Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a balance weight device for a multilevel parking device.

[0002]

[Prior Art]

 As an example of a three-dimensional parking device, parking shelves accommodating vehicles are arranged on both sides of a hoistway of a vehicle hoistway in multiple stages along the hoistway, while the lowest part of the hoistway is used for vehicle entry. An elevator-type vehicle, which is a part of the vehicle, is configured to connect the loading section and the parking shelves to each other by the vehicle lift (see Japanese Patent Laid-Open No. 1-207573). In such a parking device, the vehicle lifting platform has four corners suspended by four wire ropes from a hoisting device above the hoistway, and a constant weight balance weight is provided to balance the load on the vehicle lifting platform side. Therefore, the driving force applied to the wire rope is usually reduced.

[0003]

[Problems to be solved by the device]

 However, while the weight of the vehicle mounted on the vehicle lifting platform changes depending on the vehicle type, the weight of the balance weight is constant. Therefore, regarding the hoisting device, the capacity of the drive motor must be determined by assuming the heaviest vehicle, and normally the vehicle mounted on the vehicle lift is lightweight and there is a margin for the motor. Despite this, large hoisting equipment must be used.

That is, an object of the present invention is to miniaturize the hoisting device by preventing the load applied to the hoisting device from being greatly changed even if the weight of the above-mentioned vehicle is largely changed.

[0005]

[Means for Solving the Problems]

 The present invention addresses such a problem by making it possible to increase or decrease the weight of the balance weight according to the weight of the vehicle mounted on the vehicle lift.

That is, the means for solving the above-mentioned problems are as follows: a loading section for loading a vehicle for parking; a parking section provided above or below the loading section for accommodating the vehicle; A vehicle ascending / descending platform for moving up and down to move a vehicle in and out of the parking section, a hoisting device for driving the wire rope so that the vehicle elevating / descending platform ascends and descends, and a driving force to be applied to the wire rope is reduced. A balance weight device for a three-dimensional parking device having a balance weight that is balanced with the load on the side of the vehicle lift through the hoisting device as described above, and the weight liquid provided in the balance weight is put into the balance weight device. A weight tank; a fixed tank provided at a fixed position near the hoistway of the balance weight to store the weight liquid; and the weight tank A pipe that connects the fixed tank and a pump that is provided on the pipe and that is driven so as to increase or decrease the liquid amount of the weight tank according to the weight of the vehicle mounted on the vehicle lift Is a feature.

The pipe connecting the weight tank and the fixed tank may be two pipes, and each pipe may be provided with a supply pump and a discharge pump for the weight liquid. Of course, it is also possible to use one pipe as described above and provide pumps for both supply and discharge.

Further, as the liquid for the weight, water is preferable because it is simple and inexpensive, but other liquid having a larger specific gravity than water can be used.

[0009]

[Action]

 In the case of the above balance weight device, the weight of the balance weight can be changed by supplying and discharging the weight liquid from the fixed tank to the weight tank of the balance weight by the pump. The pump is driven so that the amount of liquid in the weight tank is increased or decreased according to the weight of the vehicle on which the vehicle lift is mounted, so that the driving force required for the wire rope is applied regardless of the weight of the vehicle. It can be set to a substantially constant value. In other words, when a heavy vehicle is mounted on the vehicle lift, the liquid amount in the weight tank is increased so that the driving force required for the wire rope becomes the same as when a lightweight vehicle is mounted. be able to.

[0010]

[Effect of the device]

 Therefore, according to the present invention, the balance weight is provided with a weight tank for storing the weight liquid, and this tank and the fixed tank are connected by a pipe, and the weight of the vehicle mounted on the vehicle lifting platform is connected to the pipe. Depending on the weight of the vehicle, the weight of the balance weight is changed according to the weight of the vehicle. Regardless of fluctuations, the value can always be set to a substantially constant value, and the hoisting device can be downsized.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. -Overall Configuration of Multilevel Parking Device-In FIG. 1, 1 is a parking tower, and 2 is an entrance / exit of a vehicle W. On the left and right sides of the parking tower 1, a plurality of parking shelves 5 accommodating the vehicles W are vertically arranged in a layered manner to form a parking section, and the vehicles W are mounted between the left and right parking sections. It is formed in the hoistway of the vehicle lifting platform 6 that moves up and down. Each of the parking shelves 5 is vertically long so that two vehicles W can be accommodated in a column.

The vehicle lift 6 is provided with a slide stand 7 on which the vehicle W is placed and which is slidable in the vehicle longitudinal direction. The slide table 7 is provided with a conveyor for transferring the vehicle W between the vehicle lift table 6 and each of the parking shelves 5.

