Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wire passing device for inserting wired materials such as electric wires and cables into a tubular body.

[Conventional technology and its problems]

Conventionally, as this type of wiring device, there was a
No. 15207 is known, in which the tip of the support rod to which the winding drum is attached is inclined slightly upward, but because of its smooth outer circumferential shape, the tip can be brought into contact with a distribution board or cubicle to prevent it from being covered. When trying to resist the reaction force of the pulling force on the wiring material, it becomes slippery and sufficient reaction force cannot be obtained. Therefore, it was necessary to secure the base end of the support rod with a rope or the like. As described above, the conventional wiring device takes time and effort to set up (fix), and it is also quite difficult to perform the work safely, reliably, and quickly.

[Means for solving problems]

The present invention involves inserting a filament into a tubular body, connecting its tip to a wired material, and pulling the wired material into the tubular body while winding the other end of the filament to wire the wire. In the apparatus, a locking notch recess for locking to other members such as a distribution board or cubicle is provided at the tip of a support rod equipped with a winding drum for winding the wire. There is.

[Effect]

The locking notch recess is connected to the protruding lower wall of a distribution board, the threshold of a cubicle, or a protrusion of a building, and the tip of the support rod is rested against the base of the support rod. A stable posture can be maintained simply by the worker holding it down. This allows safe and reliable wiring work.

〔Example〕

The illustrated embodiment will be explained in detail below.

In the schematic diagram shown in FIG. 5, 1 is a filamentous body such as a wire or a call line, and the wire passing device W of the present invention is equipped with a winding drum 4 for winding the filament body 1. The filamentous body 1 is fed out from the tube and inserted into the tubular body 2 such as the piping of a building.
Insert it in the direction of arrow A, pass it from one end 5 to the other end 6 of the tubular body 2, and then insert it into the tip 7 of the filamentous body 1.
The wired materials 3 such as electric wires and cables are connected, and then,
By winding the other end of the filament body 1 with the winding drum 4, the wiring material 3 is pulled into the tubular body 2 and wired as shown by arrow B in the figure.

As shown in FIGS. 1 to 5, this wiring device W has a support rod 8 that is approximately T-shaped in plan view.
The winding drum 4 for winding up the filament 1 is attached to the center of the support rod 8 or slightly closer to the base end 9. The base end 9 of the support rod 8 serves as a handle portion 10, which is useful when carrying and setting up the device.

The winding drum 4 is driven by an electric motor 11, and the motor 11 is connected to the winding drum 4 via a speed reduction mechanism.
In the figure, an operation panel 12 is provided in the vicinity.

Also, in Figures 3 and 4, 13 is the clutch;
14 exemplifies an electrical cord.

The support rod 8 includes a main body 8a made of a square pipe, channel material, or the like, and a pair of left and right parallel roller holding pieces 15 fixed to the tips of the main body 8a.

More specifically, this roller holding piece 15 includes a mounting neck piece 16 that is fixed to the main body 8a,
It has a substantially rectangular piece 17 connected to its tip, and a support shaft 18,
Two rollers 20 and 21 are rotatably connected via a roller 19.
are pivotally attached to each other, and locking notch recesses 22 are formed by cutting out the corners of the lower side and the tip side of the substantially rectangular piece 17 in a stepped manner.

After all, the tip of the support rod 8 is connected to other members such as the lower wall edge of the distribution board 23 as shown in FIG. A locking notch recess 22 that locks and receives a reaction force...
... are provided one or more. In this way, during wire threading work, the distal end of the support rod 8 of the wire threading device W is reliably supported without slipping due to the engagement between the other member G and the notch recess 22, but the proximal end The handle portion 10 is held by an operator by pressing it against a floor surface or the like with a foot or hand. In other words, it is not necessary to secure the handle portion 10 with a rope or the like as in the conventional case.
When the electric motor 11 is used as shown in the figure, the force for winding the wire body 1 is strong and the wire threading work can be carried out quickly, but on the other hand, a large reaction force acts on the support rod 8. I will do it. However, in the present invention, the locking notch recess 22 at the tip of the support rod 8 can sufficiently withstand this large reaction force, allowing smooth, reliable, and safe work.

In the illustrated embodiment, two rollers 19,
20, a pair of parallel roller holding pieces 15, 15
It has the advantages of a simple structure and high rigidity.

It should be noted that the present invention is not limited to the illustrated embodiment and is open to various design changes, and it is also preferable to install a manual handle in place of the motor 11. In addition, as shown by imaginary lines in FIG.
It is also possible to form a cutout recess 22 at the tip side of the housing, or to lock it to a part of a bar (steel frame part) of a building.

[Effect of idea]

The present invention has the following significant effects due to the above-described configuration.

The locking notch recess 22 securely fixes the position of the tip of the support rod 8 without slipping. Therefore, it can withstand a large reaction force and strongly move the filament body 1 to the winding drum 4.
By winding it up, wire wiring work can be carried out quickly and safely and reliably.

The operator only needs to lightly hold the base end of the support rod 8 with his or her hands or feet, reducing fatigue. In particular, since it is no longer necessary to tie the support rod 8 to other members with a rope or the like in the past, work efficiency is significantly improved when moving from one site to another while passing wires through a large number of tubular bodies 2 one after another. can be improved.
