Description

  The present invention relates to a mechanical parking apparatus, and more particularly to a method for remodeling a vertical circulation parking apparatus and a vertical circulation parking apparatus after modification.

  As a mechanical parking apparatus that operates by placing a vehicle on a pallet, an elevator system, a vertical circulation system, a multi-layer circulation system, a horizontal circulation system, a plane reciprocation system, a two-stage system, a multistage system, and the like are known.

  Among these, the vertical circulation type mechanical parking device (hereinafter referred to as “vertical circulation type parking device”) is called so-called tower parking, and a number of cages carrying automobiles are vertically moved like a carousel (or a Ferris wheel). It is a mechanical parking device that is rotated and moved in and out. In this vertical circulation parking device, the main chain is passed endlessly between the upper sprocket and the lower sprocket attached to the steel frame, which is the frame of the parking device, and a plurality of cages attached to this main chain are rotated vertically. It is comprised so that it may make it.

  The entrance and exit of the vertical circulation parking system is usually provided on the first floor, the upper sprocket is rotated by a motor, the main chain spanned between the upper and lower sprockets is raised and lowered, and the cage is moved to the first floor. By lowering, the loading and unloading is performed continuously and smoothly. In addition, the entrance / exit of the vertical circulation parking apparatus may be located in the middle or upper part of the vertical circulation parking apparatus.

  Many of the above-described vertical circulation parking devices have already been manufactured and used continuously. Many of the existing vertical circulation parking systems are for ordinary cars. The height of an ordinary vehicle is lower than 1550 mm. In order to store a vehicle having a vehicle height of 1550 mm, for example, an arrangement pitch in the vertical direction of the cage of about 1750 mm is required. Therefore, many arrangement pitches of the existing vertical circulation parking apparatus are set to about 1750 mm.

  In recent years, the proportion of ordinary cars in domestic passenger cars is about 40%, and the rest are minivans and high roof cars. Minivans and high roof cars cannot be stored in the existing vertical circulation parking system because they are higher than ordinary cars.

  Therefore, for example, Patent Documents 1 and 2 propose vertical circulation parking apparatuses that store minivans and high roof cars.

  In Patent Document 1, the attachment attached to the main chain is removed for every four links, and it is attached to every five links, so that it can be used to store a minivan or a high roof car. It is disclosed to modify the parking device.

  In addition, the vertical circulation parking apparatus disclosed in Patent Document 2 has an in-vehicle cage arranged at a 4.5 link pitch by alternately providing two types of attachments in the main chain. One attachment is a normal symmetrical attachment, and the other is an eccentric attachment in which the position of the support portion of the in-vehicle cage is different by a half link pitch.

JP2015-214871A JP 2004-225426 A

  The height of passenger cars increases in the order of ordinary cars, minivans, and high roof cars. Specifically, the height of a normal vehicle is less than 1550 mm, the height of a minivan is about 1550 to 1780 mm, and the height of a high roof vehicle is about 1780 mm or more.

  In order to modify the vertical circulation parking system so that a high roof car can be mounted, it is necessary to increase the distance between the attachments. For example, as in the modification method disclosed in Patent Document 1, if attachments are attached every five links, the distance between the attachments can be increased, and a high roof vehicle can be mounted.

  However, if the vertical circulation parking system for ordinary cars is modified to accommodate high-roof vehicles, the number of high-roof vehicles will be greatly reduced due to the high vehicle height.

  For example, if the number of stored vertical circulation parking devices is 26, the number of links in the existing main chain is 26 × 4 links = 104. In addition, when a modification is made to attach attachments every 5 links, only 104 attachments / 5 links≈20 attachments can be attached to the main chain, and the number of storage units is reduced by 6 units.

  On the other hand, of the passenger cars registered in Japan in recent years, the number of registered high roof cars is only about 15%. Ordinary vehicles account for about 40% of the number of registered vehicles, and minivans account for about 45%. For this reason, there is a need to increase the number of storage units of the vertical circulation parking device even if the high roof vehicle cannot be stored.

  Moreover, if the symmetrical attachment and the eccentric attachment disclosed in, for example, Patent Document 2 are attached to the existing main chain, cages can be arranged with a 4.5 link pitch, and it seems that the number of storage can be increased.

  However, when these attachments are alternately attached to the existing main chain and the vertical circulation parking device is modified, the rotational trajectories of the symmetric attachment and the eccentric attachment differ.

