Abstract

A fabricated hinge, for mounting a folding (support) post (14) upon a platform base (11) of a collapsible f latrack container (10), features opposed f langes (27, 28), with differential flange depthsto interface with a diversity of mounted post size and attendant tension or compression loading, whereby a common hinge format suits a diversity of mounted post and loading conditions.

Description

The standardised hinge that is used for flat rack container

Technical field

The present invention relates to be used for the so-called collapsible flat rack container of freight transportation and storage.

Background technology

In general, this flat frame comprises the rectangular platform pedestal with collapsible post and/or end wall.

Post is disposed in corner usually, as angle newel post.

In other words, middle standing pillar can be positioned at the inboard of flat frame pedestal span.

By hinge post and/or wall are installed on the pedestal.

(a fixing) hinge components can be fixed on the platform base, and another (movable) hinge components is fixed on post or the wall.

Suppose that hinge can be by the fixed hinge element of mutual connection and movable hinge components locking, post and/or wall can be used for piling up and erect other container when stand up position so.

In case the hinge release, post and/or wall be collapsible to get off and is positioned on the platform base straightly, so that compact, economical storage and transportation.

There is the flat frame of various types of foldables,, comprises length or (vertically) span of 20 feet and 40 feet to meet the different needs.

Compare with for example 20 feet span, the flat frame of bigger (for example 40 feet) span requires much bigger the platform base degree of depth and intensity.

Similarly, post and end wall size can reflect the geometry and the requirement of strength of different flat framves.

Hinge improves

Therefore hinge must be fit to specific post and base construction.

Itself can not adapt to different requirements traditional hinge structure.

Elongated corner post

A requirement for 20 feet flat framves is very elongated corner post, to be used in the inserting side opening maximization of (unhinderedly) goods access and placement.

Firm corner post

In the flat frame type of another kind, may need firmer and thereby the bigger corner post of volume, to resist high pushing force, perhaps satisfy the intensity or the rigidity requirement of other increase.

Demand forecasting

Owing in suitable flat frame small market, have these dissimilar hinges, be difficult to expect and make or lay in any of many hinge types.

Nonstandardized technique

In addition,, on making, can not realize large-scale production, so they are more expensive because hinge is not standardized, and can not the stock and punctual delivery.

Production cycle

Therefore when adjusting anchor clamps and introducing different materials, may prolong the production cycle of producing significantly for the hinge of new flat frame order.

The universal hinge structure

Thereby, enough by force with satisfy the harshest requirement and with the supporting universal hinge structure of the pedestal of any rational size and corner post be desirable.

Prior art

In PCT/GB2003/000146-WO 03/062100, the applicant has disclosed and has a kind ofly made post be installed in assembling hinge on the flat frame by compound opposing flanges, middle pectoral plate and support component being used to of constituting.

Considered between the post element of hinge and suspension the particularly positioned opposite between the hinge and column flange interface.

But hinge is decided on environment.

Summary of the invention

One aspect of the present invention is the versatility of hinge structure or hinge components part, is used for adapting with multiple hanging column size and the integrated of platform base.

Another aspect of the present invention is the compliance at the hinge of the flat frame that suspends in midair from the upper end of support column, and particularly its material (weight) configuration is with bending load and the subsidiary shear stress of dealing with post and hinge.

According to an aspect of the present invention, the hinge that has opposing flanges and a middle pectoral plate is configured to support mutually with flanged hanging element.

According to a further aspect in the invention, standardized post is installed the variation that hinge is configured to adapt to column dimension, and passes through the interface and the load distribution of the formation between each element (for example flange and web), and hinge and post are strengthened mutually.

Therefore the hinge that is made of opposing flanges and middle pectoral plate can have the flange profile, to produce shoulder, is used for multiple hanging element span.

In a kind of specific structure, be used for as the folding newel post of flat rack container and/hinge of the hanging element of wall comprises: one is used for fixing the element on the hanging element and is used for fixing another element on the pedestal, these elements pivot ground connect, can lock (mutually), and an element is strengthened by suspended structure (mutually).

Mutual reinforcement-flange is also put

Can by corresponding flange and web in articulated constuction and put, come the mutual reinforcement of design of hinges element and hanging element.

Depth of flange

And, can make (hinge) depth of flange or cross section be suitable for local load's requirement.

The flange orientation

For " I " type beam (suspension) post part, relative side flange can laterally be located with respect to deck platform, and middle pectoral plate is longitudinally located.

