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 cable 40, a hoisting device 50, and a cage support device 70.
The pallet 10 is a quadrilateral structure on which a vehicle is placed. The pallet 10 is convenient for handling vehicles of various types and sizes. 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 30 incorporates a transfer mechanism that moves the pallet 10 on which the vehicle is mounted between the storage shelf 21 and the lift cage 30.
The cable 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 up or lower the cable 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.

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 cable 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 cable 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 cable 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 device using the lifting device having the above structure, when the vehicle is mounted on the lift cage, the hoisting device adds the total weight of the weight of the lift cage, the weight of the pallet, and the weight of the vehicle to the cable. Wind up and down with 40.
When the vehicle is not placed on the lift cage, the hoisting device winds up and lowers only the weight of the lift cage with the cable 40.
The cable 40 wound around the drive wheel has one end connected to the lift cage 30 and the other end connected to the counterweight.
When the weight of the counterweight is appropriately selected, the power consumed by the hoisting device can be minimized.
For example, when the weight of the lift cage is 2500 kg, the weight of the pallet is 500 kg, and the weight of the vehicle is 2500 kg, the weight of the counterweight is selected to be 3500 kg. In this way, when the vehicle is placed on the lift cage, a weight of 5500 kg acts on one end of the cable and a weight of 3500 kg acts on the other end of the cable. When the vehicle is not placed in the lift cage, a weight of 2500 kg acts on one end of the cable, and a weight of 3500 kg acts on the other end of the cable. The lift cage is accelerated or decelerated and moved up and down into the hoistway while supporting a torque that is the difference between the torque caused by the force acting on one side of the cable and the torque acting on the other side.

The type of the hoisting device may be a type in which a cable is wound around a sheave that is rotationally driven, and torque acting on the sheave is transmitted to the cable by a frictional force between the sheave of the cable. This type of hoisting device has a characteristic that torque transmission becomes unstable when the difference between the weight acting on one end of the cable wound around the sheave and the weight acting on the other end of the cable becomes large. Have.
In general, the weight of the lift cage and pallet can be reduced to reduce the weight of the parking device and save driving power. However, if the weight of the lift cage and the weight of the pallet are reduced, the weight of the counterweight is appropriate. Even when the vehicle is selected, when the vehicle is mounted or when the vehicle is not mounted, the above-described difference in weight cannot be kept within a certain value, and it is necessary to devise in order to stabilize torque transmission.

A lift cage 30 on which a vehicle (object) can be placed on a hoistway H next to a plurality of storage shelves 21 arranged in the vertical direction is a winding composed of a drive wheel 51, a drive mechanism 57, and a counterweight 58. The upper device 50 is hung at one end of the cable that is wound up and down, the counter weight 58 is hung at the other end, and another auxiliary driving wheel 61, auxiliary driving mechanism 63, auxiliary counterweight 65, auxiliary cable, Since the clutch mechanism of the auxiliary hoisting mechanism 60 constituted by the clutch mechanism 66 can connect or disconnect the rotating shaft of the driving wheel 51 and the rotating shaft of the auxiliary driving wheel 61, the clutch mechanism 66 is connected to the driving wheel 51.

Can be lowered.
Further, the auxiliary driving wheel 61 and the auxiliary idler wheel 62 are arranged apart from each other in the vertical direction, the auxiliary cable 64 is passed over the auxiliary drive wheel 61 and the auxiliary idler wheel 62, and the auxiliary idler wheel 62 is urged downward. Therefore, since tension always acts on the auxiliary cable 64, the auxiliary drive mechanism 63 can raise and lower the auxiliary counterweight 65 stably.
Further, since the electric power obtained by regenerative braking when the lift cage 30 carrying the vehicle and the pallet is lowered is used as the power for raising the auxiliary counterweight 65, the drive mechanism 57 and the auxiliary drive are used. The total power for operating the mechanism 63 can be saved.
Further, since the electric power obtained by regenerative braking when lowering the lift cage 30 on which the pallet is placed is used as power for raising the auxiliary counterweight 65, the drive mechanism 57, the auxiliary drive mechanism 63, Can save the total power to operate.
Further, for example, since it takes about 20 seconds to raise the lift cage in the normal operation cycle of 120 seconds, the auxiliary counterweight only needs to be raised within the remaining 100 seconds. The output required for the power supply can be small and can be operated with small power.
