  A horizontal circulation parking apparatus is usually provided with a cage. The cage moves up and down between a berth in which a vehicle enters and exits and a storage unit in which the vehicle is stored. The cage is horizontally suspended by a plurality of (for example, four) string-like members (chains or wires), and is moved up and down along the hoistway by moving the plurality of string-like members up and down in synchronization with a lifting drive.

  However, the amount of elongation of each string-like member varies depending on the presence or absence of the vehicle, the size of the vehicle weight, the unbalanced load by the vehicle, and the like.

FIG. 1 is a side view (A) and a plan view (B) showing an example of the horizontal circulation parking apparatus of the present invention.
A horizontal circulation parking device (hereinafter simply referred to as “parking device”) is a mechanical parking device that moves a pallet 2 on which a vehicle 1 is placed in a horizontal plane to enter and exit the vehicle 1 (incoming and outgoing). .
The vehicle 1 is, for example, a passenger car. The vehicle 1 is a small car, a medium car, a large car, a high roof car, or the like.

1 (A) and 1 (B), the parking apparatus is an underground type, and has two upper and lower storage areas in the basement. Moreover, the lift 3 which raises / lowers vertically between the storage part on the ground and the upper stage and the lower stage of the underground, and raises / lowers the pallet 2 between them is provided.
In this example, each of the upper and lower two stages (each storage area) has a vehicle storage space for 12 vehicles in a range other than the position where the lift 3 moves up and down the pallet 2.

  In this figure, a drive cell 4 is provided in each vehicle storage space. In this example, the lift 3 is also provided with a drive cell 4. The drive cell 4 moves the pallet 2 on which the vehicle 1 is placed in the width direction and the length direction.

  The drive cell 4 is configured to be capable of both “lateral feed” for moving the pallet 2 on which the vehicle 1 is placed in the width direction and “vertical feed” for moving in the length direction.

In FIG. 1, one drive cell 4 is provided in each of the two upper and lower stages in the vehicle storage space for 12 cars in this example. Each drive cell 4 has a frame 10 (see FIG. 4) corresponding to the size of the pallet 2 in plan view.
In each of the upper and lower two stages, the plurality of frames 10 are arranged at a fixed interval from each other, and are supported horizontally at the four corners. In each stage, the pallet 2 is not placed on at least one drive cell 4, and the pallet 2 is placed on the other drive cells 4. The drive cell 4 on which the pallet 2 is not mounted is hereinafter referred to as “empty cell”.

Since at least one drive cell 4 is an empty cell in each stage due to the configuration of the parking device described above, the pallet 2 on the drive cell 4 adjacent to the empty cell is moved horizontally (horizontal feed or vertical feed) onto the empty cell. can do. By this horizontal movement, the position of the empty cell moves to an adjacent position.
Therefore, by repeating this, the pallet 2 at each stage can be freely moved horizontally (transverse feed or vertical feed).

  FIG. 2 is an operation explanatory diagram of the above-described horizontal circulation parking device (parking device). In this figure, 5 indicates a lift position.

In FIG. 2, the vehicle 1 indicated by the symbol a (hereinafter referred to as the vehicle a) is moved horizontally to the lift position 5 in the order of (A), (B), (C), and (D), and the lift 3 is used to enter and exit the ground. The operation | movement which conveys to a part is shown.
As shown in this figure, the horizontal movement of the pallet 2 in this parking apparatus determines the shortest loading / unloading route by computer control, efficiently moves the vehicle 1 from one to the next like a puzzle, Realizes waiting time for loading and unloading.

FIG. 3 is a bottom view showing the bottom surface of the pallet 2.
The pallet 2 is set to a size such that the entire vehicle 1 (for example, a passenger car) is placed on the pallet 2 and a part of the vehicle 1 does not come out in a plan view of the pallet 2. The size of the pallet 2 is, for example, about 2000 to 2100 mm in width and about 5300 to 5500 mm in length.

  3, the pallet 2 has a pair of width direction rails 6a, a pair of length direction rails 6b, and a plurality (four in this example) of switching rails 6c on the lower surface thereof. Hereinafter, the width direction rail 6a, the length direction rail 6b, and the switching rail 6c are simply referred to as “rails 6” unless necessary.

