Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking facility, and more particularly, it is installed in a building having a vibration isolation structure between a ground structure portion and an underground structure portion, and the ground structure portion thereof is installed. The present invention relates to an improvement in the structure of a parking facility having a loading / unloading part and a parking space in an underground structure.

[0002]

2. Description of the Related Art Conventionally, as a mechanical parking facility, for example, as disclosed in Japanese Patent Laid-Open No. 4-140370, there is a parking facility in the ground and a parking space in the underground. Are known. In this type of mechanical parking facility, a hoistway for transporting a vehicle is formed across the loading / unloading section and the parking space, and a hoisting lift for hoisting a pallet for supporting the vehicle is formed in the hoistway. It is equipped.
Then, when the vehicle is loaded, the vehicle is placed on the pallet located in the loading / unloading section, and the lifting lift lowers the pallet in the hoistway to transport the vehicle together with the pallet into the parking space. On the other hand, at the time of warehousing, a pallet on which a desired vehicle in the parking space is placed is moved to an elevating lift, and the pallet is raised in the hoistway to convey the vehicle to the warehousing / unloading section.

A deck is provided in the loading / unloading section between the outer edge of the pallet located in the loading / unloading section and the opening peripheral edge of the floor of the loading / unloading section, which is the upper end of the hoistway. The gap between the pallet and the peripheral edge of the floor opening is set small by the deck, for example, 30 mm to 40 mm. As a result, when the pallet is located in the loading / unloading section,
The deck and the pallet are positioned substantially flush with each other with a slight gap therebetween, which makes it easy for a vehicle or a person to enter or leave the pallet.

[0004]

By the way, this type of mechanical parking facility is installed in a building having a vibration isolation structure, that is, a building in which it is difficult to transmit the vibration of the underground structure portion to the ground structure portion. In this case, if the conventional structure is used, the following problems occur when an earthquake occurs.

That is, as a general structure of this vibration isolating structure, an elastic body such as a vibration isolating rubber is interposed between the above-ground structure portion and the underground structure portion of the building, and an earthquake occurs. Even if the underground structure part sometimes vibrates, it is absorbed by the elastic body, so that it is difficult to be transmitted to the above-ground structure part. That is, even if the amplitude of the underground structure is large, the amplitude of the aboveground structure is small.

When the above-mentioned parking facility is installed in a building having such a structure, the loading / unloading section is generally provided in the above-ground structure portion, so that the entire parking facility is in the underground structure portion of the building. While it is fixedly supported by
The floor opening of the loading / unloading section will be formed in the above-ground structure. Therefore, when the pallet is located in the loading / unloading section, the pallet faces the deck of the above-ground structure, and the outer edge of the pallet and the edge of the deck are close to each other.

When an earthquake occurs in such a state, the underground structure part vibrates with a large amplitude due to the above-described vibration isolation structure, while the ground structure part has a small amplitude. Further, the lifting lift fixedly supported by the underground structure portion and the pallet supported by the lifting lift vibrate with a large amplitude together with the underground structure portion. In other words, while the pallet vibrates with a large amplitude, the amplitude of the decks arranged close to it is small. Therefore, the pallet collides with the deck, and the deck regulates the fluctuation of the pallet, which may cause a failure of the lift and the pallet or damage to the deck.

The present invention has been made in view of this point, and an object thereof is to put a pallet in and out of a mechanical parking facility applied to a building having a vibration isolation structure when an earthquake occurs. Another object of the present invention is to eliminate the problem caused by the fluctuation of the pallet being restricted by colliding with the opening edge of the floor of the section.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention prevents fluctuations in the relative position of the pallet with respect to the above-ground structure portion when the pallet vibrates with a large amplitude such as when an earthquake occurs. Made possible

Specifically, the invention according to claim 1 is installed in a building provided with a vibration isolation structure for suppressing the vibration of the underground structure portion from being transmitted to the aboveground structure portion, and the underground structure portion is installed in the building. The vehicle is fixedly supported, and one end of the vehicle is opened in the floor surface of the loading / unloading portion provided in the above-ground structure portion, and the vehicle is provided inside the vehicle transport path formed from the floor surface of the loading / unloading portion to the underground structure portion. Equipped with a vehicle transporting means for raising and lowering a supporting pallet and a parking equipment main body installed inside the underground structure portion and having a parking space for the vehicle, and raising and lowering the pallet on which the vehicle is placed in the vehicle transport path. Then, the loading operation of transporting the vehicle from the loading / unloading section toward the parking space and the loading operation of transporting the vehicle from the parking space toward the loading / unloading section are performed, and the pallet is positioned in the loading / unloading section. Vehicle entry into pallet Exit is based on the premise can be the difference between the mechanical parking equipment. Further, when the vibration of the above-mentioned underground structure portion occurs, a variation permitting means is provided for allowing the relative position of the pallet to vary with respect to the above-ground structure portion.

