In each of these drainage devices, a water receiving tank for collecting the above-mentioned snow-melting water or the like is provided on the lower surface of the pallet (for example, see Patent Documents 1 and 2). Therefore, the height of the entire pallet is increased by the height of the water receiving tank. As a result, in the conventional drainage device, the separation distance between shelves for storing pallets, which are vertically stacked in the multi-story parking facility, is increased, and the number of vehicles accommodated in the multi-story parking facility per unit volume is reduced. Become.
[0004]
The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a pallet drainage device capable of discharging water accumulated on a pallet without significantly increasing the height of the pallet. I do.

[Means for Solving the Problems]
The pallet drainage device according to the present invention is a pallet drainage device provided in a mechanical parking device, which is applied to a pallet for mounting on a vehicle having a lane having a concave cross section. Weirs installed at both ends in the direction to store water on the lane, and drainage installed outside the side wall of the lane, communicating with the lane and discharging water accumulated on the lane Means, a displacement means attached to the outside of the side wall of the lane, displacement means for displacing the drainage means, provided on the entry and exit floor for entering and exiting the vehicle, operating means for operating the displacement means, The drainage means has a receiving part for receiving water from the lane and a drainage hose for discharging the received water, and the drainage hose has an upper position where water does not flow out of the drainage hose by the displacement means and a lower position where water is discharged. Is configured to be displaced to Ri, receiving join the club is attached in communication with the side wall of the vehicle path, the displacement means when the actuating means is actuated displacement means are no drainage hose to displace to the lower position.
[0007]
According to this configuration, the height of the pallet hardly increases because the drainage means and the displacement means are mounted outside the side walls of the two lanes. Therefore, the drainage device for pallets according to the present invention significantly increases the separation distance between shelves stacked in a multi-story parking facility as compared with conventional pallets, or reduces the number of vehicles accommodated in the multi-story parking facility per unit volume. Is rarely reduced. When the pallet arrives at the loading / unloading floor, the operating means displaces the displacement means, whereby the discharging means is displaced to the lower position and the water in the lane is discharged. Since water is discharged at the entrance / exit floor in this manner, disposal of the discharged water is easy.
[0008]
The present invention further includes a backing plate abutting from a rear side of the lane to a first opening corresponding to a receiving portion provided from the bottom of the lane to the side wall, and the plate corresponds to the first plate. A second opening communicating with the opening may be provided, and the receiving portion may be attached to the backing plate so as to communicate with the second opening. As a result, a lower portion is formed at the bottom of the road by an amount corresponding to the thickness of the bottom of the road, and water on the road flows to this portion. As a result, drainage on the roadway is improved. Further, the second opening of the backing plate may be extended to the bottom side of the road. In this case, a lower portion is formed at the bottom of the road by an amount corresponding to the plate thickness of the bottom of the road and the plate thickness of the abutment plate. As a result, drainage on the roadway is improved as described above. Further, since the amount of increase in the height of the pallet is only the thickness of the backing plate, the height of the pallet does not increase significantly. Furthermore, the contact plate can also prevent the strength of the pallet from being reduced due to the provision of the first opening in the roadway.
[0009]
A plurality of the drainage units may be arranged in the longitudinal direction of the lane. Thus, even when water is unevenly distributed on the road due to inclination or bending of the road, water from the road can be easily drained by the drainage means arranged in the longitudinal direction of the road. . As a result, drainage on the roadway is improved. Further, by providing a plurality of drainage means, the volume (dimension) per drainage means can be reduced, so that even if it is necessary to increase the capacity of the drainage means, the number of drainage means installed By increasing the number of pallets, an increase in the height of the pallet can be avoided.
[0010]
The displacing means includes a tip connected to a drain hose and a central part rotatably attached to the pallet, and the displacing means pivots the tip in the vertical direction about the central part. Thereby, the drainage hose may be configured to be displaced between the upper position and the lower position. The displacement means may be configured to further include a biasing means for holding the drain hose at the upper position.
