Description

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

[Conventional technology and its problems]

Conventionally, in order to insert a wired material such as a cable into a tubular body, it was done by inserting a call wire into the tubular body, connecting the wired material to one end of the call wire, and pulling the other end of the call wire. I was walking along. Further, if the tubular body has many bends or has a long distance, the resistance force for pulling the wired material becomes large. In this case, a wire threading device equipped with a winding means for winding a wire such as a steel cable was used. When using this wiring device, a part of the body was brought into contact with the vicinity of the tubular body to resist being drawn in by the reaction force. Generally, since the body of the wiring device is applied to the wall near the outlet of the tubular body, it is possible to pull the wired material to the outlet of the tubular body, but it is possible to pull the material to be wired up to the outlet of the tubular body. It was difficult to pull it out. In other words, there are many work sites where it is difficult to fix the wiring device at a distance of, for example, 1 to 2 meters from the outlet.

The object of the present invention is to provide a wiring device that solves the above problems.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention includes a winding drum for winding up a filament body to which a wired material is connected to one end, a support rod to which the winding drum is attached to the proximal end side, and a support rod for winding the wire body to which the wired material is connected at one end. and a support arm pivotally attached to the support rod, and a pair of rollers attached to the tip of the support rod for guiding the wire body to the winding drum. one end of the support arm is swingably pivoted to the tip of the support rod, and a base end of the support rod,
A mounting portion that is substantially orthogonal to a plane including the support rod and the support arm is provided in series, and a contact piece portion that is substantially orthogonal to the plane is provided in series to the other end of the support arm.

[Effect]

The support arm has legs spread apart from the support rod, and the contact piece of the support arm is attached to a step near the outlet of the tubular body (through which wired materials such as electric wires and cables are inserted), a ceiling, etc. When the filament is wound up by rotating the winding drum while in contact with the contact surface, the wired material is inserted into the tubular body while receiving the reaction force acting on the winding drum with the support arm.

That is, the end of the wired material can be pulled out to the vicinity of the tip of the support rod, and in this case, since the support arm has a leg-like shape with respect to the support rod, the tip of the support rod can be pulled out near the tip of the tubular body. It is arranged at a position spaced apart from the outlet, and the end of the wired material can be pulled out to a position spaced apart from the outlet of the tubular body.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a filamentous body such as a steel cable, which is used to insert a wired material 2 such as a cable or electric wire into a tubular body 3 such as a pipe or tube. 4 is a wiring device according to the present invention, as shown in FIG. This device pulls the wired material 2 into the tubular body 3 and inserts the wired material 2 into the tubular body 3. Reference numeral 8 denotes a connecting portion between the wired member 2 and the wire member 1, and the wire member 1 is inserted into the tubular body 3 in order to connect one end 5 of the wire member 1 and the wire member 2. In addition,
Although not shown in the drawings, the filament 1 is inserted into the tubular body 3 by inserting a nominal wire such as a piano wire into the tubular body 3 from the lead-in port 7 side, and connecting one end 5 of the filament 1 with the wire from the lead-in port 9 side. This is done by connecting them, and then pulling out the one end 5 of the filament 1 to the inlet 7 by pulling the reference line.

Thus, the wire passing device 4 according to the present invention includes a winding drum 10 for winding up the filament 1, a support rod 12 to which the winding drum 10 is attached to the base end 11 side, and a support rod 1.
The support arm 15 has one end 14 swingably supported at the tip 13 of the second arm. The winding drum 10 is driven by a motor 16 with a reduction gear.
The operation panel 17 of No. 6 and the motor 16 are both connected to the support rod 12.
It is attached to the proximal end 11 side of the. Support rod 12
is made of a square pipe or the like, and the base end 11 thereof is connected with a mounting part 28 made of pipe material, and the distal end 1
3 is connected with a roller holding member 19. Further, the roller holding member 19 has a U-shaped cross section and a substantially U-shaped side view, and its base end is fitted onto the tip 13 of the support rod 12 .

Thus, the support arm 15 is composed of a main body part 15a made of a square pipe or the like, and a pivot part 15b connected to the main body part 15a.
b consists of a pair of side walls 30, 30 and a bottom wall 31 having a notch 23 (see FIG. 2).

