A plurality of beams 103 are installed, and a self-supporting steel structure 105 (parking tower) is configured by installing diagonal members 104 between adjacent beams 103 above and below the installed beams 103. A ceiling beam 106 is provided on the upper portion of the steel structure 105, and a roof 107 is provided on the upper surface thereof. An exterior material 108 is provided on the outer peripheral surface of the main pillar 102. A vertical circulation parking device main body 110 is incorporated in the box-shaped space 109 of the steel structure 105. The entry part 111 (entrance / exit) of the parking apparatus main body 110 is generally provided in the lower part of the parking apparatus 101, and the height distance H0 is from the entry floor 138 where the entry part 111 is provided to the ceiling beam 106. It has become.

  The parking device main body 110 has endless main chains 114 wound between upper and lower sprockets 112, 113 each in a pair of front and rear, and a number of suspension materials are spaced around the two main chains 114 at appropriate intervals. 115 (attachment) is attached. A vehicle mounting cage 116 is suspended from the front and rear ends of the corresponding suspension members 115 on the front and rear sides of the suspension members 115.

  The parking device main body 110 is provided with a drive mechanism 117 for rotating the upper sprocket 112 at the top. The drive mechanism 117 uses a beam corresponding to the front and rear above the steel structure 105 as an upper receiving beam 118, and a gear is mounted on a frame 120 on a base 119 (machine base) installed between the receiving beams 118. A transmission mechanism 142 is installed. The gear transmission mechanism 142 is driven by a motor provided at the center of the base 119. The lower sprocket 113 is supported by a support mechanism 123 provided on the lower receiving beam 118.

  The beam 103 is provided with a straight outer guide rail 121 that guides the lower roller 124 of the vehicle mounting cage 116 when moving up and down, and the straight guide rail 121 is provided between the base 119 and the support mechanism 123. 122 is provided in the vertical direction.

  8 is an overall perspective view of the vehicle mounting cage shown in FIG. As a general structure of the above-mentioned vehicle mounting cage 116 (hereinafter also simply referred to as “cage”), a chassis 126 (pallet) that is elongated in the vehicle front-rear direction and has two concave left and right concave vehicle road surfaces 125 (wheel entry paths). The left and right lower parts are fixed to the front and rear end sides of the chassis 126, and the front and rear of the gate shape (reverse U-shaped) are inclined so as to spread apart in the front-rear direction toward the top. Rear cage frames 127 and 128, a connecting shaft 130 for connecting the upper central portions of the front and rear cage frames 127 and 128, and a suspension projecting forward and rear outward from the front and rear cage frames 127 and 128 And a shaft 129. The suspension shaft 129 is suspended between the front ends of the suspension material 115. A shoulder roller 132 is provided on the upper portion of the rear cage frame 128. The shoulder roller 132 is engaged with a lower reverse arc guide 131 that guides the cage 116 to be reversed by the lower reverse portion 135. An upper reversing arc guide 134 with which the shoulder roller 132 is engaged is provided in the upper reversing portion 133 described later.

  In this type of vertical circulation parking apparatus, the cage 116 is limited in the box-like space 109 (FIGS. 6 and 7) of the steel structure 105 (parking tower) in order to increase the accommodation efficiency. In order to accommodate as many cages 116 as possible within the height and length and breadth range, the cages 116 are arranged in the up and down direction and the left and right direction (direction perpendicular to the vehicle entry direction).

  9 is an enlarged front view of the upper reversing unit (drive unit) of the vertical circulation parking apparatus shown in FIG. 6, and FIG. 10 is an enlarged front view of the lower reversing unit (insertion unit) of the vertical circulation parking apparatus. It is. With reference to these drawings, the positional relationship of each component in the vertical circulation parking apparatus 101 will be described.

  As shown in FIG. 9, the upper sprocket 112 has a distance H30 from the upper surface of the receiving beam 118 provided in the steel structure 105 to the axis C1. The upper sprocket 112 has a diameter D0, and the distance L is from the axis C1 to the suspension position 136 of the suspension material 115 provided on the main chain 114 driven by the upper sprocket 112. The suspension member 115 is formed to have an attachment link length A0 to the main chain 114 and an arm length B0 protruding from the main chain 114. Further, in this state, the distance S0 is from the upper end of the suspension member 115 to the lower surface of the ceiling beam 106 of the steel structure 105. The distance from the upper surface of the receiving beam 118 to the lower surface of the ceiling beam 106 is a distance H20.

