Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cantilever type cubicle. More specifically, the present invention relates to a three-dimensional hangar used as a parking device for automobiles and a warehouse for articles.

[0002]

2. Description of the Related Art As an example of a conventional three-dimensional hangar, there is a three-dimensional parking device described in Japanese Utility Model Publication No. 4-11092. In this multilevel parking apparatus, a pallet for mounting and storing a vehicle is moved up and down between a plurality of storage layers to store and store the vehicle. The pallet adopts a double-supported structure that is supported by the front end and the rear end in the longitudinal direction, so that the rigidity is enhanced.

[0003]

However, in the case of the double-supported structure as described above, it is of course necessary to set up the columns on both the front side and the rear side of the hangar to set the guide rails and the like. The depth of the hangar in this case is the length of the vehicle + the installation space for the columns on the front side + the installation space for the columns on the rear side + a little extra space. Due to this, there are cases where it cannot be installed due to a slight lack of dimensions.

In view of such circumstances, it is an object of the present invention to provide a three-dimensional hangar with a narrow depth dimension that can be installed even in a site with a small depth that cannot be installed by a hangar having a conventional double-support structure.

[0005]

The cantilever type three-dimensional hangar of the present invention is a multi-storey floor consisting of a lowermost layer, an intermediate layer of n steps and an uppermost layer, and each layer has a storage space of m rows in the direction of the interrogation. It is a hangar, and the front side of the hangar is opened, and a horizontal rail for n steps and an elevating rail for m columns are provided on the rear side. At the bottom layer, a horizontal pallet that can only traverse is m-
One unit is arranged, and m-1 units of bidirectional pallet units which can be moved up and down and traversed by being guided by the traverse rail and the elevating rail are arranged in each intermediate layer, and the uppermost layer is guided by the elevating rail. It is characterized by arranging m lifting pallet units that can only be lifted.

Further, in the present invention, the bidirectional pallet unit comprises a traverse carriage and a pallet, and the traverse carriage has a traveling roller for traveling on a transverse rail, a traveling drive device and a transverse guide roller. And a hoisting device for hoisting and hoisting a rope connected to the pallet, and a hoisting device for hoisting and lowering a rope connected to the pallet. It is preferable that a lifting guide roller guided by the lifting rail is provided on the rear end side in the direction, and the pallet is composed of a suspension beam and a pallet, and the suspension beam is projected toward the front side of the hangar. It is fixed to the rear side fixing member of the uppermost layer, and is equipped with a hoisting device that hoists and hoists the ropes connected to the four corners of the pallet. Tsu DOO is preferably provided with a lifting guide rollers which are guided by the elevator rail to the rear end of the longitudinal direction. Further, in the bidirectional pallet unit according to the present invention, when the pallet is lifted to the storage position, the pallet is moved forward from the position immediately before the storage position to the storage position so that the lifting rail and the lifting guide roller are disengaged. It is preferable to provide means for displacing.

Further, in the present invention, the lifting rail is a U-shaped section having two ribs, the lifting guide roller is a slot roller, and is provided on both sides of the rear end side of the pallet. It is preferable that one elevating guide roller on one side of each pallet engages with one of the right and left ribs of one elevating rail to elevate and lower, and one elevating rail guides two adjacent pallets.

[0008]

According to the present invention, in a multi-storey floor m-row hangar, the transverse pallet unit in the lowermost layer and the bidirectional pallet unit in the middle tier are one less than the number m of rows. Any one of the rows can be opened as a hoisting space, and the hoisting space is moved up and down by the hoisting and lowering pallet units in the uppermost layer and the bidirectional pallet unit in the middle layer. Can be made.

Further, in the present invention, the bidirectional pallet unit of the intermediate layer is a cantilever structure suspended from a suspension beam attached to a traverse truck traveling on a traverse rail installed only on the rear surface side, and the uppermost layer. The lifting type pallet unit also has a cantilever structure that is hung from a suspension beam attached to the rear side fixing member. In other words, since no support pillar or the like for supporting the front side of each pallet is required, the depth dimension of the hangar can be shortened by the dimension occupied by the front support pillar or the like. Therefore, the hangar of the present invention can be installed in a place where installation is conventionally impossible, provided that the site has a slightly small depth.