[0011]
In this configuration, since the distal end of the displacement means is vertically rotated about the center of the displacement means, the drain hose connected to the distal end of the displacement means is also vertically displaced. As a result, it becomes possible to store water in the lane or to discharge water that has accumulated in the lane from the drain hose. Further, when the displacement means is not operated, the urging means holds the drain hose at the upper position, and water does not flow out of the drain hose, so that water can be stored in the lane. Note that, for example, a spring is used as the urging means.
[0012]

It is a BB line arrow view of a).
[0019]
An elevator 3 for raising and lowering a pallet 2 on which a vehicle M is mounted is suspended by a wire (not shown) inside the parking tower 10 of the elevator-type parking device 1, and the wire is wound up and fed out. A driving device (not shown) for raising and lowering the elevator 3 and a counterweight (not shown) are provided. A plurality of parking shelves (hereinafter, also simply referred to as shelves) 4 are vertically arranged on both sides of the hoistway of the elevator 3.
[0020]
Further, a pit 6 is dug on the floor of the first floor of the entrance and exit floor E where the vehicle M enters and exits, and the pallet 2 is received from the elevator 3 on the floor in the pit 6 to enter and exit the vehicle M. A swivel device 5 is provided for swiveling to a position where it can be operated. When the pallet 2 is mounted on the turning device 5, the upper surface (vehicle mounting surface) of the pallet 2 coincides with the floor surface (vehicle entrance surface) of the entrance / exit floor E.
[0021]
In the above configuration, the elevator 3 rises to the shelf 4 of the called pallet 2 between the shelves 4 on both sides, receives the pallet 2 and lowers it to the entrance / exit floor E. After the vehicle 2 is loaded on the pallet 2, the elevator 3 moves up to the original shelf 4 again, passes the pallet 2 to the shelf 4, and the pallet 2 is placed on the shelf 4.
[0022]
As shown in FIG. 2, the pallet 2 is made of a steel plate or the like, and has roads 20, 20 having concave cross sections arranged in parallel on both sides on which wheels (not shown) of the vehicle M are mounted. And a ceiling plate 21 for connecting the two. The roadway 20 and the ceiling plate 21 will be described in more detail.
[0023]
Each lane 20 has a long plate-like bottom portion 20a and plate-like side walls 20b on both sides thereof, which rise substantially perpendicularly to the bottom portion 20a. At both ends in the longitudinal direction of each lane 20 (the direction in which the vehicle M enters and the direction of the arrow X in FIG. 2), weirs 22 for storing water on the upper surface of the bottom portion 20a protrude, respectively. Have been. This prevents water from spilling from both ends of each lane 20. The weir portion 22 has a rectangular shape, and both ends in the width direction (the direction of the arrow X in FIG. 2) are bent at a predetermined angle from the horizontal to the bottom portion 20a side and are fixed to the upper surface of the bottom portion 20a. . Both ends of the weir 22 in the direction perpendicular to the width direction are fixed to the inner surface of each side wall 20b.
[0024]
The ceiling plate 21 has a rectangular shape and is provided substantially parallel (in the horizontal direction) to the upper surface of the bottom portion 20a so as to be continuous with the upper edge of the opposite side wall 20b of the roadway 20. It is formed integrally with the roadway 20. Accordingly, a space surrounded by the ceiling plate 21 and the opposing side wall 20b of the roadway 20 is formed below the ceiling plate 21. Although the two roads 20 and the ceiling plate 21 are formed integrally here, the road 20 and the ceiling plate 21 may be formed separately and connected by welding or the like.
