Abstract

Decks or cargo, for example, a vehicle loading deck 2 or a device for firmly securing the cargo within the anchoring device to the vessel 1, is an inflatable gas-filled, high-elasticity, And a bag 4. The elastic bags are spaced apart from each other in correspondence with the normal width of the cargo, particularly the cargo of the car (3). After the cargo 3 is placed in the area between the bags 4, the bag is pulled down and fastened to a suitable attachment means at the bottom of the deck. The bag 4 then swells up to a low pressure to expand and surround at least a portion of the cargo 3 from the side of the cargo. Thereby, the bag fills most of the open space on the deck.

Description

Method and apparatus for securing a vessel cargo to a closed deck

European Patent No. 942529 (corresponding to International Publication No. WO96 / 01194) by the present applicant discloses that a high-elasticity, air-filled rubber bag is placed in a free space inside a cargo container to secure the cargo in place in the inflated state of the rubber pack A cargo holding system composed of a highly elastic rubber bag or rubber film is known. In the case of the device according to the claims of the above publication, a rubber bag which is filled in with air from an air pump set mounted in front of the inside of the ceiling portion of the cargo container and capable of controlling and controlling the air pressure so as to prevent the movement of the cargo Is used. The rubber bag has a very high elongation of 5 times or more. Such cargo holding systems can be used in vehicles, boats, aircraft and rail vehicles.

A system for stabilizing a load in a container with a limited volume from GB 2181997 is known. The load is stabilized by placing one or more bags between the wall of the container and the load and / or between the two loads. The inflated bag secures the load by applying pressure against the load.

Japanese Laid-Open Patent Publication No. 52-135187 discloses a system for placing a vehicle on a lower deck of a ship. In this publication, a bag is provided under the deck to be inflated, thereby pressing the vehicle downward and firmly fixing it.

In the case of transporting a cargo, for example a car, on a ship, such as a car or cargo being placed on a large open deck and simply fixing the cargo or arranging large items including vehicles inside the large cargo hold, There is a need to provide stability of the entire ship by not only securing the cargo but also splitting the large surface into smaller zones. This kind of cross-sectional splitting or refinement into compartments can be restricted to areas inside the cargo container or into the cargo deck deck where penetration of water is limited, so that even when the storm is severe, a large amount of water can be prevented from moving across the hull .

The present invention is also applicable to a vehicle deck or a cargo container by a hinged extensible gas-filled elastic bag, preferably provided in the longitudinal direction of the vessel, for transporting the vessel cargo to a closed deck, To a loading deck and a container,

It is therefore an object of the present invention to provide a method and apparatus that can secure a closed deck and cargo to a vessel by dividing the large open space.

This object is achieved by the method and apparatus described in the characterizing part of the claims.

In the present invention, the cargo container or deck that is opened during the unloading operation is divided into small units by a very simple method after the cargo is placed in the cargo position, and the cargo is fixed in a simple and reliable manner. By filling the open space inside the deck or container according to the present invention, water can be submerged only in the minimum space at the time of an accident, and in addition to the fact that the amount of water can be reduced, the moving ability of the water is limited and the stability of the ship is improved .

In addition to this purpose, the present invention provides a number of other advantages.

The inflatable bag according to the present invention provides additional lifting force to the ship in the event of an accident, thereby providing greater lifting force than usual at an emergency and preventing sinking of the ship. According to an aspect of the present invention, the filled gas bag can be filled with the ignition retarding gas, so that a small fire due to the gas blowing due to the rupture of the bag can be automatically prevented.

Another advantage achieved by the present invention is that it automatically locks the cargo without the necessity of using conventional fixing equipment such as chains and straps. This means that while providing considerable rationality in the unloading operation, the cargo can be secured securely to provide a uniform locking effect across the entire surface of the cargo. The cargo is automatically brought into tight contact during transport by adjusting the clamping pressure. Cargo hold can be constantly monitored by the sensor.

Another advantage achieved by the present invention is that it is possible to secure the cargo by inflating the bag even when the container or deck is not fully loaded and to maintain the cargo in a predetermined position on the cargo surface, It is a point.

The device according to the invention can be attached to existing vessels or car ferry vessels without the need for major mechanical modifications to alter the mechanical characteristics of the vessel. The device is very easy to use and does not reduce the capacity of the vessel. By placing the bag in the form of a lattice, the space can be subdivided and can be fixed with respect to the outer edge of the vessel, e.g. the door of the vehicle at the end of the vessel, so that a further fixing effect can be obtained. Such a method of attaching to the inside of the deck drive plate can facilitate precise positioning of the vehicle by allowing the drive lane to be set for the vehicle loading deck.

The invention is explained in more detail by means of an embodiment in the form of a vehicle deck in a car ferry, as shown in the following figures.

Although the drawings of the present invention illustrate the use of the invention in a vehicle deck in connection with anchoring of a vehicle, the present invention may be used in a wider sense, It can also be used for fixing.

