Wheel tensioner for tensioning facilities power cables and wires in an installation support overhead power line catenary.

摘要

Tensioner wheel facilities retensioning power cables and cable support unainstalación overhead power line catenary - with a wheel tensioner wheel (4) having a drum higher (5) diameter and a drum dediámetro lower (6), - and with at least one retaining element (9) which cooperates with at least one locking toothing (7, 8) which estádispuesto in the drum of larger diameter (5), wherein - respectively at least one locking toothing (6, 7) with tapered corrugated profile is arranged on the outer dosflancos drum larger diameter (5), - and in that the retaining element (9) collaborates, in the case of failure, symmetrically with jagged deretención (6, 7), - that through the engagement of the locking toothing (7, 8) in the retaining element (9) is carried out unfrenado performed through friction wheel tensioner wheel (4) and, as soon as the bottom tooth locking toothing (7, 8) falls into the holding element (9) takes place by uniónpositiva conditional fixing wheel tensioner wheel (4).
