TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation type parking device, and more particularly to a vertical circulation type parking device capable of relatively freely adjusting and setting a cage pitch in a main chain.
[0002]
[Prior art]
FIG. 8 is a diagram showing a coupling structure of an upper sprocket 102, a lower sprocket 103, and a main chain 104 in a conventional vertical circulation parking device 100A.
[0003]
The vertical circulation parking device 100A includes an upper sprocket 102 and a lower sprocket 103 attached to a building structure (tower: not shown), and a main chain 104 is hung between the two sprockets 102 and 103. ing. The supervisory chain 104 is formed by connecting a plurality of links, and a cage (not shown) for storing a car is suspended from some of the links. Here, the link on which the cage is suspended is referred to as a cage attachment link. In the figure, reference numeral 104a is assigned to the cage attachment link, and reference numeral 104b is assigned to the other links. The cage can be moved by rotating the upper sprocket 102 by a drive source (not shown) such as a motor.
[0004]
Both the upper sprocket 102 and the lower sprocket 103 have a diameter of about 1700 mm and 12 teeth. The link pitch is about 440 mm. In the supervisory chain 104, all the cage attachment links 104a are arranged at intervals of four links, so that the cage pitch (the interval between the tips of the projecting portions of the pair of adjacent cage attachment links 104a) is about 1760 mm. A cage having a height corresponding to the cage pitch can be attached to the cage attachment link 104a. In the structure of FIG. 8, the distance between the centers of the upper and lower sprockets 102 and 103 is about 7918 mm.
[0005]
On the other hand, in recent years, vehicles having relatively high vehicle heights have been increasing, and it is required that a vertical circulation type parking device be able to cope with such vehicles. For that purpose, it is necessary to increase the cage pitch so that a higher cage can be attached. Various methods can be considered to increase the cage pitch.
[0006]
Conventionally, a method of attaching cage attachment links attached at four link intervals in the main chain at five link intervals has been often adopted. In addition, as a method of modifying an existing vertical circulation type parking device so that a higher cage can be mounted, a method of changing a mounting link interval of a cage attachment link in a main chain has been proposed (for example, Patent Document 1).
[0007]
[Patent Document 1]
JP 2001-193301 A (pages 2 and 3; FIG. 1)
[0008]
[Problems to be solved by the invention]
As a method often used in the related art, a cage attachment link that has been attached at a four-link interval in the main chain can be attached at a five-link interval. Then, assuming that the link pitch is about 440 mm, the cage pitch can be increased from about 1760 mm to about 2200 mm.
[0009]
However, when it is not necessary to increase the cage height so much, it is not preferable to increase the cage pitch more than necessary because the number of cages that can be attached to the main chain is reduced.
[0010]
As another method for increasing the cage pitch, it is conceivable to slightly increase the link pitch. For example, when the link pitch is changed from about 440 mm to about 480 mm, the cage pitch can be increased from about 1760 mm to about 1920 mm when the cage attachment links are arranged at intervals of 4 links. In order to increase the link pitch from about 440 mm to about 480 mm while keeping the number of teeth of the upper and lower sprockets the same, the diameter of the sprocket must be changed. For example, to increase the link pitch from about 440 to about 480 mm while keeping the number of teeth of the sprocket at 12, the diameter of the sprocket must be increased from about 1700 mm to about 1855 mm.
[0011]
However, it is advantageous to keep the sprocket diameter similar to a conventional (existing) vertical circulation parking device. This is because much of the design documents and the like of a conventional (existing) vertical circulation type parking device can be used for a vertical circulation type parking device to be newly constructed. Also, when retrofitting an existing vertical circulation parking device to one having a larger cage pitch, it is advantageous to keep the sprocket diameter the same as the existing one.
[0012]
That is, if the diameter of the sprocket is increased, the dimensions must be changed not only in the vicinity of the sprocket in the tower, but also in many other places. In this case, the contents of the design documents and the like for the conventional (existing) vertical circulation type parking device cannot be efficiently used. In addition, remodeling is also a major task. This problem also occurs when the sprocket is changed to a small diameter. In other words, a structure that allows finer adjustment and setting of the cage pitch independent of the diameter of the sprocket is desirable.
[0013]
To accommodate longer link pitches while keeping the sprocket diameter similar to conventional (existing) vertical circulating parking devices, there is another way to change the number of sprocket teeth. That is, when the number of teeth of a sprocket having a diameter of 1700 mm is reduced from 12 to 11, the pitch of the link to be adapted is increased from about 440 mm to about 480 mm. When the cage attachment links are attached at intervals of four links, the cage pitch can be changed from about 1760 mm to about 1920 mm. However, if the number of teeth of the sprocket is reduced, the rotation of the main chain may impair the smoothness.
