Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multilevel parking facility, and more specifically,
The cage is suspended from a pair of endless chains that are wound around and driven by multiple sprockets supported by a base, and the endless chain has a vertical lifting section and a meandering horizontal running section with multiple upper and lower stages. The present invention relates to a multilevel parking facility that is equipped with and accommodates.

[Prior Art] As a facility for parking a large number of vehicles such as automobiles on a narrow piece of land, there is a system in which the vehicles are loaded into a cage and the cage is moved in the air to park in a multi-dimensional manner. Conventional multilevel parking facilities of this type are:
The cage is suspended from a chain that circulates on an elliptical track with a long span in the vertical direction. This type of facility can park several dozen vehicles in a parking space for three to four vehicles. However, since approximately half of the total weight of the cage and the vehicle loaded thereon is loaded onto the chain, it is necessary to strengthen the chain and the base that supports the chain. Therefore, there was a problem that the equipment cost per unit increased.

Furthermore, in conventional parking facilities of this type, it is not possible to change the direction of the vehicle within the cage. Therefore, in the case of equipment in a building that has an entrance on one side, a turntable is installed in front of the cage at the loading/unloading position in order to facilitate loading and unloading into and out of the parking lot and cage. The vehicle was placed on the road and the direction was changed arbitrarily. Providing such a turntable increases equipment costs and requires additional space.

Therefore, in recent years, it has been proposed that the running route of the chain is folded horizontally and formed in multiple stages to improve accommodation efficiency, and that a turntable is installed on the entrance surface of the vehicle.

[Problems to be Solved by the Invention] In the above-mentioned multi-story parking facility, the front and rear cages collide at the folded part of the horizontal running section of the chain, so it is necessary to provide notches at the upper and lower corners of the cage. Even if consideration is given to the above, there are significant restrictions on the spacing between the hanging devices, and the number of devices that can be accommodated within the circulation route is limited. Therefore, if the sprocket for folding and detouring the chain is made larger, the overall height will increase, and only the outer periphery of the sprocket is effective, increasing cost. Reducing the hanging spacing of the cages in the horizontal section requires a complex configuration.

Furthermore, since the chain that is constructed with the folded portions at both ends supports the weight of the cage and the vehicle, it is necessary to strengthen the structure of the chain. Therefore, in order to avoid this, it has been proposed to use a chain only for driving and erect a separate rail to support the weight of the traveling cage, but this multi-tiered rail is of the type that suspends the cage. However, since the cage cannot be avoided and the cage oscillates, and it is determined by the distance between the turning and horizontal running paths, an auxiliary rail is required in the middle corresponding to the height of the cage itself.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has been devised to solve the drawbacks of the prior art. In a multi-story parking facility in which a cage is suspended from a pair of driven endless chains, and a vertical lifting section and a meandering horizontal running section with multiple upper and lower stages are formed on the endless chains, a large number of vehicles can be loaded and accommodated. The endless chain has a number of cages with wheels attached to the bottom frame suspended at equal intervals, and the folding sprocket at the end of the horizontal running section has two upper and lower stages corresponding to the height of the cages. At the same time, the lower sprocket is positioned slightly outward to cause the endless chain to run diagonally, and the wheels are mounted on the base body along each horizontal running section of the endless chain except for the top stage. The object of the present invention is to provide a circulating multi-level parking facility characterized by having abutting rails constructed therein. With the present invention, although it is a multi-story parking facility with a normal configuration, a large number of cages can not only turn and form travel routes without being subject to restrictions on the front and rear suspension intervals, but also reduce the load on the chain. This has completed a multi-level parking facility with a simple configuration.

[Example] The present invention will be described below based on an example shown in the accompanying drawings. FIG. 1 is a front view schematically showing the present embodiment, and FIG. 2 is a perspective view showing a cage and a jacking device at a loading/unloading position of a vehicle.

The basic structure of the multi-level parking facility of the present invention is that a pair of endless roller chains (hereinafter simply referred to as chains) 10 are stretched in parallel at a predetermined front-rear interval and accommodated on the base of a frame (not shown). A large number of cages 20 carrying vehicles are suspended at appropriate intervals,
It is wound and driven around a plurality of sprockets 12, 12, . . . rotatably mounted on a base body.

The chain 10 consists of a vertical lifting section and a horizontal running section having a plurality of upper and lower stages and having a long span in the horizontal direction, and the horizontal running section is turned back and circulated in a meandering manner for each sprocket 12. The sprocket 12 of each folded portion is connected to the upper sprocket 12,
The lower sprocket 12' is arranged one above the other, and the vertical interval is approximately equal to the height of the cage 20, and the lower sprocket 12' supports its spindle outward from the upper sprocket 12. The folded chain 10 is slanted outward in this portion.

Reference numeral 14 denotes a drive sprocket rotated by an electric device (not shown), and the rotation of this drive sprocket 14 allows the chain 10 to freely circulate in both directions. The direction is changed from vertical to horizontal. The sprockets 16, 16, . The height of the folding portion corresponds to the height of the cage 20 above the loading/unloading surface of the vehicle.

