Middle/front supporting leg structure of bridge erecting machine suitable for erecting small-radius curved beam
The invention relates to a middle/front supporting leg structure of a bridge erecting machine suitable for erecting a small-radius curved beam. The middle/front supporting leg structure of the bridgeerecting machine comprises an upper stand column, a transverse moving wheel box and a horizontal connecting rod, wherein the upper stand column is connected with a guide beam, a horizontal rotating device is arranged between the upper stand column and the transverse moving wheel box, and when the small-radius curved beam is erected, horizontal rotation between the upper stand column and the guidebeam and the transverse moving wheel box is achieved through the horizontal rotating device. Compared with the prior art, the middle/front supporting leg structure has the advantages that the middle/front supporting leg transverse moving wheel box is connected with the middle/front supporting leg upper stand column and the guide beam through the horizontal rotating device, and a horizontal telescopic device is additionally arranged in the middle/front supporting leg connecting rod to connect supporting legs on the two sides, so that large-angle turning of the bridge erecting machine is achieved, and the guide beam does not generate bending moment during turning; and the middle/front supporting leg structure can adapt to the erection scenes of most curved section beam pieces, and adaptivelyperform large-angle turning instantaneously with high turning efficiency.
本发明涉及一种适用于架设小半径曲线梁的架桥机中/前支腿结构，所述架桥机中/前支腿结构包括上部立柱、横移轮箱和水平连杆，所述上部立柱与导梁连接，所述上部立柱与横移轮箱之间设有水平旋转装置，架设小半径曲线梁时通过水平旋转装置实现上部立柱与导梁、横移轮箱之间的水平旋转。与现有技术相比，本发明通过水平旋转装置连接中/前支腿横移轮箱与中/前支腿上部立柱及导梁，在中/前支腿连杆中加上水平伸缩装置连接两边支腿，从而实现架桥机的大角度转向，并在转向时导梁不产生弯矩；能够匹配大多数曲线段梁片的架设场景，能够瞬间自适应地产生较大角度的转向，转弯效率高。
