In this embodiment, the urging member 7 has a return urging force enough to lift the base 1 when the moving body 8 is suspended by the suspending means 6. Therefore, when the movable body 8 is suspended by the suspending means 6, when the suspended object 4 having a predetermined load stronger than the urging force of the urging body 7 is suspended on the hook body 3, the movable body 8 is moved relative to the base 1. The hanging object 4 is moved upward as much as possible, and is configured to move downward with respect to the base 1 only when the load on the hook body 3 is removed from the suspended state.

The operation of the switching mechanism for switching the hook body 3 having the above-described configuration according to the present embodiment between the suspendable state and the suspendable state will be described.

First, when the moving body 8 is moved upward with respect to the base 1, the guide plate 24 of the rotation preventing portion 9 is fitted into the stepped recess 3b of the hook body 3 as shown in FIG. In this state, the rotation of the hook body 3 is prevented (at this time, the locking claw body 11 relating to the rotation preventing section 5 is pushed up by the release section 23 and detaches from the locking section 3a). When the hook 8 is moved upward, as shown in FIG. 10, the moving member 14a of the hanging rotation preventing portion 14 is brought into contact with the contact support surface 3c of the hook body 3.
(At this time, the guide plate 24 related to the rotation preventing portion 5 is separated from the stepped concave portion 3b of the hook body 3.)
In this state, the suspended object 4 can be moved while being suspended.

Thereafter, the suspended object 4 is placed on the placing portion 29 and the moving body 8 is lowered downward so that no load is applied.
a is separated from the contact support surface 3c of the hook body 3, and
The guide plate 24 according to the rotation preventing portion 9 shown in FIG.
Is fitted in the step-shaped concave portion 3b, and
By moving the moving body 8 further downward, the guide plate 24 slides for a while while coming into contact with the stepped concave portion 3b of the hook body 3 as shown in FIG. The urging member 2 is rotated by the return urging force.

As described above, the switching mechanism of the hook body 3 according to the present embodiment is such that the moving member 14 moves within the upper predetermined range W (see FIG. 12) of the range in which the moving body 8 (moving member 14) moves. In this case, the rotation preventing portion 9 and the hanging-time rotation preventing portion 14 are in contact with the hook body 3 when the hook 3 is in operation.
The moving member 14a is configured to come into contact with the hook body 3 when the moving body 8 is moved to the uppermost portion of the upper predetermined range W, and when the moving member 14a is not in contact with the hook body 3, When the movable body 8 moves within the upper predetermined range W, the guide plate 24 comes into contact with the hook body 3, and the guide plate 24 according to the rotation preventing portion 9 and the hanging rotation preventing portion 14 While the moving member 14a is in contact with the hook body 3, the rotation of the hook body 3 is prevented,
When moving in the other range, the hook body 3 can return and rotate by the urging of the urging body 2.

Further, in this embodiment, even after the rotation blocking state of the hook body 3 in the rotation blocking section 9 is released by moving the moving body 8 downward on the base 1, the rotation blocking section 9 is not moved. Instead, there is provided a rotation preventing portion 15 at the end of suspension for preventing the rotation of the hook body 3.

At the end of the suspension, the rotation preventing portion 15 is
As shown in FIGS. 3 and 14, a locking member 17 which is made of an appropriate metal member and is rotatable by being biased by the biasing body 16 against the base 1.
It is constructed by pivoting.

The locking body 17 is normally prevented from being biased and rotated by the pin rod 27, and when the pin rod 27 is removed, the locking body 17 is rotated by the biasing force of the biasing body 16 and provided on the hook body 3. Locking part 3
It is configured such that the hook body 3 can be prevented from rotating by being locked to a.

May be.

When the suspension is completed, the rotation preventing portion 15 is provided with the locking member 17 for the hook 3 only when the rotation preventing state of the hook 3 in the rotation preventing portion 9 is completely released.
When the hook is released, the hook body 3 is configured to return and rotate. That is, during the suspension, even if the release means 18 is operated, the rotation prevention state of the hook body 3 is not released, of course. Even when the suspension is completed, if the guide plate 24 related to the rotation preventing portion 9 is in contact with the hook body 3, the return rotation of the hook body 3 does not occur even if the release means 18 is operated. In other words, when the suspension of the rotation of the hook body 3 in the rotation prevention unit 15 is terminated, the suspended hanging object 4 is grounded to the mounting unit 29 and the rotation of the hook body 3 in the rotation prevention unit 9 is stopped. For the first time after the movement inhibition state is released, the operator can manually operate the release means 18 by operating the release means 18.

Hereinafter, a method of moving the suspended object 4 (the member 22A to be moved) using the hanging hook device according to the present embodiment will be described.

First, the hook body 3 is rotated against the urging body 2 so that the hanging object 4 can be suspended from the hook body 3, and the hook body 3 is rotated by the pre-hanging rotation preventing portion 5. Then, in this state, the hanging object 4 is pushed into the hook body 3 by pushing the opening / closing body 21 and hooked (see FIGS. 3 and 4).

Consequently, for example, the work efficiency in the continuous moving operation of the suspended object 4 is dramatically improved, and this operation can be performed safely. The rotation preventing portion 14 does not come into contact with the hook 3 only when the moving body 8 is moved to the uppermost position with respect to the base 1, but within the upper predetermined range W of the moving range of the moving body 8. When the moving body 8 is moving Since it is configured to abut on the hook body 3, for example, even if the suspended object 4 in the suspended state is shaken and lifted by the wind or some impact, the suspended object 4 suddenly comes off from the hanging portion 3. Will be reliably prevented and will be extremely safe,
Moreover, the hook body 3 in the rotation preventing portion 9 and the hanging rotation preventing portion 14 can be obtained by simply attaching the suspended object 4 to the mounting portion 29 and moving the moving body 8 downward in the predetermined upper range W for a while.
Can be released, so that the hanging object 4 can be quickly and satisfactorily and automatically removed from the hook body 3, so that a better operation can be performed.

In this embodiment, the hook body 3 is
The locking claw 11 of the pre-suspension rotation preventing portion 5 is rotated by the urging of the urging member 10 and is locked by the locking portion 3 a provided on the hook body 3. Therefore, it is possible to easily maintain the state in which the hook body 3 can be suspended, and thus, it is possible to perform more favorable work.

Further, in this embodiment, the rotation-prevented state is reliably released by avoiding pushing the pre-suspension rotation-prevention part 5 which is preventing the rotation of the hook body 3 by the release part 23 provided on the moving body 8. Then, instead of the pre-suspension rotation prevention portion 5, the rotation prevention portion 9 can abut on the hook body 3 to prevent the rotation of the hook body 3, so that the hook body 3 can be prevented from rotating.
The switching operation from the pre-suspension rotation prevention unit 5 to achieve the rotation prevention state to the rotation prevention unit 9 and the suspension-time rotation prevention unit 14 can be performed very efficiently, quickly, and satisfactorily.

Further, in this embodiment, the hook body is replaced with the hook body 9 even after the contact of the rotation blocker 9 with the hook 3 is released by the rotation blocker 15 at the end of the suspension. 3
A locking means 17 which can prevent the rotation of the hook body 3 by contacting the hook body 3 and release the locking of the locking body 17 constituting the rotation preventing portion 9 to the hook body 3. The operator can manually remove the hanging object 4 from the hook body 3 at will, for example, and the releasing means 18 can be turned at the end of the hanging operation as well as during the hanging of the hanging object 4. If the operation is performed only when the rotation blocking state to the hook body 3 in the motion blocking unit 9 is released, the rotation blocking state to the hook body 3 is released, and therefore,
Even better (safe) work can be performed.
