Embodiment 1
[0014] A CDQ cable bridge installation method, including the steps of measuring and positioning, installing metal expansion bolts, installing brackets and hangers, installing bridges, and grounding protection. The specific steps are:
[0015] When measuring and positioning, find a horizontal or vertical line from the beginning to the end, determine and mark the specific position of the support;
[0016] When the bracket and the hanger are installed, the bracket and the hanger shall be made of straight, non-distorted steel. After cutting the material, the length deviation shall be within 5mm. Deformation, uniform welding seams; the material specifications of the bracket and hanger are: angle steel L40mm×40mm×4mm, the diameter of the boom is 10mm; the distance between the brackets installed horizontally on the cable bridge is 1.5-3m, and the distance between the brackets installed vertically is no more than 2m. The spacing of the brackets in the same area shall be consistent, an...

The invention relates to a method for installing a coke dry quenching cable bridge bracket, belonging to the field of the electrical equipment installation. The method for installing the coke dry quenching cable bridge bracket comprises the steps of measuring, positioning, installing metal expansion bolts, installing a support and a hanging bracket, installing a bridge bracket, can carrying out grounding protection. The method for installing the coke dry quenching cable bridge bracket is characterized in that in the step of measuring and positioning, a horizontal line or vertical line is found from the starting end to the stopping end, and the specific position of a supporting article is determined and marked; in the step of installing the support and the hanging bracket, the straight 40 mm * 40 mm * 4 mm angle steel L which is not twisted in used for making the support and the hanging bracket which has the diameter of 10 mm, the straight steel is cut with the length deviation being controlled within 5 mm and no curled edges and burrs being found on the incisions, the support and the hanging bracket are arranged and fixed horizontally in the latitudinal direction and vertically in the longitudinal direction with no obvious deformation being found, and the welding seams are kept uniform and even. Adopting the steps of strictly measuring, positioning, installing the support and the hanging bracket, and installing the bridge bracket, the method for installing the coke dry quenching cable bridge bracket is easy to operate, is safe and reliable and has excellent electrical performance.
Description
technical field [0001] The invention relates to the field of electrical equipment installation, in particular to a CDQ cable bridge installation method. Background technique [0002] Dry coke quenching is a newly born smelting energy-saving technology in the world. Its English name is Coke Dry Quenching, or CDQ for short. CDQ uses circulating inert gas as the heat carrier, and the circulating fan sends the cold circulating gas into the red coke cooling chamber to cool the high-temperature coke to below 250°C and discharge it. The circulating hot gas after absorbing the heat of coke is introduced into the waste heat boiler to recover heat and generate steam. After the circulating gas is cooled and dedusted, it returns to the cooling room through the fan, so that the red coke is cooled in this way. The steam generated by the CDQ boiler is either integrated into the steam pipe network in the plant or sent to generate electricity. Dry coke quenching technology is a major ener...