[0014]
On the other hand, it is conceivable to increase the number of teeth without changing the diameter of the sprocket. For example, increasing the number of teeth of a 1700 mm diameter sprocket from 12 to 13 reduces the matching link pitch from about 440 mm to about 406 mm. When the link interval of the cage attachment link is changed from 4 link intervals to 5 link intervals, the cage pitch can be changed from about 1760 mm to about 2030 mm. However, shortening the link pitch means shortening the length of the cage attachment link. Then, the reaction force of the rollers at both ends of the cage attachment link due to the load of the cage increases, and the load on the sprocket and the chain guide increases.
[0015]
Also, by changing only the number of teeth without changing the diameter of the sprocket, the cage pitch can be changed from about 1760 mm to about 1920 mm or about 2030 mm. Is difficult to change.
[0016]
The present invention can finely adjust and set the cage pitch independently of the diameter of the sprocket, and also prevents smooth rotation of the main chain and increases the reaction force of the rollers at both ends of the cage attachment link. It is an object of the present invention to provide a vertical circulation type parking device that does not cause the vehicle to be left.
[0017]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a vertical circulation type parking device according to the present invention has an upper sprocket attached to a building structure, a lower sprocket, and is stretched between the upper sprocket and the lower sprocket. What is claimed is: 1. A vertical circulation parking device comprising: a main chain; and a drive source for rotating the upper sprocket, wherein the main chain is formed by connecting a plurality of links, and one of the plurality of links is provided. Part is a first link, another part is a second link having a different pitch from the first link, and the first link meshes on the upper sprocket and the lower sprocket with the number of teeth, and the second link. The tooth spacing at which the link meshes on the upper sprocket and the lower sprocket is different (claim 1).
[0018]
According to this configuration, the upper and lower sprockets can mesh with at least two types of links (first link and second link) having different pitches. Depending on how the two types of links (the first link and the second link) are combined to form the supervisory chain, the cage pitch can be variously configured. Therefore, the cage pitch can be adjusted and set relatively freely independently of the diameter of the sprocket.
[0019]
In addition, it is not necessary to configure the main chain only with the first link and the second link. That is, the main chain may include links having different pitches from both the first link and the second link.
[0020]
In the above vertical circulation type parking device, at least a part of the first link is a cage attachment link, a pitch of the second link is smaller than a pitch of the first link, and the first link is the upper sprocket. The second link may be configured so that the number of teeth meshing on the upper sprocket and the lower sprocket is smaller than the number of teeth meshing on the lower sprocket (claim 2).
[0021]
In order to solve the above problem, another vertical circulation type parking device according to the present invention includes an upper sprocket attached to a building structure, a lower sprocket, and a hook between the upper sprocket and the lower sprocket. A vertical circulation parking device comprising: a passed main chain; and a drive source for rotating the upper sprocket, wherein the main chain is configured by connecting a plurality of links, and the plurality of links are connected to each other. Almost all of the links are links having the same pitch, and when N is an integer of 2 or more, the links of substantially all the numbers mesh with the upper sprocket and the lower sprocket at intervals of N teeth, and the upper sprocket And the number of teeth of the lower sprocket are not integral multiples of N (claim 3).
[0022]
According to such a configuration, not only the length (pitch) obtained by dividing the circumferential length of the upper and lower sprockets by an integer, but also links having various pitches can be used. Therefore, the cage pitch can be relatively freely adjusted and set independently of the diameter of the sprocket. Further, each tooth of the upper and lower sprockets does not mesh with the link every rotation, but meshes with the link only once every several rotations. Therefore, wear of the teeth is reduced. Here, "substantially all of the plurality of links are links having the same pitch" means that all of the links forming the main chain are links of the same pitch, and that the main chain is formed. This is intended to include both cases where not all but a number of links among the plurality of links are links having the same pitch.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Before describing an embodiment of the present invention, first, a description method of a sprocket and a main chain of a vertical circulation parking device will be described. FIG. 1 is a diagram for explaining this notation method.
[0024]
FIG. 1A is a diagram showing the lower sprocket 103 and the main chain 104 wrapped around it. The lower sprocket 103 has twelve teeth y formed on the periphery thereof. The supervisory chain 104 bridged over this is configured by a plurality of links 104a and 104b being connected endlessly via rollers r. Some of the links are T-shaped links 104a. The projecting portion of the T-shaped link 104a is for suspending the cage 108 at its tip. Such a link 104a is hereinafter referred to as a “cage attachment link”. The links 104b other than the cage attachment link 104a do not have an overhang like the cage attachment link 104a.
[0025]
FIG. 1B is a diagram showing the lower sprocket 103 and the main chain 104 having the same configuration as that of FIG. In FIG. 3 and subsequent figures, sprockets and main chains are represented by a notation as shown in FIG.
