Abstract

PROBLEM TO BE SOLVED: To collectively arrange apparatuses of a driving part in one place by horizontally holding a carrier by longitudinally and laterally moving weights on the basis of detecting data of angle sensors arranged in the carrier suspended/held in one place. SOLUTION: Angle sensors 22 to detect an inclination are arranged in the symmetrical two corners among the four corners in a bottom part of a carrier 3. A weight 24 to move in the longitudinal direction by a longitudinally moving motor 23 and a weight 26 to move in the lateral direction by a laterally moving motor 25, are also arranged in the bottom part of the carrier 3. Since the carrier 3 is suspended/held in one place by a suspending cable connecting to a suspending holding point, a gravity center position moves by a stopping position or the like of an automobile, and a balance of the carrier 3 changes. When an inclination changes, the longitudinally moving motor 23 and the laterally moving motor 25 are controlled on the basis of detecting data of the angle sensors 22, and the weights 24 and 26 respectively longitudinally and laterially move by a necessary distance, and the balance of the carrier 3 is automatically restored, and is returned to a horizontal condition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for maintaining the balance of a transport device for controlling a transport device of a lift device of a mechanical parking facility to be kept horizontal.

[0002]

2. Description of the Related Art As shown in FIG. 3, a multi-stage parking room 9 is provided as a parking facility for parking a large number of automobiles within a predetermined site area. A mechanical parking facility 1 that transports and stores a car by a lifting device 2 is used.

Conventionally, the lifting and lowering device 2 of the mechanical parking equipment 1
In FIG. 4, as shown in FIG. 4, the transporter 3 for loading and transporting the automobile 10 is usually adapted to move up and down the hoistway 4 by suspending the four corners with a hanging rope 6 such as a wire rope or a chain. .

[0004]

However, in this structure, since the hanging ropes 6 are attached to the four corners of the transporter 3, the driving unit 11 provided on the upper part of the lifting / lowering device 2 can cover a wide range of required equipment. The layout must be complicated, and the space in the machine room 8 must be increased.

On the other hand, if the transporter 3 is hung at one place, only one hanging cable 6 is required, and the equipment of the drive unit 11 can be collectively arranged at one place. Can also be reduced.

However, if the transporter 3 is suspended at one place, the transporter 3 is likely to be inclined. Therefore, the transporter 3 needs to be provided with a guide for upper and lower sides to maintain the horizontal position. In some cases, the moving direction of the pallet 7 is restricted, and the pit 12 below the lifting device 2 needs to be deepened. When guides are provided on the upper and lower sides, if the balance of the transporter 3 is deteriorated due to the stop position of the automobile 10, the presence or absence of the pallet 7, etc., the friction of the guide portion increases, causing an increase in resistance and noise. is there.

SUMMARY OF THE INVENTION The present invention solves such a problem in a lifting device for a mechanical parking facility, and can maintain the horizontal state even if a transporter is suspended at one place, thereby reducing the number of devices of a driving unit. An object of the present invention is to provide a transport device balance holding device that can be collectively arranged at a location, can reduce the space of a machine room, can increase resistance due to friction of a guide portion, and can prevent noise. I do.

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided an apparatus for maintaining the balance of a transporter, comprising: an elevator for parking equipment, which suspends the transporter at one place and detects an inclination angle on the transporter; The above problem is solved by providing a weight that moves back and forth and left and right so as to hold the transporter horizontally based on the detection data.

Since the transporter is hung at one place, if the balance of the transporter is deteriorated due to the stop position of the automobile or the presence of a pallet, the transporter tends to tilt, but the tilt angle of the transporter is always detected by an angle sensor. When the inclination changes, the weight moves back and forth, left and right by a required distance based on the detection data of the angle sensor to restore the balance of the transporter and return to a horizontal state.

Therefore, no special guide or the like is required for the transporter, and only a simple guide similar to the case of supporting the four corners may be used, and an increase in resistance due to friction of the guide portion and noise can be prevented.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the structure of a transporter of a lifting device for parking equipment according to an embodiment of the present invention, and FIG.
Is a bottom view of the transporter.

This transporter 3 is similar to that shown in FIG.
A multi-stage parking room 9 is provided.
It is used in the mechanical parking equipment 1 that transports and stores the automobile 10 by the lifting device 2, and a suspension rope 6 such as a wire rope or a chain is connected to a suspension point 21 at the center of an upper suspension frame 20. It is suspended at one of the suspension points 21.

As shown in FIG. 2, an angle sensor 22 for detecting an inclination angle is provided at the bottom of the transporter 3 at two symmetrical corners among the four corners. A weight 24 that moves in the front-rear direction by a motor 23 for front-rear movement and a weight 26 that moves in the left-right direction by a motor 25 for left-right movement are provided at the bottom of the transporter 3.

The front-rear movement motor 23 and the left-right movement motor 25 are driven and controlled based on detection data of the angle sensor 22. Since the transporter 3 is suspended at one place by the suspension cable 6 connected to the suspension point 21, the position of the center of gravity moves depending on the stop position of the automobile 10, the presence or absence of the pallet 7, and the like, and the balance of the transporter 3 changes. . When the balance deteriorates, the carrier 3 tends to incline. However, the inclination angle of the carrier 3 is constantly detected by the angle sensor 22, and when the inclination changes, the weights 24, 26 based on the detection data of the angle sensor 22.
Moves back and forth, left and right, respectively, a required distance, and automatically restores the balance of the transporter 3 to return to a horizontal state.

Therefore, no special guide or the like is required for the transporter 3, and only a simple guide similar to the case where the four corners are supported may be used.
Noise is also prevented. The pit 1 at the lower part of the lifting / lowering device 2 is not restricted by the entry / exit of the car 10 or the moving direction of the pallet 7.
There is no need to make 2 deeper.

Since the transporter 3 is hung at one place, only one hanging cable 6 is required, and the equipment of the drive unit 11 can be arranged at one place, and the space of the machine room 8 is reduced. be able to.

[0017]

As described above, the balance maintaining device for a transporter according to the present invention can maintain a horizontal state even if the transporter is hung at one place in an elevating device of a mechanical parking facility. Therefore, the devices of the drive unit can be arranged at one place, and the space in the machine room can be reduced. In addition, it is possible to adopt a structure that is not restricted by the direction of movement of the pallet and the movement of the car in and out, and it is possible to prevent an increase in resistance due to friction of the guide portion and noise.
