Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a multi-tiered parking device, and more particularly to a multi-tiered parking device in which the upper pallet is stacked on the lower pallet in front of the loading / unloading port when the upper pallet is loaded and unloaded.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there has been known a multi-stage parking apparatus in which a plurality of pallets are arranged in the vertical direction at predetermined intervals and a vehicle is stored in each pallet.

As such a multi-stage parking device, for example, as disclosed in Japanese Patent Laid-Open No. 1-256671, four guide rods extending in the up-and-down direction are provided at four corners of the upper and lower pallets, respectively. A multi-stage parking system has been proposed in which the above-mentioned upper and lower pallets are held at a predetermined interval in the vertical direction when the vehicle is stored, and the upper pallet is stacked on the lower pallet in front of the entrance / exit when entering and exiting. There is.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned proposed multi-tiered parking system, when entering and exiting each pallet, there is a step between each pallet and the ground to improve the entry / exitability of the vehicle. The slopes of the upper pallet are stacked on the lower pallet, and the front and rear dimensions of each pallet are different so that the slopes of both pallets are continuous. Therefore, it is necessary to prepare a plurality of pallets having different shapes, which increases the manufacturing cost (see FIG. 3 of Japanese Patent Laid-Open No. 1-256671).

Therefore, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2-91361, the ground below each pallet is recessed to form a pit, and the pallets at the lowermost stage and the middle stage are formed in the pit. By raising and lowering by parallel links, each pallet is set at the same height level as the vehicle entry surface in front of the entry / exit gate when entering and exiting so that there is no step difference between each pallet and the ground, and the vehicle entry / exitability is improved. This eliminates the need to form a front-down slope on the front end of each pallet, and also eliminates the difference in the front-rear dimension of each pallet due to this slope, and allows the same shape of pellets to be formed. A multi-tiered parking system has been proposed for use in each storage stage.

However, in this latter multi-tiered parking system, although the pallets at the bottom and middle tiers can be brought to the same height level as the vehicle entry surface in front of the entrance / exit entrance, these pallets are lifted by parallel links. As a result, the lifting stroke of the pallet is naturally limited, and it is not suitable for storing a large number of vehicles, for example, four or five steps.

Further, in this multistage parking apparatus, in order to allow each pallet to move only in the vertical direction, a column is provided in the pit, and each pallet is guided up and down on the column, and the lower end of the parallel link is Since a roller is attached to the bottom of the parallel link to support the lower end of the parallel link so that the bottom of the pit can move laterally, the pallet support structure becomes complicated and the manufacturing cost increases.

The present invention has been made in view of the above point, and its purpose is to replace a parallel link as a link for providing a pit and raising and lowering a pallet as in the latter proposal example described above. By adopting links, many pallets of the same shape can be used to store many vehicles without impeding the entry capacity, and in combination with a simple pallet support structure, the manufacturing cost can be reduced. .

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is equipped with a plurality of pallets for mounting a vehicle and storing them in a multi-tiered manner, and the upper and lower pallets adjacent to each other are vertically spaced apart when the vehicle is in a retracted state. The multi-stage parking system was designed so that it can be stored and stored on the pallet in front of the warehousing entrance / exit when the garage exits and exits.

That is, the solution means of the present invention is to provide a pit formed by recessing the ground below each of the pallets. Further, an elevating means is provided in the pit. The elevating means is an X-link for raising and lowering the vehicle entry portion by a telescopic operation, one end of which is connected to the vehicle entry portion side and the other end of which is connected to the pit bottom portion side, which constitutes the lowermost storage portion. It is equipped with and. When the vehicle is loaded into the pallets and the vehicle loading section, the lifting means is moved up and down so that the upper surfaces of the pallets and the vehicle loading section are at the same level as the vehicle loading surface in front of the loading / unloading entrance. It is characterized in that it is configured to.

[0011]

[Action]

 With the above configuration, in the solution means of the present invention, when the lower pallet descends in front of the loading / unloading port, the upper pallet subsequently descends and overlaps with the lower pallet. The vehicle is parked.

