[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gondola type multi-level parking apparatus having a simplified gondola driving mechanism.

[0002]

2. Description of the Related Art As a three-dimensional parking system for parking a large number of vehicles, large gears are provided at the upper and lower portions of a parking tower, and endless chains are wound around the upper and lower gears so that the gondola of the vehicle can be vertically circulated. There is something I did. In such a three-dimensional parking apparatus, two sets of endless chains are suspended along the front and rear walls of the parking tower. A plurality of sets of gondola suspension bearings are provided at regular intervals along the endless chain, and a pair of front and rear suspension bearings rotatably suspends the suspension shaft. A gate-shaped pallet frame is provided on each suspension shaft, and a plate-shaped pallet for mounting wheels of a vehicle is mounted on the bottom of the pallet frame.

In order to load or unload a vehicle with the above-structured parking apparatus, a large gear is rotated in a certain direction from a drive source and a specific gondola is moved to a lower portion of a parking tower through an endless chain.

[0004]

In such a conventional three-dimensional parking apparatus, since a large number of gondola are held on the suspension shaft via endless chains, gravity is applied to the endless chains in proportion to the number of stored cars. . In addition, when the number of stored cars is increased, a large number of gondola must be suspended in the vertical direction, which increases the distance between the upper and lower large gears. In this case, due to the bending of the endless chain in the vertical portion, the gondola easily vibrates in the horizontal direction. For this reason, a guide rail for vibration prevention has to be provided in the vertical direction of the parking tower. Further, since the large gear is provided above the parking tower, the ceiling of the parking tower must be high.

The present invention has been made in view of the above-mentioned conventional problems, and it is necessary to prevent the gondola from vibrating in the horizontal direction during suspension, and to make the height of the parking tower as low as possible in comparison with the number of gondola. It is a technical subject to do so and to simplify the gondola drive mechanism.

[0006]

According to a first aspect of the present invention, a plurality of gondola for mounting a vehicle are provided, and each gondola is vertically circulated through a gondola drive mechanism in a frame to store a plurality of vehicles. In the gondola-type multi-level parking device, the gondola drive mechanism is connected to a drive motor, which is a circulation drive source of the gondola, and connected to the drive motor via a power transmission mechanism to rotate. A plurality of drive chains supported between a plurality of supported drive sprockets and upper and lower drive sprockets and vertically circulated by the rotation of the drive sprockets, and provided upright between the vertical circulation parts of the two drive chains. A pair of rectangular holding plates with four corners formed in an arc shape, and a guide chain that is endlessly wound and fixed along the outer peripheral edge of the holding plate and has the same pitch as the drive chain. When the drive chain is engaged, the traveling sprocket that moves along the guide chain and the two shafts of the traveling sprocket that move in the same direction and height are fitted into the central shaft holes to suspend the gondola and the gondola suspension shaft. Is rotatably supported by
And a connecting member connected to a gondola suspension shaft of each adjacent gondola.

In the invention of claim 2 of the present application, the gondola drive mechanism is provided in parallel with the first guide roller rotatably fitted to both ends of the gondola suspension shaft and along the lower edge of the holding plate. , And a first guide rail serving as a rotation path surface of the first guide roller.

In the invention of claim 3 of the present application, the gondola driving mechanism is provided in the lower part of the gondola and is parallel to the second guide roller having a rotation axis perpendicular to the conveying direction of the gondola and the holding plate. A second guide rail, which is provided and serves as a rotation path surface of the second guide roller when the gondola reaches the uppermost circulation position.

According to a fourth aspect of the present invention, the gondola drive mechanism is provided in the vertical circulation portion of the drive sprocket, and is provided with a first guide plate whose end surface abuts on the roller of the drive chain. It is something.

According to a fifth aspect of the present invention, there is provided a frame including a plurality of sets of pillars erected on the floor surface and a plurality of beams connected between the pillars, and the gondola drive mechanism is mounted on the floor surface by the frame. It is characterized in that it is held at a constant height.