[0026]
In the above, the description method of the sprocket and the main chain of the vertical circulation type parking device has been described with reference to FIG.
[0027]
Next, an embodiment of the present invention will be described with reference to FIGS.
[0028]
FIG. 2 is a schematic external view of a vertical circulation parking device P according to an embodiment of the present invention. The building structure of the vertical circulation parking device P is the tower 1 as a steel structure.
[0029]
An upper sprocket 2 is attached to an upper part of the tower 1, and a lower sprocket 3 is attached to a lower part of the tower 1. The main chain 4 is stretched between the upper sprocket 2 and the lower sprocket 3. Further, a motor 5 as a drive source is attached to the upper part of the tower 1.
[0030]
The motor 5 and the upper sprocket 2 are connected by a gear mechanism. When the motor 5 is driven to rotate, the upper sprocket 2 is rotated, and the entire main chain 4 is stretched over the upper sprocket 2 and the lower sprocket 3. It is designed to rotate in a state. Reference numerals 6 and 7 denote gear boxes in which a gear mechanism for connecting the motor 5 and the upper sprocket 2 is housed. The front gear box 7 and the rear gear box 7 are connected by a shaft 9.
[0031]
FIG. 2 shows the cage 8 suspended from the supervisory chain 4 and at the lowest position (entry position). When the cage 8 comes to the lowermost position, the vehicle mounting surface 8a of the cage 8 is at substantially the same height position as the entry surface Q.
[0032]
A plurality of other cages are suspended from the main chain 4 of the vertical circulation parking device P, but they are omitted in FIG.
[0033]
FIG. 3 is a diagram showing a connection structure of an upper sprocket 2A, a lower sprocket 3A, and a main chain 4A, which can be applied to a parking device such as the vertical circulation type parking device P of FIG. In FIG. 3 (FIG. 3), the tower 1, the motor 5, and the like are omitted.
[0034]
The structure shown in FIG. 3 is a case where the existing vertical circulation type parking device 100A and its design as shown in FIG. 8 exist and are modified or modified so that a higher cage can be attached. In particular, the structure is particularly suitable.
[0035]
Referring to FIG. 3, the number of teeth of both the upper sprocket 2A and the lower sprocket 3A is 36. Both the upper sprocket 2A and the lower sprocket 3A have a diameter of about 1700 mm.
[0036]
The management chain 4A is configured by connecting a plurality of links 4a, 4b, 4c endlessly. The link 4a is a cage attachment link, and a cage (not shown) is hung at the tip thereof. The links 4b and 4c do not have an overhang as in the cage attachment link 4a. The pitch between the link 4a and the link 4b is the same, and is about 440 mm. The link 4c has a different pitch from the links 4a and 4b. The pitch of the link 4c is about 148 mm. When these links 4a, 4b, and 4c are classified by pitch, the links 4a and 4b can be classified as first links, and the link 4c can be classified as second links.
[0037]
As understood from FIG. 3, the links 4a and 4b mesh with the upper and lower sprockets 2A and 3A at intervals of three teeth. The link 4c meshes with the upper and lower sprockets 2A and 3A at intervals of one tooth.
[0038]
If the distance between the tips of a pair of adjacent cage attachment links 4a is referred to as "cage pitch", most cage pitches in the main chain 4A are about 1908 mm, but only one cage pitch is about 1760 mm. At a cage pitch of about 1908 mm, three links 4b and one link 4c are interposed between the cage attachment links 4a on both sides. At a cage pitch of about 1760 mm, three links 4b are interposed between the cage attachment links 4a on both sides thereof.
[0039]
Here, the coupling structure of FIG. 3 is compared with the coupling structure of FIG.
[0040]
3 and FIG. 8, the diameter of the upper and lower sprockets is about 1700 mm.
[0041]
In the structure of FIG. 3, most cage pitches are about 1908 mm, and in the structure of FIG. 8, all cage pitches are about 1760 mm.
[0042]
In the structure of FIG. 3, the pitch of the cage attachment links 4a is about 440 mm, and also in the structure of FIG. 8, the pitch of the cage attachment links 104a is about 440 mm.
[0043]
The number of links that mesh with the upper and lower sprockets at one time is 7 to 8 in the structure of FIG. 3 and 7 in the structure of FIG.
[0044]
In the structure of FIG. 3, the distance between the centers of the upper and lower sprockets 2A and 3A is about 7778 mm, and in the structure of FIG. 8, the distance between the centers of the upper and lower sprockets 2 and 3 is about 7918 mm.