  Also, as shown in FIG. 10, the lower sprocket 113 is also formed with a diameter D0, and the shaft core C2 of the lower sprocket 113 is supported at a height H10 by a support mechanism 123 provided on the lower receiving beam 118. ing. The distance L is from the lower sprocket 113 to the suspension position 136 of the suspension material 115 provided on the main chain 114, and from the suspension position 136 of the suspension material 115 to the road surface 125 of the vehicle mounting cage 116. The distance is H40. The road surface 125 is at the same level as the ground floor 138. Further, the left / right cage 116 that moves up and down the left / right vertical movement path 139 formed between the straight guide rail 122 and the straight guide rail 121 moves in a state where the distance E is maintained. ing.

  Such a vertical circulation parking apparatus 101 has upper / lower reversing parts 133 and 135 (FIG. 9) as shown in the explanatory view showing the corner cutting lap state of the vehicle mounting cage during the lower reversing movement shown in FIG. , 10), when the cage 116 (cage group) circulates, the side of the chassis 126 of the upper cage 116 is inclined so as to spread apart from the lower cage 116 adjacent thereto. Intrusion into the triangular prism-shaped wrap space 140 at the upper left / right outer corner between 127 and 128 is allowed to be reversed. In this figure, the relative movement trajectory of the upper cage 116 is shown in a state where the lower cage 116 that reversely moves is fixed.

  However, if a part of the vehicle mounted in the triangular prism-shaped lap space 140 of the lower cage 116 protrudes, the chassis 126 of the upper cage 116 contacts the protruding portion of the vehicle mounted with the lower cage 116 at the time of the inversion. Will damage the vehicle. Therefore, in order to prevent the vehicle from entering the triangular prism-shaped lap space 140 when entering the vehicle, as shown in FIG. 10, the intrusion restricting member 141 (bar material) is located at the upper left and right positions of the front cage frame 127 (entrance side). , A plate material, a triangular plate material, etc.) is set, and a corner cutting region R0 where the vehicle M0 cannot enter is set. This corner cutting region R0 is set to be larger than the triangular prism-shaped wrap space 140 so that even if the chassis 126 of the upper cage 116 enters the triangular prism-shaped wrap space 140 during reversal, it does not contact the mounted vehicle at all. . Therefore, the specifications (vehicle height, vehicle width) of the vehicle M0 that can be accommodated are determined by the size of the corner cutting region R0. In this figure, the hatched portion shown in the upper corner of the vehicle mounting cage 116 is a corner cutting region R0, and the portion indicated by a two-dot chain line indicated by a width W and a height H50 is a vehicle accommodation region RV0.

  In addition, as a general vertical circulation type parking apparatus that circulates a vehicle-mounted cage in a vertical direction with a main chain wound on upper and lower sprockets, for example, there are inventions described in Patent Document 1 and Patent Document 2.

In addition, as another conventional technique, one that attempts to reduce the installation area of the entire parking device (see, for example, Patent Document 3), the drive device is divided into a lower unit, an intermediate unit, and an upper unit, and an electric motor is provided. There are some which attempt to prevent the drive unit from interfering with the cage by disposing the lower unit in a lower position (for example, see Patent Document 4).
Japanese Utility Model Publication 3-44917 Japanese Patent Laid-Open No. 9-209592 JP-A-9-184318 JP 11-324376 A

  By the way, in recent years, with various types of automobiles, automobiles with various specifications (vehicle width, vehicle height, vehicle length) have become widespread. In particular, in the case of a light vehicle, a conventional vehicle having a narrow vehicle width and a low vehicle height has been generally used. The number of one-box types is increasing, and even in ordinary cars, there is an increase in medium-box height (also called mid-roof) and high-box height (also called high-roof) one-box types (this specification and claims). In the scope documents, these medium and high cars are collectively referred to as “medium / high cars”).

