DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a multi-story parking device, which serves both as a device for preventing the pallet from falling and a device for preventing the pallet from swinging back and forth and right and left when the vehicle is traversing. is there.

[0002]

2. Description of the Related Art Conventionally, as a device for preventing a pallet from dropping in a multi-story parking device, there is a device disclosed in Japanese Utility Model Application Laid-Open No. 61-76.
When the chain 25 breaks as shown in No. 054, the engaged member 43 engages with the engaging hook 46 and the pallet 1
Japanese Patent Laid-Open Publication No. Hei 2-2 discloses a device for preventing falling of the pallet 5 and preventing the pallet from swinging back and forth and right and left when the pallet is traversing.
As shown in JP-A-79876, the steady rest pin 25 of the suspension frame 26 is engaged with the hole 24b of the elastic plate 24C of the pallet 23 to form a steady rest device.

[0003]

For this reason, since the fall prevention device for the pallet and the steadying device when the pallet is traversing are separately provided, the cost is increased. Accordingly, an object of the present invention is to reduce the cost by using both a pallet fall prevention device and a pallet steady rest device.

[0004]

According to the present invention, there is provided a multi-story parking apparatus in which a pallet on which a vehicle is mounted is suspended from a traversable suspension so as to be able to move up and down. , A bracket is suspended, and a locking member is provided on the bracket so as to be able to move forward and backward by an operating device.A stay is provided on the pallet at a position facing the bracket, and the stay is provided on the stay with the locking member. When the pallet descends, the bracket is provided with an engaging portion that engages when the pallet descends. Further, the bracket comes into contact with the stay in the front-rear direction where the stay comes into contact when the pallet swings back and forth, and contacts the stay when the pallet swings left and right. It is characterized in that it is provided with a contact portion in the left-right direction.

[0005]

When the chain is broken while the pallet suspended from the suspension is stopped, the pallet falls, but the engaging portion provided on the stay of the pallet is provided with the engaging member of the operating device provided on the bracket of the suspension. And the pallet is prevented from falling. Next, when the hanging body traverses, the pallet suspended from the hanging body swings back and forth and left and right, but the stay of the pallet is in contact with the front and rear contact portions of the bracket of the hanging body and the left and right contact portions. To prevent the pallet from swinging back and forth and right and left.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a four-stage four-row multi-story parking device 1, which comprises a lower stage 2, a second stage 3 a and a third stage 3.
b, middle row 4, upper row 4, first row 5, and second row 6
The vehicle can be parked in the middle row 6 composed of the third row 6a and the third row 6b and in the respective sections composed of the fourth row 7.

The parking device 1 includes a left support 8a, an intermediate support 8b, a right support 8c, two-stage frames 9a and 3b.
The middle frame composed of the step frame 9b and the upper frame 10 are formed in a lattice shape. A pallet 11 is provided on the lower tier 2 so as to be able to traverse, and a rectangular suspension 12 is provided on the middle frame 9 so as to be traversable, and a pallet suspended from the suspension 12 by a chain 13. 14 is provided so as to be able to move up and down.

A rectangular suspension 15 is fixed to the upper frame 10, and a pallet 17 suspended by a chain 16 is provided on the suspension 15 so as to be able to move up and down.
In the lower 2 and middle 3 sections of the first row 5, the pallets 17 are moved up and down to eliminate the pallets 12 and 11 to secure a space. A fall prevention device 18 for preventing the pallet 14 from falling when the chain 13 is broken between the hanging body 12 and the pallet 14 and a pallet 14 swinging back and forth and right and left when the hanging body 12 traverses. A safety device 20 is also provided, which also serves as a steady rest device 19 for preventing the occurrence of the vibration.

Next, the safety device 20 will be described.
Reference numeral 1 denotes a bracket suspended vertically from front to back and left and right of the suspension body 12, and the bracket 21 includes left and right beams 21a and 21b and an intermediate beam 21.
c and has an H-shaped horizontal section. The intermediate digit 2
An actuator 23 that allows the locking member 22 to move forward and backward is attached to 1c.

Reference numeral 24 denotes a stay standing upright and left and right of the pallet 14 at a position opposed to the bracket 21. The stay 24 is inserted between the left and right girders 21a and 21b of the bracket 21 when the pallet 14 is raised. Is provided with an engaging portion 25 which can be freely disengaged as the locking member 22 advances and retreats. The locking member 22 of the actuating device 23 provided on the bracket 24 and the engaging portion 25 of the stay 24 provided on the pallet 14 constitute a fall prevention device 18. When the hanging body 12 traverses, the stay 24 is A steadying device 19 that contacts an angle-shaped front-rear contact portion 26 provided below the intermediate girder 21 c of the bracket 21 and the stay 24 abuts a left-right contact portion 27 of the left and right beams 21 a and 21 b of the bracket 21. Is formed.

As shown in FIG. 3 and FIG.
The rotation of the disk 29 by the operation of the motor 28 causes the locking member 22 to pass through the link plate 31 having the elongated hole 30 and move the solid line position to the advanced position and the two-dot chain line position to the one-dot chain line position. It is designed to advance and retreat to the evacuation position,
The pallet 14 is engaged with the engaging portion 25 when the pallet 14 is lowered at the advanced position of the locking member 22, and the pallet 14 is allowed to be lowered at the retracted position of the locking member 22.

The operation of the present invention having the above-described structure will be described below. First, while the pallet 14 is stopped, the chain 1
When the pallet 14 is cut, the pallet 14 falls.
An engaging portion 25 of a stay 24 is provided on a bracket 21 suspended from the suspending body 12, and is engaged with a locking member 22 at an advanced position to prevent the pallet 14 from dropping.

Next, when the hanging body 12 is traversed,
The pallet 14 suspended on the pallet 14 swings in the front-rear direction and the left-right direction due to inertia, vibration, and the like, but the stay 24 erected on the pallet 14 is in contact with the bracket 21 suspended from the hanging body 12 in the front-rear direction. 26 is prevented from swinging in the front-rear direction, and the stay 24 is connected to the left and right contact portions 2 of the bracket 21.
7 is also prevented from swinging in the left-right direction.

[0014]

As described above, according to the present invention, a fall prevention is provided by a locking member provided on a bracket suspended from a hanging body and capable of moving forward and backward, and an engaging portion provided on a stay provided on a pallet. Since the device is configured, and the stay and the contact portion in the front-rear direction and the contact portion in the left-right direction provided on the bracket constitute a steady rest device, the fall preventing device and the steady rest device are also used and provided separately. The cost is lower than that.