  In addition, the eccentric attachment is special and not commercially available, so it must be newly manufactured. For this reason, even if the rotation trajectories of the symmetric attachment and the eccentric attachment can be aligned, the modification of the vertical circulation parking apparatus by this method requires a large amount of money and is difficult to realize.

  The present invention has been developed to solve the above-described problems. In other words, an object of the present invention is to provide a vertical circulation parking device modification method and a modified vertical circulation parking device capable of increasing the number of ordinary vehicles and minivans stored compared to the conventional modification method of a vertical circulation parking device. There is to do.

It is a comparison block diagram of an existing cage and a new cage. It is a lower part enlarged view of FIG. 1 (B). FIG. 6 is a view taken along the line E-E in FIG. 4, showing the relationship between the linear guide, the new chain, the chain roller, and the new attachment. It is a flowchart of the remodeling method of the existing parking apparatus by this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

  FIG. 1 is an overall configuration diagram of an existing vertical circulation parking device 1 and a modified vertical circulation parking device 10. (A) is the existing vertical circulation parking apparatus 1, and (B) is the vertical circulation parking apparatus 10 after modification by the modification method of the present invention.

  FIG. 2 is an enlarged view of the lower part of FIG.

  In the following description, the remodeling method of the existing vertical circulation parking device 1 of the present invention is “the present remodeling method”, the existing vertical circulation parking device 1 is “existing parking device 1”, and the reverted vertical circulation parking device. 10 is a “modified parking device 10”.

  The present invention relates to a modification method for an existing parking device 1 that modifies the existing parking device 1 into a modified parking device 10 that can park a normal car and a minivan, and the modified parking device 10. The minivan is a vehicle having a vehicle height higher than that of a normal vehicle and lower than that of a high roof vehicle, and the vehicle height is approximately 1550 to 1820 mm.

  In FIG. 1A and FIG. 2, the existing parking apparatus 1 includes an existing main chain 2, upper and lower existing sprockets 3, a plurality of existing attachments 4, a plurality of existing cages 6, and a linear guide 8.

  The existing parking device 1 is provided with an existing main chain 2 (hereinafter referred to as an existing chain 2) spanned endlessly between an upper existing sprocket 3a and a lower existing sprocket 3b attached to a steel frame or a frame that is a skeleton of the parking device, A plurality of existing cages 6 attached to the existing chain 2 are configured to rotate in the vertical direction. Hereinafter, the upper existing sprocket 3 a and the lower existing sprocket 3 b are collectively referred to as an existing sprocket 3.

  The existing chain 2 is stretched between the upper existing sprocket 3a and the lower existing sprocket 3b.

  A plurality of existing attachments 4 are attached to the existing chain 2 for each of a plurality of links constituting the existing chain 2. In the example of FIGS. 1A and 2, the existing attachment 4 is attached to the existing chain 2 every four links. Accordingly, the plurality of existing attachments 4 are attached to the existing chain 2 with a first interval P1 therebetween.

  The plurality of existing cages 6 are suspended from the outer end 4 a of the existing attachment 4.

  The straight guide 8 guides the inner end 4b of the existing attachment 4 so as to be movable in the vertical direction.

  For example, the shaft 7 of the existing cage 6 shown in FIG. 3A to be described later is rotatably provided on the outer end 4 a of the existing attachment 4. The existing cage 6 is attached to the existing chain 2 by supporting both ends of the shaft 7 on the outer end 4 a of the existing attachment 4.

  The existing linear guide 8 is attached to, for example, a steel frame or a casing that is a skeleton of the parking apparatus, and has a pair of planes extending in parallel in the vertical direction. The straight guide 8 may be, for example, a grooved steel or an H-shaped steel that extends vertically. A pair of the linear guides 8 may be provided with the existing sprocket 3 interposed therebetween. However, the configuration of the linear guide 8 may be other than this.

  The linear guide 8 sandwiches the chain roller 9 of the existing chain 2 between a pair of opposed planes, and limits the movable range of the chain roller 9 in the vertical direction.

  With this configuration, the linear guide 8 indirectly guides the inner end 4b of the existing attachment 4 through the chain roller 9 so as to be movable in the vertical direction.

  The existing parking device 1 described above is intended for a normal vehicle, and the vertical arrangement pitch (first interval P1) of the existing cage 6 is set to 1750 mm, for example. Considering the frame of the existing cage 6, the thickness of the pallet 20, and the like, the existing cage 6 can store a normal vehicle having a vehicle height of up to 1550 mm. That is, in this example, the existing cage 6 is a cage for vehicles with a low vehicle height.

