Description

[Detailed Description of the Invention] 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.

In general, in parking lots in areas with heavy snowfall, snow adhering to cars melts and accumulates on the floor of the cage. is bordered and fitted with a rubber stopper 3, and when the cage reaches the lowest part of the multi-story parking facility, the rubber stopper 3 is manually removed to drain the melted snow water. However, due to the rise in labor costs in recent years, the aim of streamlining operational management without having to assign full-time operators to the parking lot itself has been changed.
Recently, a cage drainage device as shown in FIG. 2 has been proposed.

That is, the drain plug 4 is removably fitted into the drain hole provided in the floor 1 of each cage, and when each cage is located at the lowest part of the multi-story parking facility, the drain plug 4 collides with the lower surface of the drain plug 4 and the drain plug 4 is removed. There is a drainage device in which a cam 6 is provided on the pit floor 5 so as to lift the cage 4 and drain the water accumulated on the cage floor surface from the drain hole.

However, in a device like this, in which a cam is installed on the pit floor and water is drained by collision between the cam and the drain plug, an impact noise is generated between the cam and the drain plug each time each cage passes the bottom. This not only creates a new source of noise, but also results in water being scattered on the pit floor due to incomplete drainage during cage circulation. In addition, not only water but also sand, dirt, etc. accumulate on the cage floor, so it is necessary to clean the cage floor from time to time, and there has been a demand for a cage floor structure that is easy to clean and has few irregularities.

The present invention has been developed in view of the above points, and an object of the present invention is to provide an automatic drainage device that generates less noise, can drain water efficiently, and is easy to clean.

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

FIG. 3 is a partial front view of a cage equipped with an automatic drainage device according to the present invention, FIG. 4 is a plan view of FIG. 3, and FIG. 5 is a sectional view taken along the - line in FIG.
In the figure, reference numeral 10 denotes the floor of a cage provided with a car wheel entry area 10a formed in a concave shape with an appropriate depth, and a water drain hole 10b is provided in the wheel entry area 10a. 11 is a bracket 11a and a shaft 11b (the shaft 11b is fixed to the floor 10, and one end of the bracket 11a is fixed to the shaft 11b) on the back side of the floor 10 of the cage so that water, sand, etc. that fall from the drain hole 10b can be stored inside. It is rotatably attached, and the other end is the tank 1
For example, this tank 11 has a tapered structure in which the bottom is deeper toward the center of the cage floor and becomes shallower toward the tip. A rotatable roller 11c is provided on the side surface so as to protrude toward a rod 13, which will be described later. 13 are brackets 13a and 13b on the back side of the floor 10 of the cage.
It is a hollow rod that is slidably supported in the front-rear direction (horizontal direction in FIG. 5) via the brackets 13a and 1.
3b, the intermediate portion of the tank 11 facing the roller 11c has a curved portion 13c concave downward in the direction away from the roller 11c in a vertical plane, for example, as shown in FIG. is in contact with the upper surface of this rod 13 to support the tank 11. 17 has different diameters at both ends, one end of the smaller diameter side is slidably inserted into the tip of the rod 13, and the other end of the larger diameter side is inserted through the bracket 18 to the back side of the floor 10 of the cage. A spring seat 19 is provided approximately at the center of the rod, and a spring 20 is inserted between the spring seat 19 of the rod 17 and the spring seat 15 of the rod 13.

In the device of the present invention having such a configuration,
When the car is driven to, for example, a car loading/unloading position on the lowest floor and stops, the drive device 30 operates and the push lever 31 moves in the direction of arrow A (rearward direction) in FIG. The part is rod 13
is moved in the direction of arrow A against the spring pressure of spring 20. Then, the roller 11c of the tank 11
is guided by contacting the curved portion 13c of the rod 13, the tank 11 rotates counterclockwise due to its own weight around the shaft 11b, tilts as shown by the two-dot chain line in FIG. Drain the water all at once from the tip.

On the other hand, when the cage is circulated from the car loading/unloading position, the drive device 30 is reversed and the push lever 31 is moved by arrow B before the cage starts circulating.
Spring 2 is used to move the
Due to the spring pressure of 0, the rod 13 also moves back in the direction of arrow B, performing the opposite operation to that described above, that is, the tank 11
By pushing up the roller 11c guided by the rod 13, the tank 11 is rotated clockwise about the shaft 11b and returned to its original state as shown by the solid line in FIG.

As described above, according to the present invention, water can be drained without sprinkling water by tilting the tank when each cage is stopped at the car loading/unloading position, so that water can be drained without sprinkling water. No impact noise is generated. Also, since it is only necessary to provide a drainage hole on the cage floor,
Cleaning can be done extremely easily.
