The lift car table can be raised and lowered by moving it up and down, and this can be held at a predetermined position by one of several stoppers installed at an appropriate height position on the hull or column. The present invention relates to a type of automatic stopper device for liftable car decks.

Conventional technology In a car transport ship,
A vertically movable car loading deck, that is, a liftable car deck is arranged horizontally in several layers, and between them,
In order to maintain an interval approximately equivalent to the height of the automobile to be loaded, each of a pair of opposite sides of each deck is appropriately fixed by several fixed stoppers that are installed in advance on the hull or stanchions. The lower surface near the corner is retained. In this case, the lower surfaces of a pair of opposing sides of each liftable car deck cooperate with these hull-side stoppers so that the hulls or stanchions are supported by previously installed stoppers. A movable stopper is attached so that it can be opened and closed freely, and when the liftable car deck is moved, these movable stoppers are
From the vertical movement path of the car deck, keep it in a position retracted inside the plane contour, and
When the deck reaches the position of the predetermined stopper on the hull side, the movable stoppers are operated so as to project from the outside from the plane contour of the liftable car deck, and these movable stoppers are held by the stoppers on the hull side, This keeps the liftable car deck at the desired height.

In addition, in order to operate the liftable car deck in this way, by placing a mobile lift car that can run on the fixed deck at the bottom of the hold and raising or lowering the table, , This table is also used to raise or lower the liftable car deck.

In this case, the stopper on the side of the liftable car deck is usually formed as a semi-automatic stopper and placed, and when raising and lowering the liftable car deck, manually,
It is common practice to open and close these stoppers.

Recently, instead of this type of semi-automatic stopper, an automatic stopper device has been developed that opens and closes the stopper on the liftable car deck side by linking the rising and lowering motions of the mobile lift car. There is.

Problems to be Solved by the Invention However, the semi-automatic stopper has a drawback that it requires a large number of personnel for its operation, and this drawback becomes more remarkable as the number of liftable car decks increases. In addition, the mechanism for operating the movable stopper installed on the liftable car deck in conjunction with the already proposed mobile lift car is complicated, and its operation is not always easy.

Like In this case, the liftable car deck 10
Has not yet begun to rise, the lower end 11 _{11 of one} leg portion 11 ₁ of each movable stopper 11 installed on it.
Is still under the weight of deck 10. Therefore, even if the operating lever 19 pivots around the shaft 18 so that its one end 19 ₂ rises and is brought into the state shown by the chain double-dashed line in the figure, the other end 19 ₁ is connected to it. The movable stopper 11 cannot be swung via the wire 15. Therefore, the coil spring 25, which is connected to one end 19 ₂ of the wire 15, is moved relative to this end 19 ₂ of the wire 15 and, as indicated by the chain double-dashed line in FIG. And is moved to the position represented by 19 ₂ "in FIG. 6 and tension is created in the spring 25. In this way, the liftable car

Each movable stopper 11 is released from the dead weight of the liftable car deck 10 that has been hanging on it until now, so that the movable stopper 11 is pulled through the wire 15 by the tension applied to the coil spring 25, Therefore, as seen in FIG. 2, the wire 15 turns clockwise and the end portion 15 ₂ of the wire 15 moves to the 6th position.
At the same time as reaching the position of the one end portion 19 ₁ ″ of the operating lever 19 shown by the chain double-dashed line in the figure, at the same time, it takes up the position shown by the chain double-dashed line in FIG. The deck 10 will be allowed to move up and down freely.

Further, as a modification of the embodiment shown in FIG.
The embodiment shown in the figures is also possible. That is, in this embodiment, the coil spring 25 shown in FIG. 6 is omitted, and instead, the operating lever 19 itself is composed of a leaf spring. Also in the case of this embodiment,
When the car deck 10 is lifted by the horizontal table 51 of the mobile lift car 50, the fixed projecting device 53 installed on the table 51 first moves the leaf spring 19, which is the operation lever 19, to the position shown in FIG. It is bent into a state indicated by a broken line in Fig. 1 to store tensile energy inside.
Therefore, when the own weight of the deck 10 hanging on each movable stopper 11 is released as the liftable car deck 10 rises, the pulling energy stored in the operating lever 19 is released, and the operating lever 19 is released. Comes to take the state shown by the chain double-dashed line, and each movable stopper 11
It is turned through 15 to allow the deck 10 to move up and down freely.

Is projected into the inside of the deck 10, but this
It is convenient if the operating lever 19 installed on the 10 is not actuated in any way. However, in the case of the projecting device 52, which is configured as a hydraulic cylinder or the like, it is possible to operate this device 52 independently of the operation of the mobile lift car 50, so that such other openings 20 ′
Need not necessarily be provided.

Further, the projecting device 52 or 53 installed on the horizontal table 51 of the mobile lift car 50 for operating the operating lever 19 is described as a hydraulic or pneumatic cylinder device or a fixed projecting device. However, instead of these, in some cases, it is possible to manually do this.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration and operation, it supports the liftable car deck of a car carrier or the like at a selected height in a freely releasable manner with respect to a hull or a column. This is to provide a suitable one as an automatic stopper for, in particular, in the semi-automatic stopper conventionally used for this purpose, it is possible to completely eliminate the manual operation that was inevitably necessary. The number of personnel required for its operation can be reduced to a minimum, and its configuration is simplified compared to the conventionally known automatic stopper device linked to a mobile lift car. Therefore, the cost for its installation can also be lower. Further, such an effect of the present invention becomes more and more effective as the number of liftable car decks increases.
