Description

[Detailed Description of the Invention] The present invention relates to a vehicle attitude control device in a multi-story parking lot.

An example of a multi-story parking lot is shown in FIGS. 1 and 2.

Namely, reference numeral 1 denotes a building, which has a carry-in/out work space 2 formed in the center, and a plurality of floors on both sides with this carry-in/out work space 2 in between.

In other words, in the illustrated example, pillar members 3 are erected at appropriate intervals.
The first floor 5, the second floor 6, the third floor 7, and the fourth floor 8 are formed by the beam members 4 passed between these pillar members 3.

There are multiple parking areas (9) horizontally on the 2nd to 4th floors 6.7.8.
Rack) 10 is sectioned.

These parking sections 10 are arranged in a horizontal direction 9 mounted on the beam member 4.
It is composed of a pair of support rods 11 and a plurality of idle rollers 12 attached to these support rods 11.

The parking section 10 on the first floor 5 is divided by applying white lines on the floor.

Car loading pallets 13 are placed on the first floor 5 in the loading/unloading work space 2 on each floor 6. 7. A lifting device 14 is provided which can be lifted to accommodate the 8.

This lift device 14 consists of a drive unit 16 disposed in a recess 15 formed in the floor, a pantograph 17 that performs telescopic vertical movement, and a lifting platform 1B attached to the upper end of this pantograph 17. When the pallet 13 is lowered to its lowest position, the upper surface of the vehicle-mounted pallet 13 placed thereon is flush with or substantially flush with the floor.

Note that the number of lift devices 14 installed may be either single or multiple.

In the loading/unloading space 2, carts 19 which are guided by rails 20 and movable in the horizontal direction 9 are provided corresponding to each of the second and higher floors 6, 7, 8.

According to such a multi-storey parking lot, cars 21 are parked on pallets 13
Then, the pallet 13 is transferred to the cart 19 by being lifted by the lift device 14, and the pallet 13 is transferred from the cart 19 to the desired parking section 10 to carry the car 21. Can be imported.

By the way, the transfer of the car 21 to the pallet 13 is carried out by the running of the defeated army 21, so the pallet 13 is made wide in advance to absorb some lateral displacement during transfer.

This means that the parking area 10 to which the pallets 13 are delivered is also configured to be wide, and therefore the number of parking spaces on each floor relative to the building area is determined by the width of the parking area.

Therefore, the present invention proposes a car attitude control device in a multi-story parking lot that can minimize the pallet width and increase the number of parking cars.

In addition, cylinder devices 60a, 60b, 61a, 6 lb
The levers 62a, 62b, 63a, and 63b constitute a drive wheel gripping device 75.

Next, we will explain the vehicle loading process.

Before the large vehicle 68A enters, the table lifter 31 is at its lowering limit, and the pallet top surface 36a on the turntable 33 is flush or almost flush with the floor top surface 34a.

Further, the traveling frame 40 is stopped at the vehicle stop position 38, and the levers 62a, 62b, 63a,
63b is stored inside the frames 58A and 58B.

Furthermore, the front wheel centering device 73 and the rear wheel centering device 74 are moved back to the positions shown by the imaginary lines in FIG. 5 by driving the endless chinos 50A and 50B to travel in the same direction.

In this state, the vehicle 68A is advanced as indicated by arrow Z in FIG. 3, stopped at the vehicle stop position 38 below the traveling frame 40, and the driver gets off the vehicle with the handbrake applied.

In this case, the rear wheel 69B is connected to the rear wheel centering device 7 as shown in FIG.

In this case, the pressing direction of the front wheel 69A is regulated by the frames 56A, 56B, and the idle rollers 57A, 57
Rotate B.

Therefore, the running of the front wheels 69A is not hindered.

Further, the traveling frame 40 stops at a fixed position upon receiving a signal generated by the detector 70 detecting the front end of the vehicle 68A.

After this, each mechanism on the traveling frame 40 side, that is, the drive wheel gripping device 75, the front wheel centering device 73, and the rear wheel centering device 74, is sequentially operated in the opposite direction to the above, and the rear wheel 69B is landed on the ground and released from centering. .

Then, the traveling frame 40 is moved backward and returned to the vehicle stopping position 38 in preparation for the next vehicle loading.

The car 68A positioned on the pallet 37 then
As the table lifter 31 rises, the pallet 37 is transferred to the cart 19 shown in FIGS. 1 and 2, and then to a desired parking section 10.

Note that the turntable 33 is rotated as necessary when transporting the car 68A.

The above explanation was about rear-wheel drive large cars, but small cars 6
The same applies to 8a or front wheel drive vehicles.

As described above, according to the present invention, by simply stopping the car at the vehicle stop position and applying the handbrake, the front and rear wheels of the car can be centered by the centering device, and At the end of the train, the drive wheel is lifted off the floor by the drive wheel gripping device, and then the car and trolley can be moved together along a fixed path, and the car remains positioned relative to the pallet on this fixed path. Can be placed.

Therefore, the pallets can be made as wide as possible, which allows for an increase in the number of parking spaces relative to the building area.

In particular, according to the present invention, since the entire device operates while being suspended from the rails installed above, there is no need to install bits or other machinery on the floor.

Therefore, it is possible to improve safety and reduce construction costs.
