A SUPPORT FOR CARRYING LOADS IN THE CARGO ROOM

The present invention relates to a carrier 5 according to the preamble of claim 1 for improving the loading capacity of a container ship.

The invention thus relates to the cargo space of a container ship into which containers are stacked. Solutions with cargo hatches with separate container stacks above and below are known in the prior art. Stacks under the hatches are supported by Twist-10 lock and lashing bar. Such stacking of the container stack by corner clamps and drawbars is so weak that the weight of the container stack must be substantially limited. The ship's cargo carrying capacity is thus limited in relation to space.

In unladen cargo spaces, the number of containers stacked on each other 15 is as high as possible due to the strength of the lowest container. Stacks are supported horizontally on vertical container guides. However, the strength of the current standard container is so poor that the weight of the container stack must be substantially limited to prevent the bottom container from collapsing. The ship's cargo carrying capacity is again limited.

Containers can be loaded into container guides on a flat, substantially container bottom-sized frame. The frame is operated by a crane. When loaded, the frame rests on the ship's structures. Such crane-mounted frames form a substantial disadvantage to the ship's carrying capacity in large sizes and slow down the handling of 25 cargoes.

It is an object of the invention to provide a bracket which is capable of withstanding high vertical and horizontal forces in its V. The carrier according to the invention is characterized by the fact that the carrier housing is fixed to the hull structure of the ship 30 and that the carrier housing and the swiveling piece are substantially similar in their mutual contact surfaces so that the movement of the swiveling piece relative to the housing .

A preferred embodiment of the bracket according to the invention is characterized in that the contact surfaces between the pivoting body of the housing are curved.

Yet another preferred embodiment of the bracket according to the invention is characterized in that the bracket is provided with a pivoting mechanism and an actuator for turning the pivot piece.

An advantage of the carrier according to the invention is that the cargo carrying capacity of the ship is substantially increased compared to the known solutions. The structure of the bracket is advantageous because it allows for carrying large loads moving with respect to the bracket so that the support forces can be controlled by small and simple components. It is possible to manually lift the turning piece 10 off / on. The structure is extremely reliable and does not need to be locked in its lower position. The design ensures that the swivel does not damage the load being lifted even if the swivel remains in its lower position.

The invention will now be explained in more detail by way of a preferred embodiment with reference to the accompanying drawings, in which:

Container guides extend to the top of the stack where the containers are supported horizontally by container guides on the ship's hull structures. In the vertical direction, the containers lie on top of each other at their angles.

The vertical load caused by the container stack is led to the ship's structures through the bottom container of the stack. If the load on the lower container becomes too high, the stack can be cut off at the desired position by supporting the top-5 stack at the cut-off point firmly or removably! mechanically lectured in ship structures so that the load on the bottom stack does not carry the load from the overhead stack. Thus, according to the invention, the load-carrying capacity of a container ship can be improved by dividing the container stack into two or more sections by means of the said supports so that the weight of the container stack above the supports is not transferred to the lower stack.

The support 2 according to the invention may serve as a mechanical support (Figures 2 and 3). In Fig. 2, the brackets are in their upper position, whereby loading and unloading of containers 1 from the cargo space is possible without damaging the brackets. 3, the brackets are in their supporting position.

Figures 4-7 show a structure according to an advantageous embodiment of the bracket 2 according to the invention in more detail. The bracket consists of two main components, a housing 2 'and a pivot piece 2', from which the pivoting piece 20 can be pivoted up or removed so that it does not prevent, for example, cargo handling such as unloading or loading in the cargo space. In addition, the bracket 2 may have, for example, a pivot mechanism and an actuator for pivoting the pivot piece 2 '; ; sex. The bracket can be removable or fixed to the ship's structures.

The bracket pivot piece 2 "and housing 2 'have substantially the same contact surfaces" · - ** 25 ". The rotation of the rotating block 2 "with respect to the housing is restricted in all directions except the rotation direction. In Fig. 4, the bracket * · is shown in its up position so that it does not interfere with the unloading or loading of the cargo. In Fig. 5, in turn, the carrier 2 is in its supporting position where it carries the load on it.

Similarly, when the pivot piece is subjected to a horizontal force, the curved foot portion of the pivot piece 35 is supported by a similarly shaped groove in the housing so that the pivot piece cannot move horizontally or rotate.

It will be clear to one skilled in the art that the invention is not limited to the exemplary embodiments set forth above, but may be varied within the scope of the appended claims. Thus, for example, the shape of the housing 2 'and the turning piece 2' may be different from that shown. For example, the leg of the swivel piece and the corresponding body 5 may be shaped differently. The hinge shown in the drawings is not necessary, but the swivel piece 2 'may be a loose component which is lifted into the housing 2'. The carrier can also be used on cargo ships to support other cargo or intermediate decks. 1 »* ·
