摘要
FIELD: transport.;SUBSTANCE: invention relates to laying electric cables between moving parts using take-up drum and may be used in electric loaders supplied from AC circuit. Proposed device comprises cable drum, ball-and-screw gearing, moving plate and compression spring. Cable drum has hollow hub accommodating nut of said gearing coupled with moving plate and compression spring. Said compression spring has one end engaged with hollow hub side surface and another end engaged with moving plate provided with sliding ledges to enter hollow nub lengthwise guide grooves. In compliance with first version, cable drum is mounted at screw of said ball-and-screw gearing while screw is rigidly secured on stationary support. In compliance with second version, cable drum is articulated with screw via coaxial reduction gearbox.;EFFECT: simplified modular design, higher reliability.;2 cl, 3 dwg
