  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the parking device has a parking device 1, 2 on multiple floors, or a lift device 4 that moves the parked vehicle 3 because the floors of the entrance and the parking space 2 are different. . The lift device 4 has a pair of guide rails 5A and 5B fixed to a hoistway wall, and is provided with a hoisting table 6 that moves up and down along the guide rails 5A and 5B using a driving device (not shown). The parked vehicle 3 mounted on the movable tray 7 is placed on the vehicle, and after moving to a predetermined parking floor, the parked vehicle 3 is moved to a predetermined space together with the movable tray 7 and stored. A pit 8 is formed in the lower part of the hoistway constituting the lift device 4.

  As shown in the plan view and the side view of FIGS. 2 and 3, the lifting platform 6 constituting the lift device 4 has a pair of end lateral members 9A and 9B facing each other, and the end lateral members 9A, 9B is firmly connected by connecting members 10A, 10B, and 10C. At one end of the end lateral members 9A and 9B, the upper guide members 11A and 11B that run in the vertical direction along the back side of the guide rails 5A and 5B and the front sides of the guide rails 5A and 5B are provided. Lower guide members 12A and 12B that run in the vertical direction and side guide members 13A and 13B that run in the vertical direction along the side surface of the guide rail 5 are rotatably supported.

  The tray feeding device shown in detail in FIG. 5 is formed at the position centering on the end lateral members 9A and 9B and the connecting members 10B and 10C on the lifting platform 6, and parked above the tray feeding device. A movable tray 7 on which a vehicle can be mounted is placed. The connecting members 10B and 10C or members coupled between them include guide rollers 14A and 14B for guiding the moving direction when the movable tray 7 carrying the parked vehicle is moved in the vertical direction, and the movable tray 7 in the horizontal direction. Guide rollers 15A and 15B that guide the direction of movement when moving are rotatably supported.

  FIG. 4 is a side view showing a state in which the lifting platform 6 is assembled to the guide rails 5A and 5B. The end lateral member 9A includes a lifting platform mounting portion 16 that is a portion on which the parked vehicle is actually mounted. It has a cantilever support portion 17 that cantilever-supports the lifting platform mounting portion 16 to the guide rail 5A. The lifting platform mounting portion 16 is made of I-shaped steel, which is a strength member, and is arranged so that the upper end surface 16A and the lower end surface 16B are positioned in the lifting direction, and cantilevered on the guide rail 5A side of the lifting platform mounting portion 16 The parts 17 are joined together. The upper guide member 11A disposed on the back side of the guide rail 5A is rotatably supported on the cantilever support portion 17, and the lower guide member 12A disposed below the upper guide member 11A on the front side of the guide rail 5A. A predetermined opposing distance is ensured in the vertical direction between the upper guide member 11A and the lower guide member 12A.

  Between the contact portions of the upper guide member 11A and the lower guide member 12A to the guide rail 5A, a facing distance necessary for receiving the load of the elevator mount 16 and the parked vehicle is secured in the vertical direction, and the elevator mount The upper end face 16A of the I-shaped steel constituting the upper part 16 is located below the contact portion of the upper guide member 11A with the guide rail 5A, and the lower end face 16B of the I-shaped steel constituting the lifting platform mounting part 16 is the lower guide. Mounted on a lifting platform so as to be located above the contact portion of the member 12A with the guide rail 5A and to be accommodated by using the above-described facing distance between the contact portions of the upper guide member 11A and the lower guide member 12A with the guide rail 5A. The thickness in the same direction of the portion 16 is set.

  The lifting platform mounting portion 16 is a strength member, and becomes a heavy load because a parked vehicle is mounted. Since the lifting platform mounting portion 16 has a cantilever support structure by the cantilever support portion 17, the upper guide member 11A and the lower guide member 12A.

  As can be seen from this description, the lifting platform mounting portion 16 does not have a conventional bracing material that protrudes greatly downward from the facing portion of the upper guide member 11A and the lower guide member 12A. In particular, the cantilever support portion 17 that cantilever-supports the lifting platform mounting portion 16 secures a facing distance between the upper guide member 11A and the lower guide member 12A, but both end surfaces 16A and 16B are utilized using this portion. Since the lifting platform mounting portion 16 made of I-shaped steel is disposed above and below in the lifting / lowering direction, the lifting / lowering platform 6 as a whole can have the thickness in the lifting / lowering direction within the facing distance.

