step five: if the main lifting balance frame (11) is arranged on the body of the main trolley (16), the thin hoisting steel wire rope (14) wound on the steel wire rope disc (2) sequentially passes through the ground slider (15) and the trolley body slider (9), the steel wire rope disc device (3) is driven to drive the thin hoisting rope (14), the new steel wire rope tail rope (102) is lifted to the body of the main trolley (16), and the pin shaft (17) and the main lifting balance frame (11) are fixedly installed;
step six: operating the main hoisting mechanism of the liquid metallurgy crane, slowly winding a new steel wire rope (1) onto a main hoisting drum (7), and lifting a plate hook cross beam (5) to complete the replacement of the new steel wire rope (1); the old steel wire rope (8) is also coiled on the steel wire rope coiling device (3).
6. The replacement method of the replacement structure of the single steel wire rope of the metallurgical crane according to claim 5, wherein the replacement method comprises the following steps: the fifth step is as follows: if the main lifting balance frame (11) is arranged on the plate hook cross beam (5), the liquid metallurgy lifting main lifting mechanism is directly operated to slowly lift the tail rope (102) of the new steel wire rope (1) to the height of the main lifting balance frame (11), and the pin shaft (17) and the main lifting balance frame (11) are fixedly installed.
