Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hanging hook used when a heavy object such as a concrete block is hung by a crane or the like for installation.

[0002]

[Prior art]

 When suspending such a heavy object, usually, the hanging member provided on the heavy object and the hanging hook are connected directly or through a slinging wire or the like, and after the heavy object is lowered to a predetermined position, the suspension is suspended. The hooks and slinging wires are manually removed from the heavy metal hanging bracket to separate the hanging hook from the heavy weight. However, in places where manual work is difficult, such as when placing concrete blocks on the sea floor or hanging heavy objects at high altitudes, the hooks can be separated from heavy objects by remote control. Work is required.

FIG. 1 shows an example of a hanging hook that enables such a separating operation by remote operation. In FIG. 1, a suspension hook 10 suspended from a tip of a crane 2 of a hoist ship 1 by a suspension wire 3 is connected via a shackle 13 and a ring 14 connected to the suspension wire 3 via a main body 11 and a ring 12. A seho-slip 15 provided rotatably and a tightening ring 16 for preventing rotation of the seho-slip 15, and a shackle 19 attached to a hanging bracket 18 provided on the upper surface of a heavy object 17 is passed through the A heavy load 17 is suspended. Also, a messenger wire 20 lowered from the tip of the crane 2 is connected to the tip of the tightening ring 16.

FIG. 2 is a diagram showing a procedure for releasing the hanging hook 10. First, in the state shown in FIG. 2 (a), the senho slip 15 passing through the shackle 19 cannot be rotated by the fastening ring 16 fitted. Here, assuming that the heavy object 17 is lowered on the ground or the seabed, the hanging wire 3 is wound down in the state shown in FIG. At the same time, the messenger wire 20 connected to the tip of the fastening ring 16 is pulled up. Then, as shown in FIG. 2 (b), the sensing slip 15 comes off the fastening ring 16 and rotates downward (counterclockwise). Thereafter, as shown in FIG. 2 (c), when the hanging wire 3 is wound up and the hanging hook is raised, the sensor slip 15 comes off the shackle 19. Thereby, the heavy load 17 of the hanging hook 10 is released.

However, in the hanging hook 10, it is necessary to strongly tighten the tightening ring 16 to the sensor hook 15 in order to prevent the sensor hose 15 from coming off the shackle 19. Also, conversely, when removing the sensor hose 15, it is necessary to wind the messenger wire 20 with a strong force. Therefore, if the tension of the messenger wire 20 at the time of removal is not sufficient, it is necessary for an operator to loosen the fastening by hitting the fastening ring 16 with a hammer or the like. Further, in the illustrated example, when a shackle wire is used instead of the shackle 19, there is a problem that the shackle wire cannot be collected after the heavy object 17 is opened.
