Abstract

The invention provides a ladle turret lifting device. Lifting frames are installed on the two sides of a turret. Guide wheels are installed on the lifting frames. A guide plate is perpendicularly welded to the turret. The guide wheels roll up and down along the guide plate. When the lifting frames rise or fall, the guide wheels installed on the lifting frames roll up and down along the guide plate, so that a stable guiding effect is achieved; the lifting frames are driven by lifting hydraulic cylinders to rise and fall; and spherical thrust bearings are installed between the lifting frames and the lifting hydraulic cylinders. The spherical thrust bearings have a self-centering function so that the effect that cylinder rods do not bear radial force can be guaranteed. When the lifting hydraulic cylinders drive the lifting frames to rise and fall, the guide wheels roll along the guide plate for guiding in the casting direction, namely the x direction; sliding plates slide along the guide plate for guiding in the direction perpendicular to the casting direction, namely the y direction; the lifting frames can be vertically hoisted to be disassembled and assembled; and the structure is simple, and installation and maintenance are easy.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a lifting device for a ladle turret. Background technique [0002] The ladle turret of continuous casting machine is the molten steel transfer equipment between steelmaking and continuous casting. The empty ladle of molten steel is transferred to the receiving position for transfer. [0003] At present, the ladle turret adopts a four-link lifting mechanism, and there are many large structural parts, which are connected by pin shafts. The rotating pair uses a large number of joint bearings, which increases the cost of equipment. The molten steel transfer equipment between castings is often arranged on the common axis of the steelmaking span and pouring span of the plant. The equipment is located in the dead corner of the crane and is not easy to install and maintain. Contents of the invention [0004] The purpose of the present invention is to solve...