  According to such a configuration, the upper guide members 11A and 11B and the lower guide members 12A and 12B are arranged at a predetermined distance so that the loads of the lifting platform mounting part 16 and the parked vehicle can be received by the cantilever support member 17. However, since this distance can be fully utilized to set the thickness of the lifting platform 16 or the lifting platform 6 in the lifting direction, it is possible to reduce the size without the conventional brace that protrudes greatly downward. It can be set as the lift apparatus for parking apparatus. For this reason, the depth of the pit 8 shown in FIG. 1 can also be suppressed.

  The side guide members 13A and 13B provided on the side surfaces of the guide rails 5A and 5B are used to assist the elevating platform 6 along the guide rails 5A and 5B, and a plurality of side guide members 13A and 13B may be provided for each guide rail. Although detailed description is omitted, the guide rail 5B side has the same configuration.

  In the vicinity of the guide rails 5A and 5B, a lift device motor 18 is vertically arranged at a position where it does not interfere when the lifting platform 6 moves up and down, and the rotation shaft of the lift device motor 18 is illustrated in detail. The rotary shaft 20 is connected to a rotary shaft 20, which will be described in detail later, through a conversion device 19 made of a transmission component such as a gear, and the rotary shaft 20 is rotated by the rotation of the lift device motor 18. A sprocket 21A is coupled to the rotary shaft 20, one end of the chain 22A hung on the sprocket 21A is connected to the end lateral member 9A by an end coupling portion 23, and the other end of the chain 22A is not shown. It is connected to the lift weight.

  Furthermore, the drive apparatus of the lift apparatus 4 is demonstrated using FIG. A beam member 24 is coupled between the opposed portions of the pair of guide rails 5A and 5B, and a pair of bearings 25A and 25B are supported on the beam member 24. The rotary shaft 20 is rotatably supported between the bearings 25A and 25B. A pair of sprockets 21A and 21B are coupled to the rotary shaft 20, and chains 22A and 22B are hung on the respective sprockets 21A and 21B. As described above, one end of each of the chains 22A and 22B is connected to the end lateral members 9A and 9B, and the other end is connected to a lift weight 26 disposed on the back side of the guide rails 5A and 5B. . The lift weight 26 is guided in the vertical direction by a pair of guide rails 27A and 27B provided upright on the back side of the guide rails 5A and 5B.

  When the rotating shaft 20 is rotated by the lift device motor 18, the sprockets 21A and 21B coupled to the rotating shaft 20 are also rotated, and the chains 22A and 22B hung on the sprockets 21A and 21B are moved to raise or lower the elevator platform 6. Lower. At this time, the lifting platform 6 is guided so as to move up and down smoothly by the upper guide members 11A and 11B and the lower guide members 12A and 12B arranged along the guide rails 5A and 5B, and the other ends of the chains 22A and 22B. Assisted by a lift weight 26 connected to.

  On the other hand, on the upper surface of the lifting / lowering base 6, a frame 28 having a structure allowing the guide rollers 14A and 14B and the guide rollers 15A and 15B shown in FIGS. A tray feeding device is configured on 28. Here, the guide rollers 14A and 14B and the guide rollers 15A and 15B are not shown. The tray feeding device includes a switching drive device configured on the support plate 29 in the center, a first drive device configured on the support plate 30, a second drive device configured on the support plate 31, and a switching drive device. And a connecting rod 32 for connecting the first driving device and a connecting rod 33 for connecting the switching driving device and the second driving device.

  The switching drive device configured on the central support plate 29 includes a motor 34, a rotating shaft 35 that is rotated by the motor 34, and a lever 36 that has a longitudinal intermediate portion connected to the rotating shaft 35. Is configured.

  The first drive device configured on the support plate 30 includes a rotation plate 38 rotatably provided on the support plate 30 by a rotation shaft 37, a motor 39 attached to the rotation plate 38, and a friction roller that is rotationally driven by the motor 39. And a plurality of guide rollers 41 arranged at equal intervals, for example, at the apexes of a virtual square centered on the rotation shaft 37. The same applies to the second drive device configured on the support plate 31. The rotary plate 43 is rotatably provided on the support plate 31 by the rotary shaft 42, the motor 44 is attached to the rotary plate 43, and is driven to rotate by the motor 44. A feed roller 45 that is a friction roller, and a plurality of guide rollers 46 that are arranged at equal intervals around the rotation shaft 42.