With such a structure, when the vehicle is loaded and unloaded, the vehicle is moved into the pallet located in the loading / unloading section and the vehicle is placed on the pallet. Then, the vehicle is lowered from the loading / unloading section to the parking space. On the other hand, during the unloading operation of the vehicle, the pallet on which the vehicle is placed in the parking space is lifted in the vehicle transportation route by the vehicle transportation means, and the vehicle is transported from the parking space toward the warehousing / discharging unit, Exit the vehicle from the pallet at. When the pallet is located in the loading / unloading area, if the underground structure part vibrates due to an earthquake or the like, the vibration isolation structure causes the aboveground structure part to vibrate with a smaller amplitude than the underground structure part. Will be done. The opening on the floor of the loading / unloading section provided in the above-ground structure also vibrates with a smaller amplitude than the pallet. In such a situation,
Since the relative position of the pallet with respect to the above-ground structure portion can be changed by the change allowance means, the pallet collides with the opening peripheral edge of the floor surface of the loading / unloading section, and this opening peripheral edge prevents the pallet from changing. There will be no situation where the pallet is regulated and the pallet is damaged.

According to a second aspect of the present invention, in the mechanical parking facility according to the first aspect, the fluctuation allowance means is used to set the height position of the pallet to the ground structure when the pallet is located in the loading / unloading section. It is configured such that it is located above the floor surface of the loading / unloading part in the part. With this configuration, the pallet with a large amplitude and the floor surface of the loading / unloading section with a small amplitude have different height positions in the horizontal direction, and when a horizontal vibration occurs, the pallet is loaded. They do not collide with each other because they overlap the floor surface of the shipping section.

According to a third aspect of the present invention, in the mechanical parking facility according to the first aspect, the variation allowance means is provided such that the height position of the pallet is set to the loading / unloading section when the pallet is in the loading / unloading section. While substantially matching the floor surface, a gap larger than the amplitude of vibration generated in the underground structure is formed between the outer edge of the pallet and the opening peripheral edge of the floor of the loading / unloading section, while the loading / unloading section is formed. Extending inward from the opening edge of the floor surface, the outer edge of the pallet that fluctuates when vibration of the underground structure part abuts, and a slide deck that can slide according to this pallet fluctuation is provided. The configuration is made by doing. With this configuration, when the pallet vibrates in the horizontal direction and contacts the slide deck, the slide deck slides due to the pressing force from the pallet. Therefore, the impact force when the pallet comes into contact with the slide deck is alleviated and they are not damaged.

According to a fourth aspect of the present invention, in the mechanical parking equipment according to the third aspect, the slide deck is slidably movable with respect to a fixed bracket provided at an opening peripheral edge portion of the floor surface of the loading / unloading section. The slide deck and the fixed bracket are supported so that when the pallet is not in contact with the slide deck, the slide deck is relatively immovably connected to the fixed bracket, while the slide deck is in contact with the slide deck. The connecting member for releasing the connection state to the fixed bracket and allowing the slide deck to slide and move with respect to the fixed bracket is provided. With this configuration, in a state where no earthquake occurs, the slide deck is connected to the fixed bracket by the connecting member so that the slide bracket cannot move relatively, and thus the slide deck is held at a predetermined position without sliding. On the other hand, when a pallet that vibrates due to an earthquake contacts the slide deck, the pressing force from this pallet releases the connecting state of the connecting members, and the slide deck becomes slidable with respect to the fixed bracket. Therefore, the same effect as that of the invention described in claim 3 can be obtained.

The approaching and exiting directions are shown by arrows in FIGS. 4 and 5. That is, the loading / unloading opening 7a is formed inside the decks 16 and 17. Hereinafter, the fixed deck 16 and the slide deck 17 will be described.