  However, until a few decades ago, there were many low-height sedan-type regular vehicles, and the vertical circulation parking device installed at this time (hereinafter referred to as “the existing vertical circulation parking device”) Are generally installed exclusively for sedan-type ordinary vehicles (that is, only for low and high vehicles). This existing vertical circulation parking apparatus is the vertical circulation parking apparatus 101 as shown in FIGS. 6 to 11 described above, and as described above, the cages 116 are arranged in the vertical and horizontal directions. Therefore, the corner cutting region R0 of the upper corner of the cage 116 is large. Therefore, in the existing vertical circulation parking device 101, even when trying to accommodate the above medium and high vehicles, a part of the vehicle comes into contact with the corner cutting region R0, so that it is physically impossible to store the vehicle. Yes. For this reason, the existing vertical circulation parking apparatus 101 cannot respond to the widespread demand for storage of medium and high vehicles, resulting in a “deterioration of parking efficiency” in which the proportion of empty cages increases.

  On the other hand, in the existing vertical circulation parking system, the steel structure itself is sufficiently durable even after 10 years. There is a case where a remodeling (hereinafter also referred to as “device main body replacement remodeling”) in which only the parking device main body is completely replaced is left without being performed. However, when remodeling the main body of the device, simply incorporating a parking device main body that is almost the same as the existing one will cause the above "deterioration of parking efficiency" even after the remodeling. The significance of is lost. Therefore, a solution that can improve the deterioration of parking efficiency is eagerly desired. In addition, such a subject and its solution means are not described in the said patent documents 1-4.

  Therefore, an object of the present invention is to provide a remodeling method capable of improving the parking efficiency by remodeling the apparatus main body so as to accommodate medium and high cars.

  In order to achieve the above object, the present invention attaches a plurality of suspension materials at appropriate intervals to front and rear main chains wound between upper and lower sprockets provided at the front and rear, respectively, A remodeling method for replacing a parking device body in an existing vertical circulation parking device in which a vehicle mounting cage is suspended and circulated between materials in a steel structure or building enclosure. Reduce the number of meshing teeth of the upper and lower sprockets with which the main chain engages to a predetermined number to make the upper and lower sprockets smaller in diameter, and move the upper sprocket shaft core upward to a position suitable for winding the main chain. The distance from the axial center position of the upper and lower sprockets to the suspension position of the vehicle mounting cage by the suspension material is substantially the same as the suspension position of the vehicle mounting cage by the existing suspension material. To reduce the corner cutting region during circulation in the upper and lower reversing part of said vehicle mounting cage Te. As a result, by replacing and remodeling the parking device main body in the existing vertical circulation parking device, the space between the circulating cages is wider than before in the reversing part, and the chassis side part of the reversing cage is the upper left and right outer side of the adjacent cage Since the amount entering the corner is smaller than that of the existing parking device main body, the corner-cutting area of the vehicle-mounted cage can be reduced to increase the vehicle-accommodable area, and the existing vertical circulation parking The device can be modified to a vertical circulation parking device that can accommodate medium and high vehicles.

  In addition, the distance from the axial center positions of the upper and lower sprockets by the suspension material to the suspension position of the vehicle mounting cage is increased by extending the arm length of the suspension material to mount the vehicle on the existing suspension material. It is also possible to make the distance substantially the same as the suspension position of the cage and use the same number of suspension members as the existing vertical circulation parking device. Thereby, it is possible to modify the vehicle so as to accommodate medium and high vehicles with the same number of vehicle mounting cages as the existing vertical circulation parking device.

  Further, modification may be made in which the ceiling portion of the steel structure or building frame is moved upward in accordance with the distance by which the axial center position of the upper sprocket is moved upward. As a result, even if the position of the upper sprocket moves upward and approaches the ceiling beam of the steel structure or the building frame, it can be modified to a vertical circulation parking device that can accommodate medium and high vehicles with a simple modification. Can do.

  Further, if the number of meshing teeth to be reduced by the upper and lower sprockets is set to 1 to 3, the distance to move the axial center position of the upper sprocket upward is suppressed, and the existing steel structure or building frame is not modified. The corner-cutting area can be made smaller and can be modified to a vertical circulation parking device that can accommodate medium and high vehicles.

