The present invention relates to a car deck of a car carrier, which is capable of switching a height position supported by the hull while being lifted by a lift car.

Conventionally, some car decks installed in multiple layers at about 2m intervals in a car carrier are loaded with car deck panels of about 70 to 150 sheets in total in order to load large vehicles such as trucks and buses in addition to passenger cars. It was made possible to divide | segment up and down by the elevating | decreasable card deck, and to elevate with each of the card deck panels by a lifting means.

Conventionally, lifting devices using winches (however, using hydraulic cylinders), wires, and sieves have been used as lifting means, but in recent years, since the device becomes expensive overall and the work efficiency and operability are poor, a dedicated lift is used. Car is used.

That is, as shown in FIG. 14, the car deck panel 102 is lifted by the lift car from the use position shown in the imaginary line to the storage position immediately below the fixed card deck 101 and walked by the hook 160. On the contrary, the panel 102 is slightly raised from the storage position, and then the hook 160 is peeled off through the sieve 164 to the winch 161 and the rope 162 and lowered to the use position.

By the way, the applicant of the present application, in a prior application (Japanese Utility Model Registration No. 59-122363), installs a plurality of support arms on each side edge of two sides of the card deck to be lifted and lifted by a lift car, A liftable car deck of a car carrier is proposed in which each support arm is switchable by a driving means provided on at least one side of a lift car to a support position where the support portion protrudes out the side edge and a retracted position that does not protrude out the axis.

The drive means comprises (1) a hydraulic cylinder connected to each support arm on the card deck side and a hydraulic supply system for supplying hydraulic pressure from the lift car side; (2) turning the operation handle provided on the card deck side to (3) driving the support arms via the link mechanism on the side of the card deck by means of hydraulic cylinders attached to the lift table's elevating table so as to swing in an inclined manner. Used.

In the conventional apparatus of FIG. 14, the number of parts such as the original (or hydraulic cylinder) 161, the rope 162, the sieve 164, the hook 160, and the like that are attached to the hull for each card deck panel is large. Not only are their design and manufacturing costs expensive, they also require a great deal of design and manufacturing work in order to place them at a predetermined position on their hulls, and there are problems such as multiple operators having to perform them jointly.

In the liftable card deck according to the above-mentioned application, room for improvement remains in the driving means for switching to a plurality of support arm support positions and retracted positions.

That is, in the case of the driving means of (1) above, four pairs of hydraulic cylinders are installed on the elevable card deck, and the hydraulic supply system needs to be connected. Therefore, the driving means is very expensive as a whole. This becomes complicated and expensive.

In the case of the driving means of (2), since the handle must be manually operated every time the position of the support arm is switched, it is disadvantageous in trying to energize.

In the case of the drive means (3), the hydraulic cylinder is a mechanism for driving each support arm via a complicated link mechanism, so that the number of parts of the link mechanism becomes large, heavy, and expensive, and the link mechanism Due to the large frictional resistance of the rotating part, the hydraulic cylinder is enlarged, and the spring pushing the support arms is also enlarged.

The liftable car deck of the car carrier according to the present invention is provided with a plurality of support arms at the periphery of the long-term liftable car deck, and can be repositioned to a support position that protrudes the support out of the periphery and a retreat position that does not protrude out of the periphery. In a liftable deck of an automobile carrier, which is mounted on a lifting table of a lift car and is lifted and lifted so as to switch a height position supported on a hull, the support arms are pushed to a support position shaft by a member means, An input member driven by a predetermined displacement upward by an output operation portion of a driving means provided on the elevating table on an inner lower surface side of the center portion of the elevable card deck, interlocked with an input member and upwardly applied to the input member. A horizontal force in which each of the supporting arms is displaced from its supporting position to its rear position A driving force converter mechanism having an output member for converting the driving force is provided, and the supporting arms are interlocked with each other via a coupling mechanism.

In the liftable car deck of an automobile carrier according to the present invention, when the liftable car deck is raised and switched to the storage position, the output operation part of the driving means is supported in the state where the liftable car deck is supported on the lift table of the lift car. By driving the input member of the drive force converter mechanism upward, each support arm is driven to the retracted position via the output member and the connecting mechanism.

Retracting each support arm to the retracted position as described above while raising the retractable card deck with the elevating cable, or the hook retracts each support arm to the retracted position and then raises the retractable card deck to the elevating table.

After the liftable card deck is raised to the upper storage position slightly above, and the drive is released by the drive means, each support arm is switched to the support position by the absent force of the subsidiary means so that the support portion protrudes out of the periphery, and the lift table When lowering, the elevable card deck is supported on the hull side by the support arm to be in a storage position.

The elevator can be switched in almost the same operation as described above even when the card deck is switched from the storage position to the downward use position.

According to the car deck of the car carrier according to the present invention, as described above, the drive means having a simple structure is installed on the lift table of the lift car, and the input member of the drive force converter mechanism is driven upward by the output operation part of the drive means. By driving the output member, the supporting arm is connected to the disengaging position by resisting the biasing force of the biasing means through the connecting mechanism. Therefore, the driving means provided on the lift table of the lift car is disposed to face each other. Can be simplified, and the driving force converter can be realized by a simple structure. As a connection mechanism, a lightweight one made of, for example, a wire or a sheave can be used for a simple, low price and low friction resistance. Effect is obtained.
