Document Type and Number:
Japanese Patent JPH01101293
Kind Code:
A
Abstract:
PURPOSE:To reduce the price of an instrument by mounting the guide of a communication guide, a rod, a spring pressing the rod against an engaged part, a means for moving the rod in the opposite direction to the movement, a stopper preventing the rod from moving, and a detector. CONSTITUTION:When a recovery equipment is thrown into the sea with a crane with the chamber of a hydraulic cylinder 31 low in pressure and a contactor contacts a sailing body 10, a detector is lifted to elevate the stopper 28 connected thereto. As a result, a rod 35 passes through an opening 26a by the load of a spring 32, projecting toward a lifting tool 11 to engage therewith. On the contrary, when the recovery equipment is lifted up with the crane, the rod 35 is engaged with the lower face of a flange 11b so that the sailing body 10 is also lifted. The sailing body 10 is lowered on an accomodation table, the rod 35 is lowered and separated from the flange 11b. Under such condition, when a hydraulic pump is connected to a connection port 31a and the rod 35 is retired by supplying pressure oil, the detector is lowered due to its own weight and a stopper 28 is also lowered to close the opening 26a. Therefore, the entire operation can be executed mechanically, whereby reducing the price of the recovery equipment.
