry out the sidepiece loading and unloading.

The top structure of the long side curtain type permutoid of present normally used 13.6m freight container is thinner relatively.This is that the maximum side hole height of acquisition is necessary, and the admissible structure thickness to the top produces restriction (being not more than about 100mm usually) thus.Because same reason, the structural thickness of substrate must keep a minimum value (being about 250mm at present), and this can cause underlying structure to be highly susceptible to deflection, and when being in loading condition, bending phenomenon is very obvious.

Therefore, element stack that will fully loaded 12.2m (40 feet) is long is unpractical at the top of the long side curtain type freight container of a 13.6m, nor can be with the long side curtain type element stack of fully loaded 13.6m on the top of another freight container, because excessive basement flexure produces unacceptable load in the top of freight container below.In theory, the long unit of 13.6m with rigid sidewalls can be stacked on the side curtain type freight container, just can produce very big vertical squeese pressure in transportation, and the side curtain type freight container can not bear these longitudinal forces safely.

But, the strong long side curtain type freight container of 13.6m that needs also can be fully loaded with stacked and top lift.Top lift equipment is easy to obtain in most of port areas and through transport storehouse; But be not easy to obtain very the grab bucket lifting or the suspender lifting means of specialty.The hoisting crane that freight container is debarked from shipping all has top lift equipment, for the deck cargo on the ferryboat of coastal waters, is starved of and carries out lift onlift off system (LO-LO) operation.In addition, the freight container that transports of many ferryboaies is stacked on Maffi type platform/casing by bilayer the side belowdecks.These Maffi molding boxes have 70 tons capacity usually, and can utilize exclusive trail car to be rolled on the ship or from ship to roll down (RO-RO).At present, wasted valuable shipping space so have only a kind of single side curtain type freight container can utilize this system to carry.In fact, when only moving a freight container, operating personal also is necessary for two slots and pays.

Current, the long side curtain type freight container of 13.6m has I.S.O accessory (perhaps similar light-type accessory) usually in the 12.2m of its underlying structure (" 40 feet ") position.The purposes of these accessories is to allow freight container to be connected on autotruck (road chasses) (trailer), goods train or the ship's deck by twistlock.If each 12.2m in top structure (" 40 feet ") position is provided with a complete I.S.O accessory, and the accessory of the 12.2m of top and bottom (" 40 feet ") position couples together by structural " column " member, and so this freight container can carry out top lift and can be stacked.Unfortunately, this " column " can hinder and satisfactorily freight container be carried out the sidepiece loading and unloading.

A kind of mode that is used for overcoming this difficulty is, make " 40 feet " but column can remove like this and another difficulty can occur, promptly column is inevitable very heavy, and can't utilize manpower to remove safely.In addition, also be not easy at the top of these columns it to be connected on the freight container satisfactorily, because the column top is overhead too far away, therefore, the operator is not easy approaching.

In our International Patent Application WO 99/59899, a kind of laterally opened cargo-type container is disclosed, this freight container has an inclination strut, and this strut is connected between freight container end wall and the substrate separably, so that restriction substrate generation deflection.But because its length, this strut is a bit clumsy.

In our unexamined patent application GB-A-2353277 (being incorporated by reference the present invention) at this, a solution of the problems referred to above has been proposed, this scheme is a hinged door on the corner assembly that is installed in cargo-type container.

But, a kind of device that freight container is carried out reinforcement need be provided, this device is hinged as the door among the GB2353277, and just operation is more easy and purposes is more.

Summary of the invention

The invention provides a kind of cargo-type container, this freight container comprises substrate, the top, be positioned at assembling device and bearing set on the top, described assembling device is used for promoting this freight container and/or another freight container is stacked on described over top, described bearing set can move between the carrying position of a closure and a " loaded " position of opening, the carrying position is used for transmitting load between assembling device and substrate, in " loaded " position, described bearing set allows to enter from sidepiece, come cargo-type container is carried out loading and unloading, it is characterized in that, described bearing set comprises a framework and a strut, described framework is hingedly mounted on the freight container, so that can open from freight container one side oscillation, described strut is carried on the framework, and can move between retracted position and extended position with respect to framework, at retracted position, permission enters freight container from sidepiece, and at extended position, the end of strut is connected on the structure member of freight container.

What be fit to is that described bearing set is hinged on the root post that is fixed to this cargo-type container.Described column is such as being corner post or newel post.

