Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-level multi-story parking apparatus, and more particularly, to a damping mechanism for a deceleration mechanism that decelerates and increases the driving force of a lifting drive source for raising and lowering a vehicle-mounted pallet at a high reduction ratio, Regarding soundproofing measures.

[0002]

2. Description of the Related Art Conventionally, as a multi-stage multi-dimensional parking apparatus of a type in which upper and lower pallets are integrally lifted, for example, as disclosed in Japanese Examined Patent Publication No. 5-34468, the pallets are arranged in two upper and lower stages. Two pallet elevating bodies that are integrated are installed side by side in a pit so that they can be elevated and lowered, and one elevating drive means installed between both pallet elevating bodies is driven to elevate and lower the pallet elevating bodies on both sides thereof. A multi-tiered (two-tiered) type multi-level parking device that can be switched is known.

That is, in this two-stage multi-level parking apparatus, as shown in FIG. 11, at the time of loading and unloading of the upper pallets b1 and b2 of the pallet elevators a1 and a2, the pallet elevator a1 on the right side in FIG. Lower pallet c
1 touches the bottom of the pit and the upper pallet b1
The pallet elevating body a1 is lowered so that is positioned at substantially the same height level as the vehicle entry surface. On the other hand, lower pallet c
11, when the pallet is moved in and out, the lower pallet c2 is located at substantially the same height level as the vehicle entry surface and the upper pallet b2 is located above the vehicle entry surface as in the left pallet elevator a2 in FIG. The body a2 is raised.

Then, each of the pallet lifting bodies a1, a2
The elevating and lowering driving means d for elevating and lowering the chain is provided with front and rear chain drive mechanisms h and h formed by winding two endless chains g and g around a pair of upper and lower sprockets e and f. The endless chains g, g can engage with the front and rear two positions on the inner side of the lower pallets c1, c2 of the pallet lifts a1, a2, and the pallet lifters a1, a2 can be connected to the upper and lower stages of the balance chains i1, i2. The pallets b1, c1, b2, c2 are configured to move up and down while maintaining the horizontal state.

Further, a geared motor j with a brake is employed as a drive source for moving up and down each of the pallet lifts a1 and a2, which makes it possible to lift the pallet lifters a1 and a2 having a large weight, and to operate the apparatus. To reduce the size as much as possible, a gear reduction mechanism incorporated in the motor j and a reduction mechanism m using a chain k are provided as means for increasing the driving force of the motor j. That is,
A drive sprocket n having two rows of teeth is attached to the output shaft of the geared motor j with a brake, and a driven sprocket p having a relatively large diameter is attached to a connecting shaft o connecting the sprockets e of the chain drive mechanism h to each other. The chains k, k are wound between the drive sprocket n and the driven sprocket p so that a high reduction ratio can be obtained. That is, when it is attempted to obtain a large driving force by increasing the reduction ratio only by the reduction gear mechanism incorporated in the geared motor with brake j or only the reduction gear mechanism m using the chain k, the mechanism becomes large. I will end up. And
In such a structure, the space between the pallet lifts must be increased in order to avoid interference between the speed reduction mechanism and the pallet lifts, which increases the space in the pit. In order to avoid such a situation, two speed reducing mechanisms are used together as described above.

[0006]

However, in such a structure, since the speed reducing mechanism is provided at two locations, there are also two sources of vibration and noise, and each of the speed reducing mechanisms emits light. There are problems that the generated vibration may adversely affect other members and that the driving noise of the entire device becomes loud due to noise.

It is also possible to provide a means for damping and soundproofing in the portion where the speed reducing mechanism is arranged, but it is difficult to provide such means without enlarging the space in the pit.

In other words, in the speed reduction mechanism provided in this type of multi-level multi-storey parking system, while obtaining a high speed reduction ratio,
It is required that vibration and noise be small without enlarging the space in the pit. However, the reality is that a deceleration mechanism that satisfies this demand has not yet been obtained.

The present invention has been made in view of the above points, and an object of the present invention is to reduce vibration and noise without increasing the space in the pit by improving the speed reducing mechanism. is there.

[0010]

In order to achieve the above-mentioned object, the present invention has only a reduction gear mechanism incorporated in a motor provided outside the pit, and is allowed to increase its size. It is possible to install a vibration control and soundproof structure while reducing the number of units.

