Description

  The present invention relates to a method for remodeling a vertical circulation parking apparatus for parking a vehicle and the vertical circulation parking apparatus.

  2. Description of the Related Art Conventionally, a vertical circulation parking device called a so-called tower parking is known as one form of parking facility.

  As shown in FIGS. 8 to 11, the existing vertical circulation parking apparatus has a pair of upper sprockets 2 rotatably disposed on an upper frame 1 installed on an upper part of a building (not shown). A pair of lower sprockets 4 is rotatably disposed on the lower frame 3 installed at the lower part of the chain. Between the upper sprocket 2 and the lower sprocket 4, a chain 6 composed of a plurality of links 5 is looped endlessly. Has been.

  As shown in FIG. 9, the chain 6 is provided with an attachment 7 for each of the four links 5, and a cage 8 is pivotally attached to each attachment 7. Further, as shown in FIG. 8, a motor 2a as a driving means is connected to the upper sprocket 2. The motor 2a circulates the chain 6 via the upper sprocket 2 and circulates the cage 8 in the vertical direction. Yes. In FIG. 8, only two cages 8 positioned at the upper and lower ends are shown, and the other cages 8 are omitted.

The cage 8 includes a cage suspension shaft 9 that is attached to the attachment 7 and extends in the horizontal direction. A cage frame 10 is pivotally supported at both ends of the cage suspension shaft 9. 11 is stretched over. The cage frame 10 of the cage 8 connects the upper side portion 12 attached to the cage suspension shaft 9, the column portion 13 disposed downward from both ends of the upper side portion 12, and the lower ends of the column portions 13 on both sides. And a lower side portion 14 that supports the pallet 11. Further, as shown in FIG. 10, the column portion 13 of the cage frame 10 is 4.5 inward in the axial direction (pallet longitudinal direction) of the cage suspension shaft 9 from the vertical line toward the lower side on both sides of the cage suspension shaft 9. It has an angle θ ₀ inclined at an angle of not less than 6 ° and not more than 6 °, and the distance between the lower sides 14 in the axial direction of the cage suspension shaft 9 is larger than the distance between the upper sides 12 in the axial direction of the cage suspension shaft 9. It is narrow. Therefore, the lower side portion 14 of the cage frame 10 disposed in the upper cage 8 is positioned on the inner side in the axial direction of the cage suspension shaft 9 relative to the upper side portion 12 of the cage frame 10 disposed in the cage 8 directly below, The cage 8 that is suspended by the other cage 8 and the other cage 8 that is suspended immediately below are prevented from interfering with each other. Further, when the longest vehicle 15 that can be loaded on the pallet 11 is received, the front and rear ends of the vehicle 15 protrude outward from the cage frame 10 as shown in FIG.

  In such a vertical circulation parking device, when the vehicle 15 is parked, the chain 6 is circulated and the empty cage 8 is stopped at the entrance (not shown) of the building located below the lower sprocket 4. Then, the vehicle 15 is moved forward into the empty cage 8 and loaded on the pallet 11, and the vehicle 15 is moved to the upper inside of the building by the circulation of the chain 6. Further, when the vehicle 15 is unloaded, the chain 8 is circulated, the cage 8 loaded with the vehicle is stopped at the doorway, and the vehicle is moved forward.

  On the other hand, a vertical circulation parking device that requires the vehicle 15 to move backward, such as a rear advancement warehouse, is difficult to use for those who are not good at driving, so when constructing a new vertical circulation parking device, It has been considered to arrange a turning means for turning the vehicle so that the vehicle can advance and advance in advance.

  Here, when showing an example of a configuration provided with a turning means in the vertical circulation parking device, an example of the turning means is a jack-up device for separating the pallet upward from the cage frame on the floor of the building located at the entrance and exit, And a pallet turning device that turns the pallet. When the vehicle enters the pallet from the entrance, the pallet is raised to a predetermined height by the jack-up device so that the vehicle and the pallet do not interfere with the cage frame pillar. In addition, the vehicle and the pallet are turned 180 ° by the pallet turning device, the pallet is lowered by the jack-up device, the pallet is returned to the original height, and the vehicle is moved forward from the doorway (for example, patent) Reference 1).

