Title:
CONNECTING DEVICE
Document Type and Number:
Japanese Patent JP3725309
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To carry out sure engaged operation of projecting and recessed members, even when their relative speed is fast, in a connecting device that connects a lifted boat and wire rope by the engagement of the projecting member of the tip of the wire rope and the recessed member of the lifted boat side, which has a boat lifted device that lowers a boat lifted by a wire rope.
SOLUTION: This coupling device has a projecting member fixed to the tip of a steel wire rope 1, a recessed member 3 that engages with this projecting member, and a guide member 5 fixed above this recessed member 3. The tire members a 9A and 9B are fixed to the output shafts 8A and 8B of the electric motors 7a and 7B, which are on this guide member 3. In order to engage the projecting member and recessed member, when the wire rope 1 feeds into the lead hole 3B of the recessed member 3 and the notch part 5C of the guide member 5, the wire rope 1 is drawn into the lead hole 3B and toward the notch 5c side by the frictional force of the tire members 9A, 9B that simultaneously rotate in opposite directions.
