Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking system, and more particularly to a building having a vibration isolating structure between an above-ground structure and an underground structure. The present invention relates to an improvement in a structure of a parking facility having a parking space in an underground structure and an entrance / exit unit in an underground structure. 2. Description of the Related Art Conventionally, as a mechanical parking facility, for example, as shown in Japanese Patent Application Laid-Open No. 4-140370, a parking space is provided in an underground part and a parking part is provided in an underground part. Are known. In this type of mechanical parking equipment, a hoistway for transporting a vehicle is formed between the entrance / exit section and the parking space, and an elevating lift for elevating a pallet for supporting a vehicle is formed on the hoistway. Provided.
At the time of entry of the vehicle, the vehicle is placed on a pallet located at the entry / exit section, and the pallet is lowered in the hoistway by an elevating lift, and the vehicle is transported to the parking space together with the pallet. On the other hand, at the time of unloading, the pallet on which the desired vehicle is placed in the parking space is moved to the elevating lift, the pallet is raised in the hoistway, and the vehicle is transported to the loading / unloading section. Further, a deck is provided between the outer edge of the pallet located at the entrance / exit section and the opening edge of the floor of the entrance / exit section at the upper end of the hoistway. The gap between the pallet and the peripheral edge of the floor opening is set small, for example, to 30 mm to 40 mm by the deck. With this, when the pallet is located in the loading / unloading section,
The deck and the pallet are located substantially flush with each other with a slight gap therebetween, thereby facilitating entry and exit of vehicles and persons to and from the pallet. [0004] By the way, a mechanical parking facility of this type is provided with a vibration-isolated structure, that is, a building in which it is difficult to transmit the vibration of the underground structure to the above-ground structure. However, if the conventional structure is used, the following problems occur when an earthquake occurs. [0005] In other words, a typical vibration-isolating structure is one in which an elastic body such as an anti-vibration rubber is interposed between the above-ground structure portion and the underground structure portion of the building. Sometimes, even if the underground structure part vibrates, it is absorbed by the elastic body, so that it is hardly transmitted to the above-ground structure part. That is, even if the amplitude of the underground structure is large, the amplitude of the above-ground structure is small. [0006] When the above-described parking facility is installed in a building having such a configuration, the entrance / exit section is generally provided in the above-ground structure, and the entire parking facility is provided in the underground structure of the building. While being fixedly supported
The opening of the floor of the entrance / exit section is formed in the above-ground structure. For this reason, 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 located close to each other. When an earthquake occurs in such a state, the underground structure vibrates with a large amplitude due to the above-described vibration isolation structure, whereas the amplitude of the above-ground structure becomes small. The lifting lift fixedly supported by the underground structure and the pallet supported by the lifting lift vibrate with a large amplitude together with the underground structure. In other words, while the pallet vibrates with a large amplitude, the amplitude of the deck disposed close to the pallet is small. For this reason, the pallet collides with the deck, and the deck regulates the fluctuation of the pallet, which may cause a failure of the lifting / lowering lift and damage of the pallet or the deck. The present invention has been made in view of this point, and an object of the present invention is to provide a pallet for a mechanical parking facility applied to a building having a vibration isolation structure when a pallet is moved in and out of an earthquake or the like. It is an object of the present invention to solve the problem caused by the fact that the fluctuation of the pallet is restricted by colliding with the opening edge of the floor of the pallet. In order to achieve the above object, the present invention provides a method for controlling the relative position of a pallet with respect to a ground structure when a pallet vibrates with a large amplitude during an earthquake or the like. Was made possible. Specifically, the invention according to claim 1 is installed in a building provided with a vibration isolation structure that