Further, in the case where the deviation mechanism is provided, when the bidirectional pallet unit is traversed, interference between the lifting guide roller of the pallet and the lifting rail can be avoided.
The traverse operation can be performed smoothly, and damage to the guide rollers and the like can be prevented. Also, make the lifting rail a U-shaped section,
When the lifting guide rollers of the adjacent pallets are guided by the left and right ribs of one lifting rail, the number of lifting rails can be reduced, so that the material cost can be reduced and the frontage size of the hangar can be reduced.

[0011]

EXAMPLE Next, an example in which the present invention is applied to a parking device for an automobile will be described. (Overall Configuration) First, the overall configuration will be described with reference to FIGS. FIG. 1 is a conceptual view of a cantilever type multi-storey parking lot, where 1 is the bottom layer, 2 and 3 are the middle layers, and 4 is the top layer. In the illustrated example, the intermediate layer has two layers, but it may have one layer or three or more layers. The number of layers is not particularly limited, but practically 3 to 7 layers are preferable as a whole. Each layer is divided into a plurality (m rows) of storage spaces in the frontage direction. In the illustrated example, there are four rows of a, b, c and d, but they may be three rows or less or five rows or more. The number of rows is not particularly limited, but in reality, it is preferably about 2 to 10 rows.

In the lowermost layer 1, a number of transverse type pallets 5 which is one less than the number of columns (three in the illustrated example) are arranged, and in the middle layers 2 and 3 one less than the number of columns (the illustrated example is shown). Then 3
Two-way type pallet units 6 and 7 are arranged, and the uppermost layer 4 has the same number of elevating and lowering pallet units 8 as the number of rows (four in the illustrated example). Transverse pallet 5
Is a pallet capable of traversing only, the bidirectional pallet units 6 and 7 are pallet units capable of both traversing and lifting, and the lifting pallet unit 8 is a pallet unit capable of only lifting.

FIG. 2 is a front view showing the rear wall of the parking lot, and FIG.
FIG. 3 is a sectional view taken along line III-III in FIG. In the figure, 11
Is a traverse rail, and is composed of a lower rail 12 and an upper guide 13. This traverse rail 11 is provided for two layers in accordance with the number of intermediate layers 2 and 3. Also, 14 is a lifting rail, which is provided for four rows. The elevating rail 14 rises from the floor surface F of the lowermost layer 1 and extends slightly above the upper guide 13 of the uppermost stage. The intersection with the traverse rail 11 is cut out. Reference numeral 15 is a traveling rail installed on the floor surface F of the lowermost layer 1, and a set of two rails extends in the frontage direction.

FIG. 4 is a schematic side view showing a state in which the pallet units 5, 6, 7, 8 are arranged in the above parking device. As shown in the figure, in the first layer 1, the transverse pallet 5 is used.
The bidirectional pallet units 6 and 7 are arranged on the second layer 2 and the third layer 3, and the elevating type pallet unit 8 is arranged on the fourth layer 4. The bidirectional pallet units 6 and 7 each have a suspension beam 18 for suspending the traverse carriage 16 and the pallet 17, and the lifting pallet unit 8 is composed of the suspension beam 18 and the pallet 17. There is.

Next, the configuration of each part will be described in detail. (Transverse pallet 5) FIG. 5 is a side view of the transverse pallet 5, and FIG. 6 is a perspective view thereof. As shown in FIGS. 5 and 6, a frame 22 is formed on three sides of a mounting surface 21 on which a vehicle is placed, and a slope 23 is formed on the remaining side to facilitate the entry of the vehicle. Traveling rollers 24 and 25 are respectively supported at four corners of the frame body 22, and a motor 26 with a speed reducer, which is a traveling drive device, is connected to the pair of traveling rollers 24. The traverse type pallet 5 travels on the traveling rail 15 by rotating the motor 26 with a reducer in the forward and reverse directions. It should be noted that this traveling mechanism mechanism is an example, and any traveling mechanism that can be traversed can be adopted.

