Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heavy cargo loading device for a ship that is installed on a ship for loading and unloading heavy cargo.

[Conventional technology] Heavy equipment transported by ship f. There are various types of cargo loading and unloading equipment, each with their own advantages and disadvantages, but the typical ones include (a) loading and unloading equipment from the top deck opening by suspending the cargo using a deck crane, etc. installed on the ship; It will be installed on the designated deck of the ship. In the case of landing, the above is reversed.

(b) Automobiles and other self-propelled cargo board the ship from a rampway provided at the stern or side opening, self-propel to a predetermined position inside the ship, and become loaded, and in the case of unloading, the above process is reversed.

(C) For special roll-on/roll-off systems, the quay is usually modified to have a ramp on the land side that meets the ramp for ship surveying, and has a dedicated perspective.

"Problems to be Solved by the Invention" The problems with the above-mentioned loading and unloading device for heavy cargo are as follows: Generally, the slope climbing ability of the ramp is small, which limits the slope angle of the ramp to be smaller than that of a ramp for general vehicles.Furthermore, in the case of a port where the tidal level difference that occurs at low tide and high tide is large, and the absolute height of the water surface and the top of the quay When navigating between ports with different heights, it is difficult to adjust the relative height between the quay and the hull stowage deck by maintaining the ramp inclination angle within the restricted range using the ramp installed on the ship. From the perspective of hull balance, it is impossible to increase the length of the ramp in order to maintain this restriction as much as in the case of adoption.

(b) In order to compensate for the above problem, it is possible to install auxiliary ramp equipment on the quay side, but in the case of an existing quay,
Modification of the quay is nearly impossible as it is equipped with traveling cranes and other equipment for loading and unloading cargo. Furthermore, due to circumstances such as the geographical impossibility of providing a dedicated perspective for docking wooden boats, it becomes necessary to equip all of these facilities on the wooden boat side. Furthermore, when transporting by sea between multiple ports, a large amount of cost is required to remodel or newly construct each port.

(c) There is a demand for transporting cargo in unit I loads from the standpoint of size saving and cost reduction, and this also applies to the transportation of heavy cargo.

However, regarding the transportation of heavy cargo by crane,
A quay crane requires large-scale reinforcement of the perspective surface, and a ship-equipped crane requires large-scale reinforcement of the ship's hull, which increases costs. Furthermore, it is difficult to achieve a large outreach to the side of a small ship using a crane equipped with a wooden ship due to the balance of the ship's hull, such as trimming. Furthermore, when using an overhead crane to move cargo along the ship's length, reinforcing the ship's hull is difficult.

(d) When handling heavy cargo, it is necessary to move the heavy cargo up and down inside the ship by running the transport vehicle itself in order to ensure the stability of the ship, such as ensuring the GM value, which is the standard for ship stability. Equipping a ramp with a small inclination angle, which is necessary for ships, is a problem because it sacrifices cargo stowage space, and this problem becomes more pronounced as ships become smaller.

(e) When the transport vehicle itself moves within the ship to load and unload heavy cargo, a space is required to move the transport vehicle, which reduces cargo loading efficiency.

(f) A rational transportation method has not been established that handles heavy cargo such as steel and coils, which have traditionally been transported by sea, as a unit load.

In view of the above-mentioned problems, the present invention aims to develop a loading device for loading and unloading heavy cargo as a unit load.

[Means for Solving the Problems] The ship river heavy MOI cargo loading device according to the present invention is capable of loading a heavy M cargo loading pallet loaded on a pallet through an opening with a gunwale opening/closing device with the ship's side moored to a quay. A transport vehicle carrying cargo I. in a suspended state enters the hold, and the heavy cargo f! 11 A means for moving and loading the loaded pallet to a predetermined position in the hold, an opening into which the heavy cargo pallet suspended within the width of the wheels of the transport vehicle is inserted into the hold at the side opening position; Lifting lifts 1 to 1 are equipped with a plurality of holding claws that are rotated or uneven by a hydraulic device or the like from the opening edge to hold the heavy cargo loading pallet, and the lifting lifts l are held horizontally by hydraulic cylinders or chain drives. one end of the lifting lift is pivotally supported on the side opening of the ship's side, and the other end, which rotates up and down, comes into contact with the berthing berth to move the carrier between the berth and the ship. This is a heavy cargo loading device for a ship, which is comprised of a ramp, and a movable cart that carries the heavy cargo loading pallet on a base plate equipped with an elevating device and travels to a predetermined loading position in the direction of the ship's ship.

[Function] In the heavy cargo loading device for a ship according to the present invention, loading of cargo is performed by the following general action, and unloading is the reverse of the following action.

(a) Changes in the height of the quay and ramp caused by changes in the tide level or stagnant water during cargo loading, or differences in the absolute height of each berthed perspective, are adjusted to a state where the ramp is almost horizontal or within the allowable slope climbing range for the transport vehicle. The lamp is adjusted by the lifting lift that supports the lamp.

(l)) A transport vehicle that handles heavy cargo loading pallets in a suspended state is moved from the quay over the ramp and boarded while straddling the opening of the lift l.

(c) A plurality of holding claws protrude from the opening edge of the lifting lift 1~, and the suspended heavy cargo loading pallet I is lowered onto the holding claws, and the transport vehicle transports the next loaded cargo. Move the ship backwards toward the quay as soon as possible.

(d) The lamp is rotated and stored inside the ship, and the lifting lift is lowered to the vicinity of the top surface of the movable trolley.

(e) Raise the white plate installed on the mobile trolley using the lifting device, move the heavy cargo loading pallet placed on the holding claws 2 of the lifting lift 1 onto the mobile trolley base plate, and open the holding claws. It is stored inward from the edge so that the pallet loaded with heavy cargo can be inserted through the opening, and the lifting lift I is raised to the level of the quay to transport the next pallet loaded with hanging cargo. Rotate the lamp that is in place so that it touches the quay, and enter the action on page y.

(f) On the other hand, the mobile trolley that has received the heavy cargo loading pallet on the base plate moves to the designated loading location in the direction of the ship's ship, lowers the white board, and places the heavy cargo loading pallet on the loading deck or on the platform. and move it to the lift position to transport the next heavy cargo loading pallet.

By repeating the above steps, the heavy cargo loading pallet 1