suppresses transmission of vibration of an underground structure portion to an above-ground structure portion. The vehicle is fixedly supported and has one end opening to the floor of the entrance / exit section provided in the above-ground structure portion, and the vehicle inside the vehicle transport path formed from the floor of the entrance / exit section to the underground structure portion. A vehicle transporting means for raising and lowering a supporting pallet; and a parking facility main body installed inside the underground structure portion and having a parking space for the vehicle, and the pallet on which a vehicle is mounted is raised and lowered in a vehicle transport path. A parking operation for transporting the vehicle from the parking area to the parking space, and a parking operation for transporting the vehicle from the parking space to the parking area, so that the pallet is positioned in the parking area. Vehicle approach to pallet Exit is based on the premise can be the difference between the mechanical parking equipment. And the pallet is the above-mentioned loading / unloading section
With the outer edge of the pallet and the floor of the loading / unloading section

The material is provided . [0011] With such a configuration, at the time of the warehousing operation of the vehicle, the vehicle enters the pallet located at the loading / unloading section, and the vehicle is placed on the pallet. To convey the vehicle from the entrance / exit section toward the parking space. On the other hand, at the time of the vehicle leaving operation, the pallet on which the vehicle is placed in the parking space is raised in the vehicle transport path by the vehicle transport means, and the vehicle is transported from the parking space toward the entrance / exit portion, and the entrance / exit portion is moved. The vehicle is withdrawn from the pallet at. Then, when the pallet is located in the loading / unloading section, an earthquake
When the slide deck is not in
It is connected to the fixed bracket so that it can not move relatively,
Therefore, the slide deck does not slide
It is held at a predetermined position. On the other hand, when vibration occurs in the underground structure due to the occurrence of an earthquake or the like, the above-ground structure vibrates at a smaller amplitude than the underground structure due to the vibration isolation structure. Then, the opening on the floor of the entrance / exit section provided in the above-mentioned ground structure also vibrates with a smaller amplitude than that of the pallet. In such a situation, when the pallet which oscillates with the generation of the earthquake is in contact with the slide deck, the slide deck connected state is released of the connecting member by the pressing force from the pallet relative to the fixed bracket The slide deck can be moved freely, and the slide deck
The slide moves by the pressing force from the let. others

More specifically, vibration isolating members 2 each provided with an anti-vibration rubber 2a are interposed at a plurality of locations between the above-ground structure portion B and the underground structure portion C, so that when an earthquake occurs, the underground structure 2 The vibration of the portion C is sucked by the vibration isolation member 2 and is hardly transmitted to the above-ground structure portion B. In other words, in this building, the amplitude of the underground structure portion B is smaller than the amplitude of the underground structure portion C (the phantom line in FIG. 2 indicates the displacement of the underground structure portion C when vibration occurs). It has a vibration function. Next, the parking facility 1 installed in this building will be described. As shown in FIG. 3, two vertical rails 3 and 3 and two horizontal rails 4 and 4 are provided in a rectangular shape on the floor portion F of the parking space S, and the lower surface side of the pallet 5 for mounting on a vehicle.

The vehicle W can enter and exit the pallet 5 in the loading / unloading section A (the vehicle W with respect to the pallet 5).
4 and 5 are indicated by arrows in FIG. 4 and FIG. 5). In other words, the above-mentioned opening / closing opening 7a is formed inside these decks 16 and 17. Hereinafter, the fixed deck 16 and the slide deck 17 will be described. As shown in FIG. 6, the fixed deck 16
It is supported on the upper surface of a fixed bracket 18 provided at the edge of the opening 13 of the ground structure B. The fixing bracket 18 has a horizontal frame 18 a extending horizontally from the edge of the opening 13 toward the center of the opening 13, and an inclined bridge extending over the tip of the horizontal frame 18 a and the edge of the opening 13. And a frame 18b. Then, as shown in FIG. 4, the fixed deck 1 disposed opposite to the front edge 5a and the left and right side edges 5b, 5c of the edges of the pallet 5 located on the side of the loading / unloading port A1.
