DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-layered vehicle storage device in which a plurality of pallets are arranged vertically and each can be moved up and down, and various vehicles are carried in and stored on these pallets. About.

[0002]

2. Description of the Related Art In recent years, the shortage of parking lots in urban areas has become a serious social problem, and there is a strong demand for parking as many vehicles as possible on a limited base. And
In order to respond to this, a multi-layer storage device having a multi-storied storage is conventionally used.

[0003] As such a storage device for a multi-layered vehicle, for example, as described in Japanese Patent Application Laid-Open No. 60-78061, a device for individually raising and lowering each layer of a multi-layer pallet on which a vehicle is mounted is disclosed. There is. However, providing a drive device for lifting and lowering each of a large number of pallets not only complicates the structure but also complicates maintenance and inspection, which is not preferable in terms of equipment costs.

Further, as described in Japanese Utility Model Laid-Open Publication No. 63-119763, a wire rope passing through the upper end of a gantry of a storage is provided along the gantry, and a driving mechanism for winding or releasing the wire rope is connected to the ground side. In some cases, a plurality of pallets are connected to a wire rope to enable multilayer storage. In this example, by providing a sheave at the upper end of the gantry, winding a wire rope around it, and raising and lowering the wire rope by a drive mechanism, it is possible to interlock the pallet in order to raise and lower it, including the drive device The whole equipment is simplified.

[0005]

However, when pallets are added to increase the number of storages, the load on the wire rope increases, and safety measures to prevent the breakage of the wire ropes are important. . For this reason, it is required to attach various safety devices, and it is not possible to expect a significant increase in the number of storages.

When a vehicle is loaded on a pallet and pulled up by a wire rope, the load is applied to the upper end of the gantry from a sheave on which the wire rope is hung.
For this reason, the buckling load received by the columns and the like of the gantry also increases, and it is necessary to increase the overall rigidity of the gantry including the stanchions, including the columns, in order to have a strength that can withstand the buckling load. Therefore, as the number of storage units increases, the site area of the racks also increases, which affects the optimization of land use.

An object of the present invention is to provide a storage device which can store a multi-layered vehicle safely with a simple structure.

Under the guide frames 4a to 4c, the support rod 5 held in the set of the right guide frames 4a and 4b in the drawing is received, and then moved to a position directly below the set of the left guide frames 4b and 4c. Shifter 6 for
Is provided. The shifter 6 includes guide frames 4a to 4c.
And two shift blocks 6b provided between the guide blocks 6a provided in the arrangement direction. The shift block 6b has the same guide space as the cross-sectional shape formed by the guide frames 4a, 4b, includes a roller 6c that rolls the guide block 6a, and can reciprocate by a cylinder 6d.

Below the shifter 6, a guide frame 4 is provided.
A first lifting cylinder 7 for raising and lowering the support rod 5 in the set of a and 4b and a second lifting cylinder 8 for raising and lowering the support rod 5 in the guide frames 4b and 4c together with the pallet 50 are provided. These first and second lifting cylinders 7 and 8 are installed so that their respective axes are coaxial with the two rows of support rods 5, and the stroke thereof is substantially equal to the axis length of the support rods 5.

The main frame 1 has guide frames 4a,
A clamp device 9 is provided for restraining the position of the support rod 5 held in the set 4b. The clamp device 9 includes a clamp arm 9a rotatably provided on a main frame by a pin 9b and a cylinder 9c for rotating the clamp arm 9a.

When the clamp arm 9a is in the posture shown in FIG. 3, its tip enters the clamp hole 5b of the support rod 5, and restrains the vertical movement of the support rod 5. As a result, the upper ones including the support rods 5 located at the lower ends of the guide frames 4a and 4b are shown in FIG.
And held as shown in FIG.

On the other hand, a lock device 10 for restraining the vertical movement of a row of guide rods 5 held by a set of guide frames 4b and 4c is provided on the site. This lock device 10 is provided with a cylinder 10 provided on a gantry 10a.

In the above configuration, when the vehicle 60 enters the central unit in FIG. 1 and rests on the pallet 50, the support rod 5 held by the shift 6 is moved to the guide frame 4b as shown in FIG. , 4c. Then, the support rod 5 is raised by the length of the axis by the second lifting cylinder 8. This allows
As shown in FIG. 3, the hooks 5c of the support rods 5 are hooked on both ends of the pallet 50 and lifted, and the pallet 50 on which the vehicle 60 is mounted moves upward.

After the pallet 50 is lifted, the pin 10c of the lock device 10 advances and fits into the pin hole 5d of the support rod 5, thereby stopping the pallet 50 from moving vertically. Thus, the weight load from the pallet 50 and the vehicle 60 is transmitted to the foundation 2 in the order of the lock device 10, the guide frames 4b and 4c, and the main frame 1.

On the other hand, the support rod 5 held by the set of the guide frames 4a and 4b is maintained in the state shown in FIG. And the next vehicle 60
The shifter block 6b of the shifter 6 is
Then, the clamp by the clamp device 9 is released, and the lowermost support rod 5 is dropped into the shifter 6 side. Then, in the manner described above, the pallet 60 on which the vehicle 60 to enter next is placed is moved to the second lifting cylinder 8.
The support rod 5 is moved upward by the operation of the support rod 5.

