Description

[Detailed Description of the Invention] The present invention relates to a cable fixing device for fixing bent portions of a cable laid in a tunnel or the like, such as an intermediate portion or a rising portion of the cable near the end of the cable.

Conventionally, cable fixing devices for fixing bent portions of large cables, such as electric power cables, consist of a pair of cleats that sandwich the electric power cable, and a shapeless cleat fixing base for fixing the cleats to a frame or the like. It has become.

However, the cables in the above-mentioned floor plan have complicated three-dimensional curves, and also have bending habits and twists unique to the cables, so it is necessary to individually design cable fixing devices suitable for such curves. In addition, the position of the cable fixing device must be adjusted to match the cable installation position and cable bending curve, and the cable fixing device must be installed on a frame, etc., which requires a large amount of effort to fix the cable. There was a drawback that it required a lot of work.

An object of the present invention is to provide a cable fixing device that can easily fix cables and is inexpensive.

In order to achieve this objective, the present invention provides a cable fixing device consisting of a cleat that clamps the cable and a cleat fixing base that fixes the cleat to a pedestal, etc. The cleat position adjustment mechanism is characterized in that it is provided with a vertical axis and a cleat position adjustment mechanism that supports the cleat so as to be rotatable about a horizontal axis perpendicular to the vertical axis within a vertical plane including the vertical axis.

Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, 1 is a cable, 2 is a cable termination portion attached to a frame or the like 3, and 4 is a cable fixing device according to the present invention.

The cleat fixing base 6 allows the cleat 5 to be rotated around a vertical axis A perpendicular to the axis of the cable 1 and a horizontal axis B perpendicular to the vertical axis A within a vertical plane including the vertical axis A, and in the vertical axis direction. The cleat position adjustment mechanism 7 is provided with a cleat position adjustment mechanism 7 that supports the cleat position so as to be extendable and retractable.

The cleat position adjustment mechanism 7 includes an intermediate flange disk 8, an outer sleeve 9 fixed to the center of the upper surface of the disk 8 by welding along the vertical axis A, and an outer sleeve 9 having an outer diameter smaller than the inner diameter of the sleeve 9. an inner sleeve 10 that is inserted into the sleeve 9 and is movable vertically and telescopically; and a fixing bolt 11 that is screwed onto the upper side wall of the outer sleeve 9 and fixes the inner sleeve 10 at a predetermined rotational position. , a U-shaped support piece 12 that opens downward and is fixed to the center of the lower part of the disc 8 by welding, a fixed support piece 13 that is fitted into the U-shaped groove 12', and a support piece 12 that penetrates both support pieces 12 and 13. U-shaped support piece 12
pin bolt 14 and fixing nut 1 that fixes the
It consists of 5.

This pin bolt 14 is provided within a vertical plane including the longitudinal axis A, passing through a horizontal axis B that is perpendicular to the longitudinal axis A and parallel to the cable axis.

Note that 16 indicates a cleat mounting plate fixed to the upper end of the inner sleeve 10 by welding, and 17 indicates a mounting plate to the pedestal etc. 3 fixed to the lower end of the fixed support piece 13 by welding.

The cleat 5 is fastened to the cleat mounting plate 16 of the cleat fixing base 6 by mounting bolts 18 and nuts 19, and is also fastened to the cable fixing base 6, etc. 3 by bolts (not shown).

When fixing the cable according to the cable bending curve, first fix the cleat fixing base 6 of the cable fixing device 4 to an appropriate position on the frame etc. 3 near the cable fixing position, and then use the cleat position adjustment mechanism. 7 fixing bolt 1
1 and align the inner sleeve 10, that is, the cleat 5 with the vertical axis A.
, rotate the cleat 5 by a desired angle and move it to a desired height, and loosen the fixing nut 15 to align the cleat 5 with the horizontal axis B.
The optimum position of the cleat 5 is then adjusted by loosening either the fixing bolt 11 or the fixing nut 15 depending on the position, etc., and then attaching the cable to this cleat 5. This is done by holding 1 and tightening it with mounting bolts 18 and nuts 19.

4 and 5 show other embodiments of the cleat fixing base 6, in which the cleat position adjustment mechanism 7 has an outer sleeve 9 attached to the center of the upper surface of the intermediate flange disk 8 so as to pass through the vertical axis A. A hexagonal nut 20 is inserted into the sleeve 9, and this is fixed to the snow by welding. A through bolt 21 with a cleat mounting plate 20 fixed to the upper end is screwed into the nut 20, and the hexagonal nut 20 is fixed in the vertical direction. After positioning the cleat (not shown) at the desired angle and height,
It is provided with a structure for tightening with a fixing nut 22, and the other structure is the same as that shown in FIGS. 3 and 4.

Using the adjustment mechanism of this embodiment is convenient because by loosening the fixing nut 22, the height of the cleat 5 and the rotation angle around the vertical axis A (that is, in the horizontal direction) can be adjusted at the same time.

In both of the above two embodiments, pin poles 1 to 14 are arranged in a vertical plane including the vertical axis A and passing through a horizontal axis B that is perpendicular to the vertical axis A and parallel to the cable axis. However, as shown in FIG. 6, pin poles 1-14 may be provided in a vertical plane including the longitudinal axis A, passing along a horizontal axis C that is perpendicular to the longitudinal axis A and orthogonal to the cable axis. .

Furthermore, the cleat position adjustment mechanism 7 shown in these embodiments is
Although the cleat 5 is provided with means for movable in the direction of the longitudinal axis A, that is, height adjustment means, the normally laid cable 1
Since the distance between the cleat 5 and the pedestal 3 can be manually changed to some extent, the height of the cleat 5 can be adjusted by interposing a spacer (not shown) of an appropriate thickness between the mounting plate 17 and the pedestal 3. Therefore, the height adjustment means may be omitted.

The cable fixing device according to the present invention has a cleat fixing base that fixes the cleat to a frame or the like. Since it is equipped with a cleat position adjustment mechanism that supports the cleat rotatably around the horizontal axis, even if the bending curve of the cable bending part varies, the cable fixing device can be individually designed and manufactured according to this. There is no need to do so, which saves time and effort, and the cable fixing device can be supplied cheaply and quickly.

In addition, there is no need for troublesome work management such as separating and storing fixing devices manufactured individually according to the cable installation situation, or selecting the necessary one from a large number of stored devices and using it for cable fixing. Cable fixing work can be carried out efficiently.

Furthermore, the cleat position adjustment mechanism supports the cleat so that it can rotate around the horizontal axis perpendicular to the vertical axis within a vertical plane including the vertical axis perpendicular to the axis of the cable, so the structure of the cleat fixing base is simple and It is miniaturized, the cable fixing device can be easily attached, and the labor required for cable fixing can be reduced.
