Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for detecting a break in a suspension cable of an elevator of a parking device.

[Conventional technology]

In a parking system equipped with a parking room for storing pallets loaded with automobiles and an elevator that transports pallets from the entrance / exit floor to the parking room, a serious accident caused by the cutting of a lifting line that suspends the four corners of the elevator As a means to prevent
A set of two suspension cables for suspending each corner of the lift,
The structure was such that when one suspension line was cut, the other suspension line could sufficiently support the load.

[Problems to be solved by the invention]

However, such means can prevent the elevator from falling, but cannot immediately stop the operation of the parking device at the time of cutting the hanging rope, and other parts of the parking device such as an automobile and a pallet are cut off by the cut hanging rope. There was a risk of causing damage to the device.

The present invention solves such a problem in the elevator of the parking device, and detects the breakage of the suspension line, and immediately stops the operation of the parking device, thereby preventing damage to the automobile and other parts of the parking device. An object of the present invention is to provide a device for detecting a breakage of a suspension cable of an elevator of a parking device which can be used.

[Means for solving the problem]

The present invention is directed to a parking device having a parking room for storing a pallet loaded with automobiles, and an elevator for suspending the elevating platform by means of a hanging cable and elevating the platform to transport the pallet from the loading / unloading floor to the parking room. At four corners, a hanging cable attachment is pivotally mounted on a horizontal pivot, and a pair of suspension cables is attached to the hanging cable attachment so that when one of the hanging cables is cut, the hanging cable attachment is tilted. The above-mentioned problem is solved by mounting the sensors at a distance from each other in a direction perpendicular to the vertical plane passing through the pivot, and by providing a detector for detecting the tilt of the hanging cable attachment when the hanging cable is cut.

[Action]

In this detection device, when one of the suspension cables is cut, the suspension cable fixture suspended by the two suspension cables loses its balance,
Tilt to one side about the axis. The detector detects this tilt and outputs an alarm signal, and the operation of the parking device is stopped by the alarm signal. Therefore, it is possible to prevent damage to other portions of the parking device such as the pallet due to the cut suspension cable, and to take quick recovery measures.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a parking device having an elevator, FIG.
FIG. 3 is a plan view of the lifting platform, FIG. 3 is a front view of a hanging line cutting detecting device according to an embodiment of the present invention, and FIG. 4 is a side view of the hanging line cutting detecting device.

As shown in FIG. 1, the parking device 1 includes a multi-layered parking room 13 for storing a pallet 11 loaded with an automobile 2 and an elevator 3 for transporting the pallet 11 from the entrance / exit floor 4 to the parking room 13 for each layer. Have. Pallets 11 on both sides of parking room 13
A support beam 16 for supporting the wheels 15 is provided. The elevator 3 includes a lifting platform 12 on which a pallet 11 is mounted, a lifting cable 14 for suspending the lifting platform 12 to raise and lower the lifting space 5, and an elevator driving device (not shown).

As shown in FIG. 2, hanging lines 14 are attached to the lifting platform 12 at four corners.

As shown in FIG. 3 and FIG. 4, a hanging cable attachment 20 is pivotally attached to the lifting platform 12 by a horizontal pivot 21. A pair of hanging cables 14 ( 14L, 14R) are installed. Thus, the two suspension cables 14L, 14R are attached to the attachment points 22L, 22 so that the suspension cable fixture 20 tilts when one suspension cable 14 is cut.
The Rs are mounted spaced apart from each other in a direction perpendicular to the vertical plane passing through the pivot.

A striker 23 is provided on the suspension cable attachment 20 so as to protrude to the side. Above and below the distal end of the striker 23, detectors 24 for detecting the tilt of the cable attachment 20 when the cable 14 is cut. Is provided. Reference numeral 25 denotes a detector mounting base, reference numeral 26 denotes a guide roller for preventing the vertical movement of the elevating base 12, and reference numeral 27 denotes a guide roller.

When one of the suspension cables 14 is cut, the suspension cable fixture 20 suspended by the two suspension cables 14L and 14R loses its balance, and is pivoted.
Tilt right or left around 21. When the sling attachment 20 tilts right and left, the tip of the striker 23 moves up and down, and the detector 24 detects this movement and outputs an alarm signal. The operation of the elevator 3 and other machines of the parking device 1 are stopped by this alarm signal. Therefore, damage to the other parts of the parking device 1 such as the pallet 11 due to the cut suspension cable 14 is prevented. In addition, if a display device such as a buzzer or an alarm lamp is operated by the alarm signal, it is possible to notify the administrator of the disconnection of the hanging cable, and prompt recovery measures can be taken.

[Effect of the invention]

Since the hanging line cut detection device of the present invention is configured as described above, it is possible to prevent the damage to other parts of the parking device by detecting the cut of the hanging line and immediately stopping the operation of the parking device. it can.
