The loading / unloading port 3 is provided with a door (not shown).

  As shown in FIGS. 3, 4, and 5, the lift cage 5 includes a pair of beam members 10 arranged in parallel on both left and right sides of the hoistway 4 so as to extend in the front-rear direction. On the surface portions of each beam member 10 facing each other, two or more wheel supporting members 11 projecting inward in the horizontal direction are provided at two positions in the front-rear direction (longitudinal direction) (six in the figure) and in the front-rear direction. They are mounted in a comb-like arrangement with a space between them. As a result, the lift cage 5 can receive and support the front and rear wheels of the vehicle 1 by the wheel support members 11.

  Guide members 12 extending in the vertical direction are attached to both ends of each beam member 10 in the front-rear direction via connecting members 13. The hoistway 4 is provided with a guide rail 14 for raising and lowering a U-shaped cross section that extends in the up-down direction along the front and rear walls of the building 2 at a square portion, and each guide member 12 is The guide rails 14 are fitted so as to be vertically slidable.

  Further, as shown in FIG. 1, a lifting drive device 15 such as a winch is installed at the top of the building 2, and a hanging member 16 such as a wire or a chain fed from the lifting drive device 15 is installed. The front end side is connected to the upper end side of each guide member 12, as shown in FIGS. As a result, the lift cage 5 is supported in a state of being suspended by the lifting drive device 15 via the suspending member 16. Therefore, the lift cage 5 is raised in the hoistway 4 by the winding operation of the hanging material 16 by the lifting drive device 15, and the lift cage 5 is lowered in the hoistway 4 by the feeding operation of the hanging material 16.

  Further, as shown in FIGS. 3 and 5, the lift cage 5 is provided with connecting means 8 below the portions of the beam members 10 near the front and rear ends so as to project downward. The specific configuration of the connecting means 8 will be described later together with the connecting means 9 on the turntable device 7 side.

  As shown in FIG. 3, the turntable device 7 includes a base frame 17, an elevating frame 18 vertically movably held on the upper side of the base frame 17, and a horizontally rotatably upper side of the elevating frame 18. The turning frame 19 and the turning table body 20 mounted on the turning frame 19 are provided. Further, in the turntable device 7, although not shown, an elevating means for elevating the elevating frame 18 with the base frame 17 as a reference and a revolving table main body 20 with the revolving frame 19 for revolving with the elevating frame 18 as a reference. A turning means is provided.

  As shown in FIG. 5, the turntable main body 20 has, for example, a tip end portion of each of the left and right wheel support members 11 of the lift cage 5 in order to have a flat shape so that the lift cage 5 can pass through the outside in the vertical direction. The beam member 21 extends in the front-rear direction with a lateral width narrower than the interval. On each of the left and right sides of the front and rear of the beam member 21, a plurality of wheel receiving members 22 protruding outward in the horizontal direction (five in the figure) are arranged in a comb-like shape at intervals in the front-rear direction. It is installed in the installed state. The positions of the wheel receiving members 22 in the front-rear direction are set so as not to overlap with the wheel support members 11 and to be alternately arranged in the front-rear direction. Plate members 23 projecting outward in the horizontal direction are provided on the left and right sides of the center portion of the beam member 21 in the front-rear direction, and the wheel supporting members 11 on the front side and the wheel supporting members 11 on the rear side of the lift cage 5. It is attached so that it can pass between them.

  The turntable main body 20 is arranged such that the upper surface side thereof is at the same height as a platform 45 (see FIG. 5) described later that constitutes the floor of the first floor of the building 2.

  The turntable device 7 is configured such that each wheel receiving member 22 can support and support each wheel of the vehicle 1 that is loaded from the loading / unloading port 3 or the vehicle 1 that is loaded from the loading / unloading port 3.

