Abstract

PURPOSE: To reduce cost by arranging reduction gears between a driving motor and one lower sprocket and fixing the final-stage reduction gear on the same shaft in the sprocket while both lower sprockets are connected by a shaft. CONSTITUTION: Since a driving device 41 is formed of a driving motor 42 and a pair of reduction gear groups 431, 432, the number of components of the driving device is made half than in the case, conventional power transmission mechanisms are used to the left and the right. Since the device 41 is installed to the lower section of a building, the device 41 can be mounted at the same time as construction works up to the first joint of the building, and operating efficiency is improved while power wirings are shortened. Even when large vertical load is generated on one side of driving chains 511, 512 according to the state of the storage of automobiles, the chains 511, 512 are balanced because of the driving of lower sections, and load to an upper machine stand is lightened. Since there is a mechanical sound source in a lower section, noises to the upper floor layers of peripheral buildings are reduced. Accordingly, the number of parts can be decreased, and the execution of works is done efficiently.

The final stage reduction gears 137 and 138 are coaxially integrally attached to the upper sprockets 111 and 112 and receive power from the intermediate gears 135 and 136 while decelerating the power.

Reference numerals 141 and 142 are a pair of lower sprockets, which are axially supported in the lower part of the installation space of the multi-storied parking device and are arranged to face each other.

Reference numerals 151 and 152 are a pair of endless drive chains. One drive chain 151 is between one upper sprocket 111 and lower sprocket 141, and the other drive chain 152 is the other upper sprocket 112. And the lower sprocket 142, respectively. As shown in FIG. 10, a plurality of guide rollers 160 are attached to each of the drive chains 151 and 152, and the upper and lower sprockets 111 and 14 are installed on a preset circulation path of each of the drive chains 151 and 152.
1 and the guide rails 161 and 162 disposed between 112 and 142, respectively, to guide the vertical movement of the drive chains 151 and 152. Reference numeral 170 denotes a cage for mounting on a vehicle. As shown in FIG. 10, the support shafts 171 thereof are respectively attached to the drive chains 151 and 15 respectively.
It is suspended and fixed to the No. 2 via an attachment plate 180 and is hung. In these drive chains 151 and 152, as shown in FIGS. 11 and 12, a link plate 1502 having a bush 1501 fixed is connected between adjacent pin members, and the guide roller 160 is provided outside the bush 1501. , And an attachment plate 180 having a connecting hole 181 at the tip is attached to the guide roller 160 portion. Therefore, each cage 170 is attached by connecting the support shaft 171 to the connection hole 181 of the attachment plate 180.

The vertical circulation type three-dimensional parking apparatus is generally provided with such a structure, and by operating the drive motor 121 of the upper drive unit 120 thereof, both machine stands 101, 10 are installed.

[0006]

However, in the above-mentioned conventional vertical circulation type three-dimensional parking apparatus, since the upper sprocket is on the driving side, there are the following problems. (1) Due to the orbital movement of the drive chain on the upper sprocket, each cage passes between the pair of upper sprockets, so that the upper sprockets cannot be directly connected to each other by the power transmission shaft. A total of two sets of power transmission mechanisms using a large number of gears are required, one set for each upper sprocket. In addition, the guide roller attached to the cage connecting part to the drive chain projects outward in the width direction of the drive chain, and the orbit of the drive chain is close to the final stage reduction gear with only a slight gap left. If you set the diameter of the final stage reduction gear to a large value, this reduction gear will interfere with the guide roller,
The power transmission mechanism cannot be configured. For this reason, in the power transmission mechanism, the reduction gear at the final stage must have the diameter dimension suppressed to some extent. Therefore, as described above, the intermediate gears (reference numerals 135 and 136 in FIG. 10) only for power transmission are required. It has become. Therefore, the structure of the driving device is complicated and the cost is high. (2) When a large vertical load is generated on one side (one side on one side of the upper and lower sprockets) of each drive chain depending on the storage state such as the storage direction of the vehicle, the overturning moment to the upper machine base is large, so the machine It is necessary to use a large beam with high strength for the base, which is also a major factor in increasing costs. (3) Due to the installation work, the independent steel tower is first divided into a plurality of nodes and assembled in order from the bottom, and after the assembly is completed, the drive device is installed on the upper part using the hoist, so the structure of the drive device is complicated. Due to its large weight, a great number of man-hours are required for construction. Further, since the distance of the power wiring is long, the material is increased, and the wiring work requires a great number of man-hours. (4) Since the drive device is installed on the upper part, the mechanical noise is loud on the upper part. When this multi-storey parking device is constructed adjacent to the area where high-rise buildings are lined up, the surrounding buildings are generally required to be quiet. It has the drawback that it harms the environment of the upper floors and impairs its habitability.

The present invention solves such a conventional problem, eliminates the complicated structure of the driving device, reduces the number of parts to reduce the cost, and reduces the man-hours and the work in construction. It is an object of the present invention to provide a vertical circulation type multi-level parking device that can improve efficiency and, on the other hand, can maintain a favorable living environment for an adjacent peripheral building in operation.