[0045]
The following is understood from the above comparison. That is, in the structure of FIG. 8, the cage pitch can be adjusted only by the pitch unit of the links 104a, 104b (approximately 440 mm unit), whereas the sprockets 2A, 3A as in the structure of FIG. , 4c, it is possible to adjust the cage pitch by the pitch unit (about 148 mm unit) of the link 4c. That is, in the structure of FIG. 3, it is possible to adjust and set a finer cage pitch than in the structure of FIG. 8, while keeping the diameter of the sprocket the same as in the structure of FIG. Also, since the diameter of the sprocket can be the same as that of the conventional (existing) vertical circulation type parking device, many of the design contents of the conventional (existing) vertical circulation type parking device are newly constructed. The present invention can be used for a vertical circulation type parking device, and when the existing vertical circulation type parking device is modified to increase the cage pitch, the modification work does not become large.
[0046]
Further, as compared with the structure of FIG. 8, the number of teeth of the sprockets 2A and 3A in the structure of FIG. 3 does not decrease, and the number of links that mesh with the sprocket at one time does not decrease. Therefore, the rotation of the main chain 4A in the structure of FIG. 3 does not lack smoothness as compared with the structure of FIG.
[0047]
In addition, the length of the cage attachment link 4a in the structure of FIG. 3 is not shorter than that of the structure of FIG. 8, and therefore, the reaction force of the rollers at both ends of the cage attachment link 4a due to the load of the cage increases. There is no. Therefore, the load on the sprockets 2A and 3A and the chain guide (not shown) does not increase.
[0048]
Also, the distance between the centers of the upper and lower sprockets is shorter by about 140 mm in the structure of FIG. 3 than in the structure of FIG. Therefore, when the height position of the upper sprocket is the same in the tower, the position of the lower sprocket is about 140 mm higher in the structure of FIG. Therefore, when a cage that is higher by about 140 mm than the cage that is attached to the structure shown in FIG. 8 is attached to the structure shown in FIG. 3, it is possible to make the riding height of the vehicle the same. It is not necessary to increase the height of the cage by about 140 mm. For example, it is possible to increase the cage height by 120 mm and form a slope having a height of about 20 mm on the entry surface of the vertical circulation type parking device, thereby enabling smooth entry.
[0049]
Further, since the overall length of the main chain 4A can be adjusted in the pitch unit of the link c (unit of about 148 mm), if the height position of the upper sprocket 2A is fixed, the length unit of the half of the pitch of the link c (approximately The height position of the lower sprocket 3A can be adjusted in units of 74 mm. That is, the positioning between the vehicle mounting surface of the cage at the entry position and the entry surface of the parking device can be adjusted in units of about 74 mm.
[0050]
In the structure shown in FIG. 3, in the main chain 4A, only one cage pitch has a cage pitch of about 1760 mm such that three links 4b are interposed between the cage attachment links 4a on both sides thereof. This ensures that the height position of the car mounting surface at the entry position does not significantly change before and after the modification when considering the modification from the vertical circulation type parking device 100A having the structure as shown in FIG. This is because the overall length of the main chain 4A was adjusted. That is, even after the modification, the height position of the vehicle mounting surface of the cage at the entry position is adjusted so as not to be significantly different from the entry surface of the parking device.
[0051]
In the case where it is not necessary to consider such a situation, that is, when designing a new vertical circulation type parking apparatus instead of modifying the existing (existing) vertical circulation type parking apparatus, all of the main chain 4A May be set to a cage pitch of about 1908 mm such that three links 4b and one link 4c are interposed between the cage attachment links 4a on both sides thereof.
[0052]
FIG. 4 is a diagram showing a coupling structure of the upper sprocket 2B, the lower sprocket 3B, and the main chain 4B. In the vertical circulation type parking device P in FIG. 2, the structure for connecting the upper sprocket, the lower sprocket, and the main chain may be the structure shown in FIG. 4 instead of the structure shown in FIG.
[0053]
The structure shown in FIG. 4 has an existing vertical circulation type parking device 100A and its design as shown in FIG. 8, and is modified or modified so that a higher cage can be attached. In particular, the structure is particularly suitable.
[0054]
In the structure of FIG. 4, the same upper and lower sprockets 2A and 3A as those of FIG. 3 are used as the upper and lower sprockets 2B and 3B. That is, the number of teeth of the upper sprocket 2B and the number of teeth of the lower sprocket 3B in FIG. 4 are both 36, and their diameters are both about 1700 mm.
[0055]
The management chain 4B is configured by endlessly connecting a plurality of links 4a, 4b, 4d. The link 4a is a cage attachment link, and a cage (not shown) is suspended from a tip of the link. The links 4b and 4d have no overhang as in the cage attachment link 4a. The pitch between the link 4a and the link 4b is the same, and is about 440 mm. The link 4d has a different pitch from the links 4a and 4b. The pitch of the link 4d is about 295 mm. When these links 4a, 4b, and 4d are classified by pitch, the links 4a and 4b can be classified as first links, and the link 4d can be classified as second links.