  In the turntable device 7, with the vehicle 1 placed on the upper side of the turning table body 20, first, the turning table body 20 is placed in the pit 6 together with the lifting frame 18 and the turning frame 19 by the lifting means. The lift cage 5 and the platform 45 (see FIG. 5) are lifted to a position above. Next, the turntable device 7 turns the turning table main body 20 together with the turning frame 19 in the circumferential direction by, for example, 180 degrees by the turning means, and then uses the lifting means to move the lifting frame 18 and the turning frame 19 to each other. Together, the turning table body 20 is returned to the initial height position. As a result, the turntable device 7 can change the direction of the vehicle 1 together with the turning table body 20.

  Further, as shown in FIGS. 3 and 6A, positioning pins 24 are provided so as to project downward at a plurality of positions on the lower surface side of the base frame 17. On the other hand, on the inner bottom of the pit 6, a plurality of pedestals 25 are installed in accordance with the arrangement of the positioning pins 24 of the base frame 17. Each pedestal 25 has a fitting hole 26 for inserting the positioning pin 24 on the upper surface side.

  When disposing the turntable device 7 in the pit 6, the turntable device 7 is moved from the upper side to the lower side so that each positioning pin 24 is inserted into the fitting hole 26 of each pedestal 25 from above. . As a result, the turntable device 7 is supported by each pedestal 25. In this state, the displacement of each positioning pin 24 in the horizontal direction is constrained by the fitting hole 26 of each pedestal 25, so that the turntable device 7 is prevented from being displaced in the horizontal direction in the pit 6. .

  Further, a lower end side of a column member 27 extending in the vertical direction is attached to the base frame 17 at a position facing the connecting means 8 of the lift cage 5 in the vertical direction. The connecting means 9 is provided on the upper end side of each pillar member 27.

  When each pillar member 27 lifts the turntable device 7 by the lift cage 5 in a state where the connecting means 8 and the connecting means 9 are connected to each other as described later, the weight of the turntable device 7 acts as a vertical tensile load. To do. Therefore, from the viewpoint of reducing the weight of the turntable device 7, each pillar member 27 includes a plurality of vertically extending bar members 28, for example, four bar members 28, as shown in FIG. 6A. It is preferable that the rod member 28 and the plate member 29 connect the upper ends of the rod members 28 to each other. In this case, the lower end side of each rod 28 is attached to the base frame 17, for example, a screw portion is provided at a position near the lower end of each rod 28, and the screw portion is provided with an insertion hole (not shown) provided in the base frame 17. The lower end side of each rod 28 may be fixed to the base frame 17 by the nuts 30 provided on both upper and lower sides of the insertion point.

  Note that the pillar member 27 may be configured to use a plurality of pipe members instead of the plurality of rod members 28, and the pillar member 27 may be configured to be a single rod member or a pipe member. The structure of the member 27 is not limited to the illustrated structure. Further, it goes without saying that the method of attaching the pillar member 27 to the base frame 17 on the lower end side may be appropriately changed according to the configuration of the pillar member 27.

  Next, configurations of the connecting means 8 and the connecting means 9 will be described with reference to FIGS. 6 (a), (b), (c), and (d).

  The connecting means 8 on the side of the lift cage 5 is, for example, as shown in FIG. 6A, a hook member 32 that is swingably hung below the beam members 10 via a bracket 31, and a hook member. And a guide member 33 attached to the lower side of 32. The guide member 33 is provided at its lower end side with an inclined surface 34 that inclines downward from the hook-shaped opening side of the hook member 32 toward the opposite side. The bracket 31 is provided with a stopper 35 that stops the swing of the hook member 32 toward the opening side. Further, although not shown, an urging means such as a spring for urging the hook member 32 toward the opening side is provided between the hook member 32 and the member fixed to the bracket 31 or the beam member 10. Good.

  On the other hand, the connecting means 9 on the turntable device 7 side has a structure in which a locking hole 37 is formed in the plate material 36. The plate member 36 is attached to a position immediately below the inclined surface 34 of the guide member 33 on the upper end side of the column member 27 in a posture orthogonal to the swinging direction of the hook member 32.

