[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage type multi-level parking apparatus in which a pallet on which a vehicle is placed is suspended in a pit by a chain so as to be lifted and lowered.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional parking apparatus of this type is provided with sprockets 2a, 2b, 2c and 2d at four corners of a pallet 1 for mounting a vehicle, and two chains 3a and 3b. Of the sprockets, the sprockets 2a and 2c and 2b and 2d which are adjacent to each other are stretched in parallel and in parallel, and one ends of both chains 3a and 3b are connected to root stoppers 5a and 5b provided on one side of the upper part of the pit 4, respectively. Fix it,
The other end is directly wound and connected to a coaxial shaft 6 provided on the other side of the upper part of the pit 4, or roots 8a and 8b are attached through sprockets 7a and 7b attached to the coaxial shaft 6,
The pallet 1 is moved up and down in the pit 4 by rotating the coaxial shaft 6 by the drive motor 9. Therefore, there is a problem that a relatively long coaxial shaft is required, a large installation space is required, and installation work on site becomes difficult, resulting in high cost.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It eliminates the need for the coaxial shaft used conventionally, requires a small installation space, and is easy to install. The purpose of the present invention is to provide a two-stage multi-level parking device that can reduce costs.

[0004]

A two-stage multi-level parking apparatus of the present invention that achieves the above object is provided with sprockets at four corners of a pallet, and two root stop portions are provided on one side at the upper position of the pit. Two upper fixed pulleys are installed on the side, two lower fixed pulleys are provided at the lower position of the pit in correspondence with the upper fixed pulleys, and stationary pulleys are provided near the lower fixed pulleys. Of the above-mentioned sprockets are stretched in a hooked manner over the sprockets diagonally located to each other, one end of each chain is connected and fixed to the root stop, and the other ends of both chains are fixed to the upper part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the schematic drawings. In the figure, reference numeral 1 denotes a pallet for mounting a vehicle, which is formed into a substantially rectangular plane shape having a size capable of mounting one vehicle, and the chains 3a, 3b are suspended at four corners thereof. Install the sprockets 2a, 2b, 2c, 2d.

On the other hand, the pit 4 for mounting the pallet 1 so as to be able to move up and down may be formed by digging down the ground g as shown in FIG. 2, or a pillar so as to surround the pallet 1 on the ground g. May be installed upright.

At the upper position of the pit 4, two root stop portions 5a and 5b are formed on one side (for example, the right side) of the pit 4, and two upper fixed pulleys 10 are formed on the other side (for example, the left side).
Install a and 10b.

At the lower part of the pit 4, two lower fixed pulleys 11a and 11b are installed on the other side (for example, the left side) at positions corresponding to the upper pulleys 10a and 10b.
A stationary pulley 12 is provided near each of the lower fixed pulleys 11a and 11b.
a and 12b are installed, a transmission sprocket 13 is installed near one stationary pulley 12b, and the drive motor 9 is connected to the transmission sprocket 13 via a transmission chain 14.

Thus, the two chains 3a and 3b are
Each sprocket 2a, 2b provided at the four corners of the pallet 1
Of the 2c and 2d, the sprockets 2a and 2d, 2b and 2c, which are located diagonally with respect to each other, are stretched in the form of a hook. That is, one chain 3a is attached to the sprocket 2
The chain 3b is suspended over a and 2d, the other chain 3b is suspended over the sprockets 2b and 2c, and both chains 3a and 3b are crossed in the form of a hook with the bottom of the pallet 1.

Then, one ends of both chains 3a and 3b are connected and fixed to root stoppers 5a and 5b provided on one side above pit 4, respectively, and the other ends of both chains 3a and 3b are connected to the other side above pit 4. Through the fixed pulleys 12a, 12b, which are installed from the upper fixed pulleys 10a, 10b provided on the lower fixed pulleys 11a, 11b below the lower fixed pulleys 11a, 11b,
The pallets 1 are connected and fixed to the root stoppers 15a and 15b formed on the bottom of the pallet 1.

That is, one chain 3a has a sprocket 2a and a sprocket 2d from the root stop 5a at one end.
→ Upper fixed pulley 10b → Transmission sprocket 13 → Lower fixed pulley 11b → Stationary pulley 12a → Pallet 1 bottom root stop
Connected and fixed over 15a, and the other chain 3b
Is fixedly connected from the root stopper 5b at one end to the sprocket 2b → sprocket 2c → upper fixed pulley 10a → lower fixed pulley 11a → stationary pulley 12b → root stopper 15b at the bottom of the pallet 1.

When the drive motor 9 is operated to rotate the transmission sprocket 13 in the clockwise direction via the transmission chain 14, both chains 3a and 3b move in the directions of arrows m1, respectively. When the pallet 1 rises and, conversely, the transmission sprocket 13 is rotated counterclockwise, both chains 3a and 3b move in the directions of the arrows m2, and the pallet 1 descends.

At this time, with respect to the front and rear inclination of the pallet 1, even if only the sprocket 2d on which one chain 3a is suspended is going to go up first, the other chain 3b is the root fixing portion 15b at the bottom of the pallet 1 near it. Since the other chain 3b is pulled together and the sprocket 2c also rises by the same distance, the pallet 1 does not tilt back and forth.

Regarding the inclination of the pallet 1 to the left and right, the entire chain 3a, 3b is always braked in a tensioned state by the drive motor 9 having an electromagnetic braking function or a separate braking means. Does not tilt left or right.

The chains 3a and 3b have a chain structure only at the portions meshing with the sprockets 2a to 2d and the pulleys 10a to 13b and 13, and the other portions are wire ropes, or the whole is a wire rope. It is also possible to do so.

[0016]

EFFECTS OF THE INVENTION Since the two-stage multi-story parking system of the present invention is constructed in this way, it is of course possible to raise and lower the pallet in a well-balanced state while holding it horizontally in the pit, and to use it with the conventional system. The coaxial shaft that was used is no longer required, and as a result, a small installation space is required, and installation work is easy and cost can be reduced.
