[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulation arm for penetrating a distribution line to save labor in power distribution work.

[0002]

2. Description of the Related Art A commonly used arm for a distribution line to be attached to a utility pole is, for example, an arm with a rectangular pipe of a predetermined length formed of rolled steel or the like and galvanized, and When mounting on a utility pole, the metal fittings for attaching the utility pole and the wire stoppers such as pin insulators must be fixed in place to the main body of the utility pole by bolts, etc., in an appropriate number beforehand. Is required. Of course, this type of conventional arm bracket requires a large number of equipment (insulators and hardware), and this requires a great deal of work.

[0003]

In recent years, however, a mobilization method has become indispensable so that labor can be saved even in a power distribution operation. In other words, the power distribution work using the robot-mounted vehicle has also adopted the robot construction method, and improvement of hardware such as armatures for distribution lines has been required to be suitable for the robot construction method. For example, we have waited for the provision of products that are lighter in weight using an insulative synthetic resin material for the arm body, labor saving in the work of attaching wire locking members such as pin insulators to be attached to the arm, and simplification of handling. Have been.

[0004] In view of the above circumstances, the present invention solves the above-mentioned problem by distributing the arm member main body to FRP, which can reduce the weight, and integrating the electric wire locking portion (clamp portion) with the arm member main body. The purpose of the present invention is to provide an insulation arm for a lead wire.

[0005]

SUMMARY OF THE INVENTION The present invention provides a hollow prismatic arm body made of an insulating member such as FRP having a predetermined length and horizontally mounted on a utility pole, and has both ends of the arm body and On a top surface of a plurality of places such as an intermediate portion, a clamp body pedestal portion of an insulative member such as the FRP provided with an electric wire receiving groove orthogonal to the longitudinal direction of the arm body is formed integrally, and faces the electric wire receiving groove. An insulative material in which an electric wire holding member of an insulating member such as the FRP provided with an electric wire holding groove is pivotally connected at one end to the clamp body pedestal side and tightened with a tightening means of a tightening bolt or a compression coil spring. Configure the clamp body,
A wire which is formed by winding a normal-temperature-fused spiral tape for a predetermined length to an appropriate thickness according to the wire diameter in a fixed holding gap arranged between the wire receiving groove of the insulating clamp body and the wire holding member. It is.

In addition, a prismatic arm body made of an insulating member such as a hollow FRP having a predetermined length and having hooked attachment pieces disposed at upper and lower ends vertically mounted on a telephone pole is formed. The FRP in which a wire receiving groove orthogonal to the longitudinal direction of the arm body is provided on a plurality of side surfaces such as upper and lower portions and an intermediate portion.
The pedestal part for the clamp body of the insulating member such as
The FRP having an electric wire holding groove facing the electric wire receiving groove.
An insulative clamp body portion integrally formed with one end of the wire holding member of an insulative member, etc., being pivotally connected to the clamp body pedestal portion side by a fastening means such as a fastening bolt or a compression coil spring; and A wire which is wound with a normal temperature fusion spiral tape by an appropriate thickness according to the wire diameter over a predetermined length in a certain holding gap arranged between the wire receiving groove of the insulating clamp body and the wire holding member, and holds the wire. is there.

[0007]

[0008]

[0009]

In this manner, the prism arm body is formed from an insulating member such as FRP, and a locking device for a distribution line (hereinafter simply referred to as an electric wire) is separately formed with a part of the arm body. Since the wire clamps made of insulating material are combined to form an integral clamp body, there is no need to assemble a set of equipment such as a power distribution insulator for the arm body as in the past when mounting on a utility pole. It is sufficient to fix the sex arm at a predetermined position of the utility pole with an appropriate fitting, and clamp the extended electric wire to the clamp body integrated with the arm body.
In this case, if the configuration of the clamp body uses a tightening bolt,
The clamping bolt is removed, the wire holding member is opened, and the electric wire is guided between the opposed wire receiving groove and the wire holding groove. In the case where the clamp body is of a boltless type, the operating bolt for opening is pushed in to open the electric wire holding member against the elasticity of the compression coil spring, and in this state, the electric wire is guided and the spring is merely pulled out to remove the opening bolt. Since it grips with pressure, it is suitable for, for example, a robot construction method that prefers one-touch operation. In addition, since the wire wound with the normal temperature fusion spiral tape is clamped between the wire receiving groove and the wire holding groove of the clamp body, it can be used for various wire sizes by adjusting the number of windings (layers) of this spiral tape. Becomes

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

FIGS. 1 and 2 show an embodiment of an insulated arm of horizontal mounting type in which the locking of the clamp body is a bolt-tightening type. Reference numeral 1 denotes a hollow prismatic arm body having a predetermined length formed of an insulating material 2 made of FRP.
A semicircular arc-shaped wire receiving groove 3 is provided on one side of the upper surface at both ends and an intermediate portion of a, and a clamp body pedestal portion 5 for three wires having a screw hole 4 formed on the other side is integrally formed. And
On the upper part of each pedestal portion 5 for the clamp body, an electric wire presser 6 provided with a semicircular electric wire press groove 3 'corresponding to the electric wire receiving groove 3 on the lower surface formed of the insulating material 2 made of the same FRP is mounted. One end of the wire holding member 6 is pivotally attached to the clamp body pedestal portion 5 side with the connecting pin 7 and the other end of the wire holding member 6 is screwed into a fastening bolt 8 serving as fastening means. The lower end screw portion is screwed into the screw hole 4 on the side of the pedestal portion 5 for the clamp body to form an insulative clamp body portion 9, and these components constitute an insulating arm 10 for penetration.