In addition, as another example of the structure of the turning means, the other example of the turning means includes a turntable having a lifting and lowering function and a turning function on the floor of the building located at the entrance and exit, and cages located on both sides of the turntable. When the vehicle enters the pallet from the doorway, the lower part of the cage frame is gripped by the cage frame opening and closing device, the pallet is lifted by the turntable and the lower part of the cage frame is moved outward. To prevent the vehicle and pallet from interfering with the column of the cage frame. Further, the vehicle and pallet are turned 180 ° by the turntable, the pallet is lowered by the turntable and the lower part of the cage frame is returned to the original position. The vehicle is moved forward from the doorway (see, for example, Patent Document 2).
Japanese Unexamined Patent Publication No. 55-23207 JP-A-61-75172

  However, when the existing vertical circulation parking apparatus shown in FIGS. 8 to 11 is modified to include turning means, the column portion 13 of the cage frame 10 extends from the vertical line to the pallet length from the vertical line. Since the vehicle 15 is tilted inward by 4.5 ° or more and 6 ° or less, the front and rear ends of the vehicle 15 interfere with the column part 13 of the cage frame 10 when turning the vehicle 15, and the total length of the vehicle 15 to be stored is the existing vertical There was a problem that it was more limited than in the case of a circulating parking device. In addition, since the existing vertical circulation parking device does not have a spatial margin that allows the cage to be enlarged in the vertical direction in the building, the vehicle turning as in Patent Document 1 does not interfere with the pillar portion of the cage frame. There is a problem that a space for raising the vehicle and the pallet to a predetermined height cannot be provided in the cage, and the vehicle cannot be applied to an existing vertical circulation parking apparatus. Further, when the cage frame opening / closing device is installed and the lower side portion of the cage frame is moved outward as in Patent Document 2, when the lower side portion is moved, the lower side portion of the cage frame is an existing vertical circulation type. There was a problem that the cage frame opening and closing device could not be applied, as in Patent Document 1, because it interfered with the building wall and frame of the parking device.

  In view of such circumstances, the present invention is able to reduce the vehicle's front entrance and front advancement without restricting the overall length of the vehicle to be stored, as compared with the existing vertical circulation parking device, even in the existing vertical circulation parking device. It is an object of the present invention to provide a method for remodeling a vertical circulation parking apparatus and a vertical circulation parking apparatus that can be used.

The present invention suspends a chain endlessly between an upper sprocket and a lower sprocket, and hangs a plurality of cages each provided with an in-vehicle pallet at a predetermined interval in the extending direction of the chain. A method of remodeling a vertical circulation parking device with cage frames located on both sides in the longitudinal direction of the pallet,
In order to prevent the lower end of the cage located in the upper part and the upper end of the other cage located in the immediate lower part of the cage from interfering with each other, the gap between the cages is arranged wider than that before the remodeling with respect to the chain,
Vertically, the pillars on both sides of the cage frame in the pallet width direction are vertically inclined from the upper side to the lower side from an angle inclined 2 ° inward from the vertical line toward the pallet longitudinal direction from the upper side to the lower side with respect to the vehicle longitudinal direction. It is arranged between the line and the angle inclined by 1 ° outward in the pallet longitudinal direction,
Below the lower sprocket, a turning means for allowing the vehicle to turn together with the pallet is disposed so as to be able to move up and down.
The present invention relates to a method for remodeling a vertical circulation parking apparatus, wherein the vehicle is remodeled so as to be able to enter a front approach store and a previous advance store.

  In the remodeling method of the vertical circulation parking apparatus of the present invention, it is preferable that the intervals between attachments that are provided at every plurality of links of the chain and pivotally attach the cage are wider than before remodeling.

  In the remodeling method of the vertical circulation parking apparatus of the present invention, it is preferable to increase the number of links between attachments after remodeling than before remodeling.

The present invention suspends a chain endlessly between an upper sprocket and a lower sprocket, and hangs a plurality of cages each provided with an in-vehicle pallet at a predetermined interval in the extending direction of the chain. A vertical circulation parking device with cage frames located on both sides in the longitudinal direction of the pallet,
Arrange the cage in the chain so that the lower end of the cage located at the top and the upper end of the other cage located directly below the cage do not interfere with each other,
Vertically, the pillars on both sides of the cage frame in the pallet width direction are vertically inclined from the upper side to the lower side from an angle inclined 2 ° inward from the vertical line toward the pallet longitudinal direction from the upper side to the lower side with respect to the vehicle longitudinal direction. Arranged between the line and the angle inclined 1 ° outward in the pallet longitudinal direction,
Below the lower sprocket, a turning means for turning the vehicle together with the pallet is arranged so as to be able to move up and down.
According to the present invention, there is provided a vertical circulation parking apparatus configured such that the vehicle can advance in front and advance.

