Description

  The present invention provides a three-dimensional structure for preventing a lift device from being submerged even if flooding occurs due to heavy rain or flooding in a building in an elevator type three-dimensional parking device that parks vehicles in a multi-tiered manner in a vertical direction in a building. The present invention relates to a lift flooding prevention method and apparatus for a parking apparatus.

  An elevator type three-dimensional parking apparatus is known as one of the facilities for efficiently parking a vehicle on a limited site. As one example of such an elevator type three-dimensional parking apparatus, there is a type in which a vehicle to be stored is placed on a pallet and then transported together with the pallet, as schematically shown in FIG.

  That is, the elevator type three-dimensional parking apparatus shown in FIG. 3 has a lift lifting / lowering unit (at the center part of the building 1 erected on the ground, leading to a loading / unloading port 2 provided on the front surface of the center part of the first floor part where the vehicle enters. A hoistway 3) is formed in the vertical direction. A storage space 4 is formed at a position between the left and right sides of the lift elevating unit 3 in the building 1. The left and right storage spaces 4 have a longitudinal direction of a pallet 6 for mounting a vehicle 5. (Fore-and-aft direction) The shelves 7 whose both ends can be supported via the lateral feed device 10 are provided in multiple layers in the vertical direction at a required arrangement pitch. Further, a lift device (lift cage) 9 provided with a lateral feed device 10 is arranged in the lift elevating unit 3 and is installed on a support base 8 at the top in the building 1. 12 is supported by being suspended. Thereby, the said lifting apparatus 9 is made to raise / lower the lift raising / lowering part 3 by winding up and down the wire rope 12 with this winding apparatus. In order to suspend the lift device 9 until the upper surface of the pallet 6 set on the lift device 9 is arranged at the same level as the loading / unloading port 2 at the bottom of the lift elevating unit 3. The pit 13 is provided. Reference numeral 14 denotes a steel frame of the building 1.

  When the vehicle 5 is stored using the elevator type multi-story parking device having the above-described configuration, the empty pallet 6 taken out from the shelf 7 at the required stage is set on the lift device 9 in advance in the pit 13. Make sure to hang it down. Next, the vehicle 5 to be parked is mounted on the pallet 6 on the lift device 9 from the central entrance / exit 2. Next, the lift device 9 is lifted by the hoisting device 11, and the actual vehicle pallet 6 is raised until it corresponds to the height position of the planned parking shelf 7. Thereafter, the vehicle 5 is traversed together with the pallet 6 by the lateral feed device 10 of the lift device 9 and stored in the shelf 7 (see, for example, Patent Document 1).

  On the other hand, when leaving the parked vehicle 5, the operation procedure reverse to that in the case of warehousing may be performed. That is, first, the hoisting device 11 raises and lowers the lift device 9 so as to correspond to the height position of the required shelf 7 in which the actual vehicle pallet 6 on which the vehicle 5 to be delivered is placed is placed. . Next, the actual vehicle pallet 6 of the unloading target vehicle 5 stored in the shelf 7 is traversed by the lateral feed device 10 of the lift device 9 and mounted on the lift device 9. Next, the lifting device 9 is suspended in the pit 13 by the hoisting device 11, and then the vehicle 5 is moved from the pallet 6 on the lifting device 9 to the outside through the loading / unloading port 2. That's fine.

  When the delivery operation of the vehicle 5 is completed, an empty pallet 6 remains on the lift device 9. If this empty pallet 6 is kept waiting at the position of the loading / unloading port 2, when the next work is a warehousing work of the vehicle 5, the warehousing work can be started quickly. In general, after the exiting operation is finished, the lift device 9 on which the empty pallet 6 is set is made to stand by while being suspended in the pit 13.

  The entrance / exit port 2 in the elevator type three-dimensional parking apparatus as described above is usually equipped with an entry / exit door (not shown), for example, during the lifting / lowering operation of the lift device 9 or during standby without carrying out the entry / exit operation. When the vehicle 5 is loaded on the pallet 6 through the loading / unloading port 2 or when it is loaded from the pallet 6 to the outside, the loading / unloading port 2 is closed by the loading / unloading door, and the interior of the building 1 is unmanned. It is common to let them be In the elevator type multi-story parking apparatus as described above, some water may enter the building 1 when the vehicle 5 is loaded and unloaded in the rain. For this reason, normally, the water that has entered the building 1 is collected in a drainage chamber (drainage mass) (not shown) provided at a required location of the pit 13 and is discharged to the outside using a required drainage device such as a drainage pump. It is like that.