At this time, the X-link contracts due to the descending operation of the elevating means, and the upper surface of the upper pallet becomes at the same height level as the vehicle loading surface in front of the loading / unloading port. The other pallets are located in the pit below the vehicle entry surface.

Then, when the upper pallet is raised, the upper pallet is separated from the lower pallet below it, both pallets are held at a predetermined interval in the vertical direction, and the vehicle is loaded into the lower pallet. .

At this time, the X-link is extended by the ascending operation of the elevating means, and the upper surface of the lower pallet becomes at the same level as the vehicle entry surface in front of the entrance / exit port.

After that, similarly, the upper surface of the vehicle loading portion that constitutes each lower pallet and the lowermost storage portion is positioned at the same height level as the vehicle loading surface in front of the loading / unloading entrance, and the vehicles are loaded. It

On the other hand, in the case of warehousing, the reverse operation of the above causes the upper surface of each pallet and the vehicle entry portion to be positioned at the same height level as the vehicle entry surface in front of the entry / exit opening and exiting the vehicle.

From this, when entering and exiting each pallet and vehicle entry section, there is no step between the pallet and vehicle entry section and the ground, and the vehicle can get on and off smoothly and the vehicle can get on and off easily. Become. Therefore, in order to improve the ease of getting on and off the vehicle, a front-down slope is formed at the front end of each pallet, and the front-rear dimension of each pallet is set so that each slope is continuous when the pallets are stacked. The pallets do not have to be different, and therefore pallets of the same shape can be used without having to use a plurality of pallets having different shapes depending on the number of storage stages, and the manufacturing cost is low.

Further, since each pallet and the vehicle loading section are moved up and down by the expansion and contraction operation of the X-link, when moving up and down, they move only in the vertical direction and do not move in the horizontal direction. It is not necessary to guide each pallet to the pillars provided in the pit, or to attach a roller to the lower end of the horizontal link to support the lower end of the parallel link so that it can move laterally at the bottom of the pit. Since it is unnecessary, it has a simple structure and can be manufactured at low cost.

Further, since the ascending / descending operation is performed by the X-link, the ascending / descending stroke becomes significantly longer than that in the case of the parallel link, and is sufficiently applied even when a large number of vehicles are stored, for example, in four or five steps. It

Guide rods 11 extending in the up-down direction are respectively stretched around the four corners of the upper and middle pallets P1 and P2 which are vertically adjacent to each other, and the upper ends of the guide rods 11 are the four corners of the upper pallet P1. The guide rods 11 are slidably fitted in the stoppers 12 so as not to come off, and the lower ends of the guide rods 11 are swingably connected to the four corners of the middle pallet P2 by shafts 13. The upper and middle pallets P1 and P2 are guided by the guide rods 11 so as to be vertically movable toward and away from each other, and the upper pallets P1 are in contact with the stoppers 12 while the upper pallets P1 and P2 are in contact with each other. The pallet P1 is held at a predetermined distance from the middle pallet P2.

A pit 14 is formed below the upper and middle pallets P1 and P2 by recessing the ground 1, and a feature of the present invention is that the pit 14 is a lifting device as a lifting means. 15 are installed. The lifting device 15 is provided with a lower pallet P3 as a vehicle loading section that constitutes a lowermost storage section, and the lower pallet P3 is supported by a frame 16 from below. The lower pallet P3 is also formed in the same shape as the upper and middle pallets P1 and P2. Although not shown, the lower pallet P3 and the middle pallet P2 are also guided up and down by four guide rods in the same manner as the upper and middle pallets P1 and P2 so as not to be displaced.

At the four corners of the frame 16, a pair of left and right X-links 18 and 18 (in the front-and-rear direction of the paper in each figure) formed by pivotally supporting two links 17 and 17 so as to intersect in an X shape. One end (upper end) of the link 17 is connected, and the other end (lower end) of each link 17 of the X links 18, 18 is connected to the base 19 on the bottom surface of the pit 14.

