Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention relates to wiring cables (
This invention relates to a cable insertion tool for inserting cables (cords, electric wires, cables, etc.) into a tubular cable cover.

0002

2. Description of the Related Art Conventional wiring cables are covered with a tubular cable cover having cuts in the length direction, since they may be worn out or damaged if exposed. During construction, the cable cover was attached after the cables were routed, so the cable cover had to be opened by hand and the cables inserted into the cable cover.

0003

[Problems to be Solved by the Invention] In the above-mentioned conventional technology,
Pushing the cable cover apart along the cut not only requires a considerable amount of force, but if the cable cover is very hard (for example, when the temperature is low, such as in the winter), it can easily injure your hands, making it difficult to work. In addition, when the cables have a large diameter or when several cables are housed together in one cable cover, the difficulty of the work increases.

0004

[Means for Solving the Problems] However, in this invention, a cable cover edge guide strip is provided protruding from the outside of two plates arranged in a V-shape, and a cable guide wheel is constructed inside the plates. Therefore, the above problem was solved.

That is, the present invention arranges two plates in a V-shape, movably connects the abutting edges of each plate to form a closed part, and defines the open edges as an open part. A guide strip for the edge of the cable cover is provided protrudingly on the outer lower part of the plate body, a cable guide wheel is installed inside the open part of the plate body, and a traction member of the plate body is attached to the closed part side. This cable insertion tool is characterized by:

[0006] Furthermore, the two plates are a cable insertion tool in which resilient means are interposed on the sides that are separated from each other. Moreover, it is a cable insertion tool in which a smoothing layer is provided on the side of the plate body on which the cable cover edge slides. Furthermore, the cable insertion tool has a plurality of support holes for the shafts of the cable guide wheels drilled on the open side of the two plates so that a plurality of cable guide wheels having different diameters can be selectively installed.

[0007] In the above, the smoothing layer can be formed by applying a tape having abrasion resistance and high sliding properties, or by coating the surface with a paint having abrasion resistance and high sliding properties. It is conceivable to form guide strips from a resin material having wear resistance and high sliding properties (or a material obtained by subjecting the surface of a metal plate to the same treatment) and to protrude from the plate.

[0008]

[Operation] According to the present invention, the plate can be inserted into the cut in the cable cover from the closed part, the edge of the cut in the cable cover is hooked to the guide strip, and there is no fear that the cable cover will come off from the cable insertion tool. Further, the cables are guided inside the cable cover by a cable guide car.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings.

[0010] The two plates 1 and 2 are arranged in a V-shape by elastically bending the plate, and one end edge side where the plates 1 and 2 are connected is a closed part 3, and the other is open. The end edges are respectively open parts 4 and 5. The open parts 3 and 4 of the plates 1 and 2 are bent so as to be parallel to each other. Next, protrusions 6 and 7 are protruded approximately parallel to each other at a predetermined interval from the center of the end of the closed part 3 to the lower part of the end of the open part 4 on the outer lower part of the plate 1. An ultra-high molecular weight polyethylene tape (for example, "Taftalex" manufactured by Nippon Petrochemical Co., Ltd.) is stretched on the side wall of the plate body 1 between 6 and 7 and on the protrusions 6 and 7 to form a guide strip 8. In the above, the ultra-high molecular weight polyethylene tape has abrasion resistance and high sliding properties. Similarly, protrusions 9 and 10 are provided on the outer lower part of the plate body 2, extending from the center of the end of the closed part 3 to the lower part of the end of the open part 5, projecting approximately parallel to each other at a predetermined interval. A guide strip 11 is formed by stretching an ultra-high molecular weight polyethylene tape on the side wall of the plate body 2 between the protrusions 9 and 10 and on the protrusions 9 and 10. In the above, the edges of the cut 23 of the cable cover 22 abut and engage the guide strips 8 and 11, respectively.

Next, a support hole 12 is formed in the open portion 4 of the plate 1.
, 13 are bored vertically at a predetermined interval. Said plate 1
A long hole 14 is bored from the upper edge 1a to connect the edges of the support holes 12 and 13 on the closed portion 3 side. Similarly, support holes 15 and 16 are formed vertically at a predetermined interval in the open portion 5 of the plate body 2. A long hole 17 is bored from the upper edge 2a of the plate body 2 to connect the edges of the support holes 15 and 16 on the closed portion 3 side. The support hole 1
5, 16, and the elongated hole 17 are provided at positions that are linearly symmetrical to the support holes 12, 13, and the elongated hole 14, respectively.

