Description

The present invention relates to a movable deck that opens and closes an opening for raising and lowering vehicles formed on an entry/exit floor in, for example, an underground mechanical parking system.

For example, an underground mechanical parking system includes a pallet on which a vehicle is placed, and a cage on which the pallet is placed and moved up and down a hoistway. The cage is equipped with a rotating device that horizontally rotates the pallet, so that when entering the warehouse, the cage moves forward so that the vehicle can be placed on the pallet, and the pallet on which the vehicle is placed can be horizontally rotated so that the cage can move forward and exit the warehouse when leaving the warehouse. It has become.

In such a mechanical parking device, the direction in which a vehicle enters and exits the parking floor (the direction in which the vehicle enters and exits) may differ by 90 degrees from the direction in which the vehicle is stored. In this case, since the pallets are located in two directions that differ by 90 degrees on the loading/unloading floor, a cross-shaped opening with a size in which the two pallets are perpendicular to each other is formed on the loading/unloading floor.

When a vehicle enters or leaves the warehouse on the warehouse entry/exit floor, the pallet is located in the vehicle entry direction, so there are two rectangular openings on both sides of the cross-shaped opening in 90 degrees different directions. can.
Since this rectangular opening is part of the hoistway through which the cage moves up and down, it is a very deep (for example, 10 m or more) vertical hole. Therefore, in order for people to enter and exit the warehouse, this rectangular opening must be fully closed so that people can walk safely over it, and when the egress device is activated, the pallet must be turned horizontally and the cage It needs to be fully opened so that it can be raised and lowered.

Therefore, for example, Patent Documents 1 and 2 disclose devices for opening and closing the rectangular opening.

The "movable deck" of Patent Document 1 is composed of a first, second, and third deck that is folded into three sheets. Drives expansion or folding.

The "movable floor device" of Patent Document 2 includes a pair of first sprockets, a pair of second sprockets, a pair of chains, and both ends of the chains are fixed to each other so as to be parallel to each other along the longitudinal direction. A plurality of floor plates are provided, and a movable floor surface is formed by the plurality of floor plates.

In the case of the "movable deck" of Patent Document 1, the deck drive device is located directly above the hoistway and below the second deck. Therefore, during repairs or maintenance, workers had to go under the floor of the deck and work directly above the hoistway, which is a deep vertical hole, and there was a risk that parts or people could fall into the hoistway.
Furthermore, since the chain of the deck drive device is located directly above the hoistway, there is a risk that lubricating oil applied to the chain may fall onto and contaminate the vehicle while it is being lifted or lowered.

On the other hand, in the case of the "movable floor device" of Patent Document 2, both ends of a large number of elongated floor boards are supported by chains, so there are many gaps between the floor boards, making it difficult for people to walk. In addition, there are many parts, and maintenance is laborious and time-consuming.
Further, since the drive devices of Patent Documents 1 and 2 use a chain (or belt), the operation tends to become unstable due to elongation, etc., and noise is generated.

The present invention was devised to solve the above-mentioned problems. That is, a first object of the present invention is to provide a movable deck for a mechanical parking device that can be repaired or maintained directly above a hoistway in a safe and comfortable position without going under the floor. The second objective is to create a movable deck for a mechanical parking system that has fewer gaps between floorboards, can reliably support objects placed on it, prevents members from elongating, allows stable operation, and suppresses noise generation. It is about providing.
