Description

Technical Field

[0001] The present invention belongs to the field of ship facilities and relates to an interconnection device between ships and a using method thereof. Background Art

[0002] A ship is a means of transportation traveling on the water surface. The goods and materials of a ship can usually be replenished by docking at the shore, but there is also a need for the interconnection of personnel and items between two ships. The interconnection of personnel and items between two ships is generally achieved through the following several methods: 1. Side-by-side transfer: Two ships are berthed side by side. For example, a supply ship and a warship, a cruise ship and a supply ship, etc., which need to be carried out when the sea conditions are relatively calm. The method is that the two ships are fixed by cables, kept parallel and berthed side by side. An accommodation ladder or a gangplank is erected between the two ships, and personnel or small items are transferred on foot through the ladder. Precautions: It is necessary to closely coordinate the speeds and positions of the two ships to avoid collisions.

[0003] 2. Small boat transfer: When two ships cannot directly approach each other, such as between a large cargo ship and the shore base or when the distance is far. The method is to release a lifeboat or a workboat (such as a motorized small boat, a speedboat), and the personnel / items are first transferred to the small boat and then driven towards the target ship. The ship can lift and lower the small boat through a crane or a slide rail. Typical application scenarios are in cruise ship passenger transfer, island supply, maritime rescue, etc.

[0004] 3. High-line transfer: When two ships keep a certain distance and cannot approach each other, such as during supply between warships or in bad sea conditions. The method is to erect a steel cable or a high-strength rope (high-line) between the two ships, and then use a pulley hanging basket or a special cargo net to slide and transport items along the rope. Personnel can be transferred through a life-saving sling or a hanging cage. The advantage of this method is that it can reduce the risk of ship collision and is suitable for the transfer of heavy materials between ships.

[0005] 4. Helicopter transfer: Used for long distances, emergencies or large ships (such as warships, scientific research ships).

[0006] 5. Crane transfer: Large goods (such as containers, equipment) are transferred between two ships, and this method requires the two ships to approach first.

[0007] 6. Floating device: Short-distance and non-emergency item transfer (such as documents, small packages). The method is to use a waterproof buoy or an inflatable bag to wrap the items and tow them to the other ship through a rope.

[0008] 7. Using a drone to deliver light materials.

[0009] For the high-line transfer method where two ships need to keep a distance, when a hanging basket is suspended on the rope, due to the fluctuation of the sea waves, the downward-suspended hanging basket is very likely to be submerged in the sea water, presenting uncertainty and insecurity. Summary of the Invention

[0010] The object of the present invention is to solve the problem that in the current high-line transmission method between two ships, the way of suspending the hanging basket downward on the rope is prone to submerge into the water with the floating and sinking of the waves, and to provide an intercommunication device between ships and its usage method. By using a cargo basket suspended above the rope, the goods can be prevented from being immersed in the water. Moreover, by making the center of gravity of the cargo basket as close as possible to the guiding rope, and connecting a balloon to the top of the hanging basket with a long rigid connecting rod, the stability of the cargo basket can be effectively maintained by using the lever principle, and the cargo basket can be prevented from tilting during transportation.

[0011] The technical solution adopted by the present invention to solve its technical problems is as follows: An intercommunication device between ships includes two ships. There are columns arranged on the ship decks. A guiding rope is arranged between the columns of the two ships. A cargo basket is slidably arranged on the guiding rope. Towing ropes are respectively arranged between the two sides of the cargo basket and the two ships; The cargo basket is arranged above the guiding rope. A guiding collar sleeved on the guiding rope is fixedly arranged at the bottom of the cargo basket. A base is arranged below the guiding collar at the bottom of the cargo basket. A connecting rod is arranged upward at the top of the cargo basket. The connecting rod is a rigid rod. The bottom of the connecting rod is fixedly connected to the top of the cargo basket. A buoyancy ball is sleeved on the top of the connecting rod.

