Description

Technical Field

[0001] This application relates to the field of cable winding and unwinding technology, and for example to a cable winding, unwinding, storage, and switching device. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] When drilling cluster wells, oil drilling rigs need to be moved back and forth to the designed position using a rig moving device before construction can begin. The mud purification system, electrical control system, mud pump set, etc., should be moved as little as possible to save time and drilling costs. Traditional cable management has the following problems: fixed cable lengths require repeated splicing and disassembly during movement, which is time-consuming and can easily damage the joints; temporary cable laying is susceptible to crushing and corrosion, posing safety hazards; and when not moved, cables are piled up haphazardly, taking up space and making rapid deployment difficult. Summary of the Invention

[0004] This application provides a cable winding, storage, and transfer device, which combines an electric winch and a pulley to achieve one-button operation. When pulled out, the limiting rope restricts the maximum distance between adjacent pulleys, so that adjacent pulleys are connected in series through the limiting rope and move together, while preventing the cable from being overstretched and protecting the cable.

[0005] A cable storage and transfer device includes: a cable storage transfer frame, a first guide rail, multiple trolleys, a limiting rope, a suspension frame, multiple extension frames, an electric winch, a traction rope, and a guide pulley;

[0006] Cable storage adapter rack, which stores cables inside;

[0007] The first guide rail is fixedly installed inside the cable storage adapter rack;

[0008] Multiple trolleys are sequentially arranged on the first guide rail and move along the extension direction of the first guide rail;