[0011]

According to the invention of claim 1 of the present application having such a feature, when the drive motor rotates, the plurality of drive sprockets respectively pivotally supported by the frame rotate. The drive chain is stretched between the upper and lower drive sprockets and vertically circulates. The traveling sprockets fitted into both ends of the gondola suspension shaft mesh with the guide chains on the outer peripheral edge of the holding plate, and move by circulation of the drive chain.
Then, the gondola suspended on the gondola suspension shaft circulates along the guide chain. Further, since the respective gondolas are connected by the connecting member, the gondola whose traveling sprocket is not meshed with the drive chain is also conveyed at the same time. By vertically circulating the gondola in this way, the gondola drive mechanism is simplified, and commercially available mechanical parts can be used.

According to the second aspect of the present invention, when the gondola reaches the bottom of the circulation, the first guide roller is held by the first guide rail, so that the traveling sprocket meshes with the drive chain. Even without it, the gondola will move horizontally along the floor.

According to the invention of claim 3 of the present application, the second guide roller is guided by the second guide rail when the gondola reaches the circulation uppermost portion. Claim 4 of the present application
According to the invention, when the gondola circulates vertically along the drive chain, even if the drive chain receives an outward pressing force by the traveling sprocket, the position is held by the first guide plate. Therefore, the friction of the drive chain is reduced, and the drive sprocket is less likely to come off the drive chain.

The rollers are fixed so as to abut on a guide plate 9 provided along the outer peripheral edges of a and 6b. The guide plate 9 is thinner than the gap between the link plates of the guide chain 7, and is made of vinyl chloride resin having improved wear resistance.

Next, as shown in FIGS. 1 and 2, the drive sprockets 10a to 10h are rotatably attached to the shafts supported by the beams 5, respectively. Front lower drive sprocket 1
0a is the right end of the beam 5a, and the drive sprocket 1 at the upper front is

The drive sprocket 10 is a drive chain 11
It is a sprocket that meshes with and conveys a gondola described below upward or downward. Drive sprockets 10a, 10b
The drive chain 11a is interposed between the drive sprockets 10 and
A drive chain 11b is stretched between c and 10d. A drive chain 11c is stretched between the drive sprockets 10e and 10f, and a drive chain 11d is stretched between the drive sprockets 10g and 10h. The drive chains 11a to 11d are roller chains having the same shape as the guide chain 7, and a traveling sprocket 12 is provided between the drive chains 11a to 11d and the guide chain 7 as shown in the figure.

The traveling sprocket 12 has the same tooth shape as the drive sprocket 10 except that the number of teeth is different, and the traveling sprocket 12 is arranged in the number corresponding to the number of gondola of the gondola type parking system. For example, assuming that the number of gondola is eight, eight sets of traveling sprockets 12 are arranged at equal intervals along the outer peripheral portions of the guide chain holding plates 6a and 6b. The traveling sprocket 12 functions as a planetary gear that is guided by the guide chain 7 and moves in a substantially elliptical shape when the drive chain 11 rotates.

Next, as shown in FIGS. 1 and 2, a gondola suspension shaft 13 is rotatably mounted between the front and rear traveling sprockets 12 via, for example, ball bearings. The gondola suspension shaft 13 suspends a pallet frame (not shown) and is made of a rod-shaped or pipe-shaped steel material.

Two connecting bearings 14 are provided on each of the gondola suspension shafts 13 adjacent to the front and rear traveling sprockets 12. There are four connecting bearings 14 provided on one gondola suspension shaft 13. For example, as shown in FIG. 2, the connecting bearings 14a and 14b at the front are respectively connected to the connecting chain 1.
5a and 15b are connected. Similarly, the rear coupling bearing 1
4c and 14d connect the connecting chains 15c and 15d, respectively. The connection bearings 14 having such a structure are similarly provided on the other seven gondola suspension shafts 13, and the eight gondolas are connected to each other via the connection chains 15, respectively.