Next, a description will be given of this operation. First, when the insulating arm 10 is horizontally mounted on the electric pole A, a band-type mounting bracket 11 previously attached to the side surface 1b of the insulating arm 10 is used.
Of the mounting bolts 13 connecting and connecting the one split band portion 11a to both sides between the fixed band portions 11b, the head 13a of at least one of the mounting bolts 13 is turned so that the locking holes 12 are formed.
, The divided band portion 11a is spread (rotated) and wound around the telephone pole A, and then the mounting bolt 13 is connected to the fixed band portion 11b in the opposite direction to the above, so that band fastening is performed. The insulation arm 10 is fixed to the side of the utility pole A.

Here, each of the three insulative clamp bodies 9 protruding from the upper surface of the insulated arm 10 and the electric wire presser 6 covering the upper part thereof are turned by the tightening bolts 8 and the clamp body pedestal part 5 is turned. When the wire holding member 6 is pulled out from the side, the wire holding member 6 is opened with the connecting pin 7 on one side as a fulcrum, and the pedestal portion 5 for this clamp body is opened.
Guides the wire B extended into the wire receiving groove 3 of the above, covers the wire holding tool 6 opened on the upper surface of the wire B, and tightens the bolt 8
Is screwed into the screw hole 4 of the pedestal portion 5 and the wire holding member 6 is pressed, the wire B is held between the opposed wire receiving groove 3 and the wire holding groove 3 ', and is held in a predetermined manner. Hereinafter, similar clamping work is performed for the remaining two wires B.

In this case, since the arm body 1 and the clamp body 9 are formed of the insulating material 2 made of FRP, the electric wire B is connected to the clamp body 9 without using the insulator used in the conventional arm. It is easy to handle by simply holding it directly.

When gripping the electric wire B with respect to the clamp body 9, as shown in FIG. 3, a normal temperature fusion spiral tape 20 is attached to the gripped portion of the electric wire B having an appropriate size (outer diameter). If a predetermined thickness is wrapped over a predetermined length so as to correspond to the fixed holding gap provided by the receiving groove 3 and the wire holding groove 3 ', the opposite wire receiving groove 3 and the wire holding groove 3' ensure the winding. A predetermined set can be made by clamping and clamping. That is, by arranging (winding) the appropriate number of the normal temperature fusion spiral tapes 20 concentrically, the outer diameter of the electric wire can be substantially equalized, and the arm having the clamp body 9 corresponding to various electric wire sizes can be achieved. Even if the gold main body 1 is not aligned and the spiral tape 20 is worn, the coating of the electric wire is prevented from being damaged, and the heat generated by the electric wire coating material at the gripping portion is dissipated.

For example, when the electric wire B is used with a small diameter, a small-diameter cylindrical cold-sealing spiral tape 20a suitable for the electric wire B is inserted from the spiral cut line 21 and set. Similarly, a large-diameter cylindrical normal-winding spiral tape 20b for upper winding is inserted from the score line 21 and set to form a double winding structure (FIG. 4A).
(Refer to FIG. 2), and are clamped so as to correspond to the diameter of a pair of the wire receiving groove 3 and the wire holding groove 3 ′ (clamped in a fixed wire groove). That is, the change in the wire size (diameter) is adjusted by the number of windings of the normal temperature fusion spiral tape 20.

[0040]

As described above, the insulated arm for a lead-through wire of a distribution line according to the present invention has a main body made of an insulating material such as FRP and is provided at a position where the electric wire is locked (fixed). By providing the arm body and the pedestal portion for the clamp body, the wire holding member facing the pedestal portion is also formed of an insulating member such as FRP to integrally form the insulating clamp body portion. It is lighter in weight, and there is no need to attach various wire fixing devices such as pin insulators each time as in a conventional metal arm, so that the number of equipment is reduced and handling becomes easier. That is, since the insulating arm of the present invention has a small number of equipment and is set, it is effective in shortening the construction time, saving labor, and mobilizing. Further, since the wire inserted between the wire receiving groove and the wire holding groove of the insulating clamp body is to be wound with a normal temperature fusion spiral tape, the coating is prevented from being damaged by gripping the clamp, and the normal temperature fusion spiral tape is used. By selecting the number of windings, even those of various electric wire sizes (outer diameters) can be sandwiched and gripped by the clamp body having a predetermined shape (the same outer diameter of the electric wire).
Of course, the number of equipment is small, so the entire mounting column is compact and the landscape is good. In particular, when the wire gripping mechanism of the insulating clamp body is mounted with a compression coil spring that presses the wire holding member against the pedestal portion in addition to the tightening bolt, the opening operation bolt only needs to be operated during the clamping work. It is easy to handle, and has effects such as being suitable for a manipulator construction method using a robot vehicle.
