Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a three-stage parking system that stores automobiles in three stages: upper, middle, and lower.

As a conventional device of this type, there is, for example, a three-stage parking device disclosed in Japanese Utility Model Application No. 181477/1987, which was previously filed by the applicant of the present invention. However, this device requires separate drive devices to raise and lower the upper and lower vehicle-mounted pallets, resulting in a complicated structure and increased manufacturing costs.

The present invention was made to solve these problems, and by making it possible to raise and lower the upper and lower vehicle pallets using a single drive device,
The purpose of this invention is to simplify the structure of a three-tiered parking device and reduce manufacturing costs.

An embodiment of the present invention will be described below with reference to the drawings. In the diagram, 1 is the floor surface where the three-tier parking device will be installed, and 2
3 is the floor of the pit installed below the floor 1 of the pit, 3 is a plurality of front supports planted at appropriate intervals on the floor 2 of the pit, and 4 is the front of the pit installed on the floor 2 of the pit. A plurality of rear columns planted in correspondence with column 3, 5
is a beam that connects the upper ends of these front struts 3 and rear struts 4 front to back and left and right; 6 is a bracket protruding from the inside of the middle part of the front strut 3 and rear strut 4; 7 is a beam on these brackets 6; 8 is a middle vehicle-mounted pallet placed on the rail 7 so that it can run freely; 9 is a wheel installed at the front and rear of the pallet 8;
travels on the rail 7 via the wheels 9. 1
Reference numeral 0 denotes a traveling drive device provided on the pallet 8, and rotation is transmitted to the wheels 9 via a chain transmission 11 as shown in FIG. 2, for example.

The number of vehicle-mounted pallets 8 in the middle stage is one less than the number of parking devices arranged in parallel, or a space capable of accommodating one pallet 8 is provided on the side.

Further, 12 is an upper vehicle-mounted pallet, and 13 is a lower vehicle-mounted pallet.

In the present invention, a lifting drive device (reversible brake motor with a speed reducer) 14 is provided on the beam 5 near one rear support 4 in each of the upper, middle, and lower three levels of automobile storage compartments that are connected vertically. The sprocket 15 is fixed to the drive shaft, and this sprocket 15
While hanging both sides of the chain 16 hung on the
A hook 17 is fixed to one end of the chain 16, and a hook 18 is fixed to the other end.

On the other hand, the hook 17 is attached to the upper vehicle pallet 12.
In addition, a support 20 is installed in one corner of the lower vehicle-mounted pallet 13, and a support 21 is provided on the top of the support 20 to engage with the lock 18. . The length of the chain 16 is such that when the upper pallet 12 is located at the same level as the floor 1 and the lower pallet 13 is at the lowest position, the latches 17 and 18 are connected to the holders 19 and 21. Make them long enough to engage each other.

In addition, in front and behind both sides of the upper vehicle pallet 12,
The cable 23, which pivots the sheaves 22a and 22b and has one end tied to the beam 5, is placed below the sheave 22a, then above the sheave 22b, and then the cable end is connected to the above-mentioned cable as shown in FIG. It is connected to the bracket 6 to constitute a balance device for the front and rear of the pallet 12.

Further, as shown in FIG. 5, sheaves 24a and 24b are pivotally supported on the left and right sides of the rear surface of the pallet 12, respectively, and a cable 25 with one end connected to the beam 5 is attached to the sheave 24a.
After applying it to the lower side of the sheave 24b, apply it to the upper side of the sheave 24b,
Furthermore, the ends of the cables are connected to the bracket 6 to form a balance device for the left and right sides of the pallet 12.

Similarly, sheep 26a and 26b are pivotally supported on both sides of the lower vehicle pallet 13 at the front and rear, respectively.
As shown in FIG. 2, the cable 27, which is tied to the front column 3 above the floor 1, is placed below the sheave 26a, then above the sheave 26b, and then the cable end is attached to the floor of the pit. 2 and pallet 1
Configure the front and rear balance devices of 3.

Further, sheaves 28a and 28b are pivotally supported on the left and right sides of the rear surface of the pallet 13, respectively, and a cable 29 with one end connected to the rear column 4 above the floor 1 is attached to the sheave 28.
After hanging the rope under the sheave 28b, the cable ends are tied to the floor 2 of the pit, thereby forming a balance device for the left and right sides of the pallet 13.

Further, as shown in FIG. 2, hook engaging fittings 30 are provided protruding from the front and rear sides of both edges of the upper vehicle pallet 12, respectively, and a hook 31 is rotated by a shaft 32 on a beam 5 above the fittings 30. A lever 33 is provided between the hooks 31 arranged at the front and back.
The central part of the lever 33 is pivotally supported on the beam 5, the upper and lower ends of the lever 33 are respectively connected to the front and rear hooks 31 via the transmission member 34, and the lever 33 is rotated by a solenoid 35 provided on the beam 5. , the front and rear hooks 31 are configured to be freely hookable to and detachable from the hook engagement fittings 30.

Next, the operation of the apparatus of the present invention constructed as described above will be explained.

Figure 1 shows the state in which two middle-stage vehicle-mounted pallets 8 are moved to the left side of the figure, and the right-hand upper stage vehicle-mounted pallet 12 is lowered to the level of the floor 1, among three sets of parking facilities arranged side by side. be. That is, in this state, a vehicle can enter the upper vehicle pallet 12 on the right side from the floor surface 1 in front, and the vehicle on the pallet 12 can be moved onto the floor surface 1.

In this state, the pallet 12 is held by the hook 17 of the chain 16 engaging with the catch 19, as shown in FIG. maintained by.

Next, to raise the pallet 12, the elevating drive device 14 is driven to rotate the sprocket 15 clockwise in FIG. 3. In this way, the chain 16, the hook 17, and the catch 1
9, the pallet 12 rises. In this case, the upper hook 31 is kept open by operating the solenoid 35, as shown by the chain line 31' in FIG. When the pallet 12 reaches its upper limit as shown in FIG. 4, the drive device 14 is stopped and the lever 33 in FIG. 2 is rotated clockwise by operating the solenoid 35. As shown by the solid line in FIG. 4, the hook 31 is operated to engage the hook engagement fitting 30, and then the drive device 14 is reversed to lower the hook 17 slightly, and the hook 3 is moved into the hook engagement fitting 30. fully engages the pallet 12 to secure the pallet 12 in the upper position.

In addition, in order to lower the pallet 12, once the pallet 12 is slightly lifted by the chain 16, the hook 31 is removed from the metal fitting 30, and then
All that is required is to lower the hook 17 of the chain 16.

In addition, in order to raise the lower on-vehicle pallet 13,
As shown by the chain line 12' in FIG. 3, with the upper pallet 12 held in the upper position, the chain is rotated by driving the drive device 14 to rotate the sprocket 15 counterclockwise in FIG. 1
6. Raise the lower pallet 13 via the catch 21 and the support column 20. And pallet 13 is floor 1
When this level is reached, the pallet 13 can be held at the same level as the floor 1 by stopping the drive device 14. That is, in this state, vehicles on the pallet 13 can be freely taken in and taken out.

In addition, in order to lower the pallet 13, the drive device 14 is driven to move the sprocket 15 as shown in FIG.
By rotating clockwise, pallet 1
3 can be lowered to above the floor 2 of the pit. It goes without saying that the lower pallet 13 is also always held horizontally by a balance device including cables 27, 29, etc.

As mentioned above, the device of the present invention is capable of raising and lowering the upper and lower vehicle pallets using a single drive device, so the number of raising and lowering drive devices in a three-tiered parking device can be halved, simplifying the structure, and The effect is that manufacturing costs can be reduced.
