Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical three-dimensional parking system for passenger cars, and more specifically, a vertical circulation system in which vehicles are mounted in a plurality of cages and circulates in a ferris wheel type by a link chain. It relates to a parking device.

[0002]

2. Description of the Related Art Generally, an arm for suspending and supporting a cage of a vertical circulation type parking apparatus is mounted on the outside of a stretched endless link chain 101 as shown in FIG. (See FIG. 5a) or at intervals of 2 pitches (see FIG. 5b) or more, link plate connecting pins 10 are formed.
5, arm plates 107 are attached to both ends of the plate 5, and triangular arms 111 formed by connecting the other ends 109 of the arm plates 107 to each other are provided in a protruding manner. Further, in order to smoothly vertically circulate the endless link chain 101 and the vehicle-mounted cage 113, a guide roller 115 is usually attached to the link plate connecting pin 105 attached to one end of the arm plate 107. 115 is guided by a guide rail 117 arranged along the stretched endless link chain 101.

In the vertical circulation type parking apparatus, a plurality of cages 113 and a vehicle are usually suspended and supported on an endless link chain 101 via an arm plate 107. No safety measures are taken to prevent the cage 113 and all of the vehicle from dropping when disconnected.

[0004]

Since this conventional arm plate is attached to both ends of the link plate connecting pin, there are two link plates and the arm plate, and the end of the link plate connecting pin is three on one side. The plates are overlapped with each other, and six plates are overlapped on both sides, and a guide roller is attached to the outer side of one of them, so that the link plate connecting pin needs to be significantly longer than those of the other parts ( See Figure 5c).

If a guide roller is attached to a link plate connecting pin to which an arm plate is attached, and a guide rail for guiding the guide roller is directly attached to a main pillar which is a frame body of a vertical circulation type parking apparatus, the left and right sides are The spacing between the main columns becomes the same as the spacing between the two left and right endless link chains stretched by the upper and lower sprocket wheels, and becomes unstable. Further, if the main pillars are widened, it is necessary to additionally provide columns for attaching the guide rails.

Further, the endless link chain is designed with a safety factor which is several times the maximum load expected, but if the chain is cut due to metal fatigue or disconnection of the connecting pin, countermeasures are taken. It is not difficult to imagine that all the cages and the vehicles stored in the car will fall, resulting in a major accident.

The present invention reduces the weight and simplification of the structure of the arm plate and the link plate, integrates the guide rail and the main pillar with a stable structure, and secures the multi-level parking even if the chain is accidentally cut. The purpose is to provide a device.

[0008]

In order to achieve the above object, the multi-dimensional parking apparatus of the present invention has a pair of sprocket wheels vertically spaced with an endless link chain stretched between them. In a three-dimensional parking apparatus in which a plurality of cages for mounting on a vehicle are suspended and circulated through an endless link chain via an arm, an arm that suspends and supports the cage is one of links of the endless link chain. An integrated type that doubles as a part. In addition, a guide roller for guiding the movement of the arm is provided at an intermediate position between the arm base portion which is the joint portion of the arm and the endless link chain and the arm tip which is the joint portion of the arm and the cage. Then, the guide rail which is a vertical track of the guide roller is integrally formed with the main pillar of the apparatus frame. Furthermore, all of the adjacent ones of these arms are connected by a wire rope appropriately provided with a slack within a range in which vertical circulation drive of the endless link chain is smoothly performed.

[0009]

[Operation] Since the arm that suspends and supports the cage is also an integrated type that also serves as a part of the link of the endless link chain, the structure of the arm portion of the endless link chain is simplified and the weight is reduced. The link plate connecting pins can have the same length.

Further, since the guide roller for guiding the movement of the link is provided at an intermediate position between the arm base portion which is the connecting portion of the arm and the endless link chain and the arm tip which is the connecting portion of the arm and the cage, it is vertical. The guide rail position of the track is outside the pitch line of the endless link chain, and the guide rail interval placed on the left and right expands.Even if the main column of the device frame is installed at this position, the stability of the device installation is impaired. Since there is no guide rail, it is possible to support the guide rail on the main pillar. Therefore, unlike the case where the guide is provided on the pitch line of the endless link chain, it is not necessary to separately provide a support column that supports the guide.

Further, with wire ropes appropriately provided with a slack within a range in which vertical circulation drive of the endless link chain is smoothly performed, all the adjacent arm portions constituting the endless link chain are connected to each other. Because I did
Even if an unexpected situation occurs in which the components of the endless link chain are broken, it is possible to avoid the damage that all the vehicles mounted in the cage fall to the ground and are damaged due to the splitting of the chain.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the whole of a multi-level parking apparatus according to the present invention, and a front portion of a frame of the entire apparatus is omitted for easy understanding. FIG. 2 is a sectional view taken along the line II-II in FIG.

