Description

The present invention relates to a vertical circulation parking system, and more particularly, to a wire-driven vertical circulation parking system.

A vertical circulation parking system, also called a tower parking system, is a mechanical parking system in which a number of cages on which vehicles (e.g., passenger cars) are placed are rotated vertically like a merry-go-round (or Ferris wheel) to allow vehicles to enter and leave the parking lot. be. In this vertical circulation type parking system, a main chain is endlessly stretched between upper and lower sprockets attached to a steel frame that serves as a frame of the parking system, and a plurality of cages attached to this main chain are vertically rotated.

The entry/exit entrance of the vertical circulation parking system is usually provided on the first floor, and the upper sprocket is rotated by a motor to raise and lower the master chain that is stretched between the upper and lower sprockets to lower the cage to the first floor. Vehicles can enter and leave the parking lot.

The vertical circulation parking system described above is disclosed, for example, in Patent Document 1.
Patent Literature 1 discloses a method for modifying an existing vertical circulation parking system for high-roof vehicles and heavy-duty vehicles. In this retrofitting method, the existing main chain is replaced with another main chain having attachments spaced wider than the existing adjacent cage attachments. Furthermore, a cage for high-roof vehicles is attached to the attachment.

Japanese Patent Application Laid-Open No. 2001-193301

The conventional vertical circulation parking system described above has the following problems.
(1) It is not possible to freely change the spacing of cage attachments.
For example, in an existing vertical circulation parking system for storing standard-sized cars with a vehicle height of 1550 mm, if the chain pitch is 455 mm, cage attachments are attached at intervals of 1820 mm every four pitches.
For example, in order to store a high-roof vehicle (HR vehicle) with a vehicle height of 2050 mm, it is necessary to change the attachments to 2275 mm spaced every 5 pitches.
Therefore, conventionally, it is necessary to replace the chain with a main chain having a different attachment interval as in Patent Document 1, resulting in a high remodeling cost and a long remodeling period.
When modifying an existing vertical circulation parking system for storing standard-sized cars so that standard-sized cars and HR cars are mixed, similarly, it is necessary to replace the main chains with different attachment intervals.
(2) Noise during driving due to tooth contact between the sprocket of the drive unit and the main chain is large.
In the vertical circulation type parking system, a large tension force acts on the main chain to suspend a large number of vehicles. As a result, when the sprocket of the drive unit rotates the main chain, a large tooth contact noise is generated during rotation, which may annoy nearby residents.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above problems. That is, an object of the present invention is to provide a vertical circulation parking system in which the spacing between cage attachments can be freely changed without replacing the main member corresponding to the main chain, and noise during driving can be reduced. It is in.

According to the present invention, front and rear upper and lower pulleys that are attached to the upper and lower parts of the device frame and are rotatable about a horizontal axis;
front and rear master wires endlessly stretched between the upper pulley and the lower pulley;
a pulley driving device that rotationally drives the upper pulley;
a plurality of attachments detachably fixed to the main wire;
a plurality of cages suspended from the front and rear attachments,
A vertical circulation parking system is provided in which a plurality of cages on which vehicles are placed are vertically rotated and the vehicles are moved into and out of the cages at the lowest end.

According to the configuration of the present invention, conventional sprockets and main chains are eliminated, and a plurality of cages on which vehicles are mounted are rotated vertically by pulleys and main wires. The resulting driving noise can be reduced.

In addition, since a plurality of attachments are detachably fixed to the main wire, the intervals between cage attachments can be freely changed without replacing the main member (main wire) corresponding to the conventional main chain.
As a result, it is possible to change the vehicle to be stored (for example, from an ordinary car to an HR car) or to mix an ordinary car and an HR car in a free combination without exchanging the main wire.

The arc guides 35 are arc-shaped guide grooves that guide the guide rollers 33 at the upper and lower ends of the vertical circulation parking device 100, and guide the cage 30 rotating at the upper and lower ends so as not to tilt. .

FIG. 3 is an explanatory diagram of the attachment 18. As shown in FIG. In this figure, (A) is a view taken along line AA of FIG. 2, (B) is an enlarged view of portion B of (A), and (C) is a view taken along line CC of (B).
3B and 3C, the attachment 18 has an attachment body 19 and a fastener 20. As shown in FIG.

The attachment main body 19 consists of a pair of gripping portion 19a and hanging portion 19b.
The pair of gripping portions 19a are positioned at a constant interval L (“gripping interval L”) in the length direction of the main wire 14 . Each gripping portion 19a detachably grips the main wire 14 .
The suspending portion 19b is positioned outward in the width direction of the apparatus from the pair of gripping portions 19a, and suspends the cage suspending shaft 32 of the cage 30. As shown in FIG.
It is preferable that the gripping portion 19a and the hanging portion 19b are integral parts that are firmly connected.

