Description

Technical Field

[0001] The utility model belongs to the technical field of induction furnace pushing equipment, in particular to a multifunctional hydraulic vehicle used for pushing out the lining of an induction furnace. Background Art

[0002] As the equipment level continues to improve, some existing large-tonnage induction furnace linings need to be completely dismantled and rebuilt in the later stage. The current conventional manual dismantling cannot meet the production rhythm requirements and is highly dangerous. Induction furnace equipment requires a lining hydraulic push-out mechanism.

[0003] The traditional design of the lining push cylinder is:

[0004] 1. The lining push-out hydraulic system is shared with other hydraulic systems and needs to be connected to the push-out cylinder through a longer pipeline;

[0005] 2. The oil cylinder is placed offline separately. When in use, it is hoisted to the oil cylinder connection seat on the furnace body by a workshop crane, and then the furnace lining is pushed out. During the pushing out process, in order to ensure that the oil cylinder is level, the crane still needs to hold the oil cylinder.

[0006] 3. Some equipment layout areas are not equipped with cranes, so the lining ejection operation cannot be carried out; even if a crane is equipped, it is difficult to accurately position the cylinder due to the hook, making it very difficult to dock the cylinder with the cylinder connection seat. Moreover, it is difficult to ensure the verticality of the cylinder and the lining ejection block when the cylinder is lifted by the crane for ejection operation, and the cylinder piston rod is often deformed due to the tilt of the cylinder under force.
