Abstract

PURPOSE:To enable a roller position on a cable rack to be selected freely and to enable cables ranging from flat to round ones to be laid, by mounting and fixing a position adjusting lever along the upper and lower horizontal arms and by providing a supporting frame, on which a roller is installed that rotates while contacting cables, on the lever in such a way that the frame can be mounted and dismounted easily. CONSTITUTION:A pair of horizontal arms 3 are temporarily mounted on the upper and lower sides of supports 1. A position adjusting lever 5 is mounted along the arms 3 in such a way that its position can be adjusted freely. A supporting frame 6, mounted on the lever 5 in such a way that it can be attached and detached freely, is provided with a roller that rotates while contacting cables. The supporting frame 6 is designed to be fixed by inserting the position adjusting lever 5 into a suitable position. A horizontal roller 7 and vertical roller 8 are mounted on the supporting frame 6 to form a linear extension roller 10. A flat cable Q1 can be supported vertically by installing line linear extension roller 10 in parallel with the vertical roller 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a cable drawing roller suitable for laying a flat cable or a round cable on a cable rack.

[0002]

2. Description of the Related Art Conventionally, this type of cable drawing roller is
It is known that a roller body rotating in contact with a cable and a main body for fixing the roller body to a cable rack are integrated (see Japanese Utility Model Publication No. 3-36175). This cable extension roller fixes the roller on the main body and allows this roller to protrude upward from the bottom of the cable rack.The main body has a structure that is fixed to the main girder from the bottom surface of the cable rack with one touch. Was there. As a result, the cable drawing roller can be easily attached. In addition, the structure of this roller body is such that the inverted L-shaped roller composed of a horizontal portion and a vertical portion is extended from one end of the horizontal roller body to prevent the escape of the cable during wiring. There is.

[0003]

However, according to such a conventional cable drawing roller, since the roller and the main body are integrated, the position of the roller can be changed when the width of the cable rack is wide. There was an inconvenience that it could not be changed easily.

Also, since the structure of the roller body is substantially U-shaped as a whole, it is suitable for wiring a round cable, but it is suitable for wiring a flat cable with its width raised. Was difficult, and there was a problem in dealing with flat cables.

Therefore, the present invention was created to solve the above-mentioned problems. It is easy to put on and take off, and the position of the roller on the cable rack can be freely selected. An object of the present invention is to provide a cable wire drawing roller that can be used.

[0006]

In order to achieve the above-mentioned object, the present invention provides a pair of horizontal arms 3 above and below a column 1 fixed to a main beam P1 of a cable rack P, and the horizontal arm 3 extends in the longitudinal direction. A position adjusting rod 5 whose mounting position is freely mounted is fixed between the upper and lower horizontal arms 3, and a support frame 6 provided with a roller body which rotates in contact with the cable Q is attached to the position adjusting rod 5.
It is provided to be removable.

Further, a horizontal roller body 7 and a vertical roller body 8 are provided on the support frame 6 to form a linear roller 10.
The length of this straight line roller 10 is the flat cable Q1.
Form shorter than width.

Further, the horizontal roller body 7 is provided between the pair of vertical roller bodies 8 arranged side by side on the support frame 6 to form the corner roller 20 as means for solving the problem.

[0009]

In other words, the cable drawing roller of the present invention is mounted by fixing the column 1 to the main beam P1. Then, by changing the mounting position of the position adjusting rod 5 in the horizontal arms 3 provided above and below the column 1, the position of the roller is adjusted in the horizontal direction.

The straight line rollers are arranged at appropriate intervals on the straight line portion of the cable rack P. When the straight line rollers are opposed to each other, they support the flat cable Q1 in a widthwise state. become.

The corner rollers support the cables Q at the portions where the cable rack P is bent horizontally.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 shown in the drawing is a column vertically fixed to the cable rack P (see FIG. 1). This strut 1 is provided on the outer side of the main girder P1 so as to be opposite to each other.
In the illustrated example, a U-shaped bolt bent in a U-shape is used to connect the connecting tool 2
Is used as.

A pair of horizontal arms 3 are horizontally installed above and below the column 1. The horizontal arm 3 is for mounting a position adjusting rod 5 which will be described later so that the position can be adjusted freely.
The horizontal arm 3 shown in the drawing has a plurality of insertion holes 3A penetrating in the vertical direction, and selects the insertion holes 3A to insert a pin-shaped position adjusting rod 5. At this time, the horizontal arm 3
The mounting means of the position adjusting rod 5 and the position adjusting rod 5 is not limited to this example, and any means may be used as long as the position adjusting rod 5 can be mounted on the horizontal arm 3 in a positionally adjustable manner. Further, although the bolt 4 is used to connect the horizontal arm 3 and the column 1, a pin having a retaining mechanism may be used instead of the bolt 4.

The support frame 6 is detachably attached to the position adjusting rod 5. The support frame 6 is provided with a roller body that rotates in contact with the cable Q. At this time, the support frame 6 has a structure in which it is fixed by inserting the position adjusting rod 5 at an appropriate position of the support frame 6. Further, the horizontal roller body 7 and the vertical roller body 8 are provided on the support frame 6 to form the linear roller 10.
Then, the cable racks P are arranged at appropriate intervals (for example, when supporting the flat cable Q1 at a pitch of 3 m). In addition, this straight line roller 10
By arranging the vertical roller bodies 8 side by side,
A flat cable Q1 having its width set upright can be supported between the vertical roller bodies 8 facing each other (see FIG. 2).

Further, a horizontal roller body 7 is provided between a pair of vertical roller bodies 8 arranged side by side on the support frame 6 to form a corner roller 20 (see FIG. 3). When the corner roller 20 is used, in order to adapt the horizontal arm 3 to the angle of the corner of the cable rack P, the horizontal arm 3
Is formed to be bendable (see FIGS. 4 and 6).

Reference numeral 30 shown in FIG. 6 is a linear roller of the type mounted on the small beam P2. This straight roller 30
Has a horizontal roller body 7 provided on a frame 31 attached to the small beam P2, and a pair of vertical roller bodies 8 is erected at both ends of the horizontal roller body 7 (see FIG. 5). In particular, the spacing between the vertical roller bodies 8 is such that the flat cable Q1 can be supported in an upright state.

[0017]

The present invention achieves the original object by having the above-mentioned configuration. That is, according to the first aspect, the position of the roller on the cable rack can be freely selected by mounting the position adjusting rod 5 at an arbitrary position of the horizontal arm 3. Moreover, the roller can be easily mounted by simply assembling the support 1 and the horizontal arm 3 to the cable rack P.

Further, according to the second and third aspects, not only the round cable but also the flat cable Q1 can be supported, so that each portion of the cable rack P can widely support various kinds of cables.

As described above, according to the present invention, the attachment / detachment is easy and the position of the roller on the cable rack can be freely selected.
In addition, various industrially beneficial effects such as the ability to wire from flat cables to round cables can be achieved.
