Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an entry / exit structure for a three-dimensional parking lot, and more particularly to an improvement in the entry / exit structure having a turning mechanism for changing the direction of a vehicle.

[0002]

[Prior Art]

 In a three-dimensional parking lot, there are usually provided a loading / unloading floor for loading / unloading vehicles and a parking floor for parking at least one layer of vehicles on at least one of the floors above and below. On the entry / exit floor, a turning mechanism is provided to avoid the hassle of moving the vehicle in and out by moving backwards. With the help of this, the vehicle can enter and leave while driving forward.

An example of such a turning mechanism is disclosed in Japanese Patent Publication No. 63-5539. An outline of this turning mechanism is shown in FIGS. 4 and 5. This three-dimensional parking lot is underground, and is composed of a loading / unloading floor A that is flush with the road surface and two underground parking floors B1 and B2. At the time of storage, the vehicle enters from the storage floor A and stops on the pallet unit 1. The pallet unit 1 is carried downward by the lift mechanism 2, and the vehicle is accommodated on the stop parking floor by stopping at either the parking floor B1 or B2. When leaving the vehicle, the vehicle goes from one of the parking floors to the pallet unit 1, and when the pallet unit 1 is carried to the upper loading / unloading floor A by the lift mechanism 2, the vehicle goes out of the loading / unloading floor A. At the time of loading and unloading, the pallet unit 1 turns with the turntable 3 with the vehicle mounted. Various mechanisms have been proposed for the movement of the vehicle between each parking floor and the pallet unit 1, and a description thereof will be omitted here.

Such a turning mechanism will be described in more detail with reference to FIG. The turntable 3 is disk-shaped and is provided flush with the vehicle running surface of the entry / exit floor A, and has a rectangular opening 31 corresponding to the pallet unit 1 in the center thereof, and a turning drive mechanism in the peripheral portion. 32 is engaged. The pallet unit 1 is composed of a rectangular pallet 11 received in the opening 31 of the turntable 3 and a pallet frame 12 on which the pallet frame 12 is mounted, and a pinion 13 integrated with the pallet frame 12 cooperates with a pallet rotation drive mechanism 14. There is.

When the vehicle is loaded, the pallet unit 1 turns 90 degrees from the state shown in the figure together with the turntable 3 at the time of loading and then descends by the lift mechanism 2. At the time of leaving the warehouse, the pallet unit 1 is loaded with the vehicle, then lifted by the lift mechanism 2 and turned 90 degrees together with the turntable 3 at the position shown in the figure.

[0006]

[Problems to be solved by the device]

 As described above, in the conventional loading / unloading structure, the turning mechanism has the outer turntable 3 and the pallet unit 1 received inside thereof located flush with each other. You need to turn. For this reason, the structure around the swivel drive mechanism becomes complicated, and not only the equipment cost is high, but also the maintenance and management costs are high, and the generation of noise doubles. In particular, since a multi-storey car park is usually located in a densely populated area, the noise generated by frequent entry and exit can be a serious environmental social problem.

An object of the present invention is to solve the problems of equipment cost, maintenance cost and noise generation peculiar to a three-dimensional parking lot having a turning mechanism for loading and unloading.

[0008]

[Means for Solving the Problems]

 For this reason, in this invention, a pallet unit that is driven by a lift mechanism to move up and down for loading and unloading of a vehicle is provided, and the pallet unit is rotated at a position slightly above the vehicle running floor on the loading and unloading floor. The point is that it is configured to do.

[0009]

[Action]

 The pallet unit, with the vehicle mounted, turns at a position slightly above it without interfering with the surrounding vehicle running floor on the entry / exit floor.

[0010]

【Example】

 1 to 3 show an example of a loading / unloading structure of the present invention. The same parts as those in FIGS. 4 and 5 are designated by the same reference numerals, and the description thereof will be omitted. In the present invention, a turntable is not necessary, and an opening 15 corresponding to the pallet unit 1 is provided on the vehicle running floor of the entry / exit floor A. The pallet unit 1 is composed of a rectangular pallet 11 received in the opening 15 and a pallet frame 12 having the pallet frame 12 mounted therein, and a pinion 13 integral with the pallet frame 12 is engaged with the pallet rotation drive mechanism 14. The pallet unit 1 is configured to have a turning angle of 180 degrees by the pallet turning drive mechanism 14.

On the other hand, the lift mechanism 2 has a lift frame 22 on which the pallet unit 1, the pinion 13 and the pallet turning drive mechanism 14 are mounted, and a guide rail 21. The guide rail 21 extends from the parking floors B1 and B2 to near the vehicle running floor of the entry / exit floor A. As shown in FIG. 2, the lift mechanism 2 can be driven to a position where the pallet unit 1 projects slightly above the vehicle running floor surface (strictly speaking, the pallet frame 12 is slightly away from the vehicle running floor surface). In this protruding state, the pallet unit 1 can be rotated 180 degrees. This is because there is no turntable so that when the pallet unit 1 turns, there is no possibility that part of it will come into contact with the vehicle running floor.

With this configuration, when loading and unloading on the loading / unloading floor A, the pallet unit 1 on which the vehicle is placed is driven by the lift mechanism 2 so as to project slightly above the vehicle running floor surface, It is driven to turn. That is, at the time of warehousing, the lift mechanism 2 is driven so as to move slightly upward when the vehicle rides on the pallet 11 which is flush with the traveling floor of the vehicle, and the pallet unit 1 is further swung 180 degrees. The lift mechanism 2 is driven so as to descend to the parking floor B1 or B2.

On the other hand, at the time of unloading, the lift mechanism 2 is lifted from the parking floor B1 or B2 with the vehicle placed on the pallet 11 and stopped at a position where the pallet unit 1 projects slightly above the vehicle running floor surface. After being stopped, the pallet unit 1 is rotated 180 degrees after being stopped. Subsequently, the lift mechanism 2 is driven so that the pallet 11 descends to a position where the pallet 11 is flush with the vehicle running floor surface. The above control operation is performed by the operator operating the control device at the entry / exit floor A while monitoring. FIG. 3 shows a 90-degree turning state in the middle of a 180-degree turning.

[0014]

[Effect of the device]

 Since a turntable is not used in the present invention, the structure becomes simpler, the installation cost and maintenance cost are reduced accordingly, and the noise generation at the time of loading and unloading is significantly reduced.