That is to say, can imagine other and arrange, with at specific structure and load.

Hinge axes

Hinge axes substantially along deck platform laterally, and quadrature is by stacked hinge components web mutually.

Hinge is arranged between inner hinge element and the outer hinge components with being offset, to realize the required athletic performance of hinge and hanging column.

Hinge components can be configured to " L " shape framework or plate, and have upright (interior) flank, to form inboard hinge pivot.

Post and/or end wall hinge action can be lifted away from its position with post and/or wall then, and are positioned at the top of platform base deck level.

Similarly, hinged lock can for example interact between the upright plate wing of hinge axes outer fix at inner hinge element and outer hinge components, thus the post that when joint, is held in place and/or the position of wall.

Racking load

Pile up with processing procedure in, post stands cross deflection and shear-type load or flexural stress.

Similarly, (vertically) relative (I section) post and hinge collar stand various compressions and tensile load.

Suspention load

The suspention load that applies between the post that opposite end walls is associated by handling suspender tends to make post and wall to curve inwardly together.

Flange load

" inboard " column flange is through by compression, and " outside " column flange stands pulling force.

Herein " inboard " and " outside " refer to respectively vertically inwardly and outwards towards flange.

Part section changes

The material that is adopted preferably more can withstanding pressure with respect to pulling force, and in this case, the pulling force that section stands may increase, and the pressure that section stands may reduce.

This is in order by material being concentrated on the place that needs overall weight to be descended, and keeps bending hardness and rigidity simultaneously.

Integral post section, relative depth of flange and middle pectoral plate span can be determined by (bending) load of expection.

In principle, same consideration goes for the hinge components profile, is suitable for the demand of the multifarious universal hinge form of post.

Depth of flange

Therefore for the fixing outer hinge components profile of " I " section of web span, require the degree of depth of careful selection opposing flanges.

For the Container Dimensions in the certain limit, given columnae medialis and hinge collar preferably can be born the compressive load that its material more can stand under suspention, and they may reduce on the degree of depth.

[in fact, inboard (post or hinge) flange may be reduced (be attenuation or attenuate), perhaps even fully is omitted, to support or to comply with (hinge or post) flange of corresponding thickening.] neutral (bending) axle

The whole section of post or hinge components has neutral axis under bending, the changeover portion place of this neutral axis between the opposite side of a side of compressing and stretching.

The corresponding opposing flanges degree of depth, relative spacing or middle pectoral plate span influences bending stiffness and this neutral axis is arranged.

The neutral axis reflection section profile separately of post and hinge, and be independently in this sense.

But, for post and hinge integral body, the whole neutral axis of combination appears.

Can calculate for the neutral axis (weight) of each different relative qualification depthes of flange and positioned opposite and arrange or the middle pectoral plate span.

Common flange

Flange on element helps the rigidity of connected another element.

In this sense, can be between the element that connects common flange, perhaps an element can lean against on the flange of another element.

The structure of fixed hinge and variable post span

If the span and the flange of an element (as hinge) are fixed, for standardization, consider by the load of this distribution, allow change in conjunction with another (post) element.

In particular, different post spans can be attached on the fixing hinge components.

Therefore column web can be fixing contiguously with the hinge collar of fixed span distance.

Therefore the post span is not subjected to the restriction of fixed hinge span.

Hinge (outward) flange of thickening

And, in the outer hinge collar of the thickening of opposing tensile load under the suspention even there be not can help under the situation of outer column flange the integral rigidity of hinge hanging column.

Different posts and hinge interface

By careful selection flange dimension and positioned opposite, common " I " ellbeam outward flange element can be connected or merge with " I " ellbeam post section interface of different size effectively.

Support mutually

For mutual support, can design column jacket and hinge collar overlapped or that distribute.

Hinge and column flange

Therefore, the columnae medialis flange of dependence may extend into hinge inclination inward flange or web shoulder, thereby forms two inward flanges side by side effectively.

In conjunction with or all-in-one-piece mixed lateral column and hinge collar keep the outer span standard of container.

For different post width, subsidiary flange spacing and middle pectoral plate span, column flange may extend into different hinge collar or web shoulder contact position.

In fact, it is to be welded on the web of another element by the flange with an element that hinge is connected with post, to realize the overlapping of cross support or to intersect.

Aforementioned movable (outward) hinge components and the hanging column of mainly being applicable to.

Consider similarly applicable to fixing inner hinge element, but different deck beam size and structures provides wider, be used for the reinforcement that is in contact with one another in the degree of depth of deck.