More specifically, the upper end of the one link 17 is pivotally supported by the frame 16, and a roller 20 is attached to the lower end thereof, and the roller 20 is transferred to a guide member 21 provided on the base 19. It is attached so that it moves sideways while moving. On the other hand, a roller 20 is also attached to the upper end of the other link 17, and the roller 20 is attached to a guide member 21 provided on the frame 16 so as to move laterally while rolling, and the lower end is a base. It is pivotally supported at 19.

An elevating cylinder 22 having a piston rod 22a extending obliquely upward is swingably installed on the base 19, and the tip of the piston rod 22a of the elevating cylinder 22 is located at the middle of the one link 17. It is connected.

As shown in FIG. 1, when the upper pallet P1 is loaded into the vehicle, the three upper tiers, the middle tier and the lower pallets P1, P2, P3 are stacked on the frame 16 of the lifting device 15, and the upper pallet P1 is placed on the upper pallet P1. The X-links 18 are contracted synchronously by the contraction operation of the elevating cylinder 22 so that the upper surface of the pallet P1 is at the same level as the vehicle entrance surface (ground 1) in front of the entrance / exit.

Further, as shown in FIG. 2, when the vehicle is loaded into the middle pallet P2, only the upper pallet P1 is raised to maintain a predetermined space (storage space) between the pallet P2 and the middle pallet P2. With the pallets P2, P3 stacked on the frame 16 of the lifting device 15, the lifting cylinder is adjusted so that the upper surface of the middle pallet P2 is at the same level as the vehicle entrance surface (ground surface 1) in front of the loading / unloading entrance. By the extension operation of 22, the X links 18 are extended in synchronization.

Further, as shown in FIG. 3, when the vehicle is loaded into the lower pallet P3, the upper and middle pallets P1 and P2 are both raised to maintain a predetermined space (storage space) between the lower pallet P3 and the lower pallet P3. In this state, the X-links 18 are synchronously extended by the extension operation of the elevating cylinder 22 so that the upper surface of the lower pallet P3 is at the same level as the vehicle entry surface (ground 1) in front of the loading / unloading entrance. It is done like this. As a result, a total of three vehicles C, C, C are stored.

Next, an example of the procedure for loading and unloading the vehicle C into and from the multistage parking apparatus A configured as described above will be described.

<In case of warehousing> First, the winch 7 is rewound by, for example, normal rotation drive of the lifting motor to rewind each wire rope 9 in synchronism, and while the middle pallet P2 is being guided by each guide rod, the frame is moved. After being lowered onto the lower pallet P3 supported by 16, the upper pallet P1 is lowered while being guided by the respective guide rods 11 by the forward rotation drive of the further elevating motor, and then superimposed on the above middle pallet P2. As shown in FIG. 1, the X-links 18, 18 are synchronously contracted by the contraction operation of the lifting cylinder 22, so that the upper surface of the upper pallet P1 is at the same level as the vehicle entrance surface (ground 1) in front of the entrance / exit opening. To In this state, the vehicle C is loaded onto the upper pallet P1 from the loading / unloading port.

Then, the winch 7 is hoisted by, for example, the reverse rotation drive of the lifting motor to hoist each wire rope 9 in a synchronous manner, and the upper pallet P 1 is guided by the respective guide rods 11 above the middle pallet P 2. To raise. As a result, the upper pallet P1 hits the stoppers 12 at the upper ends of the respective guide rods 11, a predetermined space is provided between the upper pallet P1 and the middle pallet P2, and a storage space for securing the vehicle C above the middle pallet P2 is secured. . Thereafter, as shown in FIG. 2, the X-links 18, 18 are synchronously extended by the extension operation of the elevating cylinder 22 so that the upper surface of the middle pallet P2 is the same as the vehicle entry surface (ground 1) in front of the loading / unloading port. Set to height level. In this state, the vehicle C is loaded onto the middle pallet P2 from the loading / unloading port.