The fixed deck 16 is, as shown in FIG.
It is supported on the upper surface of a fixed bracket 18 provided at the edge of the opening 13 of the ground structure portion B. The fixing bracket 18 has a horizontal frame 18a extending horizontally from the edge of the opening 13 toward the center of the opening 13, and an inclination erected between the tip of the horizontal frame 18a and the edge of the opening 13. It is composed of a frame 18b.

Then, as shown in FIG. 4, the fixed deck 1 is arranged so as to face the front edge 5a and the left and right side edges 5b and 5c of the pallet 5 which are located on the loading / unloading port A1 side.

A gap α (for example, 30
0 mm) is installed in the position. The fixed decks 16a, 16b, 16c are fixed to the upper ends of leg members 16e extending upward from the side surface of the horizontal frame 18a of the fixed bracket 18, as shown in FIGS. On the other hand, the fixed deck 16d arranged so as to face the rear edge 5d of the pallet 5 is close to the rear edge 5d of the pallet 5 and is directly fixed to the upper surface of the horizontal frame 18a of the fixed bracket 18 to be fixed to the pallet 5. On the other hand, it is located below with a slight dimension β (see FIG. 5).

On the other hand, the slide deck 17 includes the pallet 5
Is provided only in the portion facing the front edge portion 5a and the left and right side edge portions 5b, 5c, and closes the gap α. These slide decks 17 (17a, 17b, 17c) are
It is supported on a horizontal frame 18a of a fixed bracket 18 so as to be slidable with respect to the fixed deck 16. The support structure of the slide deck 17 will be described below.

This slide deck 17 is shown in FIGS.
As shown in FIG. 5, a connecting member 19 having a U-shaped cross section is attached to the lower surface of the connecting member 19 and is open to the longitudinal center of the slide deck 17. A slider 20 is attached to the lower surface of the connecting member 19. The slider 20 includes an upper side portion 20a attached to the lower surface of the connecting member 19 and the upper side portion 2a.
Vertical side portion 20b extending downward from the center of the width method of 0a
And a lower side portion 20c extending in the horizontal direction from the lower end of the vertical side portion 20b to the left and right sides of the vertical side portion 20b. Further, rollers 21, 21, ... Which are rotatable around an axis extending in the horizontal direction are provided on both sides of the vertical side portion 20b. The rollers 21 are respectively arranged at two positions with a predetermined distance from both side ends of the slider 20 in the longitudinal direction.

On the other hand, on the upper surface of the horizontal frame 18a of the fixed bracket 18, a roller support member 22 having an open U-shaped cross section is attached so as to surround the lower side and both the left and right sides of the slider 20. The support shafts of the rollers 21, 21, ... Are supported by the vertical surfaces 22a, 22a of the roller support member 22, respectively. That is, as the slider 20 slides in the left-right direction in FIG. 6 while being guided by the rollers 21, 21 ,.
The slide deck 17, which is attached to the fixed deck 16 and the fixed bracket 18 via the connecting member 19, is also slidable (see the phantom line in FIG. 6).

Further, a horizontal portion 23a attached to the lower surface of the lower side portion 20c is provided at one end portion (left end portion in FIG. 6) of the slider 20, and the horizontal portion 23a is bent downward from one end edge of the horizontal portion 23a and fixed as described above. Horizontal frame 18a of bracket 18
A spring support bracket 23 having a vertical portion 23b located on the side of is provided. A coil spring 24 is installed between the vertical portion 23b of the spring support bracket 23 and the side surface of the horizontal frame 18a of the fixed bracket 18. As a result, when the slider 20 slides to the left in FIG. 6, this coil spring 24 extends (see the phantom line in FIG. 6) and applies a biasing force to the slider 20 in the direction opposite to the sliding direction. Has become. Further, a stopper 25 is provided on the vertical side portion 20b of the slider 20. This stopper 25 is in contact with the outer peripheral surface of one roller 21 in the initial position (position shown in FIG. 6) in which the slide deck 17 is not sliding, and is on the pallet 5 side of the slider 20 (see FIG. 6). To the right). As a result, the position of the slide deck 17 when the stopper 25 is in contact with the roller 21 is regulated as the moving end of the slide movement to the right.

