BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slinging work auxiliary tool used for artificially and supplementarily controlling the hanging state of a suspended object in slinging work.

[0002]

2. Description of the Related Art A conventional auxiliary tool 11 of this kind is shown in FIG.
As shown in FIG. 2, a generally S-shaped hook, in which a substantially S-shaped hook 13 is fixed to the tip of the rod-shaped operating body 12, is known.

If such an assisting tool 11 is used,
As shown in FIG. 8, the operator operates the proximal end grip portion 12 of the operating body 12.
By holding the hook 13 on the wire 7 extending from the suspended object 5 to the hook 6 by holding a, the suspended state of the suspended object 5 during the slinging work is artificially controlled (for example, the suspended object 5 is large. To prevent it from swinging,
It is possible to guide the suspended object 5 so as to accurately move it to a desired position.

[0004]

However, in the above-mentioned conventional auxiliary tool 11, the two bodies 12 and 13 are integrated, and the swing of the suspended object 5 and the vibration of the wire 7 on which the hook 13 is hooked can be manipulated. Since the power is directly transmitted to the hand holding the body 12, there is a risk that the worker may be swung or the wrist may be injured (for example, sprained) during the above control work, resulting in an extremely heavy labor burden.

Moreover, when the suspended object 5 is a large object such as a long object (see FIGS. 4 and 5), the hook 7 is hooked on the wire 7 because the distance to the wire 7 is long. Becomes physically difficult. Therefore, it is often useless in slinging work in recent years when the suspended object 5 tends to be large. Further, in such a case, the hook 13 is connected to the wire 7
Even if it can be hooked on, the worker will approach the suspended object 5, so there is a risk of touching the suspended object 5. As a countermeasure against such a case, it may be possible to make the operating body 12 longer.
If the operating body 12 is made longer than necessary, not only the control work cannot be performed well, but also the labor burden is large and it is dangerous, so that it cannot be adopted at all. Depending on the shape of the suspended object 5 or the hanging condition of the wire 7, it may be preferable to hook the hook 13 on the suspended object 5, but even in such a case, depending on the shape of the suspended object 5, In some cases, the hook body 5 cannot be hooked at an appropriate place for performing control work.

The present invention has been made in view of the above point, and provides a slinging work aid capable of safely and easily controlling the suspended state of a suspended object regardless of its shape and size. The purpose is to do.

[0007]

In the slinging auxiliary tool of the present invention, which solves this problem, an adsorbent capable of adsorbing to the surface of a suspended object is attached to the tip of a rod-shaped operating body through a universal joint. Are connected together.

[0008]

The operator holds the base end portion of the operating body and adsorbs the adsorbent onto the surface of the suspended object, whereby the suspended state of the suspended object can be artificially controlled. At this time, the adsorbent can be adhered to the optimum place for performing the control work. Therefore, regardless of the shape and size of the object to be hung, the worker does not approach the object to be hung for a certain amount or more, and can safely and satisfactorily perform the control work in the hanging state.

Moreover, since the suction body and the operating body are connected by the universal joint, the vibration and shaking of the suspended object are absorbed and relaxed at the universal joint portion and are not directly transmitted to the hand holding the operating body. Therefore, there is no risk that the worker will be swung around or the wrist will be damaged, and in combination with the fact that the adsorbent can be bonded to the optimum place for performing the control work as described above, the control work can be performed. It can be performed easily with less labor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to the embodiments shown in FIGS.

As shown in FIG. 1, the auxiliary tool 1 of this embodiment comprises an operating body 2 and an adsorbing body 3 which are connected via a universal joint 4.

As shown in FIG. 1, the operating body 2 is a rod-shaped body having an appropriate length formed by bending the base end portion into a substantially U-shape to form a handle portion 2a.

As shown in FIGS. 1 to 3, the adsorbent 3 is composed of a disk-shaped or annular permanent magnet 3a and a bottomed cylindrical metal holder 3b for holding the magnet 3a. Of course, the permanent magnet 3a and the holder 3b are firmly bonded and integrated with a bolt or the like.

The universal joint 4 connecting the suction body 3 to the tip of the operating body 2 has a holder 3b as shown in FIGS.
First connecting piece 4a projecting from the center of the side end surface of the body, second connecting piece 4b fixed to the tip of the operating body 2, and both connecting pieces 4
and a third connecting piece 4c for connecting between a and 4b.
The connecting piece 4a and one end of the third connecting piece 4c are pivotally connected to each other by a first pin 4d parallel to the side end surface of the holder 3b so as to be relatively rotatable, and the second connecting piece 4b and the third connecting piece 4c are connected to each other. The end portion is pivotally connected to the first pin 4d so as to be relatively rotatable by a second pin 4e orthogonal to the first pin 4d.

According to the auxiliary tool 1 configured as described above, the operator holds the grip portion 2a of the operating body 2 and holds the suction body 3
It is possible to artificially control the suspended state of the suspended object 5 by adsorbing the attracting action surface 3c, which is the magnet exposed surface, to the appropriate place on the surface of the suspended object 5.

Therefore, even if the object to be hung 5 is large as shown in FIG. 4 or 5, and even if the distance from the object to be hung 5 to the wire 7 extending to the hook 6 is long, the operator hangs the object. It is possible to safely and satisfactorily control the suspended state without approaching the object 5.

In addition, in such control work, since the operating body 5 can freely move up and down, left and right with respect to the suction body 3 by the universal joint 4, vibration or shaking of the suspended object 5 can be held by the hand holding the operating body 5. Is not directly transmitted to, but is absorbed and relaxed to some extent in the connecting portion 4 of the two bodies 2 and 3.
Therefore, the control work can be performed safely and easily without the worker being swung or injured his / her wrist due to the vibration or shaking of the hanging object 5.

Further, the adsorption body 3 can be easily removed from the suspended object 5 by making the operating body 2 substantially parallel to the adsorption surface 3c and pulling the adsorption body 3 along the surface of the suspended object 5. It can be carried out.

The above-mentioned auxiliary tool 1 can also be used when picking up tools or the like from a place where it is difficult to reach or where it is dangerous to put one's hands directly. It's a convenient thing to use.

By the way, the structure of the present invention is not limited to the above-mentioned embodiment, and can be appropriately improved and changed without departing from the basic idea of the present invention.

For example, an electromagnet may be used in place of the permanent magnet 3a, and a hand switch installed on the handle portion 2a of the operating body 2 may be used for excitation and demagnetization operations.

The shape of the suction acting surface 3c is arbitrary, and can be appropriately devised according to the surface shape of the suspended object 6. For example, when the suction acting surface 3c is formed in a substantially V-shaped groove as shown in FIG. 6, the surface of the suspended object 6 is a curved surface (when the suspended object 6 is a pipe material or the like).
Also, it can be favorably adsorbed.

Further, as the suction means, it is also possible to adopt a suction means that uses a vacuum suction force instead of a magnetic force. For example, the suction body 3 may be provided with a suction port that can be brought into close contact with the surface of the suspended object 5 and connected to a vacuum suction pump so that the suction body 3 is sucked onto the suspended body 5 by a vacuum suction force. By doing so, even if the suspended object 5 is made of a non-magnetic material, the suspended state can be well controlled.

[0024]

As is apparent from the above description, according to the assisting tool of the present invention, the suspended state can be safely and easily controlled regardless of the shape and size of the suspended object.
