Description

  The present invention relates to a vertical circulation parking apparatus and a modification method thereof.

  As an example of a parking device, a vertical circulation parking device is known in which a plurality of vehicles can be stored in a tower-like parking tower. As is well known, this type of vertical circulation parking device includes a drive sprocket and a driven sprocket that are spaced apart in the vertical direction, an annular transport chain wound between the upper and lower sprockets, and the transport chain. The vehicle transport cage is provided at a predetermined interval.

  As shown in FIG. 3C, a predetermined number of equal-length links 22 are connected to the transport chain 20 ′, and attachments 26 are provided on the equal-length links 22 at predetermined intervals. The transport cage 28 '(the height H1 of the storage unit) is suspended. Here, for example, four equal-length links 22 constitute one link group LG ', and one attachment 26 is provided for each link group LG'. The length of each equal-length link 22 is set so as not to generate a wasteful empty space between the respective vehicle transport cages 28 ′ so that even one vehicle can be accommodated.

  In recent years, with the increase in demand for minivans and SUV type passenger cars, passenger cars with a high vehicle height are on the rise. In a vertical circulation parking apparatus constructed several decades ago when there were few such vehicles, a low-height vehicle transport cage 28 'that can accommodate only a relatively low-sediment sedan car is used as a vehicle with a high vehicle height. Remodeling to replace the vehicle transport cage 28 with a high overall height that can also accommodate the vehicle is proceeding.

  As an example of the modified parking device, as shown in FIG. 3 (d), the number of equal-length links 22 in the link group LG ′ is increased from, for example, four to five to form a link group LG ″. 26, the vehicle conveyance cage 28 '(storage unit height H1) having a low overall height is replaced with a vehicle conveyance cage 28 (storage unit height H2) having a high overall height.

  However, in the parking apparatus using the link group LG ″ in which the number of the isometric links 22 is simply increased by one, it is not possible to flexibly cope with the height of the new vehicle transport cage 28 having a high overall height. As shown in FIG. 3 (d), a useless empty space ΔH is generated between the vehicle transport cages 28, thereby causing a problem that the number of parked cars after remodeling is reduced.

  Therefore, in Patent Document 1, it is possible to adjust and set the distance between the vehicle transport cages relatively freely by newly using two types of links having different link pitches and upper and lower sprockets meshing with these two types of links. It was.

Japanese Patent No. 4592678

  However, the upper and lower sprockets newly used in Patent Document 1 need to increase the number of teeth as compared with the sprocket before replacement, and it is assumed that the manufacturing cost increases and the workability on site is deteriorated.

  The present invention has been made in view of such circumstances, and a vertical circulation type parking device that has a vehicle conveyance cage having different heights and efficiently secures the number of parked vehicles can have a simple structure. A remodeling method for a parking system and a vertical circulation parking system is provided.

In order to solve the above problems, the vertical circulation parking apparatus and the remodeling method thereof employ the following means.
That is, the vertical circulation parking apparatus according to one aspect of the present invention includes a drive sprocket that is rotationally driven by an electric motor, a driven plate that is spaced apart in the vertical direction with respect to the drive sprocket, the drive sprocket, and the driven A vertical circulation parking apparatus comprising: a transport chain wound between plates and having a plurality of link groups each having a predetermined number of links connected thereto; and a vehicle transport cage suspended for each link group, The link group includes an equal length link having an equal pitch, and a different pitch link having a different pitch from the equal length link, and the drive sprocket meshes with the equal length link and the different pitch link, and the driven plate The outer peripheral surface is not cut into teeth.

The transport chain is configured by a link group including a predetermined number of equal length links and different pitch links having different pitches from the equal length links. The drive sprocket is a sprocket that meshes with an equal-length link and a different pitch link. As a result, the pitch of the link group can be adjusted. For example, the adjustment conventionally performed in units of Xmm (corresponding to a pitch of one link) can be adjusted in units of about 0.5Xmm. This prevents unnecessary space from being generated between each vehicle transport cage when a vehicle transport cage with a high overall height is attached to the transport chain as compared to the case of using a transport chain composed of all equal length links. And the decrease in the number of parking can be minimized.
The driven plate was a plate whose outer peripheral surface was not chopped. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate has an outer diameter smaller than that of a normal driven sprocket in which teeth are formed, the weight can be reduced and the transportability can be improved. In addition, since the engagement with the chain is eliminated, on-site workability can be improved.

  In the vertical circulation parking apparatus according to one aspect of the present invention, the driven plate is a disk-shaped circular plate.

  The driven plate was a disc-shaped circular plate. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate has an outer diameter smaller than that of the driven sprocket, the weight can be reduced and the transportability can be improved. In addition, since the engagement with the chain is eliminated, on-site workability can be improved.