  The present invention modifies the existing vertical circulation parking device dedicated to low and high vehicles to a vertical circulation parking device that can accommodate medium and high vehicles by replacing and remodeling the parking device main body by means as described above. It becomes possible to do.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an enlarged front view of an upper part (drive unit) of a vertical circulation parking apparatus to which a modification method according to the present invention is applied, and FIG. 2 is a lower part (entrance part) of the vertical circulation parking apparatus shown in FIG. FIG. 3 is an explanatory view showing a corner cutting lap state of the vehicle mounting cage at the time of the reverse movement shown in FIG. Based on these drawings, a modification in which the parking apparatus main body 110 is replaced while leaving the steel structure 105 in the existing vertical circulation parking apparatus 101 shown in FIGS. In these drawings, a third modified example shown in FIG. 4D described later will be described as an example. Moreover, in the following description, the same code | symbol is attached | subjected and demonstrated to the structure same as the structure in the vertical circulation parking apparatus 101 mentioned above.

  First, main <non-modification items> and <modification items> in replacement modification of the parking apparatus main body 1 are listed.

<Non-modified items>
1. Overall height in steel structure 105 (height distance (H0) from entrance floor 138 to ceiling beam 106)
2. 2. Distance between main column 102 and beam 103 (FIG. 6) Height from the lower receiving beam 118 to the axis of the lower sprocket 33 (H10)
4). Height distance (H20) from the upper surface of the receiving beam 118 of the drive mechanism 117 to the lower surface of the ceiling beam 106
5. Mounting link length of suspension material 35 (A0)
6). Attachment link pitch of suspension 35 (every 4 links)
7). 7. Overall length of main chain 114 Distance (L) from the axis C1, C2 of the upper and lower sprockets 32, 33 to the suspension position 136 of the suspension member 35 (axis of the suspension shaft 129)
9. Overall dimensions of vehicle mounted cage 116 (external distance (W) of left and right vehicle surface 125 of chassis 126 (maximum vehicle width is determined))
10. Height distance (H40) from the suspension position 136 of the suspension member 35 to the road surface 125 of the chassis 126 of the cage 116
11. Distance between left and right cages 116 arranged on the left / right vertical movement path 139 (E)
These are the main <non-modified items>.

<Modification items>
I. The number of “meshing teeth” of the upper and lower sprockets 32, 33 is appropriately reduced (1 to 3). Even if the number of meshing teeth is reduced in this way, the attachment link length (A0) of the suspension member 35 is not changed, so that the upper and lower sprockets 32 and 33 become smaller in diameter (D3).
II. In order to compensate for the reduction of the diameter (D3) of the upper and lower sprockets 32, 33, the suspension position 136 of the suspension material 35 (the axis of the suspension shaft 129) from the shaft cores C1, C2 of the upper and lower sprockets 32, 33. In order to make the distance L to the core) the same as the existing distance, the arm length (B3) of the suspension member 35 is increased to be the distance L.

  These are the main <modification items>. In this embodiment, the position of the axis C2 of the lower sprocket 33 is set to the same position as the existing one, and the distance H40 from the road surface 125 of the cage 116 landing on the loading portion 111 to the axis C2 of the lower sprocket 33 is set. Same distance as existing. That is, there is no change in the entry level. Therefore, since the flooring level of the cage 116 does not change, excavation of the floor (such as a pit) of the entry portion 111 and additional remodeling work such as a road slope deck are not required.

  Further, in order to make the total length of the main chain 114 the same as that of the existing vertical circulation parking device and the same number of accommodation as the existing one, if the diameter D3 of the upper and lower sprockets 32, 33 is reduced, the upper and lower sprockets 32, The distance between the shaft centers 33 becomes longer. Therefore, the extension corresponding to the extension of the distance between the shaft centers is absorbed by moving the position of the shaft core C1 of the upper sprocket 32 upward. Thereby, the distance from the upper surface of the receiving beam 118 to the axial center C1 becomes the distance H33. The amount of increase Δ3 (FIG. 4D) of the axis C1 of the upper sprocket 32 is Δ3 = π (D0−D3) / 2.

  Further, at the time of this modification, (the amount of increase Δ3 of the upper sprocket shaft C1) <(the lower surface of the ceiling beam 106 of the steel structure 105 from the upper end of the suspension member 115 in the existing vehicle-mounted cage 116 at the uppermost position. It is preferable to set a reduction in the number of meshing teeth of the upper and lower sprockets 32 and 33 so that the diameters of the upper and lower sprockets 32 and 33 are reduced within a range of the distance S0).