  In this example, the first interval P1 is configured by four existing links 2a, and the length of one existing link 2a is, for example, about 400 to 440 mm.

  FIG. 3 is a comparative configuration diagram of the existing cage 6 and the new cage 16. In this figure, (A) is a front view of the existing cage 6, (B) is a front view of the new cage 16, and (C) is a side view of the new cage 16. The new cage 16 can store ordinary cars and minivans. In other words, the distance from the height of the upper surface (mounting surface 22) of the pallet 20 mounted on the new cage 16 to the inside of the frame of the new cage 16 is higher than the vehicle height of the minivan and lower than the vehicle height of the high roof vehicle. A new cage 16 is configured.

  Both the existing cage 6 and the new cage 16 have shafts 7 and 17 that are rotatably attached to the outer end portions 4 a and 14 a of the existing attachment 4 or the new attachment 14. Hereinafter, the height from the lower end of the shaft 7 of the existing cage 6 to the mounting surface 22 on which the vehicle is mounted is referred to as a first height H1, and the height from the lower end of the shaft 17 of the new cage 16 to the mounting surface 22 is the second height. Call it H2. The second height H2 is higher than the first height H1 by the modified height ΔH. For example, the second height H2 is set to, for example, 1790 to 1820 mm so that a minivan can be placed.

  “Modified height ΔH” is a difference (= H2−H1) between the second height H2 and the first height H1.

  As shown in FIGS. 3B and 3C, the new cage 16 has a pair of lifting portions 16a, a vehicle mounting portion 16b, and a pair of suspension frame portions 16c.

  The pair of lifting portions 16a are located at an interval in the front-rear direction.

  The vehicle mounting portion 16 b is located below the lifting portion 16 a and supports the pallet 20. The pallet 20 has a mounting surface 22 on which the vehicle is mounted on the upper surface.

  The pair of suspension frame portions 16c have openings through which the vehicle passes in the front-rear direction, and connects the lifting portion 16a and the vehicle mounting portion 16b.

  FIG. 3A shows the existing cage 6.

  As shown in FIG. 3B, the new cage 16 has a shaft 17 having the same dimensions as the shaft 7 of the existing cage 6, and the second height H2 from the shaft 17 to the mounting surface 22 on which the vehicle is mounted is It is different in that it is higher than the first height H1 of the existing cage 6 by a modified height ΔH.

  In other respects, the lifting portion 16a, the vehicle mounting portion 16b, and the hanging frame portion 16c of the new cage 16 are the same as the lifting portion 6a, the vehicle mounting portion, and the hanging frame portion 6c of the existing cage 6.

  With the above-described configuration, a minivan and an ordinary vehicle can be placed on the new cage 16.

  FIG. 4 is an enlarged view of the lower part of FIG.

  As shown in FIG. 4, the modified parking apparatus 10 includes a new chain 12, a new sprocket 13, a new attachment 14, a new cage 16, and a pair of existing linear guides 8.

  The new chain 12 is a chain having a pitch larger than that of the existing chain 2, and a new attachment 14 is attached to every four links equal to the number of links of the existing chain 2. In addition, as shown in FIG. 4, you may increase one new link 12a between some new attachments. For example, in FIGS. 1 and 4, there are 5 links between the bottom and the new cage 16 on the left and between the top and the new cage 16 on the right. A new attachment 14 is attached. In this case, the new link 12a to be added is preferably an offset link. The offset link is a link having one end connected to the outside of an adjacent link and the other end connected to the inside of a link adjacent to the opposite side.

  The new sprocket 13 includes a new upper sprocket 13a and a lower sprocket 13b. Hereinafter, the new upper sprocket 13a and the lower sprocket 13b will be referred to as the upper new sprocket 13a and the lower new sprocket 13b, respectively.

  The interval between the teeth of the new sprocket 13 is larger than that of the existing sprocket 3 in accordance with the pitch of the new chain 12.

  For example, as illustrated in FIG. 3C, the shaft 17 of the new cage 16 is rotatably provided on the outer end portion 14 a of the new attachment 14. The new cage 16 is attached to the new chain 12 by supporting both ends of the shaft 17 on the outer end portion 14 a of the new attachment 14.