  In the vertical circulation parking apparatus according to one aspect of the present invention, a groove for applying a frictional force to the transport chain is provided on the outer peripheral surface of the driven plate.

  On the outer peripheral surface of the driven plate, a groove for applying a frictional force to the transport chain is provided. Thereby, it can suppress that a driven plate slides with respect to a link, and can suppress wear of a link (especially link connection part). Further, by suppressing sliding, chatter vibration between the driven plate and the link can be suppressed, and as a result, noise generated by the vibration can be reduced.

  In the vertical circulation parking apparatus according to the reference example of the present invention, the driven plate is a polygonal plate.

  The driven plate was a polygonal polygon plate. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate has an outer diameter smaller than that of the driven sprocket, the weight can be reduced and the transportability can be improved. Further, since the engagement with the chain is eliminated, it is possible to realize low noise and improve on-site workability. Furthermore, since the driven plate is polygonal, it is possible to suppress the driven plate from sliding relative to the link.

  In the vertical circulation parking apparatus according to the reference example of the present invention, the driven plate has a polygonal shape having a number of angles corresponding to the number of teeth of the drive sprocket.

  The driven plate was a polygonal polygon plate having a number of angles corresponding to the number of teeth of the drive sprocket. Thereby, since a link (link connection part) contacts only the fixed position of one side of a driven plate, the location which quenches can be specified and the reduction of manufacturing cost can be aimed at.

  The vertical circulation parking apparatus according to an aspect of the present invention includes a tension adding mechanism that applies tension to the transport chain.

  A tension adding mechanism is provided. Thereby, it is possible to prevent damage to the transport chain due to noise, wear, tooth skipping, and tooth skipping caused by the slack of the transport chain.

  A method for remodeling a vertical circulation parking apparatus according to an aspect of the present invention includes a drive sprocket that is rotationally driven by an electric motor, a driven sprocket that is provided vertically apart from the drive sprocket, the drive sprocket, A transport chain formed by connecting a plurality of link groups each having a predetermined number of equal length links wound between the driven sprockets and having an equal pitch; and a vehicle transport cage suspended from each link group. A vertical circulation parking device modification method comprising a plurality of link groups having different pitch links different in pitch from the isometric links, and engaging the drive sprocket with the equal length links and the different pitch links. , Replace the sprocket with more teeth than the drive sprocket, the driven sprocket, Toothed exchanges the driven plate that is not subjected to the peripheral surface.

In a link group constituted by a predetermined number of equal length links, different pitch links having different pitches from the equal length links are provided. In addition, the drive sprocket is replaced with a drive sprocket that meshes with the isometric link and the different pitch link. As a result, the pitch of the link group can be adjusted. For example, the adjustment conventionally performed in units of Xmm (corresponding to a pitch of one link) can be adjusted in units of about 0.5Xmm. This prevents unnecessary space from being generated between each vehicle transport cage when a vehicle transport cage with a high overall height is attached to the transport chain as compared to the case of using a transport chain composed of all equal length links. In addition, the reduction in the number of parked cars after remodeling can be minimized.
In addition, the driven sprocket was replaced with a driven plate having no teeth. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate has an outer diameter smaller than that of the driven sprocket, the weight can be reduced and the transportability can be improved. In addition, since the engagement with the chain is eliminated, on-site workability can be improved.

  According to the vertical circulation parking apparatus according to the present invention, the transport chain is configured by a chain group including an equal length link and a different pitch link, and the drive sprocket is a sprocket that meshes with the equal length link and the different pitch link, and is further driven. By using a plate that has no teeth on the outer peripheral surface, the vertical circulation parking apparatus that includes vehicle transport cages of different heights and efficiently secures the number of parked vehicles can have a simple structure.

It is a longitudinal cross-sectional view of the vertical circulation parking apparatus which can be modified to the vertical circulation parking apparatus according to the present invention. It is the figure which showed the driven plate and conveyance chain which concern on reference embodiment of this invention.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

[First Embodiment]
As shown in FIG.1 and FIG.2, this vertical circulation type parking apparatus 1 is capable of accommodating a plurality of vehicles, and includes a parking tower 2 in which a vehicle entrance / exit 3 (see FIG. 2) opens on the ground. ing.

  The parking tower 2 has a structure in which a lightweight concrete plate is installed on the outer surface of a frame made of, for example, a steel frame, and an inside of the entrance / exit 3 is a entrance room 4 into which a vehicle enters. In addition, the entrance / exit 4 (entrance / exit 3) is not necessarily provided in the lowest part of the parking tower 2, and may be provided in the middle part or the uppermost part of the parking tower 2 (in the case of an underground type etc.).

