Description

[Detailed description of the invention] (Industrial application field) The present invention is a multi-stage parking system that has multiple parking compartments in the vertical direction and allows vehicle holders to be accommodated in each parking compartment in a manner that allows them to be freely inserted and removed. The present invention relates to an automatic parking device, and more particularly to a safety device when a vehicle cradle is moved in the vertical direction in such a parking device.

(Prior art) In recent years, especially in urban areas, parking devices with a circulation of vehicle pedestals called parking towers have become popular. are supported at a predetermined distance from each other by endless chains wrapped between a pair of upper and lower chain wheels, and when a specified vehicle cradle is called, the endless chain is moved according to the position of the vehicle cradle. This is done by running it for a predetermined length.

However, although this conventional vehicle cradle circulation type parking device has the effect of accommodating many vehicles in a relatively small space, when calling one specified vehicle cradle to the vehicle loading/unloading section, it is difficult to When the chain is running, all other unnecessary vehicle rests are also circulated, which requires a large-output power device to drive the endless chain, and wastes power. There was a problem. Particularly when vehicles are placed on each vehicle pedestal, the total weight of the vehicles becomes large and the wasted power also increases.

The present applicant has already proposed a multi-stage automatic parking system as shown in FIG.
No. 133007). The multi-stage automatic parking device shown in FIG. 7 guides an elevating bed 111 (composed of a pair of left and right rails 113) on which a vehicle cradle 122 can be placed in a removable manner in the vertical direction, and also guides the vehicle in and out. A lifting shaft 101 having a section X, and the lifting shaft 1
It is equipped with a plurality of parking rooms 102A, 102B, etc. arranged in parallel in the vertical direction before and after the elevator shaft 101, and the elevator shaft 101 is provided with an elevator drive device 103 for raising and lowering the elevator bed 111 in the vertical direction. , Furthermore, in each of the parking rooms 102A, 102B..., there is a fixed bed 121 to which an elevating bed 111 that moves up and down in the elevating shaft 101 can be selectively connected.
and the fixed bed 121 on the fixed bed 121.
Vehicle cradle 12 that can be moved horizontally guided by
2, and the vehicle cradle 122 is attached to the fixed bed 121.
and a pedestal transfer device 104 for reloadably moving between the elevating bed 111 connected to the fixed bed 121.
03, each of the parking rooms 102A, 102B...
Fixed bed 1 in one of the designated parking spaces.
21 and stopped there, then the vehicle pedestal 122 on the fixed bed 121 is transferred onto the elevating bed 111 by the pedestal transfer device 104 of the parking room, and then A series of vehicle cradle calling operations, including moving the elevating bed 111 on which the vehicle cradle 122 is placed to the vehicle loading/unloading section X and stopping there; and The vehicle cradle 122 is placed in the reverse order to the above order.
The control panel 11 performs a series of vehicle cradle sending back operations until the vehicle is returned to its original parking room without the vehicle.
I am trying to have it done automatically by starting from 0.

The lifting drive device 103 is equipped with a motor 14 that can rotate forward and backward, and a suspension chain 115 that suspends and supports the lifting bed 111. They are installed at two locations in the front and rear directions (vehicle forward and backward directions). In addition, in the parking device of this previously applied application, one lifting drive device 103 supports either the front or rear left and right sides of the vehicle cradle 122, and there are a total of two lifting drive devices 103,
103 supports the four corners of the vehicle cradle 122.

In the parking device of this application, a relatively small output device can be used as the cradle transfer device 104 for moving the vehicle cradle 122, and only the necessary vehicle cradle 122 can be moved. This has the advantage of eliminating wasted power.

However, in the previously applied parking device shown in FIG. 7, when the elevator bed 111 is moved up and down in the elevator shaft 101, if one of the two elevator drive devices 103 at the front and rear is out of order, When only the other elevating drive device 103 is activated, or when a part of the elevating bed 111 gets caught in the guide (pillar of the elevating shaft portion) 107 for some reason when elevating the elevating bed 111,
It is expected that the elevating bed 111 will be inclined significantly, and in that case, the vehicle cradle 122 on the elevating bed 111 and the vehicle A placed on it will
There is also the possibility that it will tilt significantly, creating a dangerous situation.
Moreover, the elevator shaft 1 remains tilted with the elevator bed 111.
If the interior is moved up and down, when inserting or removing the vehicle,
When the elevating bed 111 is stopped at a predetermined floor, there will be a difference in level between the elevating bed 111 and the fixed bed 121 on either the left or right side, making it difficult to transfer the vehicle cradle 122 smoothly. It will be done.