  By the way, in recent years, as a device for enabling a plurality of parking spaces to be secured using the underground, a multistage three-dimensional parking device of an underground pit lifting type has come to be used frequently.

  Such an underground pit elevating type three-dimensional parking apparatus forms a pit 15 in the basement as shown in an outline of an example in FIG. 4, and stands a column 16 on the bottom surface of the underground pit 15. In addition, the parking pallets 17 are arranged in a plurality of stages in the vertical direction, for example, two stages in the vertical direction, and the parking pallets 17 are integrally connected by pallet columns 18 extending in the vertical direction to form a vehicle loading structure 19. The vehicle loading structure 19 is supported so as to be displaced (movable) in the vertical direction along the support column 16 and further includes a required lifting drive device 20 for driving the vehicle loading structure 19 up and down. As a configuration. As a result, usually, the vehicle loading structure 19 is lowered so as to be accommodated in the underground pit 15, and the upper parking pallet 17 is placed at the same level as the ground. The vehicle 21 can be moved in and out of the parking pallet 17. Further, by operating the lifting drive device 20 to raise the vehicle loading structure 19 along the support column 16, the lower parking pallet 17 is placed at the same level as the ground, The entry / exit operation of the vehicle 21 with respect to the lower parking pallet 17 can be performed.

  In the underground pit lifting and lowering type parking device as described above, there is a concern that the lifting drive device 20 may stop functioning when rainwater or the like flows into the underground pit 15 and the lifting drive device 20 is submerged. Therefore, as shown in FIG. 5, in a three-dimensional parking apparatus similar to that shown in FIG. 4, an elevating drive device 20 that raises and lowers the vehicle loading structure 19 is supported by an upper parking pallet 17. When there is a concern that rainwater or the like may flow into the pit 15 (see FIG. 4) and the electrical system of the lift drive device 20 may be submerged, the lift drive device 20 is operated by an operation panel (not shown) to load the vehicle. The structural body 19 is raised to a position at which the vehicle 21 (see FIG. 4) can be moved into and out of the lower parking pallet 17. Accordingly, it has been proposed that the lifting drive device 20 is raised together with the upper parking pallet 17 to a position higher than the ground to prevent flooding of the lifting drive device 20 (for example, Patent Documents). 2).

  Similarly to the above, a vehicle loading structure (vehicle elevating device) in which a plurality of vertical parking pallets are connected in the underground pit by pallet columns extending in the vertical direction so that the vehicle can be stored in multiple stages. ) Can be moved up and down, if there is a large amount of water in the underground pit due to heavy rain or the like, there is a risk of a submergence accident of the vehicle stored in the underground part. Concerned. Therefore, as shown in FIG. 6, an abnormality detector 22 is provided in the underground pit 15 for detecting a position where the level of water infiltration is a required amount above the floor of the pit 15 as an abnormal level. When the anomaly detector 22 detects the inundation level in the underground pit 15, the vehicle loading structure (vehicle elevating device) 19 is automatically raised until the lowermost vehicle 21 is placed on the ground. It has been conventionally considered (see, for example, Patent Document 3). In FIG. 6, those corresponding to those shown in FIG.

Japanese Patent No. 3239198 JP 7-18990 A JP-A-10-219711

  However, the drainage device for draining the pit 13 in the conventional elevator type multi-story parking device as shown in FIG. 3 is compared to the extent that it enters the building 1 when the vehicle enters and leaves in rainy weather. Since the drainage capacity is set on the premise of the entry of a small amount of water, a large amount of inundation occurs in the building 1 due to heavy rain such as torrential rain or the occurrence of floods, and a large amount of rainwater enters the pit 13 When this happens, there is a risk that the drainage by the drainage device will not be in time and water will accumulate in the pit 13.

  In this way, when water is accumulated in the pit 13, when the lifting device 9 is suspended in the pit 13 as the loading / unloading operation proceeds, the lifting device 9 is submerged, As a result, there is a concern that the electrical equipment attached to the lift device 9 such as the transverse feed device 10 may be submerged and adversely affected.

