[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is for slinging work that is used to artificially and auxiliary control the hanging posture of a suspended object when slinging a suspended object having plate-like ends such as plate materials and channel materials. It concerns auxiliary equipment.

[0002]

[Prior Art]

 As a conventional auxiliary tool 21 of this type, as shown in FIG. 5, what is generally called a hand hook, in which a substantially S-shaped hook 21b is fixed to the tip of a metal rod 21a, is known.

If such a hook 21 is used, an operator holds the handle 21c of the hook 21 and hooks the hook 21b on the wire 23, as shown in FIG. It is possible to artificially control the suspension posture of the object 22 (for example, to prevent the object 22 from swinging largely, or to guide the object 22 to move accurately to a desired position).

[0004]

[Problems to be solved by the device]

 However, since the whole of the above-mentioned hand hook 21 is a rigid body, the shaking of the object to be hung 22 and the vibration of the wire 23 hooked on the hook 21a are directly transmitted to the hand, so that the worker is swayed during the control work. However, there is a risk that the wrist may be injured (for example, sprained) and the labor burden is extremely large. Further, since the length of the hook 21 that can be handled by the operator is limited, when the object 22 to be hung is large, the operator must approach the object 22 to be hung. It's very dangerous. As a countermeasure against such a case, it has been attempted to tie a rope to the object to be hung 22 and control the hanging posture by this rope, but the work of tying the rope to the object to be hung 22 is troublesome and troublesome. Not only that, depending on the shape of the object 22 to be suspended, the rope cannot be bound securely, which causes a problem in workability.

It is an object of the present invention to provide a slinging auxiliary tool capable of safely and easily controlling the hanging posture of a suspended object without causing the above problems.

[0006]

[Means for Solving the Problems]

 An aid for slinging work according to the present invention, which has solved this problem, is an adsorbent having an adsorbing part capable of adsorbing to a plate-like end of a suspended object, and a swingable support supported by the adsorbent. The pressing body that has a pressing part that is separated from and contacted by the suction part, the operation rope that has its tip connected to this pressing body, and the operation rope that is attached to the suction body and that operates on the tip side of the operation rope. The rope guide is provided so that when the rope is pulled in an arbitrary direction, the rope tension acts so as to displace the pressing portion toward the suction portion.

[0007]

[Action]

 The suction part and the pressing part are located on both sides of the plate-shaped end of the object to be suspended, and then the suction part is sucked onto the plate-shaped end and the operation rope is pulled. And the plate-shaped end portion is pinched between the suction portion and the pressing portion. At this time, the rope tension acting on the pressing body should always displace the pressing part toward the suction part regardless of the pulling direction of the operating rope because the tip part of the operating rope is guided by the rope guide. Will work.

Therefore, by pulling the operation rope in an appropriate direction, the hanging posture of the object to be hung can be controlled via the operation rope. At this time, the operating rope does not have a length limitation for handling, such as a hand hook.Therefore, if the operating rope has an appropriate length, it can be used when the object to be hung is large. However, the worker can work in a safe position away from the suspended object.

Moreover, since the operator controls the suspended object via the operation rope, the vibration and swing of the suspended object are absorbed and alleviated by the operation rope and are not directly transmitted to the hand holding the operation rope. Therefore, there is no risk that the worker will be swung around or the wrist will be injured.

Further, in the case where the pulling direction of the operation rope is changed, even if the operation rope temporarily loosens, the auxiliary tool may come off from the plate-like end portion due to at least the suction action of the suction portion. There is no. Of course, when the pulling of the operation rope is restarted, the plate-shaped end portion is clamped by the suction portion and the pressing portion.

Therefore, coupled with the fact that the attachment / detachment of the auxiliary tool to / from the plate-shaped end portion can be performed by one-touch operation (the attachment / detachment operation to / from the plate-shaped end portion of the suction portion), the suspended posture of the suspended object can be safely It can be controlled easily.

【Example】

 Hereinafter, the configuration of the present invention will be specifically described based on the embodiments shown in FIGS.

As shown in FIGS. 1 to 3, the slinging aid 1 of this embodiment comprises a suction body 2, a pressing body 3, an operating rope 4 and a rope guide 5.

The adsorbent 2 is formed by bending a rectangular metal plate into a U-shape, and has an adsorbing part 6 and a supporting part 7 that face each other in parallel, and a connecting part 8 that connects the both parts 6 and 7. .. A magnet 6a is fixed to the attracting portion 6 in an embedded manner so that the attracting portion 6 can be attracted to the plate-like end portion 22a of the suspended object 22 by magnetic force.

The pressing body 3 is formed by bending a metal rod 9 into a substantially V shape, and has a pressing portion 10 at one end and an annular rope connecting portion 11 at the other end. The pressing portion 10 is formed by fitting and fixing a pair of rubber rollers 10b and 10b on a pin 10a which is welded to one end of the metal rod 9 in an orthogonal manner. In this pressing body 3, the pin 9a, which is welded orthogonally to the vicinity of the bent portion of the metal rod 9, is inserted into and supported by the cylindrical portions 7a, 7a formed by bending the tip of the supporting portion 7. With the pressing portion 10 located between the suction portion 6 and the support portion 7 and the rope connection portion 11 located on the outer surface side of the support portion 7 and near the connection portion 8, the suction member 2 It is swingably supported by. That is, by oscillatingly displacing the rope connecting portion 11, the pressing portion 10, that is, the rubber rollers 10b, 10b is brought into contact with and separated from the suction portion 6 (see FIG. 3). It should be noted that concave grooves are formed on the surface of each rubber roller 10b so as to be aligned in the circumferential direction so as to improve the frictional engagement force with the plate-shaped end portion 22a.

