Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dunnage with a sling wire that can be used as a sling wire for lifting a suspended load such as a long steel material and as a dunnage to be laid on the floor for placing a suspended load.

[0002]

[Prior Art]

 For example, in the case of lifting long steel materials, ring wire ropes with both ends connected by connecting metal fittings are widely used as sling wires, and square steel pipes are used as dunnage to be placed on the floor to place suspended loads. Conventionally, a dunnage which also serves as a sling wire is shown in FIGS. 10 to 12 (see Japanese Utility Model Laid-Open No. 58-166576). In this dunnage 1, a central square pipe 3 in which a wire rope 2 is passed and reinforcing pipes 4 and 4 on both left and right sides, which are longer than the central square pipe 3, are integrally welded to form a rod 5, and the central square pipe 3 is also formed. The positions of the edges 3a and 3b on the upper and lower surfaces are made different so that openings 6 and 7 at different positions are formed above and below the outer portions of both ends of the central square pipe 3, and the wires 6 and 7 are formed from these openings 6 and 7. The rope 2 is pulled out. Reinforcing plates 8 and 9 are provided at the end edges 3a and 3b, and a bolt 11 is used to prevent the load from rolling down when the load is placed on the floor at the end of the reinforcing pipe 4. It is detachably attached. This dunnage 1 is used for lifting a load 12 such as a long steel material as shown in FIG. That is, the wire rope 2 is lifted while hitting the bottom corners of the load 12. In this case, since the positions of the openings 6 and 7 above and below the end of the rod 5 are different, even if the width of the load is changed, the load can be used upside down if the load is within a certain range. It is possible to cope with the difference in width.

[0003]

[Problems to be solved by the device]

 However, with the lifting method in which the wire rope 2 hits both corners of the bottom surface of the load 12 as described above, although the load width can be dealt with to some extent, the applicable range is narrow, and However, there are restrictions depending on the type of suspended load, such as the difference in the suspended load of goods and the difference between individual items and binding. On the other hand, if the wire rope is attempted to be lifted without hitting both corners of the bottom of the load so as not to be limited by the type and width (minimum width) of the load, the wire rope will not reach both ends of the central square pipe 3. There is a risk that the wire rope may be broken by directly hitting the edges 3a and 3b and sharply bending.

The present invention has been made in view of the above circumstances, and it is possible to lift an arbitrary suspended load without being restricted by the type and width of the suspended load, and at the same time, a sling wire without damage to the wire rope. The purpose is to provide dunnage with.

[0005]

[Means for Solving the Problems]

 The dunnage with sling wires according to the present invention, which solves the above-mentioned problems, is a wire rope protector having a rectangular cross-section tube as a dunnage and through-holes in the tube longitudinal direction that are fitted to both ends of the tube. And an annular wire rope that is inserted into the pipe body through the through holes of the left and right wire rope protectors and that has both ends connected to each other by connecting metal fittings outside the pipe body.

According to a second aspect of the present invention, a taper surface or a curved surface for forming a gentle curve of the wire rope is formed at the through hole exit portion of the outer end surface in the longitudinal direction of the tubular body of the wire rope protector. ..

A third aspect of the invention is characterized in that the wire rope protector has a split structure.

A fourth aspect of the present invention is characterized in that a connecting fitting with a magnet, which is integrally fixed with a magnet, is used as the connecting fitting.

[0009]

[Action]

 In the above configuration, since the wire rope does not lift the suspended load by hitting both corners of the bottom of the suspended load, but the pipe body carrying the suspended load is suspended, the type and width of the suspended load (especially the minimum width) There are few restrictions due to, and it can be used to lift any suspended load.

Since the wire rope does not directly contact both end edges of the tubular body but hits the wire rope protector and gently bends along the tapered surface or the curved surface of the wire rope protector, there is no risk of damage to the wire rope.

Further, in the structure in which the wire rope protector is divided into two parts, the wire rope can be easily inserted into or removed from the through hole of the wire rope protector, so that the wire rope can be easily detached from the tube body. It is possible and can be used as a dunnage or sling wire, respectively, which is convenient for use.

When a connecting fitting with a magnet is used as the connecting fitting, when the suspended load of steel material is piled up in the storage area, the connecting bracket is fixed to the suspended load by the magnet adsorbed to the suspended load. Displacement is prevented.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall perspective view of a dunnage 20 with sling wires according to an embodiment of the present invention. The dunnage 20 with sling wires is, for example, a tube body 21 using a square steel tube having a length of □ 3.2 × 50 × 50 and a length of 1300 mm, and fitted in both ends of the tube body 21 in the longitudinal direction of the tube body. The wire rope protector 22 having a through hole 22a is inserted into the pipe body 21 through the through holes 22a of the left and right wire rope protectors 22, and both ends of the pipe body 21 are connected to each other in an annular shape by the connecting metal fittings 23 outside the pipe body 21. And a wire rope 24.