  Further, in the above-described conventional elevator type multi-story parking device, the lift device 9 in which the empty pallet 6 is set is made to stand by in a state where it is suspended in the pit 13 after the exiting operation of the parked vehicle 5 is completed. Therefore, if a large amount of water is immersed in the pit 13 during this standby state, the lift device 9 may be immediately submerged.

  In addition, what was described in the said FIG. 5 is for aiming at the flood prevention of the raising / lowering drive apparatus 20 for raising / lowering the structure 19 for vehicle loading in a three-dimensional parking apparatus of an underground pit raising / lowering type, FIG. It cannot be directly applied to the flood prevention measures of the lift device 9 in the elevator type three-dimensional parking apparatus as shown in FIG.

  In addition, in the case described in FIG. 5, when there is a concern that rainwater or the like may flow into the underground pit 15 (see FIG. 4) and the electric system of the lifting drive unit 20 may be submerged, the lifting / lowering is performed. The drive device 20 is operated, but at this time, no means for detecting the amount of rainwater or the like accumulated in the underground pit 15 is shown, and the operation of the lifting drive device 20 is as follows. Since only the idea of performing the operation via the operation panel is shown, the elevating drive device 20 can be automatically operated according to the water level in the underground pit 15. is not. On the other hand, as described above, in the elevator type three-dimensional parking apparatus as shown in FIG. 3, in general, entry / exit is performed except when the vehicle 5 is entered / exited with the lift device 9 suspended in the pit 13. Since the entrance 2 is closed by the entry / exit door and the interior of the building 1 is unmanned, the operator can check the water level in the pit 13 or directly operate the lift device 9 according to the water level. It is difficult.

  In the example shown in FIG. 6, an abnormality detector 22 is provided in the underground pit 15 to detect a position where the inundation level is a required amount above the floor of the pit 15 as an abnormal level. Since the idea of automatically raising the vehicle loading structure (vehicle lifting device) 19 based on the detection signal of the inundation level in the underground pit 15 is described, in view of this idea, FIG. In the three-dimensional parking apparatus of the elevator system as shown, an abnormality detector is provided for detecting a position where the inundation level is a required amount above the floor surface of the pit 13 as an abnormal level. It is conceivable to take measures to prevent flooding of the lift device 9 in the pit 13 by automatically raising the lift device 9 based on the detection signal of the inundation level. However, even if such measures are taken, when the lift device 9 on which an empty pallet 6 is set is suspended in the pit 13 after the vehicle 5 is left, the heavy rains will occur. When the building 1 is inundated due to heavy rain such as the occurrence of floods, etc., and a large amount of rainwater or the like suddenly enters the pit 13, the inundation in the pit 13 is detected by the abnormality detector. Since the water level in the pit 13 rises earlier than trying to raise the lift device 9 from the top, there is a possibility that the lift device 9 will not be able to retreat upward, so that the lift device 9 may be flooded. Can not be solved reliably.

  Therefore, the present invention is an elevator type multi-story parking device that reliably prevents flooding of the lift device even in the event of heavy flooding such as torrential rain or flooding, and suddenly a large amount of water floods the pit in the building. An object of the present invention is to provide a method and apparatus for preventing a flooding of a lift device of a multilevel parking device.

  In order to solve the above-described problems, the present invention provides a building with a vertical lift lift unit that leads to the entrance and exit, stores the lift device so that it can be driven up and down, and serves as a lower end of the lift lift unit. By providing a pit at the bottom of the indoor and lowering the lift device into the pit, the vehicle can be loaded and unloaded between the loading / unloading port and the upper side of the lift device. The above-mentioned lift device in the multi-story parking device that can be used for entering / exiting using the device is made to wait at the upper floor position on the second floor or higher during standby when no entering / exiting operation is performed, and the pit When there is a possibility that water has accumulated in the interior, a lift flooding prevention method for a multi-story parking device that stops the descent of the lift device to the pit to prevent flooding, and a building Inside, a lift lift part in the vertical direction leading to the entrance / exit is provided, the lift device is accommodated so that it can be lifted up and down, and a pit is provided at the bottom of the building which is the lower end of the lift lift part, and the above is entered into the pit By lowering the lift device, the vehicle can be loaded and unloaded between the loading / unloading port and the upper side of the lifting device, and the loading / unloading operation can be performed using the lifting device. In addition, a drainage mass is provided in the pit of the three-dimensional parking apparatus, and a water immersion sensor is provided for detecting a rise in the water level in the drainage mass. Further, based on the signal of the water immersion sensor, the lift device It is set as the lift flood prevention apparatus of the multilevel parking apparatus which has the structure provided with the controller which controls raising / lowering.