The pair of width direction rails 6 a extend horizontally at a certain interval in the width direction of the pallet 2. In the following, “horizontal” means horizontal when the pallet 2 is in use.
The pair of longitudinal rails 6b extend horizontally at a certain interval in the longitudinal direction of the pallet 2. The distance between the pair of width direction rails 6a and the distance between the pair of length direction rails 6b are set so that the pallet 2 can be supported horizontally.

A plurality (four in this example) of switching rails 6c are provided at intersections 7 (four in this example) of the width direction rail 6a and the length direction rail 6b, and turn between the width direction and the length direction. It is configured to be possible.
The turning of the switching rail 6c is a free turning around the vertical axis, and no turning drive mechanism is provided, so that the switching rail 6c is freely turned by an external force.

The lower surfaces of the width direction rail 6a and the length direction rail 6b are flush with each other. The width direction rail 6a and the length direction rail 6b are set to have the same width.
The width-direction rail 6a and the length-direction rail 6b are divided at the intersection 7 and their respective end surfaces are spaced from the turning center of the switching rail 6c by a certain distance. The outer ends of the width direction rail 6 a and the length direction rail 6 b extend to the vicinity of the outer edge of the pallet 2.

  The switching rail 6c is a single rail having the same width as the width direction rail 6a and the length direction rail 6b. The lower surface of the switching rail 6c is a horizontal plane that is flush with the width direction rail 6a and the length direction rail 6b. Further, the length of the switching rail 6c is set so as to connect the width direction rail 6a and the length direction rail 6b divided at the intersection 7 via the switching rail 6c.

In FIG. 3, 8 is a reference position of the pallet 2. In this example, the reference position 8 is a center point in the width direction and the length direction of the pallet 2. The reference position 8 is not limited to this position, and may be another position.
The positions and intervals of the pair of width direction rails 6a and the pair of length direction rails 6b described above and the turning centers of the plurality of switching rails 6c are manufactured with a preset accuracy from the reference position 8.
For example, the distances L1 from the reference position 8 to the center line of the width direction rail 6a are each 950 mm, and the distances L2 from the reference position 8 to the center line of the length direction rail 6b are each 390 mm. The turning center of the switching rail 6c is set at the intersection of the center line of the width direction rail 6a and the center line of the length direction rail 6b. The positioning accuracy of the distances L1 and L2 is about −0.5 mm to +0.5 mm.

With the configuration of the pallet 2 described above, the width of the pallet 2 is adjusted by the width direction rail 6a and the switching rail 6c by turning the switching rail 6c horizontally and connecting the width direction rail 6a separated via the switching rail 6c. A pair of rails extending in the entire direction can be constructed.
In this case, since the width direction rail 6a and the switching rail 6c of the pallet 2 are manufactured with a preset accuracy from the reference position 8, the width direction rail 6a and the switching rail 6c are driven by the drive cell 4 as a pair of rails. By doing so, the pallet 2 can be moved horizontally in the width direction.

Similarly, by turning the switching rail 6c horizontally and connecting the longitudinal rails 6b separated through the switching rail 6c, the longitudinal direction of the pallet 2 is achieved by the longitudinal rail 6b and the switching rail 6c. A pair of rails extending entirely can be constructed.
In this case, since the length direction rail 6b and the switching rail 6c are manufactured with the accuracy set in advance from the reference position 8, the length direction rail 6b and the switching rail 6c are driven by the drive cell 4 as a pair of rails. Thus, the pallet 2 can be horizontally moved in the length direction.

FIG. 4 is a plan view of the drive cell 4.
In this figure, the drive cell 4 includes a frame 10 and a pallet drive device 20 installed on the frame.

The frame 10 is a structural frame of the driving cell 4.
In FIG. 4, the frame 10 includes a single outer frame 12 and a pair of inner frames 16.
The single outer frame frame 12 is a rectangular member in plan view that extends along the outer edge of the pallet 2. The size of the outer frame 12 corresponds to the pallet 2 in plan view, and has a width of about 2000 to 2100 mm and a length of about 5300 to 5500 mm, for example.
The pair of inner frames 16 extends in the width direction of the pallet 2, and both ends are supported by the outer frame frame 12.

  In FIG. 4, the plurality of frames 10 are arranged at regular intervals and are supported horizontally at the four corners. In this case, pillars C extending vertically are provided outside the four corners of the frame 10 so that the pallet 2 can pass between the pillars C by moving horizontally in the width direction and the length direction.