Specifically, the invention according to claim 1 is a pallet elevating body which is arranged so as to be able to ascend and descend inside a pit recessed below the vehicle entry surface and has a pallet for mounting a vehicle in a plurality of upper and lower stages. The driving force for raising and lowering the pallet elevating body is decelerated at a high reduction ratio to increase and then output, and the driving means is disposed inside the pit and is provided between the driving means and the pallet elevating body. It is assumed that the multi-stage multi-story parking apparatus is provided with a drive mechanism that raises and lowers the pallet lifting body by the driving force from the driving means. Further, the drive means is installed in a drive means installation portion provided outside the pit and is connected to the drive mechanism by a drive force transmission member.

According to a second aspect of the present invention, in the multi-level multi-storey parking apparatus according to the first aspect, the drive means installation portion damps vibrations generated by the drive means, and noise generated by the drive means. The structure is provided with soundproofing means for shutting off.

According to a third aspect of the present invention, in the multi-level multi-storey parking apparatus according to the second aspect, the drive means installation portion is formed of a housing recess formed in the vehicle entry surface, and the soundproofing means is opened in the housing recess. It is configured with a lid that covers the.

According to a fourth aspect of the present invention, in the multistage multi-storied parking apparatus according to the third aspect, the driving means is a geared motor. Further, the vibration damping means is a vibration damping mat laid on the floor of the accommodating recess, and the geared motor is fixed to the upper surface of the accommodating recess, and the soundproofing means is a sound absorbing member provided on the inner wall surface of the accommodating recess and the inner surface of the lid. It is made of wood.

[0015]

According to the present invention, the following effects can be obtained in the present invention. In the invention according to claim 1, when the pallet elevating body is moved up and down, first, the driving means drives the
The driving force is decelerated at a high reduction ratio and increased. Then, the increased driving force is transmitted to the pallet elevating body via the driving force transmitting means and the driving mechanism, and the pallet elevating body moves up and down so that the desired pallet is located at substantially the same height as the vehicle entry surface. Vehicles can be loaded and unloaded. When the pallet elevating body is moved up and down in this way, the driving means generates vibration and noise accompanying the deceleration operation. However, since this driving means is provided outside the pit, it is assumed that the driving means is made large. However, the space inside the pit does not become large. Therefore, it is possible to obtain a high speed reduction ratio only by the speed reducing mechanism incorporated in the motor as the driving means. In other words, it is no longer necessary to use the speed reduction mechanism built into the motor and the speed reduction mechanism using the chain together as in the past.
Since the vibration and noise generating elements can be reduced, the vibration and noise of the entire device can be reduced.

According to the second aspect of the present invention, the vibration damping means and the soundproofing means provided in the drive means installation portion suppress the transmission of vibration and noise generated from the drive means in the drive means installation portion to the outside.

According to the third aspect of the present invention, since the drive means is disposed below the vehicle entry surface, that is, in the basement, the drive means can be installed outside the pit where it does not interfere with loading and unloading. Moreover, soundproofing is also performed by the lid that covers the opening of the accommodation recess.

According to the fourth aspect of the invention, the vibration generated from the geared motor as the driving means is absorbed by the vibration-proof mat to suppress the transmission to the outside, and the noise generated from the geared motor is the sound absorbing material. Thus, sound is absorbed and transmission to the outside is suppressed. For this reason, smooth driving and quietness can be satisfactorily obtained as the entire device.

One end of 1 is fixed, and the balance chain 11 is hung from the lower side of the guide sprocket 9 out of the pit 2 among the both guide sprockets 9 and 9 along the pallet receiving beam 8 of the lower pallet P2. After extending in the width direction, the guide sprocket 9 near the inside of the pit 2 is hung from above and fixed to the bottom surface of the pit 2. Then, the front and rear balance chains 11 and 11 are used to move the pallet lifting bodies 5 and 6 to the upper and lower pallets P1 and P, respectively.
It is designed to guide up and down while maintaining the horizontal state of 2.