[0008]

In order to achieve the above object, the invention according to claim 1 is such that a drive device has a drive motor and a reduction gear group constituting a power transmission mechanism thereof, and the reduction gear group Is disposed between the drive motor and one of the lower sprockets, and the final stage reduction gear is coaxially provided integrally with the one of the lower sprockets.
Both lower sprockets are integrally connected via a connecting shaft.

According to a second aspect of the present invention, in the above structure, the guide roller is arranged between the link plates forming the drive chain so that the guide roller does not interfere with the final reduction gear. The diameter of the reduction gear at the final stage is set to be larger than the diameter of the lower sprocket, and the intermediate gear used only for power transmission is eliminated.

According to a third aspect of the present invention, in each of the above-described configurations, the lower sprocket is pivotally supported on the support frame via the self-aligning bearings, and one set of reduction gear groups is arranged on one side. The self-aligning bearing of the lower sprocket is arranged in a direction perpendicular to the meshing position between the final reduction gear and the preceding reduction gear.

According to a fourth aspect of the present invention, in each of the above-mentioned configurations, each upper sprocket is axially supported by a cantilever inside the supporting portion arranged at the upper part of the building.

[0012]

Therefore, according to the present invention, with the structure of claim 1, the power of the drive motor can be transmitted by one set of reduction gears to drive both lower sprockets to rotate, and the drive device can be driven by a large number of parts. It can be realized with a small and simple device configuration.

Further, since the driving device has such a simple device configuration and is arranged at the bottom, construction work, construction of various frames, and installation of the driving device can be performed at the same time. It is possible to reduce man-hours and improve work efficiency. In addition, since the distance of the power wiring is shortened, the materials are reduced and the man-hour required for the wiring work can be reduced. In addition, due to its operation, it is possible to maintain a favorable living environment of the upper floor with respect to the adjacent surrounding buildings.

According to the second aspect of the invention, the number of parts in the power transmission mechanism can be reduced, and the drive device can be realized with a simpler device configuration.

According to the third aspect of the present invention, due to the difference in the loads of the drive chains or the elongation due to wear, the reduction gear of the final stage integrated with one lower sprocket and the reduction gear of the previous stage for transmitting power to the reduction gear. If a slight deviation occurs in the meshing, the deviation is absorbed by the self-aligning bearing, and if a large deviation exceeding a certain limit occurs, the reduction gear at the final stage is displaced and moved by the deviation. Can be adjusted.

Further, according to the structure of claim 4, the number of parts can be reduced by the amount by which both upper sprockets are cantilevered, and the space between both sprockets is reduced by the excess space generated inside each upper sprocket. This makes it possible to reduce the size of the entire multi-level parking device.

And a final stage reduction large gear 432 that is coaxially integrally attached to one of the lower sprockets 322 and meshes with the reduction small gear 431. Here, the large reduction gear 43
The diameter of 2 is set larger than the diameter of the lower sprocket 322, so that the reduction small gear 431 can directly mesh with the gear. Further, the self-aligning bearing 33 of the lower sprocket 322 is arranged in a direction perpendicular to the meshing position between the large reduction gear 432 and the preceding reduction small gear 431.

Reference numeral 34 denotes a connecting shaft, and the connecting shaft 34 serves as a pair of lower sprockets 321 and 322.

Reference numeral 53 is a cage for mounting on a vehicle, and its supporting shaft 531 is suspended and connected by bridging the drive chains 511 and 512 via the attachment plate 54.

As shown in FIGS. 7 and 8, in the drive chains 511 and 512, the guide roller 52 forms the link plate 51 that constitutes the drive chains 511 and 512.
It is mounted on the connecting pin 514 between the No. 3 and No. 3 and eliminates the conventional outward protrusion and eliminates the interference of the guide roller 52 with the large reduction gear 432 at the final stage. Therefore, in the power transmission mechanism 43 described above, the diameter of the large reduction gear 432 can be set larger than that of the lower sprocket 322. And these drive chains 511,
At the mounting portion of the guide roller 52 of 512, the attachment plate 54 is mounted from the outer side in the width direction of the drive chains 511, 512. A holder portion 55 is provided at the tip of the attachment plate 54, and the cage 53 is attached by connecting the support shaft 531 of the cage 53 to the holder portion 55 as shown in FIG.

In this way, the lower sprocket 321,

Reference numeral 35 is a tensioner spring, which is interposed between the support frames 311 and 312 and the lower fixed frame 36 to absorb the expansion and contraction of the drive chains 511 and 512.

Next, the operation of the vertical circulation type multi-level parking device will be described with reference to FIGS. 1, 3 and 5. The output of the drive motor 42 of the lower drive device 41 is transmitted from the drive pinion 422 to the drive gear 424,
The shaft 423 is rotated. As a result, the reduction small gear 4

That is, the lower sprockets 321 and 322 are rotationally driven by the connecting shaft 34, and the drive chains 511 and 512 are circularly moved between the upper and lower sprockets 231, 321, 232 and 322 to circulate the cages 53 in the vertical direction. It

As described above, according to the above embodiment, the drive device 41 is configured with the lower sprockets 321 and 322 as the drive side.
Is composed of the drive motor 42 and a set of reduction gear groups 431 and 432 that form the power transmission mechanism 43 thereof,
Compared with using two sets of power transmission mechanism as in the past,
The entire drive device 41 can be realized with a simple device configuration in which the number of constituent parts is reduced by half.