  One end of the rotatable lever 36 of the switching drive device formed on the support plate 29 is connected to the end of the rotary plate 38 of the first drive device via the connecting rod 32, and the other end of the lever 36 is connected. The end of the rotary plate 43 of the second drive device is connected to the end via a connecting rod 33. In the state shown in the drawing, the feed roller 40 of the first drive device and the feed roller 45 of the second drive device are oriented in the longitudinal direction of the lifting platform 6, but the lever 36 is moved counterclockwise by the motor 34 of the switching drive device. When driven to rotate 90 degrees, the first driving device connected via the connecting rod 32 rotates the rotating plate 38 counterclockwise by 90 degrees around the rotating shaft 37 and is connected via the connecting rod 33. The two-drive device rotates the rotating plate 43 by 90 degrees counterclockwise about the rotating shaft 42, and the feed rollers 40 and 45 face the width direction of the lifting platform 6. The positions of the motors 39 and 44 at this time are indicated by dotted lines.

  Now, when the movable tray 7 on which the parked vehicle is mounted is placed on the lift 6 of the lift device 4 shown in FIG. 1, the load of the parked vehicle is placed on the lift mounting portion 16 of the lift 6 as can be seen from FIG. However, this load pushes the upper guide members 11A and 11B to the back side of the guide rails 5A and 5B on the same virtual plane, and also presses the guide members 12A and 12B to the front side of the guide rails 5A and 5B. Thus, the lifting platform mounting portion 16 disposed on the virtual plane at substantially the same position receives a force in the thickness direction. For this reason, the lifting platform mounting part 16 can maintain sufficient mechanical strength without providing a brace material on the lower side of the lifting platform mounting part 16 as in the prior art. Accordingly, the lifting platform mounting portion 16 can be made of I-shaped steel easily because it can obtain strength without increasing the thickness in the vertical direction.

  When the lift tray motor 18 shown in FIG. 5 is driven in the upward direction with the movable tray 7 on which the parked vehicle is mounted on the elevator platform 6, the rotating shaft 20 rotates and is coupled to the rotating shaft 20. The sprockets 21A and 21B also rotate, and the chains 22A and 22B move. At this time, the lift weight 26 connected to one end of the chains 22A and 22B moves in the downward direction along the guide rails 27A and 27B, and the lifting platform 6 connected to the other end of the chains 22A and 22B is an upper guide member. 11A, 11B, the lower guide members 13A, 13B, and the side guide members 12A, 12B are moved in the upward direction along the guide rails 5A, 5B while being guided by the side guide members 12A, 12B.

  After that, when the parking floor of the parked vehicle is reached, if the parking space is in the horizontal direction of the lifting platform 6, the motor 34 of the switching drive device configured at the center of the tray feeder is driven, and the first drive device and the second drive device are driven. The feed rollers 40 and 45 of the driving device are switched sideways. Thereafter, when the motors 39 and 44 of the first drive device and the second drive device are driven, the feed rollers 40 and 45 are in pressure contact with a fixed guide (not shown) provided at the lower portion of the movable tray 7 and rotate in the lateral direction. Therefore, it is possible to move the movable tray 7 in the horizontal direction and lower it from the lifting platform 6. At this time, the guide rail guide rollers 15A and 15B shown in FIG. Thereafter, the movable tray 7 is moved to the parking space side while controlling the tray feeding device on the parking space side by a known method.

  In this way, the lifting platform 6 constituting the lift device 4 has an upper guide member 11A, 11B and a lower guide member 12A so as to sandwich the back side and the front side of the guide rails 5A, 5B, respectively, as shown in FIG. , 12B and the cantilever support portion 17 which is cantilevered and supported by the guide rails 5A and 5B, and the lift platform mounting portion 16 which is mechanically coupled to the cantilever support portion 17 and mounts the parked vehicle. Since the transverse members 9A and 9B are configured and the lifting platform mounting portion 16 is formed of I-shaped steel with both end surfaces positioned in the lifting direction, even if a rotational moment acts on the lifting platform mounting portion 16 on which the parked vehicle is mounted. In the guide rails 5A and 5B, through the cantilever support portions 17 in which the upper guide members 11A and 11B and the lower guide members 12A and 12B are arranged so as to sandwich the guide rails 5A and 5B. In addition, the load of the parked vehicle can be easily received by the lifting platform mounting portion 16 which is a strength member made of I-shaped steel or the like, and the thickness of the lifting platform mounting portion 16 and the lifting platform 6 in the lifting direction is reduced. Can do. That is, it is not necessary to provide a brace material at the lower part of the lifting platform 6 shown in FIG. 1, and the depth of the pits 8 can be reduced accordingly.
