Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for securing at least one cable, pipe or other elongate member to a support and/or for securing two or more cables, pipes or other elongate members. For convenience, the following members are included in the term "cable".

To install single-core power cables in the cable network of an industrial facility, three single-core power cables are usually arranged side by side with an axis passing through the apex of a triangle in an arrangement called a three-core cable group. is common. Three-conductor cable groups are typically secured to the cable ladder by cleats, and in the spaces between the cleats, the groups of cables are secured together with cable straps or cable ties. This arrangement has the disadvantage that cable straps and cleats of different thicknesses must be used for cables of different thicknesses.

The object of the invention is to provide a device for fixing at least one cable to a support or for fixing two or more cables together, which device can be adapted to a fairly wide range of cable thicknesses. It is something.

According to the invention, the device includes a base member having two sloped surfaces on which one or two cables rest, and a distance between the slopes from the base member that extends along the length of the one or more cables. a rod extending and secured to the base member; a band passing around the rod and the cable(s) at least once; Tensioning means are included to secure the cables together or to secure the cable or cables to the base member.

Preferably, the base member with the two inclined surfaces and the rod through which the band passes are integral.

The inclined surface may be made of one arcuate surface or two arcuate surfaces, but preferably two plane surfaces. It is also good if the bar surface is sloped.

When the device is used to secure two or more cables (as occurs, for example, when power cables are subjected to high levels of short-circuit current), one or more cables may be Preferably, the strap is passed around the rod and cable at least twice to prevent the strap from tearing within the cable.

The band should be made of stainless steel.

The base member is often made of cast metal or metal alloy;
Preferably, it can be fixed to a cable ladder or other support surface.

The tensioning means comprises a plate having upright walls at both ends so that the strip can pass between the walls, a rod having a longitudinally extending slit and rotatably attached to an aligned hole in the upright wall of the plate, and a rod. The rod is provided with locking means capable of preventing rotation of the rod when properly placed in the hole. This arrangement is such that, in use, one end of the strap of the fixation device is fixed (e.g. by welding) to a plate, and the strap is wrapped once or several times around the cable or cables that are fixed to the rod of the fixation device. After the rods are placed in the holes in the upright walls of the board, the tips of the strips are passed through the slits of the rotating rods, and the rods are rotated to thread the strips around the rods and the cable or cables. taut and locking means are used to further prevent rotation of the rod (tightening or loosening the band).

The plate should be made of stainless steel.

The rod is preferably a stainless steel split pin.
In this case, the locking means preferably comprises a lock which fits into the eye of the cotter pin and is used to assist the rotation of the cotter pin, and the upright walls of the plate are provided with aligned holes so that the lock can be secured after rotation of the cotter pin. It is best to prevent further rotation of the cotter pin by rotating and fitting into aligned slots.

This device is used to secure one or more cables to a supporting surface or to secure a number of cables together, and the four times the thickness of this device is at least 33 times the thickness of known cleats. It can accommodate a wider range of cable thicknesses than the known cleats that it replaces.

The invention will be described by way of example with reference to the accompanying drawings, in which: FIG.

1 and 2, a device 1 for fixing three cables 2 together and for fixing the cables to a support (not shown) has two inclined surfaces 4, 5 on which the two cables rest. It comprises a base member 3 and a rod 6 with a central arm of a substantially U-shaped member 7 secured to the base member 3 by a split pin 8, the rod 6 extending from the base member 3 between the inclined surfaces 4, 5. They are spaced apart and extend in the length direction of the cable 2. The cable 2 is secured with a stainless steel strap 9 passing around the cable and rod 6, the strap being tensioned with a rotating split pin device 10 (described in more detail below). The base member 3 is fixed with bolts 11 to a support (for example a cable ladder).

A similar arrangement is shown in FIGS. 3 and 4, in which the device 12 includes a base member 13, a rod 14 with a central arm of a U-bolt 15 secured to the base member 13, and a stainless steel steel strip 16;
Equipped with tensioning means (excluded for simplicity). Additionally, tension is provided to adjust the nut 17 of the U-bolt 15.

A third example arrangement is shown in FIGS. 5-9. This example comprises a base member 19 integral with the bar 20, both having inclined surfaces 21, 22, stainless steel strips 23, 23' and tensioning means (omitted for simplicity). An adapter 24 is also shown, which fixes the base member 19 to a support (not shown) with a single bolt 25, and is installed before the cable is properly fixed. This is done through hole 26. Without this adapter, the base member 19 would be secured with the bolt holes 27 in the usual manner. adapter 24
The hooks 28 fit into one of the bolt holes to prevent sliding when the device is mounted vertically.

The possible range of such a device is highlighted in FIG. This shows how to secure three cables 29 of a certain thickness, and how to secure three even thicker cables 29' using the same device.

Certain types of tensioning means are shown in Figures 10 to 14 below.
The figure is described. The tensioning means 10 comprises a stainless steel plate 30 with upright walls 31 at both ends, between which the strip 9 passes. The rods are in the form of stainless steel split pins 32 that are rotationally secured into alignment holes 33 in the upright walls 31 of the plate 30. In this arrangement, one end 34 of the strip 39 is welded to the central portion 35 of the plate 30. The tip 36 of the band 9 is the cable 2 to be fixed.
and around the rod of the device 1 (not visible in FIG. 10) and through the crack in the split pin 32. Split pin 3
Rotating the cable 2 wraps the band 9 around the split pin and tightens the band around the cable 2. The locking means is provided by a lock 37, which has the eye 38 of the split pin 32.
A matching slot 39 in the upright wall 31 of the plate 30 is used to assist in rotating the split pin.
is rotated into engagement with the cotter pin to secure the split pin.

This tensioning means is also shown in Figures 3 and 4, as well as in Figure 5.
It is also used in the examples shown in FIGS.
