Description

Description: TECHNICAL FIELD The present invention relates to a grip of a linear body, and an electric wire when a lightweight structure that is easy to mount and remove is desired.
The present invention relates to a winding grip for tensioning or holding an intermediate position or an end of a wire or the like.

(Prior art and problems) Conventionally, when suspending the extension work of a transmission line on the way, in order to prevent the electric wire from falling into the span between both sides due to wind, etc. It was intended to be connected and fixed to. As a means for this, as shown in FIG. 6, a wedge type gripping tool called a cam along 5 is used for fixing. This method has a risk of damaging the surface of the electric wire with wedges, and is not only difficult to handle due to its weight, but also if it slips by hand, it may cause damage to ground workers.
Moreover, if the electric wire moves during the work of attaching the cam alloy to both sides of the gold wheel, the cam alloy may collide with the gold wheel and be damaged.

(Means for Solving the Problems) Therefore, in the present invention, a gripping tool called a winding grip, not a wedge-type gripping tool, is formed of a soft fiber belt for gripping an electric wire, and the belt has a double structure, and a predetermined structure is provided. The overlapping part and the separating part are provided at intervals, and when winding around the electric wire etc., the other belt is inserted and crossed to the separating part so that the electric wire etc. can be gripped tightly, and the stronger the tensile load, the tighter the gripping force. Get stronger, slackening effect,
It aims to solve the problem by reducing weight, maintaining strength, and improving operability. By using a flexible structure,
It is widely applicable to various electric wires with different diameters.

(Example) As an example of the present invention, a multi-layer belt having a two-layer structure is constructed by using synthetic fibers such as nylon, polyester, and aramid. The superposed portions 2 each having one sheet and the separation portions 3 each having two sheets are alternately arranged at a predetermined interval of the multiple belt, and a plurality of superposed portions 2 are provided on both sides with an arbitrary superposed portion 2 as a center. Then, the belt arms 4 having the same length or different lengths having the separation portion 3 are arranged. In use, for example, the intermediate polymerized portion 2 described above on a predetermined intermediate position of an electric wire or the like.
Are arranged, and they are pulled into the separated portions 3 of both belt arm portions 4 from the tips thereof and knitted as shown in FIG. The tips of both belt arm portions 4 which have become extra length are fixed to the electric wire by a grip member such as tape. The intermediate overlapping portion forms a ring-shaped hanging portion by being pulled, and the stronger the force applied to the hanging portion, the greater the force pressing the superposed belts at the separated portions from each other, resulting in a larger wire gripping force. It is what is done.

In the present embodiment, the synthetic fiber belt is provided with the overlapping portion and the separating portion at predetermined intervals at the weaving stage, but as another embodiment, two synthetic fiber belts are sewn at predetermined intervals to overlap the overlapping portion. The same effect can be obtained by providing a separating part.

Further, as another embodiment, one of the belts to be polymerized is configured to have a weaker belt strength, and even if one portion of the polymerized portion is cut when a tensile force of a predetermined value or more is applied, the use is stopped at that point, which is important. The fuse is designed to prevent it from overlapping, or the overlapping belts can be colored differently, and a certain pattern can be configured when inserting and crossing through the separation part to knit, and the insertion sequence and winding side can be confirmed, or If the distance between the overlapping portion and the separating portion is close to the tip of the belt arm and becomes coarser toward the suspending portion or vice versa, more reliable gripping can be achieved.

Further, as shown in FIG. 3, the belt arm portion is made long and short, the separation portion is arranged on the short side, and the long side is made into a normal belt shape, which facilitates the braiding.

(Effect of the Invention) As described above, by using the belt winding grip of the present invention, compared to the conventionally used wedge-type gripping tool,
It is possible to obtain a linear body gripping tool that is lightweight, has good operability, and does not damage the target linear body such as an electric wire, and can perform work in high places safely and efficiently.

Claims (3)

[Claims] 1. A narrow-weave belt 1 is formed by using a single or composite product of synthetic fibers such as nylon, polyester, and aramid. The belt 1 is multi-layered in the thickness direction or width direction, and the multi-belt is polymerized. A part 2 and a separation part 3 are provided, a predetermined part is folded back to form a pair of belt arm parts 4, and one of the belt arm parts 4 is separated from the other so that the predetermined overlapping part 2 becomes a loop-shaped suspension part. A belt winding grip characterized in that the belt arm portions 4 are wound around the tension target object such that the two belt arm portions 4 cross each other along the tension target object such as an electric wire. 2. The belt winding grip according to claim 1, wherein the pair of belt arm portions 4 are configured such that the overlapping portions 2 and the separating portions 3 are alternately arranged at predetermined intervals on both sides. 3. The pair of belt arm portions 4 are characterized in that one of them is alternately formed with a superposed portion 2 and a separated portion 3 at predetermined intervals, and the other is formed with only a superposed portion 2. The belt winding grip according to Item 1.