The edges 8a, 8b of the left and right double walls 8, 8 in the front-rear direction (arrow A-B direction) are guides (columns) located at each end (four corners) in the front-rear direction of the elevator shaft 1. 7, 7... are installed on the inner surface so as to face each other closely with an appropriate small interval (for example, about 1 cm) between them. These double walls 8, 8, if for some reason the elevating bed 11 inclines by a slight angle (for example, about 0.5 degree) in the front-rear direction, the downwardly inclined side end 8a of the double wall 8 When the upper end comes into contact with the inner surface of the guide 7, and as shown in FIG. Guide 7 at the top of
The both side plates 81, 81 are connected to the third side between the end edge 8a in contact with the support 19 at a position closer to the edge 8a.
As shown by chain lines 81' and 81' in the figure, they are bent outward from each other. Incidentally, when the side plates 81, 81 are bent outward from each other in this way, the distance between the side plates 81, 81 becomes larger than the current distance M (the distance indicated by the symbol N in FIG. 3).

The operation switch S is connected to each side plate 81 at the top of each double wall 8, 8 near both ends in the front and back direction.
They are installed in 81 rooms (4 in total).
These operation switches S, S... are connected to the above-mentioned both side plates 8
It is fixed to the inner surface of one of the side plates 1 and 81, and the distance between both side plates 81 and 81 is larger than a predetermined distance (for example, the distance indicated by the symbol N in FIG. 3).
When the temperature drops, the power supply to the motor 14 of the lifting drive device 3 is cut off. That is, this operation switch S is provided with a switch operation piece 92 that can freely rotate in an arc in the front and rear directions with respect to the switch body 91, and further has a hole 93 at the tip of the switch operation piece 92.
An operation piece operation member 94 such as a flexible wire is inserted into the hole 93, and both ends 94a, 94a of the operation piece operation member (wire) 94 are inserted in the switch opening direction of the switch operation piece 92 ( In FIG. 3, they are fixed to the respective side plates 81, 81 in a tensioned state and directed obliquely outward in the direction of arrow A). And this operation switch S
is open when the distance between the two side plates 81, 81 is normal (the distance M in FIG. 3), allowing the motor 14 to be energized, but if for some reason When the bed 11 tilts in the front-rear direction to an angle α (FIG. 4) that exceeds the allowable range, one end edge 8a (or 8b) of the double wall 8 abuts against the inner surface of the guide 7, as described above. Both side plates 81, 81 are deformed to widen the gap between the side plates 81, 81, and at this time, each end 94a, 94b of the operating piece operating member 94 is
As a result, the switch operation piece 92 is tilted in the switch opening direction with respect to the switch body 91 as shown by the chain line 92' in the figure. When any one of the four operation switches 92 is operated in the switch opening direction, the operated operation switch S is switched from the closed side to the open side, and the above-mentioned 2 operation switches S are switched from the closed side to the open side. Each motor 14, 14 of the base lifting drive device 3, 3
At the same time, power to both is cut off. In the illustrated embodiment, each end portion 94a, 94b of the operating piece operating member (wire) 94 extends outside the side plate through holes 83, 83 formed in the side plate 81, 81, and a single (one) An operating piece operating member 94 spans between each of the switch operating pieces 92 of the two front and rear operating switches S, S in the double wall 8. The operating piece operating member 94 is bent at a portion through which the hole 83 of the side plate 81 is inserted, and is fixed by its frictional force.

