Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story parking system, and more particularly to a multi-story parking system in which a large number of vehicles can be selectively moved with a small number of driving means.

[0002]

2. Description of the Related Art Conventionally, various types of multi-story parking systems have been proposed in order to effectively use a space and secure a large number of parked vehicles. 2. Description of the Related Art A multi-tiered multi-level parking apparatus that raises and lowers a parking pallet between upper and lower three-tiered parking spaces is known.

An example of such a conventional multi-tiered multi-level parking device will be described by taking an upper and lower two-tiered parking device as an example. This is a parking space on the ground surface facing the entrance / exit road surface of a vehicle and its upper part. To or from the space (or underground space in the pit format)
A parking pallet is provided so that it can be raised and lowered, and a parking space for one car is secured on this parking pallet.
Another vehicle can be parked in the space on the ground surface created by raising (or lowering) a pallet (hereinafter referred to as “elevating pallet”) as a parking platform that can be raised or lowered. It is a device for parking another vehicle by using the space above (or below) the space.

By the way, although this multi-stage multi-story parking system may be used in a single number, in many cases, a plurality of such multi-story parking systems are installed in parallel, and in the case where a plurality of such multi-level parking systems are installed in parallel. It has been proposed to further improve the functionality of the device, improve the usability, and reduce the cost of the device by taking advantage of the structural characteristics of the device.

For example, a pallet that does not move up and down but can traverse between adjacent devices on the ground surface (hereinafter referred to as "ground traverse pallet") is installed by one less than the number of parallel devices, and the ground traverse pallet is an adjacent unit. By moving between the parking devices, the empty space (space without a vehicle) is moved to that position so that the lifting pallet at any position can be selected and lifted, and the vehicle on the lifting pallet at any position can be moved. It is known that the warehousing is easy.

[0006] Further, the structure of a lifting drive mechanism for lifting the lifting pallets is simplified, for example, a hydraulic cylinder device or a motor, which is a driving means, is also used to drive a plurality of lifting pallets installed in parallel. Equipment that reduces the equipment cost by using less driving means than the number of installed units, and the upper and lower 3
In a multi-tiered parking system with a single drive, the upper and lower parking pallets can be moved up and down.
A shared device is also known (Japanese Patent Laid-Open No. 30418/1991).
No. 1).

One driving means (motor or the like) can be used for both the raising and lowering movements of the above-mentioned adjoining devices, or the raising and lowering movements of the upper and lower raising and lowering pallets of the three-stage type multi-level parking device can be performed by one. Both of the methods in which a motor or the like is commonly used and shared are advantageous in that the cost can be reduced and the burden of maintenance management can be reduced as compared with the method in which a motor or the like is provided for each lifting pallet.

[0008]

However, in the former case in which a motor or the like is shared and shared between adjacent lifting pallets, the number of motors can be reduced by half when the number of parallel units is an even number, but when the number of parallel units is an odd number. There are parts that can be shared and parts that cannot be shared, and standards for common motors and their associated chain mechanisms, etc. and standards for the remaining one motor for independent drive and its associated chain mechanisms, etc. There is a problem in that it is not necessarily efficient because the number of parts with different specifications increases because they must be prepared and installed separately.

Further, there is a problem that the system in which the motors and the like for the upper and lower lifting pallets are shared and shared cannot be applied to the two-stage multi-level parking apparatus.

These problems are particularly problematic when a multilevel parking device is installed in a parking lot under the building.
In other words, in the underground parking lot of the building, the space between columns is restricted by building standards and the like due to beam strength, etc., so in practice it is extremely common to employ a multi-story parking device with three unit parking devices side by side. In many cases, a lower two-stage multi-level parking device is adopted. In such a case, in the method in which the driving means and the like are shared and shared between the adjacent devices described above, only three motors are provided and only one can be reduced. The problem is that the same number of motors must be prepared. Further, the method of using the driving means for both the upper and lower lifting pallets as a dual purpose cannot be applied to the upper and lower two-stage type.

In order to solve the above-mentioned problems of the conventional multi-purpose parking apparatus which is also used as a driving means,
The elevating and lowering drive mechanism including the elevating and lowering pallet driving means such as a motor and the chain mechanism and the like associated therewith can be applied without restriction whether the number of units installed in parallel is odd or even, and it is a two-stage type, three-stage type. The purpose of the present invention is to provide a multilevel parking apparatus having a configuration applicable to any of the formulas.

