Steel beam pushing and dragging steel strand erecting system

The utility model discloses a steel strand erecting system for pushing and dragging a steel beam. The steel strand erecting system aims at effectively avoiding scraping damage to a pier column in the erecting process of dragging the steel strand. Therefore, the steel strand erecting system comprises an erecting antenna which is obliquely erected above a bridge in the longitudinal direction of the bridge and is high in front and low in rear, a hanging pulley which is installed on the erecting antenna in a sliding mode, and a driving mechanism which drives the hanging pulley to move back and forth along the erecting antenna. Wherein the two ends of the erected antenna are fixed to a pushing jack fixing pier at the front end of a bridge and a steel beam splicing platform at the rear end of the bridge respectively, and a dragging steel strand of the steel beam pushing and dragging system is fixedly connected to the hanging pulley. 本实用新型公开了一种钢梁顶推拖拉钢绞线架设系统，旨在有效避免拖拉钢绞线架设过程中与墩柱产生刮擦损伤。为此，本实用新型提供的钢梁顶推拖拉钢绞线架设系统，包括沿桥梁纵向前
