Abstract

PURPOSE:To smoothly perform operations for taking in-and-out of industrial vehicles provided with crawler equipment each rolled on an upper deck, by setting up an elevator inside a hole approximate to the front of a stern engine room, piercing from the upper deck to each of decks. CONSTITUTION:An elevator 11 is set up inside a hole 10 approximate to the front of a stern engine room 8, piercing from an upper deck 5 to each of decks. On the upper deck, industrial heavy vehicles provided with crawler equipment being rolled in are taken inside another elevator 12 whereby conveyance to the inside of the hold takes place. Reversely, delivery operations for them are also carried out. As compared with the conventional one that a slope way connecting intervals between each of decks is installed inside the hole, the taking in-and-out operation in this case is yet more smoothly carried out.

Description

[Detailed Description of the Invention] The present invention relates to a heavy vehicle/cargo carrier, and more specifically, the present invention relates to a heavy vehicle/cargo carrier, and more specifically, the cargo handling of heavy vehicles, etc. can be carried out simultaneously and efficiently in parallel with the cargo handling of general cargo, which is carried out from the hold entrance of a conventional cargo carrier. , concerning safe conduct of transport vessels.

For loading and unloading vehicles onto ships, there is a elm R-
As shown in Figure 1, except for special purpose ships such as automobiles, which have loading docks, conventionally, as with general cargo, a derrick 1 with a hoist or unloading machine is used, and cargo is dumped from the hold mouth 2 or 3. A self-propelled load dumping means with a slope 4 provided therein;
Alternatively, cargo dumping methods using a combination of these methods have been used. Approximately the same means as described above are also used for cargo handling by heavy vehicles such as road rollers and vehicles with tracks.

However, in the case of a heavy vehicle, there is always danger in running it due to its large weight, and especially in the case of a caterpillar multi-heavy vehicle, when descending the slope, the angle of inclination α of the slope 4 shown in Fig. 1 poses a major hindrance. Interruptions in cargo handling due to falling accidents, as well as slow driving to prevent slips and accidents, are among the causes that significantly increase cargo handling time.

In addition, loading heavy vehicles and general cargo at the same time makes it extremely difficult to secure ramp space and coordinate cargo handling in the cargo hold, further accelerating the increase in cargo handling time, which is extremely unavoidable. Close to possible.

Therefore, the total time required for loading is approximately 24 hours, even on a 7,000 ton class carrier ship of this type. In addition, by using the ramp 4, dead waves are likely to be generated in the cargo hold, and due to the angle α at which the ramp 4 contacts the deck, there are many cases where the deck is damaged by the impact and load on the deck. .

The present invention was developed in order to solve the problems of cargo handling in the conventional heavy vehicle/cargo carrier, and provides a carrier that can carry out cargo handling of heavy vehicles simultaneously with general cargo safely, efficiently, and in a short time. It is intended to.

The heavy vehicle/cargo ship according to the present invention has a heavy vehicle elevator casing penetrating through each deck in the forward hold starting from the end of the heavy vehicle self-propelled path on the upper deck, preferably from the forward bulkhead of the stern engine room. The elevator casing is equipped with an elevator for heavy vehicles that can be moved up and down freely within the elevator casing.

With the above configuration, the above objective is achieved by introducing a heavy vehicle that has traveled on a self-propelled path on the upper deck into the elevator casing, transporting it to a desired deck by the elevator, and then loading it into the hold.

Next, one embodiment of the present invention will be described with reference to FIGS. 2 to 5.

FIG. 2 shows a ship having approximately the same main dimensions as FIG. 1, which is equipped with the cargo handling equipment of the present invention. Reference numeral 6 denotes a self-propelled road on the upper deck 5, and heavy vehicles enter the ship via a bridge board 7 that is directly connected to the pier on the ship's side, and travel on the self-propelled road 6.

Reference numeral 8 denotes a stern engine room, and an elevator casing 11 is provided at a position closest to the engine room 8, preferably in a forward hold 10 with the bow side bulkhead 9 of the engine room 8 as a base point.

Inside the elevator casing 11, four elm elevators 12 are provided which can securely place heavy vehicles and which can be raised and lowered freely. The elevator 1 is installed at a suitable place on the upper deck 13.
A winding machine room 14 in which a winding machine for driving the winding machine 2 is installed is arranged.

On the other hand, heavy vehicles are roughly divided into two types depending on their weight: relatively light vehicles L1 are placed in the hold on the upper deck 5 or cover deck 16, and heavy vehicles L2 are placed on the double bottom top plate 15. Loaded into the hold. Therefore, a heavy vehicle entrance/exit corresponding to the above-mentioned loading is provided in the elevator casing 11 of each deck.

FIG. 3 is a plan view of the upper deck 5, FIG. 4 is a plan view of the double bottom top plate 15, and FIG.
indicate the elevator spaces for light and heavy vehicles, respectively.

The loading operation of this transport vessel with the above configuration will be explained. Incidentally, in the case of loading and unloading, the procedure is almost the reverse of that in the case of loading, so the explanation thereof will be omitted.

When loading heavy vehicles, first, these vehicles are driven along the self-propelled path 6 on the ship's upper deck 5 via the bridge board 7, and introduced into the elevator casing through the weight-specific entrance provided in the elevator casing 11. , placed on the elevator 12. Then, by driving the elevator 12, the heavy vehicle L2 is raised and lowered to the double bottom and top plate 15, and the light weight vehicle is raised and lowered to the upper deck 5 or the cover deck 16, and then installed in the elevator casing 11. It is self-propelled into the hold of each deck by weight-specific exits and loaded at the desired location. During this period, general cargo can be loaded from the hold mouths 2 and 3 using a hoist or unloading machine, similar to the conventional cargo handling on a cargo ship (5). It is possible to do both at the same time. Incidentally, the total cargo handling time of the carrier ship equipped with the cargo handling equipment according to the present invention can be completed in only 5 to 6 hours, compared to 24 hours in the case of the conventional ship, and the cargo handling time can be significantly shortened.

As detailed above, the heavy vehicle/cargo carrier according to the present invention has cargo handling equipment from the hold mouth using a hoist or a cargo lift similar to that of a conventional general cargo ship, and a base point located closest to the stern engine room. A Nireita casing is installed in the forward hold, and an elevator that can freely move up and down inside the elevator casing is used to load and unload heavy vehicles into the hold on a designated deck according to their weight. Unlike conventional cargo handling by this type of carrier ship that uses ramps, cargo handling is completely free from interruptions and slip accidents due to ramp damage or slippage, and extremely safe cargo handling is possible. Since cargo handling by vehicles can be carried out in parallel, the total cargo handling time can be significantly reduced (6).