[0056]
As understood from FIG. 4, the links 4a, 4b mesh with the upper and lower sprockets 2B, 3B at intervals of three teeth. The link 4d meshes with the upper and lower sprockets 2B, 3B at intervals of two teeth.
[0057]
Most cage pitches in the service chain are about 1916 mm, but only one cage pitch is about 1760 mm. At a cage pitch of about 1916 mm, five links 4d are interposed between the links 4a on both sides thereof. At a cage pitch of about 1760 mm, three links 4b are interposed between the links 4a on both sides thereof.
[0058]
In the structure of FIG. 4, the distance between the centers of the upper and lower sprockets 2B and 3B is about 7807 mm.
[0059]
The main chain 4B in FIG. 4 does not include a link that meshes with the sprockets 2B and 3B at one tooth interval. However, if a link such as the link c in FIG. 3 that meshes with one tooth is included, the cage pitch can be adjusted in pitch units of this link (in units of about 148 mm).
[0060]
In addition, since the overall length of the main chain 4B can be adjusted in pitch units (approximately 148 mm units) of the link c, the height position of the lower sprocket 3B can be adjusted in half length units (approximately 74 mm units). That is, the positioning between the vehicle mounting surface of the cage at the entry position and the entry surface of the parking device can be adjusted in units of about 74 mm.
[0061]
Also in the structure of FIG. 4, the number of teeth of the sprocket is not reduced as compared with the structure of FIG. 8, and the number of links that mesh with the sprocket at one time is not reduced.
[0062]
Also in the structure of FIG. 4, the length of the cage attachment link is not shorter than that of the structure of FIG.
[0063]
In addition, the distance between the centers of the upper and lower sprockets is shorter by about 111 mm in the structure of FIG. 4 than in the structure of FIG. Therefore, when the height position of the upper sprocket in the tower is the same, when a cage having a height higher than that of the cage attached to the structure of FIG. 8 by about 111 mm is attached to the structure of FIG. 4, the entry height of the vehicle is the same. can do. As described above, the height of the cage can be adjusted by forming a slope on the entry surface.
[0064]
In the structure of FIG. 4, in the main chain 4B, only one cage pitch has a cage pitch of about 1760 mm such that three links 4b are interposed between the cage attachment links 4a on both sides thereof. This ensures that the height position of the car mounting surface at the entry position does not significantly change before and after the modification when considering the modification from the vertical circulation type parking device 100A having the structure as shown in FIG. This is because the overall length of the main chain 4B was adjusted.
[0065]
In the case where it is not necessary to consider such a situation, that is, when designing a new vertical circulation parking device instead of modifying the existing (existing) vertical circulation parking device, all of the main chain 4B is required. Can be made a cage pitch of about 1916 mm such that five links 4d are interposed between the cage attachment links 4a on both sides thereof.
[0066]
FIG. 5 is a diagram showing a coupling structure of the upper sprocket 2C, the lower sprocket 3C, and the main chain 4C. In the vertical circulation type parking device P in FIG. 2, the upper sprocket, the lower sprocket, and the main chain may be joined together as shown in FIG. 5 instead of the structure shown in FIG.
[0067]
The structure shown in FIG. 5 has an existing vertical circulation type parking device 100A and its design as shown in FIG. 8, and is modified or modified so that a higher cage can be attached. In particular, the structure is particularly suitable.
[0068]
5, the upper and lower sprockets are different from the upper and lower sprockets 2A and 3A of FIG. That is, the number of teeth of both the upper sprocket 2C and the lower sprocket 3C in FIG. However, the diameter of the upper and lower sprockets 2C and 3C in FIG. 5 is the same as that of the upper and lower sprockets 2A and 3A in the structure of FIG. 3, and the diameter of each of the upper and lower sprockets 2C and 3C is about 1700 mm.
[0069]
The supervisory chain 4C is configured by endlessly connecting a plurality of links 4e, 4f, 4g. The link 4e is a cage attachment link, and a cage (not shown) is hung from the tip thereof. The links 4f and 4g have no overhang as in the cage attachment link 4e. The pitch between the link 4e and the link 4f is the same and is about 440 mm. The link 4g has a different pitch from the links 4e and 4f. The pitch of the link 4g is about 222 mm. When the links 4e, 4f, and 4g are classified by pitch, the links 4e and 4f can be classified as first links, and the link 4g can be classified as second links.
[0070]
As understood from FIG. 5, the links 4e, 4f mesh with the upper and lower sprockets 2C, 3C at intervals of two teeth. The link 4g meshes with the upper and lower sprockets 2C and 3C at intervals of one tooth.