Between the adjacent pallet lifts 5 and 6 in the pit 2, two main columns 12 and 12 are erected up and down at a predetermined interval. And these two main columns 12, 1
A shaft 17 for transmitting a driving force is bridged to the upper end of 2. Further, as shown in enlarged detail in FIG. 6, each of the main pillars 12 is composed of two pillars 2 made of steel having a substantially C-shaped cross section.
0 and 20 are arranged so that the opening sides thereof face each other, and both ends of the shaft 17 are fitted and inserted into the space between the columns 20 and 20, and the two upper sprockets 21 and 2 are fitted into the fitted portions.
1 is installed in parallel. Two lower sprocket wheels 22, 22 are also installed side by side at the lower end of the space between the two pillars 20, 20, and a pair of upper and lower sprocket wheels 21, 22 are provided with two endless chains 23, 23. Is wrapped around. Then, the upper sprocket 21, the lower sprocket 22, and the endless chain 23 constitute a chain drive mechanism 24 as a drive means in the present invention, and the chain drive mechanism 24 is provided on the front and rear main columns 12 and 12, respectively. There is.

The characteristic construction of this example is that the geared motor 13 with a brake is arranged as a driving means for transmitting a driving force to the upper sprockets 21 and 21 to move the pallet lifting bodies 5 and 6 up and down. is there. The arrangement of the geared motor with brake 13 will be described below.
As shown in FIG. 1, FIG. 3 and FIG. 4, on the floor surface 1 on the vehicle entry side of the present device A, that is, on the road in front of the vehicle, a flat surface is provided at a portion facing the intermediate position of each pallet elevating frame 5, 6. A motor accommodating concave portion 14 as a rectangular drive means installation portion is provided in a concave shape, and the geared motor 13 with a brake is accommodated in the motor accommodating concave portion 14. Further, a drive shaft 18 as a driving force transmitting member connected to an output shaft 15 of the geared motor 13 with a brake via a universal joint 16 is inserted into the vertical wall 14a of the motor housing recess 14 on the pit 2 side. Through hole 14b
Are formed. Then, the drive shaft 18 inserted into the through hole 14 b moves the shaft 1 inside the pit 2.
7 and is connected to the tip of the shaft 17 through a universal joint 19. The upper portion of the motor housing recess 14 is closed by a manhole 40 as a lid.

And, this geared motor 1 with a brake

As shown in FIGS. 8 and 9, a sheet-shaped sound absorbing material 41 is attached to each vertical wall surface of the motor housing recess 14, and the same is applied to the entire lower surface of the manhole 40. The sound absorbing material 41 is attached. As a result, soundproofing means for suppressing the noise emitted from the geared motor with brake 13 from leaking to the outside is configured. Further, in the geared motor 13 with a brake, a vibration-proof mat 43 is laid on the mortar material 42 fixed to the floor of the motor housing recess 14 by anchor bolts 44, and is fixed to the upper surface thereof. Further, a damping coupling 45 is interposed between the output shaft 15 of the geared motor with brake 13 and the universal joint 16. Each of the vibration damping structures constitutes a vibration damping means for suppressing adverse effects on each member in the pit 2 due to the vibration generated from the geared motor 13 with a brake.

Since the geared motor 13 with a brake is provided outside the pit 2, the internal space of the pit 2 does not become large even if it is made large. Therefore, the geared motor with a brake adopted here is used. The motor 13 can be a large one having a high reduction ratio. In other words, it is possible to obtain a high reduction ratio only by the motor 13 without increasing the space inside the pit 2, and therefore, reduction by a motor (gear reduction) and deceleration by using a chain as in the conventional case ( (Structure deceleration) is also used to obtain a high reduction ratio without increasing the pit space.

Therefore, the chain deceleration portion, which has been one of the sources of vibration and noise, can be eliminated.
Furthermore, it is possible to obtain a high reduction gear ratio while taking good vibration damping and soundproofing measures for the gear reduction portion which was another source of vibration and noise.

Reference numeral 46 in FIG. 3 is a drainage channel for discharging rainwater or the like that has entered the motor housing recess 14 during rainfall.

In this way, the front and rear chain drive mechanism 2
4, 24, the geared motor 13 with a brake, the shaft 17 and the like constitute a lifting drive device 25 as a lifting drive means for lifting the pallet lifting bodies 5, 6.

