Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents lateral vibration when moving up and down each vehicle-mounted stand in a multi-story car park, and even if an endless chain for vertically moving the vehicle-mounted stand is cut in the middle, it is mounted on the vehicle. It is about making sure that the table does not drop.

2. Description of the Related Art Japanese Patent Application No. 2-257358 proposed by the applicant is known as a multi-storey parking lot. The Japanese Patent Application No. 1 is a rectangular frame in which two horizontal beams are provided between two columns.
The frame and the second frame are arranged vertically with a parallel interval, and chain wheels are attached to the inside of the four corners of the square frames of the first and second frame, and the chain piece and the chain are attached to the chain wheel. The chain roller is interposed between the chain pieces, and two sets of endless chains are mounted so as to rotate in synchronism with the mounting shaft of the roller bearing fitting projecting inward from the middle of the chain pieces. Then, a plurality of suspension shafts are provided between the respective mounting shafts, an in-vehicle basket is suspended on each suspension shaft, and a part of the chain roller and the roller bearing is laterally mounted between the chain wheels. It describes a multi-story car park device characterized in that it is supported in contact with rails.

[0003]

However, according to the above-mentioned Japanese Patent Application, since the plurality of suspension shafts provided between the two sets of the endless rotary chains have the pivot points, the car cage is suspended. , The car cage has a problem that it swings laterally from the upper pivot point as a base point when it moves up and down. In addition, the two endless rotary chains have a problem that if a tear or the like occurs in the middle, they will be dropped together with the car basket, which is dangerous.

[0004]

According to the present invention, two sets of endless rotary chains are stretched along the front frame and the rear frame with the front frame side being high and the rear frame side being low. A suspension arm extending upward is provided at one end, and a pivot shaft projecting in a plane is provided at the other end. The suspension arm at one end of the vehicle mount is suspended from the endless rotary chain on the higher position side, and the pivot shaft at the other end is formed as described above. An inner member and an outer member that are pivotally attached to the lower endless rotary chain to prevent lateral shake when the vehicle-mounted platform moves up and down, and that maintain the two endless rotary chains in a stretched shape and regulate them. It is intended to solve such a problem by surrounding it with a guide rail made of.

Embodiments Embodiments will be described below with reference to the drawings.

Upper struts 1a, 1b and one or several intermediate struts 2
A crane wire hook (not shown) is installed in the hook hole 5 provided in the middle of the top cross beam 4a that carries the lower columns 3a and 3b into which the a and 2b are inserted so that they can be extended, and connects the upper columns 1a and 1b. The intermediate support columns 2a and 2b and the upper support columns 1a and 1b are sequentially drawn out from the lower support columns 3a and 3b by the procedure of hanging and hanging up to assemble the front frame 6 and the rear frame 7 vertically. Reference numeral 8 is a stopper member between the columns, and 9a and 9b are extraction preventing claws.

As shown in FIG. 1, the front frame 6 is vertically assembled with respect to the rear frame 7 for one vehicle or more, and after a required reinforcing beam 10 is stretched, the front frame 6 and the rear frame 7 are assembled. A guide rail 11 composed of an inner member 11a and an outer member 11b is stretched on the inner surface, and a chain is provided in which a chain roller 12d for rotation and rotation is provided between the chain piece 12c and the chain piece 12c. Endless rotation chain with endless bundling
12a and 12b. Since the endless rotating chains 12a and 12b are surrounded by the guide rail 11 with a slight gap,
Even if there is a tear in the middle, the chain will not fall because there is no place to go. The guide rail 11 has a curved upper portion as shown in FIG. 2 to eliminate the need for chain wheels at the corners.

The endless rotating chain 12a on the front frame 6 side is extended from an intermediate height apart from the ground surface to the top of the front frame 6 for one car or more, and the endless rotating chain on the rear frame 7 side.
12b will be stretched from near the surface of the earth to the top, which is one step lower than the front frame 6.

The vehicle mount 13 has an arch-shaped suspension arm 14 extending upward at one end, and a pivot 15 projecting in the same plane from the vehicle mount at the other end, and a short shaft projectingly attached from the upper end of the suspension arm 14. 14a is an endless rotating chain 12a on the front frame 6 side
The pivot shaft 15 is pivotally connected to the endless rotary chain 12b.

Reference numeral 16 is a power transmission mechanism for rotating the endless rotation chain 12a, 17 is a transmission shaft for rotating the endless rotation chain 12b in synchronization, 18 is the same transmission mechanism, and 19 is a lower part. It is a chain wheel attached to the horizontal beam 4b.

The automobile A comes in and goes out from the front frame 6 side and is mounted on the vehicle base.
It rides on the top 14 and is moved up by the rotation of the endless rotation chains 12a and 12b to make a three-dimensional parking.

[0012]

According to the present invention, one end of the vehicle-mounted base is suspended and pivotally attached to the one endless rotary chain by the suspension arm, and the pivot end protruding in the same plane from the other end of the vehicle-mounted base is rotated endlessly on the other side. Since it is pivotally attached to the motion chain, the lateral shake caused by the suspension fulcrum is canceled by the lateral shake prevention stress with the pivot end on the other side as the base point, so that the lateral shake that occurs when the vehicle mount moves up and down is eliminated. Produce an effect.

Further, since the endless rotary chain is surrounded by the guide rail that holds and regulates the stretched shape composed of the inner member and the outer member, the endless rotary chain is stretched even if it tears in the middle. Since the shape is maintained, the effect that the vehicle-mounted stand is not dropped is produced. Further, since the endless rotary chain has the stretched shape and the rotary path secured by the guide rails, the chain wheel is not required except for the power transmission portion, so that the facility cost can be reduced.