  Further, in the above, a method for determining whether or not there is a possibility that water has accumulated in the pit based on whether or not an increase in the water level in the drainage mass provided at the bottom of the pit is detected. And

  In the above configuration, when the controller is in a standby state where entry / exit work is not being performed, the lift device is placed on the upper floor of the second floor or higher, and a rise in the water level in the drainage mass is detected by the inundation sensor. In this case, the lift device has a function of preventing the lift device from descending to the pit.

According to the present invention, the following excellent effects are exhibited.
(1) In the building, a lift lift unit in the vertical direction leading to the entrance / exit is provided to store the lift device so that it can be driven up and down, and a pit is provided at the bottom of the building that is the lower end of the lift lift unit, By lowering the lift device into the pit, the vehicle can be loaded and unloaded between the loading / unloading port and the upper side of the lifting device, and the loading / unloading work is performed using the lifting device. The lift device in the multi-story parking device that can be made to wait at the upper floor position of the second floor or higher at the time of standby without entering / exiting work, and there is a possibility that water is accumulated in the pit. In some cases, a lift flooding prevention method for a three-dimensional parking device that stops the descent of the lift device to the pit to prevent flooding, and a three-dimensional parking device that has the same configuration as described above. A drainage mass is provided in the pit of the apparatus, a submersion sensor for detecting a rise in the water level in the drainage mass is provided, and control for controlling the lifting and lowering of the lift device based on the signal of the submergence sensor is provided. And a function of causing the lift device to wait on the upper floor of the second floor or higher during standby when the entry / exit operation is not performed, and When the rise of the water level in the drainage mass is detected by the inundation sensor, the lift device has a function to prevent the lift device from descending to the pit. When the building is flooded and water is accumulated in the pit, the lift device will not fall into the pit, so there is a risk that the lift device will be flooded. It can be stopped. Moreover, since the lift device waits at the upper floor position of the second floor or more during standby during loading / unloading work, there is a possibility that the lift device will be flooded even if a large amount of water suddenly enters the pit. Can be prevented. Therefore, it is possible to prevent the possibility that the electrical equipment attached to the lift device will be submerged and adversely affected.
(2) In the above, whether or not there is a possibility that water has accumulated in the pit is determined based on whether or not a rise in the water level in the drainage mass provided at the bottom of the pit is detected. In order to discharge the water that enters the building during the entry / exit operation of the vehicle in rainy weather, it exceeds the drainage capacity of the drainage device generally provided in the drainage mass of the pit of the multilevel parking device as described above When such flooding occurs and water may accumulate in the pit, flooding of the lift device can be reliably prevented.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIGS. 1 (a) and 1 (b) show one embodiment of the method and apparatus for preventing lift flooding of a multilevel parking apparatus according to the present invention. In an elevator type multilevel parking apparatus having the same configuration as shown in FIG. A drainage mass 23 is provided at a required portion of the inner bottom of the vehicle, and a drainage device (not shown) for draining water from the inner bottom of the drainage mass 23 is provided. Make it possible to drain the water that enters the interior. Further, an inundation sensor 24 such as a float switch for detecting a water surface level is provided at a required height position in the drainage mass 23. Furthermore, a controller 25 having a function of giving a command to the hoisting device 11 based on a control law described later in accordance with a detection signal input from the water immersion sensor 24 to control the lifting operation of the lifting device 9 is provided. The configuration.

  More specifically, the height position where the inundation sensor 24 is installed is such that the amount of water entering the building 1 exceeds the drainage capacity of the drainage device provided in the drainage mass 23, thereby causing the water level in the drainage mass 23. Is installed at a required height level, for example, at the upper required position in the drainage mass 23. Thereby, inundation occurs in the building 1 due to heavy rain such as torrential rain or the occurrence of flood, and the amount of water entering the pit 13 exceeds the drainage capacity of the drainage device, and the water level rises in the drainage mass 23. When the drainage mass 23 is almost full, a water level detection signal is output from the water immersion sensor 24. When the detection signal from the inundation sensor 24 is input to the controller 25, it is possible to immediately determine that there is a possibility that water that cannot be received in the drainage mass 13 is starting to accumulate in the pit 13. is there.

