Description

Technical Field

[0001] The utility model relates to the technical field of lifting rings, and more specifically, to a movable lifting ring on a frequency conversion control cabinet. Background Art

[0002] During the manufacturing, installation, maintenance, or relocation of variable frequency control cabinets, their large size and weight may require the use of lifting equipment. The design of movable lifting rings makes the lifting process more convenient and quick. Simply connect the lifting rope or chain to the lifting ring to lift the variable frequency control cabinet safely and smoothly.

[0003] In existing public literature, patent publication number CN208617198U discloses a movable lifting ring device for a variable frequency control cabinet. The lifting ring fixing plate has a tail rope ring located in the center. The top of the variable frequency control cabinet is connected to the central axis via a swing bolt, making it easier for construction personnel to inspect and maintain the equipment. A gasket is also installed inside the top of the variable frequency control cabinet, significantly enhancing the secure connection between the variable frequency control cabinet and the central axis. This prevents the top of the variable frequency control cabinet from deforming due to external forces during transportation. This technology also has the following problems.

[0004] During the transportation of the frequency converter control cabinet, since the lifting rings are in fixed positions, it is difficult to ensure that each ring remains in the specified position during binding and transportation. This leads to inconsistent positions of the rings after the lifting rope contacts the rings, making it difficult to adjust the rings according to actual needs. This makes the lifting and use of the frequency converter control cabinet more time-consuming and labor-intensive, and its adjustability is poor. Utility Model Content
