Description

The hinge that is used for the Foldable container grillage

Technical field

A kind of general-duty Foldable container flat rack container structure comprises (oblong) platform base, has relative (inside) folding end wall.

Background technology

End wall is bearing between the folding turning post usually, and the turning post itself is installed in rotation on this pedestal.

Two end walls that are folded in downwards on the pedestal are used as compact folding pattern, are used for transporting economically and depositing, and allow to pile up mutually in returning the sky pattern.

This freight container grillage is in use handled easily rambunctiously and is damaged, and does not have topside to help it upright between relative end wall.

This end wall fixes on the every nook and cranny of pedestal with the hinges fixing that can lock.

Under vertical load, suspend the freight container grillage in midair if lack suitable lifting means, just can attempt using the inclination hoist cable by the top corners assembly parts.

Hoist cable trends towards inside pull end wall, and this will make hinge or turning post suffer the danger of et out of order.

Be in commercial need to consider corner stake and hinge reinforcing cheaply, to help to bear this flexural load.

A kind of so more firm freight container grillage uses " I " cross section corner stake, the opposing flexural load that it can be good.

This " I " pillar is installed on the inner hinge part usually, and this inner hinge section construction becomes solid slab.

But the solid slab hinge is very heavy and manufacturing cost is high.

This plate must accurately be holed, to hold pivot pin and this hinged lock is fixed on open position, the upright stop pin of while end wall.

Market trend is that freight container is high more, and corner stake is high more.

Pillar is high more, and is big more near the thrust pressure of this hinge and base for post, so, still need to resist the reinforcing of this power.

Also wish freight container deliver at every turn delivery more capacity weight.

Goods is high more, heavy more, needs the light more freight container grillage of weight.

In the Foldable container framed plate structure, need light, the firm and cheap hinge of this weight.

The specific embodiment

With reference to the accompanying drawings, Foldable container grillage 11 has platform base, and this pedestal has and is folded end wall 13 and is centered around floor surface 12 between the opposite end, and end wall 13 is bearing between the corner stake 17 that hinge is housed.

Have turning assembly parts 14 and substrate 20 in each bottom corners, wherein be equipped with by the hinge inside 18 of pivot pin 19 clampings.

Hinge outside 21 has top (plate) assembly parts 15, and this top assembly parts are passed in hinge inside 18 when relevant corner stake 17 is erected into the upright position.

At the top of each corner stake 17 are top clamping assembly parts 16, and hook 22 is connected in this clamping assembly parts 16, and the end of hook 22 connects an end that hangs hoist cable 23.

The relative edge of hoist cable 23 tilts and perpendicular line " V " angled " A ".

If this freight container grillage 11 is promoted by hoist cable 23, produce horizontal component " H " at the top of assembly parts 16.

This inside 18 and outside 21 at hinge applies a sizable curvilinear movement.

In Fig. 2, hinge outside 21 is by partial cut-out, and to manifest hinge inside 18, it is configured to the L shaped profile of back steel plate.

The representative type thickness of slab is about 60mm.

Partly cut with the top shown in the section drawing (plate) assembly parts 15, to manifest inner 18.

Pivot pin 19 is fixed in pedestal 20.

Corner stake 17 is welded to connect inner hinge part 18 upper ends between opposing flanges 24 and 25 by heavy lift usually.

Shown in the erection position, comprise that outside 21 and inner 18 hinge 26 usefulness locking pins 27 prevent to be folded on the pedestal 20 downwards.

The motion of the rear portion 28 of locking pin 27 obstructions inner 8 and the backboard 29 of top assembly parts 15.

Only retreat when locking pin 27, rear portion 28 can by backboard 29 and make hinge inside 18 with bonded assembly corner stake 17 folding about 90 ° (shrink or overlapping on the limit) on pedestal 20.

When hinge 26 locking and corner stake 17 are erect,, importantly keep the geometric configuration of top assembly parts 16 for need not to regulate and the contacting of normalisation transportation device or other containers.

Importantly pivot pin 19 and locking pin 27 are accurately located with rear portion 28 and backboard 29, rock to stop pillar 17.

Like this, making hinge at inner 18 o'clock, the groove 30, pivot pin 19 of locking pin 27 position with respect to locking pin 27 and groove 30 is being installed, must accurately process, to keep geometric configuration.

But inner 18 heavily about usually 50 or 60 kilograms, this has reduced the possibility of high speed CNC processing.

In Fig. 1, such as the reinforcing of the right corner stake 17 is by increasing its degree of depth to long and short dash line 17 ' obtain most economically.

In Fig. 2, in order to increase the degree of depth of pillar 17, flange 25 be illustrated in the flange 25 that the long and short dash line that changes the position represents '.

Equally, this hinge inside 18 also must increase the degree of depth, keeping intensity, so, front 31 be illustrated in the long and short dash line 31 that changes the position '.

