Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-stage multi-level parking apparatus, and more specifically, a drive means for moving an upper parking pedestal up and down between a middle position where a vehicle enters and leaves and an upper position above it.
And a drive means for moving the lower parking pedestal up and down between the middle position and the lower position therebelow by one driving mechanism.
The present invention relates to a multi-tiered parking system.

[0002]

2. Description of the Related Art A three-stage multi-storey parking system has been widely used to effectively use a parking area in a basement of a building or the like, and a three-stage multi-story parking system is located above a middle stage position which is aligned with a vehicle entrance / exit road surface. The upper and lower parking garages (hereinafter referred to as "pallets") are placed in the space and the pit-type lower space, and the upper and lower pallets are moved up and down to the middle tier as necessary to move in and out the vehicle. It was made possible.

[0003] In general, a plurality of three-stage type multi-level parking devices are provided in parallel, and even if the vehicle is located at any of the upper and lower tiers, it may be designed so that it can be moved in and out as needed. Many. For example, by installing one middle pallet (parking platform) at the middle tier, which is the loading / unloading surface, than the number of adjacent devices, and allowing these middle pallets to traverse between adjacent devices, A so-called middle pallet traverse type configuration is adopted in which the space at the middle tier required for raising and lowering the upper and lower pallets can be moved to any of the adjacent devices.

FIG. 12 shows an outline of a case where three rows of such three-dimensional type three-dimensional parking devices are arranged in parallel.
FIG. 4 is a diagram showing an example of a conventional specific structure of a three-stage multi-dimensional parking device.

The operation of the apparatus shown in FIG. 12 will be described when the vehicle is leaving the vehicle. First, the pallet 102c on which the vehicle is mounted is raised in the state shown in FIG. 12 (a), and then one less than the number of parallel parking apparatuses is provided. The intermediate pallets 10la and 10lb (the pallet on which the vehicle is mounted) are sequentially traversed at the intermediate positions shown in FIG. 12C to create an empty space without the intermediate pallet shown at the right end of FIG. 12B. Shift to. As a result, the upper pallet 102a can be lowered, and the vehicle can be unloaded by lowering the upper pallet 102a (see FIG. 12D).

FIG. 13 shows a conventional apparatus in which the ascending / descending of the upper pallet and the lower pallet are separately provided for the upper and lower pallets in each row. In this figure, 1
Reference numeral 01 is a middle pallet, 102 is an upper pallet, 103 is a lower pallet, 104 is a chain wheel for driving the upper pallet up and down, 105 is a chain, and one end 105a
Is attached to the upper pallet 102, is mounted on the chain wheel 104 in the middle, and the other end 105 b is attached to the upper pallet via the movable pulley 106. Reference numeral 114 denotes a chain wheel for driving the lower pallet up and down provided on a fixed portion, 115 denotes a chain mounted on the chain wheel 114, and 115 denotes a chain, one end of which is connected to the lower pallet 103, and the chain wheel is midway. It is mounted on 114, and the other end 115 b is attached to the weight 116. In addition, 117 is a fixed guide wheel 118, 1 so that the lower pallet 103 can be raised and lowered in a parallel posture.
It is a wire for maintaining the posture, which is laid between the front end and the rear end of the lower pallet 103 via 19 as shown in the figure.

With this structure, the upper and lower pallets can be raised and lowered separately.

By the way, the three-stage type three-dimensional parking apparatus can be constructed such that the upper pallet 102 and the lower pallet 103 are raised and lowered by separate motors or the like as described above. In this case, for example, the apparatus as shown in FIG. In the form of arranging them in parallel in a row, a total of 6 drive units of 2 × 3 are required, resulting in a high cost and a heavy maintenance burden. Therefore, there has been conventionally proposed a device for raising and lowering the upper and lower pallets by using as few driving devices as possible, for example, a technique for raising and lowering the upper and lower pallets by one common drive motor (Japanese Patent Laid-Open No. 3-304181). Issue)
There are also proposals for raising and lowering adjacent left and right lower pallets with a common single drive motor, and these proposed methods have the advantage that the number of drive devices for raising and lowering can be reduced compared to the number of pallets.

[0009]

In all of the above proposals for sharing the drive unit, the operation of raising and lowering the pallets is performed by selectively and sequentially moving some pallets as described with reference to FIG. Paying attention to the fact that as long as it can be done, it is possible to reduce the number of drive devices by sequentially moving two upper and lower or left and right pallets with a single drive device (motor). is there.

