Description

Demountable stub post

Background technology

We know, allow the goods of container loading superelevation, promptly are higher than container height, and this is by the top decision of bight lifting means.

Have the special hoisting crane suspension of extension arm or stretch suspender and be used for enough reaching the overheight cargo place in addition that freight container grasps and promotes.

Selectively, for a special hoisting crane, we know, can use the bar extension, such as on the strut bar of bight, can enough reach in the scope at the standard hoisting crane extracting, loading and unloading and bracing or strutting arrangement are brought back.

The barre extension is assembled on the folding rod, as in the platform base freight container, need take measures, and extension rod is contained in the base.

Typically, extension and master (base) bar is positioned in the base groove special, specially lengthening together, can not weaken when the such structure of base under the situation of structure to allow like this.

For nonvolatil (welding or bolt) bar extension, except with the whole dismounting of extension rod, have only and carry the folding extension rod of single-piece aboard ship, other is had no option.

The permanent bar extension on the foldable panel frame (flatrack) can not occupy the potential goods space of usefulness when not required.

This means and lack flexibility of operation.

Can separate

When not required, even discerptible, such extension if take on the ship, can bring unhelpful passive burden, if perhaps abandon then can bring logistics deposit problem.

In addition, the detouchable extension adopted traditional twistlock in the past, needed suitable screw-driving instrument in case of necessity.

But, use simple manpower means and instrument, can not tighten traditional twistlock screw effectively, (laterally) load of firmly forcing.

Up to now, the bar extension does not also possess the function that is independent of the base bar.

Interchangeable (Re-Deployment)

Among the present invention, extension is detachable with interconvertible, is located on the platform base as independence (bight) stub post, and it is used for the so low profile load in orthicon road.

For this reason, extension has been equipped with releasable adaptor union, thereby is complementary with extracting, loading and unloading and the bracing or strutting arrangement of standard container.

Summary of the invention

According to one aspect of the present invention, detouchable bar extension (or stretcher) respectively has the fixing device that is installed in one (base) end.

This fixing device can adopt the fixing device of the voussoir driving with mechanical advantage.

Especially, a horizontal removable voussoir (21) can be handled vertically moving of locking tongue (22) of dangling.

Voussoir moves preferably screw drive.

Easily, install and finish, drive by tightening screw with mechanical advantage by the rotating locking tongue in (shaping) hole that is arranged in base erecting device (bottom adapter plate).

Such clamping drives and is installed on voussoir with screw is feature, thus its with have the carrier mutual action of groove to be suitable for the mounting jaw that dangles.

Operationally, the locking tongue at first is inserted in the adjustment mounting groove of a basic bar or pallet bases, and then harmonizes, and promptly rotates with respect to groove, contracts to prevent gyrus lingulais, prepares for clamping action.

In specific structure, clamp the rotation that drives screw and make the tongue withdrawal, up to the downside that touches the plate that limits the substrate mounting groove.

Selectively, bar extension (or extension, down with) can be a feature with shaping antelabium or overhanging flange, to stop bar to rotate when the screw-driving.

Embedding portion of connecting of dangling can be positioned the place that extends laterally of tongue receiving slit, also can be used for stoping bar to rotate when tightening.

In specific embodiment, the bar extension comprises, the elongate tubular body; But, has the position and lock tongue that dangles of outstanding substrate along the carrier or the movable stand of tubular body longitudinal movement; The horizontal position set screw engages with the voussoir of the longitudinal slot that is arranged in carrier, and the rotation of screw makes and can draw voussoir along the screw length direction like this, and mobile carrier is realized vertically moving of bar tongue then.

The bar extension is installed on other bar extension with can being arranged to mutual operation.

Can adopt the constraint connecting piece, for example the tightening screw holding element stops dismounting unintentionally.

Freight container, for example collapsible pallet can be equipped with detouchable bar extension.Such freight container can comprise the customised forming pockets on the platform deck, and hold detouchable bar extension.

In diagram, the extracting of use standard, loading and unloading and supporting base end portion device such as the twistlock in the box casting, can be linked together the flat board of piling up, and are used as the one unit heavy burden and handle.

The specific embodiment

With reference to accompanying drawing

(short column) bar extension (or extension, down with) 10 is made the annex of existing bar 11, shown in Figure 1A to Fig. 1 E, and the annex of making pallet bases 12, shown in Fig. 2 A to Fig. 2 E.