The pallet drive device 20 includes a pair of drive units 22, a pair of driven units 24, and a turning mechanism 26.
The pair of drive units 22 and the pair of driven units 24 are provided at the turning center positions of the four switching rails 6c of the pallet 2, and are attached so as to freely turn around the turning center of the switching rail 6c. ing. In this example, a pair of drive units 22 and a pair of driven units 24 are arranged at diagonal positions among the four turning centers of the switching rail 6c.

The turning mechanism 26 includes a plurality of interlocking rods 27a in which a pair of drive units 22 and a pair of driven units 24 are sequentially connected, and a turning drive unit 27b that moves the interlocking rods 27a horizontally.
With this configuration, the turning drive unit 27b causes the drive unit 22 and the driven unit 24 to turn horizontally in synchronization with each other via the interlocking rod 27a, and the drive direction and the guide direction are set in the width direction (for lateral feed) and the length direction. It can be switched between (for vertical feed).

FIG. 5 is a side view (A) and a plan view (B) of the drive unit 22.
As shown in this figure, the drive unit 22 has drive wheels 22a that support and drive the pallet 2, and a plurality (four in this example) of guide rollers 22b that guide the pallet 2.
The drive wheel 22a is rotationally driven around a horizontal axis by a drive motor 23 fixed to the unit body 21. The drive wheel 22a has a disk shape, and supports the lower surface of the rail 6 of the pallet 2 on the outer peripheral upper surface thereof, and drives the pallet 2 in the horizontal direction by its rotation.

A plurality (four in this example) of guide rollers 22b are attached to the upper portion of the unit main body 21 so as to be freely rotatable around a vertical axis. The guide roller 22b is cylindrical. The four guide rollers 22b are arranged two by two across the lower side surface of the rail 6 of the pallet 2, and guide the pallet 2 in the horizontal direction therebetween.
Further, the intervals in the feed direction of the rails 6 of the four guide rollers 22b are set shorter than the length of the switching rail 6c.
With this configuration, by turning the four guide rollers 22b horizontally with the four guide rollers 22b sandwiching the switch rail 6c, the switch rail 6c is moved in the width direction (for lateral feed) and in the length direction (vertical). Can be switched between (for feeding).

  In FIG. 5, the unit main body 21 further includes a turning shaft 21a and an interlocking member 21b.

The turning shaft 21a is a shaft extending vertically downward, and is attached to a bearing 28 attached to the inner frame 16 so as to be freely rotatable around the vertical axis. This rotation center is the turning center position of the switching rail 6c. The bearing 28 is a double ball bearing in this example, but may be other bearings.
The interlocking member 21b projects outward from the turning shaft 21a, and has an interlocking roller 22c attached to the interlocking rod 27a so as to be rotatable at an outer end thereof.

  In the driven unit 24, the drive wheel 22a of the drive unit 22 described above is replaced with a driven wheel 24a, and the drive motor 23 is omitted. Other configurations are the same as those of the drive unit 22.

With the configuration described above, the drive direction of the drive unit 22 and the guide direction of the driven unit 24 can be switched in conjunction with the width direction and the length direction by the interlocking rod 27a.
Further, when the rails 6 constitute a pair of rails in the width direction or the length direction, the pair of drive units 22 are positioned on the pair of rails, and the pallet is arranged via the pair of rails. 2 and the pallet 2 can be horizontally driven in the width direction or the length direction.
Furthermore, in this case, the pair of driven units 24 can also be positioned on the pair of rails, support the pallet 2 via the pair of rails, and guide the pallet 2 in the width direction or the length direction. .
Therefore, the pallet 2 on which the vehicle 1 is mounted can be switched between the lateral feed moving in the width direction and the vertical feed moving in the length direction by the pallet driving device 20 described above.

6 is a view taken in the direction of arrows AA in FIG. This figure is a plan view of a loading / unloading section where the vehicle 1 loads / unloads.
In the present invention, the lift 3 includes a cage 30, an elevating frame 40, and an elevating drive device 50 (not shown, see FIG. 8).
The cage 30 is configured such that a pallet 2 (indicated by a two-dot chain line) on which a vehicle 1 (not shown) is placed can be raised and lowered along a hoistway.
The elevating frame 40 has four lift main pillars 42 surrounding the four corners of the cage 30 in plan view.