[0025]
In each of the lanes 20 of the pallet 2, a drain member 23 and a displacement member 25 corresponding to the drain member 23 of the pallet drain device according to one embodiment of the present invention for discharging water from each lane 20 are respectively provided. Each is attached. The drainage member 23 discharges water from the lane 20 at an appropriate time, and the displacement member 25 displaces the drainage member 23 to discharge water from the drainage member 23. As shown in FIG. 2, the drainage members 23 attached to both the lanes 20 are opposed to the substantially central portion of the space in the longitudinal direction (the direction of the arrow X in FIG. 2) obliquely in plan view. Are located. Similarly, the displacement members 25 corresponding to the drainage members 23 are also arranged at substantially the center of the space in the longitudinal direction (the direction of the arrow X in FIG. 2) so as to face each other obliquely in plan view. The drainage member 23 attached to one roadway 20 and the corresponding displacement member 25 are disposed between the drainage member 23 attached to the other roadway 20 and the corresponding displacement member 25. A long plate-like support plate 24 for supporting the member 23 and the displacement member 25 is provided. The upper end of the support plate 24 is attached to the lower surface of the ceiling plate 21, and both ends in the longitudinal direction are attached to opposing side walls 20b. As described above, since the drainage member 23 and the displacement member 25 are accommodated in the space, the height of the pallet 2 (the separation distance from the lower surface of the bottom 20a of the roadway 20 to the upper surface of the ceiling plate 21) hardly increases.
[0026]
The drainage member 23 and the displacement member 25 will be described in more detail with reference to FIG. Since the drainage member 23 and the displacement member 25 attached to both the lanes 20 have the same configuration, only the configuration of the drainage member 23 and the displacement member 25 attached to one of the lanes 20 will be described here. The description of the configuration of the other drainage member 23 and the displacement member 25 is omitted.
(A) Drainage member 23
As shown in FIGS. 3A and 3B, the drainage member 23 includes a backing plate 231 attached to the rear side of the roadway 20, and a receiving portion 232 mounted on the backing plate 231 to receive water from the roadway 20. And a drain hose 233 attached to the receiving portion 232 and capable of being vertically displaced to drain water from the vehicle path 20.
[0027]
The contact plate 231 is bent along the back surface from the bottom 20a of the roadway 20 to the side wall 20b. The contact plate 231 is in contact with a portion corresponding to the opening 20c provided from the bottom 20a to the side wall 20b of the roadway 20. In addition, two rectangular openings 231a provided from the bottom to the side wall of the contact plate 231 are arranged in the longitudinal direction of the roadway 20 (the arrow X direction in FIG. 3). I have. The opening 231a corresponds to the opening 20c of the road 20, and the water accumulated in the road 20 can be discharged through the openings 20c and 231a. The opening 20c corresponds to a first opening, and the opening 231a corresponds to a second opening.
[0028]
With the above configuration, the upper surface of the bottom of the receiving portion 232 is lower than the upper surface of the bottom 20c of the lane 20 by the thickness of the bottom 20c and the thickness of the abutment plate 231. As a result, a recess is formed at the bottom 20a of the roadway 20. As a result, the water that has accumulated at the bottom 20a of the roadway 20 flows into the concave portion, whereby drainage of the bottom 20a of the roadway 20 is improved. At the same time, the abutment plate 231 also plays a reinforcing role in preventing the strength of the roadway 20 from being reduced due to the provision of the opening 20c in the roadway 20. Here, the backing plate 231 is attached to the back side of the roadway 20. However, when the opening 20c is small and reinforcement is not necessary, the receiving portion 232 is directly provided on the backside of the roadway 20 without passing through the backing plate 231. May be attached.
[0029]
Further, two receiving portions 232 each having a rectangular section and having openings at both ends corresponding to the respective openings 231a are connected to the backing plate 231. The receiving portion 232 is arranged so as to extend in the lateral direction (the width direction of the pallet 2) with respect to the side wall 20 b of the road 20. The reason why the cross section of the receiving portion 232 is rectangular is to widen a frontage for receiving water from the road 20. The receiving portion 232 is made of a steel plate or the like, and is configured to secure a passage through which water flows and to support a drain hose 233 described later.
[0030]
A tubular drain hose 233 having openings at both ends made of a soft material such as vinyl chloride is inserted into an outer peripheral portion of each of the receiving portions 232 opposite to the backing plate 231. A hose band 234 and the like are wound around the outer peripheral portion of the portion where the drain hose 233 is inserted. Thereby, the receiving part 232 and the drain hose 233 are connected. An end portion (hereinafter, referred to as a drainage portion) 233a of the drainage hose 233 on the opposite side to the receiving portion 232 is disposed so as to extend in a lateral direction (the width direction of the pallet 2). The length of the drain hose 233 is such that the drain hose 233 can be vertically displaced. Specifically, the length of the drain hose 233 is desirably about half the width of the ceiling plate 21 in consideration of the attachment of the drain hose 233 and the like. With the above configuration, the drain portion 233a of the drain hose 233 can be easily displaced in the vertical direction.