Further, as shown in enlarged detail in FIG. 7, both endless chains 23, 2 of each chain drive mechanism 24 described above.
3, one pallet hook 26 is bridged so as to stand between the two endless chains 23, 23, while the lower pallet P2 of the pallet elevators 5, 6 is moved forward and backward on the elevator drive device 25 side. Hooks 27, 27 that engage with the pallet lifting bodies 5, 6 are attached at two locations (see FIG. 5).

Then, the above-mentioned geared motor with brake 1
By transmitting the rotational torque of No. 3 to the front and rear chain drive mechanisms 24, 24 to drive the chain drive mechanisms 24 in synchronism with each other, the pallet hooks 26 try to invert the lower sprocket 22 and raise them. The pallet lifts 5, 6 are moved to the pallet lifters 5, 6 side, and the hooks 27 of the pallet lifts 5, 6 are engaged from below to cause the pallet lifters 5, 6 to move.
6 is moved up and down.

That is, the two-stage multi-level parking apparatus A of this embodiment
When the pallet elevators 5 and 6 are loaded and unloaded by the lifting drive device 25, the lower pallet P2 contacts the bottom surface of the pit 2 and the upper pallet P1 has substantially the same height as the floor 1. The pallet hooks 26 are engaged with the hooks 27 to lower the pallet lifting bodies 5 and 6 so that the lower pallet P2 is loaded and unloaded.
2 is located at almost the same height level as floor 1, and
The pallet hooks 26 are engaged with the hooks 27 so that the upper pallet P1 is located above the floor surface 1 to raise the pallet lifting bodies 5 and 6.

As described above, in the two-stage multi-storey parking system A of this embodiment, the chain drive mechanisms 24, 24 are normally or reversely driven by the switching drive of the elevating and lowering drive device 25, so that one side of the pallet is lifted. In a state in which the bodies 5 and 6 are separated from the pallet hooks 26 and grounded, the pallet lifting bodies 5 and 6 on the other side are moved up and down, and the vehicle C is loaded and unloaded from the pallet lifting bodies 5 and 6. There is.

2 to 4, reference numeral 31 is an operation panel provided at the upper end of the column 32 on the side of the loading / unloading entrance, and 3 in FIG.
3 is an endless chain 23 of the chain drive mechanism 24
In order to prevent the falling of the pallet lifting bodies 5, 6 due to the cutting of the pallet, a carrier drop prevention device provided near the upper end of each main pillar 12, 34 is a floor of the lower pallet P2 when the pallet lifting bodies 5, 6 are lifted. A lift stop limit switch for holding the surface 1 height, 35 is a lower stop limit switch for holding the upper pallet P1 at the floor 1 height when the pallet lifting bodies 5, 6 descend, FIG. 2 and FIG. Reference numeral 36 in 4 is a deck provided on the left and right sides of the pit 2 and in the middle thereof. In addition, car stops 37 are provided on both inner sides of the upper and lower pallets P1 and P2 so that the rear wheels are engaged and stopped so that the vehicle C stored in the back does not move.

Next, a description will be given of how the two-stage multi-level parking apparatus A having the above-described structure is loaded and unloaded.

As a premise, as shown in FIG. 2, it is assumed that the left pallet elevating body 5 is supported by the front and rear pallet hooks 26, 26 and is in an ascending state, and the right pallet elevating body 6 is in a descending state. . In this state, the lower pallet P2 on the left pallet lift 5 and the upper pallet P1 on the right pallet lift 6 are both at substantially the same height level as the floor surface 1 and can be loaded and unloaded.

In this state, when loading or unloading the upper pallet P1 of the left pallet elevating / lowering body 5,
By operating the operation panel 31 to drive the lifting drive device 25, the two endless chains 23, 23 of the chain drive mechanisms 24, 24 are synchronously driven in the counterclockwise direction, and the left pallet lifting body 5 is moved. The front and rear pallet hooks 26, 26 that are supported are lowered. With this,
The pallet lifting / lowering body 5 on the left side is lowered, and the lowering stop limit switch 35 detects this, and the lifting / lowering drive device 25 is stopped based on this detection signal. In this state, the upper pallet P1 of the left pallet elevating / lowering body 5 is positioned at substantially the same height level as the floor surface 1 so that it can be loaded and unloaded, and the lower pallet P2 is grounded and placed on the bottom surface of the pit 2.