6a, 16b, and 16c are each edge 5 of the pallet 5.
a, 5b, 5c and a gap α of a predetermined size (for example, 30
0 mm). 6 and 7, the fixed decks 16a, 16b, and 16c are fixed to the upper ends of leg members 16e extending upward from the side surfaces of the horizontal frame 18a of the fixed bracket 18. On the other hand, the fixed deck 16d arranged opposite to 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, and On the other hand, it is located below with a small dimension β (see FIG. 5). On the other hand, the slide deck 17
And is provided only in a portion facing the front edge portion 5a and the left and right side edge portions 5b and 5c to close the gap α. These slide decks 17 (17a, 17b, 17c)
The fixed bracket 18 is supported on a horizontal frame 18 a so as to be slidable with respect to the fixed deck 16. Hereinafter, the support structure of the slide deck 17 will be described. The slide deck 17 is shown in FIGS.
As shown in FIG. 2, a connecting member 19 having a U-shaped cross section is mounted on the lower surface and opened to the center in the longitudinal direction of the slide deck 17, and a slider 20 is mounted on the lower surface of the connecting member 19. The slider 20 has an upper side 20a attached to the lower surface of the connecting member 19 and an upper side 2a.
Vertical side 20b extending downward from the center in the width method of 0a
And a lower side portion 20c extending horizontally from the lower end of the vertical side portion 20b to the left and right sides in a horizontal direction. 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 disposed at two places at a predetermined distance from both ends in the longitudinal direction of the slider 20. On the upper surface of the horizontal frame 18a of the fixed bracket 18, a roller support member 22 having a U-shaped cross section with an open upper portion is attached so as to surround the lower side and both right and left sides of the slider 20. The shafts of the rollers 21, 21,... Are supported on the respective vertical surfaces 22a, 22a of the roller support member 22. That is, the slider 20 slides in the left and right direction in FIG. 6 while being guided by the rollers 21, 21,.
The slide deck 17 attached to the fixed deck 16 via the connecting member 19 is also slidable with respect to the fixed deck 16 and the fixed bracket 18 (see the phantom line in FIG. 6). At one end (left end in FIG. 6) of the slider 20, a horizontal portion 23a attached to the lower surface of the lower side portion 20c is bent downward from one edge of the horizontal portion 23a. Horizontal frame 18a of bracket 18
And a vertical portion 23b located on the side of the spring support bracket 23. A coil spring 24 is provided 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. Thus, when the slider 20 slides to the left in FIG. 6, the coil spring 24 extends (see the phantom line in FIG. 6), and applies an urging force to the slider 20 in a direction opposite to the sliding direction. Has become. Further, a stopper 25 is provided on the vertical side portion 20 b of the slider 20. The stopper 25 is in contact with the outer peripheral surface of one of the rollers 21 in a state where the slide deck 17 is at the initial position (the position shown in FIG. 6) in which the slide deck 17 is not slid, and the stopper 25 is on the pallet 5 side (see FIG. Right). As a result, the position of the slide deck 17 in a state where the stopper 25 is in contact with the roller 21 is regulated as a moving end of the rightward sliding movement. The lower side portion 20c of the slider 20
Between the horizontal frame 18a of the fixed bracket 18 and the horizontal frame 18a, a shear pin 26 as a connecting member for regulating the relative displacement between the two 20c and 18a 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 at the initial position shown in FIG.
A shear pin 26 is inserted through these through holes. Note that the shear pin 26 is tapered slightly toward the lower portion, and the diameter of the upper end portion is set slightly larger than the diameter of the through hole of the slider 20 so that it does not fall out of each through hole. It has become. With such a configuration, when the slide deck 17 is slid to the left in FIG. 6 by the action of an external force, the shear pin 26 is broken, and the above restriction is released. With the above configuration, the fluctuation permitting means 30 is configured to change the relative position of the pallet 5 with respect to the above-ground structure portion B when an earthquake occurs. Next, a description will be given of the entry / exit operation in the parking facility 1. First, at the time of the parking operation, among the pallets 5, 5,... In the parking space S, an empty pallet 5 on which the vehicle W is not mounted is searched, and the lift fork 10 is lowered to a position corresponding to the parking space S. .