(Bidirectional pallet unit 6, 7) FIG.
Is a side view of the bidirectional pallet unit 6, and FIG. 8 is a perspective view of the bidirectional pallet unit 6 as viewed from the rear surface side.
In FIGS. 7 to 8, reference numeral 16 denotes a transverse carriage configured in a quadrangular frame. A traveling roller 32 is pivotally supported at both ends of the lower frame 31 on the rear surface side thereof, and lower guides are provided at both ends of the lower surface of the lower frame 31. A roller 33 and an upper guide roller 35 are pivotally supported on both ends of the upper frame 34 on the rear surface side.

Details of the rollers 32, 33 and 35 and the traverse rail 11 that supports them will be described with reference to the enlarged view of FIG. The lower rails 12 that make up the traverse rails 11 are square rod-shaped, and the upper guides 13 are U-shaped steel.
12 is installed on the upper guide 13 of the traverse rail 11 on the lower layer side. The traveling roller 32 rides on the lower rail 12, the upper guide roller 35 rolls in contact with the inner peripheral wall of the upper guide 13 of the layer, and the lower guide roller 33 contacts the front side of the upper guide 13 of the lower layer. Roll around. As a result, the traverse carriage 16 traverses in a cantilevered state.

As the traveling mechanism of the transverse carriage 16, any mechanism can be adopted without particular limitation.
The traveling mechanisms of 10 to 13 can be exemplified.

The traveling mechanism shown in FIG. 10 has a roller chain 41.
Is extended above the lower rail 12 and fixed at both ends, and the roller chain 41 is wound around the drive chain wheel 42 and the driven chain wheel 43 attached to each traverse carriage 16 in an S-shape. The chain wheel 42 is normally and reversely rotated to cause the traverse carriage 16 to traverse. As a drive device for the drive chain wheel 42, for example, as shown in FIG. 11, a device in which a speed reducer 44 and a motor 45 with a brake are connected to the chain wheel 42 can be adopted. Further, in the above configuration, a wire rope may be used in place of the roller chain 41. In this case, a V-groove type drive wheel and a U-shaped groove drive wheel may be used.

In the traveling mechanism shown in FIG. 12, a roller chain 41 is wound around two traveling rollers 32 pivotally supported by each traverse carriage 16, and a drive wheel 42 and a driven wheel 43 form a roller chain.
The traveling roller 32 is rotatably driven by winding around 41 and moving along the path. Also in this example, a wire rope can be used instead of the roller chain 41. Figure
In the traveling mechanism shown in 13, a large number of rolling rollers 46 are installed along the traveling direction, and the rolling rollers 46 are sequentially rotated,
The traverse carriage 16 placed on the upper surface is traversed.

Next, the structure of the suspension beam 18 will be described.
As shown in FIGS. 7 to 8, a suspension beam 18 projects from the upper end of the transverse carriage 16 toward the front side of the parking device, and the suspension beam 18 is supported by an appropriate reinforcing frame 19.
A hoisting device 50 is installed at the base end of the suspension beam 18. The hoisting device 50 includes a motor 51 with a reducer and a pair of hoisting drums 52 connected to the motor 51. The hoisting drums 52 wind a rope 56 on the front end side and a rope 57 on the rear end side of the pallet 17. It is supposed to be taken. Reference numeral 49 is a guide sheave that is axially supported at the tip of the hanging beam 18.

The hoisting drum 52, as shown in FIG.
Large diameter drum 53 and small diameter drum 54
The rope 56 on the front end side of the pallet 17 is wound around 53, and the rope 57 on the rear end side around the small diameter drum 54. This is because the rope 57 on the rear end side is stretched almost vertically as shown in FIG. 7, but the rope 56 on the front end side is stretched diagonally, and the rope lengths are different. This is to keep the side ropes 56 extra horizontal for the winding pallet 17. The mounting surface 58 and the slope 59 of the pallet 17 are configured substantially the same as the transverse pallet 5.