[0071]
In the main chain 4C, the cage pitch is about 1993 mm or about 1760 mm. At a cage pitch of about 1760 mm, three links 4f are interposed between the links 4e on both sides thereof. At a cage pitch of about 1993 mm, seven links 4g are interposed between the links 4e on both sides thereof.
[0072]
In the structure of FIG. 5, the distance between the centers of the upper and lower sprockets 2C and 3C is about 7730 mm.
[0073]
When the main chain is constituted by links such as the links 4e, 4f, and 4g using the sprockets 2C and 3C having the structure shown in FIG. 5, the cage pitch is adjusted by the pitch unit (about 222 mm unit) of the link 4g. be able to.
[0074]
In addition, since the overall length of the main chain 4C can be adjusted in pitch units (approximately 222 mm units) of the link g, the height position of the lower sprocket 3C can be adjusted in half length units (approximately 111 mm units). That is, the positioning between the vehicle mounting surface of the cage at the entry position and the entry surface of the parking device can be adjusted in units of about 111 mm.
[0075]
Also in the structure of FIG. 5, the number of teeth of the sprocket does not decrease and the number of links meshing with the sprocket does not decrease as compared with the structure of FIG.
[0076]
Also in the structure of FIG. 5, the length of the cage attachment link is not shortened as compared with the structure of FIG.
[0077]
Further, the distance between the centers of the upper and lower sprockets in the structure of FIG. 5 is shorter than that of FIG. 8 by about 188 mm. Therefore, when the height position of the upper sprocket in the tower is the same, if a cage that is higher than the cage attached to the structure of FIG. 8 by about 188 mm is attached to the structure of FIG. can do. As described above, the height of the cage can be adjusted by forming a slope on the entry surface.
[0078]
In the structure shown in FIG. 5, in the main chain 4C, some cage pitches are about 1760 mm such that three links 4f are interposed between the cage attachment links 4e on both sides thereof. This ensures that the height position of the car mounting surface at the entry position does not significantly change before and after the modification when considering the modification from the vertical circulation type parking device 100A having the structure as shown in FIG. This is because the overall length of the main chain 4C was adjusted.
[0079]
In the case where it is not necessary to consider such a situation, that is, when designing a new vertical circulation type parking device instead of modifying the existing (existing) vertical circulation type parking device, all of the main chain 4C is required. Can be set to a cage pitch of about 1993 mm such that seven links 4g are interposed between the cage attachment links 4e on both sides thereof.
[0080]
FIG. 6 is a diagram showing a coupling structure of the upper sprocket 2D, the lower sprocket 3D, and the main chain 4D. In the vertical circulation type parking device P in FIG. 2, the structure for connecting the upper sprocket, the lower sprocket, and the main chain may be a structure shown in FIG. 6 instead of the structure shown in FIG.
[0081]
The structure shown in FIG. 6 has an existing vertical circulation type parking device 100A or its design as shown in FIG. 8, and is modified or modified so that a higher cage can be attached. In particular, the structure is particularly suitable.
[0082]
In the structure of FIG. 6, the upper and lower sprockets are different from the upper and lower sprockets 2A and 3A of the structure of FIG. That is, the number of teeth of both the upper sprocket 2D and the lower sprocket 3D in FIG. However, the diameter of the upper and lower sprockets 2D and 3D in FIG. 6 is the same as that of the upper and lower sprockets 2A and 3A of the structure in FIG. 3, and the diameter of each of the upper and lower sprockets 2D and 3D is about 1700 mm.
[0083]
The supervisory chain 4D is configured by connecting a plurality of links 4s, 4t, 4u endlessly. The link 4s is a cage attachment link, and a cage (not shown) is suspended from a tip of the link. The links 4t and 4u do not have an overhang as in the cage attachment link 4s. The pitch between the link 4s and the link 4t is the same, and is about 459 mm. The link 4u has a different pitch from the links 4s and 4t. The pitch of the link 4u is about 231 mm. When the links 4s, 4t, and 4u are classified by pitch, the links 4s and 4t can be classified as first links, and the link 4u can be classified as second links.
[0084]
As understood from FIG. 6, the links 4s, 4t mesh with the upper and lower sprockets 2D, 3D at intervals of two teeth. The link 4u meshes with the upper and lower sprockets 2D and 3D at intervals of one tooth.
[0085]
Of the total number of links in the supervisory chain 4D, only one is the link 4u. All other links have the same pitch.
[0086]
Most cage pitches in the service chain are about 1835 mm, but only one cage pitch is about 2526 mm. At a cage pitch of about 1835 mm, three links 4t are interposed between the links 4s on both sides thereof. At a cage pitch of about 2526 mm, four links 4t and one link 4u are interposed between the links 4s on both sides thereof.
