BLOCK-TYPE AERIAL WORK PLATFORM FACILITATING HEIGHT ADJUSTMENT

The present invention comprises: a moving means (10) provided as a square frame (100) having rollers (101) mounted thereon so as to be movable to a work position; a platform (20) that an operator boards to perform high-place work; and a lift means (30) foldably provided between the moving means (10) and the platform (20) so as to lift/lower the platform (20), wherein the lift means (30) includes a plurality of block-type lift means (300) that are detachably stacked, each of which has fixing frames (310) provided at both the upper and lower sides thereof and has a plurality of lift arms (340) of which both end portions and the middle portion are rotatably connected to each other by means of rotating pins (341) between the fixing frames (310), and the moving means (10) includes: a fixing bar (110) having one side fixedly coupled to the rotating pin (341) provided in the center of the X-shaped lift arm (340) provided at the lowest block-type lift means (300); a lift bar (120) fixedly coupled to the other side of the fixing bar (110), and having an elongated hole (121) formed therethrough; a connecting bar (130) which has a pin (131) that is provided on one side thereof and slides along the elongated hole (121), and which has the other side fixedly coupled to a horizontal rod (140); horizontal rods (140) which are fixedly coupled to be elongated at each predetermined position between both sides, facing each other, of the frame (100) and which protrude to the outside of the sides, facing each other, of the frame (100) so as to be fixedly coupled to respective support bars (150); and the support bar (150) having one end fixedly coupled to the horizontal rod (140) and having the other end at which a mounting part (154), which has a rotating handle (151) penetratively coupled to the upper end thereof and has, at the lower end thereof, a mounting rod (153) having a contact plate (152), is provided. La présente invention comporte: un moyen (10) de déplacement réalisé comme un cadre rectangulaire (100) sur lequel sont montées des roulettes (101) de façon à pouvoir être déplacé jusqu'à une position de travail; une plate-forme (20) dans laquelle prend place un opérateur pour effectuer un travail en hauteur; et un moyen (30) de levage placé de manière repliable entre le moyen (10) de déplacement et la plate-forme (20) de façon à élever/abaisser la plate-forme (20), le moyen (30) de levage comprenant une pluralité de moyens (300) de levage de type bloc qui sont empilés d