In FIG. 6, the entrance / exit part is provided with a berth BS where a person gets on and off the vehicle 1 and an intermediate part MS located between the cage 30 and the berth BS.
The pallet drive device 20 shown in FIG. 4 is installed in the cage 30, the intermediate part MS, and the berth BS so that the pallet 2 on which the vehicle 1 is placed can be moved horizontally between the berth BS and the lift 3. It has become.

  In this example, the pallet driving device 20 of the cage 30 and the intermediate part MS can perform only horizontal feeding, and the pallet driving device 20 of the berth BS can perform both horizontal feeding and vertical feeding. However, the present invention is not limited to this configuration, and both the lateral feed and the longitudinal feed can be performed in the cage 30, or only the lateral feed can be performed in the berth BS.

  Furthermore, the movable part F which raises / lowers without interfering with the pallet drive device 20 is provided in the intermediate part MS. The movable floor F is located at the same height as the pallet 2 when a person gets on and off the vehicle 1, and retracts downward when the pallet 2 moves horizontally between the berth BS and the lift 3.

With the configuration described above, the vehicle 1 that has been received from the outside on the pallet 2 of the berth BS can be horizontally moved to the top of the cage 30 of the lift 3 by the plurality of pallet driving devices 20 in the storage / exit section.
Similarly, the pallet 2 placed on the cage 30 can be horizontally moved to the berth BS by the plurality of pallet driving devices 20, and the vehicle 1 placed on the pallet 2 can be discharged outside from the berth BS.
In this horizontal movement, the cage 30 needs to be positioned at a predetermined height of the loading / unloading unit. This predetermined height is a height at which the pallet 2 on the cage coincides with the pallet 2 on the berth.

  FIG. 7 is an explanatory view showing the difference between the guide rail GR of the conventional elevator parking apparatus and the lift main column 42 of the present invention.

  As shown in FIG. 7A, in the conventional elevator parking apparatus, in addition to the structural frame MF that supports the entire apparatus, four guide rails GR that extend vertically to the outside of the cage K in a plan view are provided. The cage K moves up and down along the guide rail GR.

Further, in this drawing, the counterweight CW is connected to the cage K via a plurality of string-like members (for example, chains) so as to reduce the load on the lifting drive.
Further, the blown-out space H indicated by hatching in the drawing is a space for passing cables and sensors that move up and down with the cage K when the cage K moves up and down.

In FIG. 7A, the guide rail GR (for example, H-shaped steel) can be set at a free position in consideration of the position of the counterweight CW and the blowout space H. The guide rails GR are independently fixed to the structural frame MF, and a guide surface (for example, an inner surface of H-shaped steel) is provided over the entire lifting range of the cage K. Furthermore, the support member of the cage support device (not shown) described above is attached to the outer surface of the guide rail GR.
In the conventional elevator type parking apparatus, the guide rail GR also serves as a support frame for the storage rack R adjacent to the left and right in the drawing of the cage K.

On the other hand, as shown in FIG. 7B, the lift 3 of the horizontal circulation parking apparatus has a plurality of (for example, four) lift main pillars provided on the outside in the vicinity of the cage 30 in plan view. Reference numeral 42 denotes a structural frame, on which an elevating drive device 50 (not shown, see FIG. 8) is installed.
The lift main pillar 42 (for example, H-shaped steel) of the horizontal circulation parking apparatus is installed as a structural frame, for example, standing in a building, and the adjacent lift main pillars are horizontal members or slanted so as to withstand horizontal loads such as earthquakes. The members are connected to each other.
For this reason, the lift main column 42 of the horizontal circulation parking apparatus has a horizontal member or an oblique member fixed at a plurality of locations, so there is no guide surface over the entire lifting range of the cage 30 and the support member of the cage support device is used. Can not be provided.

In order to use the inner surface of the lift main column 42 (for example, H-shaped steel) as a guide surface over the entire lifting range, it is theoretically fixed to the outer surface of the lift main column 42 while being shifted from the axis. Is possible. However, in this case, since the rigidity of the entire structural frame is lowered, it is necessary to increase the strength of each member as compared with the conventional case, and there is a problem that the amount of steel material used is significantly increased.
The present invention has been developed to solve the above-described problems.

  FIG. 8 is a side view of the lift 3 taken along the line B-B in FIG. 6. FIG. 9 is a front view of the lift 3 taken along the line CC of FIG.