  The entrance / exit 2 of the building 1 is configured to include an entrance / exit door (not shown). In addition, an entry start switch 27 for starting the entry operation of the vehicle 5 on the outside required part of the building 1 near the entry / exit port 2, for example, the outer wall of the building 1, and an exit for starting the exit operation. An operation panel 26 having a start switch 28 and a door closing switch 29 for closing the entry / exit door of the entry / exit port 2 is provided, and the operation panel 26 is connected to the controller 25.

  FIG. 2 shows a basic control flow of the control law in the controller 25. As a precondition, the controller 25 sets the lift device 9 to the second floor or higher during standby when the warehouse operation is not performed. It is made to wait on the upper floor (step 1: S1). In this standby state, when the warehousing start switch 27 or the warehousing start switch 28 on the operation panel 26 is operated to start the warehousing operation (step 2: S2), the controller 25 Based on whether or not a detection signal is input from the sensor 24, it is determined whether or not the drainage mass 23 in the pit 13 is full (step 3: S3). In step 3 (S3), when the detection signal from the submergence sensor 24 is input, the drainage mass 23 is full, and thereafter water may start to accumulate in the pit 13 immediately thereafter. In this case, the lift device 9 is prevented from being suspended and submerged in the pit 13 where the water may start to accumulate. 9 is prevented from falling into the pit 13 (step 5: S5), and held in the standby state of step 1 (S1).

  On the other hand, when the detection signal from the inundation sensor 24 is not input to the controller 25 in the step 3 (S3), the drainage mass 23 is not full, and therefore the water in the pit 13 is not filled. Since the controller 25 can determine that there is no possibility of accumulating, the controller 25 has the lift device 9 placed on the empty pallet 6 in the same manner as the conventional elevator type multi-story parking device shown in FIG. Alternatively, the vehicle is suspended in the pit 13 with the actual vehicle pallet 6 of the vehicle to be shipped 5 mounted, and the warehousing operation or the warehousing operation is started (step 6: S6), and then a predetermined warehousing operation is performed. When completed (step 7: S7), the process returns to step 1 (S1), and the lift device 9 is made to stand by in a state where it is lifted up to the second floor or higher.

  Further, in the present embodiment, the controller 25 has a function of controlling the operation of the lateral feed device 10 provided in the lift device 9 and the loading / unloading port 2 (not shown) as shown in FIG. A function for controlling the opening / closing operation of the entry / exit door is also provided.

  Other components that are the same as those shown in FIG.

  The procedure for using the elevator type multi-story parking apparatus as the above configuration will be specifically described. In order to store the vehicle 5, when a user (not shown) operates the storage start switch 27 with the operation panel 26, the controller 25 receives the signal and first waits on the upper floor of the second floor or higher. As in the case of the warehousing operation in the conventional elevator type multi-story parking apparatus shown in FIG. 3, an empty pallet 6 corresponding to the required shelf 7 is placed on a certain lift device 9, and then the hoisting device 11, the lift device 9 is lowered into the pit 13 so that the empty pallet 6 is placed inside the loading / unloading port 2, and then the loading / unloading door of the loading / unloading port 2 is opened. Let's make it.

  Thereafter, after the user enters the vehicle 5 onto the empty pallet 6 through the entrance / exit 2, the user gets out of the vehicle 5, exits from the entrance / exit 2, and confirms the safety. When the door closing switch 29 is operated, the controller 25 closes the entry / exit door of the entry / exit port 2 and then lifts the lift device 9 by the hoisting device 11 so that the vehicle 5 is mounted. The pallet 6 is raised until it corresponds to the height position of the parking planned shelf 7, and then the vehicle 5 is moved along with the pallet 6 by the lateral feed device 10 of the lift device 9 and stored in the shelf 7. Thereafter, the controller 25 causes the lift device 9 emptied by storing the actual vehicle pallet 6 in the shelf 7 to stand by in a stopped state.

  After that, when the warehousing start switch 27 of the operation panel 26 is operated so that another vehicle 5 can be continually stored, the controller 25 gives a command to the hoisting device 11 to cause the lifting device 9 to move. After raising and lowering to a position corresponding to the required shelf 7 in which the empty pallet 6 is stored and mounting the empty pallet 6 of the shelf 7 on the lift device 9, the lift device 9 is lowered into the pit 13. Then, let the warehouse work in the same procedure as above.