The lower side portion 20c of the slider 20 is
A shear pin 26 as a connecting member for restricting a relative displacement between the fixed frame 18 and the horizontal frame 18a of the fixed bracket 18 is provided. That is, through holes (not shown) are formed in the lower side portion 20c of the slider 20 and the fixed bracket 18 at positions facing each other in the initial position shown in FIG.
The shear pin 26 is inserted through these through holes. The shear pin 26 is slightly tapered toward the bottom, and the diameter of the upper end is set to be slightly larger than the diameter of the through hole of the slider 20 so that it does not fall off from each through hole. It has become. With this configuration, when the slide deck 17 slides to the left in FIG. 6 due to the action of the external force, the shear pin 26 is broken and the above restriction is released.

With the above configuration, the variation permitting means 30 is configured to permit variation of the relative position of the pallet 5 with respect to the ground structure portion B when an earthquake occurs.

Next, the loading / unloading operation of the main parking facility 1 will be described. First, at the time of the warehousing operation, the empty pallet 5 on which the vehicle W is not mounted is searched from among the pallets 5, 5, ... Inside the parking space S, and the lift fork 10 is lowered to a position corresponding to the parking space S. .
Then, the empty truck pallet 5 found is lifted by the fork 1
After placing it on 0, the lift fork 10 is raised to position the empty vehicle pallet 5 in the loading / unloading section A. In this state, the opening / closing door 11 of the loading / unloading section A is opened to allow the vehicle W to enter the loading / unloading section A, the vehicle W is moved onto the empty pallet 5, and the lift fork 10 is again used for the parking space S. And the pallet 5 on which the vehicle W is placed is moved to the parking space S. This ends the warehousing operation.

On the other hand, during the unloading operation, the pallet 5 on which the vehicle W requiring the unloading is placed is searched, and the lift fork 10 does not place the pallet 5 on the hoistway 8.
Wait at the bottom edge of. Then, the retrieved pallet 5 moves onto the lift fork 10 and the lift fork 10
Goes up to the loading / unloading section A. In this state, the opening / closing door 11 of the loading / unloading section A is opened to permit the exit of the vehicle W from the loading / unloading section A. This completes the shipping operation.

The characteristic operation of this embodiment is when an earthquake occurs. That is, as shown in FIGS. 2 and 4, when an earthquake occurs in a state where the pallet 5 is located in the loading / unloading section A, in the underground structure portion C of the building, the pallet 5 is relatively moved according to the seismic intensity of the earthquake. It will oscillate with a large amplitude (see the phantom line in FIG. 2). On the other hand, the ground structure part B
Vibrates with an amplitude smaller than that of the underground structure portion C due to the above-described vibration isolation structure. Therefore, in the loading / unloading section A, the amplitude of the pallet 5 is larger than the amplitude of the loading / unloading opening 7a of the loading / unloading section A.

Now, assuming that the vibration direction is the left-right direction of FIGS. 4 and 5, when the pallet 5 moves to the right, the pallet 5 moves above the fixed deck 16d on the rear side. It will be. In other words, in this portion, the height position of the pallet 5 is set higher than the height position of the fixed deck 16d by the dimension β, so that the amplitude of the pallet 5 is larger than the amplitude of the fixed deck 16d. However, since the pallet 5 and the fixed deck 16d overlap each other in the vertical direction, the two pallets 5 and 16d do not collide with each other.

On the other hand, when the pallet 5 moves leftward, the pallet 5 contacts the front slide deck 17a, and a leftward pressing force acts on the front slide deck 17a. As a result, the pressing force also acts on the slider 20, and the shear pin 26 connecting the slider 20 and the fixed bracket 18 is cut,
The connected state of both 18 and 20 is released. Therefore, the slide deck 17a slides according to the movement of the pallet 5. That is, when the pallet 5 moves to the left, the pallet 5 pushes the slide deck 17a to move the slide deck 17a to the left (see the phantom line in FIG. 6). At this time, the coil spring 24 expands along with the movement of the slider 20, and applies a pressing force to the slider 20 in the right direction in FIG. When the pallet 5 moves rightward from this state, the pressing of the pallet 5 against the slide deck 17a is released, and the slide deck 17a returns to the original position by the urging force of the coil spring 24. As the pallet 5 moves in the left-right direction (vibration), the slide deck 17a also slides, and when the pallet 5 returns to the initial position after the earthquake, the slide deck 17a is also urged by the coil spring 24. It returns to the initial position shown by the solid line in FIG. Further, in this state, the stopper 25 is in contact with the roller 21. That is, the pallet 5 and the slide deck 17a return to the state of facing each other with a slight gap.