[0087]
In the structure of FIG. 6, "23" which is the number of teeth of the upper and lower sprockets 2D and 3D is not an integral multiple of "2" which is the tooth number interval when the links 4s and 4t mesh with the upper and lower sprockets 2D and 3D. Therefore, the teeth of the sprockets 2D and 3D meshing with the link are different between the first and second rotations of the upper and lower sprockets 2D and 3D. Each tooth of the sprockets 2D and 3D can be engaged with the link only once every two rotations, so that wear is small. When the upper and lower sprockets 2D and 3D rotate a large number of times, all the teeth mesh with the link evenly.
[0088]
Here, the coupling structure of FIG. 6 and the coupling structure of FIG. 8 are compared.
[0089]
In both the structure of FIG. 6 and the structure of FIG. 8, the diameter of the upper and lower sprockets is about 1700 mm.
[0090]
In the structure of FIG. 6, most cage pitches are about 1835 mm, and in the structure of FIG. 8, all cage pitches are about 1760 mm.
[0091]
In the structure of FIG. 6, the pitch of the cage attachment links 4s is about 459 mm, and in the structure of FIG. 8, the pitch of the cage attachment links 4a is about 440 mm.
[0092]
The number of links that mesh with each of the upper and lower sprockets at one time is seven in the structure of FIG. 6 and seven in the structure of FIG.
[0093]
In the structure of FIG. 6, the distance between the centers of the upper and lower sprockets 2D and 3D is about 7795 mm, and in the structure of FIG. 8, the distance between the centers of the upper and lower sprockets 2 and 3 is about 7918 mm.
[0094]
The following is understood from the above comparison. That is, in the structure of FIG. 8, the cage pitch is about 1760 mm, whereas in the structure of FIG. 6, the cage pitch is smaller than that of FIG. It is about 1835 mm, which is slightly longer.
[0095]
Compared with the structure of FIG. 8, the number of teeth of the sprocket in the structure of FIG. 6 is not reduced, and the number of links meshing with the sprocket is almost the same. Therefore, the rotation of the main chain in the structure of FIG. 6 does not lack smoothness as compared with the structure of FIG.
[0096]
Compared with the structure of FIG. 8, the length of the cage attachment link in the structure of FIG. 6 is not shortened, so that the reaction force of the rollers at both ends of the cage attachment link due to the load of the cage does not increase. Therefore, the load on the sprockets 2D and 3D and the chain guide (not shown) does not increase.
[0097]
Further, the distance between the centers of the upper and lower sprockets is shorter by about 123 mm in the structure of FIG. 6 than in the structure of FIG. Therefore, when the height position of the upper sprocket is the same in the tower, the position of the lower sprocket is about 123 mm higher in the structure of FIG. However, it is not possible to attach a cage having a height of about 123 mm higher than the cage attached to the structure of FIG. 8 to the structure of FIG. 6 due to the cage pitch (the cage pitch is only increased by about 75 mm). Thus, for example, by attaching a cage about 70 mm higher than the cage attached to the structure of FIG. 8 to the structure of FIG. 6 and forming a slope of about 53 mm in height on the entry surface of the vertical circulation parking device, etc. You may make it possible to get in smoothly.
[0098]
In the structure of FIG. 6, in the main chain 4D, only one cage pitch is about 2526 mm such that four links 4t and one link 4u are interposed between the cage attachment links 4s on both sides thereof. Cage pitch. This ensures that the height position of the car mounting surface at the entry position does not significantly change before and after the modification when considering the modification from the vertical circulation type parking device 100A having the structure as shown in FIG. This is because the overall length of the main chain 4D was adjusted.
[0099]
In the case where it is not necessary to consider such a situation, that is, when a new vertical circulation type parking device is designed instead of a modification from the existing (existing) vertical circulation type parking device, all of the management chains 4D are required. May be a cage pitch of about 1835 mm such that three links 4t are interposed between the cage attachment links 4s on both sides thereof.
[0100]
FIG. 7 is a diagram showing a coupling structure of the upper sprocket 2E, the lower sprocket 3E, and the main chain 4E. In the vertical circulation type parking device P in FIG. 2, the structure for connecting the upper sprocket, the lower sprocket, and the main chain may be a structure shown in FIG. 7 instead of the structure shown in FIG.
[0101]
The structure shown in FIG. 7 has an existing vertical circulation type parking device 100A or its design as shown in FIG. 8, and is modified or modified so that a higher cage can be attached. In particular, the structure is particularly suitable.
[0102]
In the structure of FIG. 7, the upper and lower sprockets are different from the upper and lower sprockets 2A and 3A of FIG. That is, both the upper sprocket 2E and the lower sprocket 3E in FIG. However, the diameter of the upper and lower sprockets 2E and 3E in FIG. 7 is the same as that of the upper and lower sprockets 2A and 3A in the structure of FIG. 3, and the diameter of each of the upper and lower sprockets 2E and 3E is about 1700 mm.