In addition, since the drive device 41 has a simple device configuration and is set at the lower part, the independent tower is divided into a plurality of sections, here three sections, and assembled in order from the bottom due to its construction. In the process, it is possible to assemble various frames and install the drive unit 41 at the same time as the construction work up to the first section, and significantly reduce the man-hours.
The work efficiency can be improved and the entire construction period can be significantly shortened. Further, since the distance of the power wiring is shortened, the materials are reduced, the man-hour required for the wiring work can be reduced, which is advantageous in terms of cost and construction. Since the drive chains 511 and 512 are moved and stopped by the lower drive, a large vertical load is generated on one side of the drive chains 511 and 512 (one side of the upper and lower sprockets as a boundary) depending on the housing state such as the storing direction of the vehicle. Even if
The balance of each drive chain 511, 512 is maintained, and thus the load on the upper machine stand is reduced, so that a stand supporting beam having a small strength and simple structure can be used for the upper machine base 21. The cost can be reduced.

In addition, since the source of mechanical noise is at the bottom during operation, it is possible to maintain the quietness required for the upper floors of the neighboring buildings and maintain its habitability. it can.

Further, since the diameter of the large reduction gear 432 integral with the lower sprocket 322 is set to be larger than the diameter of the lower sprocket 322, the conventional intermediate gear used only for transmitting power is eliminated. The drive device 41 can be realized with a simpler device configuration.

Further, each lower sprocket 321, 322
Support frame 31 by self-aligning bearings 33
As shown in FIG. 6, the self-aligning bearing 33 is axially supported by the first and third 312th gears 431 and 432. Since it is arranged in the direction perpendicular to the meshing position with the preceding reduction gear 431, the final reduction gear 432 at the final stage is caused by the difference in load between the pair of drive chains 511 and 512 or elongation due to wear. When a slight deviation occurs in the meshing between the gear and the reduction small gear 431 in the preceding stage, the deviation is absorbed by the self-aligning bearing 33, and if a large deviation exceeding a certain limit occurs, the final stage The reduction gear 432 can be displaced and moved by the amount of the shift to make the adjustment.

Further, since the tensioner spring 35 is interposed between the support frames 311 and 312 of the lower sprockets 321, 322 and the lower fixed frame 36, the drive chain 511 according to the increase or decrease in the number of parked cars in the plurality of cages 53. Since the expansion and contraction of 512 is absorbed, a stable circulation operation of each cage 53 can be obtained.

Further, the upper sprockets 231, 232
The machine stands 221 and 22 placed at the top of the building
Since it is cantilevered on the inside with respect to 2, the number of parts can be reduced by the amount of cantilevering both upper sprockets 231, 232, and at the inside of each upper sprockets 231, 232. The space between the two sprockets 231 and 232 can be reduced by the amount of the generated excess space, and the entire multilevel parking apparatus can be downsized.

[0034]

Therefore, according to the present invention, claim 1
With this configuration, the power of the drive motor is transmitted by a set of reduction gear groups to drive both lower sprockets to rotate, so that the drive device can be realized with a simple device configuration with a small number of parts, Low cost can be achieved.

Since the vehicle is driven in the lower direction, even if a large vertical load is generated on one side (one side on one side of the upper and lower sprockets) of each drive chain depending on the housing state such as the storage direction of the vehicle, each drive chain is driven. The balance of the chain can be maintained, the load on the upper machine stand can be reduced, and the stand support beam of small strength and simple member structure can be used for the upper machine base. And by setting it at the bottom, it is possible to assemble various members and install the drive unit at the same time as construction work and construction work, so it is possible to reduce the number of man-hours and improve work efficiency, and in terms of power wiring, Since the distance is shortened, the materials are reduced, the man-hour required for the wiring work can be reduced, and the cost can be further reduced as a whole. That. In addition, due to its operation, the mechanical noise is at the bottom, so that it is possible to maintain a favorable living environment of the upper floors with respect to the adjacent peripheral buildings.

Further, according to the structure of claim 2, the number of parts in the power transmission mechanism can be reduced, and the drive device can be realized with a simpler device structure, and the low cost can be promoted.

According to the third aspect of the invention, when the drive chain extends, a slight deviation occurs in the engagement between the final reduction gear and the preceding reduction gear that transmits power to the final reduction gear. It can be absorbed by the self-aligning bearing, and when a large deviation exceeding a certain limit occurs,
The adjustment can be performed by displacing the reduction gear at the final stage by the amount of the shift.

According to the structure of claim 4, the number of parts is reduced by cantilevering both upper sprockets, which can promote cost reduction, and the excess space generated inside each upper sprocket. Only by reducing the space between both sprockets, it is possible to reduce the size of the three-dimensional parking apparatus as a whole.
