Description

[Detailed description of the invention] [Industrial field of application] The present invention is a cage in which the floor of a cage (the entire cage floor, a part thereof, a pallet placed on the cage floor, etc.) is configured to be freely rotatable. The present invention relates to an improvement in a drainage device that automatically drains water accumulated on a car storage cage of a mechanical parking device.

[Prior art]

Generally, as shown in FIG. 2, the cage of a mechanical parking device with a built-in turning function has an engaging plate 11a of cage frames 11 and 11' connected by a connecting member 12 between the upper parts and a connecting member 13 between the lower parts. , 11a', the cage floor 14 shown in FIG. 3 is removably attached to the cage floor 14 shown in FIGS.
1 (composed of a lifting device 30, a traversing device 40, and a turning device 50)
It has a structure in which it is lifted and rotated by a rotating frame 52.

Therefore, in order for the rotating frame 52 to be able to rotate without any hindrance, the rotating frame 52 must be raised above the connecting member 13 by the lifting device 30, as shown in FIG. 6, and then rotated. . This means that the floor 14 of the cage must be raised that much before it can be swiveled.

By the way, with regard to mechanical parking devices installed in areas with a lot of snow, snow adhering to cars melts and accumulates on the floor 14 of the cage.
A tank is provided in the tank, and melted snow water is stored in the tank, and when a predetermined amount has accumulated, the tank is rotated to drain the water.

[Problem that the invention attempts to solve]

However, as shown by the two-dot chain line in FIG. 6, this tank has a structure that naturally protrudes downward from the back of the cage floor, so when the tank 15 rotates, the connecting member 15
3, the swing frame 52 must be raised further before turning, and the upper connecting member 12 when the car on the cage floor 14 rises.
The clearance between the vehicle and the parking lot will become smaller, and the effective height of the parked vehicle will be reduced by that amount.

Therefore, as shown in FIGS. 7a, b, and c, tanks 15 are formed on the left and right lower sides of the front and rear parts of the cage floor.

A tank 15 formed on the cage floor is positioned inside the rotating frame 52.

A tank 15 formed on the cage floor is fitted into a recess of the revolving frame.

Efforts have been made to keep the vertical dimension of the swivel frame 52 as small as possible, but in the case of a normal mechanical parking device with a drainage device that does not have a swivel function, and in the case of a mechanical parking device with a drainage device that has a built-in swivel function. The structure of the cage floor changes significantly depending on whether it is a mechanical parking device with a turning function or a mechanical parking device without a turning function and no drainage device, which inevitably increases costs. Another disadvantage was that the shape of the tank was complicated, making it difficult to manufacture the cage floor.

The present invention has been made in view of the above points, and an object of the present invention is to provide an automatic drainage device that has a simple cage floor structure and that does not impair the effective height of parked cars.

[Means for solving problems]

In this invention, the cage frame is removably equipped with a cage floor for mounting on a vehicle tower, etc., which has water drainage holes in the wheel entry recess, and a lifting device equipped with a turning device is installed in the pit, and the lifting device can be raised. The revolving frame of the revolving device lifts the back surface of the wheel entry recess of the cage floor, etc., and the revolving frame rotates the cage floor, etc., in which a valve is provided in the drain hole of the cage floor, etc., and the revolving frame is a hollow member inside. A hole is provided on the surface facing the drain hole, and a hole is also provided on the surface facing the pit, and the valves on the cage floor etc. are opened and closed by a revolving frame.

[Effect]

With the above-described structure, the valves on the cage floor, etc., are automatically opened and closed in accordance with the elevation and descent of the revolving frame, and water accumulated on the cage floor is appropriately drained.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an example of a cage floor 140 according to the present invention, FIG. 8 is a perspective view showing an example of a rotating frame 520 having a hollow interior according to the present invention, and FIG. It is a partial sectional view showing the engagement relationship, in which 140a is a drain hole provided in a tapered shape in the cage floor 140, and 140b is a drain hole provided in the cage floor 140.
Left and right recesses 14 into which the wheels of the car No. 0 are inserted
Water stop material provided at both front and rear ends of 0c, 141 is a rubber plug that fits into the tapered drain hole 140a, and an inverted T-shaped push-up rod 142 extending downward is fixed to the back side of this rubber plug 141. A spring 143 is inserted between the back surface of the cage floor 140 and the push-up rod 142, and normally the rubber plug 141 is fitted into the drain hole 140a by the spring force of the spring 143. On the other hand, 520a is a hole provided in the rotating frame 520 opposite to the drain hole 140a of the cage floor 140, and 521 is a hole provided in the rotating frame 52.
This is a convex portion provided inside facing the hole 520a.

With such a configuration, the rotation frame 520 can be rotated in accordance with the actual application in 1986-10 prior to rotation of the cage floor, etc.
No. 106266 (Utility Model No. 62-14056) or Patent Application No.
As shown in No. 61-310961, for example, when the cage is positioned in the circulation direction by a photoelectric device (not shown) and a light shielding plate (not shown) and raised, the convex portion 521 of the rotating frame 520 first touches the push-up rod 142.
, and if the rotating frame 520 further rises, the push-up bar 142 is pushed up against the spring force of the spring 143 as shown in FIG. etc., flow into the rotating frame 520 through the drain hole 140a and the hole 520a. Then the rotating frame 520
further rises to lift the cage floor 140 and rotates the cage floor 140 using a well-known rotating device, while the drainage operation continues.
When the rotation operation of the cage floor 140 is completed and the rotation frame 520 is lowered, the cage floor 140 is placed on the engagement plates 11a and 11a' of the cage frames 11 and 11', and when the rotation frame 520 is further lowered,
The convex portion 521 gradually moves away from the push-up bar 142, and in response to this movement, the push-up bar 142 is pushed downward by the spring force of the spring 143, and the rubber stopper 141 is inserted into the drain hole 140a as shown in FIG. 9a. Fit them together to complete the drainage operation.

By the way, the question now is how to deal with the melted snow that has accumulated in the rotating frame 520 due to the above-mentioned drainage operation, but as shown in FIG. A valve mechanism exactly the same as the one described above is provided on the lower surface of the rotating frame 520 facing the pit floor 16, so that when the rotating frame 520 finishes its rotating operation and descends, the protrusion 17 provided on the pit floor 16 closes the rubber stopper 1.
8 may be opened to discharge water to a predetermined position on the pit floor 16. Further, a separate valve drive mechanism may be provided in the lifting/lowering movement/swivel device to perform the discharging operation.

[Effect of idea]

As described above, according to the present invention, the floor of the cage can have an extremely simple structure with a simple drainage hole and a valve that opens and closes in response to the elevation of the revolving frame. It is economical because it can be unified into approximately the same shape and structure regardless of the relationship. or,
Since the revolving frame itself is hollow and serves as a tank, there is no need to increase the vertical dimensions of the revolving frame itself in order to attach a drainage device.
