Abstract

The invention provides a jacking device and method for replacing a steel ladle rotating disc bearing and belongs to the technical field of continuous casting machine steel ladle rotation table maintenance equipment. The jacking device and the method are used for replacing the steel ladle rotating disc bearing of a steel ladle rotation table fast. According to the technical scheme, a replacing toolcomposed of jacking hydraulic devices, a sliding support and a locating device is utilized for replacing the steel ladle rotating disc bearing. The same four jacking hydraulic devices jack the steelladle rotation table synchronously, an old steel ladle rotating disc bearing is disassembled and moved out by means of the sliding support, the new steel ladle rotating disc bearing is moved in and installed, and the locating device ensures accurate location of the steel ladle rotation table and the steel ladle rotating disc bearing. According to the device and the method, the problems that the steel ladle rotating disc bearing is complex to replace, and deviation rectifying is difficult are solved, the steel ladle rotating disc bearing of the steel ladle rotation table can be replaced fast and efficiently, the maintenance operation time is shortened substantially, the construction working efficiency is improved, the labor intensity of workers is reduced, the installing precision of the steel ladle rotating disc bearing is improved remarkably, and the security risk in the replacing process is reduced.

Description

technical field

[0001] The invention relates to a proportional jacking and sliding device and method for replacing a ladle turntable bearing of a ladle turntable, and belongs to the technical field of maintenance equipment and methods for a ladle turntable of a continuous casting machine. Background technique

[0002] The ladle turret is currently the most widely used ladle support and carrying equipment in continuous casting machines. It has multiple functions such as rotation, lifting, weighing of molten steel, locking, and ladle capping and heat preservation. The main function is to receive a full ladle of molten steel, transfer the molten steel from the steel delivery span to the casting span of the continuous casting machine through the rotation of the ladle turret, inject the molten steel in the ladle into the tundish, and return the poured empty ladle to the steel delivery across, so that the crane can be transported away, so as to realize the continuous pouring of mu...
