The utility model discloses the technical scheme who further injects does:

the inner rail, the middle rail and the outer rail are sequentially coated from inside to outside of the guide rail, and two adjacent rails are connected through a ball mechanism, so that the two adjacent rails can slide mutually.

The diameter of the telescopic outer rod is larger than that of the sleeve.

The width of aforementioned apron is greater than the width of cable duct to set up the fixture block in apron bottom both sides.

And the outward flanging at the upper end of the side plate is provided with a clamping groove larger than the clamping block.

The bottom plate is at least provided with 2 groups of partition plates, and the number of each group of partition plates is 2-4.

The cover plate is provided with a heat dissipation opening, and a dust screen is arranged in the heat dissipation opening.

The reinforcing ribs are arranged in the cable grooves.

Aforesaid cable duct and apron are the aluminum alloy material to the surface of crane span structure body and apron is evenly scribbled fireproof paint layer.

The utility model has the advantages that: the cable bridge frame has a simple structure, can realize the opening and closing of the cover plate by arranging the electric telescopic rod, has high flexibility, does not need to be disassembled, ensures that workers can conveniently maintain the cables, saves time and labor, is at least provided with 2 groups of clapboards on the bottom plate, has 2-4 clapboards in each group, is favorable for separating and arranging the cables, avoids the cables from being interlaced and wound together due to excessive quantity, and is convenient for the operators to overhaul and replace; the cover plate is provided with the heat dissipation port, so that heat in the cable bridge can be effectively dissipated, the temperature is reduced, the normal work of the cable is guaranteed, the aging of a cable core caused by heat is slowed down, and the service life is prolonged; the dustproof net is arranged at the heat dissipation port, so that the entering of dust can be effectively reduced; the reinforcing ribs are welded in the cable bridge main body, so that the strength of the cable bridge can be effectively improved; a fireproof paint layer is sprayed on the outer surfaces of the bridge groove and the cover plate, so that the effects of fire retardance and isolation can be achieved.