  The drive mechanism 117 that drives the upper sprocket 32 moved upward in this way has a base 39 that is raised between the front and rear receiving beams 118 since the receiving beam 118 is not modified. A gear transmission mechanism 142 is installed on the gantry 120 on the base 39. The change of the drive mechanism 117 corresponding to the change of the position of the axis C1 of the upper sprocket 32 may be dealt with by replacing the gear transmission mechanism 142 and the like with a new structure.

  Based on FIG. 3, the above described corner cut lap situation by the modified vehicle mounting cage 36 will be described by taking the lower inversion portion 135 as an example. This figure also shows the relative movement trajectory of the upper cage 36 in a state where the lower cage 36 that reversely moves is fixed. As shown in FIGS. 1 and 2, the number of meshing teeth of the upper and lower sprockets 32 and 33 is reduced to reduce the diameter, and the movement trajectory through which the vehicle-mounted cage 36 circulates is the same as that of the existing parking device main body 110. As a result of the modification, the space between the circulating cages 36 in the lower inversion portion 135 is wider than before, and the side of the chassis 126 of the upper cage 36 enters the upper left and right outer corners of the lower cage 36. Is smaller than the existing parking device main body 110, the corner cutting region R3 can be reduced accordingly. The same applies to the upper inversion unit 133.

  Therefore, as shown in FIG. 2, the vehicle accommodating area RV3 can be enlarged by the reduction of the corner cutting area R3, and thereby the vertical circulation type capable of accommodating the medium and high vehicle height M3. The parking device 51 can be modified. In other words, the height H53 from the outside rising portion of the vehicle road surface 125 of the vehicle-mounted cage 36 to the corner cut-off restricting member 141 (substantially equivalent to the vehicle height of a vehicle that can be accommodated) is the height of the existing vertical circulation parking device 101. Since it becomes higher than H50 (FIG. 10), it is possible to expand the number of vehicles accommodated so that medium and high vehicles M3 can be accommodated, thereby improving the parking efficiency. Table 1 shows a summary of these remodeling (dimension change) items and their correlation.

  4 (a) to 4 (e) show the upper and lower sprockets in the existing vertical circulation parking device and various modifications according to the present invention. FIG. 4 (a) is a diagram described above. FIG. 4B is an explanatory view showing the upper and lower sprockets in the existing vertical circulation parking device shown in FIGS. 9 and 10, and FIG. 4B is an upper and lower sprocket in the first modified example in the vertical circulation parking device shown in FIGS. FIG. 4 (c) is an explanatory view showing upper and lower sprockets of the second modified example of the vertical circulation parking device, and FIG. 4 (d) is a third modified vehicle of the vertical circulation parking device. FIG. 4E is an explanatory view showing the upper and lower sprockets of the fourth modified example of the vertical circulation parking apparatus. FIG. 5 is a front view of a part of the upper part of the vertical circulation parking apparatus showing the modification performed in addition to the modification of the vertical circulation parking apparatus shown in FIG. In these drawings, the same reference numerals are assigned to the above-described distances and the like.

  In the existing vertical circulation parking apparatus 101 shown in FIG. 4 (a), the case where the number of meshing teeth with which the main chain 114 of the upper and lower sprockets 112, 113 is engaged is "12" is shown. Has a diameter D0 and an interdental center angle of 30 °, and there is a gap S0 between the upper end of the suspension member 115 and the ceiling beam 106. Further, the vehicle accommodating area RV0 of the vehicle mounting cage 116 has a width W and a height H50.

  In the first modified example shown in FIG. 4B, the number of meshing teeth with which the main chain 114 of the upper and lower sprockets 12 and 13 is engaged is “11.5”. 23, the main chain 114 is engaged with every two teeth. In this example, the upper and lower sprockets 12 and 13 have a diameter D1, and the inter-tooth center angle with which the main chain 114 engages is about 31.3 °. Then, the axis C1 of the upper sprocket 12 rises by Δ1, and the suspension member 15 becomes longer to become the gap S1. As a result, the vehicle-mounted cage 16 becomes a corner cutting region R1, and the vehicle-accommodable region RV1 becomes wide with a width H that remains unchanged but a height H51. Therefore, it is possible to accommodate medium and high vehicles with the increase in the height H51.