Next, as shown in FIGS. 1 and 2, guide rails 16a and 16b are provided in parallel along the lower side surfaces of the guide chain holding plates 6a and 6b, respectively. The guide rail 16 is a belt-shaped metal plate bent in a U shape so as to be parallel to the guide chain 7. The left and right ends of the guide rails 16a and 16b are cut at a portion close to the drive chain 11, and the gondola traveling sprocket 1 located at the lowermost surface is cut.
2 facilitates disengagement and engagement with the drive chain 11.

Next, as shown in FIGS. 1 and 2, a pair of front and rear drive sprockets 10 located at the upper part of the parking tower are connected by a drive shaft 17. That is, the right drive shaft 17a is connected between the drive sprockets 10b and 10f, and the left drive shaft 17b is connected between the drive sprockets 10d and 10h. When the rear drive sprockets 10f and 10h rotate, the rotational torque is transmitted to the front sprockets 10b and 10d via the drive shafts 17a and 17b.

As shown in FIG. 2, the drive shafts 17a, 1
Power transmission gears 18a and 18b are attached to the rear of 7b. A drive gear 19 is attached to the lower part of the rear beam 5d via a drive motor and a speed reduction mechanism (not shown). The drive gear 19 and the power transmission gears 18a and 18b
The power transmission chain 20 is stretched between them, and the rotational torque of the drive motor is transmitted to the drive chains 11a to 11d.

Next, the gondola 21 will be described with reference to FIGS. 3, 4 and 5. FIG. 3 shows eight gondola 21a-2.
FIG. 4 is a front view of a gondola drive mechanism 1 to which 1h is attached, and FIG. 4 is a side view showing a configuration of a gondola 21. As shown in FIGS. 3 and 4, a pallet frame 22 is suspended on each gondola suspension shaft 13. The pallet frame 22 is formed by connecting a suspension portion 23 in which a steel pipe is bent in an inverted U shape and a rectangular floor frame 24, and has a function of holding a pallet on which a vehicle is placed.

As shown in FIG. 4, the gondola suspension shaft 1
3 includes a first guide roller 25, a traveling sprocket 12, and two coupling bearings 14 inward from the left and right ends thereof.
Is rotatably inserted. Further, a gondola bearing 26 is mounted inside the coupling bearing 14. The suspension portion 23 is suspended via a universal bearing provided below the gondola bearing 26, and the floor frame 24 is connected thereto. The floor frame 24 is for placing a pallet, and two second guide rollers 27 are horizontally provided behind the floor frame 24.

FIG. 5 is a front view showing the relationship between the guide roller 27 of the gondola 21 located at the uppermost portion shown in FIG. 3 and the second guide rail 30 for guiding the guide roller 27. Guide roller 27
Different from the guide roller 25, when the gondola 21 is located at the top of the parking tower, it is guided by the guide rail 30 to prevent the gondola 21 from rotating. The guide rail 30 is a rail having left and right ends curved downward, and is fixed to the reinforcing frame 8 via stays. Further, the guide roller 27 functions to prevent the vibration of the gondola 21 that occurs when the vehicle enters and leaves the floor 3 by coming into contact with the floor surface 3 when the gondola 21 is located on the lowermost surface of the parking tower.

FIG. 6 is a partial sectional view showing the structure of each member attached to the end of the gondola suspension shaft 13. As shown in this figure, a guide roller 25 is rotatably provided at the end of the gondola suspension shaft 13. The guide roller 25 is a member that rolls on the guide rail 16 shown in FIG. 2 when the gondola 21 comes to the bottom of the parking tower, and holds the total weight of the gondola 21.

