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.

Generally, in parking lots in areas with heavy snowfall, snow adhering to cars melts and accumulates on the floor of the cage, so conventionally, as shown in Fig. The cage was trimmed and fitted with a rubber stopper 3, and when the cage reached the lowest part of the multi-story parking facility, the rubber stopper 3 was manually removed to drain the melted snow water. However, due to the rise in labor costs in recent years, a cage drainage device as shown in Figure 2 has recently been proposed for the purpose of streamlining operational management without having to place a full-time operator in the parking lot itself. ing.

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.

In addition, as in Japanese Patent Application Laid-Open No. 49-83172, a drain port for the tank is provided on the back of the floor of the cage, and a rod is provided on the side of the cage so as to be slidable in the front and back direction, so that the back and forth linear movement of the rod can be drained. An automatic drainage device has also been proposed that drains the water in the tank by converting it into the rotational movement of a lever that opens and closes the mouth, but this requires a conversion device to convert the linear movement into rotational movement, making the device configuration complicated. It is. Since the drain port is located at the bottom of the cage floor, if the drain port opening/closing lever loosens even a little, water will leak regardless of the amount of water in the tank.

The present invention has been devised in view of the above points, and an object of the present invention is to provide an automatic drainage device with an extremely simple structure that can drain water efficiently and with little risk of generating noise.

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

This tank 11 has a shape that slopes toward a drain port 11c provided on the side in the direction toward the tip of a rod 13, which will be described later, and the bottom becomes deeper as it approaches the drain port. 13 is attached to the back surface of the floor 10 of the cage in the front-rear direction (the fifth
It is a rod that is supported slidably in the left and right direction (in the figure), and a spring seat 15 is provided at a position about a dimension _l1 inside from the tip, and a bracket protruding toward the tank 11 near the bracket 14b. 16
The valve 12 is fixed at a position facing the drain port 11c of the tank 11 via the valve 12. 17 is a bracket 18 with one end facing the tip of the rod 13.
with rods fixed to the floor 10 of the cage via
Similarly, a spring seat 19 is fixed at a position about a distance l ₂ from the tip, and a spring 20 is inserted between the tip of the rod 13 and the tip of the rod 17. Then, the spring pressure of the spring 20 is adjusted by turning the double nut 17a for attaching the rod 17 so that the spring pressure of the spring 20 causes the valve 12 provided on the rod 13 to reliably close the drain port 11c of the tank 11 under normal conditions. . (still,
As for the tip of the rod 13, as shown in FIG.
0 may be slidably attached to the rod 13 in the longitudinal direction, and the auxiliary rod 130 may be provided with a spring 200. ) In the device of the present invention having such a configuration, when the cage is driven to, for example, the lowest floor car loading/unloading position and stops, the drive device 30 operates and the pressing lever 31 is moved in the direction of arrow A (rearward direction) in FIG. The tip of the pressing lever 31 moves the rod 13 in the direction of arrow A against the spring pressure of the spring 20, so that the linear movement of the rod 13 is directly transmitted as the linear movement of the valve 12. As shown in the figure, since the valve 12 is opened, the water accumulated in the tank 11 is discharged all at once from the drain port 11c.

On the other hand, when the cage is circulated from the car loading/unloading position, the drive device 30 reverses and moves the pressing lever 31 in the direction of arrow B (forward) before the cage starts circulating. Due to the spring pressure, the rod 13 also moves back in the direction of arrow B, and the valve 12 closes the drain port 11c of the tank 11, rendering the drain inoperable. By repeating the above-mentioned operations in sequence, drainage operations are automatically performed in each cage as appropriate.

As described above, according to the present invention, water can be drained without sprinkling water by opening the valve when each cage stops at the car loading/unloading position, so that water can be drained without sprinkling water. No impact noise is generated. Further, since it is sufficient to simply provide a drainage hole in the cage floor, cleaning can be performed extremely easily. Furthermore, since the opening/closing operation of the valve can be carried out by directly transmitting the moving operation of the rod, there is an advantage that a complicated conversion drive mechanism is not required.
