Extra-small radius universal bridge girder erection machine

HUANG WEIHONG

The invention discloses an extra-small radius universal bridge girder erection machine. The extra-small radius universal bridge girder erection machine comprises a frame and a box body; a square groove is formed in the inner top wall of the frame; a fixing block is fixedly connected to the lower portion of the outer side face of the frame; a rotating structure is arranged below the fixing block; abearing structure is arranged on one side face of the square groove; a sliding rail is fixedly connected to the upper surface of the frame; and a crown block structure is arranged on the outer side surface of the slide rail. According to the extra-small radius universal bridge girder erection machine, through the arrangement of the rotating structure, the extra-small radius universal bridge girder erection machine has the effect of adjusting the height of the frame, so that the effect of automatically adjusting the height of the bearing structure is achieved, and meanwhile, the effect of facilitating hoisting is also achieved. Through the cooperative arrangement of an upper-stage roller, an upper-stage connecting rod, a servo motor, a lower-stage connecting rod, a lower-stage roller and arotating disc, the angle can be adjusted at will according to the field construction curvature in the using process, then the effect of low risk is achieved, and the purpose of high stability is achieved.

本发明公开了一种特小半径通用架桥机，包括框架和箱体，框架的内顶壁开设有方槽，框架的外侧面下部固定连接有固定块，固定块的下方设置有转动结构，方槽的一侧面设置有承载结构，框架的上表面固定连接有滑轨，滑轨的外侧面设置有天车结构。该特小半径通用架桥机，通过转动结构的设置，使该特小半径通用架桥机具备了可以调节框架高度的效果，从而起到了自主调节承载结构高度的作用，同时也起到了便于起吊的作用，通过上级滚轮、上级连杆、伺服电机、下级连杆、下级滚轮和转盘的配合设置，在使用的过程中可以根据现场施工曲度任意调动角度，进而起到了风险低的作用，达到了稳定性强的目的。