Next, the connecting chain 15 connects the other gondola adjacent to its own gondola 21. The connecting bearing 14 and the connecting chain 15 are provided for the traveling sprocket 12 when a specific gondola 21 is at the top or bottom of the parking tower.
Since it is disengaged from the drive chain 11, the moving force of the two adjacent gondolas is used to convey its own gondola. Further, the connecting chain 15 has a function of preventing the gondola 21 from dropping downward even if the traveling sprocket 12 of the vertically moving gondola 21 is detached from the drive chain 11.

FIG. 7 is a front view showing an engaged state of the drive chain 11 and the guide chain 7 which meshes with the traveling sprocket 12, and FIG. 8 is a drive chain 11 and the guide plate 9 in the YY line portion shown in FIG. FIG. 6 is a cross-sectional view showing the engaged state of FIG. As shown in FIG. 7, the guide chain 7 is fixed along the outer peripheral end surface of the guide chain holding plate 6, and the split pin 28
To be connected endlessly. As shown in FIG. 8, the guide plate 9 is the link plate 3 of the guide chain 6.
The guide chain 7 is inserted between the guide chain 7 and the roller 32.
Is held so as not to retreat to the right in FIG.
Similarly to the guide plate 9, the second guide plate 29 is inserted between the link plates of the drive chain 11 and comes into contact with the rollers to form a sliding surface of the drive chain 11. The material of the guide plate 29 is excellent in wear resistance and has a low sliding friction coefficient, and is made of, for example, vinyl chloride resin.

The operation of the gondola type three-dimensional parking apparatus of the present embodiment constructed as above will be described. First, as shown in FIG. 3, it is assumed that an empty car gondola 21a is located at the bottom of the parking tower. Next, the vehicle is driven in the direction of arrow X in FIG. 1 to move it onto the pallet of the gondola 21a. In this case, the weight of the gondola 21a including the vehicle is equal to that of the guide roller 2
It is supported by a guide rail 16 via 5. In addition, when the guide roller 27 shown in FIG.
a does not rotate around the gondola suspension shaft 13 when the vehicle is stored.

Next, the gondola 21a on which the vehicle is mounted is shown in FIG.
Consider the case of moving from the position indicated by P1 to the position indicated by P3. When the drive gear 19 shown in FIG. 2 is rotated by the drive motor in the counterclockwise direction (ccw) as viewed from the direction of arrow D, the power transmission chain 20 also rotates in the ccw direction, and the power transmission gears 18a and 18b also rotate in the same direction. To do. This rotational torque is transmitted through the drive shafts 17a and 17b to the drive sprockets 10f and 10b and the drive sprockets 10h and 1b.
It is transmitted to 0d. Therefore, all drive chains 11a
11d rotate in the ccw direction when viewed from the front.

At this time, the gondola 2 located at P3 in FIG.
1c tries to move upward. Similarly, the gondola 21g located at P7 tries to move downward. Assuming that the traveling sprocket 12 of FIG. 7 is the gondola 21c of FIG. 3, the left tooth of the traveling sprocket 12 in FIG. 7 is lifted upward as indicated by arrow H. Therefore, the traveling sprocket 12 rotates clockwise (cw) and is guided by the guide chain 7 to move upward. Drive chain 11
Since the guide plate 29 presses the roller of the drive chain 11b during the rotation of b, the drive chain 11b is always meshed with the travel sprocket 12 without being pressed by the travel sprocket 12 and retreating to the left side.

The drive chain 11d shown in FIG. 2 also rotates in the ccw direction like the drive chain 11b, and the gondola 21c
Moves upwards. When the gondola 21c rises in this manner, the gondola 21b is lifted upward by the connecting chain 15 stretched around the connecting bearings 14 of the gondola 21c and 21b. Further, the connecting chain 15 stretched between the gondola 21b and 21a also pulls the gondola 21a at the position P1 to the left. At this time, the gondola 21a on which the vehicle is placed is guided by the guide roller 27 and conveyed to the left side of the floor surface 3 without swinging. Eventually, the gondola 21a approaches the position P2, and when the gondola 21a further rises, the guide roller 25 is disengaged from the guide rail 16. The traveling sprocket 12 of the gondola 21a is guided by the guide chain 7 and meshes with the drive chain 11b. After this, the gondola 21a is driven by its own traveling sprocket 12 and is further conveyed upward. Thus, in FIG. 3, each gondola 21a to 21h moves in the cw direction.