  8 and 9, the lifting frame 40 includes an upper main beam 44, a horizontal support beam 46, and a diagonal member 48 in addition to the four lift main columns 42 described above.

The lift main pillar 42 is H-shaped steel in this example, and the lower end thereof is fixed to the floor surface of the underground storage area and extends vertically to the above-ground storage / exit section. In addition, you may connect in the middle as needed.
The upper main beam 44 connects the upper ends of the four lift main pillars 42 to each other in the upper part of the entry / exit portion on the ground, and the lift main pillar 42 and the upper main beam 44 form a hollow rectangular parallelepiped frame. The internal space of this rectangular parallelepiped frame becomes a hoistway in which the cage 30 moves up and down.

  The horizontal support beam 46 horizontally connects the centers of two adjacent lift main columns 42 via a bracket fixed to the lift main column 42 outside the hoistway. That is, the connecting portions of the lift main column 42 and the horizontal support beam 46 are connected by welding or bolts so that their respective axes coincide with each other and force (axial force or bending moment) can be smoothly transmitted from one to the other. It is good to do.

  The diagonal member 48 obliquely connects the adjacent lift main column 42 and the horizontal support beam 46 via a bracket fixed to the lift main column 42 or the horizontal support beam 46 outside the hoistway.

  With the structure of the lifting frame 40 described above, the rigidity of the lifting frame 40 can be increased so as to withstand horizontal loads such as earthquakes, and the entire structure frame can be installed independently in the building. In this case, a horizontal support member that transmits a horizontal load may be provided between the internal beams of the building.

  8 and 9, the horizontal support beam 46 includes a length direction support beam 46a and a width direction support beam 46b.

  The length direction support beam 46a horizontally connects two of the four lift main columns 42 adjacent to each other in the length direction of the pallet 2. In this example, the longitudinal support beam 46a and the diagonal member (not shown) in the longitudinal direction are at a height (incoming / outgoing part and storage area) where the pallet 2 carrying the vehicle 1 is laterally fed in the width direction. It is provided at a position where it does not interfere with the vehicle 1 and the pallet 2.

  The width direction support beam 46b horizontally connects two of the four lift main columns 42 adjacent to each other in the width direction of the pallet 2. In this example, the pallet 2 on which the vehicle 1 is mounted is not vertically fed from the cage 30, so the two lift main columns 42 adjacent in the width direction are installed at arbitrary positions as long as the necessary strength (rigidity) is satisfied. be able to. The same applies to the diagonal member 48 in the width direction between the two lift main columns 42 adjacent in the width direction.

In the present invention, a part of the supporting beams 46b in the width direction is used as the landing beams 49 that support the movable legs 62 of the landing device 60 described later.
The landing beam 49 is different from the width-direction support beam 46b in that its upper surface position is determined in accordance with a predetermined stop height of the cage 30, but the other points are the same. That is, the landing beam 49 also functions as the width direction support beam 46b. Therefore, even if the landing beam 49 is provided, the amount of steel used is substantially the same as before.

  In addition, this invention is not limited to this structure, You may provide the landing beam 49 in addition to the width direction support beam 46b. In this case, the landing beam 49 only needs to have a function of supporting the movable leg 62, and can be lighter than the width direction support beam 46b.

8 and 9, the lift drive device 50 is provided on the top of the lift frame 40 and hangs the cage 30 to drive it up and down.
In this example, the lift drive device 50 includes a flexible string-like member 52 and a lift drive mechanism 54.

The flexible string-like member 52 is, for example, a chain or a wire. In this example, the lower ends of the four string-like members 52 are attached to the four corners in a plan view of the cage 30, and the cage 30 is suspended horizontally.

The lower support part 36 moves up and down by placing an empty pallet 2 on which the vehicle 1 is not placed.
Hereinafter, the pallet 2 on which the vehicle 1 is placed is referred to as “actual pallet 2a”, and the empty pallet 2 on which the vehicle 1 is not placed is referred to as “empty pallet 2b”. Note that both are simply referred to as “pallet 2” unless otherwise required.

