Description

  The present invention relates to a mobile deck support device, and more particularly, to a mobile deck support device that can significantly reduce the time of cargo handling work.

  Generally, in a vehicle carrier (PCC: Pure Car Carrier, PC & TC: Pure Car & Truck Carrier), in order to accommodate more vehicles in a limited space, the vehicles are accommodated in a multistage deck and loaded. Often to do.

  FIG. 1 is a front view showing a conventional mobile deck support device, and FIG. 2 is an enlarged side view showing a stopper of the conventional mobile deck support device. As shown in FIGS. 1 and 2, a conventional mobile deck support device is provided with a multistage deck support device inside four pillars, and a deck on which a vehicle is mounted is attached to each support device. Is stored in a deck of stacks.

  That is, the deck support device is configured by installing a stopper 2 that rotates about a rotation shaft 21 on the inner side surface of each column 1 installed inside the ship (see, for example, Patent Document 1). When no other force is applied to the stopper 2, the stopper 2 maintains a state where the stopper 2 is tilted toward the inside of the column 1 by its own weight.

  In such a conventional mobile deck support device, the deck 3 loaded with the vehicle is lifted by the lift device, and the deck 3 is loaded sequentially from the uppermost layer to the lower layer. When the deck 3 is lifted by the lift device and passes through the lower stopper 2, the side surface of the deck 3 comes into contact with the stopper 2 and raises the stopper 2. After the deck 3 has passed through the stopper 2, the stopper 2 turns around the rotating shaft 21 by its own weight, falls inward, and returns to the deck hoistway.

In this way, the stopper 2 installed in the lowermost layer repeats the operation of being brought up by contact with each deck 3 and then falling down by its own weight until the vehicle is loaded on all the decks 3 of the upper layer support device. Will do.
However, when the deck 3 is loaded and unloaded, the upper deck 3 cannot come down because of the stopper 2 that has fallen on the hoistway.

  In order to solve such a problem, conventionally, the wire 100 is connected to the stopper 2 of each layer, and a fixing means for fixing the wire 100 in the raised state is installed at the lowermost layer so that the stopper 2 of the lower layer is a deck. 3 is configured so as not to interfere with the up and down of 3 (see, for example, Patent Document 2).

  As a result, when the uppermost deck 3 is loaded, only the wire 100 connected to the uppermost stopper 2 is unwound, and the deck 3 is lifted by the lifting device in a state where the other stoppers 2 have fallen.

  Since the stopper 2 other than the uppermost layer is pulled and pulled by the wire 100, the uppermost deck 3 rises without any interference, comes into contact with the uppermost stopper 2, raises the stopper 2, and the deck 3 When it further rises, the uppermost stopper 2 is brought down by its own weight so that the deck 3 can be supported.

When the lift device is lowered, the deck 3 is engaged with the stopper 2 that has fallen inside each pillar 1 and is placed on the stopper 2.
Such an operation is repeated to load the deck 3 on each layer, and when unloading, the opposite operation is repeated to perform the cargo handling work.

  The conventional mobile deck support apparatus has a problem in that work efficiency decreases because the work of fixing or releasing the wire 100 for controlling the stopper 2 is repeated every time the deck 3 is loaded on each layer.

  More specifically, an operator who drives a vehicle equipped with a lift device moves the lift vehicle under the corresponding deck 3 to be loaded each time, then gets off the driver's seat and fixes the wire 100. However, there is a problem that the work efficiency is reduced and a lot of time and labor are required for the cargo handling work.