In FIG. 1, reference numerals 11, ..., 11 denote cages for accommodating vehicles, one by one, respectively, and arm 1, respectively.
3, ..., 13 are suspended and supported in a freely suspended state. The arms 13, ..., 13 have connecting pins 15,
, 15 are connected to form a link plate of the endless link chain 17. Also, this arm 13,
, 13 is a guide roller 23 for guiding the movement of the arm to an intermediate position between an arm base 19 which is a connecting portion of the arm 13 and the endless link chain 17 and an arm tip 21 which is a connecting portion of the arm and the cage. , 23 are provided. The guide rollers 23, ..., 23 are connected to the guide rails 25, 2
Guided by 5, the cage 11 is regulated so as to move along the vertical track without the endless link chain 17 in the vertically moving state being bent.

The main pillars 29, 29 of the apparatus frame 27 are provided along the guide rails 25, 25, and I of FIG.
As shown in the cross-sectional view taken along the line II-III, each main rail 29 supports each guide rail 25. Main pillar 29,2
Since 9 is outside the vertical pitch line 31 formed by the endless link chain 17, the installation stability of the entire apparatus is improved.

33, ..., 33 are wire ropes,
The endless link chain 17 is appropriately loosened so that the vertical circulation drive can be smoothly performed, and the endless link chain 17 is fixed to the wire rope mounting seats 35 fixed to the adjacent arms 13 and 13, and all the spaces between them are fixed. It is connected. Therefore, in the event of an unexpected situation in which one of the constituent members of the endless link chain 17 breaks, the wire rope 33 between the arms 13 and 13 will not move even if the chain is broken.
Since the separation between the cables 3, 13 is prevented, the endless link chain 17 still maintains a continuous endless state, and the cage 11,
It is possible to avoid the situation in which all the vehicles mounted on the 11 are dropped to the ground and damaged.

Connecting pin 1 of the endless link chain 17
5, 15 move the endless link chain 17 as the upper sprocket wheel 37 rotates while engaging with the sprocket groove 39 provided on the outer periphery of the upper sprocket wheel 37 at the upper side. The endless link chain 17 is guided below along a fixed guide 41 having a substantially semi-circular shape.

As shown in FIG. 2, the same mechanism as described above including the arm 13 for suspending and supporting the cage 11 and the endless link chain 17 is symmetrically arranged in front of and behind the apparatus with the cage 11 in between. The respective endless link chains 17 arranged before and after this are linked by a main shaft 43 that drives the opposing upper sprocket wheels 37, 37 in a chain. The main shaft 43 rotates the drive force of the motor 49 to the drive chains 47 and 47 wound around the drive sprocket wheels 45 and 45 fixed coaxially with the upper sprocket wheels 37 and 37, respectively. Communicate through. Numerals 53 and 53 are idle wheels that clamp the drive chain 47 to adjust the tension and determine the orbit of the drive chain 47.

When the vehicle is loaded or unloaded, the motor 49 is driven, and the upper sprocket wheel 37 is rotated by the drive chain 47 through the speed reducer 51, and the endless link chain 17 is circulated to move the cage. 11 is moved to the position S shown in FIG. In this embodiment, a motor is used as the driving force, but it is possible to use another driving source such as an engine.

Next, the relationship between the arm 13, the guide roller 23, the guide rail 25, etc. when the endless link chain 17 is circulated and moved will be described. For example, the cage 11 located at the lowermost end in the figure and the guide roller 23 of the arm 13 supporting the total weight of the mounted vehicle are guided by the fixed guide 41 according to the movement of the endless link chain 17,
It is introduced into the guide rail 25 through the opening 55 that moves from the arcuate orbit to the vertical straight orbit (see FIG. 4). In the guide rail 25, the rotation moment generated in the arm 13 due to the weight of the cage 11 and the mounted vehicle is supported by the side surface of the guide rail 25 via the guide roller 23, and the endless link chain 17 has only the vertical component as tension. To work. Further, when the guide roller 23 separates from the guide rail 25 in the upper part of the guide rail 25, the arm 13 forms the link plate of the endless link chain 17, so that the action of gravity on the cage 11 is caused by the arm 13. All of the upper sprocket wheels 37 will bear through the connecting pins 15.

[0020]

According to the vertical circulation type parking apparatus of the present invention,
The arm that suspends and supports the cage is an integral type that also functions as a part of the link of the endless link chain, and the guide roller that guides the movement of the link is composed of the arm base and the arm that is the joint between the arm and the endless link chain. Since it is provided at an intermediate position with the tip of the arm that is the connecting part of the cage, the structure of the arm part of the endless link chain is simplified and lightened, and all the connecting pins have the same length. Therefore, it is possible to improve economy in terms of production and maintenance.

Further, since the guide roller for guiding the movement of the link is located outside the pitch line of the endless link chain, the space between the vertical guide rails arranged on the left and right is widened, and the stability of installation of the apparatus is impaired. It is possible to support the guide rail on the main pillar without any need.

Furthermore, since the adjacent arms are all connected to each other by the wire rope to which the slack in the range where the vertical circulation drive of the endless link chain is smoothly performed is given, the constituent members of the endless link chain are formed. Even if an unforeseen situation occurs, such as fatigue of the robot or breakage of the connecting pin, the wire rope keeps the connection between the arms, and all the vehicles mounted in the cage fall to the ground and are damaged. The situation of doing can be avoided.