The post section

Though emphasized " I " ellbeam section, different structures also are fine, as the case section, though even in predetermined form, be not so easily to assemble.

Conventional hinge

On the contrary, conventional hinge structures can rely on the banjo fixing butt jointing that loosens that is positioned at post lower surface and external component upper surface simply.

Symmetrical profile increases

Another aspect of the present invention provides by adopting the heavier outward flange degree of depth or section symmetrical posts and hinge section to increase, resisting the tensile load under suspention better,

Different thickness of flange

In a specific structure, can adopt the outboard flanges of thickening is different thickness of flange with lighter medial flange.

Like this, can keep whole section rigidity and neutral axis and arrange, be used for the post and the hinge components of combination.

The neutral axis motion

In addition, for the wideer post at given hinge section, move medially in neutral axis and post inside edge, and given corresponding mixed lateral column and hinge collar keep aiming at, to keep whole container standard span.

And this means the loss of bulk strength, bending stiffness and hardness.

Invalid/unnecessary material in element section

And neutral axis moves the use material that means poor efficiency and resists the load of forcing, and the excess stock volume is positioned at the element section position of the critical compressive load that wherein stands still less.

Standard pivot and stop pin

Adaptable interface between given each flange and the web can be used for different column dimensions with standard pivot and stop pin.

The specific embodiment

With reference to accompanying drawing.

Fig. 1 represents the phantom drawing of typical collapsible flat frame 10, comprises a platform substrate 11, and it has the plate of tamping or base plate 13 (as timber support), is inside folded end framework on their opposite end or says wall 12.

Each end frame 12 has paired angle newel post 14, or says so that it is set between this angle newel post 14, and angle newel post 14 is installed on the platform substrate 11 by hinge 15.

Fig. 2 represents to have the detailed sectional view of the conventional hinge 15 of the post 14 that is vertically locked.

This is the conventional hinge made from known manufacture method, and it has inner hinge element 17 that is connected on the post 14 and the outer hinge components 16 that is connected on the substrate 11.

(be drawn in right-hand side) at the base angle and locate to install a corner casting 37, it has and is used for the canonical form that the obtaining of container, processing and centering are banked up.

Corner casting 37 comprises that one has and is positioned at its outermost and with the cast iron cuboid box in the processing hole 18 of base apertures, in order to what is called " twisting locked " the deriving means (not shown) of acceptance criteria.

The degree of depth of post 14 " d " is complementary with the degree of depth " e " of inner hinge element 17, thereby can weld with the lap-joint of hinge inner part 17 at post 14 easily, shown in hatching 19.

The similar mode of outer hinge components 16 usefulness is welded on the angle foundry goods 37 along hatching 20, to finish this structure.

The inner hinge pin 21 of biasing can fold post 14 around camber line " a ", so that it was fallen on platform substrate 11.

Stop pin 22 is passed in the hole that aligns mutually on the inside and

outside hinge components

17,16, and is folding to forbid post, withdraws from and with its release unless will sell 22.

The hinge component that is presented among Fig. 2 is a kind of flat frame of 20 feet of common ratio.

Similarly, the outer depth dimensions " f " of hinge is in the downside of angle foundry goods 37 and outside between the top board 23 on hinge components 16 outsides.

For 40 feet flat shelf structure, the outer depth dimensions " f " of hinge must increase to " f ' ", with adapt to the bigger platform substrate of the degree of depth 11 '.

Similarly, the corner post degree of depth " d " can be increased to " d ' ", to adapt to the big pressure that may be applied on the flat frame 10

Yet, new corner post 14 and platform substrate 14 ' all inapplicable present inner hinge element 17 or outer hinge components 16 (with respect to hinge folding direction) towards plate 13.

Fig. 3 represents the another kind of structure of inner hinge flange 17, and its shape is suitable for slender column 14, as Fig. 2, and also can receive aptly the post 14 of big (the broad degree of depth/span) '.

(outward) flange 24 and preceding (interior) flange 25 behind the post 14 ' have have a middle pectoral plate 26, to form an overall beam.

(outward) flange 27 and preceding (interior) flange 28 had a middle pectoral plate 29 after inner hinge element 17 had one.

Pivot pin 21 and stop pin 22 keep its effect by web 29, and they have the installation gudgeon that is supported by

flange

27,28 respectively.

Corner post 14 '

flange

24,25 surround or round the span of inner hinge element 17.