1 shows a vehicle loading deck of a vessel or ferry vessel 1, which is collectively referred to as 2. The vehicles 3 indicated by reference numeral 3 on the deck 2 are aligned with each other according to a conventional method. Between vehicles in a row inside the ceiling of the deck there is provided a continuously extending gas-filled, highly elastic bag 4, indicated at 4. For further securing and dividing of the on-board space, a corresponding elastic bag is provided in a direction across the hull, for example in the direction of a reference numeral 5. By providing this type of extendable elastic bag at both ends of the ship, it is possible to further fix the vehicle door and the like.

2 is a cross-sectional view of a vehicle loading deck having a stationary device according to the present invention;

Figs. 3 and 4 are views schematically showing positioning of the elastic bag between the vehicles on the deck. Fig. The elastic bag 4 shows the extended position of the bag fastened by the attachment means 7 to the bottom of the deck between the vehicles. In this position, the vehicle loading deck is divided in the longitudinal direction to prevent water infiltrating into the inside of the ship from being pushed forward and backward between the lateral direction of the ship.

Fig. 4 shows an arrangement according to the invention in a fixed position, in which the elastic bag inflates to secure the cargo, e.g. the vehicle, and also to fill the space between the top and sides of the vehicle. The filling operation is performed in the lateral direction of the vehicle, thereby fixing the vehicle to each other. However, as the inflating action of the bag progresses, the vehicle is fixed in a cushion form by being fixed from above. Only the space under the vehicle becomes free.

5 and 6 show the suspension of the elastic bag 4 and the attachment means. In the inflated position of the bag, the bag acts as a kind of curtain. The lower edge of the bag is designed as a weight load or beam 9 that tightens the bag in a longitudinal direction like a curtain so that the beam 9 is placed in the recess 13 at the bottom of the deck . This is not an absolute requirement since the beam is formed to abut the actual deck floor 6. Each side of the recess 13 is rotated toward each other by suitable drive means to hold the upper or curtain of the beam 9 and hold it in place. Thus, such a fixed position is provided with curtains or walls that are fixed up and down between each row of vehicles, thereby preventing, for example, water from moving in the lateral direction of the ship.

A bag 4 or a curtain rolling up mechanism is shown in Fig. The top of the deck or cargo container is equipped with a rotating roller 11 having a bracket that is driven by a motor to wind up or unroll the bag 4 according to the rotating direction. When the curtain is unwound, the beam 9 provides additional traction in the downward direction. During the unloading operation of the ship, the bag 4 is wound up as shown in Fig. 6, for example. For inflation of the bag, the roller 11 is designed to have a row or more of holes 12 or slots, as shown in the lower portion of Fig. 6 and Fig. Thus, the ends of the rollers are sealed and communicated with the air supply or air inlet of the compressor to supply air through the holes 12 at a low pressure corresponding to a maximum 500 mm water- When the elastic bag is inflated while blowing air into the elastic bag, the elastic bag is in a state of wrapping the vehicle, as shown in Fig. Upon release of the vehicle immobilization operation, the air flows out through the same system. It should be noted that the bag has a high degree of elasticity so that the bag can be expanded more than five times. In addition, the bag must be able to prevent sliding or rupture against the surface by swelling around the surface of the vehicle without sliding on the surface of the vehicle.

In summary, the mode of operation of the present invention is as follows.

(1) In the cargo container, several airtight elastic bags (4) made of high elastic material are mounted. These bags are installed in the middle of the vehicle train.

(2) When the vehicle is outside the ship or near the leanback, the elastic bag 4 is mounted on the hollow tube 11 in a rolled up state (see FIG. 6).

(3) When the vehicle is in the ship, the elastic bag 4 is unfastened and completely fixed to the floor by the attachment means 7 and the beam 9. The bag is inflated by air or gas through the hole of the rotary roller 11. [

④ Therefore, the bag gradually surrounds all the cargoes, and the cargo is fixed while the pressure inside the bag 4 increases.

⑤ The cargo is enclosed by a shell that keeps the air in confinement. There is a pressure difference between the inner and outer portions of the bag that carefully secure the cargo. The pressure is evenly distributed over all surfaces of the cargo. Therefore, the strength of the pressure for fixing the cargo can be adjusted.

⑥ By fixing the bag to the floor and top, the liquid tight compartment is set in the longitudinal direction.

By monitoring the pressure inside each bag by the present invention, it is possible to completely control the fixing state inside the vehicle loading deck or the cargo container. In addition, the vessel provides extra floatation by the bag, thereby providing additional stability in the event of water intruding into the deck or container. At the same time, since the cargo can be fixed without using a fixing strap or the like, the cargo can be fixed more easily and more quickly than before.

The present invention provides a highly adaptable solution. Because the system of the present invention can be attached to existing ferry vessels without major mechanical modifications that would result in a change in the mechanical properties of the vessel. Also, since the fixing method is very flexible, it can be used even when the deck is partially filled. That is, no matter how severe the weather can be, it can be safely used because the remaining empty space can be completely filled with the airbag. Many modifications are possible within the scope of the invention. In addition, the system can be monitored by pressure regulators and sensors that allow the situation on the vehicle deck to be kept constant.
