The other end of respective chains is fixed 3a-3d to the lower face of the four corners of the pallet and either of respective chains is connected to a drive motor M.

Description

Detailed Description of the Invention

[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 or a wire rope and lifted and lowered.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional parking device of this type has two chains provided with sprockets 10a, 10b, 10c and 10d at four corners of a pallet A on which a vehicle is placed.
Of the sprockets, the sprockets 11a and 11b are stretched in parallel over the adjacent sprockets 10a and 10d and 10b and 10c in parallel, and one end of both chains 11a and 11b is fixed to the upper side of the pit B. Connect and fix each to 12b,
The other end is directly wound and connected to a coaxial shaft 13 provided on the other side of the upper part of the pit P, or roots 15a, 15b are passed through sprockets 14a, 14b attached to the coaxial shaft 13.
The pallet A is moved up and down in the pit B by rotating the coaxial shaft 13 by the drive motor M. Therefore, a relatively long coaxial shaft is required, and thus a large installation space is required, and
There was a problem that the installation work on site was difficult and costly.

[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 facilitates installation work. It is intended to provide a two-stage type multi-level parking device capable of reducing the cost by using the above, and capable of stably moving up and down the pallet without the guide rail of the pallet.

[0004]

A two-stage multi-level parking apparatus of the present invention that achieves the above object suspends a pallet on which a vehicle is mounted in a pit with a chain (or wire rope, the same applies hereinafter). In a two-level multi-level parking device that is lifted up and down, root one end of the chain on the upper surface of the four corners of the pallet,
Four upper fixed pulleys are installed in the upper position of the pit corresponding to the four corners of the pallet, and four lower fixed pulleys are installed in the lower position of the pit corresponding to the four corners of the pallet and in the vicinity of each lower fixed pulley. A stationary pulley is placed on each of the chains, and each chain is erected from the upper fixed pulley located directly above the stationary pulley to the stationary pulley located directly below the stationary pulley, and two chains arranged on one side of the pallet inside the chain. The chains are respectively installed on the lower fixed sheaves diagonally located, and the two chains arranged on the other side of the pallet are erected on the lower fixed sheaves located on one side of the pallet. The other end is fixed to the lower surface of each of the four corners of the pallet, and a drive motor is connected to any one of the chains. A wire rope may be used instead of the chain, or only the portion meshing with each pulley may have a chain structure and the other portions may be wire ropes. In the following description, the wire rope is simply referred to as a chain.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to a schematically shown picking surface. In the figure, A is a pallet for placing a vehicle, which is formed in a substantially rectangular plane shape having a size that allows one or a plurality of vehicles to be placed, and each chain has an upper surface at each of four corners. 1a, 1
Roots 2a, 2b, 2 at one end of b, 1c, 1d respectively
c, 2d, and each chain 1a-
The other end of 1d is root-stopped 3a, 3b, 3c, 3d, respectively.

On the other hand, the pit B for mounting the pallet A so that it can be moved up and down may be formed by digging down the ground G as shown in FIG. May be installed upright.

Then, at the upper position of the pit B, four upper fixed pulleys 4a, 4 are provided corresponding to the four corners of the pallet A.
b, 4c, 4d are installed. That is, the upper fixed pulleys 4a to 4d are installed directly above the four corners of the pallet A, respectively.

At the lower position of the pit B, four lower fixed pulleys 5a, 5b, corresponding to the four corners of the pallet A,
5c and 5d are installed and each lower fixed pulley 5a-5
Stationary pulleys 6a, 6b, 6c, 6d are arranged near d.

Thus, the four chains 1a to 1b are respectively installed from the upper fixed sheaves 4a to 4d located directly above to the stationary sheaves 6a to 6d located directly below the upper sheaves 4a to 4d, and one side of the pallet A therein. Two chains 1a and 1b arranged on the left side (for example, on the left side) are respectively fixed to the lower fixed sheaves 5c and 5d located on the diagonals thereof.
And the two chains 1c and 1d arranged on the other side of the pallet A (for example, on the right side) are attached to one side of the pallet A, respectively. Lower fixed pulley 5 located adjacent to
They are installed on b and 5a and arranged in parallel on the lower surface of the pallet A.

The other end of each chain 1a-1b is
Lower surface of four corners of pallet A, specifically, lower fixed pulleys 5a-
Rooted on the lower surface of the four corners of pallet A located immediately above 5b 3
a, 3b, 3c, 3d, and the drive motor M is connected to any one of the chains 1a to 1b (chain 1a in the illustrated example).

Then, when the driving motor 9 is operated to rotate the transmission sprocket, which also serves as the lower fixed pulley 5c, in the counterclockwise direction, all the chains 1a to 1d move in the direction of the arrow Y and the pallet moves. A rises, and on the contrary, if the transmission sprocket is rotated clockwise, pallet A
Descends.

At this time, the roots 2 are fixed on the upper surfaces of the four corners of the pallet A.
a to 2d, one end of the chains 1a to 1d, and the chains 1a to 3d root-fixed to the lower surfaces of the four corners of the pallet A.
The other end of 1d is different from each other (for example, the other end of the chain 1a whose one end is rooted 2a on the upper surface of the pallet is the back side where the one end of the chain 1c is rooted 2c (the lower surface of the pallet).
The other end of the chain 1d is root-stopped 3d on the back side (bottom surface of the pallet) where the chain 1a is root-stopped 3a and one end of the chain 1a is root-stopped 2a. Therefore, each of the chains 1a to 1d cannot move independently. It is impossible, and therefore, the pallet A does not tilt forward and backward and left and right as the pallet A moves up and down.

EFFECTS OF THE INVENTION Since the two-stage multi-level parking apparatus of the present invention is constructed in this way, the coaxial shaft used in the conventional apparatus is not required, a small installation space is required, and the construction is simplified. The work becomes easy and the cost can be reduced as a whole.

Moreover, since it is mechanically impossible to independently move the four chains that suspend and support the pallet, the pallet is held horizontally in the pit even without the pallet guide rails. Therefore, it is possible to lift and lower in a well-balanced manner, and thus it is possible to expect stable, safe and reliable lifting and lowering of the pallet.