  A driving sprocket 10 driven by an electric motor 14 is pivotally supported above the parking tower 2 in the vertical direction. Corresponding to the drive sprocket 10, a driven plate 12A is pivotally supported below the vertical direction. The driven plate 12A is pivotally supported so as to be free to rotate around the central axis.

  An endless annular transport chain 20 is wound between the drive sprocket 10 and the driven plate 12 to form an elliptical circulation path extending in the vertical direction.

  As shown in FIG. 3A, the transport chain 20 is configured such that a predetermined number of links (5 in this embodiment) are rotatably connected by a link connecting portion 25 including pins, bushes, and rollers. A link group LG is formed, and a plurality of the link groups LG are connected. Further, in the present embodiment, among the five links, four equal-length links 22 having an equal pitch (Xmm) and different pitch links having a shorter pitch (about 0.5Xmm) than the equal-length links 22 are provided. 24 is one. That is, the link group LG has a pitch of about 4.5 X mm.

  In addition, as shown in FIG.3 (b), three equal-length links 22 made into equal pitch (Xmm) among four links, and a pitch (about 1.5Xmm) longer than equal-length links 22 are used. The number of different kinds of pitch links 24 may be one. In this case as well, the link group LG has a pitch of about 4.5 × mm.

  In the link group LG, a vehicle transport cage 28 (the height H2 of the storage unit) having a high overall height is suspended from each link group LG via an attachment 26, and the vehicle can be stored in the vehicle transport cage 28. . Thus, the link group LG means a set of a predetermined number of links 22 and 24 provided between adjacent attachments 26.

  The drive sprocket 10 shown in FIG. 1 includes teeth that mesh with the isometric links 22 and the different pitch links 24. For example, in the embodiment shown in FIG. 3A, one tooth meshes between the link connecting portions 25 of the different pitch links 24, and two teeth mesh between the link connecting portions 25 of the equal-length links 22. It has a structure.

  FIG. 4 shows the driven plate 12A of the present embodiment. Unlike the drive sprocket 10, the driven plate 12A is a disc-shaped circular plate with no teeth formed on its outer peripheral surface. That is, the driven plate 12 </ b> A rotates by frictional force with the transport chain 20 without meshing with the links 22 and 24 included in the transport chain 20.

  A vehicle that has entered the entrance room 4 from the entrance / exit 3 is stored in the vehicle transport cage 28 in the entrance room 4. The vehicle transport cage 28 is suspended from an attachment 26 provided in the transport chain 20 wound between the drive sprocket 10 driven by the electric motor 14 and the driven plate 12 </ b> A, and is accompanied by the rotation of the drive sprocket 10. It rises (lowers) due to the circulation of the transport chain 20. At this time, the vehicle transport cage 28 is suspended from the attachment 26 so as to maintain the horizontal direction of the stored vehicle. In this way, the vehicle is stored in the parking tower 2.

FIG. 5 shows an example of a vertical circulation parking device that can be modified to the vertical circulation parking device 1 according to the present embodiment.
In addition, in the vertical circulation parking apparatus 1 according to the present embodiment and an example of a vertical circulation parking apparatus that can be modified, the forms of the conveyance chain 20, the drive sprocket 10, the driven plate 12, and the vehicle conveyance cage 28 are different. The other points are the same. Therefore, only different points from the vertical circulation parking apparatus 1 according to the present embodiment will be described, and the other points will be omitted using the same reference numerals.

  A drive sprocket 10 ′ driven by an electric motor 14 is pivotally supported above the parking tower 2 in the vertical direction. A driven sprocket 16 is pivotally supported below the vertical direction corresponding to the drive sprocket 10 '.

  As shown in FIG. 3 (c), the transport chain 20 ′ is formed by connecting a plurality of link groups LG ′ composed of a predetermined number (for example, four) of equal-length links 22 (pitch is Xmm). Is formed. That is, the pitch as the link group LG ′ is 4 × mm. The drive sprocket 10 ′ and the driven sprocket 16 have teeth that mesh with the isometric link 22. Specifically, a structure is adopted in which one tooth meshes between the link connecting portions 25 of the equal-length link 22.

  For each link group LG ', a vehicle transport cage 28' having a low overall height (the height H1 of the storage unit) is suspended via the attachment 26, and the vehicle can be stored in the vehicle transport cage 28 '.

  A method of remodeling the above-described vertical circulation parking apparatus that can be modified to the vertical circulation parking apparatus 1 according to the present embodiment is as follows.

  As shown in FIG. 3A, a link group LG is formed by adding one heterogeneous pitch link 24 having a shorter pitch (about 0.5 × mm) than the equal length link 22 to the link group LG ′. That is, the pitch as the link group LG is about 4.5 × mm. A vehicle transport cage 28 having a high overall height is suspended from the attachment 26 provided in the extended link group LG to secure the height of the storage portion of the vehicle transport cage 28.