Another object of the present invention is that theoretically there is no limit to the number of units that can be shared when the elevator drive mechanism is also used and shared, and therefore, one motor or the like for many elevator pallets depending on the design. It is an object of the present invention to provide a novel multi-level parking apparatus that can be used as a common driving means and is commonly used, and is extremely advantageous in reducing the cost of the apparatus.

Still another object of the present invention is to provide a new multi-level parking system which can reduce the burden on the power source supply system of the driving means, the power supply wiring, etc. and the maintenance and inspection work load by sharing the lifting drive mechanism. It is in the area of providing equipment.

Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 This embodiment shown in FIGS. 1 to 5 is an upper / lower two-stage multi-story parking apparatus for raising and lowering an elevating pallet with respect to the above-ground parking space. It is of the type set up.

In these drawings, reference numeral 1 denotes a frame structure of a three-dimensional parking apparatus, which is a pair of left and right front columns 101 of the parking apparatus in which three vehicles are arranged side by side (only one side is shown in FIG. 5), left and right of the whole, A total of four rear columns 102 that are erected between the unit parking devices, a front beam 103 that is an upper portion of the columns that is installed between the left and right front columns 101, and an upper column that is installed between the left and right rear columns 102. It is composed of a rear beam 104, a front beam 103, and a front and rear beam 105 installed between the tops of the rear columns 102, and three plane rectangular spaces surrounded by the beams 103 to 105 are respectively the unit parking device's space. It forms a space (see Figure 5). For each of these columns and beams, H-shaped steel is used, for example.

FIGS. 1 to 3 are views for explaining an elevating and lowering drive mechanism provided on the rear pillar 102 of the multi-storied parking apparatus, and a rope 3 as a pulling member made of wire.
The lift drive mechanism of the present example, which includes a return cylinder type hydraulic cylinder device 4 and a lock device 5 provided for each lift pallet, is arranged for each of the three unit parking devices. It is provided so that it is possible to select any one of the lifting pallets 2 and move it up and down. In the drawing, when distinguishing each lifting pallet, etc., the lifting pallet at the left side of FIG. 1 is indicated by "2 ₁ " with a suffix of ₁ , and similarly, the lifting pallet in the center is "2 ₂ " and the right pallet. The lifting pallet of 2 is indicated by "2 ₃ " (hereinafter, the same applies to other members, except for the fixed section pulley).

Explaining this structure in more detail, in this example, the rear support column 10 located in the middle of the unit parking device.
Fixed part side pulleys 6 ₁ and 6 ₂ are rotatably mounted on the upper part of 2, and a pair of pallet side pulleys 200 are mounted on the respective lifting pallets 2 near the left and right sides of the bottom part thereof.

Then, the rope 3 whose one end is connected and fixed to the rear beam 104 is connected to the pallet side pulleys 200 ₁ to 200 _3.
And rear supports 102 an upper portion of the fixed portion side pulley 6 _and 62 are wound sequentially over as shown in FIG. 1, the other end of the rope 3 that extends upward from the right end of the pallet side pulley 200 ₃ in FIG. 1 Is connected to a return cylinder type hydraulic cylinder device 4 which is a drive means.

This hydraulic cylinder device 4 of this example is installed on the rear beam 104 and has a cylinder housing 40.
From the first turning pulley 403 assembled to the rear part of 1,
After the rope 3 is turned by about 180 ° via the second turning pulley 404 attached to the tip of the piston rod 402, the other end is connected and fixed to the fixing portion. With this configuration, the piston rod 402
The required rope payout amount is secured between the storage time (see FIG. 2) and the extension time (see FIG. 1). In the figure, the extension length of the piston rod 402 of the hydraulic cylinder device 4 is shown short, but this is for the convenience of drawing.

In this example, the locking device 5 provided between each lifting pallet 2 and the rear beam 104 has hooks 500 with hooks facing outward, near the left and right sides of the upper surface of the lifting pallet 2. The rear beam 10 is fixedly provided in a pair.
4 is provided with swingable hanging hooks 501 with hooks facing inward so as to engage with these hooks 500. In the state of FIG.
The lifting pallet 2 is restricted by engaging with 0 so that the lifting pallet 2 cannot be lowered, and the lifting pallet 2 can be lifted and lowered by releasing the engagement (see FIGS. 2 and 3). In the pair of suspension hooks 501 for each lifting pallet 2, a synchronizing rod 502 pivotally connected to a position above the swing center is pivotally connected to an actuating rod 503 in the middle, and a solenoid (not shown) is excited. The operating rod 503 is moved upward so that the above engagement can be released (see FIG. 2).

