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 11
b), and the other end is fixed to the tank 11).For example, the bottom of this tank 11 is deeper toward the center of the cage floor, and the bottom is deeper toward the tip. It has a tapered structure with a shallower bottom.
As shown in FIG.
c is provided in an oblique direction so as to descend downward toward the tip of the tank 11. Reference numeral 13 denotes a hollow rod supported slidably in the front-rear direction (left-right direction in FIG. 5) via brackets 13a and 13b on the back surface of the floor 10 of the cage, and a spring seat 15 is provided at the tip. Brackets 13a and 13b
The lower surface of piece A of the guide rail 11c provided on the tank 11 is supported in the intermediate part between the tanks 11 and 11.
A roller 13c is attached to support the roller 13c.
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 in the center of the rod, and the spring seat 19 of the rod 17 and the spring seat 15 of the rod 13 are fixed to each other.
A spring 20 is inserted between them.

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 13c of the rod 13
The tank 11 moves horizontally in the direction of arrow A while supporting the lower surface of piece A of the guide rail 11c provided on the guide rail 11c and supporting the weight of the tank 11. Conversely, the tank 11 moves horizontally in the direction of arrow A while supporting the lower surface of piece A of the guide rail 11c provided on the rod 13. As it moves, it moves while maintaining contact with the roller 13c, so it rotates counterclockwise around the shaft 11b due to its own weight, tilts as shown by the two-dot chain line in FIG. Discharge from the area all at once.

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, and the rod 13 also moves in the opposite direction to that described above.
The roller 13c is the guide rail 1 of the tank 11.
While pushing up the lower surface of piece A in 1c,
By being guided in contact with this lower surface and moving horizontally in the direction of arrow B, the tank 11 is moved to the bracket 11a.
Rotate clockwise around the center to return to the original state 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 stops at the car loading/unloading position, so water can be drained without sprinkling water, and while the cages are being circulated. 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.
