The elevator parking facility has a parking space in which a pallet can be transferred to or lifted from a lift on a hoistway, or a pallet moved from a hoistway can be placed in a parking compartment. Pallet position detection device is provided to detect each position.

1 is a schematic longitudinal sectional view of a conventional elevator parking facility, and FIG. 2 is a plan view of a driving motor installation area of the elevator parking facility of FIG. 1. As shown in these drawings, the elevator parking facility includes a hoistway (W) formed along the up and down direction, a plurality of parking spaces (P) disposed on both sides of the hoistway (W), and the hoistway (W). It has a lift (not shown) arrange | positioned so as to be able to move up and down inside, and the some pallet 11 arrange | positioned in the parking space P so as to be transverse between the parking space P and the hoistway W. In the hoistway (W), a plurality of guide rails (13) are erected in parallel to each other so as to guide the hoisting and lifting of the lift. And the hoistway guide rail 15 and the parking room guide rail 41 is provided so as to support each.

The hoistway guide rails 15 are provided with a plurality of transverse rollers 17 protruding toward the center area of the hoistway W and spaced apart from each other along the longitudinal direction, and on the other end of the rotating shaft of each transverse roller 17. The wheel 19 is integrally rotatable. The sprocket wheels 19 disposed on the hoistway guide rails 15 are connected by a floor-drive motor 21 so as to be integrally rotatable with each other.

One of the hoistway guide rails 15 corresponding to each floor along the up and down direction is provided with a drive motor 23 so as to rotate each of the row rollers 17 simultaneously, and one side of the drive motor 23. It is provided with a pair of electric sprocket wheel 25 to receive the rotational force from the drive motor (23). Corresponding to the upper side and the lower side of the electric sprocket wheel 25, each hoistway guide rail 15 is provided with a floor drive sprocket wheel 27 coaxially provided with each other.

One of the floor sprocket wheels 27 is arranged along the vertical direction of the hoistway W and coupled to the interlayer drive chain 29 engaged with the electric sprocket wheel 25 so that the floor drive sprocket wheels 27 of each floor are integrated. It will rotate by. The other one of the floor drive sprocket wheels 27 is coupled to the floor drive chain 29 so as to rotate the sprocket wheel 19 installed on the same hoistway guide rail 15.