  In the present embodiment, as shown in FIGS. 1 and 3, when the lift cage 5 is arranged at the lower limit position L of the ascending / descending range during normal operation, the upper surface of each wheel support member 11 causes the wheels of the turning table body 20 to rotate. It is arranged at a height position equivalent to the upper surface of the receiving member 22 or at a position lower than that.

  FIG. 6A shows a state in which the lift cage 5 is placed at the lower limit position L in the normal lifting range. In this state, the hook member 32 of the connecting means 8 on the lift cage 5 side is It is arranged above the connecting means 9 on the turntable device 7 side with a gap. In order to obtain the relative arrangement of the connecting means 8 and the connecting means 9, the vertical size of the bracket 31 and the hook member 32 of the connecting means 8 and the connecting means 9 of the turntable device 7 via the pillar member 27. The installation height position is set appropriately.

  As shown in FIG. 6B, when the lift cage 5 is lowered below the lower limit position L of the normal lifting range, the guide member 33 of the connecting means 8 contacts the plate member 36 of the connecting means 9 and the guide member 33 As the inclined surface 34 slides with respect to the plate member 36, the hook member 32 is gradually tilted to the side opposite to the hook-shaped opening.

  After that, the lift cage 5 is further lowered, and when the hook-shaped tip of the hook member 32 becomes lower than the upper end position of the locking hole 37 of the plate member 36 as shown in FIG. , And is inserted into the locking hole 37 by being rotated by its own weight or by the biasing force of a biasing means (not shown). The height position of the lift cage 5 at this time becomes a target position F for descending during flooding which is a target when the lift cage 5 is descended when the pit 6 is flooded.

  As shown in FIGS. 2 (a) and 6 (c), the inundation target position F for the lift cage 5 is different from the lower limit position L in the normal lift range when the lift cage 5 moves up and down. It is set to be located below with a significantly larger difference (significant difference).

  When the lift cage 5 is lifted from the state shown in FIG. 6C, the hook member 32 is locked in the locking hole 37 of the plate member 36 as shown in FIG. The connecting means 9 are connected to each other. Since the turntable device 7 is not fixed in the pit 6 but is supported by each pedestal 25, if the lift cage 5 is further raised after the connecting means 8 and the connecting means 9 are connected, The table device 7 is supported by the lift cage 5 in a suspended state via the connecting means 8 and 9.

  Therefore, thereafter, as shown in FIG. 2B, the lift cage 5 is pulled up from inside the pit 6 to the hoistway 4, and the lift cage 5 is further raised, so that the turntable device 7 is located above the pit 6. It can be lifted up to the position.

  When rearranging the turntable device 7 suspended by the lift cage 5 in the pit 6 as described above, the lift cage 5 is lowered into the pit 6 so that the turntable device 7 can be received by each pedestal 25. Hang it to the position where it is supported. After that, the lift cage 5 is once lowered to the water immersion lowering target position F shown in FIG. 6C, and in this state, the hook members 32 are pulled out from the locking holes 37 of the plate members 36, and the connecting means is connected. The engagement between 8 and the connecting means 9 is released. The operation of each hook member 32 for unlocking may be manually performed by an operator in sequence, and the unlocked hook member 32 uses a cord or a temporary fixing tool (not shown). To hold the unlocked posture temporarily. In this state, the lift cage 5 is raised to a position where the hook members 32 are arranged above each plate member 36 with a gap, and then the hook members 32 are temporarily released from the unlocked posture. By canceling the holding, the lift cage 5 and the turntable device 7 return to the normal operation state in which they are not interconnected.

  Further, the elevator parking apparatus of the present embodiment includes the water level sensor 38 that detects the water level in the pit 6 so that the water in the pit 6 can be automatically detected. The water level sensor 38 is for detecting the water level in the pit 6 before reaching the water level at which the turntable device 7 is hindered.

