Description

[Detailed description of the invention] [Field of industrial application] This invention is a multi-story parking lot installed in a snow-covered area, which is designed to drain melted snow water that accumulates on the pallets on which cars are placed. This relates to drainage equipment.

[Conventional technology]

An example of a multi-story parking lot will be explained with reference to FIG. 5. 1, 1 is a lower sprocket, and an endless chain 2, 2 is stretched between it and an upper sprocket (not shown) so as to circulate. A large number of cages 3 are suspended from 2, 2. A car (not shown) is placed on a pallet 4 supported by the cage 3, and as the chain 2 circulates, it moves up and down with the cage 3, making it possible to store, store, and take out the car. There is. At the bottom of such a multi-story parking lot, there is a turntable 5 that rotates horizontally, and a jack 6 that raises the pallet 4 at the lowest position together with the turntable 5.
It can be lifted up and rotated 180 degrees to change the direction of the car.

By the way, in a multi-story parking lot installed in a snowy area, snow that has accumulated on cars becomes melting water, so it is necessary to have a way to drain this water. Therefore, as shown in FIG. 6, water tanks 7, 7 formed lower than the cage 3 are provided, and the base ends of the drain hoses 8, 8 are connected to
Normally, the tip of 8 is turned upward as shown in FIG. 6, so that melted snow water collects in water tanks 7, 7. When the pallet 4 is circulated to the lowest position, it is lifted up by the jack 6 (see Fig. 5) and placed in the water tank via the cage connecting pipe 9 (see Figs. 6 and 7) connecting the front and back of the cage 3. 7
After raising the position of the drain hose 8, the tip of the drain hose 8 is directed downward as shown in FIG. 7, and the melted snow water accumulated in the water tank 7 is drained.

[Problem that the invention attempts to solve]

However, the conventional drainage device shown in FIGS. 6 and 7 described above has the following drawbacks.

Drainage cannot be done unless the cages 3 corresponding to the number of parked cars are circulated one by one to the lowest level, which takes time.

Since there is a cage joint pipe 9 on the side of the drain hose 8, the pallet 4 cannot be drained unless the pallet 4 is lifted up with the jack 6.

The area where the water is drained is near the place where motor vehicle drivers get on and off, making it dangerous for drivers to walk due to freezing of the wastewater.

Since the drain hose 8 is installed at the position where the driver gets on and off the vehicle, it becomes a nuisance and is also unfavorable from a design point of view.

There are two water tanks 7 on the left and right sides of the pallet 4,
Since the drainage hose 8 is also attached to the left and right sides of the pallet 4, one pallet 4
This requires two drainage operations, which is time-consuming.

The present invention improves the drawbacks of such conventional devices,
To provide a drainage device for pallets in a multi-story parking lot that can automatically drain melted snow water without much effort.

[Means for solving problems]

The present invention consists of a water tank formed low in the roadway of a pallet on which a car is placed, a drainage hose whose base end is connected to the water tank, and a drainage hose that is pivotally attached to the pallet and rotates to drain the tip of the drainage hose. A link mechanism that displaces the pallet to a position higher and lower than the tank, a holding spring that rotates the link mechanism so that the tip of the drain hose is held at a position higher than the water tank, and a holding spring that raises the pallet and rotates it horizontally. A turntable is attached to the turntable and is urged upward by a spring, and when the turntable raises the pallet, the link mechanism is rotated against the holding spring, displacing the tip of the drain hose to a position lower than the water tank. This is a drainage device for pallets in a multi-story parking lot, which is equipped with a pusher for draining water, and a drainage tank attached to a turntable and containing water flowing out from a drainage hose.