Further, in this example, a safety device is provided so as to prevent the actuation rod 503 from being inadvertently moved to release the engagement. That is, as shown in detail in FIG. 4, a bracket 504 provided with a vertical through hole and a horizontal through hole is assembled to the rear beam 104, and the operating rod 503 is passed through the vertical through hole of the bracket. A horizontal through hole is formed in the operating rod so that the pin 505 can be fitted by the force of the spring 506 into the horizontal through hole of the operating rod 503 through the horizontal through hole formed in the bracket 504. It is provided in. 507, this pin 505 is the operating rod 503
It is a solenoid for pulling out from the horizontal through hole.
By doing so, the engagement of the hook can be disengaged by the upward movement of the operating rod 503 only after the pin 505 is removed from the operating rod 503 by the excitation of the solenoid 507. It is possible to obtain an advantage that the lifting pallet is not lowered due to the disengagement.

Incidentally, it is natural to provide an appropriate horizontal holding mechanism for raising and lowering the elevating pallet 2 while keeping the horizontal posture, and for example, the horizontal holding wire 8 shown in FIG.
One end of which is connected and fixed near the front side of the front and rear beams 105, and the other end is connected to a fixed part on the rear side through horizontal holding pulleys 9 and 9 assembled in a pair of front and rear on the side of the lifting pallet 2. A conventionally known one for fixing can be applied.

The lifting drive mechanism of this embodiment is constructed as described above, and its operation will be described as an example. In FIG. 1, the three lifting pallets 2 are constrained so that they cannot be lowered at the position of the upper parking space. Show. That is, in any of the lock devices 5, the hook 500 and the hanging hook 501 are in an engaged state, and the hydraulic cylinder device 4 is in a state in which the piston rod 402 is extended.

Considering the case of lowering the lifting pallet 2 ₃ at the right end of the drawing from the state of FIG. 1, first, the lock device 5 ₃ of the unit parking device is released, and then the piston rod 402 of the hydraulic cylinder device 4. Is slowly stored in the cylinder housing 401. Accordingly the rope 3 is fed from the hydraulic cylinder device 4 portion, the lift pallet 2 ₃ starts descending (see Figure 3).

[0044] Figure 2, the lift pallet 2 ₃ indicates a state in which lowered to a position on the ground the parking space (lower limit position), so that the vehicle can Receipt out against elevating pallet 2 ₃ in this state. In this example, since the pallet side pulley 200 is provided at the bottom of the elevating pallet 2, an appropriate pit 7 is provided on the ground side so as not to interfere with the entry and exit of the vehicle. It is not always necessary depending on the mounting position and the like. Further, in this state, the hydraulic cylinder device 4 is in a state in which substantially the entire length of the piston rod 402 is housed in the cylinder housing 401.

Next, from the state shown in FIG.
A lifting pallet 2 ₃ is operated in a direction of extending the piston rod 402 is gradually increased, the hook 50
0 _3, 500 ₃ is at the stage of hitting the hanging hook 501 _3, 501 _3, if free-with the operating rod 503 with respect to the pin 505 in this embodiment, the hanging Ri hook 501 _3, 5
01 ₃ lift pallet 2 ₃ of the hook 500 _3, 500 ₃
The swing naturally outward (see FIG. 3), further elevating the pallet 2 both hooks _{by 3} rises back to a state of restraining the engaging downward (see FIG. 1). In this case, it goes without saying that the hanging hooks 501 ₃ and 501 ₃ may be swung outward by a solenoid (not shown).

As described above, according to the multi-storied parking apparatus of this example, any one of the three lifting elevator pallets 2 of the unit parking apparatus is unlocked by the locking device and the hydraulic cylinder device is driven. Since it can be moved up and down, and the driving means used for this purpose can also be used as a single hydraulic cylinder device, the number of driving means can be reduced as compared with the conventional device. For example, several tens to several hundreds of unit parking devices. The benefit of reducing the drive means in the case of installing a slab is extremely large.