The safety device of the embodiment shown in FIGS. 1 to 4 has the following effects. That is, when the elevator bed 11 moves vertically within the elevator shaft 1, if for some reason, for example, one of the two elevator drive devices 3 at the front and rear malfunctions, the other elevator drive device 3 When the lift bed 11 is activated, or when a part of the lift bed 11 gets caught on the guide 7 for some reason while going up and down, it is expected that the lift bed 11 will tilt significantly in the front-back direction. However, even if the elevating bed 11 attempts to incline beyond the permissible angle range, the end of the double wall 8 will not touch the guide 7 when the elevating bed 11 inclines to a predetermined angle within the safe range (for example, about 0.5 degrees). contact,
When the elevating bed 11 further tilts from this state, each side plate 8 of the double wall end that contacts the guide 7
1, 81 is widened so that the operating switch S located there is actuated to immediately and simultaneously stop both motors 14, 14 of each lifting drive 3, 3. Therefore, the elevating and lowering operation of the elevating bed 11 is also immediately stopped, and the elevating bed 11 is prevented from being tilted beyond an angle range that is permissible from a safety point of view. Also, like this, the elevating bed 1
If the vertical movement of the vertical bed 11 is stopped when the vertical bed 1 is tilted within a predetermined angle range,
As in the case of the multi-stage automatic parking system (FIG. 7) according to the applicant's previous application, if you drive without noticing that the elevating bed 11 is tilted, and when transferring the vehicle cradle 22, the elevating bed This prevents the trouble of being carried out in a state where there is a large step difference between the fixing bed 11 and the fixed bed 21. Incidentally, when the lifting bed 11 is forced to stop midway in the lifting shaft 1 due to the lifting bed 11 being tilted, if the cause of the lifting bed 11 is tilted is found and corrected, the lifting drive device 3,
3 can be canceled.

FIG. 5 shows a safety device according to another embodiment of the present invention. In the embodiment shown in FIG.
85, and an operation switch (limit switch) S is installed at the tip of each of the pillars 85, 85.
It is installed so as to correspond closely to the inner surface of the guide 7 of the elevator shaft 1. In this embodiment, when the elevating bed 11 is tilted to a predetermined angle in the front-rear direction for some reason, the operating switch S at the tip of the support column 85 contacts the guide 7 and the elevating drive device is immediately activated. The power supply to the motor (not shown) is stopped.

FIG. 6 shows a safety device according to yet another embodiment of the present invention. The safety devices of the two embodiments shown in FIGS. 1 to 4 and FIG. For,
The safety device shown in FIG. 6 is such that when the lifting bed 11 is tilted in the left-right direction (in the direction of arrow C-D), the operating switch S is operated to stop the power supply to the motor of the lifting drive device. There is. That is,
In the embodiment shown in FIG.
Supports 77, 77 are respectively erected at positions corresponding to the guides (side guides) 7, located at the middle part in the front and back direction, and the tips of the respective supports 77, 77 are arranged close to the inner surface of the guide 7. An operation switch (limit switch) S is installed in this way.

In yet another embodiment, the operation switch S is operated for a single elevating bed 11 when the elevating bed 11 is tilted in the front-rear direction as shown in FIGS. 1 to 4 or 5. It is also possible to use a type in which the operating switch S is operated when the elevating bed 11 is tilted in the left-right direction as shown in FIG. 6. In this case, the operation of the elevating drive device can be reliably stopped immediately regardless of whether the elevating bed is tilted forward or backward or to the left or right.

(Effect of the invention) The safety device of the multi-stage automatic parking device of the present invention is such that when the elevator bed 11 is tilted to a predetermined angle range, the operation switch S is operated, and the operation switch S activates the elevator drive device 3. Therefore, even if the elevating bed 11 is tilted for some reason while the elevating bed is being raised or lowered, the elevating bed 11 is prevented from being tilted significantly (tilting to a dangerous extent). This has the effect of being able to prevent this from happening.

Furthermore, according to the present invention, even if the elevating bed is tilted for some reason, as in the parking device shown in FIG. In other words, even if the elevating bed stops at a predetermined floor, there will be a step between the elevating bed and the fixed bed, and the vehicle cradle may collide with the other bed when changing the vehicle cradle. Or, the operation will not continue while there is a problem such as receiving an impact due to a difference in level, and if the elevating bed is tilted, the operation will be stopped immediately, and the user will not be informed that an abnormality has occurred. There is also the effect that it can be done.