But the intensity increase of this hope has brought undesirable weight and cost allowance.

Fig. 3 illustrates many parts hinge embodiment that the present invention assembles.

Specifically, the inner hinge part that is assembled of slab hinge inside 18 32 replaces.

Described assembling comprises medial flange 33, outboard flanges 34, and the assembling between former 37 placed in the middle and top flange 35 and the base flange 36.

Former 37 can comprise one or more thin plates (that is, ply wood), is welded to connect in

flange

33,34,35 and 36 by periphery.

Corner stake 17 have medial flange 25 ', arranged side by side with inboard hinge flange 33.

For narrower or broad corner stake and hinge, medial flange 33 is easy to be moved into and reorientation corner stake medial flange 25 ' side by side, only need with a suitably big or small former 37.

Inboard biased pivot projection 38 is configured to be installed in the short tube of the joint of

flange

33,36.

In the production, outboard flanges 34 has in advance processing groove 30 thereon, but light many of weight ratio slab hinge inner 18 in this example, so can be fed to the CNC lathe by hand, carries out fast, low-cost and accurately processing.

Pivot proj ections 38 can be processed into very little part on lathe similarly, has the through hole that accurately gets out.

By carefully installing, part can be positioned, be clamped together and craft or automated welding, does not need hinge inside 32 is further processed.

According to the plane of bending stress of Fig. 3, the large-scale flap 18 that former 37 and 60mm are thick is compared can be thinner, such as little of 10mm.

In the structure that the another kind of Fig. 4 assembles, flange 34 can be with rolling web manufacturing, and the wide 30mm that takes advantage of of about 60mm is thick, cuts to certain-length and is formed on 34 ' locate to meet with corner stake flange 25.

Groove 30 can be saved tooling cost by providing at the 41 additional blooms 40 that are welded on flange 34, also provides a bearing 42 to engage locking pin 27.

Fig. 5 A illustrates the top board assembly parts, has lateral opening 44, and its normal width W such as 62.5mm are designed to and known transportation device and connecting device, and for example twist lock cooperates.

When shown in the erection position time, this hinge inside 18 can not manufacture is wider than " W ", and the wide solid slab of 60mm normally.

Fig. 5 B illustrates the hinge inside 32 that assembles according to of the present invention, has

flange

33,34 and former 37.

And outboard flanges 34 must be about 60mm span, and with width W x and top clamping assembly parts 15 by the exterior opening 44 of this hinge, it is Wy that medial flange 33 manufactures width, as shown in the figure.

Be processed into the thick steel plate of 60mm with thin, such as 10mm, former 37, comparative costs height.

In the bending of vertical surface, as bear inclination hoist cable lifting load, the stress amplitude ratio former 37 of the

flange

33,34 of hinge inside 32 is big, supposes that the distance of hinge axis line inside of their long and short dash lines 43 in Fig. 4 is bigger.

Like this, the yield of steel that is used for

flange

33,34 need be than the height of former 37, with the opposing flexural load.

In the prior art, whole single plate 18 must be used the high yield strength steel manufacturing, and insufficient utilization of material further increases cost.

The effective rate of utilization of high yield strength steel plate is good not as the bar steel that uses in the

flange

33,34.

In addition, when the welding quality of the very high yield point steel of needs, the steel plate of this 60mm can not provide.

This can not making and the inner equicohesive hinge of the hinge made from

flange

33,34.

In Fig. 5 B, the width of outboard flanges 34 can not surpass the width W of the 62.5mm of opening 44, because when corner stake 17 was erect, it must pass through this opening 44.

For the reason of geometric configuration, outboard flanges 34 makes such as 60mm is thick.

But therefore medial flange 33 can manufacture broad not by this opening.

Such as, can use with the hinge part of welded plate manufacturing, such as, forge or the as cast part individually makes up or collective's combination, or entirely or partly substitute.

Similarly, whole hinge inside 32 can integrally be forged or cast, and has groove 30,

flange

33,34, former 37 or the

end plate

35,36 of one.

Projection 38 can constitute individually, with being welded to connect on forging parts.

Though described " I " tee section hinge inside 32, on principle, can adopt other forms, for example " U " shape or " C " tee section.

Fig. 6 A and 6B, 7A and 7B illustrate the decomposition diagram of hinge arrangement, have the inside and outside hinge fraction of mutual installation, and the pillar fabricated section is provided, and generally be self-evident, so individually do not describe in detail.

Fig. 6 A illustrates the optional thing of the corner stake of adjacency.

Similarly, Fig. 8 A to 8C illustrates hinged base flange and pivotal mounting variety, and generally is self-evident, so individually do not describe in detail.

Fig. 9, Figure 10 A to 10D and Figure 11 A to 11G illustrate the variety of pillar and hinge fabricated section, and generally are self-evident, so individually do not describe in detail.Use the multicomponent manufacturing, when having only the part hinge to be damaged, can reduce replacement cost.
