Description

Technical Field

[0001] The utility model relates to the technical field of artificial lifting, in particular to a heavy-load retractable machine for a steel wire power cable. Background Art

[0002] In the artificial lifting industry, the use of steel wire power cable casting and catching mode can greatly increase the speed of lowering and lifting the submersible electric pump into the well. The steel wire power cable is used to suspend the weight of the entire unit. The entire operation process does not require the intervention of a well repair rig, reducing the cost of well repair. Conventional retractors have a low load-bearing capacity. At the same time, conventional retractors generally have only one or two brake protections, which cannot meet the needs of power cable casting and catching to ensure the inherent safety of the wellhead; conventional retractors above 30t are large in size and cannot meet the needs of container shipping. On unmanned platforms, the heavy weight of the retractors makes hoisting inconvenient; for some platforms that cannot be welded and fixed with bolts, conventional retractors are inconvenient to operate and difficult to fix.