  FIG. 5 is an EE arrow view of FIG. 4 showing the relationship between the linear guide 8, the new chain 12, the chain roller 19, and the new attachment 14. As shown in FIG.

  The existing linear guide 8 sandwiches the chain roller 19 of the new chain 12 between the pair of opposed planes described above, and limits the movable range of the chain roller 19 in the vertical direction. The chain roller 19 is attached to the inner end 14 b of the new attachment 14. With this configuration, the linear guide 8 also guides the outer end portion 14a of the new attachment 14 via the chain roller 19 so as to be indirectly movable in the vertical direction.

  The pair of existing linear guides 8 is the same as that provided in the existing parking device 1 and is attached to the modified parking device 10.

  The modified parking device 10 uses the existing linear guide 8 used in the existing parking device 1 as it is or while shifting the position in the vertical direction. This makes it possible to provide a cheaper and faster vertical circulation parking device that can park a minivan than when a new vertical circulation parking device is rebuilt from scratch.

  For example, in the example of FIG. 4, the new attachment 14 has a V shape. The new attachment 14 has both end portions 14b (that is, the inner end portion 14b) rotatably connected to both end portions of the new link 12a, and protrudes outward from the new chain 12 in a V-shape. The new attachment 14 is provided such that the angle formed by the arm 14c connecting the both end portions 14b and the outer end portion 14a is larger than that of the existing attachment 4. Thus, the outer end portion 14a of the new attachment 14 is provided at a position where the new cage 16 can be suspended.

  That is, in the width direction of the existing cage 6, the width W1 of the locus T1 drawn by the outer end portion 4a of the existing attachment 4 and the width W2 of the locus T2 drawn by the outer end portion 14a of the new attachment 14 have the same length. can do. Thereby, even if the pitch of the new chain 12 is different from that of the existing chain 2, the width W <b> 2 of the trajectory T <b> 2 can be stored without changing from the existing parking device 1.

  In this way, the inner end portion 14b of the new attachment 14 is guided by the existing linear guide 8 attached to the new parking device 10 so as to be movable in the vertical direction.

  FIG. 6 is a flowchart of this remodeling method. In this figure, this remodeling method consists of each step (process) of S1-S5.

  In step S1, the new sprocket 13, the new main chain 12 (hereinafter, new chain 12), the new attachment 14, and the new cage 16 are prepared.

  The chain link of the new chain 12 (hereinafter, the new link 12a) is provided with a larger pitch than the existing chain 2. The pitch of the new link 12a is, for example, about 470 to 490 mm, and preferably 480 mm. However, the pitch length of the new link 12a is not limited to this. The pitch length of the new link 12a is a value obtained by dividing the distance between attachments necessary for the modified parking apparatus 10 to store the target vehicle by the predetermined number of links. The predetermined number of links is preferably the same as the number of links of the existing parking apparatus 1, but is not limited thereto.

  For example, when the first interval P1 is composed of four existing links 2a and the length of one existing link 2a is, for example, about 437.5 mm, the first interval P1 is about 1750 mm.

  In addition, as described above, in the conventional case where attachments are attached to every five links of the existing chain 2, the distance between the attachments is 437.5 mm × 5 = 2187.5 mm.

  Here, it is assumed that the arrangement pitch in the vertical direction of the new cage 16 is the second interval P2. When the second interval P2 is composed of four new links 12a and the length of one new link 12a is about 480 mm, for example, the second interval P2 is about 480 mm × 4 = about 1920 mm.

  Accordingly, the new cage 16 having the second height H2 (for example, 1790 to 1820 mm) can be suspended at the second interval P2.

  Thereby, this invention can shorten the distance between attachments rather than the case where an attachment is attached for every 5 links of the existing chain 2. FIG. Therefore, since the newly installed cage 16 can be packed and arranged compared to the conventional modification method in which attachments are attached every five links, the number of stored modified parking devices 10 can be increased.

  In step S2, the existing cage 6, the existing attachment 4, the existing chain 2, and the existing sprocket 3 are removed from the existing parking apparatus 1. After that, the newly installed upper sprocket 13a and lower sprocket 13b are attached to a steel frame or a casing that is a skeleton of the parking apparatus.

  The new sprocket 13 is preferably mounted at a position higher than the existing sprocket 3 by the modified height ΔH. In this case, the existing linear guide 8 is reattached to a position higher than the existing parking device 1 by the modified height ΔH.

  Thereby, a vehicle can be stored / extracted without changing the entrance / exit height from the existing parking apparatus 1.

