Abstract:

Disclosed is a height adjustment device for a rotunda of a boarding bridge. A height adjustment device for a rotunda of a boarding bridge can comprise: an outer column which fixes a rotunda and ascends and descends; an inner column which is connected to the outer column and is fixed on the ground surface; a vertical screw which is placed on the lower end of the rotunda; a nut which is formed in the inner central part of the outer column or the inner column so as to interlock in correspondence to the outside diameter of the vertical screw; and rails which are provided on one side of the outer column or the inner column and are formed in correspondence to each other so as to assist the ascent and descent of the outer column, wherein the lateral weight can be distributed by means of the rails and the nut. By maintaining a gap in which an inner column and an outer column can be assembled and reducing the occurrence of the bending of a vertical screw, the lateral weight of a height adjustment device for a rotunda of a boarding bridge can be distributed.
