Traction deviation rectifying equipment facilitating installation of large-section steel truss box girder
The invention discloses traction deviation rectifying equipment facilitating installation of a large-section steel truss box girder. The traction deviation rectifying equipment comprises a controller (2), a support assembly (3), a sliding rail (4), an active deviation rectifying assembly (7), a passive deviation rectifying assembly, a three-dimensional jack assembly (8) and a sliding trolley (10). a bridge pier (1) is located in the support assembly, the sliding rail is arranged on the support assembly, the sliding trolley is arranged at the bottom of a box girder structure and embedded in the sliding rail, the active deviation rectifying assembly is installed between the support assembly and the box girder structure, and the passive deviation rectifying assembly is arranged on the sliding rail. The three-dimensional jack assembly is installed on the pier and abuts against the bottom face of the box girder structure. The three-dimensional jack assembly is combined with the active deviation rectifying assembly and the passive deviation rectifying assembly, accurate adjustment of the vertical position, the transverse position and the longitudinal position can be achieved when the steel truss box girder is pulled and slid, the bolting precision between box girder sections is improved, adverse factors of overwater construction operation are overcome, high-altitude splicing is accurate, the quality and efficiency of steel truss box girder cantilever splicing are improved. The construction safety coefficient is improved.
本发明公开了一种便于安装大节段钢桁架箱梁的牵引纠偏设备，包括控制器(2)、支架组件(3)、滑轨(4)、主动纠偏组件(7)、被动纠偏组件、三维千斤顶组件(8)和滑移小车(10)；桥墩(1)位于支架组件内，滑轨设在支架组件上，滑移小车设在箱梁结构底部并嵌入滑轨内，主动纠偏组件装在支架组件与箱梁结构之间，被动纠偏组件设在滑轨上；三维千斤顶组件装在桥墩上并抵接箱梁结构底面。本发明通过三维千斤顶组件结合主动纠偏组件和被动纠偏组件，能在牵引滑移钢桁架箱梁时实现竖、横、纵向位置的精确调整，提高箱梁节段间栓接精度，克服水上施工作业不利因素，高空拼接精准，提高钢桁架箱梁悬臂拼装的质量与效率，提高施工安全系数。
