Description

[Detailed Description of the Invention] Conventionally, as a method for collecting floating objects on the water, a method using a lifting device such as a crane installed on a mother ship has been adopted, but in most cases, a method using a lifting device such as a crane installed on a mother ship has been adopted. I was borrowing a hand.

However, as offshore floating objects become larger, the metal fittings that connect the offshore floating objects and the slings become larger, and if the relative movement between the offshore floating objects and the mother ship is taken into consideration, handling problems may arise, making work difficult. However, there were also drawbacks that could pose a danger to divers. The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and by attaching a connecting device main body to the tip of a hanging element and pulling the device main body downward by its own weight, for example, floating on the ocean. The object of the present invention is to provide a coupling device that can be connected and released without the aid of a diver.

The present invention will be described below with reference to the embodiments shown in the drawings. Reference numeral 1 is a connecting device that is attached to a hanging element 2, and by engaging a claw 5 with a connected hardware 4 attached to an offshore floating object 3, the floating object It is possible to connect with 3.

The pawls 5 have a ÷circular shape, and are arranged in the same shape with respect to the pawl operating shaft 6. A protrusion 7 is provided on the upper surface of the base of each pawl 5, and a projection 7 is provided between the adjacent protrusions 7. A spring 8 is attached to the spring 8, and the base of each claw 5 is attracted in the axial direction of the claw actuating ratchet 6 by the spring 8, and the taper 9 formed on the lower side of the base of the claw 5 is caused to actuate the claw. Ampulla 1 formed at the bottom of shaft 6
They are pressed against the shoulder portions 11 of 0, respectively. Further, a protrusion 12 is formed on the lower surface of the claw 5, and the protrusion 12 is guided into a guide groove 14 formed in the main body 13 of the coupling device. Therefore, the pawl actuating shaft 6 changes from the state shown in FIG.
When the four claws 5 are raised to the state shown in the figure, each taper 9 part is pushed by the shoulder part 11 of the enlarged part 10, and the four claws 5 move radially from the storage position in the continuous device main body 13 to the two-point tap as shown by the arrows in FIG. The claw operating shaft 6 protrudes to the iron wire position (solid line position in Figure 2).
When lowered, the pawl 5 moves towards the pawl operating shaft 6 as shown by the solid line in Figure 3.
They are attracted to each other by a spring 8 and move toward the axis of the axis. A protrusion 15 is provided in the middle part of the pawl actuating shaft 6, and a spring 17 is provided between the protrusion 15 and the stepped portion of the hole 16 formed in the connecting device body turtle 3, and the spring 17 causes the pawl to actuate. The shaft 6 is biased downward so that the tip of the enlarged part 0 protrudes from the lower surface of the coupling device main body 13.The shaft 6 is biased by a spring 19 toward the center of the coupling device main body 13. When the tip of the pin is inserted into the hole 201 provided in the pawl actuating shaft 6 as shown in FIG. It has become so.

Further, the pin 18 is pulled outward by a element 21 so that the tip can be maintained in a position where it does not engage with the hole 20 of the pawl actuating shaft 6. 22 is a connecting element for guiding the connecting device.

Next, to explain the operation, a diver brings the connecting device transfer element 22 to the mother ship side through the connecting hardware 4 of the floating object 3 on the ocean.

Next, the connecting device 1 is inserted between the connected metal objects 4 by pulling the connecting device lifting element 22 from the mother ship, and the tip of the enlarged portion 10 at the bottom of the claw actuating shaft touches the floating object 3 on the ocean as shown in FIG. Try to come into contact with them. Next, by using the weight of the coupling device 1 or by pulling the guiding element 22, the claw actuating shaft 6 whose tip is in contact with the floating object 3 on the ocean is raised into the coupling device main body 13 against the spring 17 as shown in FIG. . As a result, the protrusion 12 on the lower surface of the pawl 5 is guided by the guide groove 14, and as the pawl actuating shaft 6 rises, the pawl 5 is pushed against the shoulder 11 of the ampulla 10 via the taper 9, and protrudes radially outward as shown by the arrow. do. On the other hand, when the claw actuating shaft 6 rises within the coupling device main body 13 and the tension on the element 21 is released, the tip of the pin 18 engages with the hole 201 to maintain the raised state of the claw actuating shaft 6. The protruding state of is also maintained. Next, when the hanging rope 2 is lifted in this state, the claw 5 engages with the connected hardware 4, the coupling device 1 and the offshore floating object 3 are connected, and the floating object 3 is hoisted and recovered. . Next, when landing on water, pull the element 21 and release the claw actuating shaft 6.
When the pin 18 is disengaged, the pawl operating shaft 6 is lowered by the spring force of the spring 17. At the same time, the spring 8 causes each pawl 5 to
Since it is pulled back to the solid line position in the figure and stored in the coupling device main body 13, the engagement between the claw 5 and the metal object 4 to be coupled is released, and the offshore floating object 3 is released from the coupling device 1. Note that the number of claws 5 is not limited to four as shown in the drawings. As explained in detail above, the present invention has the advantage of applying the tip of the claw actuating shaft, which is attached to the tip of the hanging element and protruding downward from the connecting device main body, to the object to be connected, and at the same time, the claw actuating shaft is moved under the weight of the connecting device main body. Alternatively, the object to be connected and the main body of the connecting device can be connected by pulling the main body of the device downward and retracting it into the main body of the device, and engaging the claw with the connected portion village. , even if the object to be connected is a floating object on the ocean, there is no need for the diver to directly hold a large connecting metal fitting to connect it, and it is possible to connect or release the object without touching the main body of the connecting device. It is extremely safe because it can do this, and there is no need for a special power source for this purpose.

The present invention can be applied to a submersible, a device for landing and retrieving underwater objects, a device for hoisting heavy objects on land, and the like.
