Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, a kind of high strength composite combination of power cable bearer, this support comprises column 1 and two support arms, described support arm comprises upper arm 2 and the side arm 3 that is connected respectively upper arm and column, also comprise fixture 4, fixture 4 is provided with four, be fixed between two on the upper arm 2 of two support arms, this fixture comprises upper clamp body 41, lower clamp body 42 and fixed base 43, described lower clamp body 42 is fixed on fixed base 43, upper clamp body 41 is bolted on lower clamp body 42, upper clamp body 41 and lower clamp body 42 are bolted and form a through hole matching with the outside diameter of cable, the large I of this through hole regulates by bolt, to adapt to the needs of various outer diameter cable, described fixed base 43 both sides are provided with locating slot 44, fixed groove 44 has certain length, therefore can adjust within the specific limits fixture horizontal position, by bolt, passing locating slot 44 is fixed on fixed base 43 on upper arm 2.
Described column 1 one sides are provided with draw-in groove 11, opposite side is provided with a plurality of positioning holes and a plurality of fixed hole, described support arm passes positioning hole by bolt and is fixed on column 1, and described draw-in groove 11 is fastened on the wall of cable to be installed, and by bolt, passes fixed hole column is fixed on wall.