After that, the upper and middle pallets P 1 and P 2 are raised while maintaining a predetermined interval by further driving the lifting motor in the reverse direction. As a result, a predetermined space is provided between the middle pallet P2 and the lower pallet P3, and a storage space in which the vehicle C can ride is secured above the lower pallet P3. After that, as shown in FIG. 3, the X-links 18, 18 are synchronously further extended by the extension operation of the ascending / descending cylinder 22, and the upper surface of the lower pallet P3 serves as the vehicle entry surface (ground 1) in front of the entrance / exit opening. Use the same height level. In this state, the vehicle C is loaded onto the lower pallet P3 from the loading / unloading port, and the vehicles C, C, C are stored in the upper and lower three tiers.

<Detachment> First, the vehicle C is delivered from the lower pallet P3 at the same level as the vehicle entry surface (ground 1) in front of the entry / exit opening.

Next, the winch 7 is rewound by, for example, normal rotation drive of an elevating motor to rewind each wire rope 9 in synchronism, and is lowered onto the lower pallet P3 while guiding the middle pallet P2 to each guide rod. After that, the X-links 18 are synchronously contracted by the contracting operation of the elevating cylinder 22 to bring the upper surface of the middle pallet P2 to the same level as the vehicle entrance surface (ground 1) in front of the entrance / exit opening. In this state, the vehicle C is unloaded from the middle pallet P2.

After that, by further driving the elevator motor in the normal direction, the upper pallet P1 is lowered while being guided by the respective guide rods 11 and stacked on the middle pallet P2, and then the above-mentioned elevator cylinder 22 is contracted to move the X-link. 18 and 18 are further contracted synchronously to bring the upper surface of the upper pallet P1 to the same height level as the vehicle entry surface (ground 1) in front of the loading / unloading entrance. In this state, the vehicle C is unloaded from the upper pallet P1.

As described above, in this embodiment, there is no step between the upper, middle, and lower pallets P1, P2, P3, which are to be loaded and unloaded, and the vehicle entry surface (ground 1). Therefore, the vehicle C can be smoothly loaded and unloaded, and the riding property of the vehicle C can be improved. Therefore, in order to improve the entry / exitability of the vehicle C, a front-down slope is formed at the front ends of the upper, middle, and lower pallets P1, P2, P3, or each pallet P1, P2, P3 is piled up in a stacked state. The pallets P1, P2, and P3 do not have to have different front-to-back dimensions so that the slopes are continuous, which allows them to have the same shape without preparing multiple pallets of different shapes depending on the number of storage stages. A pallet is sufficient, and the production cost can be reduced.

Further, in the above embodiment, since each pallet P1, P2, P3 is moved vertically only by the expansion / contraction operation of the X-link 18 and is moved up and down so as not to move horizontally, the case of a parallel link is used. It is not necessary to guide each pallet to the pillars provided in the pit, or to attach a roller to the lower end of the parallel link to support the lower end of the parallel link so that it can move laterally at the bottom of the pit. It can be manufactured at low cost with a simple structure by eliminating the supporting member.

Further, in the above-described embodiment, since each pallet P1, P2, P3 is moved up and down by the X link 18, the lifting stroke can be made significantly longer than that in the case of the parallel link, and the vehicle is, for example, 4 times. It has an advantage that it can be sufficiently applied to the case of storing a large number of columns or 5 stages.

[Effect of device]

 As described above, according to the present invention, the elevating means having the X-link is provided in the pit, and a plurality of pallets for storing the vehicle in the upper and lower multi-stages and a vehicle loading section for forming the lowermost storage section are provided. When the vehicle is loaded, the pallets and the vehicle loading surface are designed to move up and down so that the upper surface of each pallet and the vehicle loading area is at the same level as the vehicle loading surface in front of the loading / unloading entrance. Since there is no step between the vehicle and the vehicle, the ease of getting on and off the vehicle can be improved. Therefore, considering the ease of getting on and off, it is not necessary to form a slope at the tip of each pallet, and the vehicles can be stored in multiple stages with pallets of the same shape. In addition, the functional characteristics of the X-link make it possible to make a large pallet lifting stroke, store a large number of vehicles, and eliminate the need for supporting members such as stanchions. Therefore, the manufacturing cost can be reduced.
