Design and tension control of double drum Winch system for deep-sea exploration equipment

Abstract

This paper puts forward the structure scheme of dual winch with separation of storage and a traction mechanism. In view of the problems about the existing cable arrangement of single drum winch retracting long deep-sea detector cable where the tension is uneven. Whereas the traction winch with double drum structure, composed of two parallel groove drums, two drums driving at the same time. The cable winding in order on two drums. According to the deep water monitoring specific tasks, for different parts of the system to carry out the design and calculation, the scheme satisfies the requirements of deep water monitoring, achieves the design aim to control tension and extend the service life of the cable..

Automated Cable Preparation for Robotized Stator Cable Winding

“…The smoothness and uniformity of the prepared cable end should then be inspected. order to decide the cable tension, as in [14]. However, the best solution would probably be to combine cable tensing equipment and cable tension supervision with an additional motor driving the cable drum, similar to how it is done in [16].…”

“…A similar simple but more controlled cable tensing equipment solution is to guide the cable horizontally between three line wheels, where the cable is guided over the middle line wheel which is mounted above the other two line wheels and vertically springy downwards. In this way, the damping of the middle wheel can be supervised in order to decide the cable tension, as in [14]. However, the best solution would probably be to combine cable tensing equipment and cable tension supervision with an additional motor driving the cable drum, similar to how it is done in [16].…”

“…In particular, the robotized cable winding application requires precise cable feeding lengths with a fast, synchronized and fully integrated control as well as a precise delivery of the cable to the robots. Other applications with some similarities are automatic cable winches for remotely operated or autonomous sub-sea vehicles and automated filament winding systems [14][15][16]. However, neither of these solutions could be used directly for this application.…”

“…Machines 2017, 5, 14 2 of 23 [3,12,13]. The most recent such robot cell prototype [13] included equipment for automatic cable feeding from a small cable drum to two industrial robots, equipped with cable feeder tools, to wind a short UU WEC stator, see Figure 2a.…”

Highly Repeatable Rope Winch Design With Multiple Windings and Differential Gear Mechanism

“…A double-drum winch uses two grooved drums to prevent sideways slip [14]. The payload determines the rope tension of the load and the tension of the free end.…”