  However, the present invention is not limited to this, and the vehicle may be allowed to enter and exit the new cage 16 by lowering the floor by the modified height ΔH.

  In addition, the length of the new chain 12 is made shorter than that of the existing chain 2, and only the lower new sprocket 13b is attached at a position higher than the lower existing sprocket 3b by a modified height ΔH, so that the entrance / exit height before and after the modification is the same. You may make it high.

  In step S3, the new chain 12 is passed endlessly between the upper new sprocket 13a and the lower new sprocket 13b, and the existing chain 2 is replaced with a new chain 12 having a larger pitch. As a result, the new chain 12 rotates in the vertical direction by the rotation of the new sprocket 13.

  The lengths of the new chain 12 and the existing chain 2 are preferably substantially the same or close. For example, in the example shown in FIG. 1B, the length of the new link 12a is 480 mm, and the length of the new chain 12 is about 46 m. For example, in the case of FIG. 1A, the length of the existing link 2a is 437.5 mm, and the length of the existing chain 2 is about 45.5 m.

  In step S <b> 4, the new attachment 14 is attached to the new chain 12 for every four links that are the same as the number of links between the existing attachments in the existing chain 2. At this time, the new attachment 14 is positioned so that its inner end portion 14 b can be guided by the existing linear guide 8.

  In the above example, since the number of links between the existing attachments of the existing chain 2 is four, the new attachments 14 are attached to the new chain 12 for every four links. The second interval P2 between the new attachments is 1920 mm.

  As a result of this modification, the number of stored parking devices 1 is 26, whereas the number of stored parking devices 10 is 24. On the other hand, the number of units that can be stored in the vertical circulation parking apparatus 1 after the modification that attaches the attachment to the existing chain 2 every five links as in the conventional modification method is 20.

  Therefore, by this remodeling method, the number of remodeling parking apparatuses 10 can be stored four more in the above-mentioned example than by the conventional remodeling method. Thus, this remodeling method can increase the number of storage units compared with the conventional remodeling method.

  Next, in step S5, the existing cage 6 is replaced with a new cage 16 for a vehicle having a higher vehicle height. The shaft 17 of the new cage 16 is suspended from the outer end portion 14a of each new attachment 14 attached to the new chain 12. As a result, the chain roller 19 moves along the linear guide 8 as the new chain 12 rotates.

  In FIG. 1B and FIG. 4, the modified parking apparatus 10 includes a new chain 12, a plurality of new attachments 14, and a plurality of new cages 16. The straight guide 8 is attached to a position higher than the existing parking apparatus 1 by a modified height ΔH.

  Therefore, the new cage 16 can be mounted with a normal car and a minivan. Thereby, since the remodeled parking apparatus 10 becomes possible [storing a minivan with high needs], it can respond to 85% or more of the vehicles registered.

  According to the above-described method and apparatus of the present invention, the main chain is replaced with the new chain 12 having a larger pitch than the existing chain 2, and the new attachment 14 and the new cage 16 are provided for every four links equal to the number of links of the existing parking device 1. Install. As a result, since the new cage 16 can be packed and arranged, the number of remodeled parking devices 10 that can be accommodated can be increased as compared with the conventional remodeling method in which attachments are attached to the existing chain 2 for every five links.

  Further, since the interval between the new attachments can be made longer than that of the existing attachment 4, the new cage 16 capable of mounting a vehicle having a vehicle height higher than that of the existing cage 6 can be attached to the new attachment 14.

  Moreover, since the shape of the new attachment 14 is a general V-shape and does not need to be specially ordered and manufactured, a commercially available attachment can be used as the new attachment 14. Therefore, the present invention can reduce the cost of remodeling because the new attachment 14 is cheap. Furthermore, since all the new attachments 14 included in one modified parking apparatus 10 have the same shape, the rotation trajectories of all the new attachments 14 are aligned, and the vertical circulation parking apparatus 1 can be easily modified.

  In addition, the existing steel frame, building, and linear guide 8 that will be the skeleton of the parking device are also used in the modified parking device 10, so that it does not require manufacturing costs, transportation costs, and construction costs, so that a new vertical circulation parking device is rebuilt. It is possible to provide a vertical circulation parking device that can park minivans at low cost. In addition, since remodeling is performed using a steel frame or building that has already been assembled, the construction period can be shortened by the amount that the assembly work is unnecessary.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
