Description

  The present invention relates to a parking device that parks a vehicle and a lifting device that lifts and lowers an object in a hoistway. In particular, the present invention relates to a parking device and a lifting device that are characterized by a structure for hanging a vehicle or an object.

A mechanical parking device is used to park the vehicle.
For example, the vehicles are stored in storage shelves arranged in the vertical direction.
An example of this type of parking device includes a plurality of pallets 10, a plurality of storage shelves 21, a lift cage 30, a wire 40, a hoisting device 50, and a cage support device 70.
The pallet 10 is a quadrilateral structure on which a vehicle is placed. Since the pallet 10 is convenient for handling vehicles of various types and sizes, a general parking apparatus uses the pallet 10 to handle the vehicle. Some parking devices handle vehicles without using a pallet.
A storage shelf is a shelf which can store a vehicle. A plurality of storage shelves 21 are arranged in the vertical direction. Usually, a plurality of parking shelves arranged vertically are arranged on the left and right sides of the hoistway. An entry / exit space S is provided in the middle of the hoistway H.

The lift cage 30 is a structure on which a vehicle can be placed. The lift cage incorporates a transfer mechanism that moves the pallet on which the vehicle is placed between the storage shelf 21 and the lift cage 30.
The wire 40 is a mechanical element that suspends the lift cage 30 along the storage shelf.
The hoisting device 50 is a device that can wind or unwind the wire 40.
The cage support device 70 is a device that supports the lift cage 30 on the building of the parking device when aligned next to one of the storage shelves.
The cage support device 70 supports the lift cage on the main structure by matching the rail surface level of the rail on the pallet in the lift cage with the rail surface level of the rail on the pallet in the storage shelf.

FIG. 7 is a perspective view of a conventional lifting device.
The hoisting device 50 includes a driving sheave 51, an idle sheave 52, a hoisting sheave 53, a turning sheave 55, a driving mechanism 57, and a counterweight 58.
Four hoisting sheaves 53 are arranged above the hoistway at positions facing the four corners of the lift cage 30.
Four sets of wires are connected to the lift cage 30 at one end, which is lowered downward from the hoisting sheave 53, and is horizontally stretched between the hoisting sheave 63 and the driving sheave 51. It is wound over a horizontal arc by 180 degrees or more, is wound around the idle sheave 52, and an end portion lowered downward from the idle sheave 52 is connected to the counterweight 58.
With such a configuration, the counterweight 58 moves up and down along hoistways arranged in the vertical direction.

The operation when the vehicle is stored in the parking device will be described.
The vehicle self-propels into the lift cage 30 placed in the entry / exit space S.
The hoisting device 50 winds up the wire 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
The transfer device transfers the pallet on which the vehicle is placed to the storage shelf, and the warehousing is completed.

Next, the operation when the vehicle is taken out from the parking device will be described.
The hoisting device 50 winds up the wire 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
The transfer device transfers the pallet on which the vehicle is mounted from the storage shelf to the lift cage.
A cage support device disengages the lift cage.
The hoisting device 50 lowers the wire 40 and lowers the lift cage 30 to the loading / unloading space.
The vehicle runs out of the entry / exit space S.

In the parking apparatus using the elevating apparatus having the above structure, the elevating apparatus moves up and down along a storage shelf in which counterweights are arranged vertically.
As a result, problems may arise when planning many variations of parking devices using the lifting device having the above structure.
For example, there may be a case where a plurality of storage shelves arranged vertically are arranged in the front-rear direction and a plurality of lifting devices are arranged in the front-rear direction. In this case, since the counterweights move up and down between the storage shelves arranged in the front-rear direction, it is difficult to reciprocate the pallet between the storage shelves aligned in the front-rear direction.

  In addition, since the lift cage moves up and down in the hoistway and the counterweight 58 moves up and down along the storage shelf, it is necessary to take safety measures at two locations.

If the parking device and the lifting device of the above-described embodiment are used, the following effects are exhibited.
The parking device can store a vehicle in which a plurality of storage shelves of the main structure are arranged in the vertical direction, a lift cage (corresponding to an object) can be placed on the vehicle, and the lift cage is placed on the storage shelf. A first wire and a second wire that can be hung in a hoistway extending up and down along the hoistway can be hung in a hoistway extending up and down along the storage shelf. The idle sheave and the counterweight sheave are provided above the hoistway, and the idle sheave is provided rotatably below the drive sheave with the wire grooves facing each other.
In the parking device or the lifting device, the first wire 41 is connected to the lift cage 30 at one end lowered from the drive sheave 51 and wound around the drive sheave 51 in contact with the upper wire groove. The idle sheave 52 is wound in contact with the wire groove on the side near the drive sheave 51, is spanned between the idle sheave 52 and the counterweight sheave 54, is wound around the counterweight sheave 54, and the counterweight The other end lowered from the sheave 54 is connected to the counterweight 58.
The second wire 42 is connected to the lift cage 30 at one end that is lowered downward from the hoisting sheave 53, wound around the hoisting sheave 53, and hung between the hoisting sheave 53 and the idle sheave 52. Passed and wound on the idle sheave 52 in contact with the upper wire groove near the drive sheave 51, wound on the drive sheave 51 in contact with the side wire groove, and driven sheave 51 and counterweight sheave 54 The other end of the counterweight sheave 54 that is lowered downward is connected to the counterweight 58.
Thus, when the drive mechanism 57 rotates the drive sheave 51 to one side, the lift cage 30 is raised and the counterweight 59 is lowered, and when the drive mechanism 57 rotates the drive sheave 51 to the other side, the lift cage 30 is lowered. As a result, the counter weight 58 rises.
Further, since the drive sheave 51 is provided at the front part above the hoistway H and the hoisting sheave 53 and the counterweight sheave 54 are provided at the rear part above the hoistway H, the counterweight 58 is lifted. By raising and lowering the rear of the cage 30, the space of the hoistway H can be used effectively, and variations of the parking device can be increased.
Further, since the idle sheave 52 is rotatably provided with the wire grooves facing each other at an angle of approximately 45 degrees below the drive sheave 51, the winding angle of the first wire 41 with respect to the drive sheave 52 and the second The winding angle of the wire 42 with respect to the drive sheave 51 can be made substantially equal and the force transmitted to the first wire 41 or the second wire 42 by the drive sheave 51 is stabilized.
The first wire 41 is wound around the drive sheave 51 in contact with at least the upper half arc portion of the wire groove, and the second wire 42 is wound around the drive sheave 51 in contact with at least the horizontal half arc portion of the wire groove. Since the winding angle of the first wire 41 with respect to the driving sheave 51 and the winding angle of the second wire 42 with respect to the driving sheave 51 exceed 180 degrees, the driving sheave 51 is connected to the first wire 41 or the second wire 41. The force transmitted to the wire 42 is stabilized.