Nuts 25 are attached to both ends of the shaft (threaded at both ends or over the entire length) on which the desired cable guide wheel 18 (FIG. 2(b)), for example for medium diameter, is mounted.
, 25 are screwed together, and the shaft 19 is hooked into the support holes 12 and 15. Further, an annular pulling member 20 is attached to the upper part of the closing portion 5 of the plates 1 and 2 to form a cable insertion tool 21 (FIGS. 1(a) to 1(d)).

In the above, the opening angle of the plates 1 and 2 and the distance between the openings 4 and 5 are determined depending on the diameter of the cable cover to be used. In addition, support holes 12 and 13 (1
The location of holes 5 and 16) is determined by the diameter of the cables to be inserted.

In the above, an example was explained in which the cable guide wheel 18 is used when the cable 24 has a medium diameter (about 40 mm to 60 mm in diameter), but when the cable has a relatively small diameter (about 25 mm in diameter), In this case, Fig. 2(a
), the cable guide wheel 27 is fitted onto the shaft 19, and the shaft 19 is hooked into the support holes 13 and 16. Furthermore, the cable has a large diameter (about 90mm in diameter)
In this case, as shown in Fig. 2(c), the cable guide car 1
An auxiliary car 28 is interposed between the eight guide car pieces 18a and 18b (consisting of guide car pieces 18a and 18b) to constitute a cable guide car 29, and the cable guide car 29 is fitted onto the shaft 19. Then, the shaft 19 is hooked into the support holes 12 and 15. Above 3
By using different types of cable guide wheels 18, 27, and 29, the cable insertion tool 21 can be used for cable covers with a diameter of about 25 mm to 100 mm. In addition, plate bodies 1 and 2
It goes without saying that the cable insertion tool 21 can also be used for a cable cover with a larger diameter if it is formed into a larger size.

Next, the use of the present invention based on the above embodiment will be explained.

A tubular cable cover 22 having a cut 23 in the length direction is prepared in a predetermined length to match the length of the cable 24, and is placed along the cable 24. Insert the cable insertion tool 21 (the cable guide wheel 18 is removed at this time) into the cut 23 at one end of the cable cover 22 from the closed part 3 side, pull the traction member 20, and insert the support holes 12, 13, The cable insertion tool 21 is temporarily stopped with the cables 15 and 16 located near the ends of the cable cover 22. In this state, the plates 1 and 2 are pushed by the cable cover 22 and are closer to each other than originally. Furthermore, the edge of the cut 23 of the cable cover 22 is hooked to the guide strips 8 and 11 of the cable insertion tool 21.

Next, open parts 4 and 5 of cable insertion tool 21
The cable 24 is placed from the bottom to the upper part of the closure part 3 (FIG. 3). Further, nuts 25 are screwed onto both ends of the shaft 19 on which the small-diameter cable guide wheel 27 is fitted. The shaft 19 is inserted through the long holes 14 and 17 so that the nuts 25 and 25 are located on the outside of the plates 1 and 2, and the shaft 19 is inserted into the support hole 1.

Alternatively, one end of two other plates may be connected by a butterfly plate with a spring and arranged in a V-shape.

Further, in the above embodiment, the guide strip 8 was formed by stretching ultra-high molecular weight polyethylene tape on the side wall of the plate 1 between the protrusions 6 and 7 and on the protrusions 6 and 7. A tape based on Teflon (such as "Teflon") may also be used. Alternatively, the portion may be painted with a paint having abrasion resistance and high sliding properties. Furthermore, the side wall of the plate body 1 between the protrusions 6 and 7 and the protrusions 6, whose surfaces are made of a resin material having wear resistance and high sliding properties (or a material obtained by applying the same treatment to the surface of the metal plate);
It is also possible to form a member with a groove-shaped cross section including 7 and attach it to the side wall of the plate body 1 (not shown). Alternatively, similar smoothing treatment can be performed using other materials than those mentioned above. The point is that the edges of the cut 23 of the cable cover 22 can be smoothly abutted, and the friction between the edge of the cut 23 and the cable insertion tool 21 should be as small as possible. Said guideline 1
1 is also the same as the guide strip 8.

Furthermore, in the embodiment described above, the protrusions 6, 7 extend from the central part of the closed part 3 to the lower part of the open part 4 (that is, with a downward slope from the closed part 3 side to the open part 4 side).
Since the guide strip 8 is formed by protruding, the cable cover 2
Although the cable insertion tool 21 can be easily inserted into the cable cover 2 and the cable 24 can also be easily inserted into the cable cover 24, the protrusions 6 and 7 can also be provided to protrude almost horizontally from the outside of the plate body 1. (not shown). This also applies to the guide strip 11.

Further, in the above embodiment, the guide strip 8 was formed by protruding the protrusions 6 and 7 on the outside of the plate 1.
It is also possible to form guide strips by forming grooves at the positions of the protrusions 6 and 7 (not shown). This is guide article 1