[Effect]

When the car enters or exits the garage, the turntable's pusher rotates the link mechanism and displaces the tip of the drain hose to a position lower than the water tank, so the melted snow in the water tank is automatically drained into the turntable's drainage tank. It will be drained.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, 3 is a cage, 4 is a pallet on which a car is placed, and 9 is a cage connecting pipe.
A part of the roadway 10 of pallet 4 is lowered,
A water tank 11 is formed. The roadway 10 slopes downward toward the water tank 11, and the roadway 10 slopes downward toward the water tank 11.
The water that has fallen to zero flows into a water tank 11. Note that a lid (not shown) is placed on top of the water tank 11 to form a flat surface with respect to the roadway 10.
It is now possible to avoid hindrance to the entry and exit of automobiles. A base end 13 of the drain hose 12 is provided on the inner side surface of the water tank 11.
is connected.

As shown in FIG. 2, the base end 1 of the drain hose 12
The bent portions of the cross-shaped links 14 and 15 are connected to the pins 16 and 15 on the side of the water tank 11 on the side where the
17, each upper end of the square link 14 is rotatably connected by a straight link 18 and pins 19, 20, and the square links 14, 1
5. A link mechanism is formed by the straight links 18. At the lower end 21 of the cross-shaped link 15,
A ring 22 connects the distal end 23 of the drain hose 12.

A retaining spring 24 is mounted under tension between the pallet 4 and the portion of the pin 19 that rotatably connects the upper end of the square link 14 to the straight link 18. This retaining spring 2
4, the straight link 18 is pulled to the left in FIG. , drainage hose 12
The tip 23 of is pulled upward via the ring 22 and held at a higher position than the water tank 11.

When the pallet 4 circulates vertically and reaches the lowest position, the turntable 5, which is located directly below the pallet 4, has a drainage tank 25 and a pusher 26.
is installed. The drain tank 25 is located below the drain hose 12, and the pusher 26 is configured to be able to slide vertically relative to the turntable 5, and is biased upward by a spring 27. The force of this spring 27 is set to be stronger than that of the holding spring 24 described above. 28 is a retaining pin attached to the pusher 26. Palette 4 is at the bottom,
When the turntable 5 is not raised,
The lower end 29 of the shaped link 14 and the upper end of the pusher 26 are arranged vertically with a gap 30 in between.

In the above-mentioned apparatus, in order to circulate the pallet 4 to the lowest position and change the direction of the cars loaded on the pallet 4, the turntable 5 shown by the chain line in FIG. When it rises to the position shown, turntable 5
The upward stroke 31 of the gap 30 shown in FIG.
Since the size is larger than that of the pusher 26, the upper end of the pusher 26 is connected to the cross-shaped link 14 as shown in FIG.
It comes into contact with the lower end 29 of and pushes it upward. Since the spring 27 is set to have a stronger force than the retaining spring 24, the spring 27 does not bend significantly, the retaining spring 24 expands, and the square link 14 rotates clockwise about the pin 16. . As a result, the straight link 18 is pushed to the right, the square link 15 also rotates clockwise about the pin 17, and the lower end 21 of the square link 15 is displaced downward. Therefore, the tip 23 of the drain hose 12 is moved to a position lower than the water tank 11 via the ring 22, and the melted snow water accumulated in the water tank 11 is drained into the drain tank 25.

When the turntable 5 descends, it returns to the state shown in FIG. 2 due to the force of the holding spring 24, and the tip 23 of the drain hose 12 is held at a higher position than the water tank 11, and melted snow water is no longer drained from the water tank 11. .

If the snow melt that has accumulated in the drain hose 12 freezes in the state shown in FIG. . If the turntable 5 rises in such a state, the fourth
As shown in the figure, the spring 27 is bent and the pusher 26 is lowered to prevent undue force from being applied to the square links 14, 15 and the straight link 18, thereby preventing damage.

[Effect of idea]

Since the turntable always rises when a car enters or leaves the garage, the present invention automatically drains snow melt water when the car enters or leaves the garage.

Furthermore, the present invention does not require any special power or interlock for the drainage hose, so the device is simple and can be installed in a location that is not visible from the outside to improve the appearance.

Furthermore, even if the drain hose freezes, no excessive force is applied to it, which prevents it from being damaged.
