According to the scheme, the problem that when different cables are arranged in the single-layer cable tray, the cables influence one another is solved, the problems that cables in a trench box are laid in a disorderly and unsystematic mode, and orderliness attractiveness is poor are solved, the cable tray can be conveniently used, and engineering design and construction installation are facilitated.
Description
Technical field
The present invention relates to a kind of support for cable, belong to the technical field of the support of cable.
Background technology
Cable testing bridge is divided into the structures such as slot type, pellet type and ladder-type, grid type, is made up of support, trailing arm and installation accessories etc.Whether all parts that should note crane span structure when type selecting meet seriation, generalization, standardized complete requirement.In building, crane span structure can independently set up, also can be attached on various buildings or structures and piping lane support, should embody simple in structure, handsome in appearance, flexible configuration and the feature such as easy to maintenance, all parts all need to carry out zinc-plated processing, are arranged on building outdoor crane span structure outward, if be close to seashore or belonging to corrosion region, material must have anticorrosion, moisture resistance gas, adhesive force is good, the physical property feature that impact strength is high.Crane span structure industry is restructuring and optimization constantly, and enterprise's crane span structure is shown one's talent, and surface treatment has cold galvanizing, hot galvanizing, electrostatic spraying, anti-lattice fire painting machine material, baking vanish etc.Wherein product is widely used in petrochemical industry, metallurgy, and electric power, school's communication, the fields such as skyscraper, have good looking appearance, and corrosion resistance is strong, and versatility is extensive, convenient and flexible installation, the features such as great variety of goods.For weight reduction can also adopt aluminium alloy cable and glass fiber reinforced plastic bridge, its overall dimension, load characteristic is all substantially close with steel crane span structure, due to aluminium, steel proportion difference (Al=2.7, Fe=7.86, calculate by weight, the ratio of aluminum steel is about 1:3, according to the market price conversion of two kinds of materials, the cost expense of aluminum cable tray will exceed 2.0 times than similar zinc-plated steel bridge valency, the advantages such as aluminum cable tray has attractive in appearance, lightweight, easy for installation, aluminum cable tray is applied in the engineering having.
Be limited by transformer station's cable interlayer floor height restriction, in cable interlayer, apply individual layer trough type bridge frame at present many.In intelligent substation, secondary cable is of a great variety, comprises lv power cable, control cables, optical cable etc., and in cable interlayer, they share individual layer trough type bridge frame.Because the cable of different voltage, different purposes should not be laid in same layer cable testing bridge, cause in current intelligent substation cable in secondary crane span structure to lay more disorderly and more unsystematic, neat appearance degree is poor, the construction while being unfavorable for maintenance after transformer station puts into operation and reorganization and expansion.
Summary of the invention
The technical problem to be solved in the present invention is, for prior art deficiency, propose a kind of subregion trough type bridge frame for transformer station's inside plant interlayer, this crane span structure can make individual layer trough type bridge frame lay inhomogeneity cable, thereby more effectively plans, lays the cable in secondary crane span structure.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of subregion trough type bridge frame for transformer station's inside plant interlayer, comprise and be fixed on the grooved bracing frame of transformer station's indoor roof and be arranged at the groove box in described grooved bracing frame, in described groove box, be provided with at least one and lay along crane span structure the dividing plate that direction is extended, groove box is divided into some regions by described dividing plate, in each region, be all interval with the anchor ear of fixed cable, described anchor ear and groove box are affixed.
The present invention adopts the beneficial effect of technique scheme to be: by some dividing plates are set in groove box, groove box is separated into some regions, and cable is laid in these regions, and fixes with anchor ear, individual layer trough type bridge frame can more effectively be planned in the time laying different cable, maintained easily.
The improvement of technique scheme is: grooved bracing frame comprises that one end and the roof of column are affixed along existing two row's column and the cross-arms that arrange in the laying direction of crane span structure, and the other end and the cross-arm of column are affixed.
The present invention adopts the beneficial effect of technique scheme to be: adopt the load-bearing mode of many columns, alleviate the pulling force being subject on single column.
The improvement of technique scheme is: also comprise the hoist cable arranging in pairs along in the laying direction of crane span structure, one end of every a pair of hoist cable is affixed with the two ends, left and right of cross-arm respectively, and the other end and the roof of hoist cable are affixed.
The present invention adopts the beneficial effect of technique scheme to be: hoist cable is shared the pulling force being subject on column, alleviates the pulling force that column is subject to, and makes cross-arm, and slot type bracing frame can bear heavier weight.
The improvement of technique scheme is: described groove box is that metal is made the also groove box of bonding, and described dividing plate is metal dividing plate, and described anchor ear is metal anchor ear.
The present invention adopts the beneficial effect of technique scheme to be: adopt metallic channel box, there is certain effectiveness groove box inside with respect to outside, in metallic channel box, establishes metal partion (metp), and making has effectiveness between regional.
The improvement of technique scheme is: described groove box is furnished with lid, described groove box inwall and diapire are provided with insulating barrier, described lid is the lid made of insulation material, the insulating barrier inwall of described groove box and described lid lower surface except with described dividing plate contact position equal coating electrically conductive paint.
The present invention adopts the beneficial effect of technique scheme to be: the zones of different of baffle for separating is made to relatively independent region, the inwall equipotential in each region, between each region, there is no conducting, improve capability of electromagnetic shielding between each region, make can lay dissimilar cable in the zones of different of individual layer trough type bridge frame, and dissimilar cable can not influence each other in the time of transmission.