[0012] After setting up a rope transportation channel between the ships in this device, the cargo basket is designed above the guiding rope. Through the configuration of transported substances and counterweights, the center of gravity of the cargo basket and the base is made as close as possible to the height of the guiding rope. The top of the cargo basket is connected to the buoyancy ball through a long connecting rod. When the cargo basket has a tendency to tilt, due to the center of gravity being close to the guiding rope, the lever arm is small, and the torque generated by its gravity is small; while the lever arm of the buoyancy ball can be determined by the length of the connecting rod, and the lever arm is large. Therefore, the buoyancy ball only needs a small buoyancy to counteract the gravity torque and prevent the cargo basket from tilting. In extreme cases, when there is very little substance in the cargo basket, or even by setting counterweights, the center of gravity of the cargo basket and the base is made lower than the guiding rope, so that the center of gravity of the cargo basket and the base can maintain stability by itself, and the buoyancy ball plays an insurance role. The buoyancy ball can be a helium balloon, etc.

[0013] Preferably, the base and the connecting rod are both fixedly connected to the cargo basket and swing synchronously. The base, the connecting rod and the cargo basket are of an integral structure and tilt synchronously to maintain the effective lever arm of the buoyancy of the buoyancy ball.

[0014] Preferably, one guiding collar is respectively arranged on both sides of the bottom surface of the cargo basket, and both guiding collars are sleeved outside the guiding rope. The guiding collars on both sides are of a circular ring structure, or a circular tube can also be used instead, to ensure that the cargo basket can run along the guiding rope.

[0015] Preferably, one set or more sets of counter-rollers clamped on the guiding rope are arranged between the two guiding collars. The clamping roller structure of the counter-rollers can make the movement of the cargo basket smoother.

[0016] Preferably, two pairs of rollers are provided, and the two pairs of rollers are respectively arranged in abutment with two guiding collar rings.

[0017] Preferably, the connecting rod is a multi-section nested telescopic rod. When the connecting rod is stored, it shrinks to reduce space occupation, while when in use, it can extend into a longer rod shape under the action of the buoyancy ball to extend the buoyancy force arm.

[0018] Preferably, the base can be added or reduced in weight, and is used as both a support and a counterweight at the same time.

[0019] Preferably, a guiding seat is arranged at the top of the column, and a guiding cable hole for the guiding cable to pass through and be positioned, and a towing cable hole for the towing cable to pass through and be positioned are arranged on the guiding seat. The guiding cable winch and the towing cable winch are arranged on the outer side of the column on the deck.

[0020] A usage method of an intercommunication device between ships, using the above-mentioned intercommunication device between ships, includes the following steps: S1, Two ships select positions, keep a distance and anchor. One of the ships fires a javelin at the deck of the other ship to throw one end of the guiding cable and the towing cable towards the other ship; S2, Pass the guiding cable through the guiding collar ring at the bottom of the cargo basket, and respectively tighten the two ends of the guiding cable on the two ships to form a cableway, fix the towing cable on both sides of the cargo basket and tighten both ends; S3, Load materials into the cargo basket, and add or reduce the weight in the base according to the weight of the materials, so that the overall center of gravity of the cargo basket and the base is as close as possible to the position of the guiding cable; S4, Inflate the buoyancy ball so that the buoyancy ball has a certain upward floating pulling force; S5, One end of the towing cable is wound and the other end is unwound to tow the cargo basket to transport between the two ships; S6, After the transportation is completed, deflate the buoyancy ball, and recover the guiding cable and the towing cable.

[0021] Preferably, in steps S3 and S4, the weights of the materials, the counterweight, and the inflation amount are calibrated in advance; when the buoyancy ball is inflated and floats, it drives the connecting rod to extend.

[0022] During the transfer of the cargo basket of the present invention between ships, it always remains above the guiding cable, reducing the possibility of dipping downward into the sea water. At the same time, by controlling the center of gravity of the cargo basket, the force arm of the gravity torque is reduced, and the buoyancy ball can be used to avoid the inclination of the cargo basket with a smaller buoyancy.
