[Problems to be solved by the invention]
By the way, in recent years, in the automobile industry, instead of low-roof vehicles with a vehicle height of 1550 (mm) or less represented by sports cars and vehicles called sedans, which have been mainstream until now, according to consumer needs, High roof vehicles having a vehicle height of 1550 [mm] or more typified by so-called SUV (Sport Utility Vehicle) and vehicles called RV (Recreational Vehicle) have become mainstream. In particular, among these high roof cars, in particular, a mid roof car represented by a so-called minivan having a vehicle height of about 1700 [mm] has gained popularity.
[0010]
However, in the existing vertical circulation parking apparatus having such a configuration, the effective height h1 of the cage 6 is 1550 [mm] or less within the vertical pitch P of the cage 6, as shown in FIG. Since it is often set for a vehicle having a vehicle height, it is difficult to store a mid-roof vehicle having a vehicle height of about 1700 [mm] in such an existing cage 6. was there.
[0011]
In addition, a user who hates the existing vertical circulation parking device, which is difficult to store a mid-roof vehicle, refuses to use it, which may reduce the operating efficiency of the vertical circulation parking device. It was.
[0012]
Therefore, as one of the solutions to this problem, when constructing a new vertical circulation parking device, the vertical circulation parking system is arranged with cages for mid-roof vehicles that can also store these mid-roof vehicles. Although the equipment is being constructed, if the existing vertical circulation parking device is rebuilt to a vertical roof parking device for mid-roof vehicles, the new vertical circulation parking device will be used for the period of time when the existing vertical circulation parking device is torn down. There is a problem that it takes a lot of construction costs to complete, and there is still an inadequate problem that takes time to complete for the period of demolishing the existing parking device in this way, and in addition to this, the completion of a new vertical circulation parking device There was also a problem that the business as a parking device had to be suspended during the period up to.
[0013]
In addition, in most of the existing vertical circulation parking devices, it is difficult to store a mid-roof vehicle even though the building age is shallow and it can still operate sufficiently as a parking device. For the reasons alone, discarding most of the equipment and rebuilding it into a new parking equipment was also a waste of resources.
[0014]
The present invention has been made in view of the above-described problems. A cage that can load not only a low roof vehicle but also a mid roof vehicle, and a variety of vehicles can be accommodated by using such a cage. It is an object of the present invention to provide a mechanical parking device that can significantly improve the operation efficiency and a manufacturing method of the mechanical parking device that can minimize the construction cost and time of such a mechanical parking device. .
[0015]
[Means for Solving the Problems]
In order to solve this problem, the present invention employs the following means.
[0025]
According to the first aspect of the present invention, the upper sprocket is rotatably supported at the upper position in the parking lot structure, while the lower sprocket is rotatably supported at the lower position in the parking structure. By hanging an endless chain around the lower sprocket, suspending a plurality of vehicle loading cages at predetermined arrangement intervals in the longitudinal direction of the endless chain, and rotating and driving at least one of the upper sprocket or the lower sprocket In the manufacturing method of the mechanical parking lot in which the endless chain is driven and the plurality of cages are circulated, a cage in which the vehicle is not loaded among the plurality of cages is set to an effective height of a portion on which the vehicle is loaded. when sequentially replaced with high new cage than Saga existing cages, to reduce the overall length packed with the endless chain, the upper The position of the tire tread portion of a new cage is characterized in that to match the position of the floor face of the entry and leaving port of the vehicle in the parking structure. According to this method for manufacturing a mechanical parking device, the position of the cage is attached to the endless chain by pulling the position of the lower sprocket upward in the parking structure without changing the position of the upper sprocket by pinching the endless chain.

[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0027]
1 (a) and 1 (b) are schematic overall configuration diagrams showing an embodiment of a cage according to the present invention. In FIG. 1, reference numeral 10 denotes a cage according to the present invention as a whole, which is a loading table 10a which is a loading means on which a vehicle (not shown) is mounted, and a suspension means fixed to both front and rear sides of the loading table 10a with respect to the vehicle entry direction. The suspension ring 10b includes a cage suspension shaft 10c which is a shaft disposed so as to penetrate the upper portion of each suspension ring 10b. The cage suspension shaft 10c is supported by a sliding bearing K provided on the suspension ring 10b so as to be rotatable about its axis. Incidentally, ST in the figure indicates a tire stop.
[0028]
In this cage 10, a bent portion 10ca that is bent or bent downward is provided between the suspension rings 10b on the front and rear sides of the cage suspension shaft 10c. For example, the cage 10 is a vertical circulation parking that is a mechanical parking device. When used in the apparatus, as shown in FIG. 2 (a) in which parts corresponding to those in FIG. The cages 10 adjacent to each other in the circulation direction in the parking apparatus (that is, the loading platform 10a of the upper cage 10 and the cage suspension shaft 10c of the lower cage 10) interfere with each other in advance. As a result, the position of the loading platform 10a of these cages 10 can be made lower than in the prior art.
[0029]
Thereby, in this cage 10, since the effective height h2b of the part on which the vehicle is loaded on the loading table 10a can be set to about 1750 [mm], the conventional effective height h1 (about 1550 [mm]). As a result, not only conventional low-roof vehicles but also mid-roof vehicles and accompanying heavy vehicles can be loaded.
[0030]
Further, when such a cage 10 is used in a vertical circulation parking device, the pitch P of each cage 10 in the vertical direction is maintained in the same manner as before (that is, the number of accommodated vehicles is maintained). Since the effective height h2b can be secured greatly, not only low-roof vehicles but also mid-roof vehicles and accompanying heavy vehicles can be accommodated, thus increasing the number of users corresponding to various vehicles. The operating efficiency can be greatly improved.