However, the former Japanese Patent Laid-Open No. 30418/1991
The mechanism of the multi-level parking device proposed in Japanese Patent Publication No. 1 has a fixed pulley and a movable pulley (assembled on the lower pallet) for raising and lowering the upper and lower pallets separately by one common motor, and one end of the chain is attached. While connecting to the upper pallet,
The other end is wound around a moving pulley and a fixed pulley and then connected to a free weight, and there is a weight in the free state, which may interfere with the surrounding mechanism due to shaking or the like. There is a problem in ensuring stable operation.

The latter mechanism can reduce the number of motors by half when the number of parallel vehicles is even, compared with the case where they are mounted on the upper and lower pallets of the parking device, but when the number is odd, for example, in FIG. When the number of units in parallel is 3, a total of 4 units are required, one for each of the upper and lower units, and the effect of sharing the device is only 1 / 1.5 at most, so efficiency is insufficient. Not only that, the standard for the common motor and the chain mechanism attached to it, and the standard for the motor for independently driving the remaining one unit and the standard for the chain mechanism attached to it are separately prepared and installed. However, it is not always efficient because the number of parts with different specifications increases. Especially practically, when applying this parallel three-tiered multi-level parking device to an underground parking lot of a building where the space between columns is often restricted by building standards etc. due to the strength of the beams, etc. In practice, there are many cases where a parallel number of 3 is adopted, and therefore the above-mentioned problem regarding the system in which the driving device is shared by the left and right pallets cannot be ignored.

The present invention has been made in order to solve such a problem, and the driving mechanism is shared between the upper and lower pallets to reduce the structural load of the driving device and the power supply wiring. In addition, it is an object of the present invention to provide a novel three-stage multi-level parking device that can reduce the work load of maintenance and inspection.

Another object of the present invention is to provide a novel three-stage multi-story parking system which does not have the problem as proposed by the above-mentioned Japanese Patent Laid-Open No. 3-304181 when one elevator driving mechanism is commonly used for the upper and lower pallets. It is in the area of providing equipment.

[0014]

The feature of the three-stage type multi-level parking device of the present invention that achieves the above-mentioned object is that it is provided so as to be able to move up and down between the upper-stage position and the middle-stage position where a vehicle exits or enters the vehicle. A three-tiered multi-level parking apparatus including an upper pallet (parking platform) and a lower pallet that is vertically movable between lower pallets, and includes a vertical movement range of the upper pallet and the lower pallet. A drive chain extending endlessly rotatable in the direction for pallet lifting, one drive means for rotating the drive chain forward and reverse, and a part of the drive chain provided so as to be engageable with the upper pallet. At the same time, the upper pallet lifting and lowering bra that supports the upper pallet by the engagement and raises it from the middle position to the upper position by the forward rotation of the drive chain and lowers it from the upper position to the middle position by the reverse rotation. And a part of the drive chain engageable with the lower pallet, and the engagement supports the lower pallet to raise the drive chain in the reverse direction from the lower position to the middle position and forward rotation. The lower pallet lifting bracket that lowers from the middle position to the lower position and the forward / reverse rotation of this drive chain can be performed within a predetermined range for raising and lowering each of the upper parking platform and the lower parking platform separately. Chain drive control means for controlling the drive means, lock means for restraining and supporting the upper pallet so that it cannot be lowered at the upper stage position, and restraining / releasing of the lock means in synchronization with lifting and lowering of the upper parking platform. And a lock control means.

The drive chain and the like are preferably provided on the rear side of the pallet opposite to the vehicle loading / unloading side.

Needless to say, in addition to the above structure, a mechanism such as the wire for maintaining the pallet posture described above may be provided if necessary.

In the above structure, the upper pallet lifting bracket and the lower pallet lifting bracket may be provided separately, or one bracket assembled to the chain may serve as both of them. You can also

The structure of the multi-level parking device of the present invention can be used as a single unit, but a plurality of devices can be used in parallel. In the case of this parallel structure, the above-mentioned conventional middle pallet traverse type is used. A mechanism is also provided.

That is, according to the present invention, a plurality of the above-mentioned three-stage type three-dimensional parking devices are arranged adjacent to each other in parallel and an intermediate pallet is arranged at the middle position of the parallel parking devices by one less than the number of the parallel parking devices, and these pallets are arranged. Another feature is that the middle pallet is provided so as to be traversable between the middle tiers of adjacent parking devices so that an empty middle tier without a pallet can be transferred to an arbitrary parking device. A motor (electric motor), a hydraulic cylinder device (preferably a double-acting type), or the like is used as the driving means.