Then, the retrieved empty pallet 5 is transferred to the lift fork 1
Then, the lift fork 10 is raised, and the empty pallet 5 is positioned at 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 placed in the parking space S. The pallet 5 on which the vehicle W is placed is moved to the parking space S. Thereby, the storage operation ends. On the other hand, at the time of the unloading operation, the pallet 5 on which the vehicle W required to be unloaded is placed is searched, and the lift fork 10 is placed without the pallet 5 on the hoistway 8.
Wait at the lower end of the. Thereafter, the retrieved pallet 5 moves on the lift fork 10 and the lift fork 10
Rises to the loading / unloading section A. In this state, the opening / closing door 11 of the entrance / exit unit A is opened to permit the vehicle W to exit the entrance / exit unit A. Thus, the retrieval operation ends. The feature of the present 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 at the loading / unloading section A, the underground structure portion C of the building is relatively in accordance with the seismic intensity of this earthquake. It will oscillate with a large amplitude (see the phantom line in FIG. 2). In contrast, the ground structure part B
Is vibrated with a smaller amplitude than 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 horizontal direction in FIGS. 4 and 5, when the pallet 5 moves rightward, the pallet 5 moves above the fixed deck 16d on the rear side. Will be. That is, in this part, the height of the pallet 5 is set to be higher than the height 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 in the vertical direction, the two 5 and 16d do not collide with each other. On the other hand, when the pallet 5 moves to the left, the pallet 5 comes into contact with 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 fixing bracket 18 is cut off.
The connection between the two 18 and 20 is released. Therefore, the slide deck 17a slides in accordance with the movement of the pallet 5. That is, when the pallet 5 moves to the left, the pallet 5 presses the slide deck 17a, so that the slide deck 17a also moves to the left (see the phantom line in FIG. 6). At this time, the coil spring 24 expands with the movement of the slider 20, and applies a pressing force to the slider 20 rightward 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 (vibrates) in the left-right direction, the slide deck 17a also slides. When the pallet 5 returns to the initial position after the earthquake, the slide deck 17a is also moved by the urging force of the coil spring 24. It returns to the initial position shown by the solid line in FIG. 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 a state where they face each other with a slight gap. When the vibration is generated in the vertical direction in FIG. 4 (a direction shifted by 90 ° in the horizontal direction with respect to the above-described vibration direction), the same sliding movement as the above-described slide deck 17a is performed. Is performed in each of the slide decks 17b and 17c located on the left and right sides of the pallet 5. In addition, when vibration occurs in a horizontal direction other than the above, each slide deck 17a, 1
The slide movement is performed in both 7b and 17c. As described above, according to the present embodiment, the pallet 5
And the gap between the opening 13 of the loading / unloading section A and 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 the vehicle W can enter and exit the pallet 5 by being closed by the slide deck 6 and the slide deck 17. 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, so that the pallet collides with the deck and the deck By restricting the fluctuation, it is possible to avoid the failure of the lifting mechanism and the damage of the pallet or the deck. Therefore, it is possible to solve the conventional problem in a case where a mechanical parking facility is installed in a building having a vibration isolation structure that suppresses transmission of vibration of the underground structure portion C to the above-ground structure portion B. Although the embodiment has been described with reference to the horizontal circulation type parking facility, the present invention is not limited to this, and may be configured to be adopted in a box type circulation type parking facility. Also, the configuration may be such that the loading / unloading section A is not limited to one location but is provided at two or more locations. In this embodiment, a parking facility having only one parking space has been described. However, the present invention may be applied to a parking facility having a plurality of parking spaces in a vertical direction. In the present embodiment, the fixed deck 16 and the slide deck 17 are provided on the front side and the left and right sides of the pallet 5, and only the fixed deck 16 having a low height is provided on the rear side. The present invention is not limited to this.
The slide deck 17 is arranged facing the entire circumference of
Alternatively, a configuration in which only the fixed deck 16 having a low height is provided may be employed. As described above, according to the present invention ,
