CONTAINER CATCHING SYSTEM WHICH IS SEA-PROOF

Abstract

A container catching system, which is sea proof, includes a frame with a base on which a container is to be positioned, hinge pins secured to the frame above the base, and arms situated around the base, each arm having an abovementioned hinge pin. Arm portions situated above the hinge pin contact, in the unfolded state, a container to be lowered to guide the container towards the base, and arm portions situated below the hinge pin move outwards when they contact the container, thereby causing at least the top arm to engage the container.

Claims

1. A container catching system which is sea proof, comprising: a frame with a base on which a container is to be positioned, hinge pins secured to the frame above the base, and arms situated around the base, each arm having a hinge pin of the hinge pins, wherein arm portions situated above said hinge pin contact, in an unfolded state, a container to be lowered to guide the container towards the base, and arm portions situated below the hinge pin move outwards when they contact the container, thereby causing at least the top arm to engage the container.

2. The container catching system according to claim 1, wherein neighbouring arms are connected to one another with girders.

3. The container catching system according to claim 1, wherein at least the arm portions located above the hinge pin can be folded such that they are close to the base.

4. The container catching system according to claim 1, wherein the container catching system or the frame can be mounted on a vehicle or a vessel.

5. The container catching system according to claim 1, wherein the container catching system comprises electrical, mechanical, electromechanical, pneumatic or hydraulic actuators, which are connected to the arms for hinge movement of the arms, and which may or may not be sensor controlled.

6. The container catching system according to claim 1, wherein the arms are of different length, and the arms on the input side, along which containers pass over the base, are lower than the other arms.

7. The container catching system according to claim 1, wherein the container catching system also comprises one or more arms which are fixedly, yet removably, arranged around the base.

8. The container catching system according to claim 7, wherein the one or more arms arranged along the base have end portions which are bent outwards above the base.

9. A method, comprising: using the sea-proof container catching system according to claim 1 to hoist containers, including rescue containers for personnel or other applications, sea containers and/or service containers, on or from board a vessel provided with the container catching system.

Description

[0015] FIG. 1 shows an embodiment of the system according to the invention comprising hinged arms;

[0016] FIGS. 2a and 2b show possible subsequent positions of a container lowered between the arms; and

[0017] FIG. 3 is a side view of the system according to the invention, wherein the container is positioned on the base.

[0018] FIG. 1 shows a container catching system 1 which is sea proof, comprising arms 2 which can move in the direction of the arrows and in the opposite direction, said arms being secured on a frame 3. Said frame 3 has a base G which is dimensioned such that a container 4 can be positioned on the frame. Around the frame 3, raised portions 5 are provided in which hinge pins 6 can be rotated which form part of the arms 2 which can hinge about the pins 6. Said pins 6 of the hinged arms 2 are located above the base G. Each hinged arm 2 has a top arm portion 2-1 and a bottom arm portion 2-2 which can be rigidly interconnected by means of a controllable latch, not shown in the figures, enabling them to swing about the joint hinged pin 6.

[0019] If the arm portion 2-1, which is located above the hinge pin 6, is in the unfolded state, as shown in FIG. 2a, it contacts the container 4 being moved towards said arm portion, and subsequently it guides the container in the direction of the downward arrow towards the base G. If the shown angle profile 4-1 of the container, i.e., where the walls of the container 4 meet, passes the hinge pin and contacts the arm portion 2-2 located below the hinge pin, said arm portion is moved outwards.

[0020] On the opposite side of the frame 3, one or more short arms 7, shown in FIGS. 1 and 3, are located which are bent outwards and which are fixedly, yet often removably, secured to the frame 3, and which in combination with the bottom arm portion 2-2 guide the descending container. These shorter catching arms 7, which are located on the input side of the containers 4 passing said arms above the base, help to achieve that the arm portion 2-2 is made to move outwards by the descending container.

[0021] The outward moving bottom arm portion 2-1 ensures that the top arm portion 2-1 and eventually the arm as a whole engages, in this case the right-hand side of, the container, so that the container can be positioned in a stable and enclosed manner on the base G.

[0022] FIG. 1 further shows that neighbouring arms 7 are connected to one another by means of girders 8. By virtue thereof, one or more stable fences are formed around the perimeter of the base G, which are capable of taking up relatively large impacts which occur in particular when a container 4 contacts the respective arms for the first time.

[0023] The system 1 is compact if the arm portions 2-1 located above the hinge pin 6 can be folded such that they are close to the base G. By means of the abovementioned latch, the portions 2-1 and 2-2 are disconnected, enabling the hinged portions 2-1 to hinge individually such that they are flat on the frame 3. If required, the frame 3 can be mounted on a vehicle or a vessel, if the portions 2-1 are folded, and subsequently it can be transported in compact form.

[0024] Advantageously, an electric energy supply, or provisions for pneumatics or hydraulics can be dispensed with, because the above described purely mechanical measures are sufficient to make the arms 2 hinge. Depending on the circumstances, however, the container catching system 1 may comprise electrical, mechanical, electromechanical, pneumatic or hydraulic actuators, which are connected to the arms 2 for hinge movement of the arms 2, 2-1, and which may or may not be sensor controlled. In this case, the arm portions 2-2 only have to be cams of switches which, together with other means, control said actuators. And the top arm portion 2-1 can then be hinged individually by the actuator at the command of the cam, which may or may not be depressed.

[0025] The sea-proof container catching system 1 can preferably be used to hoist containers 4, in particular rescue containers for personnel or other applications, sea containers and/or service containers, on or from board a vessel provided with the container catching system.

[0026] If required, well-known corner fittings are provided on the frame 3 to lock the container 4 on the base G.
