The invention relates to the technical field of bridge girder erection machines, and discloses a middle supporting leg and a bridge girder erection machine. The main body comprises an upper cross beam, a lower cross beam and an adjustable vertical beam, a partial load beam is arranged on the upper cross beam, and the curved beam is rotationally connected to the partial load beam and used for hanging the main beam; the adjustable vertical beam comprises a guide sleeve, a guide column, a movable cross beam and an adjusting oil cylinder, rotation and deviation of the main beam relative to the upper cross beam are achieved through the partial load beam and the rotatable curved beam, and the moving distance of the lower cross beam can be increased through the guide column, the guide sleeve, the movable cross beam and the adjusting oil cylinder. The technical problems that in the prior art, a second column cannot rotate and horizontally move relative to a main beam at the same time, contraction of a side arm of the second column is limited, and the application scene is limited are solved, and the technical effects that the second column can rotate and horizontally move relative to the main beam at the same time, and the contraction length is larger are achieved.

    本发明涉及架桥机的技术领域,公开了一种中支腿及架桥机,包括主体和曲梁;主体包括上横梁、下横梁和可调竖梁,上横梁上设置有分载梁,曲梁转动连接于分载梁,曲梁用于吊设主梁;可调竖梁包括导套、导柱、活动横梁和调节油缸,通过分载梁和可旋转的曲梁,实现了主梁相对上横梁的旋转和偏移,而通过导柱、导套、活动横梁和调节油缸,能够提高了下横梁的移动距离,解决了现有技术中的二号柱无法同时实现相对主梁旋转和平移,以及二号柱侧臂收缩受限,适用场景有限的技术问题,达到了二号柱可以同时相对主梁旋转和平移,以及收缩长度更大的技术效果。
