Description

Be used in particular for the link of the freight container connecting two stacked on top aboard ship
Technical field
The present invention relates to a kind of for the special link connecting the freight container of two stacked on top aboard ship, described parts have the upper connection protrusion of the bottom corner piece of engagement top freight container, and the lower connection protrusion of the angle supporting device of engagement underlying container, described lower connection protrusion has the flange connector arranged with the longitudinal direction side of freight container and the vertical rear wall arranged like this at the dorsal part of the flange connector of lower connection protrusion, make the edge of flange connector and the distance of rear wall be less than or equal to angle supporting device on open the width of elongated hole.
Background technology
DE 102 38 895 A1 discloses link so as mentioned above.
, aboard ship the improvement operation duration that the binding mode of multiple freight container carries out is carried out since place in operation freight container since the possibility of transporting because of its quick goods.Except considering safety problem, also continue to be devoted to the transhipment step of freight container at harbour to accelerate, so that shorten the time at anchorage of boats and ships.This has been related specifically to the freight container be transported on the deck of ship.First manually to lock these freight containers by twistlock, and this on loading container to ship time and unloading (unloading) time all must manually operate.This not only time-consuming and also above deck loading container time also need alongshoreman on the scene, under therefore forcing it to rest on the goods of suspention.In addition, the surface on freight container top that must walk of alongshoreman unusual cunning under adverse weather situation.Therefore this constitutes great risk for alongshoreman, to such an extent as to once to forbid that alongshoreman stayed in the nineties be the port area of ship loading freight container.
Semi-automatic twist lock (Semi Automatic Twistlock-SAT) achieves and improves safety for alongshoreman and accelerate the first step of the container transshipment at harbour.When the freight container of top is loaded on underlying container, semi-automatic twist lock can connect automatically, so that the freight container of stacked on top can be firmly connected to each other.In order to unload containers must carry out these semi-automatic twist locks of manual unlocking by alongshoreman.This is very safe for alongshoreman, because carman people just can arrive in harbour at ship, before hanging freight container from deck pull-up, just opens and all needs the twistlock of the freight container of unloading and leave ship subsequently.Therefore alongshoreman no longer needs and rests on below the goods of suspention.However, manual releasing twistlock is still very time-consuming.
By starting DE 102 38 895 A1 mentioned above, create a kind of fully automatic twistlock (Fully Automatic Twistlock – FAT), this fully automatic twistlock fully automatically can engage freight container when not only freight container is loaded into underlying container above handle, and also can fully automatically untie when unload containers.Handling employee only needs to hang before on boat deck freight container is drawn, above harbour loads fully automatic twistlock freight container bottom corner piece in, and, after freight container is hung from boat deck pull-up, at harbour, twistlock is unloaded.
Being locked in the freight container that why can connect stacked on top in sea-freight safely according to the full-automatic twisted of DE 102 38 895 A1, is because the flange connector of its side setting.This fully automatic twistlock is based on such understanding: jolting of boats and ships causes the impact of normal acceleration hardly on freight container, therefore have little or no freight container working tension.In fact, very large normal acceleration can be produced when ship shakes.This can between the freight container of two stacked on top to a side action pressure (pushing away side) to another side action pulling force (drawing side).Due to the design of fully automatic twistlock, can stop on the container level direction of stacked on top at the twistlock of pressure side setting and mutually slide.Thus, can determine can not unclamp connection at the flange connector of the twistlock drawing side to arrange.But, up freight container in harbour by hoisting crane pull-up time, can on four twistlocks whole working tension, twistlock may be untied thus.
However still worry, specifically pile case position at some, such as, at front gulf or back bay, under given conditions, may pulling force be produced to whole four twistlocks and therefore less desirable unblock occurs.In order to avoid this situation, propose two relative flange connector fully automatic twistlocks (DE 20 2,004 017 252 U1).Fig. 3 of its file shows a kind of fully automatic twistlock of such design, and the differing heights of twistlock is provided with two flange connectors.When which results in connection and untie twistlock disadvantageous " Z-shaped motion ", because this may cause the situation catching on/block in loading process or uninstall process.
Summary of the invention
The technical problem to be solved in the present invention is thus, and improvement starts mentioned that link above, makes it safely the freight container of two stacked on top be coupled together under the effect of simple tension and prevents " the Z-shaped motion " when connecting and disconnect.
In order to address this problem, the feature according to link of the present invention is, lower connection protrusion has the groove that flute profile extends through lower connection protrusion total length at rear wall place.
Link according to the present invention is just constructing as according to the fully automatic twistlock of DE 102 38 895 A1 substantially.The space of channel shaped is just provided with at the rear wall of twistlock.Thus, connection and just can not produce " Z-shaped motion " when disconnecting.If draw the flange connector of side under various safeguard procedures or skid off from affiliated corner fittings, that is, spin off from opening after elongated hole edge of corner fittings, the freight container of top can on underlying container on even keel with flange connector slide, namely to the direction of groove to the opposite sense in direction.Thus, above hold elongated hole and flange connector opposite side edge can with this engagement, thus link can not be disconnected completely.The freight container of top remains thus with the freight container of below and is connected.Therefore link according to invention has certain emergency protection attribute.
Extra flange is defined at the dorsal part of flange connector due to groove.This flange should have the shoulder of outside declivity.When the edge that thus avoid elongated hole in the process of unload containers inserts in groove unintentionally, lower connection protrusion catches on the elongated hole of corner fittings.For this purpose, this oblique shoulder does not need as the oblique shoulder of flange connector flat.Therefore, this oblique shoulder can be larger than the angle between the oblique shoulder of flange connector and antetheca with the lower angle being connected the rear wall of protrusion.Due in manufacturing process, particularly preferably, the oblique shoulder of flange is made to flush with the lower inside face being connected the handle cavity of protrusion.Because link is all made up of cast steel usually, and mold is simplified due to the oblique shoulder flushed.
At the another side that extra flange is contrary, namely towards on connect the one side of protrusion, according to improvement of the present invention, defined the sideline of groove by lead-ingroove.If groove plays a role in the above described manner or the edge of elongated hole enters unintentionally groove (this reason may rocked at harbour due to blast or freight container and occur) when the angle supporting device making link with lower freight container is connected, can be ensured by lead-ingroove that link (again) arrives on its connection location.
Accompanying drawing explanation
Next, by reference to the accompanying drawings shown in embodiment the present invention is further described.Wherein:
Fig. 1 shows the front elevation of the link with described inventive features;
Fig. 2 shows the lateral plan according to the link shown in Fig. 1.
Detailed description of the invention