In this example, the gripping portion 19a has a pair of gripping surfaces 19c facing each other across the main wire 14 in the front-rear direction and capable of continuously moving the gripping portion 19a in the longitudinal direction of the main wire 14. As shown in FIG. Also, the pair of gripping surfaces 19c communicate with slit grooves 19d extending in the width direction in FIG. 3(B).
With this configuration, the pair of gripping surfaces 19c of the gripping portion 19a can be moved in the front-rear direction within an elastic range.
Preferably, the gripping surface 19c is provided with a groove extending in the width direction of the main wire 14 so that the gripping surface 19c does not slip in the length direction of the main wire 14. As shown in FIG.

The fastener 20 removably secures the gripping portion 19a to the main wire 14 .
The fastener 20 is, for example, a bolt and a nut, and holds a pair of gripping surfaces 19c close to each other to fix the gripping portion 19a to the main wire 14 so that the gripping surfaces 19c do not slip in the longitudinal direction of the main wire 14. .

In FIG. 3, the attachment 18 also has a pair of guide rollers 22 . The pair of guide rollers 22 are fixed in the vicinity of the pair of gripping portions 19a, respectively, and freely rotate about a horizontal axis in the front-rear direction.
The vertical circulation parking system 100 further includes a linear guide 24 . A linear guide 24 is fixed to the apparatus frame and guides the vertical movement of the pair of guide rollers 22 .
In this example, "near" is a position close to the main wire 14 of the grip portion 19a. Also, in this example, the fastener 20 and the linear guide 24 are provided at the same position when viewed from the front in FIG. 3(C).

4 is a view taken along line BB in FIG. 2. FIG.
In this figure, the pulley drive 16 has a pair of drive units 16A and a synchronization controller 16B.
A pair of drive units 16A are each composed of an electric motor, a speed reducer, and a gear train, and rotate the front and rear upper pulleys 10 independently. The motor is preferably continuously speed controllable, for example by inverter control.
The synchronization control device 16B synchronizes the pair of drive units 16A based on the positions of the front and rear attachments 18. As shown in FIG.

With this configuration, even if a slip occurs between the upper pulley 10 and the main wire 14 and the positions of the front and rear attachments 18 are shifted, the positions of the front and rear attachments 18 are corrected by controlling the speed of the pair of drive units 16A. can be synchronized in a short time.

FIG. 5 is an enlarged bottom view of FIG.
In this figure, the vertical circulation parking system 100 further comprises a level adjustment device 40 . The position of the level adjusting device 40 can be arbitrarily set as long as it can abut on a part of the main wire 14 extending vertically.

The level adjusting device 40 abuts on a portion of the vertically extending main wire 14 and moves the portion of the main wire 14 in the width direction to change the height of the cage 30 positioned at the lowest end. .
It should be noted that the level adjusting device 40 should be retracted while the cage 30 is being raised and lowered, and should be activated after the cage 30 is stopped.

In this example, the level adjusting device 40 comprises a roller 42 that abuts on a portion of the vertically extending main wire 14 and an actuator 44 that horizontally moves the roller 42 .

It is preferable to provide one level adjusting device 40 for each of the front and rear main wires 14 and the left and right main wires 14 (four in total). It should be noted that only one unit (a total of two units) may be provided for each of the main duty wires 14 on the front side.
Also, the direction of horizontal movement of the roller 42 is inward in this example, but may be outward.

For example, due to elongation of the main wire 14 or the like, the vehicle support surface of the cage 30 may be positioned slightly below the entry/exit height at the lowermost end. In this case, the level adjusting device 40 can raise the height of the cage 30 located at the lowest end to position the supporting surface of the vehicle at the entry/exit height.

According to the above-described embodiment of the present invention, the conventional sprocket and main chain are eliminated, and the plurality of cages 30 are rotated vertically by the pulleys 10 and 12 and the main wire 14. Therefore, the tooth contact between the sprocket and the main chain is reduced. Driving noise caused by sound can be reduced.

In addition, since the plurality of attachments 18 are detachably fixed to the main wire 14, the interval P (attachment interval) between the cage attachments 18 can be adjusted without replacing the main member (main wire 14) corresponding to the conventional main chain. P) can be freely changed.
As a result, it is possible to change the vehicle to be stored (for example, from an ordinary car to an HR car) or to mix an ordinary car and an HR car in a free combination without exchanging the main wire.

Furthermore, even if the positions of the front and rear attachments 18 are displaced due to slippage between the upper pulley 10 and the main wire 14, the synchronization control device 16B controls the speed of the pair of drive units 16A to adjust the positions of the front and rear attachments 18. It can be modified and synchronized in a short time.

Further, when the vehicle support surface of the cage 30 at the lowest end is positioned slightly below the entry/exit height, the level adjustment device 40 raises the height of the cage 30 located at the lowest end to allow the vehicle support surface to enter. Can be positioned at delivery height.

It goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications can be made without departing from the gist of the present invention.