[0020]

According to the present invention having the above-mentioned structure, the upper pallet is moved up and down or the lower pallet is moved up and down by rotating one chain mounted on the endlessly rotating drive chain wheel in the forward or reverse direction. Since the descending can be selected and performed, the efficiency of sharing the driving means is halved as compared with the conventional device in which the driving means are provided separately on the upper and lower sides.

It is mounted so as to project, and this bracket 506 is shown in FIG.
As shown in (b), the pallet (2, 3) is raised from its lower side to engage with the lower surface. In addition, 201 and 301 are small-diameter through holes provided so that only the drive chain 503 can be inserted up and down. The drive chain 503 can be inserted, but the insertion of the bracket 506 is prevented, so that the pallet ( 2, 3) The weight of the pallet can be supported by the engagement with the lower surface.

Further, as shown in FIGS. 1 and 2, the lower pallet 3 includes the above-mentioned bracket 506 together with the drive chain 503.
A large-diameter through hole 302 that allows the insertion of the small-diameter through-hole 301 is provided so that the bracket 506 engages with the lower surface of the peripheral edge portion of the small-diameter through hole 301 of the upper pallet 3 (FIG. 1).
And the state of being engaged with the lower surface of the peripheral edge portion of the small-diameter through hole 201 of the lower pallet 2 (FIG. 2).
It can be switched by rotation of 3.

As shown in FIG. 5, the upper fixed position locking device of the sixth step 6 is formed as a pair of left and right hook devices on the frame 504, and the hook 602 is locked by an electromagnetic actuating device 601 operated by a control device (not shown). The upper pallet 2 is rocked so that the bracket 202 provided on the upper pallet 2 is engaged so as to be picked up and locked so that the upper pallet 2 cannot be lowered, and similarly, the lock is released by the hook removal control of the electromagnetic actuator 601. It is provided to allow the lower pallet 2 to descend. In addition to the structure shown in FIG. 5, the hook of the upper fixed position locking device 6 has a structure in which a hook 603 provided on the upper pallet 2 side is fixed to a bracket 604 fixed to the frame 501 side as shown in FIGS. The lower surface of the upper pallet 2 may be engaged and supported by a hook 605 of a hook device provided on the frame 504 as shown in FIG.

FIGS. 6 and 7 show a wire mechanism for lowering and raising the upper pallet 2 or the lower pallet 3 while maintaining the horizontal posture thereof. FIG.

1, 902, 903, and 904 are provided between the front portion and the rear portion of the upper pallet 2 in such a manner that a pair of left and right wires 905 are stretched as shown in the figure, and the movements of the left and right wires are synchronized by the equalizing shaft 906. It is the one. The lower pallet 3 can be lowered and raised while maintaining the horizontal posture of the lower pallet 3 in substantially the same manner except that the wire tensioning method is different as shown in FIG. ing.

Next, the operation of the three-stage type multi-level parking device configured as described above will be described.

Now, assume that the apparatus is in the state shown in FIG. That is, the upper pallet 2 is lifted to the upper position and locked by the upper fixed position locking device 6 so that it cannot be lowered from that position, the middle pallet 1 is located at the middle position, and the lower pallet 3 is located at the lower position. Is located on the pedestal 8 in a bottomed state. The drive chain 503 is
The bracket 506 is attached to the small-diameter through hole 201 of the upper pallet 2.
It is stopped by engaging with the lower surface of the peripheral edge of the.

In this state, first, the middle pallet 1 is moved from the middle position of the device to an adjacent parking device by a traverse driving means (not shown) to make the middle position an empty space.

Next, the upper sprocket 501 is rotated counterclockwise in FIG. 1 while unlocking the upper fixed position locking device 6, and the upper pallet 2 is attached to the bracket 506.
It is lowered while being supported by and lowered to the middle position and stopped (see FIG. 1B). As a result, the upper pallet 2 is on the floor 7
The vehicle can be put in and out according to.

In order to return the upper pallet 2 to the upper position, the drive chain 503 is rotated in the clockwise direction in FIG. 1 to raise the upper pallet 2 to the upper position while being supported by the bracket 506. It suffices to apply the lock by the stop device 6, and thereby the state of FIG. 1A is restored.

Locking by the upper fixed position locking device 6 /
Control of unlocking and normal / reverse rotation of the drive chain 503 is performed by operating the electromagnetic actuator 601 and controlling the rotation driving of the motor 505 by a controller (not shown).

