Description

The present invention relates to a work floor construction device for an elevator parking device.

The elevator type parking device is a mechanical parking device that raises and lowers a vehicle along a hoistway and stores the vehicle in a storage shelf adjacent to the hoistway. Elevator-type parking devices include devices in which the longitudinal direction of the pallet stored in the storage shelf and the entry / exit direction of the vehicle are different. Such an elevator type parking device is disclosed in, for example, Patent Document 1.

FIG. 1 is an explanatory diagram of a conventional elevator-type parking device in which the longitudinal direction of the pallet 3 stored in the storage shelf 6 (hereinafter, the storage direction X) and the entry / exit direction Y of the vehicle 1 are different. In this example, the storage direction X and the warehousing / delivery direction Y are different by 90 degrees.

In FIG. 1, (A) is an overall configuration diagram, and (B) is a plan view of the warehousing / delivery floor 5 immediately before the cage 9 arrives at the warehousing / delivery floor 5. Further, (C) is a plan view of the warehousing / delivery floor 5 at the time of warehousing / delivery of the vehicle 1, and (D) is a plan view of the warehousing / delivery floor 5 at the time of warehousing / delivery when there is no elevating platform 7. There is.

In FIG. 1, the cage 9 has a pallet 3 mounted on the cage 9 and moves up and down the hoistway 4 between the storage shelf 6 and the warehousing / delivery floor 5. A plurality of storage shelves 6 are provided along the hoistway 4. The pallet 3 traversing from the storage shelf 6 onto the cage descends the hoistway 4 toward the warehousing / delivery floor 5.

An elevating swivel device 2 is provided in the center of the cage 9. The elevating and turning device 2 also serves as a traversing device for traversing the pallet 3 between the storage shelf 6 and the cage 9. At the time of warehousing and unloading, as shown in FIG. 1C, the pallet 3 is horizontally swiveled by the elevating swivel device 2 by 90 degrees, and the front-rear direction of the vehicle 1 is directed from the storage direction X to the warehousing / delivery direction Y.

The warehousing / delivery floor 5 is provided with openings 8 extending in the storage direction X and the warehousing / delivery direction Y described above in a substantially cross shape. Hereinafter, the cross-shaped opening 8 is referred to as a “cross opening 8”.

Japanese Unexamined Patent Publication No. 2001-271506

FIG. 2 is an explanatory view of a conventional work floor.
FIG. 2A is a plan view of the warehousing / delivery floor 5 having the cross opening 8. As shown in this figure, there is a large cross opening 8 in the center of the warehousing / delivery floor before the cage is installed.
The width Wx and the length Ly of one of the rectangles of the cross opening 8 correspond to the size of the pallet 3, for example, the width Wx is about 1950 mm and the length Ly is about 5200 mm. The width Wy and the length Lx of the other rectangle correspond to the size of the cage 9, for example, the width Wy is about 2000 mm and the length Lx is about 6000 mm.

In order to assemble the elevator type parking device at the installation site, it is necessary for a worker to enter the warehousing / delivery floor 5 and assemble the upper components (parking shelf 6, cage lifting device, etc.). Therefore, in order to prevent the worker from falling into the cross opening 8, a work floor covering the upper part of the cross opening 8 is required.

Conventionally, for example, PecoBeam (registered trademark) has been used as a work floor for covering the cross opening 8.
FIG. 3 is a schematic view showing the configuration of the Pecobeam PL. In this figure, (A) shows the outer beam AL, (B) shows the inner beam BL, and (C) shows the three-connected peco beam PL.
In the peco beam PL, the outer beam AL and the inner beam BL are of a pull-out type, and the inner and outer beams are combined to obtain an arbitrary span.

FIG. 2B is an example in which PecoBeam PL is used on the work floor covering the upper part of the cross opening 8. When constructing a work floor using PecoBeam PL, the maximum span of the cross opening 8 is large (for example, length Ly = about 5200 mm). Therefore, as shown in FIG. 3C, three Pecobeam PLs are connected, the weight of one beam exceeds about 60 kg, and it takes time and labor to construct the work floor.

FIG. 2C shows a conventional work floor after the cage 9 is installed in the cross opening 8. When the cage 9 is installed, a rectangular opening remains only in the center of the upper part of the cage 9, and elevating platforms 7 are present on both sides thereof.
Therefore, the work floor after the cage 9 is installed is different from FIG. 2B, in that the rectangular opening in the center of the cage is closed with, for example, a control panel CP, and the two rectangular openings on the outside of the cage 9 are, for example, a short span pecobeam PL. The scaffolding board was constructed using. The "control panel" is an abbreviation for a concrete panel, and means a plywood having basic dimensions of 900 mm × 1800 mm × 12 mm.
However, in the conventional work floor, when the cage 9 is installed and after the cage is installed, the three-joint Pecobeam PL shown in FIG. 2B is removed, and the work floor is constructed only with the control panel and the scaffolding floor. It was a stable work floor.

The present invention has been devised to solve the above-mentioned problems. That is, the first object of the present invention is to provide a work floor construction device for an elevator type parking device that does not need to be changed before and after the installation of the platform after the cage is installed. A second object of the present invention is to provide a work floor construction device for an elevator type parking device that can cover the upper part of the cross opening with a shorter span than before.

According to the present invention, it is a work floor construction device of an elevator type parking device.
The elevator type parking device has a floor opening provided on the entry / exit floor.
The floor opening has a first rectangular opening that is rectangular in a plan view having a long storage direction.
The work floor construction device is
A cage frame having a rectangular frame frame that extends horizontally along the inner edge of the first rectangular opening inside the first rectangular opening and whose upper end is located below the warehousing / delivery floor.
Provided is a work floor construction device for an elevator parking device, comprising an internal work floor that closes a rectangular opening located inside the cage frame.

According to the configuration of the present invention, the work floor construction device has a cage frame and an internal work floor.
The cage frame has a rectangular frame frame that extends horizontally along the inner edge of the first rectangular opening inside the first rectangular opening, and the upper end is located below the warehousing / delivery floor.

Since the rectangular opening located inside the cage frame has a shorter span than before (for example, the width of the first rectangular opening), the internal work floor can be made of a lightweight member having low rigidity.

Moreover, since the cage frame and the internal work floor can be constructed as a work floor after the cage is installed, there is no need to change the cage frame and the internal work floor before and after the installation of the platform after the cage is installed.