  In the second modification shown in FIG. 4C, the number of meshing teeth with which the main chain 114 of the upper and lower sprockets 22 and 23 is engaged is “11”. In this example, the upper and lower sprockets 22, 23 have a diameter D2 and an interdental center angle of about 32.72 °. Then, the axis C1 of the upper sprocket 22 rises by Δ2, and the suspension member 25 becomes longer to become the gap S2. As a result, the vehicle-mounted cage 26 becomes a corner cutting region R2, and the vehicle-accommodable region RV2 becomes wide at a height H52 although the width W is unchanged. Therefore, it is possible to accommodate medium and high vehicles with the increase in the height H52.

  The third modified example shown in FIG. 4D shows a case where the number of meshing teeth with which the main chain 114 of the upper and lower sprockets 32 and 33 is engaged is “10”. This example is the example shown in FIGS. 1 and 2, and the upper and lower sprockets 32 and 33 have a diameter D3 and an interdental center angle of 36 °. Then, the axis C1 of the upper sprocket 32 rises by Δ3, and the suspension member 35 becomes longer to become the gap S3. As a result, the vehicle-mounted cage 36 becomes the corner cutting region R3, and the vehicle-accommodable region RV1 becomes wide at the height H53 although the width W is unchanged. Therefore, it is possible to accommodate medium and high vehicles with the increase in the height H53.

  In the fourth modified example shown in FIG. 4E, the number of meshing teeth with which the main chain 114 of the upper and lower sprockets 42 and 43 is engaged is set to “9”. In this example, the upper and lower sprockets 42 and 43 have a diameter D4 and an interdental center angle of 40 °. Then, the axis C1 of the upper sprocket 42 is raised by Δ4. As a result, the vehicle-mounted cage 46 becomes a corner cutting region R4, and the vehicle-accommodable region RV4 becomes wide at a height H54 although the width W remains unchanged. Therefore, with the increase in the height H54, it becomes possible to accommodate medium and high vehicles.

  However, in the case of this fourth modified example, the amount of increase Δ4 of the upper sprocket 42 by reducing the number of meshing teeth of the upper and lower sprockets 42, 43 and lengthening the suspension member 45 is the same as that of the existing vertical circulation parking system. It becomes larger than the clearance S between the upper end of the suspension material 115 in the apparatus 101 and the ceiling beam 106. Therefore, in the fourth modification example, as shown in FIG. 5, the ceiling is within the range of a multistory parking lot installation environment (clearance of slanted line restrictions, floor area ratio, etc.) in which modification of the ceiling beam 106 and the roof 107 part is permitted. The beam 106 and a part of the roof 107 are modified to move upward. Thereby, a clearance S4 is secured between the upper end of the suspension member 45 and the ceiling beam 106. Such remodeling of the ceiling part may be performed by raising a part or all of the structure according to the multi-story parking lot installation environment or the like.

  4 (a) to 4 (e), the diameters (D1 to D4) of the upper and lower sprockets 12, 13, 22, 23, 32, 33, 42, 43, and the ceiling beam 106 are shown. And the corner cutting regions (R1 to R4) of the vehicle-mounted cages 16, 26, 36, and 46 are sequentially reduced, and the arm lengths of the suspension members 15, 25, 35, and 45 ( B1 to B4), the vehicle mountable vehicle heights (H51 to H54), and the vehicle mountable regions (RV1 to RV4) of the vehicle mounting cages 16, 26, 36, and 46 increase in order. Further, other details in these modified examples are the same as those in FIGS.

  As described above, according to the above-described method for remodeling the vertical circulation parking apparatus, even the existing vertical circulation parking apparatus 101 constructed exclusively for low-height vehicles (ordinary sedan vehicles) Steel structure 105 with construction etc. (“steel structure” in this specification and claims includes the structure surrounding the parking device body such as a building building housing) is not remodeled. Can be modified to a vertical circulation parking device 51 that can accommodate medium- and high-height vehicles, and can improve the parking efficiency by expanding the number of vehicles accommodated. it can.

  Note that the reduction in the number of meshing teeth of the upper and lower sprockets 12, 13, 22, 23, 32, 33, 42, 43 in the above embodiment is an example, and is preferable according to the existing vertical circulation parking device 101. What is necessary is just to select a reduction number, and it is not limited to the said embodiment.