  As the water level sensor 38, for example, a float switch may be used. The float switch detects the water level by direct contact with water. Therefore, as shown in FIG. 3, the water level sensor 38 is attached near the bottom of the side wall of the pit 6.

  Although not shown, the water level sensor 38 may be attached to the bottom portion of the pit 6 via attachment members having desired upper and lower dimensions. Further, when the drainage mass is provided at the bottom of the pit 6, the water level sensor 38 may be provided inside the drainage mass. In this case, since the water level sensor 38 detects when water is collected in the drainage mass, it is possible to detect the infiltration of water in the pit 6 earlier.

  Although the float switch is illustrated as the water level sensor 38, it is needless to say that any type of water level sensor other than the float switch may be used as long as the water level in the pit 6 can be detected. Further, the water level sensor 38 is not limited to the type that detects the water level by direct contact with water, and a water level sensor that detects the water surface in the pit 6 in a non-contact manner may be used. It goes without saying that such a water level sensor that detects the water level without contacting with water may be appropriately arranged in the pit 6 according to the detection method, the detection target, and the like.

  Further, although not shown, the pit 6 is equipped with a drainage means such as a drainage pump for draining water that gradually enters the pit 6, such as rainwater accompanied by the vehicle 1 entering in the rain.

  Further, the elevator type parking apparatus of the present embodiment has a structure as shown in FIG. 7 in order to perform the processing of lifting the turntable device 7 above the pit 6 by the lift cage 5 as described above when the pit 6 is flooded. A control system having a control device 39 is provided.

  The control device 39 uses the evacuation command generation unit 39a that generates the evacuation start command c for the turntable device 7 and the evacuation command generation unit 39a based on the input of the water immersion detection signal s from the water level sensor 38. When the evacuation start command c is input, an elevating control unit 39b that gives a command to the elevating drive device 15 to control the elevating operation of the lift cage 5 is provided.

  A manual operation-type evacuation command switch 40 is connected to the elevating control unit 39b, and an evacuation start command c generated by an operator operating the evacuation command switch 40 is also input to the elevating control unit 39b. Has become.

  The control device 39 is preferably provided in an existing elevator-type parking device of the type including the comb-teeth-shaped lift cage 5 and integrally provided in the control device that performs the loading / unloading process of the vehicle 1, but the existing control is not provided. Of course, it is not limited to the configuration integrated with the device.

  In any case, when the evacuation start command c is input to the elevating control unit 39b, the control device 39 gives priority to the normal loading / unloading process of the vehicle 1 by the elevator parking device, and the turntable device 7 is performed. The saving process of is started.

  When the evacuation start command c is input, the elevating control unit 39b gives a command to the elevating drive device 15. As a result, the lift cage 5 descends into the pit 6 as shown in FIG. 2A, and further descends beyond the lower limit position L of the normal ascending / descending range to the inundation descending target position F. When the lift cage 5 is arranged in this way, as shown in FIG. 6C, the tip of the hook of the hook member 32 of the connecting means 8 on the lift cage 5 side is connected to the connecting means on the turntable device 7 side. 9 is inserted into the locking hole 37.

  Next, as shown in FIG. 2B, the lifting drive device 15 raises the lift cage 5 in the hoistway 4 and suspends it from the lift cage 5 via the connecting means 8 and the connecting means 9. The turntable device 7 in the state is lifted to a position above the pit 6. After that, the lifting drive device 15 is stopped.

  In this state, even if the pit 6 is flooded, the turntable device 7 is prevented from being submerged (submerged).

  As described above, when the evacuation start command c is input to the lift control unit 39b, the vehicle 1 is placed on the lift cage 5 or the vehicle 1 is placed on the turning table body 20 of the turntable device 7. In such a case, if the above-described retracting process of the turntable device 7 is started as it is, the weight of the turntable device 7 is supported by the lift cage 5 in addition to the weight of the vehicle 1. Therefore, as a countermeasure in such a case, assuming that the weight of the vehicle 1 and the weight of the turntable device 7 are loaded on the lift cage 5 in advance, the lifting drive device 15 that suspends the lift cage 5, The performance (capacity) of the hanging material 16 may be determined.