The vehicle lift table 6 is lifted up and down with four corners thereof being suspended by a wire rope 8 for the vehicle lift table. Therefore, a hoisting device 11 for hoisting and unwinding the wire rope 8 via a sheave 9 is provided above the hoistway. Further, a wire rope 13 for weight is hung from the hoisting device 11 to the side of the hoistway via a sheave 12, and a balance weight 14 is hung on the wire rope 13. The balance weight 14 is loaded on the vehicle lift table 6 side (vehicle lift table 6 and vehicle lift table 6 via the hoisting device 11 so that the driving force applied to the vehicle lift wire rope 8 is reduced. The weight of the vehicle W).

The hoisting device 11 includes a drum 15 to which the wire ropes 8 and 13 described above are connected, and a drive motor 17 that rotationally drives the drum 15 via a speed reducer 16.

-Regarding Vehicle Warehousing-The vehicle W loaded from the loading / unloading port 2 is moved to the slide base 7 of the vehicle lift 6. Then, the vehicle W is lifted and conveyed to the planned parking rack 5 by the vehicle lift 6 and is transferred from the vehicle lift 6 to the parking rack 5. At this time, when the vehicle W is housed on the front side of the parking shelf 5 in the vehicle entry direction, the slide base 7 is slid to the front side. When the vehicle W is leaving, the operation is the reverse of the above-mentioned entering.

-Balance Weight Device- The configuration of the balance weight device is shown in FIGS. 2 and 3. That is, the balance weight 14 described above is provided with a weight tank 21 for containing a weight liquid. On the other hand, the parking tower 1 is provided with a fixed tank 22 for storing the above-mentioned weight liquid near the hoistway of the balance weight 14.

The weight tank 21 and the fixed tank 22 are a supply pipe 23 for supplying the liquid from the fixed tank 22 to the weight tank 21, and a discharge pipe for discharging the liquid from the weight tank 21 to the fixed tank 22. And 24. One end of each of the pipes 23, 24 is passed through a pipe guide 25, 26 having one end fixed to a fixed position of the parking tower 1. The pipe guides 25 and 26 regulate the slack state of the pipes 23 and 24 so that the pipes 23 and 24 do not sag and are not entangled with peripheral members when the balance weight 14 moves up and down.

The supply pipe 23 is provided with a weight liquid supply pump 27, and the discharge pipe 24 is provided with a weight liquid discharge pump 28 and a discharge valve 29. Further, in order to control the driving of the supply and discharge pumps 27, 28 and the discharge valve 29, a vehicle weight detection sensor for detecting the weight of the vehicle W mounted at the front and rear ends of the vehicle lift table 6. (Load cells) 30, 30 are attached, and a liquid level sensor 31 for detecting the liquid level of the weight liquid stored in the weight tank 21 is attached. These sensors 30, 31 are the pumps described above. 27, 28 and the discharge valve 29 are connected to a control device 32 which outputs a control signal.

That is, the control device 32 is set according to the vehicle weight so that the difference between the loads acting on the vehicle lift wire rope 8 and the weight wire rope 13 is within a predetermined value. The liquid level data of the weight tank 21 is provided, and the liquid level is calculated based on the value detected by the vehicle weight detection sensor 30. The pumps 27, 28 are adjusted so that the liquid level of the weight tank 21 becomes the liquid level. And the discharge valve 29 is feedback controlled.

-Effects of Balance Weight Device- Therefore, when the vehicle W on which the vehicle lift 6 is mounted is heavy, the liquid level of the weight tank 21 is determined based on the value detected by the vehicle weight detection sensor 30. The supply pump 27 is driven such that the balance weight 14 becomes heavier in proportion to the weight of the vehicle W in question. On the other hand, when the mounted vehicle W is a lightweight vehicle, the discharge valve 29 is opened so that the liquid level of the weight tank 21 is lowered based on the value detected by the vehicle weight detection sensor 30, and the discharge pump 28 is operated. It is driven, and as a result, the balance weight 14 becomes lighter according to the weight of the vehicle W in which the balance weight 14 is mounted.

Therefore, the difference between the loads acting on the vehicle lift wire rope 8 and the weight wire rope 13 is always within a predetermined value regardless of the weight of the vehicle W. As a result, the load on the drive motor 17 of the hoisting device 11 can be reduced. That is, a small capacity motor can be used as the drive motor 17, and the hoisting device 11 can be downsized.

Although the above embodiment relates to the elevator type parking apparatus, the present invention is of course applicable to other types of multi-level parking apparatus having a vehicle lift.