That is, the proximal end portion of the roller holding member 19 is held between the tips of the side walls 30, 30 of the pivot portion 15b, and in this state, the support arm 15 is pivotally attached to the support rod 12 via the pivot pin 22.

Therefore, the support arm 15 swings about the pivot pin 22 as shown by arrow A with respect to the support rod 12.

During this swinging, the support arm 15 has the notch 23 as shown in FIG. 2, so it can swing without being restricted in any way.

Furthermore, a contact piece 21 made of a pipe material or the like is connected to the other end 32 of the support arm 15 .

In this case, the contact piece portion 21 and the mounting portion 28 are substantially perpendicular to a plane including the support rod 12 and the support arm 15.

At the tip 13 of the support rod 12, a striated body 1 is attached.
A pair of rollers 24, 25 for guiding the material to the winding drum
is attached. That is, the rollers 24 and 25 are
It is attached to the roller holding member 19.

Next, in order to insert the wired material 2 into the tubular body 3 using the wire passing device 4, as shown in FIG. 5 is connected to the wired member 2, and the contact piece 21 of the arm 15, that is, the other end, is brought into contact with the vicinity of the outlet 9 or other locations. This contact surface 26 is
Since the filament 1 receives the reaction force when it is wound around the winding drum 10, when the filament 1 is pulled in the horizontal direction as shown in the figure, the step part of the concrete floor G is suitable. be. By starting the motor 16 using the operation panel 17 and rotating the winding drum 10 while the contact piece portion 21 is in contact with the contact surface 26, the filament 1 is sequentially moved around the winding drum 10. wrapped around.
As shown by the imaginary line, the wired material 2 can be pulled out to the vicinity of the tip 13 of the support rod 12. Therefore, the distance from the outlet 9 to the end P of the wired material 2, that is,
The length L of the wired material 2 drawn out is at least about the length of the support arm 15. Note that the operator needs to hold the support rod 12 so that the arm 15 does not stand during this time, and the illustrated example shows a case in which the support rod 12 is spread downward relative to the arm 15.

FIG. 5 shows the case where the wired material 2 is pulled out downward from the outlet 9 of the tubular body 3, and the abutting surface 26 is a ceiling wall, an upper wall surface of a distribution board, or the like.

Unlike the case of the above-mentioned embodiment, it is preferable that the support arm 15 is pivotally attached to the middle part of the support rod 12.

In the above embodiment, a case is shown in which a call wire is used to insert the filament 1 into the inlet 7 where the wired material 2 is placed, but unlike this, the filament 1 can be inserted independently. It is also preferable to feed it into the tubular body 3 and insert it into the tubular body 3. In this case, the filament 1 is made of piano wire, spring wire, or the like.

It is also preferable to use a structure in which a manual handle is rotated instead of the motor 16 to wind the winding drum 10 via a speed reduction mechanism. It is also preferable that the pivot pin 22 be freely inserted and removed so that the arm 15 can be removed.

[Effect of idea]

Since the present invention is constructed as described above, it produces the following effects.

The end P of the wired material 2 is connected to the tip 13 of the support rod 12.
It can be pulled out to the vicinity, and at this time, the support arm 15 becomes open-legged with respect to the support rod 12, so
The tip 13 of the support rod 12 is arranged at a position spaced apart from the outlet 9 of the tubular body 3, and the end P of the wired material 2 is arranged at a position spaced apart from the outlet 9 of the tubular body 3 (for example,
It can be pulled out to a position approximately 1 to 2 meters away from the drawer opening 9.

Therefore, if this wiring device is used, the wired material 2 can be pulled out with sufficient margin on the drawer side, and the wired material 2 can be pulled out artificially to ensure the margin on the drawer side. There is no need to draw it out, and the wired material 2 can be easily and quickly inserted into the tubular body 3.

A mounting part 28 is connected to the base end 11 of the support rod 12, and a contact piece part 21 is connected to the base end 32 of the support arm 15.
Since these are connected in series, the wire passing device can be held in a stable state, and a stable wire passing device can be performed.

Since the support arm 15 is swingable with respect to the support rod 12, the support arm 15 can be moved depending on the mounting location.
The position and posture of can be changed freely.