In this example, as shown in FIG.
If the traverse rail 10 is laid on the ground surface and the above-ground traverse pallet 11 is configured to traverse between adjacent unit parking spaces, each elevating pallet 2 can be arbitrarily raised and lowered, and thus a convenient multi-level parking device can be provided. .

Embodiment 2 This example shown in FIG. 6A shows an example in which a take-up drum type geared motor 12 is used in place of the hydraulic cylinder device 4 which is the drive means of the first embodiment. Yes, other than that, the device can be configured exactly as in the first embodiment.

Also in this example, the same effect as that of the first embodiment can be obtained.

FIG. 6 (b) shows an example in which a geared motor 13 of the type in which a weight 14 is connected to the tip of a chain 15 is used. Since the weight of the vehicle to be placed and the weight can be balanced, there is an advantage that a motor having a relatively small output torque can be used.

Embodiment 3 In this embodiment shown in FIGS. 7 to 9, an upper lift pallet (first lift pallet) provided so as to move up and down from the above-ground parking space by a frame structure 31 constructed on the ground surface F is used. Lift pallet 32), a lower lift pallet (second lift pallet) 34 provided so as to move downward in an underground pit 33 excavated from the ground parking space, and a ground traverse pallet 35 traversing the ground surface. 1 shows a three-tiered multi-level parking device as a unit parking device. The subscripts attached to the reference numerals in these figures have the same meaning as in the first embodiment.

One end of the upper lift pallet 32 is fixedly connected to the frame structure 31, and the pallet side pulleys 221 ₁ ,
221 ₂ , 221 ₃ and fixed-side pulleys 221 ₁ , 222 ₂
The rope 36 is supported by an upper side rope 36 as a stamping member that is sequentially wound around the and so as to be able to move up and down, and the other end of the rope 36 is connected to a drive means such as a returning cylinder type hydraulic cylinder device 37 of this example. ing. The drive means will be described later. One end of the lower elevating pallet 34 is connected and fixed to the wall surface of the underground pit, and in the middle, similarly, the pallet side pulleys 223 ₁ , 223 ₂ , 223 ₃ and the fixed side pulleys 224 ₁ , 224. _It is supported so as to be able to move up and down by a lower rope 38 as a stamping member that is sequentially wound around ₂ and
The other end of the rope 38 is connected to the drive means.

Further, 40 is a locking device provided on each upper lifting pallet 32, and 41 is a locking device provided on each lower lifting pallet 34, both of which are hooks 402, 41 with respect to lock pins 401, 411.
When 2 is engaged, it is restrained so that it cannot move up and down, and when the engagement is released by the operation of an engagement release device such as a solenoid (not shown), it is allowed to move up and down.

The feature of the multi-story parking system of this example is that the upper rope 36 and the lower rope 38 are pulled in and out using one hydraulic cylinder device 37, and the upper lift pallet 32 and the lower lift pallet 34 are pulled out. This is because one of them is selected to move up and down, and this has the advantage that the number of drive devices such as motors can be reduced by one compared to the case where separate upper and lower lift drive mechanisms are provided. can get.

Explaining the structure of the drive means of this example composed of the hydraulic cylinder device 37 and the like, in the hydraulic cylinder device 37, the cylinder housing 371 is vertically arranged so that the piston rod 372 can be extended downward. At the same time, the cylinder housing 371 is allowed to move up and down by a guide means (not shown), and the upper end of the cylinder housing 371 is locked so that its lowering with the frame structure 1 can be restricted. A device 373 is provided. 374 is a hook, 3
Reference numeral 75 is a lock pin, and the hook 374 and the lock pin 375 are operated by the operation of an engagement releasing device such as a solenoid (not shown).
It is provided so as to allow the cylinder housing 371 to move up and down by releasing the engagement.

The other end of the upper rope 36 is
It is fixedly connected to the fixed portion via a pair of upper and lower fixed pulleys 42 and 43, and further via upper end pulleys 376 and 376 of the cylinder housing 371. By connecting the other end of the upper rope 36 in this manner, the engagement of the lock device 373 is released from the state shown in FIG. 7 (the state where the cylinder housing 371 is held at the upper limit position by the lock device 373). By lowering the cylinder housing 371, the upper rope 36 is unrolled, and any of the upper lifting pallets 32 can be lowered (see FIG. 9). To raise the lowered upper lift pallet 32, the cylinder housing 3 is moved from the state of FIG. 9 to the state of FIG.
The lock device 373 may be engaged after the upper rope 36 fed out by raising 71 is pulled in.
It goes without saying that any of the upper elevating pallets 32 to be moved up and down releases the engagement of the lock device 40 prior to the lifting.