Next, the case of raising and lowering the lower pallet 3 will be described. From the state of FIG.
3 is rotated counterclockwise in FIG.
After moving the bracket 506 attached to No. 03 into the large-diameter through hole 302 of the lower pallet 3, the bracket is further rotated by 180 ° to be engaged with the lower surface of the peripheral edge of the small-diameter through hole 301. (See FIG. 2 (a)). If there is a middle pallet at the middle position, at the same time or subsequently thereto, the transverse drive means moves the middle position of the device to the adjacent parking device to make the middle position an empty space. In this state, the drive chain 503 is further rotated counterclockwise to raise and stop the lower pallet 3 to the middle position while being supported by the bracket 506 (see FIG. 2B). As a result, the lower pallet 3 is aligned with the floor 7 and the vehicle can enter and leave.

In order to return the lower pallet 3 to the lower position, it is sufficient to rotate the drive chain 503 in the clockwise direction in the drawing and lower it to the lower position while supporting it with the bracket 506. Return to the state of.

As described above, according to the three-dimensional parking apparatus of this embodiment, the upper pallet 2 and the lower pallet 2 are controlled by controlling the forward / reverse rotation of the drive chain 503 and the lock / unlock of the upper fixed position locking device 6. The pallet 3 can be controlled to move up and down, and further, the drive chain for moving up and down can be constructed very simply by the endless rotation type structure, and the chain 503 can be rotated only in a predetermined endless track. Since this is a formula, there is no possibility of interference with surrounding devices and members, and there is an advantage that stable and safe operation of the device can be easily ensured.

The bracket 506 having the above structure is used.
Although one is commonly used for the upper and lower pallets, it may be provided separately. In such a case, the engagement between the upper pallet 2 and the lower pallet 3 is changed. Has the advantage of being faster. Further, in the configuration of FIGS. 1 and 2, in order to change the engagement between the bracket 506 and the upper and lower pallets 2 and 3, the through hole through which the drive chain 503 is inserted is a small diameter through hole provided in the upper pallet. 201, the small-diameter through-hole 301 and the large-diameter through-hole 302 provided in the lower pallet are given, but the present invention is not limited to this. For example, the lower-stage pallet is provided with a short flange having only the small-diameter through-hole and has a large diameter. The through hole may be formed so as not to be a hole, as long as the state in which the bracket 506 can be engaged with the upper and lower pallets from the lower side surface can be transferred by forward and reverse rotation of the drive chain. is there.

Embodiment 2 In this embodiment shown in FIG. 8, similarly to that shown in FIG. 3, a drive chain 513 extending vertically and endlessly rotatable with upper and lower sprockets 511 and 512 is provided on the left and right sides of the pallet. An upper sprocket 511, 511 provided in a pair to drive the left and right drive chains 513 is provided on the frame 504. One motor 515 and link chains 516, 51
6 is used for rotation, and other configurations are the same as those described in the examples of FIGS. 1 to 7 above. 8A shows a state where the upper pallet 2 is lowered to the middle position, and FIG. 8B shows a state where the lower pallet 3 is raised to the middle position. In the drawings, the bracket 506 attached to the drive chain shows the engaged state with the pallet at the actual position (middle position) shown by the solid line in black, and the phantom shown by the broken line in white. It shows a state of being engaged with the pallet at the upper moving position.

According to the structure of this embodiment, the pallet is lifted up and down while supporting the load at its left and right positions, so that there is an advantage that a more reliable and safe operation can be secured. A means for synchronizing the operations of the left and right drive chains 503 can be provided as needed.

Embodiment 3 This example shown in FIG. 9 shows an example in which the left and right upper sprockets 511 and 511 in the example of FIG. 8 are synchronously rotated by a synchronous shaft 518 that is axially rotated by a reduction gear 517. By doing so, it is not necessary to provide any other means for synchronizing the left and right drive chains. 519 is a motor.

The present invention is not limited to the above embodiment, and can be implemented in various modified modes without departing from the scope of the invention.

For example, as in the structure shown in FIGS. 10 and 11, the rotation orbits of the drive chains may be aligned with or perpendicular to the front and rear direction of the pallet, or one motor may drive one drive chain. The rotation may be forward or reverse, or the pair of left and right drive chains may be rotated. When rotating the pair of left and right drive chains with one motor, it is of course possible to attach a pair of synchronizing means for the pair of drive chains.