The tip of the operation rope 4 is fixed to the rope connecting portion 11 of the pressing body 3.

The rope guide 5 is a U-shaped bent metal rod, and is welded to the outer surface of the connecting portion 8 of the adsorbent 2. The operation rope 4 is inserted through the rope guide 5, and when the operation rope 4 is pulled in any direction, the tip end side portion 4a of the operation rope 4 is attracted by the rope tension T to the pressing portion 10. It is designed to guide in order to act in the direction of displacement in 6 directions (see FIGS. 2 and 3).

According to the slinging work aid 1 configured as described above, for example, as shown in FIG. 4, a large iron plate 22 as an object to be suspended is clamped at its upper end by a clamp-type suspender 24. In the case of hoisting the iron plate 22, the adsorbing part 6 of the adsorbing body 2 may be previously adsorbed to the plate-shaped end part 22a of the iron plate 22 at an appropriate position on the peripheral edge of the iron plate 22, and then the operation rope 4 is pulled to suspend the iron plate 22. The posture can be controlled safely and easily.

That is, when the operation rope 4 is pulled, the tension T for displacing the rope connecting portion 11 of the pressing body 3 in the rope guide 5 direction acts on the distal end side portion 4a of the operation rope 4 regardless of the pulling direction. The tension T rotates the pressing body 3 to press the pressing portion 10 against the plate-shaped end portion 22a. As a result, the plate-shaped end portion 22a is pinched between the suction portion 6 and the pressing portion 10, so that the auxiliary tool 1 is reliably connected to the iron plate 22 (see the solid line in FIG. 3), and the operation rope 4 is connected. By pulling, it is possible to control the suspension posture satisfactorily and safely from a position sufficiently distant from the iron plate 22 (see FIG. 4).

At this time, the pressing portion 10 and its swinging fulcrum 9a in the direction of withdrawing the plate-shaped end portion 22a from between the both portions 6 and 10 (leftward in FIG. 3) have a positional relationship as shown in FIG. Therefore, the pressing portion 10 is apt to bite into the plate-like end portion 22a in the above-mentioned withdrawal direction. Therefore, the pressing portion 10 is formed by the rubber rollers 10b and 10b having a high friction coefficient, that the rubber rollers 10b and 10b are pressed by the plate-like end portion 22a in the compressed state, and that the operating force is proportional to the pulling force of the operation rope 4. With the increase in the pressing force of the pressing portion 10 to the plate-shaped end portion 22a, the auxiliary tool 1 may come off from the plate-shaped end portion 22a while the operation rope 4 is being pulled. There is no fear. Of course, even when the pulling direction of the operation rope 4 is changed, when the operation rope 4 is loosened and the rope tension T does not act on the operation rope 4, the suction portion 6 does not have the plate-shaped end. Since it is adsorbed to the portion 22a, there is no fear that the auxiliary tool 1 will come off from the plate-shaped end portion 22a.

By the way, when the object 22 to be hung is not a plate-like object such as an iron plate, an appropriate plate-like end 22a is selected so that the adsorption part 6 is adsorbed. For example, when the object 22 to be hung is a machine part, the suction portion 6 is attached to a plate-like portion such as a bracket. As described above, the slinging assistance tool 1 according to the present invention has any shape and size as long as the plate-shaped end portion 22a capable of being pinched by the suction portion 6 and the pressing portion 10 is present. 22 can also be used satisfactorily.

The present invention is not limited to the above-described embodiments, but can be appropriately improved and modified within a range not departing from the basic idea of the present invention.

For example, the shape of the suction surface of the suction portion 6 to the plate-shaped end portion 22a is not limited to a flat shape, but may be an arc shape, an obtuse V shape, or the like. Even when the end portion 22a has a non-planar shape (for example, a curved shape), it can be adsorbed well. Further, as the suction means of the suction portion 6, a suction cup or the like that does not utilize magnetic force can be used, and in this case, it is applied even when the suspended object 22 is a non-magnetic material such as aluminum. It is convenient to get.

Further, the pressing portion 10 is composed of a rotatable roller, and the adsorbing member 2 is provided with an inclined cam plate facing the adsorbing portion 6, so that the pressing force of the pressing portion 10 is plate-shaped by the tensile force T. It may be configured to be able to bite into the end portion 22a. With this configuration, the so-called roller wedge effect allows the plate-shaped end portion 22a to move to the both ends even if the frictional force between the pressing portion 10 and the plate-shaped end portion 22a or the tension T of the operation rope 4 is not so large. It is possible to reliably clamp between 6 and 10. Moreover, once clamped, the pressing portion 10 (roller) is self-locked between the cam plate and the plate-shaped end portion 22a even if the operation rope 4 is loosened as described above. The advantage is that the clamping by both parts 6 and 10 is not released. If such a self-locking effect is exerted, even if the tensile force T does not act, the auxiliary tool 1 can be reliably detached from the plate-shaped end portion 22a without being attracted by the attracting portion 6. Since this can be prevented, the suction force of the suction portion 6 can be made as small as possible to facilitate the attachment / detachment of the auxiliary tool 1 to / from the suspended object 22.

Further, it is preferable that the pressing state of the plate-shaped end portion 22a of the pressing portion 10 is such that it is biteable in the pulling-out direction of the plate-shaped end portion 22a on the clamp as described above. Even if it is not configured as described above, a necessary and sufficient clamping force can be secured by devising the shape of the pressing portion 10 and the constituent materials. The pressing portion 10 may be biased toward the suction portion 6 by a spring or the like.
