Bridge erecting machine suitable for limited space
The invention discloses a bridge girder erection machine suitable for a limited space. The bridge girder erection machine comprises a front supporting leg, a rear supporting leg, a crown block frame and a hoisting winch. One end of the crown frame is connected to the front supporting leg and the other end is connected to the rear supporting leg; the upper side of the crown block frame is provided with a moving frame used for moving along the crown block frame. The movable frame is provided with a suspended movable pulley block; a directional guide wheel is arranged above the hoisting winch; the hoisting winch is fixed to the concrete box girder body, and a hoisting steel wire rope of the hoisting winch is connected to the suspension movable pulley block through guiding of the directional guide wheel. The bridge girder erection machine suitable for the limited space can meet the limitation of the limited space, so that in any limited space, the bridge girder erection machine can be adopted for installing concrete precast beams, and factory-like and large-scale prefabrication can be carried out on beam bodies erected through the bridge girder erection machine.
本发明公开了一种适用于受限空间的架桥机，包括：前支腿、后支腿、天车架和起重卷扬机；天车架的一端连接至前支腿且另一端连接至后支腿；天车架上侧设有用于沿天车架进行移动的移动架；移动架设有悬吊动滑轮组；起重卷扬机上方设有定向导向轮；起重卷扬机固定于砼箱梁梁体上且其起重钢丝绳通过定向导向轮的导向连接至悬吊动滑轮组。本发明的适用于受限空间的架桥机能够满足受限空间的限制，使得在任何受限空间下，安装砼预制梁均可采用该架桥机，通过使用该架桥机进行架装的梁体均可实行工厂化、规模化预制。