Annex can be made the top (bight) of existing standard and grasp loading and unloading and bracing or strutting arrangement, such as the base erecting device (box casting) 13 with conventional twistlock.

Feature according to bar extension of the present invention portion 10 is at one (descending) end a special clamping device for screwing up to be arranged, to stop relatively moving of extension or extension 10 and (base) bar 11.

Opposite (on) end, bar extension portion 10 disposes extracting, loading and unloading and the bracing or strutting arrangement of standard, for example is used for the extension top gripping loading and unloading bracing or strutting arrangement 18 of conventional twistlock.

Effectively, bar extension 10 is (little) rod units independently, can be installed on any cargotainer 20 that has existing (bight) base erecting device 13.

Yet bar extension 10 is located and latching device owing to having specific (base), thereby different with traditional bar 11.

In some cases, can adopt modularization (modular) method, bar extension 10 is linked together in turn or in series, must safe and reliablely relatively move with prevention although each is connected to each other.

Like this, (short column) bar extension 10 can be installed on collapsible flat board, do not have platform, the open top container 33 of bar and close top freight container (not shown).

Like this, for open top container 33, bar extension 10 can provide the loading space that is higher than the sidewall height or the degree of depth, as shown in figure 10.

Though do not show, for more goods clearance height is arranged, independently bar extension 10 also can be assembled on other bar extension 10 of identical or different total length (span), and makes up in the mode of different (being equivalent to the accumulation total length).

In addition, can between existing end bar 11, assemble end wall/door 14.

In principle, for satisfying the environment needs, (short column) bar extension 10 can provide according to multiple different length, still, 1 foot (0.3 meter) and 2 feet (0.6 meter) specifications think particularly useful.

Major requirement for (short column) bar extension 10 provides in Fig. 1 C, wherein the containerable cargo 15 outstanding height that are higher than existing bar 11.

This can cause the loading and unloading difficulty, makes piling up of similar freight container unrealistic, and undesirable especially when relating to breakables.

Like this, (short column) bar extension 10 has prolonged the height of existing bar 11, with complete holding freight 15, shown in Fig. 1 D.

Such structure allows to adopt standard upgrading equipment 35.

More specifically, shown in Figure 12 A, bar portion extension 10 provides the clearance of goods 15, thus the stretching, extension beam 36 that allows extracting, loading and unloading and bracing or strutting arrangement to carry near crane lifting suspension 35.

(short column) bar extension 10 is configured to catch extension top gripping loading and unloading bracing or strutting arrangement 18 firmly with (laterally) free clearance of minimum, to avoid the horizontal extruding of extended height.

Exceeding highly of (short column) bar extension 10, impose on dull and stereotyped 20 base hinge and end frame 14, and the framework of open top container 33 must be considered this point with additional strain when calculating admissible load.

10 pairs of following situations of (short column) bar extension of more specifically, 2 feet (0.6 meters) are wanted specific design:

15 tons (15,241 kilograms) laterally distorsion (racking) is born in each end 16,

7.5 tons (7,620 kilograms) vertically extruding is born in each side 17,

86 tons (87,380 kilograms) heap is pressed (stacking), and

45 tons of top lift maximum gross weights (WMG) (45,722 kilograms).

Some pallets 20 can be designed to quota and support 2 feet (0.6 meter) bar extensions 10, and when end wall 14 and existing bar 11 fall down to fold into base 12, also can hold (short column) bar extension 10, as shown in figure 11.

The bar extension 10 of 3 feet (0.9 meters) can bear 2/3 the horizontal distorsion power of ISO (racking force).

If (short column) bar extension 10 is not supported in the design of pallet 20 or open top container 33, just may need maybe rope to be arranged extraly aboard ship, thereby along the guide box rail with freight container be placed on the deck below.

(short column) bar extension or stretcher are installed

Notice that (short column) portion bar extension 10 has the branch of right-hand side and left-hand side, it is distinguished by the extension top gripping loading and unloading bracing or strutting arrangement 18 that has right-hand side or left-hand side separately.

For (short column) bar extension 10 is clamped to freight container 20, screw 19 should unclamp to loosen voussoir 21.

Then, locking tongue 22 should be inserted in the top base erecting device 13 of existing bar 11 or pallet bases 12.

