In addition, because the length of the factory building is more than 300 meters, in order to solve the problem of long-distance voltage drop, a large number of compensation cables are designed, and the cables are required to be laid in a cable bridge frame below the travelling crane beam. The cross section of a travelling beam of a metallurgical plant is very large, the beam is 2m high if the cross section is very large, and the beam is more than 4m high if the cross section is very large, and a bridge route cannot be arranged among a bridge, a power cabinet and a trolley line power supply section, so that the direct force of a cable on a wiring terminal of the equipment is very large, and the loosening of the wiring terminal and the fatigue damage of the cable are easily caused after a period of time, thereby causing electrical safety accidents; meanwhile, the cable is disordered in suspension, free of fixation and poor in appearance quality. The cable bridge route arranged below the travelling beam cannot be installed due to the fact that the space between rib plates for installing the bridge stand columns is too large, and welding operation is not allowed in other areas except the rib plates on the travelling beam.
The mounting distance of the cable bridge stand column under the travelling beam can not meet the requirements of specification and design, the rib plate distance of the bridge stand column which can be welded under the travelling beam is more than 2.5m, and the mounting point of the bridge stand column can not meet the requirements of the design and specification specified distance.

Includes 2 routes:
route 1: a cable bridge under the travelling beam-a power supply cabinet on the travelling beam walkway plate;
route 2: a power supply cabinet on the travelling beam walkway plate, namely a power supply end on the sliding contact line side of the travelling beam.
The existing cabling rack technology generally adopts a cable bridge rack to realize the laying route of cables, the cable bridge rack consists of bridge rack upright columns (I-shaped steel or angle steel upright columns), bridge rack supporting arms, a bridge rack (step type or tray type) and installation connecting accessories thereof, the metallurgical industry factory building mostly adopts the bridge rack made of hot galvanized steel, the weight of the upright columns and the supporting arms is large, the bridge rack is 2 m/piece, and the material is transported to an installation point, which wastes labor and time.
The existing installation technology of the cabling rack (cable bridge) adopts a field assembly mode, a plurality of connecting and installing accessories are provided, the adjustment of quality control indexes such as the verticality of an upright post, the levelness of a supporting arm of the cable bridge, the centrality of the cable bridge and the like takes labor and time, and the difficulty of the quality control of the cable bridge installation is high.
(1) The control difficulty of welding verticality on the bridge stand column (I-steel stand column or angle steel stand column) on the rib plate of the travelling beam is high, and the efficiency of construction operation is low;
(2) the bracket arm is arranged and fixed on the bridge stand column, and the levelness adjustment workload is large, which wastes labor and time;
(3) the bridge is fixed on the bracket arm by a ladder frame pressing plate, and the center degree of the bridge is difficult to adjust.