When unloading the vehicle 60, the second
After receiving the lower end of the lower support rod 5 supporting the pallet 50 on which the vehicle 60 is mounted by the rod of the lifting cylinder 8 and releasing the lock by the lock device 10, the support rod 5 is gently moved by the second lifting cylinder 8. Lower it. Thereby, the pallet 50 can reach the site level and carry out the vehicle 60. At this time, the lowered support rod 5 moves to the left in FIG. 4 and is held by the shifter block 6b of the shifter 6 which is waiting.

When the vehicle 60 is subsequently carried out,
The shifter block 6b holding the pulled-out support block 5 is returned to the position shown in FIG. 4, and the first lifting cylinder 7 lifts the support block 5 while releasing the clamp by the clamp device 9. As a result, the support block 5 is recovered by the set of the guide frames 4a and 4b. Then, the shifter block 6b is moved again directly below the set of the guide frames 4b and 4c, the support rod 5 for holding the pallet 50 on which the vehicle 60 is mounted is lowered in the manner described above, and the vehicle 60 is carried out.

As described above, the four points of the pallet 50 are received by the four support rods 5, and the four support rods 5
The pallets 50 can be arranged vertically at intervals by utilizing the axial length of the pallet 50, and the vehicle 60 having the pallets 50 in multiple stages can be stored. The row of pallets 50 in the upper layer does not fall unless the support rods 50 holding the lower pallets 50 are pulled out, and the safety is remarkably improved as compared with the case of using a wire rope or the like. I do.

Since the load received by the support rod 50 is transmitted from the guide frames 4b and 4c to the foundation 2 via the main frame 1, a large load is not applied to the upper end of the main frame 1. For this reason, the rigidity against the buckling load can be suppressed to a certain degree, and the weight can be reduced.

FIG. 5 is a side view of a main part showing an example in which supply and recovery of the support rod 5 are performed in another system, and FIG. 6 is a front view thereof.

Inside the main frame 1, one guide frame 11a, 11b having the same sectional shape as the guide frames 4a to 4c of the previous example and forming a concave space is formed.
To form a guide space . And the guide frame 11
b is provided at its appropriate position with a locking device 10 of the same construction as described in the previous example.

Below the guide frames 11a and 11b, a stocker 12 for stocking the support rods 5 and supplying and collecting the support rods 5 to and from the guide frames 11a and 11b is provided. This stocker 1
2 includes two guide blocks 12a that run in the forward and backward directions of the vehicle 60, and a stocker block 12b that is connected to the guide blocks 12a and that can be moved by rollers 12c, and a cylinder 12d that moves the stocker blocks 12b forward and backward. It is provided.

The stocker block 12b is composed of five retainers 1 using the same members as the guide frames 11a and 11b.
2e so that the support rod 5 can be inserted between the adjacent retainers 12e.

Further, just below the guide frames 11a and 11b and below the stocker 12, a support rod 5 is provided.
The lifting cylinder 13 for raising and lowering is provided.

In this example, when the vehicle 60 is placed on the pallet 50, the lifting cylinder 13 pushes up the support rod 5 located at the right end in FIG. 5 from the stocker 12 and sends it out into the guide frames 11a and 11b.
As a result, as shown by the one-dot chain line in FIG. 6, the pallet 50 is raised by hooking on the hook 5c of the support rod 5, and is locked by the lock device 10 at a fixed position.

When the vehicle 60 is subsequently carried in,
By the cylinder 12d of the stocker 12, the second support rod 5 from the right in FIG.
a, 11b until the stocker block 12
Move b. Then, the support rod 5 immediately above the guide frame 11a, 1
By pushing the support rod 5 into the base rod 1b, the lower support rod 5 is raised while the support rod 5 holding the pallet 50 previously raised is raised. This allows
The two vehicles 60 are stacked by two pallets 50, and up to four layers can be stacked in the illustrated example.

When the vehicle 60 is carried out, the rod of the lifting cylinder 13 is protruded upward from the stocker 12 to receive the lower end of the lowermost support rod 5, and the pallet 50 is lowered by lowering the rod. The rod 5 is collected in the stocker 12. In the case of four-tier stacking, the stocker block 12b is
Is moved to the rightmost side and collected from the leftmost stocker block 12b.

In the above example, only the two guide frames 11a and 11b are provided in the main frame 1, and only one lifting cylinder 13 is required, so that the structure is further simplified as compared with the previous example.

[0041]

According to the present invention, the following effects can be obtained.

1) Since the support for supporting the pallet is extended and the pallets are stacked in multiple stages, the rigidity is higher than that of the pallet supported by a wire rope or the like, and the safety is improved.

2) Since it is only necessary to provide a drive mechanism for raising and recovering the support at the lower end side of the main frame, the load on the main frame is reduced, the weight can be reduced, and the maintenance and inspection become easy.

3) Since the row of supports receives the load of each pallet and vehicle and transmits it to the foundation, a large load is not applied to the main frame from the upper end, and the main frame is made large even against buckling load. And the installation area can be reduced.
