Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a sling wire used for lifting materials such as a long object and a lump, and various equipment with a plurality of wires.

[0002]

[Prior Art]

 Conventionally, when hoisting the above-mentioned materials and equipment, a plurality of wires such as two wires, three wires, or four wires are used, and one end of each wire is hooked on the crane and the other end is hooked. I hang it on materials and equipment.

[0003]

[Problems to be solved by the device]

 However, when performing slinging work as described above, in general, in general, a plurality of wires are often intertwined with each other, and the entanglement of the wires must be unraveled prior to slinging work. There was a drawback that workability deteriorated.

[0004] Furthermore, if the slings are slung without fully untangling them and they are unexpectedly suspended, the weight of the materials and equipment does not act evenly on the wires, and the suspension posture of the materials and equipment is unstable. However, there were drawbacks such as lack of safety in that the materials and equipment rotate due to hanging.

In order to prevent the above-mentioned entanglement, therefore, as shown in the front view of FIG. 4, a long steel material 01 is connected to a wire 03 to be hooked on a hook 02 of a crane, and Although there is a so-called traverser in which wires 04, 04 for slinging are connected at intervals in the longitudinal direction, there is a drawback that it is difficult to handle because of its large weight.

Further, in the case of the traverser, when the material to be lifted and the shape of the equipment are constant, there is an advantage that the sling wires 04, 04 can be hung parallel to each other. Depending on the sling position of the wires 04, 04 on the material 05, as shown in FIG. 4, the distance L1 between the sling positions of the wires 04, 04 on the material 05 is the connection of the sling wires 04, 04 to the steel material 01. It becomes smaller than the interval L2, and the weight of the material 05 acts to exert a bending stress on the steel material 01, so that the steel material 01 is bent and deformed. For a lump having a width smaller than the connection distance L2 between the sling wires 04, 04, the weight of the material 05 always acts so as to exert a bending stress on the steel material 01, which makes it unsuitable for general use. There was a flaw that was lacking.

The present invention has been made in view of the above circumstances, and can prevent entanglement of a plurality of wires to efficiently perform slinging work and improve safety and versatility. The purpose is to do so.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the sling wire of the present invention suspends and supports an anti-entanglement ring from at least one wire of a plurality of wires, and the anti-entanglement ring supports each wire with respect to each other. A partitioning material that prevents access is provided, and each wire is individually passed through and an annular portion that allows movement within a predetermined range is formed.

[0009]

[Action]

 According to the configuration of the sling wire of the present invention, during slinging work, by lifting the upper ends of the plurality of wires, the respective wires are passed through the individual annular portions formed in the entanglement prevention ring and are separated from each other by the partition member. It is possible to suspend materials and equipment with each wire in a state where the approach of the wire is blocked.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings.

(First Embodiment) FIG. 1 is a perspective view showing a first embodiment of a sling wire according to the present invention. Each of the two wires 2, 2 hung on the hook 1 of the crane is shown in FIG. An entanglement prevention ring 4 is suspended and supported on the annular hanging portion 2a through a number wire 3 to form a sling wire.

In the entanglement prevention ring 4, two pipe partition members 4b, 4b are integrally connected to a pipe 4a bent into a track shape by welding, and the arc portion of the pipe 4a and the partition members 4b, 4b are respectively connected. By forming a circular portion 4c which allows the wire 2 to pass through and allows movement within a predetermined range, and an arc pipe 4d for connecting the number wire 3 is integrally connected by welding to the corresponding upper portions of the partition members 4b, 4b. It is composed of

With the above configuration, the two hanging wires 2 and 2 are separated by the partition members 4b and 4b by lifting the annular hanging portion 2a during slinging work, and the lower ends of the wires 2 and 2 are made of material. 5 and equipment can be slung and the material 5 and equipment can be hung in a well-balanced manner.

Second Embodiment FIG. 2 is a perspective view showing a entanglement prevention ring of a second embodiment of the sling wire according to the present invention. The difference from the first embodiment is as follows. That is, three pipe partition members 14b ... Are integrally connected by welding to a pipe 14a bent into a three-leaf shape, and the wires 2 are individually connected by the arc portions of each of the pipes 14a ... And the partition members 14b. An annular portion 14c is formed which allows the wire to pass through and a predetermined range of movement, and an arc pipe 14d for connecting a numbering line (not shown) is integrally connected by welding to upper portions of the partition members 14b ... The entanglement prevention ring 14 of the sling wire of the type that uses the wire 2 of the book is configured. Although not shown, the connecting structure between the wires 2 and the numbered lines 3 and the connecting structure between the numbered lines 3 and the arc pipes 14d are the same as those in the first embodiment.

(Third Embodiment) FIG. 3 is a perspective view showing a entanglement prevention ring of a second embodiment of the sling wire according to the present invention. The difference from the first embodiment is as follows. That is, two pipes 24a, 24a bent and formed in a track shape are overlapped with each other in a cross shape and integrally connected by welding, and parallel intermediate portions 24b of the upper and lower pipes 24a, 24a are formed as a partition member. The circular portions 24a and 24a and the intermediate portion 24b serving as a partitioning member form an annular portion 24c which allows the wire 2 to pass individually and allows movement within a predetermined range, and in the lower pipe 24a. An arc pipe 24d for connecting a numbering wire (not shown) is integrally connected by welding to the upper pipe 24a at a position corresponding to the upper portion of each of the intermediate portions 24b, 24b as the partition member, and the four wires 2 ...

In the above embodiment, each of the entanglement prevention rings 4, 14 and 24 is made of a pipe so that the weight can be made lighter. However, instead of the pipe, a light material such as round steel may be used.

Further, in the above embodiment, the entanglement prevention rings 4, 14 and 24 are hung and supported by the two or three wire lines 3 so as to easily maintain the predetermined horizontal posture. As a device, it may be configured so as to be suspended and supported by one wire 3.

[Effect of the device]

 As described above, according to the sling wire of the present invention, when slinging work, it is possible to hang up the upper ends of a plurality of wires without causing the wires to come close to each other. It can be easily prevented and the slinging work can be performed efficiently.

In addition, since it is possible to prevent the wires from being entangled with each other, it is possible to prevent the materials from rotating when the materials are suspended. Further, since the wires are allowed to move within a predetermined range within the annular portion, the materials and the equipment can be prevented. The weight of the wire can be applied to the wire evenly, and it is possible to avoid the bending stress acting on the steel material as in the conventional traverser to cause bending deformation, and the wire can be satisfactorily adjusted according to the size of the material. It can be hung on materials, improving safety and versatility.
