Description

Technical Field

[0001] The utility model belongs to the technical field of equipment related to reactor installation, and in particular relates to a lifting device for a reactor. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with electricity is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron-core reactor.

[0003] When installing or operating the reactor, the height needs to be adjusted in stages. Generally, cranes and other equipment are used for lifting. However, cranes cannot enter the room to lift the reactor. In addition, the lifting operation of the reactor needs to last for a long time. Cranes and other equipment are large. The reactor lifted by the crane is prone to shaking, which poses a safety hazard. In addition, cranes and other equipment occupy a large area, affecting the operating space of other machinery.