As shown in FIGS. 2 and 3, the wire rope protector 22 has a gentle curve for the wire rope 24 to be pulled out to the exit portion of the through hole 22a on the outer end face in the longitudinal direction of the tubular body. Forming a tapered surface 22b. The wire rope protector 22 in the illustrated example is made of, for example, a piece of oak wood, and has a two-piece structure composed of two pieces 22c 1 and 22c 2. Details of each divided piece 22c divided into two are shown in FIGS. As shown in the drawing, each of the divided pieces 22c has a wedge-shaped inclined surface on the left and right sides so that the divided pieces 22c can be fitted tightly inside the tube body 21. The through hole 22a is formed by the semicircular groove 22d provided at the center of the contact surface of each divided piece 22c. Further, each divided piece 22c has the above-mentioned tapered surface 22b. The wire rope protector 22 is fixed to the tube body 21 by driving a nail 27 into the tube body 21 through a nailing hole 21a.

The connecting fitting 23 has a structure in which a slip-off prevention spring 23b is attached to the opening of the C hook 23a so as to be openable and closable, and a magnet 23c is attached to the rear surface of the C hook 23a. In the wire rope 24, the loops 24a at both ends are inserted into the C hooks 23a in such a manner that the retaining springs 23b of the connecting fittings 23 are pushed into each other and the both ends are connected to each other to form an annular wire rope.

The usage state of the above dunnage 20 with sling wires is shown in FIGS. 7 and 8. In the illustrated example, three bundles 30 of round steel pipes are placed on the tubular body 21 of the dunnage 20 with sling wires laid side by side in parallel, and the wire rope 24 is surrounded by the connecting metal fittings 23 so as to surround these bundles. It is connected in a ring. When the wire rope 24 of the dunnage 20 with sling wires set in this way is lifted using the three bundles of the bound steel pipes 30 shown in the figure as a unit of load, the wire rope 24 is attached to both corners of the bottom of the load 30. Instead of hoisting the hanging load, the pipe body 21 carrying the hanging load 30 is hoisted. Therefore, there are few restrictions depending on the type and width of the suspended load 30 (here, there is a maximum width limitation, so here the minimum width). Further, since the wire rope 24 does not directly contact both end edges of the tube body 21 but hits the wire rope protector 22 and gently bends along the taper surface 22b thereof, there is no risk of damage to the wire rope 24.

Further, as shown in FIGS. 7 and 8, the pipe 21 receives the suspended load even when it is stacked in a high level, for example, four-tiered stacking. Even if the bottom of the load is uneven, it is stable, and it is possible to stack the load in the storage area at a high level.

Further, since the wire rope protector 22 has a split structure, the wire rope 24 can be easily inserted into or removed from the through hole 22 a of the wire rope protector 22. Therefore, the wire rope 24 can be easily attached to and detached from the tubular body 21, and each can be used as an independent dunnage or sling wire, which is convenient in use.

Further, since the connecting fitting 23 is provided with the magnet 23c, when the hanging load is placed in the storage area, the magnet 23c can be adsorbed to the hanging load to fix the connecting fitting 23 to the hanging load. Therefore, the displacement of the tubular body 21 as the dunnage is prevented.

Note that the types of the suspended loads to be targeted are not limited to the round steel pipes in the illustrated example, but the steel sheet pile 31 shown in FIG. 9 or a wide deck plate (not shown) and other various suspended loads. It can be applied to both a bundled load and a loose load, and the number of bundles as a suspended load unit in the case of a bundled load is arbitrary.

As the material of the tube body 21, an aluminum alloy or the like can be used as appropriate according to the weight of the suspended load. In addition, a cloth tape or the like may be attached to the upper and lower surfaces of the tube body 21 to prevent slippage or damage. Further, the wire rope protector 22 is not limited to wood, and plastic or hard rubber or the like may be used.

[0022]

[Effect of the device]

 According to the present invention, since the wire rope does not hit the two corners of the bottom of the suspended load to suspend the suspended load, but the pipe carrying the suspended load is suspended, the type and width of the suspended load (minimum width) There are few restrictions due to, and it can be used to lift any suspended load.

Since the wire rope does not directly contact both end edges of the pipe body but contacts the wire rope protector and gently bends along the taper surface of the wire rope protector, there is no risk of damage to the wire rope.

Stacking a simple annular wire rope while hanging it on a suspended load is unstable when the bottom of the suspended load is uneven. It is stable even with irregularities, and can be highly loaded in the storage area for suspended loads.

Since the wire rope can be handled integrally with the tubular body as the dunnage, it is convenient for recovery and maintenance.

Further, in the structure in which the wire rope protector is divided into two parts, the wire rope can be easily inserted into or removed from the through hole of the wire rope protector, so that the wire rope can be easily detached from the tube body. It is possible and can be used as a dunnage or sling wire, respectively, which is convenient for use.

When the connecting fitting with magnet is used as the connecting fitting, the connecting fitting can be fixed to the suspended load by the magnet adsorbed to the suspended load when the suspended load of steel materials is stacked. This can prevent the displacement of the tubular body as the dunnage.
