A wire rope winding and unwinding management device for a double-steel-cable suspension hoisting mechanism
By designing a forced cable routing system with a spiral groove and a double-headed fork in the double cable lifting mechanism, combined with the tensioning mechanism of the rubber drive wheel, the problems of cable tangling, overlapping, and jumping in the groove under no-load conditions are solved, achieving high reliability and low wear cable winding and unwinding, which is suitable for the aerospace field.

AI Technical Summary
Existing dual-cable lifting mechanisms cannot be properly deployed or retracted under no-load or light-load conditions. They suffer from messy cable arrangement, complex structure, and easy wear. Furthermore, they are prone to problems such as tangled cables, overlapping cables, and cable slippage, making it difficult to meet the compactness and lightweight requirements of the aerospace industry.
A forced cable laying closed-loop control system is constructed by using a drum with helical grooves that rotate in opposite directions and a double-headed shift fork that spans the drive shaft and positioning shaft. The synchronous winding and unwinding of the steel cable is achieved through the rubber drive wheel and gear transmission, and the tension is provided by the elastic deformation and speed difference of the rubber drive wheel.
Under no-load or light-load conditions, the steel cable is wound and deployed in an orderly manner, which improves the reliability and synchronization of winding and deployment, reduces wear, and has a compact and lightweight structure, making it suitable for harsh aerospace environments and meeting the safety and reliability requirements of equipment.