With the configuration of the cage 30 described above, immediately after the actual vehicle pallet 2a is horizontally moved from the berth BS to the upper support portion 34 in the loading / unloading portion at the time of continuous warehousing, the cage 30 is temporarily raised to empty the pallet 2b of the lower support portion 36. Can be moved horizontally to the berth BS. By this warehousing operation, the vehicle 1 can be admitted to the berth BS in parallel with the storage of the actual vehicle pallet 2a, and the waiting time during continuous warehousing can be shortened.
Further, due to the configuration of the cage 30 described above, immediately after the empty pallet 2b of the berth BS is horizontally moved to the lower support portion 36 in the loading / unloading portion, the cage 30 is once lowered to support the upper portion of the actual vehicle pallet 2a. The part 34 can be moved horizontally to the berth BS. By this delivery operation, the vehicle 1 can be delivered from the berth BS in parallel with the storage of the empty pallet 2b, and the waiting time during continuous delivery can be shortened.

In FIG. 8, the mechanical parking device of the present invention further includes a landing device 60.
The landing device 60 is provided on the cage 30 and has movable movable legs 62 that can support the weight of the cage 30 with landing beams 49 at a predetermined stop height of the cage 30.
In this figure, the landing device 60 includes a first landing device 60A and a second landing device 60B provided at both ends of the cage 30 in the length direction.

FIG. 10 is an enlarged view of the landing device 60, (A) is an enlarged view of a D portion of FIG. 8, and (B) is an enlarged view of an E portion of FIG.
As shown in FIG. 6, the elevating frame 40 has a blowout space H adjacent to one end in the longitudinal direction of the cage 30 in the elevating range of the cage 30. The blowout space H is a space for passing cables and sensors that move up and down with the cage 30 when the cage 30 moves up and down.

  6 and 10A, the cage 30 is provided on the outer side in the width direction of the blow-out space H in the plan view, and outward to a position close to the horizontal support beam 46 (the width direction support beam 46b and the landing beam 49). An extending portion 38 is provided.

In FIG. 10A, the movable leg 62 of the first landing device 60A is fixed to the lower surface of the overhanging portion 38 so as to be swingable about the horizontal rotation shaft 63. The movable leg 62 includes a first leg portion 62 a extending downward from the horizontal rotation shaft 63 and a second leg portion 62 b extending inward from the horizontal rotation shaft 63. The first leg portion 62a and the second leg portion 62b are preferably an integral part.
The movable leg 62 swings between the protruding position and the retracted position so as to be able to appear and retract. At the protruding position, the first leg 62 a swings to the outside from the overhanging portion 38, and the lower end of the first leg 62 a is supported by the upper surface of the landing beam 49. In the retracted position, the first leg portion 62 a swings inward from the overhanging portion 38 and retracts inside the overhanging portion 38.
In order to adjust the support height of the movable leg 62, that is, the stop height of the cage 30, a support plate 49 a is preferably fixed to the upper surface of the landing beam 49. The support plate 49a is preferably detachable from the upper surface of the landing beam 49.

The landing device 60 further includes a leg driving device 64 that moves the movable leg 62 between the protruding position and the retracted position. In FIG. 10A, the leg driving device 64 of the first landing device 60A includes a reduction gear-equipped motor 64a and a power transmission mechanism 64b that transmits the output of the reduction gear-equipped motor 64a to the horizontal rotation shaft 63. The power transmission mechanism 64b is a chain and a sprocket in this example, but may have other configurations.
With this configuration, the movable leg 62 can be moved between the projecting position and the retracted position by the speed reducer-equipped motor 64a.
When moving from the protruding position to the retracted position, it is preferable to raise the cage 30 once so that the lower end of the first leg portion 62a does not interfere with the landing beam 49.

In FIG. 10A, the landing device 60 further includes a locking fitting 65 fixed to the overhanging portion 38. The locking metal fitting 65 abuts on the lower surface of the second leg portion 62 b at the protruding position, and transmits a downward force due to a rotational moment acting on the movable leg 62 to the overhang portion 38.
With this configuration, when the weight of the cage 30 is supported by the horizontal support beam 46 at the height at which the cage 30 is stopped, the rotational moment acting on the movable leg 62 can be supported by the locking metal fitting 65. 64 loads (for example, brake capacity) can be reduced.

FIG. 11 is a view taken along the line FF in FIG.
In this figure, the cage 30 further includes a horizontal connecting portion 39 that horizontally connects the two suspended portions 32 on the counterweight CW side. In this example, the horizontal connecting portion 39 includes a pair of first connecting portions 39a directly fixed to the suspension portion 32 and a second connecting portion 39b that horizontally connects the pair of first connecting portions 39a.