The other end of the lower rope 38 is connected and fixed to the fixed portion via a pair of upper and lower fixed pulleys 44 and 45, and further via a lower end pulley 377 of the piston rod 372. By connecting the other end of the lower side rope 38 in this way, the lower side rope 38 is drawn in by moving the piston rod 372 upward and storing it in the cylinder housing 371 from the state shown in FIG. Any of the pallets 34 can be raised (see Figure 8). In order to lower the lifted lower lifting pallet 34, the lower rope 38 drawn by lowering the piston rod 372 from the state of FIG. 8 to the state of FIG.
Should be paid out. Needless to say, any one of the lower elevating pallets 34 to be moved up and down releases the engagement of the lock device 41 prior to lifting.

As described above, in the three-dimensional parking apparatus of this example, the upper rope 3 that is hung around the upper lift pallet 32 is used.
6 and the lower rope 3 to be hung around the lower lifting pallet 34
8 are provided separately, but these can be pulled in or out by a driving means composed of one hydraulic cylinder device 37 and the like, and the lifting pallet 3 at an arbitrary position can be provided.
Since 2, 2 and 34 can be moved to the above-ground parking space, there is an advantage that one driving device such as a motor can be further reduced as compared with the case where the upper and lower lifting mechanisms are separately provided.

In this example, as shown in the figure, the ground traverse pallet 35 is installed on the ground surface by one less than the number of adjacent unit parking spaces, and this is constructed so that it can traverse between adjacent devices. Therefore, there is also an advantage that each elevating pallet can be arbitrarily moved up and down.

Embodiment 4 The multi-story parking apparatus of this example shown in FIG. 10 has a structure in which one rope 50, which is a pulling member, is hung around the entire upper and lower pallet 32 and lower pallet 34. Is shown.

That is, the upper lifting pallet 32, the lower lifting pallet 34, and the lock device 40 attached to them.
41, the fixed-side pulleys 222, 224, and the pallet-side pulleys 221 and 223 all have the same configuration as that of the third embodiment, except that the rope 50 having one end connected to the fixed portion is fixed to the fixed-side pulley 222. , 224, the pallet side pulleys 221 and 223 are alternately wound around one another, and the other end is fixedly connected to the fixed portion via the tip pulley 513 of the piston rod 512 of the hydraulic cylinder device 51 installed on the frame structure 1. It is in. In addition, 53,5
Reference numerals 4 and 55 denote fixed portion side pulleys for hanging the rope from the lower side to the upper side, 56 denotes a turning pulley for turning the rope 50 guided upward from the pallet side pulley 221 ₁ at the end of the upper lifting pallet, 511 is a cylinder housing.

According to the structure of this example, the driving means of the three-stage multi-storey parking device can be composed of only one hydraulic cylinder device 51, and therefore, compared with the conventional device which requires a large number of lifting pallet driving devices. In addition to being extremely advantageous, Embodiment 3
Compared with, there is an advantage that the structure of the driving means can be simplified.

Embodiment 5 The multi-story parking apparatus of this example shown in FIG.
Compared with the upper lift pallet 32 and the lower lift pallet 34
Is common in that the rope 60, which is one pulling member, is wound around all of the above, and the difference is that
A motor 61 is used instead of the hydraulic cylinder device 51 which is a driving means, and the other end of the rope is connected and fixed to a fixing portion via a pulley 613 of a weight 612. 611 is a sprocket for pulling the rope 60.

According to the configuration of this example, as in the fourth embodiment, the driving means of the three-stage multi-level parking apparatus can be configured by only one motor 61, so that a large number of lifting pallet driving apparatuses are required. In addition to being extremely advantageous as compared with the conventional device, there is an advantage that the configuration of the driving means can be simplified as compared with the third embodiment. Further, since the weight 612 can be weight-balanced with the weight of the lifting pallet and the vehicle placed on the lifting pallet, there is an advantage that a motor having a relatively small output torque can be used.