[0031]
Note that the shapes and the number of the receiving portions 232 and the drainage hoses 233 are not limited to those described above, but are actually set appropriately according to the shape of the pallet 2 and the like.
(B) Displacement member 25
As shown in FIGS. 3A and 3C, the displacement member 25 is attached to the support plate 24. The displacement member 25 includes a long plate-shaped lever 251. The lever 251 has a central portion rotatably attached to the support plate 24 by a connecting pin 252. Thereby, the tip of the lever 251 can be displaced in the vertical direction (the arrow Y direction in FIG. 3C) about the axis of the connecting pin 252.
[0032]
A fastening member 253 such as a wire is attached to the tip of the lever 251, and the fastening member 253 is wound around the outer circumference of the two drainage hoses 233 together with the drainage portions 233 a of the two drainage hoses 233. As a result, the distal end of the lever 251 is connected to the two drains 233a. Accordingly, by displacing the distal end of the lever 251 in the vertical direction (the direction of the arrow Y in FIG. 3C), both the drainage parts 233a can be displaced in the vertical direction.
[0033]
The displacement member 25 includes a biasing member 254 such as a spring that biases both the drainage portions 233a so as to contact the lower surface of the ceiling plate 21. Each end of the urging member 254 is attached to a connecting portion 255 provided at the tip of the lever 251 and a connecting portion 256 protruding from the support plate 24, respectively. The connecting portion 256 is located closer to the ceiling plate 21 than the mounting position of the connecting pin 252, which is the pivot of the lever 251, in order to set the direction of the force of the urging member 254 acting on the tip of the lever 251 to the ceiling plate 21 side. Are located. As a result, both drain portions 233a are urged to contact the lower surface of the ceiling plate 21. In addition, the position where both drains 233a contact the lower surface of the ceiling plate 21 is the upper position where water does not flow out from both drains 233a.
[0034]
In the above configuration, the operating member 30 described later acts upward on the rear end of the lever 251, so that the distal end of the lever 251 is centered on the axis of the connecting pin 252 against the urging force of the urging member 254. And is displaced to a position vertically below the rear end of the lever 251. As a result, both the drains 233a are displaced downward together with the tip of the lever 251, and the water in the lane 20 is discharged to the outside. In addition, the position of both the drains 233a at this time is a lower position where water is discharged from both the drains 233a.
[0035]
Next, the operating member 30 acting on the rear end of the lever 251 will be described with reference to FIG. FIG. 4A is a plan view showing the arrangement of the operating members used on the pallet drainage device according to one embodiment of the present invention on the turning device, and FIG. 4B is a plan view of FIG. It is a CC line arrow line view.
[0036]
As shown in FIGS. 4A and 4B, the operating member 30 protrudes from an upper portion of the turning device 5. The operating member 30 is arranged to push the rear end of the lever 251 upward when the elevator 3 descends to the entrance / exit floor E and the pallet 2 is transferred from the elevator 3 to the upper part of the turning device 5. Is established. The operating member 30 is formed of a tapered plate-shaped body 30a, and a base end thereof is fixed to an upper portion of the turning device 5. Further, a cylindrical component 30b for easily abutting on the rear end of the lever 251 is attached to the front end of the plate 30a.
[0037]
Thereby, when the elevator 3 is lowered and the pallet 2 is placed on the upper part of the turning device 5, the cylindrical part 30 b raises the rear end of the lever 251 upward against the urging force of the urging member 254. Push up. As a result, the lever 251 is rotated about the axis of the connecting pin 252, and the drain 233a is lowered to the lower position together with the tip of the lever 251 to discharge the water in the roadway 20. This water is discharged to a drainage ditch (not shown) on the entrance / exit floor E.