The cage 20 corresponds to the size of the loaded vehicle, and as shown in FIG. 2, it has a pair of front and rear side frames 22, a rectangular bottom frame 24, and a bottom plate placed on the bottom frame 24. 26, an axle 28 connecting the upper part of the side frame 22, and two wheels each attached to the bottom surface of the bottom frame 24 in a position parallel to the side frame 22, for a total of four wheels. 10, 10 are installed at equal intervals and parallel to each other, and are suspended. Bottom plate 26
is removably placed on the top surface of the bottom frame 24, and the top surface is designed to prevent the vehicle on which it is mounted from falling.
The center is hollow. The size of this bottom plate 26 is such that it can rotate inside a set of side frames 22.
The length of the diagonal line is shorter than the interval between the side frames 22 located on the diagonal line of the cage 20. Furthermore, the lower surface of the periphery of the bottom plate 26 conforms to the slope formed on the upper surface of the periphery of the bottom frame 24, making the upper surfaces of both flat and even, making it easy for a vehicle to enter the vehicle.

On the other hand, along the running route of the chain 10 excluding the uppermost horizontal running part, the rail 3 supported by the base body
2, 32 are provided, and contact the wheels 30, 30 on the lower surface of the cage 20 in the horizontal running section directly above,
It supports the cage 20. Therefore, rail 32
are missing in the loading/unloading section of the vehicle, and rails 34 are laid in the loading/unloading section formed by folding down.

Next, a jacking device 40 for operating the vehicle is installed and buried on the floor or underground at the loading/unloading location of the vehicle. This jacking device 40 includes a piston rod 42 that projects upward, and a base plate that is horizontally fixed to the tip of the piston rod 42 and that abuts and supports the bottom plate 26 of the cage 20. Further, this jacking device 40 is formed so that the bottom plate 26 can be rotated at least 180 degrees while the bottom plate 26 is pushed up from the bottom frame 24. As this rotation mechanism, a known mechanism such as a mechanism for rotating the piston rod 42 or a cylinder is used.

[Function] The function of the multilevel parking facility configured as described above will be explained based on its usage.

When parking, the empty cage 20 closest to the loading/unloading position is circulated to the loading/unloading position by actuation of a control device, as is well known in conventional multi-level parking facilities. . The vehicle is driven forward into this empty cage 20 and all tires are placed in the recesses of the bottom plate 26. When the driver pulls the handbrake and gets out of the vehicle, the jack device 40 is operated to project the piston rod 42, push the bottom plate 26 up from the bottom frame 24, rotate it 180 degrees, and then retract it. By this operation, the vehicle inside the cage 20 is turned over by 180 degrees, with the front facing forward, and loading of the vehicle into the cage 20 is completed. When pulling out a parked vehicle, the above-described operations can generally be performed in reverse.

During the circulation movement of the cages 20 described above, each cage 20 successively passes through the folded portion of the horizontal running section, but at this time, the sprockets 12, 12' are arranged above and below in accordance with the height of the cage 20. Since the chain 10 is moved diagonally, the front and rear suspended cages 20 do not collide with each other at this portion.

In addition, since the intervals between the horizontal running parts are formed corresponding to the height of the cage 20, and each rail 32 is also constructed correspondingly, the wheels 30 provided at the lower part of the suspended cage 20 are connected to the rails 32. abut, and therefore,
The weight of the cage 20 and the vehicle is supported by the rails 32 without becoming a load on the chain 10.

[Effects of the Invention] In short, the present invention has a cage suspended from a pair of endless chains that are wound around a plurality of sprockets supported by a base and driven, and a vertical lifting section and a plurality of upper and lower stages of the endless chain. In a multilevel parking facility in which a meandering horizontal running section is formed to accommodate a large number of vehicles, the endless chain has a large number of cages with wheels attached to the bottom frame suspended at equal intervals. The folding sprocket at the end of the horizontal running section is pivoted in two stages, upper and lower, corresponding to the height of the cage, and the lower sprocket is positioned slightly outward to allow the endless chain to run diagonally. , Since the base body has rails on which the wheels come into contact along each horizontal running part of the endless chain except for the top stage, although it is a multi-story parking facility with a normal basic configuration, there is no turn-around part. The sprockets in the cage are arranged vertically according to the height of the cage, and the chain is moved diagonally, so there is a margin between the front and rear suspended cages, and the side frames of their adjacent side frames are arranged at an angle. There is no need to cut corners to a particularly large extent or use large sprockets to make a detour, and the cage runs extremely smoothly. In addition, the intervals between the horizontal running parts are formed to correspond to the height of the cage, and each rail is also constructed correspondingly, so that the wheels provided at the bottom of the suspended cage come into contact with the rails, and therefore , the weight of the cage or vehicle does not become a load on the chain.