When the vibration is generated in the up-down direction in FIG. 4 (the direction in which the phase is horizontally shifted by 90 ° with respect to the vibration direction described above), the slide movement similar to that of the slide deck 17a described above is performed. Is performed on the slide decks 17b and 17c located on both the left and right sides of the pallet 5. In addition, when vibrations other than these occur in the horizontal direction, each slide deck 17a, 1
Both 7b and 17c are slid.

As described above, according to this embodiment, the pallet 5 is
And the opening 13 of the loading / unloading section A into the fixed deck 1
The pallet 5 moves above and below the fixed deck 16d at the trailing edge of the pallet 5 when an earthquake occurs, while allowing the vehicle W to enter and leave the pallet 5 by being closed by the 6 and the slide deck 17. Since the slide deck slides in accordance with the movement of the pallet 5 at the front edge portion and the left and right side edge portions of the pallet 5, the pallet collides with the deck as in the conventional case, and the deck does not move. It is possible to prevent the fluctuations from being regulated and causing a failure of the lifting mechanism or damage to the pallet or the deck. Therefore, it is possible to solve the conventional problem when the mechanical parking facility is installed in a building provided with a vibration isolation structure that suppresses the transmission of the vibration of the underground structure portion C to the ground structure portion B.

Although the horizontal circulation type parking facility has been described in the present embodiment, the present invention is not limited to this, and may be adopted in a box type circulating type parking facility. Further, the loading / unloading section A is not limited to one location, and may be provided in two or more locations.

Further, although the parking facility having only one parking space has been described in the present embodiment, the present invention may be applied to a parking facility having a plurality of parking spaces vertically.

Further, in the present embodiment, the fixed deck 16 and the slide deck 17 are arranged on the front side and the left and right sides of the pallet 5, and only the fixed deck 16 having a low height position is arranged on the rear side. The present invention is not limited to this, and the pallet 5
The slide deck 17 is arranged to face the entire circumference of
Alternatively, a configuration in which only the fixed deck 16 having a low height position is arranged may be adopted.

[0038]

As described above, according to the present invention, the following effects can be obtained. First, according to the invention described in claim 1, it is installed in a building provided with a vibration isolation structure that suppresses the transmission of vibration of the underground structure portion to the ground structure portion, and a parking space is provided in the underground structure portion above the ground. For mechanical parking equipment that has a loading / unloading part in the structure part, when the underground structure part vibrates due to an earthquake or the like, it is possible to change the relative position of the vehicle support pallet to the above-ground structure part. Since the fluctuation permitting means is provided, the peripheral edge of the opening of the floor of the loading / unloading part regulates the fluctuation of the pallet, and the pallet is not damaged, so that the reliability and practicality of the parking facility can be improved. Can be planned.

According to the second aspect of the invention, the variation permitting means is arranged such that, in a state where the pallet is located in the loading / unloading section, the height position of the pallet is set to be higher than the floor surface of the loading / unloading section in the above-ground structure. Since it is located above, it is possible to avoid a collision between the pallet and the floor surface of the loading / unloading section with a simple structure, and it is possible to obtain a highly practical fluctuation allowance means.

According to the third aspect of the invention, as the fluctuation permitting means, the outer edge of the fluctuating pallet is in contact with the pallet and the deck is slidably movable according to the fluctuation of the pallet. While the height position of the upper surface of the pallet is aligned with that of the pallet, fluctuation of the pallet can be allowed when vibration occurs, so it is possible to easily move the vehicle in and out of the pallet, and damage such as an earthquake. Can be avoided.

According to the fourth aspect of the present invention, while the pallet is not in contact with the slide deck, the slide deck is connected to the fixed bracket in a relatively immovable manner, while the pallet is in contact with the slide deck. Since the connecting member for releasing the connection state to the fixed bracket and allowing the slide deck to slide freely with respect to the fixed bracket is provided, the slide deck can be held at a predetermined position in the normal state, and the slide can be slid carelessly. The deck does not slide. Therefore, it is possible to allow the movement of the pallet by allowing the slide deck to slide only when an earthquake occurs, while allowing vehicles and people to easily enter and leave the pallet.