Then, whole (short column) bar extension 10 revolved turn 90 degrees, like this:

Locking tongue 22 is locked in base erecting device 13 inside;

Bar extension 10, extension top gripping loading and unloading bracing or strutting arrangement 18 is consistent with 16 orientation, end;

The side 17 of freight container 20 outwardly, and is the same with relevant iso standard regulation.

Then, the back side 23 of base plate 24 should be aimed at the back side 25 of the top base erecting device 13 of freight container 20.

Then, screw 19 is tightened, simultaneously, sighthole 26 is to guarantee that locking tongue 22 enters into clamped position smoothly.

When tightening screw 19, optional overhanging flange (side plate) 32 on the base plate 24 and shaping antelabium (edge antelabium) 31 (seeing Fig. 5 C) effect are to stop stub post 10 moving relative to base erecting device 13.

Plate 24 with in connect portion's (inboard lip) 37 (seeing Fig. 7 A to Fig. 7 E) and engage, only when bar extension 10 rotates into its latched position, in the portion of connecting just extend into downwards in the inverted draw cut of base erecting device 13.

Like this, connecting portion 37 in also can stop the rotation of stub post 10 and move.

In case clamp, locking tongue 22 is in abutting connection with the top of base erecting device 13 (be positioned at quadrature inlet slot 39 around).

This adjacency has stoped the rotation of (short column) bar extension 10, and like this, it can not unclamp itself.

After screw 19 was tightened fully, by the hole 28 that 3 millimeters steel wire 27 or equivalent are passed screw 19 heads 29, the hole 30 on the base plate 24, it can be locked and prevents from oneself to unclamp.

The end of steel wire 27 is screwed in together (using the handle instrument), means that it can not accident unclamp such as pliers.

Repeat above-mentioned steps in all four bights, to obtain extension freight container 20 in full force and effect.

The dismounting of (short column) bar extension

Generally, the dismounting of (short column) bar extension 10 can be finished by carrying out (top) mounting list with reverse order.

But in order to unclamp voussoir 21, it may be necessary applying unexpected impact (beaing) influence when initial, in case no longer tension just can be removed the head 29 of screw 19, thereby impel voussoir 21 to be disengaged.

In case unload lower beam extension 10, should tighten screw 19, and make steel wire 27 still pass hole 28 on the screw 19 and the hole 30 on the plate 24 once more, lose with the part that prevents to unclamp.

In the operation, all four bar extensions 10 should use and preserve together.

According to the present invention, for high manipulation strength is provided under low production cost, bar extension 10 is answered specific design.

They can be locked in the appropriate location reliably, almost do not have free clearance between existing bar 11 or base 12 and bar extension 10.

In addition, the means on the handbook of utilization standard can be at an easy rate with its assembling or dismounting.

Should be noted that although do not show, stub post extension 10 itself can telescopic adjustment, or is assembled by less rod unit.

Bar extension 10 can be assembled on any base erecting device 13, and no matter this device is arranged on the freight container end also is arranged between the freight container end, as shown in Figure 8.

Like this, we can say that the feature that 40 feet (12.2 meters) long freight containers of standard have is, adopts the bar extensions 10 of eight same height, promptly four bars are in the centre, and four bars are at the turning, to support freight container that top two 20 feet (6.1 meters) are grown.

And, the stub post extension 10 that unloads can deposit or pack into the container 34 li of the customization grooves of base 12, as shown in Figure 9.

In sum

Generally, can adopt stub post extension 10 modes of standard module, it has the length of regulation, has location and fixed clamping device separately, and free play minimizes with the extruding of following when guaranteeing to assemble.

Bar extension 10 as the extension module, can or be placed according to predetermined location, installation site, angle, and it has related coding identification mark.

Blocking device is copied existing base erecting device 13, and promptly the configuration of (box casting) device is grasped, loaded and unloaded and support at the angle, such as the standard twist lock device.

The base plate 24 that is positioned at bar extension 10 bottoms provides a handing-over interface, the profiled orifice of having only locking tongue 22 to allow to enter configuration case 13 between bar extension 10 and base erecting device (being the form that the configuration case is installed) 13.

The action between the upper surface of the base plate 24 of adjacency and the locking tongue 22 that dangles of translation or traction voussoir 21 is to realize the relative motion between them.

Combination and matching characteristic

Generally, in rationally feasible concrete structure, can and mate a plurality of characteristics combination with conform (situation).

It is impossible describing each such combination of features.
