ことになる。 In a parking device with such a mechanism, even if one of the hoisting chains 11, 12, 13, and 14 breaks, it is extremely dangerous to leave it as is, and it is desirable to install a chain breakage detection device for each chain. However, if the detection devices were installed separately for each, as the number of hoisting chains increases, it would take too much time and effort to adjust the installation.
本考案は、上記の点に鑑みなされたもので、単

3 and a sliding part 45 with shoes 57 and 58 at the tip.
It consists of The storage box 43 is fixed to the frame 46 of the parking device with bolts 47 and nuts 48, and micro switches 41 and 42 are bolted to support stands 49 and 50 fixed inside the storage box via brackets 51 and 52, respectively. ing.
Hollow spring seats 53 and 54 are fitted into the upper surface of the storage box 43, and rods 55 and 56 pass through the spring seats 53 and 54 in a parallel manner so as to be able to slide freely in the vertical direction, respectively. Lower end portions 55a, 5 of 56
6a is the roller 4 of the micro switches 41 and 42
The structure is such that it can be moved without touching 1a and 42a. That is, when the rods 55, 56 are in the downward movement position, the lower ends 55a, 56a are in contact with the rollers 41a, 42a of the microswitches 41, 42, respectively.
The rollers 41a and 42a of Nos. 1 and 42 are in a non-contact state. On the other hand, the upper ends of the rods 55, 56 have shoes 57, 5 in contact with the chains 13, 14.
8 is fixed, and these shoes 57 and 58 are attached to the storage box 4.
It is guided by guide rails 59 and 60 erected on the upper surface of 3. Also, shoes 57, 58 and spring seat 53,
Springs 61 and 62 are inserted between 54,
Due to the tension of chains 13 and 14, shoes 57 and 5
When 8 is no longer pushed downward, this spring 6
The shoes 57 and 58 move upward together with the rods 55 and 56 due to the spring pressure of the rods 5 and 5.
5, 56 and the rollers 41a, 42a of the micro switches 41, 42 are separated from each other.

トの昇降ができないようにする。 Because of this structure, if the pallet 10 is reliably suspended from the four hoisting chains 11 to 14, the tension of the hoisting chains 11 to 14 will cause the shoe to be held down along with the rods against the spring pressure of the spring. Then, the micro switch is operated to allow the pallet 10 to move up and down freely by utilizing the drive circuit (not shown) of the hoist 15, but in the unlikely event that any of the four hoist chains breaks and the tension is reduced. When it runs out, not only does the well-known fall prevention device work, but the shoe that was in contact with the relevant chain will fly upwards with the rod due to the spring pressure, and the lower end of the rod will separate from the micro switch roller, causing it to wind up. Machine 1
The drive circuit No. 5 is cut off to prevent the pallet from being raised or lowered in a state where it is hung on one side.

きわめて簡単な安全装置を得ることができる。 In this invention, in a parking device in which the four hoisting chains are suspended from the four corners of a pallet, chain breakage detection devices are placed together in the area where at least two hoisting chains are placed close to each other, making it easy to wire the switch. At the same time, the chain breakage detection mechanism can be extremely simplified, and an extremely simple safety device can be obtained.