[0103]
The management chain 4E is configured by endlessly connecting a plurality of links 4v and 4w. The link 4v is a cage attachment link, and a cage (not shown) is suspended from the tip of the link. The link 4w has no overhang as in the cage attachment link 4v. The pitch between the link 4v and the link 4w is the same, and is about 493 mm.
[0104]
As understood from FIG. 7, the links 4v, 4w mesh with the upper and lower sprockets 2E, 3E at intervals of three teeth.
[0105]
All the links in the management chain 4E have the same pitch.
[0106]
Most cage pitches in the main chain 4E are about 1974 mm, but only one cage pitch is about 2958 mm. In the cage pitch of about 1974 mm, three links 4w are interposed between the links 4v on both sides thereof. At a cage pitch of about 2958 mm, five links 4w are interposed between the links 4v on both sides thereof.
[0107]
In the structure of FIG. 7, "32" which is the number of teeth of the upper and lower sprockets 2E and 3E is not an integral multiple of "3" which is the tooth number interval when the links 4v and 4w mesh with the upper and lower sprockets 2E and 3E. The teeth of the sprockets 2E, 3E meshing with the links are different at the first, second, and third rotations of the upper and lower sprockets 2E, 3E. Since the teeth of the sprockets 2E and 3E can be engaged with the link only once every three rotations, wear is small. When the upper and lower sprockets 2E and 3E rotate a large number of times, all the teeth mesh with the link evenly.
[0108]
Here, the coupling structure of FIG. 7 is compared with the coupling structure of FIG.
[0109]
7 and FIG. 8, the diameter of the upper and lower sprockets is about 1700 mm.
[0110]
In the structure of FIG. 7, most cage pitches are about 1974 mm, and in the structure of FIG. 8, all cage pitches are about 1760 mm.
[0111]
In the structure of FIG. 7, the pitch of the cage attachment link 4v is about 493 mm, and in the structure of FIG. 8, the pitch of the cage attachment link 4a is about 440 mm.
[0112]
The number of links that mesh with each of the upper and lower sprockets at one time is seven in the structure of FIG. 7 and seven in the structure of FIG.
[0113]
In the structure of FIG. 7, the distance between the centers of the upper and lower sprockets 2E and 3E is about 7729 mm, and in the structure of FIG. 8, the distance between the centers of the upper and lower sprockets 2 and 3 is about 7918 mm.
[0114]
The following is understood from the above comparison. That is, in the structure of FIG. 8, the cage pitch is about 1760 mm, whereas in the structure of FIG. 7, the cage pitch is larger than that of FIG. 8 while keeping the diameter of the sprocket the same as that of FIG. It is slightly longer, about 1974 mm.
[0115]
Compared with the structure of FIG. 8, the number of teeth of the sprocket in the structure of FIG. 7 is not reduced, and the number of links that mesh with the sprocket at one time is almost the same. Therefore, the rotation of the main chain in the structure of FIG. 7 does not lack smoothness as compared with the structure of FIG.
[0116]
Compared with the structure of FIG. 8, the length of the cage attachment link in the structure of FIG. 7 is not shortened, so that the reaction force of the rollers at both ends of the cage attachment link due to the load of the cage does not increase. Therefore, the load on the sprockets 2E and 3E and the chain guide (not shown) does not increase.
[0117]
Also, the distance between the centers of the upper and lower sprockets in the structure of FIG. 7 is shorter than that of FIG. 8 by about 189 mm. Therefore, when the height position of the upper sprocket is the same in the tower, the position of the lower sprocket is about 189 mm higher in the structure of FIG. When a cage having a height of about 189 mm higher than the cage attached to the structure of FIG. 8 is attached to the structure of FIG. 7, the vehicle can reach the same height. In addition, the height of the cage can be adjusted by forming a slope on the entry surface.
[0118]
In the structure shown in FIG. 7, in the main chain 4E, only one cage pitch has a cage pitch of about 2958 mm such that five links 4w are interposed between the cage attachment links 4v on both sides thereof. This prevents the vertical position of the vehicle mounting surface of the cage at the entry position from being significantly changed before and after the modification when considering the modification from the vertical circulation type parking device 100A having the structure as shown in FIG. This is because the overall length of the main chain 4E was adjusted.
[0119]
In the case where it is not necessary to consider such a situation, that is, when designing a new vertical circulation parking device instead of modifying the existing (existing) vertical circulation parking device, all of the main chain 4E May be a cage pitch of about 1974 mm such that three links 4w are interposed between the cage attachment links 4v on both sides thereof.