Useful is that described framework extends between two hinges that separate.Described hinge preferred (but be not must) has limited a vertical basically hinge axis.

The description of preferred embodiment

In these accompanying drawings, same Reference numeral is represented same parts, in accompanying drawing 5 with accompanying drawing 4 in similarly parts with having " ' " Reference numeral represent.

As shown in accompanying drawing 1 to 3, the cargo-type container 1 among the present invention has a plurality of corner posts 3,4 at a substrate 2 and supporting top 5, and top 5 also is subjected to the supporting of three equidistant B-pillars 6 in addition, and these B-pillars 6 can move in a known way.As from accompanying drawing 2 and 3 clear see, the freight container sidepiece is closed by a curtain 7 that covers B-pillar 6, therefore, curtain 7 can be drawn back by side direction, so that freight container 1 is carried out loading and unloading.The position of freight container adjacent side portion on substrate and top, the

corner casting

8,9,10,11 that has known I.S.O, these corner castings are spaced apart with the distance of 12.2m (40 feet) along the sidepiece of freight container, so that make top corner accessory 8,9 be positioned at substrate corner casting 10,11 tops respectively vertically.

In each end of freight container, also be provided with a framework F, this framework F is installed on the vertical supporting upright post S by hinge H up and down, and to form a triangular arrangement, a strut T is installed on this vertex of a triangle pivotally.

Shown in close or carry the position, the upper arm of strut T and framework F aligns, and its end is releasably secured in the substrate 2 of freight container at connection part 20 places.In this structure, when freight container when corner casting 8,9 raises up, strut T and framework F go up the upper arm that aligns with it and are tensioned, and bear more multi-load than supporting upright post S.

As in the accompanying drawing 3 clear see, framed structure F is by hinged by this way, be its load/unload position (as shown by arrow A) that can open from the carrying position arrival of closing around a vertical pivot ROT13 5 degree, thereby form an inlet that is used for freight container 1 is carried out the sidepiece loading and unloading.As shown in accompanying drawing 3, strut T can swing around horizontal pivot a, comes such as on the underarm that relies on framework F.

Still as shown in accompanying drawing 3, top 5 is strengthened by the back timber 12 of a basic horizontal, and this back timber 12 is that to bear the eccentric moment that takes place at I.S.O. top lift accessory place necessary.The reason that this eccentric phenomena takes place is that the long column (certainty) of 12.2m (" 40 feet ") is positioned adjacent to 2.5m wide outer " case shell " (so that allowing inner width to be applicable to two pallets that 1.2m is wide placed side by side).

For freight container 1 is carried out loading and unloading, curtain 7 side direction are drawn back, middle removable column 6 is removed in a known way, and makes framed structure F, T move to the load/unload position of opening from the carrying position.When the loading or unloading EO, make framed structure move to the carrying position, and make it on the blocked correct position in connector 20 places.Removable column 6 is got back to original position, and curtain 7 is closed.

With reference to accompanying drawing 4, show framework F in more detail, this framework F comprises a upper arm f1 and a underarm f2, they extend inwardly to a pivot P from the hinge H that is spaced vertically along diagonal line, pivot P is at the place, summit of symmetrical triangles structure, and this symmetrical triangles structure is formed by framework and vertical support column S.

Close on the carrying position shown, the end of strut T (lower end) is fixed in the substrate 2 of freight container by a connector 20, and gives upper hinge H with the load transfer in the substrate 2, gives I.S.O. corner casting 9 with load transfer thus.Connector 20 can get loose by means of a handle 21, wherein, the blocking device (not shown) of a routine of handle 21 operation, and such connector 20 shown in dotted line swings around pivot P in a perpendicular, until relying on the underarm f2.

Preferably, described blocking device comprises a pin, and this pin can be fixed in the elongated hole 25 on the strut T.Allow substrate 2 that limited deflection takes place like this.

Then, use handle 22 on hinged H, frame mounting outwards to be opened.

This blocking device is such as can being at the blocking device shown in the accompanying drawing 3,4 and 5 of WO99/59899.

Accompanying drawing 5 shows a kind of variant embodiment, and wherein strut T ' extends up to connector 201 places on the top 5 along diagonal line.Shown in dotted line, strut T ' can swing and rely on the upper arm f1 '.

In another kind of variant embodiment, hinge H can be installed on the vertical column at freight container middle part, and strut T can be along diagonal line from framework downwards an end wall towards this freight container extend.