[0038]
As a modified example of the above-described embodiment, the above-described pallet drainage device may be arranged in a space below both ends in the longitudinal direction of the ceiling plate 21 (see FIG. 5A). Of course, as described above, the pallet drainage device may be arranged in a space below the central portion in the longitudinal direction of the ceiling plate 21 as described above. Thereby, even if both ends in the longitudinal direction of the roadway 20 are bent, the water accumulated in the bottom portions 20a at both ends of the roadway 20 can be discharged without leaving. Note that the difference between this modified example and the above-described embodiment lies in the configuration of the operating member, and therefore the configuration of the operating member will be described here. In addition, parts that are the same as those in the above-described embodiments are given the same reference numerals, and detailed descriptions thereof are omitted.
[0039]
FIG. 5A is a side view showing the arrangement of the operating members when the pallet drainage device is provided in a space below both ends in the longitudinal direction of the pallet ceiling plate, and FIG. It is a figure showing composition of an operation member.
[0040]
The operating members 30 are provided at positions corresponding to the pallet drainage devices, respectively. Specifically, the operating member 30 is disposed so as to sandwich the elevator 3 and the turning device 5, and is installed on a mounting table 40 erected on the floor in the pit 6. The height of the mounting table 40 is appropriately set according to the operation range of the operation member 30.
[0041]
As shown in FIG. 5B, the operating member 30 includes a first arm 31 that pushes the rear end of the lever 251 upward. The first arm 31 has a long plate shape, and a central portion thereof is installed on a moving device 32 that moves the first arm 31 in the vertical direction. The moving device 32 is installed on the mounting table 40, and includes a motor 32a and a long plate-shaped second arm 32b driven by the motor 32a. The second arm 32b is configured such that the distal end thereof rotates vertically upward (in the direction of the arrow R in FIG. 5B) from the horizontal direction about the base end thereof by driving the motor 32a. The distal end of the second arm 32b is in contact with the center of the first arm 31. Therefore, when the distal end of the second arm 32b is moved in the vertical direction by the motor 32a, the center of the first arm 31 is also moved in the vertical direction.
[0042]
One end of the first arm 31 pushes the rear end of the lever 251 upward when the moving device 32 pushes the center of the first arm 31 upward. The other end of the first arm 31 is not fixed on the mounting table 40, and a weight 33 having a weight set so as to oppose a force for pushing the lever 251 upward is suspended. Therefore, the weight 33 is positioned on the mounting table 40 by its own weight, except in a special case where a pallet 2 described later tilts or bends and an excessive force acts on one end of the first arm 31. It has become.
[0043]
In the above configuration, the center portion of the first arm 31 is pushed upward by rotating the tip end of the second arm 32b vertically upward. However, since the weight 33 is suspended from the other end of the first arm 31, the other end of the first arm 31 is not displaced. As a result, one end of the first arm 31 rises with the other end of the first arm 31 as a fulcrum. As a result, the rear end of the lever 251 is pushed upward. As a result, the distal end of the lever 251 and the drainage section (not shown) of the drainage hose descend to the lower position, and the water accumulated in the roadway 20 is discharged to the outside.
[0044]
Further, when the pallet 2 is tilted or bent and an excessive force acts on one end of the first arm 31 from the lower surface of the pallet 2, the one end of the first arm 31 is moved downward (see FIG. 5B). The pallet 2 is lowered by an amount Z corresponding to the inclination or deflection of the pallet 2 in the direction of the arrow Y1). As a result, the other end of the first arm 31 is rotated about the contact point between the first arm 31 and the second arm 32b as a fulcrum, and the weight 33 suspended on the other end of the first arm 31 is moved upward ( 5 (b) (in the direction of arrow Y2). Thereby, it is possible to prevent the operation member 30 from receiving an excessive force from the pallet 2.
[0045]
Furthermore, a pallet drainage device according to another modified example different from the above-described embodiment and modified examples of the present invention will be described with reference to FIGS. This pallet drainage device can also be applied to a parallel multi-story parking facility in which the parking tower 10 shown in FIG. The details will be described later. Note that the same reference numerals are given to the same components as those in the above-described embodiment, and the detailed description is omitted.