  Note that, as shown in FIG. 3B, among the four links, the equal-length links 22 having an equal pitch (X mm) are changed to three, and the pitch (about 1.. One heterogeneous pitch link 24 may be added. In this case as well, the link group LG has a pitch of about 4.5 × mm.

  Further, the drive sprocket 10 ′ is engaged with the equal-length link 22 and the different pitch link 24 and is replaced with the drive sprocket 10 having more teeth than the drive sprocket 10 ′. Specifically, in the case of the present embodiment, the drive sprocket 10 in which one tooth meshes between the link connecting portions 25 of the different pitch links 24 and two teeth mesh between the link connecting portions 25 of the equal-length links 22. Replace with.

  Further, the driven sprocket 16 is replaced with a driven plate 12 having no teeth formed on the outer peripheral surface.

According to this embodiment, the following effects are produced.
The transport chain 20 is configured by a link group LG including a predetermined number of equal length links 22 and different pitch links 24 having different pitches from the equal length links 22. The drive sprocket 10 is a sprocket that meshes with the equal-length link 22 and the different pitch link 24. Thereby, the pitch of the link group LG can be adjusted. For example, the adjustment conventionally performed in units of Xmm (corresponding to a pitch of one link) can be adjusted in units of about 0.5Xmm. As a result, compared to the case where the transport chain 20 composed of all the equal length links 22 is used, when a vehicle transport cage 28 having a high overall height is attached to the transport chain 20, there is a useless space between the vehicle transport cages 28. This can be prevented and the decrease in the number of parking can be minimized.

  The driven plate 12A was a plate with no teeth formed on the outer peripheral surface. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate 12A has an outer diameter smaller than that of a normal driven sprocket 16 in which teeth are omitted, the weight can be reduced and the transportability can be improved. In addition, since the meshing with the transport chain 20 is eliminated, the on-site workability can be improved.

  A groove or a pattern for applying a frictional force to the transport chain 20 may be provided on the outer peripheral surface of the driven plate 12A. Thereby, it is possible to suppress the driven plate 12A from sliding relative to the links 22 and 24, and to suppress wear of the links 22 and 24 (particularly the link connecting portion 25). Further, by suppressing the sliding, the occurrence of chatter vibration between the driven plate 12A and the links 22 and 24 can be suppressed, and as a result, noise generated by the vibration can be reduced.

[Reference embodiment]
Next, the vertical circulation parking apparatus 1 according to the reference embodiment of the present invention will be described. The present embodiment is different from the first embodiment in the form of the driven plate 12, and the other points are the same. Therefore, only different points from the first embodiment will be described, and the other parts are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 6 shows the driven plate 12B of the present embodiment. Unlike the drive sprocket 10, the driven plate 12B is a polygonal plate with no teeth formed on its outer peripheral surface. That is, the link connection part 25 of the links 22 and 24 is in contact with the side of the polygonal plate without meshing with the link included in the transport chain 20, thereby rotating the driven plate 12B.

According to this embodiment, the following effects are produced.
The driven plate 12B was a polygonal polygon plate. Thereby, it is not necessary to cut gears on the driven side, and the production cost can be reduced. Further, since the driven plate 12B has an outer diameter smaller than that of the driven sprocket 16 because the tooth is omitted, weight reduction and improved transportability can be realized. In addition, since the meshing with the transport chain 20 is eliminated, it is possible to realize low noise and improve on-site workability. Furthermore, since the driven plate 12B has a polygonal shape, the driven plate 12B can be prevented from sliding relative to the link.

  The driven plate 12B may have a polygonal shape having a number of angles corresponding to the number of teeth of the drive sprocket 10. Thereby, since the links 22 and 24 (link connection part 25) contact only the fixed position of 1 side of the driven plate 12B, the location which hardens can be specified, and reduction of manufacturing cost can be aimed at.

  In the first and reference embodiments, a tension adding mechanism that applies tension to the transport chain 20 may be provided. Thereby, it is possible to prevent damage to the transport chain due to noise, wear, tooth skipping, and tooth skipping caused by the slack of the transport chain. Furthermore, the number of equal-length links 22 and different pitch links 24 can be changed according to the target height of the vehicle transport cage. For example, five equal-length links 22 and one different pitch link 24 are used. Also good. Needless to say, the length of the different pitch link 24 can be changed as appropriate, and the number of teeth of the drive sprocket 10 is changed accordingly. Furthermore, the driven plate 12 is not limited to a solid plate, and may have a structure in which a part of the plate is hollowed out. In this case, the driven plate 12 can be further reduced in weight.
