Abstract

The present invention is used to hang on the hook formed at the four vertices of the net for moving cargo, and relates to a sling to be lifted by a crane or the like even a lot of cargo in the net. The sling of the present invention has a structure in which the edge portion of the sling is not stretched even when a large load is applied to the net, and thus, the sling has an advantage of not being easily broken due to no tension force even when the edge portion of the sling contacts a sharp object. .

According to the present invention, the upper fabric and the lower fabric is formed to be superimposed, and in the sling is combined with the upper fabric and the lower fabric is sewn stitched tightly and integrally fixed, the binding yarn is sewn on the edge portion of both ends along the longitudinal direction of the sling A net sling for moving freight is provided, which is characterized in that it is not.

Description

Net sling for moving cargo {Sling for net}

The method used to move the cargo is a method using a crane or a machine such as a forklift. In the case of using a crane, a net is mainly used, and a forklift mainly uses a pallet.

Examples of the case of using a crane are loading a cargo in a ship or loading a cargo in a ship, etc. The net used at this time is mainly attached to a big crane. Therefore, the net should have rigidity that can overcome the large load, and have the structure to reduce the weight or to send other foreign matter or rainwater, and to have the structure to prevent the grid space from being expanded rapidly.

As described above, the net for conveying cargo has a structure in which a band having a predetermined width is arranged at regular intervals in the shape of a checkerboard, and is sewn and fixed at an intersection.

And four vertices of the net are formed with a hook that can be hooked. In addition, when using only the above-mentioned loops, a large amount cannot be loaded and moved on the net. Therefore, by fastening both ends of the sling to each other by the two loops, the sling may be hooked to the crane even when the large amount of cargo is loaded into the net by the sling. It becomes usable on foot.

Such slings are made of a strong material that can withstand large loads, and in particular, have a high tensile strength. However, when being subjected to a strong tensile force by a large load there is a problem in that it is in a tension state when it is in contact immediately with a sharp break. In the conventional case, all parts of the sling are tensioned, which causes the above problem.

The reason why all parts are subjected to strong tension is the structure of the sling. That is, the sling has a two-ply structure formed by superimposing the upper fabric and the lower fabric so as to have a high strength. And it is formed by stitching and stitching with a binding yarn to tightly fix the upper fabric and the lower fabric integrally. At this time, the binding yarn is sewn on all parts from the end edge of the sling to the center, and when the sling is subjected to the load, the edge of the sling is also tensioned by the binding yarn.

Therefore, when moving the cargo, all parts of the sling are in a tensioned state due to the load, and there is a problem of breaking soon after contact with the sharp part of the edge of the sling.

The present invention has an object to prevent a safety accident that may occur during the movement of the cargo by providing a structure that does not receive a tension force on the edge portion of the sling as described above.

In order to achieve the above object, the present invention provides a structure that is not sewn in the edge portion of the sling to combine the upper fabric and the lower fabric of the sling, the load of the cargo is coupled when the sling is used in the net for the movement of the cargo Even when tensioning the yarns to create tension throughout the sling, the edges of the slings without binding yarns provide an unstrained sling.

When the upper fabric and the lower fabric constituting the sling as described above is sewn together to sew the binding yarn to combine into one, the edge portion is not sewn into the binding yarn, so that even if the load acts on the sling, even if most of the sling is subjected to tension, The edge part is not tensioned and does not break easily even if it touches a sharp part.

Cargo moving net 50 is formed by a plurality of bands 60 arranged horizontally at regular intervals, and a plurality of bands 60 arranged vertically at regular intervals cross each other vertically, the ring 70 at the vertex portion Formed structure. And there is a sling 100 is used to connect the ring 70 and the ring 70.

The present invention is characterized in the structure of the sling (100). The general sling 100 is a two-ply structure formed by superimposing the upper fabric 1 and the lower fabric 2, and the coupling yarn (3) to tightly fix the upper fabric 1 and the lower fabric (2) integrally Is sewn and incorporated. In particular, the conventional binding yarn 3 is sewn to the edge portion 4, which is both ends along the longitudinal direction of the sling 100, so that the upper fabric 1, the lower fabric 2 and the binding yarn 3 are integrated. Structure.

However, the present invention is characterized in that the binding yarn 3 is not sewn on the edge portion 4 of the sling 100, as shown in FIG. That is, the combined yarn 3 sewn in order to integrally combine the upper fabric 1 and the lower fabric 2 is sewn only in the center portion of the sling 100, so that the upper fabric 1 and the lower fabric 2 The edge portion 4 is a structure placed in a free state.

In general, each of the upper fabric 1 and the lower fabric 2 constituting the sling 100 is woven with a warp 5 and a weft 6 as shown in FIG. The upper fabric 1 and the lower fabric 2 are stacked to increase rigidity. At this time, the upper fabric 1 and the lower fabric 2 are attached to each other so as to be bonded to each other. Therefore, the upper fabric (1) and the lower fabric (2) is sewn by the coupling yarn (3) is combined.

However, in the case of the present invention, as shown in FIG. 3, the edges 4 of the upper cloth 1 and the lower cloth 2 are not sewn together with the binding yarn 3.

Due to the structure as described above, the sling 100 of the present invention does not have a feature that does not break even when contacted with a sharp object. That is, when loading the cargo in the net 50, as shown in Figure 1, the sling 100 is fastened to the ring 70 by lifting the crane, etc., the sling 100 is subjected to the tension by the weight of the cargo. The tension force of the sling 100 is pulled by the load of a cargo, and is tensioned. Therefore, in a tense state, the sharp part touches only a little and a small wound (notch) is formed, but is broken by a large tensile force.

However, in the present invention, even when a large load acts on the sling 100 to generate a tension force, the tension force is not generated at both edge portions 4 in the longitudinal direction of the sling 100. This is because, as mentioned above, the binder yarn 3 is not sewn onto the edge 4.

Therefore, even if the sharp portion of the work in contact with the sling 100, there is no problem that the sling 100 is broken, it is possible to prevent safety accidents.
