Abstract

L'invention concerne un mécanisme de levage pour ascension comprenant un support-guide (100) et une tige d'amenée. Le procédé d'auto-ascension faisant intervenir le mécanisme de levage pour ascension est caractérisé en ce que, premièrement, lorsque le support-guide inférieur (100) a tendance à se déplacer vers le bas par rapport au rail (400) de guidage, ils sont tous deux maintenus bloqués. L'élément (200) d'actionnement de levage est ensuite avancé, ce qui déplace le support-guide supérieur (100) vers le haut par rapport au rail (400) de guidage. Plus tard, lorsque le support-guide inférieur (100) a tendance à se déplacer vers le haut par rapport au rail (400) de guidage, ils sont tous deux maintenus bloqués. Enfin, l'élément (200) d'actionnement de levage est rétracté, ce qui déplace le support-guide inférieur (100) vers le haut par rapport au rail (400) de guidage. Par une multiplicité d'itérations des étapes ci-dessus, la partie d'actionnement du mécanisme de levage pour ascension s'élève progressivement par rapport au rail (400) de guidage, réalisant l'auto-ascension du mécanisme de levage pour ascension.