  As described above, the cage is arranged with a wider interval between the cages, so that the lower end of the cage located at the upper portion and the upper ends of other cages located immediately below the cage do not interfere with each other, From the angle at which the pillar portion of the cage frame is inclined 2 ° from the vertical line to the inside of the pallet longitudinal direction from the upper side to the lower side, to the angle at which the column frame is inclined 1 ° from the vertical line to the outer side in the pallet longitudinal direction. Since the vehicle is further provided with a turning means, the vehicle can be turned with respect to the pillar portion of the cage frame without restricting the total length of the vehicle to be stored from the existing vertical circulation parking device, so And the advance warehouse can be performed. Moreover, even if it is an existing vertical circulation parking device, the vehicle can be moved forward and forward by improvement, and can be easily used by a user who is not good at moving backward.

  Also, if the distance between the attachments that are installed at multiple links in the chain and the cage is pivoted is wider than before the remodeling, the lower end of the column is positioned directly below when the angle of the column of the cage frame is set. It can be easily arranged so that it does not come into contact with other cages, so that the cage can be circulated and at the same time the vehicle can turn with respect to the pillars without restricting the total length of the entering vehicle from the existing vertical circulation parking device In addition, it is possible to appropriately perform the front entry warehouse and the advance entry warehouse of the vehicle.

  Furthermore, if the number of links between attachments is increased after remodeling than before remodeling, the lower end of the pillars will not come into contact with other cages located directly below when the angle of the pillars of the cage frame is set. Since the cage can be circulated more easily, the vehicle can be turned with respect to the pillar portion without restricting the total length of the vehicle to be stored at the same time as the existing vertical circulation parking device, Pre-advance warehouse can be suitably performed.

  According to the modification method of the vertical circulation parking device and the vertical circulation parking device of the present invention, even in the existing vertical circulation parking device, the distance between the cages is increased with respect to the extending direction of the chain. At the same time, the column part of the cage frame is inclined by 1 ° from the vertical line toward the pallet longitudinal direction from the vertical line toward the pallet longitudinal direction from the vertical line to the pallet longitudinal direction inside from the vertical line. By arranging the turning means and further providing turning means, the vehicle can be turned and the front entry warehouse and the advance entry warehouse of the vehicle can be turned without restricting the total length of the vehicle to be received from the existing vertical circulation parking device. An excellent effect that it can be performed can be achieved.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 7 show embodiments of the present invention. In the figure, the same reference numerals as those in FIGS. 8 to 11 denote the same components, and the basic configuration is shown in FIGS. 11 is the same as the conventional one shown in FIG.

  In the embodiment for carrying out the present invention, the chain 6 and the cage 8 are changed in the existing vertical circulation parking device, and a turning means is newly provided.

  The chain 17 in the embodiment of the present invention is formed with the link 5 having substantially the same length and the same number as the chain 6 installed in the existing vertical circulation parking device when the chain itself is replaced. Attachments 7 are provided for every five or six links (five in FIG. 1), and the distance between the attachments 7 is wider than that of the chain 6 of the existing vertical circulation parking device. . Each attachment 7 has a cage 18 pivotally attached thereto, and the lower end of the cage 18 positioned above and the upper end of the other cage 18 positioned directly below increase the number of links between the attachments 7. Therefore, there is a distance L in the vertical direction so as not to interfere with each other. Here, the chain 17 may replace only the link 5 provided with the attachment 7.

  The cage 18 is attached to the attachment 7 and extends in the vehicle front-rear direction, the cage suspension shaft 19 extending in the vehicle front-rear direction, the cage frame 20 pivotally supported at both ends in the vehicle front-rear direction, and the cage frames 20 on both sides. The lower frame frame 21 is disposed on the lower frame frame 21, and an in-vehicle pallet 22 is placed on the lower frame frame 21.

The cage frame 20 of the cage 18 is attached to the cage suspension shaft 19 and extends in the pallet width direction (vehicle width direction) and a column disposed downward from both sides of the upper side 23 in the pallet width direction. And a lower side portion 25 extending in the pallet width direction so as to connect the lower ends of the column portions 24 on both sides. Here, the pivot position of the upper end of the column portion 24 with respect to the cage suspension shaft 19 of the cage frame 20 is substantially the same as the pivot position of the upper end of the column portion 13 with respect to the cage suspension shaft 9 of the existing vertical circulation parking apparatus shown in FIG. As shown in FIG. 2, the column portion 24 is downward from the pivoting position (upper) from the pivoting position (upper) to the lower side from an angle inclined 2 ° inward in the longitudinal direction of the pallet from the vertical line. It is arrange | positioned to the angle which inclines 1 degree to the pallet longitudinal direction outer side from a perpendicular line (it shows by angle (theta) ₁ in FIG. 2). Moreover, the pillar part 24 is comprised by the substantially same height as the pillar part 13 of the cage frame 10 arrange | positioned at the cage 8 of the existing vertical circulation parking apparatus. Therefore, in this illustrated example, the interval between the lower end of the column part 24 and the lower side part 25 located on both sides in the longitudinal direction of the pallet is formed larger than that of the existing vertical circulation parking device shown in FIG. When the vehicle 15 that can be loaded on the vehicle 22 is received, the front and rear ends of the vehicle 15 do not protrude outward from the cage frame 20.