Next, an elevating guide mechanism for the pallet 17 will be described. 7 to 8, 60 is a guide roller mounting plate, which is mounted on both sides of the pallet 17 at the rear end side.
On the outer surface of this guide roller mounting plate 60, a lifting guide roller
61 and 62 are vertically supported. The details will be described with reference to FIGS. 15 to 16. Reference numeral 14 is a lifting rail, which is vertically mounted by a column 9. The elevating rail 14 is a U-shaped member having two ribs in cross section, and the elevating guide rollers 61, 62 are grooved rollers. The respective elevating guide rollers 61, 62 of the adjacent pallets 17 are individually engaged with and guided by the left and right ribs of the elevating rail 14.

Therefore, when the ropes 56 and 57 are hoisted and hoisted down by the hoisting device 50, the pallet 17 moves up and down along the elevating rails 14. Further, since the adjacent pallets 17 are guided by one lifting rail 14, there is an advantage that the number of lifting rails 14 can be small. In this case, it is preferable that the ropes 56 and 57 suspended from the suspension beam 18 be slightly inclined so that a component force for pressing the pallet 17 against the lifting rail 14 side is generated because the guide operation becomes reliable.

As shown in FIGS. 2 and 3, the elevating rail 14 is notched at the intersection with the traverse rail 11, but since the elevating guide rollers 61, 62 are vertically separated from each other, one guide roller 61 ( Even when 62) is floating at the intersection, since the other guide roller 62 (61) is in contact with the elevating rail 14, the elevating operation is smoothly guided. Therefore, when the ropes 56 and 57 are hoisted down in the directions U and D by the hoisting device 50 as shown in FIG. 7, the pallet 17 can be moved up and down as shown by arrows U and D.

As described above, since the elevating guide rollers 61 and 62 are fitted on the elevating rail 14 during the elevating operation, the guide rollers 61 and 62 and the rail interfere with each other and traverse when the traverse is continued. Therefore, a displacement mechanism for disengaging the lifting guide rollers 61, 62 and the rail 14 during a traverse operation is provided.

Next, the displacement mechanism will be described with reference to FIGS.
It will be explained based on 17-18. Deflection guides are provided at the bases on the front side of the left and right vertical frames 36 of the transverse carriage 16 shown in FIG.
63 is installed. As shown in FIGS. 9 and 17, the deflection guide 63 is a guide plate whose upper portion inclines forward as seen in a side view and whose cross-sectional shape is U-shaped as shown in FIG. On the other hand, the eccentric guide roller 64 is axially mounted inside the pallet mounting plate 60 of the pallet 17. When the pallet 17 is hoisted by the hoisting device 50 on the suspension beam 18, as shown in FIG. 7, when the pallet 17 is located below the traverse vehicle 16, the pallet 17 moves up and down (arrow U). , D
However, when the pallet 17 is lifted (in the direction of arrow U) as shown in FIG. 17 and the displacement guide roller 64 is guided by the displacement guide 63 attached to the transverse carriage 16, the pallet 17 is moved to the direction shown in FIG.
Deviate forward as indicated by arrow F at ~ 18. Then, the lift guide rollers 61, 62 move away from the lift rail 14,
Even when it is moved laterally (in the direction of arrow T in FIG. 18), the lifting rail 14 and the lifting guide rollers 61 and 62 do not interfere with each other.

In the lower part of FIG. 19, another bidirectional pallet unit 7 is shown. The directional pallet unit 7 has the same structure as the bidirectional pallet unit 6 described above, and therefore, the reference numerals of the main parts are given in the drawings and the description thereof is omitted. The bidirectional pallet unit 7 in the figure is in a state in which the pallet 17 is raised to the upper limit, that is, the lower end portion of the transverse carriage 16 and is slightly displaced forward by the displacement mechanism.