  In FIG. 10B, the movable leg 62 of the second landing device 60B is fixed to the lower surface of the first connecting portion 39a so as to be swingable about the horizontal rotation shaft 63. The structure of the movable leg 62 and the locking metal fitting 65 is the same as that of the first landing device 60A shown in FIG.

In FIG. 11, the horizontal rotating shafts 63 of the pair of movable legs 62 of the second landing device 60B are connected to each other. The leg drive device 64 includes a reduction gear-equipped motor 64 a and a power transmission mechanism 64 b that transmits the output of the reduction gear-equipped motor 64 a to the horizontal rotation shaft 63. The power transmission mechanism 64b is a chain and a sprocket in this example, but may have other configurations.
With this configuration, the movable leg 62 can be moved between the projecting position and the retracted position by the speed reducer-equipped motor 64a.
Note that when moving from the protruding position to the retracted position, the cage 30 is temporarily raised so that the lower end of the first leg portion 62a does not interfere with the landing beam 49, as in the first landing device 60A. is there.

In FIG. 11, the elevating drive device 50 further includes a loosening prevention mechanism 56 that prevents the string-like member 52 from loosening.
The cage 30 has a lifting plate 33 on the upper portion of the hanging portion 32. The lifting plate 33 has a vertical hole 33a through which the lower connecting portion 52a of the string-like member 52 passes vertically. In this example, the lower connecting part 52a is formed of a solid round bar, and an enlarged diameter part 52b having a diameter larger than that of the lower connecting part 52a and the vertical hole 33a is fixed to the lower end of the lower connecting part 52a.

  In this example, the loosening prevention mechanism 56 includes a compression spring 56a and a guide tube 56b. The compression spring 56 a is sandwiched between the lower end portion (the enlarged diameter portion 52 b) of the string-like member 52 and the lower surface of the lifting plate 33, and biases the enlarged diameter portion 52 b downward with respect to the lifting plate 33. The guide tube 56b is a hollow tube whose upper end is fixed to the lifting plate 33. The compression tube 56b is accommodated inside the guide tube 56b and guides its expansion and contraction.

  With the above-described configuration of the slack prevention mechanism 56, the slack (or slack) generated in the string-like member 52 when the cage 30 is supported by the landing beam 49 at the height at which the cage 30 is stopped by the landing device 60 is compressed. Absorption can be achieved by the extension of the spring 56a.

6 and 9, the mechanical parking apparatus of the present invention further includes an elevating guide rail 57.
The elevating guide rail 57 is an H-shaped steel in this example, is attached by dividing the width direction support beam 46b in the middle of the horizontal support beam 46 (width direction support beam 46b), and extends vertically over the entire elevating range of the cage 30. .

  That is, in this example, the landing beam 49 is placed between the lift main column 42 and the lifting guide rail 57 of the cage 30 so that the space occupied by the lift 3 and the amount of steel used are not significantly increased compared to the conventional lift structure. The horizontal support beam 46 having a conventional structure is also used.

  Also, in order to disperse the horizontal load that the lifting guide rail 57 receives from the cage side when an earthquake occurs, the landing beam 49 is assumed to have sufficient strength to withstand the vertical load at the time of landing. It is installed in a strong direction.

  Further, the landing beam 49 needs to be passed between the lift main pillars 42 at the four corners with different directions and the lifting guide rail 57, and it is necessary to secure the vertical and horizontal strength while securing the adjustment allowance at the time of assembly. Therefore, these joint portions are reinforced in the horizontal direction by taking out a receiving material for placing the landing beam 49 from the column side, receiving a load in the vertical direction, and joining the side surfaces with plates. Assembling is a structure that connects with bolt material, and the assembly adjustment allowance for the bolt hole is secured.

  The elevating guide rail 57 may be provided with, for example, channel steel inside without dividing the width direction support beam 46b.

6 and 11, the mechanical parking apparatus of the present invention further includes a lifting guide roller 58.
The elevating guide rollers 58 are attached to both ends of the cage 30 in the length direction, and guide the cage 30 along the elevating guide rails 57.