[0031]
Further, the loading platform 10a is provided with a tire tread surface portion 10aa for passing vehicle tires as a step portion from the front to the rear of the loading platform 10a in the vehicle entry direction.
[0032]
Thereby, in this cage 10, since the effective height h2b of the part on which the vehicle is loaded on the loading platform 10a can be set to about 1750 [mm], the effective height is much higher than the conventional effective height h1. As a result, it is possible to easily load not only conventional low-roof vehicles but also mid-roof vehicles and associated heavy vehicles as well as h2a.
[0033]
Further, when such a cage 10 is used in a vertical circulation parking device, the pitch P of each cage 10 in the vertical direction is maintained as in the conventional case (that is, the number of accommodated vehicles is maintained). Since the effective height h2b can be secured even further, not only low-roof vehicles but also mid-roof vehicles and associated heavy vehicles can be easily accommodated, thus widely supporting various vehicles. The number of users can be increased and the operating efficiency can be greatly improved.
[0034]
Now, a manufacturing method for manufacturing a vertical circulation parking apparatus using the cage 10 having such a configuration will be described.
[0035]
First, in an existing vertical circulation parking apparatus as shown in FIG. 3, an empty cage 6 (that is, a cage for a low roof car) on which a vehicle 8 is not loaded is fitted into a pit 9 of the parking structure 1. The cage 6 is removed from the attachment 5 and carried out from the parking structure 1 of the vertical circulation parking device. Next, the cage 10 of the present invention (that is, a cage for a mid-roof vehicle) is carried into the part from which the cage 6 has been removed, and the cage 10 is attached to the attachment 5.
[0036]
In this way, the existing vertical circulation parking apparatus can be applied to various vehicles by a simple operation of replacing the cage 6 for the low roof car in the existing vertical circulation parking apparatus with the cage 10 for the mid roof car. It can be modified to a vertical circulation parking device, and as a result of replacing the minimum necessary parts in this way, waste of resources can be eliminated and the manufacturing cost and time of the vertical circulation parking device can be greatly reduced.
[0037]
Incidentally, such manufacturing (remodeling) work is interrupted in the original operation of the parking device in order to replace the empty cage 6 in which the vehicle 8 is not loaded in the existing vertical circulation parking device with the cage 10 of the present invention sequentially. For example, it is preferably performed at night when the number of vehicles entering the parking device is relatively small.
[0038]
In such a manufacturing operation, the effective heights h2a and h2b of the cage 10 for the mid-roof vehicle are higher than the effective height h1 of the cage 6 for the conventional low-roof vehicle. By scraping the floor surface of the loading / unloading port 7 of the vehicle 8, the positions of the attachment 5 of the endless chain 4 and the cage suspension shaft 10c of the cage 10 can be made to correspond to each other, so that the cage 10 can be easily attached. can do.
[0039]
Further, the effective heights h2a and h2b of the cage 10 are thus arranged so as to be rotatable up and down in the parking structure 1 by an amount that is higher than the effective height h1 of the conventional cage 6. By moving the upper sprocket 2 and the lower sprocket 3 upward in the parking structure 1, the positions of the attachment 5 of the endless chain 4 and the cage suspension shaft 10c of the cage 10 can be made to correspond to each other. The work of attaching the cage 10 to the attachment 5 can be facilitated.
[0040]
Further, in this case, since the position of the tire tread surface portion 10aa on the loading platform 10a of the cage 10 can be matched with the position of the floor surface of the loading / unloading port 7, the loading / unloading of the vehicle 8 with respect to the cage 10 can be maintained smoothly. it can.
[0041]
Further, in this case, the pair of endless chains 4 stretched between the upper sprocket 2 and the lower sprocket 3 in the parking structure 1 are removed and pinched, for example, by one link, so that the total length of these endless chains 4 is shortened. Accordingly, the lower sprocket 3 can be moved (lifted) upward with respect to the upper sprocket 2.
[0042]
For this reason, in such a manufacturing method, the position of the attachment 5 of the endless chain 4 and the cage suspension shaft 10c of the cage 10 can be saved without having to bother to move (up) the parking structure 1 up to the upper sprocket 2. And the attachment work of the cage 10 to the attachment 5 can be facilitated.
[0043]
Further, in this case, since the position of the tire tread surface portion 10aa on the loading platform 10a of the cage 10 can be matched with the position of the floor surface of the loading / unloading port 7, the loading / unloading of the vehicle 8 with respect to the cage 10 can be maintained smoothly. it can.
[0044]
In the above-described embodiment, the case where the upper sprocket 2, the lower sprocket 3 and the endless chain 4 in the parking structure 1 are provided in pairs has been described, but the present invention is not limited to this. In short, if the cage 10 attached to the endless chain 4 via the attachment 5 is rotatably held so that it can circulate in the parking structure 1, these upper sprocket 2, lower sprocket 3 and endless chain The chain 4 may not be provided as a pair.
[0045]
【The invention's effect】
[0052]
As described above , according to the method for manufacturing the mechanical parking device of the present invention , the end sprocket is pulled up to raise the position of the lower sprocket upward in the parking structure without changing the position of the upper sprocket. Since the attachment position of the cage with respect to the chain can be made to correspond to the axial position of the new cage, the work of attaching the new cage to the mechanical parking device can be further facilitated, and the mechanical parking device can be manufactured. Work efficiency can be significantly improved.
