Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multilevel parking system that accommodates a plurality of vehicles in the vertical direction to effectively utilize space.

This type of multi-level parking system is designed to accommodate multiple parking pallets.
A type of unloading device that rotates vertically in sequence is known, but with this type, each time a vehicle enters or exits, the entire parking pallet is completely parked until the designated parking pallet or empty parking pallet reaches the lowest position. It is necessary to rotate the pallet.

In view of the above-mentioned circumstances, the present invention aims to provide a multi-story parking lot in which only the necessary parking pallets can be moved to the vehicle entrance/exit when necessary. is a pallet loading area with multiple stages of pallet loading sections, a pair of A lowering bars are installed at the front and rear, and a pallet transporting section movable in the left and right direction is attached to the inner circumference of each lifting bar. A parking pallet is placed between the pallet transport sections of the lifting bar, and the pallet M is raised and lowered, and the pallet transport section is synchronously moved in the left and right direction at a predetermined position to move it in and out of a predetermined pallet placement section. It is configured as follows.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

The illustrated multi-story parking lot consists of pallet loading areas 3 and 3 on the left and right sides of a frame that is connected by four wooden pillars 1 and 2 horizontal beams in multiple tiers downward. At the same time, the center is a pallet lifting area 4, and a pair of lifting bars 5, 5 which are movable in the vertical direction are attached to the front and rear ends of the frame. A pair of front and rear columns 6 with supporting rods 6a... protruding inward.
The conflict 6 has been fixed to the horizontal beam 2... and vertically bent, the front and rear pillars 6 and 6
The parking pallet 7 is placed between opposing support rods 6a and 6a, respectively (see FIGS. 1 to 3).

Each lifting bar 5 is guided up and down by a pair of left and right lifting guides 8, 8 each consisting of two I-shaped cross-section columns 8a, 8b vertically extending along the horizontal beams 2. On the back side, there are four horizontal rocking regulating rollers 9a, top, bottom, left and right.
...and a pair of upper and lower vertical swing regulating rollers 9b, 9
A pair of left and right y lowering roller portions 9φ9 each having a diameter b are attached. Each swing regulating roller 9a... is an I-shaped support 8a.
- Each guide roller 9 comes into contact with the opposing inner circumferential groove side wall of 8b.
b is configured to roll in contact with the lower wall of the outer circumferential groove of the I-shaped support 8a (see FIGS. 4 to 7).

The left and right lifting rollers 9 and 9 of each lifting bar 5 have sprockets (lla and lla) attached to the top of a piston rod 11 that has one end 10a fixed to the top horizontal crosspiece 2'' and that extends and contracts in the vertical direction. The other ends 10b, 10b of a pair of chains 10φ10 are fixed to each other through sprockets 12, 12 installed on the top horizontal beam 2, respectively, and are configured to move the lift bar 5 up and down in accordance with the expansion and contraction movement of the piston rod 11. (See Figures 7 to 9).

A horizontal groove 13 is formed in the inner circumferential portion of each lifting bar 5, into which a pallet conveying section 14 is fitted so as to be slidable in the left and right direction. This pallet conveying section 14 has a pair of idling rollers 14a that contact the upper and lower inner wall surfaces of the lateral groove 13 at both ends, and a pair of idling rollers 14b that contact the inner wall of the lateral groove 13 adjacent to these. . Both ends of the wound chain 16 are fixed (see Figures 1O to 11). Incidentally, one sprocket 15 is rotationally driven by a drive source (not shown), and the chains 16 of the front and rear lifting bars 5, 5 are
They are connected to rotate synchronously via a central connecting rod 17 (see Figures 4 and 7).

Each parking pallet 7 is constructed by connecting a pair of left and right groove-shaped vehicle mounting portions 7a, 7a with a plate 7b, which is inclined upwardly in the front and back and has a mesh-like non-slip finish on its surface.
A support rod 6a and flanges 7c and 7c for mounting the pallet conveying section 14 provided on the inner circumference of the lifting bar 5 are formed on the front and rear ends (see FIGS. 12 and 13).

In the multilevel parking system configured as described above, the pair of piston rods 11 and 11 are simultaneously extended and contracted to raise and lower the elevator bar 5.
- 5 is moved up and down, and near a predetermined parking pallet placement position, the pallet conveying parts 14 are slid in the left and right direction by the rotational drive of the sprocket 15, and the flange portion of the predetermined parking pallet 7 is moved. After positioning it on the bottom surface of 7C/70,
By further raising the elevator bar 5 a little further, the parking pallet 7 is released from the support rods 6a, 6a, and in this state, the sprocket 15 is reversely moved to slide the pallet conveying parts 14, 14 to the center. Then, the parking pallet 7 is moved to the central lifting area 4. Next, piston rod 1
By extending and retracting the lift bars 5 and 11, the lift bars 5 and 5 are lowered to the lowest position to move the vehicle in and out. After the vehicle has entered and exited, the parking pallet 7 is returned to the predetermined placement position by following the procedure in the reverse order as described in j;.

As described above, according to the multilevel parking apparatus according to the present invention, only the necessary parking pallets can be moved to the vehicle entrance/exit when necessary.