When each gondola 21 is conveyed along the guide chain 7 as described above, the tension of the connecting chain 15 connecting the gondolas 21 changes. However, as shown in FIG. 6, each connecting chain 15 has a gondola suspension shaft 13
On the other hand, a shoe (not shown) which is rotatably connected by a connecting bearing 14 and which gives tension to the connecting chain 15 is provided on the lower left and right of the guide chain holding plate 6. Therefore, the gondola 21 can be smoothly transported without causing excessive tension or bending of the connecting chain 15. Further, the gondola 21 that has come to the uppermost part has a guide roller 27 as shown in FIG.
Since the guide rail 30 guides on the guide rail 30, the gondola 21 does not make a pendulum motion even if an earthquake occurs, and does not collide with an adjacent gondola.

Further, as shown in FIGS. 1 and 2, above the gondola drive mechanism 1, there is no large gear connected to the drive motor, as seen in the conventional multi-level parking apparatus. Therefore, the height of the parking tower can be made substantially the same as the height of the gondola drive mechanism 1 or the frame 2, and the gondola type multi-level parking device of this embodiment is more constructed than the conventional multi-level parking device having the same number of stored cars. The height of the object can be reduced. For example, if the number of gondola 21 is 8, the height of the parking tower is 8m.
It can be:

If the guide chain holding plate 6 is shaped such that the upper and lower edges thereof are horizontally long, a plurality of vehicles can be loaded and unloaded at the same time. That is, if the horizontal lengths of the guide chain holding plate 6 and the guide rail 16 shown in FIG. 3 are increased, for example, two gondola 21 can be grounded on the floor surface 3. In this case, the gondola type multi-level parking device has two gates, which improves the efficiency of loading and unloading. Further, in the gondola type three-dimensional parking apparatus of this embodiment, the gondola drive mechanism can be realized by using a commercially available chain and sprocket, and the cost of the three-dimensional parking apparatus can be greatly reduced. Even if the drive chains are cut, the gondola 21 can be prevented from falling off because they are connected to each other by the connecting chain.

[0042]

As described in detail above, according to the invention of claim 1 of the present application, a traveling sprocket is provided on the gondola suspension shaft, and the traveling sprocket is driven via a drive chain and a guide chain. . Therefore, the gondola drive mechanism can be assembled by using commercially available mechanical parts, and the manufacturing cost can be reduced. Further, since a plurality of gondola is conveyed along the guide chain, the gravity of the gondola is reduced in the drive chain, the tension of the drive chain can be reduced, and the gondola does not vibrate horizontally during suspension. Further, the height of the parking tower can be reduced compared to the number of gondola.

According to the second aspect of the present invention, the first guide rollers are provided at both ends of the gondola suspension shaft, and the first guide rails are provided along the lower edge of the holding plate. So when the gondola comes to the bottom of the circulation path,
Even if the traveling sprocket no longer engages with the guide chain or the drive chain, the weight of the gondola can be stably held.

According to the invention of claim 3 of the present application, the second guide roller is provided in the lower portion of the gondola, and the second guide roller is provided on the side surface of the holding plate.
Since the guide rail of is installed, the pendulum vibration does not occur when the gondola reaches the top of the circulation. When the gondola is at the bottom of the circulation, the vehicle can be loaded and unloaded stably.

According to the invention of claim 4 of the present application, since the first guide plate is provided in the vertical circulating portion of the drive chain, sliding friction of the drive chain is reduced, and the drive sprocket is less likely to come off from the drive chain. .