  The lower frame frame 21 of the cage 18 includes an edge frame 26 that forms a plane having a predetermined width from the lower side 25 of the cage frame 20 on both sides inward in the pallet longitudinal direction, and the pallet width direction of the edge frames 26 on both sides. A side frame 27 extending in the longitudinal direction of the pallet from both sides is provided, and guide brackets 28 projecting upward to form slopes at connection positions (four locations) between the edge frame 26 and the side frame 27. Is provided.

  The in-vehicle pallet 22 includes a flat surface 22a having a size that does not protrude outward from the cage 18 in the vehicle front-rear direction and the vehicle width direction, and the side surface 22b extending in the longitudinal direction of the pallet 22 has an outer side in the vehicle width direction. A guide member 29 protruding to the left is provided. When the pallet 22 is placed on the lower frame frame 21, the guide member 29 slides on the slope of the guide bracket 28 to guide the pallet 22 to a predetermined position.

  On the other hand, the floor of the building is provided with a turning means for turning the pallet 22 so as to be positioned below the lower sprocket 4 (see FIG. 8). The turning means is not particularly limited as long as it can turn the vehicle 15 placed in the existing building and loaded on the pallet 22 together with the pallet 22, but as an example, as shown in FIGS. The swivel means 30 has a base frame 32 that can run on a bottom surface 31 that is formed by digging a floor of a building, and an elevating frame 34 is arranged on the base frame 32 via a plurality of ball screws 33 standing upright. The elevating frame 34 is rotatably arranged on the lower surface and is driven by a sprocket 35 fitted on the ball screw 33, and is rotatably arranged on the upper surface and is screwed to the ball screw 33 and integrally with the driven sprocket 35. When the motor 38 is driven, a rotating nut portion 36 and a motor 38 that circulates a chain 37 wound endlessly on the driven sprocket 35 are provided. Causes the orbiting chain 37 to rotate the driven sprocket 35 and the nut portion 36, lifting frame 34 is raised and lowered relative to the ball screw 33. In addition, the elevating frame 34 is provided with a pedestal portion 40 arranged via a leg portion 39, and the pedestal portion 40 is positioned below the pallet 22 and is rotatably arranged; A revolving gear 42 located on the lower surface of the support frame 41 and arranged concentrically with the center of rotation of the support frame 41; a drive gear 43 that meshes with the revolving gear 42; and a revolving motor 44 that rotates the drive gear 43. When the turning motor 44 is driven, the turning gear 42 is rotated via the drive gear 43 so that the support frame 41 turns with respect to the pedestal portion 40.

  The operation of the embodiment of the present invention will be described below.

  When parking the vehicle 15, as in the existing vertical circulation parking device, the chain 17 circulates and the empty cage 18 is stopped at the entrance (not shown) of the building located below the lower sprocket 4. Then, the vehicle 15 is moved forward into the empty cage 18 and loaded on the pallet 22, and the vehicle 15 is moved to the upper inside of the building by the circulation of the chain 17.

  When the vehicle 15 is to be unloaded, the chain 17 is circulated, the cage 18 loaded with the unloaded vehicle 15 is stopped at the entrance of the building, and the vehicle 15 is turned 180 ° together with the pallet 22 by the turning means 30. The vehicle 15 is moved forward from the doorway. At this time, the turning means 30 raises the elevating frame 34 by the motor 38 and the like to support the pallet 22 by the support frame 41 when the vehicle 15 leaves, and the pallet 22 is slightly lifted from the lower frame frame 21 of the cage 18. And the guide member 29 and the guide bracket 28 are disengaged from each other, the vehicle 15 is turned 180 ° together with the pallet 22 by the drive gear 43 and the turning gear 42, and the elevating frame 34 is lowered to lower the pallet 22. The vehicle 15 is placed on the lower frame frame 21 and the pallet 22 is returned to its original height so that the vehicle 15 is moved forward from the doorway.

