Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator apparatus for a multi-story parking apparatus which is installed inside a parking structure and vertically conveys a vehicle vertically.

[0002]

2. Description of the Related Art There is known a high-rise multi-storey parking system in which an elevator is incorporated in a parking structure on a multi-story floor, and a parking space for housing a vehicle is arranged on each floor of the structure.

This type can be roughly classified into two types. One of them is to arrange parking spaces on both sides or one side of an elevator that vertically conveys a vehicle.The vehicle is loaded on the elevator at a home position on the ground floor and vertically conveyed to a predetermined floor by the elevator. After that, store it in the parking space. Further, the stored vehicle can be carried out onto the elevator, transported to the home position, and taken out.

On the other hand, a large number of parking spaces are secured on each floor, and a truck for horizontally transporting the vehicle is arranged on each floor. By combining vertical transport by the elevator and horizontal transport by the truck, the vehicle can be entered. The goods are to be shipped.

In either case, for safety, the elevator carriage is hung by four wires, chains or other cord-like bodies, and is driven by a drive unit installed above the parking structure. To be done. In addition, a counterweight is usually provided in order to balance with the carriage, and the counterweight at this time is generally disposed on the left and right or the front and rear of the carriage in the hoistway where the carriage moves up and down. .

[0006]

However, according to the prior art, the problem of inefficient space in the parking structure is unavoidable. That is, since the cord-like body that suspends the carriage and the counterweight must be connected to the drive section through an appropriate tensioner device, the carriage and the counterweight are placed close to each other in order to interpose the tensioner device. It was difficult to install and the hoistway had to be made larger than necessary. In addition, if the carriage and the counterweight are brought close to each other in an attempt to keep the hoistway to a minimum space, it is complicated to hang the cord-like body, and the entire structure of the drive unit is unnecessarily complicated. It was

In view of the problems of the prior art, the object of the present invention is to provide the counter weight on the far outside of the parking space adjacent to the hoistway of the carriage, thereby simplifying the structure of the drive unit. An object of the present invention is to provide an elevator device for a multilevel parking device that can maximize the space efficiency of a parking structure.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the structure of the present invention is a drive unit installed on the upper portion of a parking structure, a carriage for loading a vehicle driven by the drive unit, and a counter balanced with the carriage. It is provided with a weight, and the gist is that the counterweight is arranged on the far outside of the parking space adjacent to the hoistway of the carriage.

[0009]

According to the structure of the present invention, since the counterweight is disposed far outside the parking space adjacent to the hoistway of the carriage, the drive unit can be installed above the parking space. Even if the tensioner device is included, there is a sufficiently large space allowance, and it is possible to extremely simply wrap the cord. Further, the hoistway of the carriage and the hoistway of the counterweight can be suppressed to the minimum necessary size.

It is installed on the upper part of. The hoistways W1 and W2 are
It is assumed that the carriage 20 and the counterweight 31 can be raised and lowered to the minimum necessary. A pit W1a is formed below the hoistway W1 for lowering the carriage 20 to a predetermined position (FIG. 3).

In the parking structure B, the pillars B are provided so as to divide the parking spaces S, S ...
6 and B6 are provided (FIG. 2), and the roller rails S1 and S1 of each parking space S are provided with pillar members B6 and B6 on both sides.
It is installed on the girder material B7 connecting the two through spacers S2 and S2.

Now, when there is a vehicle to be parked in one of the entrances B3 and B3, the carriage 20 of the elevator device corresponding to the entrance B3 first rises to the floor where the empty parking space S is located, and then the floor. The empty pallet P is carried out onto the carriage 20 by the carriage T of the
It descends to the home position of L (Fig. 3).

When the carriage 20 stops at the home position, the vehicle can be loaded on the pallet P by self-propelling, and thereafter, the carriage 20 reaches the floor of the parking space S where the empty pallet P is pulled out. Is conveyed vertically. Therefore, the truck T on that floor is a pallet P.
At the same time, the vehicle can be horizontally transported and stored in the parking space S, and the warehousing operation of the vehicle can be completed.

On the other hand, when the vehicle is to be unloaded, the carriage 20 of one of the elevators moves up to the floor where the designated vehicle is located, while the carriage T on that floor carries the designated vehicle together with the pallet P from the parking space S. Then carriage 2
It is conveyed horizontally to the front of 0 and loaded on the carriage 20. Therefore, the carriage 20 can vertically convey the designated vehicle to the home position together with the pallet P, and if the carriage 20 stops at the home position, the vehicle can self-propelled.
It should be noted that the empty pallet P after being unloaded in this way
Can be used as it is when the next vehicle is loaded.

When the carriage 20 moves up and down in the hoistway W1, the counterweight 31 moves up and down in the hoistway W2 in the opposite direction. Further, at this time, since the tension sprocket 14a is provided, the horizontal distance d can be set above the parking spaces S, S ... Adjacent to the hoistway W1 (FIG. 2), so that an unnecessary dead space is created in the parking structure B. It never happens. That is, as the hoistways W1 and W2, it is sufficient to prepare the minimum necessary space for the carriage 20 and the counterweight 31 to ascend and descend, respectively. Since the counterweight 31 at this time is long in the long side direction of the carriage 20, the height of the counterweight 31 can be small. Therefore, it is not necessary to provide a special pit below the hoistway W2.

In the above description, the number of floors of the parking building B is arbitrary, and the number and arrangement of the parking spaces S, S ... Per floor are also arbitrary. For example, the parking spaces S, S ... May be arranged only on one side of the passage B4, or the long side direction may be opposed to the passage B4. Also, the number of elevator devices may be only one, or three or more may be incorporated. Further, in FIG. 4, if the pallet P and the vehicle are transferred from one of the two elevator devices to the other through the truck T on the ground floor GL, only one entrance B3 is required.

A turn device may be provided in the pit W1a on the ground floor GL. At this time, the turn device pushes up the vehicle on the carriage 20 together with the pallet P at the center position of the carriage 20 that stops at the home position and turns 180 degrees in the horizontal direction.
The vehicle can always move in and out in the forward direction.

Further, the parking structure B may be of a ground type or an underground type, or a semi-underground type in which a part is on the ground and a part is underground. Further, the present invention is an elevator device,
It can be applied as it is to a multi-level parking device of a type that is composed of parking spaces S, S, ...
