Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle chassis storage device for three-dimensionally storing a vehicle chassis such as a trailer chassis in multiple stages.

(Prior Art) A large number of large sea containers are unloaded at a port, and the sea containers are transported by a trailer chassis attached to a tractor. After transportation, a storage area is required to temporarily store the empty trailer chassis, and cargo handling at the trailer chassis storage area has conventionally been carried out by vehicles such as forklifts for transferring trailer chassis. The trailer chassis are stacked and stored on the floor.

(Problems to be solved by the invention) In the conventional storage of the vehicle chassis, there is a limit to the number of stages that the vehicle chassis (trailer chassis) can be stacked, and the number of stages is 2 to 3, making it impossible to increase the storage efficiency for the site. As the number of vehicles increases, a larger site area becomes necessary, which poses problems such as difficulty in securing site space in urban ports and other areas where effective use of site is required.

(Means for Solving Problems) The present invention is a vehicle storage device for dealing with the above-mentioned problems, in which a plurality of long guide members are suspended from a structure so as to be able to move up and down and freely rotate. A plurality of pallet locking hooks that are engaged with or released from the pallet by the rotation of the guide member are attached at intervals for storing the pallet, and the pallet locking hooks are attached to the pallet supported by the pallet locking hooks. By providing a plurality of supporting metal fittings that can be engaged or released so as to move forward and backward, the above-mentioned problems are solved by improving the operation performance for storing and unloading the trolley as well as the storing efficiency.

(Function) Advancement, lifting and lowering of each support fitting of the pallet support mechanism.
Through a series of repeated operations such as lowering and rotation of each long guide member and each hook by the rotation mechanism, retraction of each support fitting of the pallet support mechanism, and raising of each long guide member and each hook, the pallet is sequentially moved together with the chassis. A plurality of carts are supported in an elevated manner and stored three-dimensionally in multiple stages, and by repeating the reverse operation, the carts are successively lowered together with pallets and continuously transported.

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 4, and 1 in the figure is a structure, and the structure 1 is equipped with a plurality of elongated guide members via an elevating and rotating mechanism. 5 is suspended, and a plurality of pallet locking hooks 6 are attached to each long guide member 5 at intervals for storing the pallet. The construction 1 is provided with a pallet support mechanism consisting of a plurality of support fittings 3 in contact with hooks 6.

To explain the elevating/rotating mechanism in detail, as shown in FIGS. 1 and 4, elevating devices 8, 8 such as hydraulic cylinders provided below the sides of the structure 1 and moving sheaves 9a, 9a upward and downward, and a plurality of elevating devices 8, 8, etc. sheave group 9
A total of two lifting wires 10 wound around a and 9
, a lifting mechanism 8,...11 consisting of a lifting beam 11 suspended at the upper part of the structure 1 by each lifting wire 10, and 4 arranged at the four corners of the lifting beam 11. A driving device 1, such as a motor, is provided on the lifting beam 11 and rotates each sprocket via one sprocket 15 and the chain 16.
Rotating mechanisms 14, 15, 16 each having a long guide member 5 fixed to each sprocket 15 and each elongated guide member 5 rotatably supported by the lifting beam 11.
It is composed of.

Further, as shown in FIG. 3, the elongated guide member 5 is provided oppositely to the four corners of the pallet 2, and each hook is inserted into the groove of each receiving metal fitting 13 provided at the four corners of the pallet 2. When each elongated guide member 5 is rotated approximately 90 degrees, each hook 6 is locked to the lower side of the receiving metal fitting 13 to support and suspend the pallet 2. There is.

To explain the pallet support mechanism in detail, each of the hooks 3 is fixed to four long support members 20 arranged on four sides of the structure 1 and rotated by a rotating device 21, The width of the support member 20 is approximately
The structure is such that each hook 3 is rotated 90 degrees and moved forward and backward under the four corners of the pallet 2 by rotation, and each hook 3 is fixed to each elongated support member 20 at intervals for storing the vehicle chassis. It is opposed to the lower part.

12 in the figure is arranged at both lower sides of the structure 1 as shown in Figs. 2 and 3, and lifts the pallet 2 in the pallet storage section provided in the lower part of the structure 1 to the lowest support metal fitting 3. It is a lift device.

The embodiment of the present invention has the above-mentioned structure, and its operation will be explained as follows. As shown in FIGS. By rotating the elongated support member 20, the support fittings 3 are advanced under the pallet 2 and supported, and by elevating the sheave 9a by 1 stroke L by extending the lifting device 8, the lifting wire 10 and the lifting beam 11 Insert the lowermost hook 6 together with the elongated guide member 5 into the receiving metal fitting 13 of the pallet 2 through the
The drive device 14 rotates the hooks 6 together with the long guide members 5 through the chain 16 and sprocket 15, locks and supports them on the receiving metal fittings 13, and places the chassis a on the pallet 2 by self-propelling. (See Figure 5A).

Next, the support fittings 3 are moved back from the pallet 2 by rotation of the long support member 20 (see FIG. 5B), and the sheave 9a is lowered by one stroke L by shortening the elevating device 8, and the long guide member 5 is moved away from the pallet. 2. Chassis a
(see Fig. 5C), and lift device 1
2, lift the pallet 2, insert the lower part of the elongated guide member 5 into the pallet 2, advance the support metal fittings 3 under the pallet 2 using the elongated support member 20, and advance the support metal fittings 3 under the pallet 2. (See Fig. 5 D and E), the elongated member 5 is lowered and rotated (see Fig. 5 F), and the chassis a is loaded onto the lower pallet 2 (see Fig. 5 G). The lower hook 6 loads and supports the chassis a together with the next pallet 2, and the previous pallet 2 and chassis a are lifted up and supported.Furthermore, by repeating the above steps, as shown in FIGS. By using pallets 2, a large number of chassis a can be stored three-dimensionally in multiple stages, and it is also possible to store chassis a carrying empty containers b as needed, as shown in FIGS. 1 and 2.

Moreover, the stored vehicle platform a can be carried out by a reverse operation.

(Effect of the invention) In this way, when the invention is used, it is possible to lift and lower the structure.
A plurality of long guide members are hung so as to be rotatable, and a plurality of pallet locking hooks are attached to the long guide members at intervals for lifting and retracting the pallets, and the hooks are attached to the long guide members at intervals for lifting and retracting the pallets. Since the pallet is provided with a plurality of supporting metal fittings that can be moved forward and backward to lock or release the pallet supported by the pallet locking hooks, the pallet can be raised or lowered by raising and lowering and rotating the long guide member. At the same time, the pallet is supported by the movement of the support fittings regardless of the elevation and descent of the long guide members, and the pallet is engaged with the long guide members by the cooperative action of the pallet locking hooks provided on these long guide members and the support metal fittings. This has the effect of making it possible to raise and lower all the pallets that are stopped at the same time, making it possible to quickly and easily store and unload the cart.