From this state, this time, when loading and unloading the lower pallet P2 of the pallet elevator 6 on the right side in the lowered state, the operation panel 31 is operated to move the elevator drive device 25.
By driving the chain drive mechanism 24, 24
Each of the two endless chains 23, 23 of FIG.
The pallet hooks 26 supporting the pallets are separated from the hooks 27, inverted through the lower sprocket 22, and moved to the right pallet elevator 6 side. Then, the pallet hooks 26 are engaged with the hooks 27 of the right pallet lift 6 from below to support the pallet lifts 6, and the pallet hooks 26 are raised in this state. Along with this, the pallet lifting / lowering body 6 on the right side is lifted, and this is stopped by the lift stop limit switch 34, and the lift driving device 25 is stopped based on this detection signal. In this state, the upper pallet P1 of the right pallet lift 6 is located above the floor surface 1, and the lower pallet P2 is located at substantially the same height level as the floor surface 1 so that the pallet P2 can be loaded and unloaded.

Then, the driving force at the time of performing such an ascending / descending operation is decelerated at a high reduction ratio in the geared motor with a brake 13 and increased, and then the output shaft 15, the damping coupling 45, and the universal joint 16 are provided. And the sprocket 21, 21 on the front side through the drive shaft 18
Is further transmitted to the rear sprockets 21 and 21 via the shaft 17, whereby the driving force is transmitted to the rear sprockets 21 and 21.
The endless chains 23, 23 are driven to lift and lower the pallet lifting bodies 5, 6.

In such an operating state, since the deceleration mechanism portion which is the source of noise and vibration is only the geared motor 13 with the brake, there is only one source of noise and vibration associated with this deceleration. Has become. Further, the noise emitted from the geared motor 13 with a brake is absorbed by the sound absorbing material 41, and the motor housing recess 14 in which the geared motor 13 with a brake is installed is closed by the manhole 40. Leakage to the outside is suppressed. Further, the vibration generated from the geared motor 13 with brake is absorbed by the vibration-proof mat 43, and the vibration damping coupling 45 suppresses the transmission to the drive shaft 18 side. Therefore, the adverse effect of vibration on each member in the pit 2 is significantly reduced.

As described above, according to the configuration of the present example, the chain deceleration portion, which has been one of the sources of vibration and noise in the past, can be eliminated, and the other source of vibration and noise is generated. It is possible to obtain a high reduction gear ratio while taking good vibration damping and soundproofing measures for the gear reduction portion. Therefore, while achieving the high reduction ratio required for the reduction gear mechanism, it is possible to sufficiently satisfy the requirements that the vibration and noise are small without enlarging the space in the pit and greatly increasing the practicality of the drive system. Can be improved.

Further, in this example, since the geared motor 13 with a brake as a source of vibration and noise is installed on the lower side of the road in front of the pit 2 (on the left side in FIG. 3), the rear of the pit 2 (in FIG. 3). There is almost no transmission of vibration and noise to the right side), and this structure is particularly effective when there is a house behind the pit 2.

In the above embodiment, the pallet elevating bodies 5 and 6 have the two-tiered upper and lower tiers, but as shown in FIG. 10, the upper pallet P1 and the lower pallet P2 are combined. The present invention can be applied even to the case of a three-stage multi-level parking apparatus A having three upper and lower tiers with a middle pallet P3 provided therebetween. In this case, the upper pallet P1 is placed on the floor surface 1 with the pallet lifters 5 and 6 in the grounded state.
The middle pallet P3 and the lower pallet P2 are positioned in the pit 2 at the same height level as. Note that, in FIG. 10, the same components as those of the two-stage multi-level parking device A are denoted by the same reference numerals, and detailed description thereof will be omitted.

Further, in the above embodiment, the case where two pallet lifting bodies 5 and 6 are arranged side by side is shown, but it is also possible to arrange three or more pallet lifting bodies 5 in parallel. 5,
The lifting drive device 25 may be installed between the six as described above.

Further, in the above embodiment, the motor accommodating recess 14 is provided on the front roadway, but it may be provided on the rear or side floor surface.