(Elevating Pallet Unit 8) A side view of the elevating pallet unit 8 is shown in the upper part of FIG. The elevating pallet unit 8 does not traverse only by the elevating operation, and therefore has the same structure as the bidirectional pallet unit 6 except that it does not have a mechanism necessary for traversing. That is,
The traveling device 40 as shown in FIG. 8 and the displacement mechanism (displacement guide 63 and displacement guide roller 64) shown in FIGS.
The suspension beam 18 is fixed to the upper end of the column 9. Therefore, the pallet 17 can be moved up and down by driving the hoisting device 50.

(Incoming / outgoing operation) Next, the inbound / outgoing operation of the above embodiment will be described. For example, if each pallet is in the state shown in FIG. 20 and the lowermost pallet unit 8d of the uppermost layer is vacant as a hoisting space, the pallet of the hoisting pallet unit 8d is lowered and raised to move the vehicle in and out. Can be made. Further, the lowermost transverse pallets 5a, 5b, 5c can also be used for loading and unloading vehicles at the same positions. However, the other pallet units 8b and the like cannot be lowered as they are because the lower pallet units 7b, 6b, 5b interfere with them. Therefore, as shown in FIG. 21, the bidirectional pallet units 7b, 7c, 6b, 6c and the traverse pallets 5b, 5c are moved to the right to create a hoisting space, on which the pallet of the hoisting pallet unit 8b is lowered. Let In this way, the car can be stored in all the pallets in four rows and four columns and can be freely loaded and unloaded.

(Advantages of this Embodiment) In the above embodiment, all the pallet units (the bidirectional pallet units 6 and 7 and the lifting pallet unit 8) except the lowermost transverse pallet 5 are cantilevered. As the basic structure of the parking lot, it is sufficient to erect the column 9 only on the rear surface side of the parking lot and attach the traverse rails 11 and the elevating rails 14, and it is not necessary to erect the column on the front side of the pallet. Therefore, the depth of the parking lot can be reduced, and even in a narrow site that cannot be installed in a double-sided parking lot,
The present invention can be installed. In addition, the material cost can be reduced by about 30% compared to the double-sided type by omitting the front columns, lifting rails, and traverse rails. The required power for raising and lowering each pallet unit, the safety during traveling, and the durability of the device are the same as the conventional parking device. In the above embodiment, the elevating rail 14 is cut out at the intersection of the traverse rail 11 and the elevating rail 14, and four elevating guide rollers are used for each pallet unit. In this case, in the bidirectional pallet unit, the traverse carriage 16 requires two traveling rollers 32 and two lower guide rollers.
The number of the upper guide rollers is 2, and the total number of the upper guide rollers is 10, but as will be described later, it is possible to reduce the number as compared with the case where the transverse rail is notched, and the cost can be reduced.

(Other Embodiments) In the parking device of the present invention, as described above, at the intersection of the elevating rail 14 and the traverse rail 11,
The elevating rail may not be cut out, and the transverse rail 11 may be cut out. In this case, in the bidirectional pallet unit,
At each corner of the traverse carriage 16, two traveling rollers 32 are arranged in tandem at each corner, and a total of four traveling rollers 32 are provided.
This requires four upper guide rollers 35 as well. On the other hand, even if the number of the elevating guide rollers of the pallet 17 can be reduced to one at each corner and the total can be reduced to two, the total is 14, and the number of rollers is increased. However, since there is no problem in terms of functionality, the present invention includes such a type.

Also, the three-dimensional storage of the present invention can be applied to a warehouse. In this case, if the pallet for loading automobiles is understood as a pallet for storing articles, the structure of the above-mentioned multilevel parking lot can be understood as it is as a multilevel warehouse.

[0034]

According to the present invention, it is possible to provide a low-cost three-dimensional hangar which has a small depth dimension and can be installed in a narrow site where the conventional double-holding three-dimensional hangar cannot be installed, and which has a small number of materials and parts.
