Abstract

La présente invention concerne un mât de distribution et un dispositif de hissage de machinerie de construction. Le dispositif de hissage comprend un montant vertical, un premier cadre (100), un second cadre (200) et un mécanisme d'entraînement. Le premier cadre (100) ou le second cadre (200) est fixé au montant vertical. Le mécanisme d'entraînement comprend un dispositif d'actionnement (310) qui est relié au premier cadre (100) et au second cadre (200) à ses extrémités, respectivement. Le premier cadre (100) et le second cadre (200) sont installés par ajustement coulissant dans la direction verticale. Dans l'état de dépliage, la hauteur du corps de cadre qui est formé par le premier cadre (100) et le second cadre (200) est supérieure à la hauteur d'un étage. L'extension du dispositif d'actionnement (310) peut entraîner le déplacement du premier cadre (100) et du second cadre (200) vers le haut et vers le bas, par rapport à l'étage prédéfini, progressivement, l'un sur l'autre, et peut entraîner le levage ou l'abaissement du montant vertical, afin de réaliser le hissage et l'abaissement progressifs de la machinerie de construction. Le mécanisme d'entraînement s'élève conjointement avec le hissage de la machinerie de construction en utilisant le dispositif de hissage de machinerie de construction. Il est inutile d'actionner individuellement le mécanisme d'entraînement du dispositif de hissage de machinerie de construction, ce qui simplifie le procédé de hissage de la machinerie de construction et améliore l'efficacité du hissage.
