Description

  The present invention relates to an electric wire work auxiliary tool that is used when a rising operation is performed on an electric wire during work on the electric wire. Specifically, it is easy to get up on the electric wire by standing up on the scaffolding part by providing a detachable attachment means to the electric wire, a scaffolding part, and a foldable connecting part for connecting the attachment means and the scaffolding part. It is possible to perform the operation.

  When performing various types of work using electric wires installed in high places such as utility poles and steel towers, an operator needs to perform work and move the work place while riding on the electric wires. FIG. 9 is an explanatory diagram showing the basic posture of the worker 11 when working on the electric wire 2. Normally, the operator 11 takes a basic posture as shown in FIG.

  FIG. 10 is an explanatory diagram showing a rising operation on the electric wire 2 of the worker 11. When the operator 11 falls from the electric wire 2 due to falling on the electric wire 2, as shown in FIG. 10, either one leg is put on the electric wire, and the electric wire 2 rises on the electric wire 2 by a kick-up method. I need to go back up.

  Further, as a tool for assisting work on the electric wire, an electric wire aiding tool for assisting work on the inclined electric wire has been proposed (for example, Patent Document 1).

  The electric hoisting auxiliary tool disclosed in Patent Document 1 includes a base body on which work shoes are placed, a fastener for fixing the work shoes to the base body, and a rod body projecting outward from the central portion of the base body. Further, the electric wire hoisting auxiliary tool disclosed in Patent Document 1 includes a horizontal straight rod extending backward and a curved rod projecting upward at the tip of the rod body, and an electric wire at the rear end of the straight rod and curved rod. Has an opening into which.

  With such a configuration, the wire in the inclined state can be easily moved up and down and stopped at a desired position.

Mounting means to be attached to the body, a scaffold part on which the operator places his / her foot, and a foldable connecting part having a length corresponding to the size of the worker's body and connecting the attachment part and the scaffold part. It is a feature.

  In the electric wire work auxiliary tool according to the present invention, the worker gets up on the electric wire by the following method. The operator takes out the electric wire work auxiliary tool that is folded and stored, and attaches it to the electric wire by the attaching means.

  Thereafter, the worker puts one of the feet on the scaffold, and stands on the scaffold by standing on the foot placed on the scaffold.

  The worker then lifts the other leg over the wire, hangs on the wire, and rides on the wire while rotating his body. After getting up on the electric wire, the operator removes the electric wire work auxiliary tool from the electric wire, folds it, and stores it.

  According to the electric wire work auxiliary tool of the present invention, the worker can stand on the scaffold portion with either one of the legs during the rising operation on the electric wire. After standing on the scaffold, the worker gets on the electric wire while putting his other leg on the electric wire and rotating his body.

  As a result, the rising operation on the electric wire can be easily performed, and even an inexperienced worker with little experience can easily perform the rising operation on the electric wire.

  Moreover, since the electric wire work auxiliary tool of this invention is a simple structure provided with the attachment means, the scaffold part, and the connection part, it can be produced easily and at low cost.