Therefore, back (outward) flange 24 overlaps with the front flange 28 of inner hinge element 17.

Similarly, preceding (interior) flange 25 is stacked with the front flange 28 of inner hinge element 17, and extends downwards towards the bottom of flange 28.

By flange 28 is welded on the web 26, flange 27 is welded on the web 26, and preferably also by distance piece 30 is welded on the

flange

27 and 24 that combines, thereby makes the structure of the inner hinge element 17 of post 14 '

reinforcement flange

27,28 and web 29.

In addition, web 29 can end at the intersection of the web 26 on it and the straight line 31.

If corner post 14 ' form by the mode of elongated shape corner post 14, flange 25 can be by 25 ' mode locate, as among the figure approach flange 28 or with shown in the dotted line of flange 28 conllinear.

Therefore, if pivot pin 21 and stop pin 22 can support by corner post 14 or 14 ' apply pressure load thereon, then various corner post 14,14 ' size can be suitable for the compact inner hinge 17 of same form.

The

flange

24,25 of mounted post 14 extends downwards and king size inner hinge element 17, to play invigoration effect effectively.

Fig. 4 represents to have top board 23, the outer hinge components 16 of stop pin 22 and pivot pin 21.

Dotted line represents to be in the vertically locational hinge inner member 17 of (vertically) (post 14).

Line 32 illustrates one and can be the groove 33 that the flat frame in the shallow end holds angle foundry goods 37.

Expansion stool shape part 34 with bottom line 35 has groove 36 (being similar to groove 33), in order to acceptance angle accessory 37.

The darker platform 11 of substrate ' be soldered on outer hinge components 16 and the stool shape part 34.Stool shape part 34 along the line 32 is soldered on the hinge outer member 16 and enters groove 33.

Additional strengthening part can be set, as outer hinge components 16 being connected (by welding) plate 38 to the stool shape part 34.

Platform 11 ' have siding track 39, it comprises that base flange 40, top flange 41 and

flange connector

40,41 are to form the middle pectoral plate 42 of l shape section beam.

Outer hinge components 16 generally includes parallel-

plate

43 and 44.

Plate 44 has the section that is similar to plate 43, but is projected into its top a little, to connect top flange 41.

And stool shape part 34 is connected on the plate 43, can imagine, and plate 44 can stop along its straight line 32, and selectively utilizes plate 45 to be connected on web 42 and remaining substrate 11 structures.

Get back to Fig. 2, inner hinge element 17 is under the maximum stress, and this maximum stress comes comfortable post 14 to affact pressure on the post 14 by top board 23 places.

Inner hinge element 17 must narrow down, and being adapted to pass through top board 23, but is not enlarging on the inboard of platform substrate 11.

So just make cargo space " g " maximization between relative post 14 surfaces.

Therefore, corner post 14 with big slightly degree of depth " d " can be received, although sacrificed cargo space for the additional intensity of pressure, but the degree of depth of inner hinge element 17 " e " can increase, its method is to add massive plate (extra plating), or makes corner post 14 ' extension and the line h-h by top board 23.

Fig. 5 illustrates a kind of structure of utilizing rectangle stop pin or retainer 50 to replace the stop pin 22 of Fig. 2, wherein utilizes " C " shape section (narrow orifice) piece 51 that retainer 50 is supported in the inner hinge element 17, has the heel 52 of fulcrum post 50 on this piece 51.

Piece 51 is connected on the flange 27 by overlap joint connector 54, and in this case, horseshoe of its outer image is welded to connect part 53 optimizations thereby make to be connected on the flange 27, is applied to pressure on the flat frame 10 more to help bearing by corner post 14.

Fig. 6 A to 6C reflects different flange loads and draws in Fig. 6 C and carry out the sketch that suspension cable promotes.

Fig. 6 A and 6B are the sectional drawings along the line x-x of Fig. 6 C that is used for different hinges and cylindricality formula.

Suspension cable 61 utilizes the component of bending force laterally inwardly to draw the top of relative angle newel post 14 together.

This applies tension load on column flange 24 and the relevant hinge collar 27 again conversely outside.

This crooked tension load has increased the tension force of vertical-lift component, thereby produces double tension force effect on column jacket and hinge collar.

On the contrary, inner prop and hinge collar stand the tension force from the vertical-lift component, and opposite with aduncate compressive force.

Therefore, difference and hinge collar load between interior and column jacket have been marked here, this material arrangements advantageous particularly to reflecting.