  In such a case, the performances of the lifting drive device 15 and the suspending member 16 become excessive with respect to the load acting during the normal operation of transporting the vehicle 1 by the lift cage 5.

  Therefore, as another countermeasure, when the control device 39 inputs the evacuation start command c to the elevating control unit 39b, the vehicle 1 is mounted on the lift cage 5 or on the turntable body 20 of the turntable device 7. When the vehicle 1 is installed in the vehicle 1, first, the vehicle 1 may be provided with the function of performing the same warehousing process as in the normal operation. By this warehousing process, the state in which the vehicle 1 is placed on the lift cage 5 or the turning table body 20 is eliminated. Therefore, the control device 39 may thereafter perform the evacuation process of the turntable device 7 described above by the elevating control unit 39b. By doing so, the weight of the vehicle 1 and the weight of the turntable device 7 are not simultaneously applied to the lift cage 5, so that the weight of the vehicle 1 or the turntable device 7 becomes larger depending on which one is larger. The performances of the lifting drive device 15 and the suspension 16 can be determined. In general, the weight of the turntable device 7 is often equal to or less than the weight of the vehicle 1. Therefore, the performances of the lifting drive device 15 and the suspension member 16 in the present embodiment are the same as those of the existing elevator type. It becomes possible to set it like the parking device.

  As shown in FIG. 1, left and right positions on both sides of the hoistway 4 in the building 2 are storage spaces 41, and each storage space 41 is formed with a plurality of shelves 42 in the vertical direction. A comb tooth-shaped pallet 43 shown in FIG. 4 is stored in each of the shelves 42 in a state where both front and rear ends thereof are held by a lateral feed device 44 between the shelves 42 and the hoistway 4.

  As shown in FIG. 4, the pallet 43 has, for example, a beam similar to the beam member 21 and the wheel receiving member 22 of the turning table body 20 in order to have a planar shape that allows the lift cage 5 to pass through the outside in the vertical direction. A member 43a and a wheel receiving member 43b are provided, and guide members 43c for engaging with the lateral feed device 44 are attached to both front and rear ends of the beam member 43a so as to project in the left-right direction.

  On the floor of the first floor of the building 2, as shown in FIG. 5, platforms 45 are provided on both front and rear sides and on both left and right sides of the turntable main body 20 of the turntable device 7. Each platform 45 is arranged so as not to interfere with the vertical movement (passage) of the lift cage 5. The platform 45 serves as a traveling path when the vehicle 1 travels between the turning table body 20 and the loading / unloading port 3, and also serves as a floor on which a driver or a passenger of the vehicle 1 gets in and out.

  In the case where each platform 45 is a fixed type, the base frame 17, the lifting frame 18, the swing frame 19, the column member 27, and the connecting means 9 of the turntable device 7 are all of the planar shape of the swing table body 20 and the lift cage 5. It is set to fit inside.

  On the other hand, it is conceivable that the planar shapes of the base frame 17, the lifting frame 18, the swivel frame 19, the column member 27, and the connecting means 9 of the turntable device 7 may exceed the planar shapes of the swivel table main body 20 and the lift cage 5. In this case, the platform 45 located above the protruding portion is provided with a function of automatically partially bending when the turntable device 7 is lifted or automatically partially sliding outward and retracting. You can do it like this. In this way, there is no interference between the platform 45 and the turntable device 7 that moves the pit 6 upward.

  When the vehicle 1 is loaded using the elevator type parking apparatus of the present embodiment having the above-described configuration, as shown in FIG. 1, the lift cage 5 is suspended in advance to the lower limit position L of the normal lifting range.
