Abstract

The invention provides a method for replacing a whole large-ladle revolving platform when an upper lifting space is limited, which can quickly replace a revolving bearing and a pedestal and has higher safety, short construction period and lower construction cost. The method comprises the following steps: making a shoulder-pole beam pass through the upper middle of the revolving platform, and using two hooks of an overhead crane to hook both ends of the shoulder-pole beam; filling cushion blocks on upper parts of connecting rod holes for connecting rods to pass through on a box body, and making upper parts of the connecting rods contact the bottoms of the cushion blocks; taking four connecting rods on the upper part of the revolving platform as suspension centers, and using suspension bands to bundle the four connecting rods and the shoulder-pole beam; lifting the shoulder-pole beam, making a revolving body above the revolving bearing lifted for a certain distance along with the shoulder-pole beam, horizontally moving the shoulder-pole beam, and driving the revolving body to be deviated from an axial line of the revolving platform; using a hanger to lift away the prior revolving bearing and the prior pedestal, and placing a novel revolving bearing and a novel pedestal; and assembling the revolving body.

Description

technical field

[0001] The invention relates to a method for integrally replacing a bale turntable with limited hoisting space above, and belongs to the field of installation and construction of metallurgical machinery and equipment. Background technique

[0002] Thin slab continuous casting and rolling ladle turret is mainly composed of base, slewing bearing, slewing body, ladle arm, connecting rod, lifting hydraulic cylinder, etc. It is the supporting and carrying equipment for ladle. Its function is to turn the fully loaded steel ladle located at the receiving position to the steel pouring position, ready for pouring, and at the same time turn the poured empty ladle back to the ladle receiving position. The slewing bearing is located between the base and the slewing body, and is an important equipment of the bale turntable.

[0003] The ladle turntable of Meishan Steelmaking 2# machine was put into production in October 2002. The slewing bearing was replaced in April 200...