And the resistance to compression pression of flange material even bigger than bend loading.

That is to say that the hot strength of post and hinge material (normally steel) is less than its compressive strength.

Therefore, in order to increase the degree of depth of

outboard flanges

24,27, can reduce the degree of depth of some

medial flange

25,28.

(reduce actual load) under the situation that does not increase the general construction quality, in order to optimize effect, can rearrange material advisably, this is effectively.

Theoretical neutral bending axis when Fig. 6 A and 6B basis use hinge and hinge to be used in combination with post has separately been expressed above-mentioned this consideration.

The interpolation between

border flange

27,28 is expressed in the position of hinge neutral axis.

Therefore, the hinge fraction with symmetrical flange has neutral axis on its geometric center lines or axis of symmetry.

Fig. 6 A expresses juxtaposed post and hinge, and (again) of the neutral axis that independent hinge and post combine with hinge arranged.

The neutral axis that post combines with hinge relates to all flanges of doing contribution, and represents with

label

25,27,28.

The effect that the neutral axis that combines that the coupled columns span increases is arranged, promptly to inboard (load by compression) flange 25 re-position at 25 ' effect, also be used for the

neutral axis

25,27,28 of mobile phase combination to the inside.

This means that when the inboard quality of (neutral axis) equaled the quality in the outside, the use of material was inefficient, outside quality more jeopardously is subjected to tension load.

In this analysis, outer column flange 24 is ignored by (temporarily), but for total container span of described standard, theoretically, may be subjected to the restriction of outer hinge collar 27.

Here only have the scope of the span increase of post 14, this increase inwardly rearranges by medial flange and causes.

The hinge span fixes according to the demand of the universal hinge structure of the size that is used for different posts 14.

Fig. 6 B represents since increased the outer hinge collar degree of depth 27 ' and reduced the inward flange degree of depth 28 ', so the hinge neutral axis outwards is offset.

The post span that increases makes synthetic neutral axis 25,27 ' 28 ' to bias internal, but still in the outside of former synthetic

neutral axis

25,27,28.

Adopt another kind of mode, interior column flange just is subjected to maximum tension load herein at this along with the motion of the post degree of depth that increases is opposite with the increase gathering of the outer hinge collar degree of depth.

Fig. 6 B represents reduce (a little) of the medial flange degree of depth, does not produce adverse effect.

And increasing the outboard flanges degree of depth can realize by the hinge and the post outboard flanges degree of depth total or that add mutually.

Like this, the thickening outboard flanges 27 of Fig. 6 B ' can be common between hinge and the post.

On the whole, material is set at best place of using, to optimize weight and strength efficiency.

Sum up:

Suspension cable promotes suspention

The consideration that this suspension cable promotes suspention is being arranged the processing of container and to the consideration of column load.

The post bending

The post bending stiffness has reflected section shape and size, from and reflected depth of flange and space,

Neutral axis has reflected the transition wire between bending and the compression load.

The quality that is positioned at the post of neutral axis inboard or hinge (flange or web) is invalid, because they are not made contributions to the opposing tension load.

Utilization is at the easier opposing compression load of the minimal structure of neutral axis inboard.

Standard hinge

Post and/or hinge are applicable to the localised load demand.

Therefore, although the simple chain form is desirable, also can design heavier and than the modification of the hinge of thin.

Therefore, if heavier than another end wall such as an end wall, assemble a movable end door as passing through, rather than tamp passively, then Xiang Guan angle newel post and hinge can be heavy serial modification.

Can design limited standard hinge scope.

This in addition can pass through local strengthening, make with bigger universal component quantity such as, overlapping or double thickness plate.

Layered structure

Utilize this purpose, can design flange and web template, and allow to use layered structure or stacked structure.

This just makes layered structure be repositioned onto higher stress position from lower stress position again, is in order to satisfy the tension force-compression load on the outside-medial flange under the condition that promotes suspention at suspension cable such as this.

Bridge

In order to realize the geometry and the load of hinge-post contact surface, can use a middle bridge-type accessory.

Combination and coupling

When each feasible combination and conversion all can not be used, the different qualities that can select to determine carry out " combination and coupling ", to satisfy particular demands.

In this respect, post can be different, such as between the substrate end, to express each end wall main body.

And the applicant has advised a kind of pair of standard container form, and this form has paired post at each standard span place, and can adopt post suitable, different size.

If use the paired post of co-operate, such as suspension cable or pressure load, then be that aforesaid way is suitable especially with shared.