[0046]
FIG. 6 is a plan view showing an arrangement of an elevator, a turning device, and an elevating deck for elevating and lowering a pallet in a parallel-type multi-story parking facility. FIG. 6A shows a case where a vehicle passes over the elevating deck, and FIG. Indicates a case where the pallet is placed on the lifting deck. FIG. 7 is a view taken along line DD in FIG. 6B. 8 is a side view of the operating member mounted on the elevating deck, as viewed in the direction of arrows EE in FIG. 6B.
[0047]
As shown in FIGS. 6 (a) and 6 (b), on the entrance / exit floor E of the tandem multi-story parking facility, two rooms for entering / exiting the vehicle M are provided in series. As shown in the figure, a pit 6 is provided in the room on the entrance side, and a turning device 5 for turning the pallet 2 is provided upright on the floor in the pit 6.
[0048]
The elevator 3 includes a deck 3a on which the pallet 2 is placed. An opening 3b into which the turning device 5 is loosely inserted is provided in the center of the deck 3a. Then, when the elevator 3 descends to the entrance / exit floor E, the deck 3a descends so that the turning device 5 is loosely inserted into the opening 3b. At this time, the pallet 2 is transferred from the elevator 3 to the turning device 5.
[0049]
Elevating decks 50 that can move up and down in the vertical direction are provided on both sides of the elevator 3. The elevating deck 50 is for forming a vehicle passageway to the back room together with the deck 3a and the turning device 5 in the entrance room when the vehicle M enters the back room.

At the other end of the wire 63a, a rod 63b having an enlarged diameter is fixed to the third arm 61 with its distal end directed downward to limit the amount of projection of the third arm 61 from the mounting surface 51. The portion of the rod 63a whose diameter is not expanded is loosely inserted into a through hole 56 provided in a frame 55 below the lifting deck 50. The outer diameter of the expanded end of the rod 63b is set to be larger than the inner diameter of the through hole 56 so that the end of the rod 63b does not pass through the through hole 56. The frame 55 is fixed to a predetermined place without interlocking with the elevation of the mounting surface 51. That is, the position of the through hole 56 is fixed. This position is set such that the tip of the rod 63b is caught in the through hole 56 while the mounting surface 51 of the elevating deck 51 is rising from the second setting position to the third setting position.
[0057]
One end of an urging member 62 for urging the third arm 61 displaced downward to return to the original position is attached to an end of the L-shaped short side portion of the third arm 61. Have been. The biasing member 62 is made of a spring or the like. The other end of the urging member 62 is attached to a support portion 54 extending horizontally from a lower portion of the frame 53 on the upper part of the elevating deck 50. The urging means 62 expands and contracts upward with the support portion 54 as a base point. Both the frame 53 and the support portion 54 are attached to a portion of the elevating deck 50 that moves up and down. Therefore, the urging means 62 is not expanded or contracted by the elevating operation of the elevating deck 50.
[0058]
In the above configuration, when the pallet 2 turns as shown in FIG. 8A, the mounting surface 51 of the lifting deck 50 is at the first set position below the entry surface of the vehicle M. Thereafter, when the pallet 2 abuts on the mounting surface 51 of the lifting deck 50 raised to the second set position, the L-shaped corner of the third arm 61 abuts on the rear end of the lever 251 and the lever 251 is moved. Push the rear end upward. Then, the tip of the lever 251 is displaced downward. As a result, the drain 233a connected to the tip of the lever 251 is also displaced downward to the lower position in conjunction therewith, and the water accumulated in the lane 20 is discharged from the drain 233a. Further, when the elevating deck 50 is lowered to the first set position (the position in the state shown in FIG. 8A), the urging member of the lever 251 causes the drain portion 233a to rise to the original upper position. Further, when the elevating deck 50 rises to the third set position, the tip of the rod 63b is caught in the through hole 56, and the rod 63b pulls the third arm 61 downward through the wire 63a. Accordingly, the urging member 62 is compressed, and the amount of protrusion of the third arm 61 from the mounting surface 51 is suppressed to a predetermined amount. When the elevating deck 50 is lowered from this state, the amount of protrusion of the third arm 61 from the mounting surface 51 is returned to the original position by the urging member 62.