  On the other hand, when leaving the parked vehicle 5 stored in the building 1, the user uses the input panel (not shown) to indicate the number assigned to each parked vehicle 5 on the operation panel 26, for example. When the target vehicle 5 of the exit work is specified by inputting and the exit start switch 28 of the operation panel 26 is operated, the controller 25 receives the signal, and first, on the upper floor of the second floor or higher, When the lift device 9 is on standby with the empty pallet 6 mounted, an appropriate command is given to the hoisting device 11 in advance to place the lift device 9 on the shelf 7 corresponding to the empty pallet 6 on the lift device 9. After raising and lowering to the corresponding position, the empty pallet 6 is stored in the corresponding shelf 7 by the transverse feed device 10 of the lift device 9 to make the lift device 9 empty once. On the other hand, when the lift device 9 is waiting in an empty state, it may remain in that state. Next, the controller 25 gives a command to the hoisting device 11 and stores the empty lift device 9 in the unloading target vehicle 5 in the same manner as the unloading work in the conventional elevator type multi-story parking apparatus shown in FIG. The elevator 7 is moved up and down so as to correspond to the required height position of the shelf 7, and then the actual vehicle pallet 6 of the delivery target vehicle 5 is moved from the shelf 7 by the transverse feed device 10 of the shelf 7 and the lift device 9. To be mounted on the lift device 9. Next, the controller 25 gives a command to the hoisting device 11 to lower the lift device 9 into the pit 13, and then opens the entrance / exit door of the entrance / exit 2.

  In this state, the user drives the unloading target vehicle 5 that has been transferred to the loading / unloading port 2 and rides outside from the pallet 6 on the lift device 9 via the loading / unloading port 2. Thereafter, when the user confirms safety and then operates the door closing switch 29 of the operation panel 26, the controller 25 closes the loading / unloading door of the loading / unloading port 2 and then closes the hoisting device 11. A lift device 9 which is provided with an instruction and places the empty pallet 6 after the vehicle 5 is delivered is arranged on the upper floor of the pit 13 or more, for example, as shown in FIG. After raising to the 2nd floor position, it is made to wait until the next loading / unloading work is started at this position.

  Furthermore, when a flood occurs in the building 1 due to heavy rain such as torrential rain or the like, a large amount of water enters the pit 13 and exceeds the drainage capacity of the drainage device attached to the pit 13. When the water level in the drainage mass 23 rises and is detected by the inundation sensor 24, and a detection signal from the inundation sensor 24 is input to the controller 25, the controller 25 enters the pit 13. It is determined that there is a possibility that water has accumulated, and a command is immediately given to the hoisting device 11 so that the lifting device 9 is not lowered into the pit 13.

  That is, for example, when the detection signal from the inundation sensor 24 is input to the controller 25 before the start of the warehousing operation, the controller 25 does not give a command to the hoisting device 11 or By issuing a stop command, the lift device 9 that has been waiting on the upper floor of the second floor or higher is held in its standby position and is not lowered into the pit 13.

  Further, when the detection signal of the inundation sensor 24 is input to the controller 25 while the lift device 9 carrying the empty pallet 6 is lowered toward the pit 13 to perform the warehousing operation. The controller 25 immediately gives a stop command to the hoisting device 11 to immediately stop the lowering operation of the lifting device 9 so that the lifting device 9 does not descend into the pit 13.

  Further, the detection signal from the inundation sensor 24 is input to the controller 25 while the actual vehicle pallet 6 of the vehicle 5 that is received along with the warehousing operation is mounted on the lift device 9 and is transported to the storage shelf 7. In that case, since the lift device 9 does not descend to the pit 13 even if the transfer work of the actual vehicle pallet 6 to the storage planned shelf 7 is continued thereafter, the controller 25 receives the warehousing described above. In the same manner as in the work, the lift device 9 is raised to a position corresponding to the shelf 7 to be stored, and then the vehicle 5 is moved from the lift device 9 to the shelf 7 together with the pallet 6 and stored. The lift device 9 is stopped on the spot to be in a standby state.

  On the other hand, when the detection signal of the inundation sensor 24 is input to the controller 25 before the start of the warehousing operation, the controller 25 does not issue a command to the hoisting device 11, so The lift device 9 that is to be on standby at the upper floor is held in the standby position as it is so as not to be lowered into the pit 13.