FIG. 12 is a configuration diagram of the lifting guide roller 58. In this figure, (A) is an enlarged view of part G in FIG. 11, and (B) is a side view of (A).
As shown in this figure, the elevating guide roller 58 includes a pair of free rollers 58a and 58b that freely rotate around horizontal axes that are orthogonal to each other.
In the drawing, the upper free roller 58a rotates around the horizontal axis in the longitudinal direction of the cage 30 and moves along the inner surface in the width direction of the lifting guide rail 57 (for example, H-shaped steel). Positioning.
Further, in the drawing, the lower free roller 58b rotates around the horizontal axis in the width direction of the cage 30 and moves along the inner surface in the vertical direction of the lifting guide rail 57 (for example, H-shaped steel). Position the direction position.
In addition, the structure of the raising / lowering guide roller 58 is not limited to this example, Other structures may be sufficient as long as the raising / lowering of the cage 30 can be guided and the position in the width direction and the position in the vertical direction can be positioned.

  The raising / lowering guide rail 57 and the raising / lowering guide roller 58 described above can guide the raising / lowering of the cage 30 and the position in the width direction and the longitudinal direction thereof can be significantly reduced.

The landing device 60 described above operates as follows.
(1) The pallet 2 and the vehicle 1 can be moved in the width direction between the berth BS and the cage 30 on the lift 3 by the pallet driving device 20.
The movable floor F retreats downward when the pallet 2 moves between the berth BS and the cage 30 on the lift 3.
(2) The cage 30 is moved up and down by the lift drive device 50, and the counterweight CW is moved up and down in the opposite direction to the cage 30. When the cage 30 is raised and lowered, the movable leg 62 of the landing device 60 is held in the retracted position.
(3) When the cage 30 stops at a predetermined level, the movable leg 62 of the landing device 60 is taken out of the cage 30 and landed on the landing beam 49 while being decelerated by the inverter-controlled lift drive device 50. . That is, before the cage 30 moves up and down and stops on the destination floor, the movable leg 62 is moved to the protruding position on the destination floor, and the cage 30 is lowered to land on the landing beam 49 on the destination floor. .
(4) When the tension of the string-like member 52 (for example, chain) loosens simultaneously with the landing of the cage 30 and falls below the spring force of the compression spring 56a, the compression spring 56a extends and reaches the free length of the compression spring 56a. A tension is applied to the string-like member 52 by the spring force.
(5) When the cage 30 shifts from the stop to the raising / lowering operation, the cage 30 is temporarily raised and the movable leg 62 of the landing device 60 is folded inside the cage 30. That is, when the cage 30 moves, the cage 30 is once raised, and the movable leg 62 is moved to the retracted position and held.

The mechanical parking apparatus of the present invention described above has the following effects.
(1) The pallet 2 can be conveyed without being affected by the extension of the string-like member 52 (for example, a chain) or the deviation of the stop height.
(2) When the cage 30 is landed at a predetermined height by the landing device 60, the plane displacement of the cage 30 can be corrected.
(3) By causing the cage 30 to be landed, it is possible to prevent the plane displacement of the cage 30 due to the conveyance reaction force.
Therefore, the swing when the vehicle 1 and the pallet 2 are transferred to the cage 30 is reduced and stabilized.

  As described above, according to the configuration of the present invention, the landing beam 49 that horizontally connects the two adjacent lift main pillars 42 and the landing device 60 provided in the cage 30 are provided. The landing device 60 has a movable leg 62 that can be moved in and out, and the weight of the cage 30 is supported by the landing beam 49 by the movable leg 62 at the stop height of the cage 30. Therefore, it is possible to eliminate the influence of the extension amount of the string-like member 52 due to the presence or absence of the vehicle 1, the size of the vehicle weight, or the uneven load by the vehicle 1. Therefore, the change in the stopping height of the cage 30, the inclination of the cage 30, and the swing of the cage 30 due to the extension amount of the string-like member 52 can be prevented.

  Further, since the weight of the cage 30 is supported by the landing beam 49 by the movable leg 62, the lift main column 42 is a structural frame, and even when horizontal members or diagonal members are fixed to a plurality of locations of the lift main column 42, the lift There is no need to provide a separate support member for the main column 42.

Although the horizontal circulation parking apparatus has been described in the above-described embodiment, the present invention is not limited to the horizontal circulation parking apparatus, and may be other mechanical parking apparatuses.
Further, the landing device 60 can be rotated in a horizontal plane or in a horizontal straight movement instead of in a vertical plane. Alternatively, a method may be used in which a lifting process is performed on the lifting guide rail 57 of the lifting frame 40 and a landing pin is inserted from the cage side to lock.
