Description

[Detailed description of the invention] This invention relates to a gas-tight door for a car carrier.

Car carriers are equipped with gas-tight compartments in case of a fire, except during cargo handling, in order to prevent the spread of fire and improve the efficiency of extinguishing fires. On the other hand, when loading and unloading cars onto a car carrier, the cars must be allowed to move freely through gas-tight compartments.
For this reason, gas-tight doors are provided between each gas-tight compartment so that they can be easily opened and closed.

In conventional car carriers, gas-tight compartments are formed using rampways and rampway side walls, and gas-tight doors are provided at the top of the rampway or, conversely, at the bottom of the rampway. Figure 1 shows a conventional gas-tight compartment.
A gastight door 5 is installed at the top of the rampway 4 between Deck 1 and B Deck 2.
A side wall 6 is provided on the rampway 7 between the C deck 3 and the C deck 3. Because there is such a large side wall 6, the ramp way 4 installed on A deck 1 and B deck 2 is
For automobiles using gas-tight doors, visibility through the gas-tight door opening is reduced, creating an extremely dangerous driving condition.

In addition, because conventional gas-tight doors are installed at the top or bottom of the rampway, when the car passes the end of the rampway, it causes the head-hitting or back-hitting that is typical of cars. There were drawbacks such as fear.

This invention solves the above-mentioned conventional drawbacks by providing a gas-tight door in the middle of the rampway.

This invention will be described in detail below with reference to embodiments shown in the drawings. Figure 2 shows a partial cross-section of the vehicle deck including the gas-tight compartment of a car carrier. 12 is the B deck which is a gas-tight deck, 11 is the A deck which is further below the B deck 12, and 13 is the B deck which is further below the B deck 12. This is the upper C deck. A rampway 14 is provided for communication between A deck 11 and B deck 12, and a rampway 15 is provided for communication between B deck 12 and C deck 13. It is possible to drive vehicles to each vehicle deck. I have to. A gastight door 16 that can be opened and closed is provided between the rampway 14 and the rampway 15 and approximately in the middle of the rampway 14, and the triangular shape is surrounded by the B deck 12, the gastight door 16, and the rampways 14 and 15. gas-tight side walls 17 and 18 are provided. A large opening 20 is formed in the side wall 19 of the rampway 15 other than the gas-tight side walls 17 and 18 described above.

As described above, according to this invention, by providing a gas-tight door in the middle of the rampway, the area of the gas-tight side wall of the rampway can be reduced, and accordingly, large openings are created in the side walls of the rampway other than the gas-tight side wall. The gas-tight door provides good visibility through the gas-tight door, providing safe driving conditions when dispatching vehicles.In addition, the gas-tight door is installed on the flat part of the rampway to prevent vehicles from hitting their heads or backing up. This has the effect of ensuring safety in automobile cargo handling operations, such as eliminating the fear of being struck, and ensuring product quality.