Further, when the vehicle 15 turns together with the pallet 22, the vehicle 15 does not interfere with the column part 24 as shown in FIG. By arranging 24 within the range of the angle θ ₁ with respect to the vertical line, it is not suppressed more than the existing vertical circulation parking device.

  Here, when the angle range in which the column part 24 can be tilted is shown by a test result of a specific arrangement, the angle of the column part 24 of the cage frame 20 is changed from the upper side to the lower side as shown in the graph of FIG. When the angle is inclined 2 ° inward in the pallet longitudinal direction from the vertical line (88 ° in FIG. 7), the minimum clearance between the pillar 24 and the vehicle 15 is about 30 mm, and the vehicle 15 It is clear that the vehicle 15 is turned without interfering with the part 24. Further, when the angle of the column portion 24 of the cage frame 20 is set to an angle (91 ° in FIG. 7) that is inclined 1 ° outward from the vertical line in the pallet longitudinal direction from the upper side to the lower side, A gap between a component member (not shown) such as another device and the pillar portion 24 is about 30 mm, which is the minimum gap in which the cage 18 can circulate, and the cage portion 18 can circulate without interfering with the component member. it is obvious. Furthermore, when the angle of the column part 24 is made larger than the angle inclined 2 ° inward from the vertical line in the pallet longitudinal direction from the upper side to the lower side, the vehicle 15 and the column part 24 interfere to turn the vehicle 15 If the angle of the pillar portion 24 is larger than the angle inclined 1 ° from the vertical line to the longitudinal direction of the pallet from the upper side to the lower side, the structural member of the building frame or other device There is a problem that the column portion 24 interferes with the circulation of the cage 18. Furthermore, when the angle of the column part 24 of the cage frame 20 is the same angle as the vertical line from the upper side to the lower side (90 ° in FIG. 7), the clearance between the column part 24 and the vehicle 15 when turning is set. Is about 95 mm, and the vehicle 15 can be turned optimally, and the gap between the component member and the column portion 24 is about 45 mm, so that the cage 18 can be circulated optimally. In addition, the vehicle total length at the time of calculating | requiring the tiltable range of the pillar part 24 shown in FIG. 7 is based on the largest vehicle full length which can be parked with the existing vertical circulation parking apparatus.

  In this way, since the gap between the cages 18 is widened with respect to the chain 17, the lower end of the cage 18 positioned at the upper portion and the upper ends of the other cages 18 positioned immediately below the cage 18 do not interfere with each other. In addition, the column portion 24 of the cage frame 20 is inclined outwardly from the vertical line by 2 ° toward the inside of the pallet longitudinal direction from the upper side to the lower side. Since the vehicle is further provided with a turning means 30 with an inclination angle of 1 °, the entire length of the vehicle 15 to be stored is limited to the column portion 24 of the cage frame 20 without restricting the total length of the existing vertical circulation parking device. Thus, the vehicle 15 can be turned and the vehicle 15 can be moved forward and forward. Moreover, even if it is an existing vertical circulation parking device, the vehicle 15 can be moved forward and forward by improvement so that it can be easily used by a user who is not good at moving backward.

  Further, in the embodiment of the present invention, when the intervals between the attachments 7 that are provided at every plurality of links of the chain 17 and are pivotally attached to the cage 18 are arranged wider than before the modification, the angle of the column portion 24 of the cage frame 20 is changed. When it is set, the lower end of the pillar portion 24 can be easily arranged so as not to come into contact with the other cage 18 located immediately below. Therefore, the cage 18 is circulated and at the same time, the entire length of the vehicle 15 to be stored is circulated in the existing vertical circulation. Without limiting from the parking system, the vehicle 15 can turn with respect to the pillar portion 24, and the vehicle 15 can be appropriately moved in and out of the vehicle.

  Furthermore, in the embodiment of the present invention, if the number of links between the attachments 7 is increased after remodeling than before remodeling, the lower end of the column 24 is set when the angle of the column 24 of the cage frame 20 is set. However, since it can be arranged more easily so as not to come into contact with other cages 18 located immediately below, it is possible to circulate the cage 18 and at the same time, without restricting the total length of the vehicle 15 to be received from the existing vertical circulation parking device, The vehicle 15 can turn with respect to the column part 24, and the front approach storage and the front advance storage of the vehicle 15 can be performed suitably.

  In addition, the remodeling method of the vertical circulation type parking apparatus of the present invention and the vertical circulation type parking apparatus are not limited to the above-described illustrated examples, and various modifications can be made without departing from the gist of the present invention.