  In addition, the detection signal of the inundation sensor 24 is input to the controller 25 while the lift device 9 on which the actual vehicle pallet 6 of the vehicle 5 to be discharged is mounted is lowered toward the pit 13 in order to perform the output operation. In this case, the controller 25 immediately gives a stop command to the hoisting device 11 to immediately stop the lowering operation of the lifting device 9 so that the lifting device 9 is not lowered into the pit 13. Like that.

  In the case where the descent of the lift device 9 into the pit 13 is stopped based on the detection signal of the inundation sensor 24 during the loading / unloading operation, the lift device is intended to prevent flooding of the lift device 9. Since the operation of No. 9 is stopped, it is desirable to notify the user who is going to perform the loading / unloading work by displaying on the operation panel 26 that the loading / unloading work cannot be performed.

  After that, when the water in the building 1 stops and the water in the pit 13 is drained by the function of the drainage device installed in the drainage mass 23 and the water level in the drainage mass 23 is lowered, the detection from the flooding sensor 24 is performed. Since the signal is not input to the controller 25, the controller 25 allows the lift device 9 to descend into the pit 13. For this reason, a normal loading / unloading operation can be performed.

  Thus, according to the lift flooding prevention method and apparatus of the multilevel parking apparatus of the present invention, inundation occurs in the building 1 due to heavy rain such as torrential rain or the occurrence of flooding, and a large amount of water enters the pit 13. If there is a possibility of accumulating in the pit 13, the lift device 9 is not lowered into the pit 13, so that it is possible to prevent the lift device 9 from being flooded. Moreover, since the lift device 9 is made to wait in advance at a position on the upper floor of the second floor or higher during standby during the loading / unloading work, a large amount of water enters the pit 13 at a high speed. In addition, it is possible to reliably prevent the lift device 9 from being flooded. Therefore, it is possible to prevent the electrical equipment such as the lateral feed device 10 attached to the lift device 9 from being submerged and being adversely affected.

  In addition, this invention is not limited only to the said embodiment, The lift apparatus 9 is equipped with the pit 13 provided in the inner bottom part of the building 1 used as the inner side of the entrance / exit 2 and the lift raising / lowering part 3 above it. If it is an elevator-type three-dimensional parking apparatus that is configured to move the parked vehicle 5 between the entrance / exit 2 of the building 1 and the storage space 4 in the building 1 by moving up and down, for example, a lift device 9 Is lifted and lowered by a lifting drive device other than the hoisting device 11 that winds and lowers the wire rope 12, and between the lift device 9 and the shelves 7 provided in multiple layers in the storage space 4. The lateral feed device for delivering the pallet 6 is provided only on either the lift device 9 side or the shelf 7 side, on the upper side of the lift device, and on each shelf 7 of the storage space 4 on the upper side. The vehicle 5 is directly placed on the lateral feed device of the lift device suspended from the loading / unloading port 2 into the pit 13 and equipped with a lateral feed device that allows both to be placed directly and laterally fed. After the lift device 9 is raised to the required shelf position, the vehicle can be transferred from the lift device to the shelf by cooperating the lift device and each lateral feed device on the shelf 7 side. It can be applied to any type of elevator type multi-story parking device. Moreover, you may change suitably the shape of the building 1, and arrangement | positioning of the shelf 7 in the storage space 4 in the building 1. FIG.

  Although the operation panel 26 is shown as comprising a warehousing start switch 27, a warehousing start switch 28, and a door closing switch 29, these switches 27, 28, 29 may be of any type, and You may make it equip suitably the various switches which are conventionally provided in the operation panel of the elevator type three-dimensional parking apparatus, and the key for inputting the data of the vehicle 5 to leave, a PIN code, etc. Furthermore, the door closing switch 29 may be omitted if it is possible to automatically confirm that the building 1 is unmanned and to confirm safety.

  The controller 25 has a function of causing the lift device 9 to wait on the upper floor of the second floor or higher and a detection signal from the inundation sensor 24 at least during standby when the loading / unloading work is not being performed. It is only necessary to have a function of preventing the descent into the pit 13, a function of controlling the operation of the lateral feed device 10 provided in the lift device 9, and an opening / closing operation of a loading / unloading door (not shown) of the loading / unloading port 2. Another controller may have a function of controlling the above. Or you may make it have a control function desired in order to operate an elevator-type three-dimensional parking apparatus.

  Of course, various changes can be made without departing from the scope of the present invention.
