Title (EN) SYSTEM AND METHOD FOR INSTALLING A TENSIONING TENDON IN A WIND TURBINE TOWER
(FR) SYSTÈME ET PROCÉDÉ D'INSTALLATION D'UN TENDON DE SERRAGE DANS UNE TOUR ÉOLIENNE
Abstract:
(EN) A system and method for installing a post-tensioning tendon (130) in an equipment tower (100). A sheave frame (196) attaches to anchor rods (140), and a pulley (198) is mounted to the sheave frame through which a hoisting cable (197) is passed for connection to an end (138) of the tendon to lift the tendon to the anchor rods. A carriage assembly (150) having a shank (152) and a bearing plate platform (154) extending transversely from the shank for receiving a bearing plate (170) is attached to the tendon. The carriage assembly includes a deflecting surface (158) to deflect the carriage assembly away from the installed bearing plate upon lowering after tendon attachment. A pair of hydraulic jacks (210) tension the tendon to a desired load.
(FR) L'invention concerne un système et un procédé d'installation d'un tendon de post-serrage (130) dans une tour d'équipement (100). Un cadre de poulie (196) s'attache à des tiges d'ancrage (140), et une poulie (198) est montée sur le cadre de poulie à travers lequel un câble de levage (197) est passé pour un raccordement à une extrémité (138) du tendon pour soulever le tendon vers les tiges d'ancrage. Un ensemble chariot (150), ayant une dent (152) et une plate-forme de plaque d'appui (154) s'étendant transversalement depuis la dent pour recevoir une plaque d'appui (170), est fixé sur le tendon. L'ensemble chariot comprend une surface de déviation (158) pour dévier l'ensemble chariot à l'opposé de la plaque d'appui installée lors de l'abaissement après la fixation de tendon. Une paire de vérins hydrauliques (210) serrent le tendon à une charge souhaitée.
