Description
Technical field
The present invention relates to a kind of terraced Guang more particularly to a kind of horizontal bar for ladder type cable trays.
Background technique
Cable testing bridge is extensive in industrial applications such as petroleum, chemical industry, electric power, light industrys, is mainly used for empty power cable, control
The laying of cable, illuminating line, telecommunication cable, it is more demanding for intensity, the bearing capacity of gantry.Gantry includes terraced side, ladder
Guang, the ladder side are integrally fixed with terraced Guang, generally use the cross sectional shape of change cable bridge ladder side profile to improve gantry
Intensity, bearing capacity and bending resistance.
Since ladder-type bridge frame mechanical robustness is weaker relative to pallet gantry, and its terraced Guang and the connection type on terraced side are general
It is connected for, therefore its stability, shock resistance, bearing capacity are all bad.
Summary of the invention
The present invention proposes a kind of horizontal bar for ladder type cable trays regarding to the issue above, and mounting stability is good, multiple carrying, more
Safety.
Specific technical solution is as follows:
A kind of horizontal bar for ladder type cable trays, including top rail, connecting rail and bottom rail, top rail are horizontally staggered with bottom rail
Setting, connecting rail is inclined to be fixed between top rail and bottom rail, and the angle a between connecting rail and top rail is 100-
105 °, a hex nut is welded and fixed in the two sides of top rail, connecting rail and bottom rail respectively, and hex nut is used for will be terraced
Guang is fixed on gantry.
A kind of above-mentioned horizontal bar for ladder type cable trays, wherein if the top rail and bottom rail include first rectangular frame and
Dry first partition, it is opposite on the inner wall of first rectangular frame to be equipped with first sliding groove, first partition include first partition main body and
The end plate at first partition main body both ends is set, and two end plates are slidably disposed in two first sliding grooves, first partition master
The two sides of body, which protrude outward, to be a circular-arc structure, and the height h1 of first partition main body is greater than the thickness h 2 of first rectangular frame.
A kind of above-mentioned horizontal bar for ladder type cable trays, wherein the connecting rail include second rectangular frame and several second every
Plate, opposite on the inner wall of second rectangular frame to be equipped with second sliding slot, second partition is slidably disposed in two second sliding slots
Between, the height h3 of second partition is less than the thickness h 4 of second rectangular frame.
Above-mentioned a kind of horizontal bar for ladder type cable trays, wherein the first partition is equipped with several heat release holes.
The invention has the benefit that
Terraced Guang of the invention is fixed between two side plates of gantry by hex nut, in first partition and second partition
Compartmentation under, two groups of cables can be carried simultaneously, mounting structure of the present invention is stablized, and utilization rate greatly improved, and saves
Efficiency, good heat dissipation effect, securely and reliably.
