Bridge prestress whole steel strand pulling equipment
The invention discloses bridge prestress whole steel strand pulling equipment, and relates to steel strand pulling equipment. The equipment comprises a machine head, the machine head is provided witha plurality of roller mechanisms, a first telescopic mechanism, a first guide wheel mechanism and a second guide wheel mechanism, the first telescopic mechanism, the first guide wheel mechanism and the second guide wheel mechanism are located above the roller mechanisms, the machine head is slidably connected with a rack and can move on the rack in the direction of a steel strand, the rack is slidably connected with a vehicle body, a lifting mechanism is arranged above the vehicle body and drives the machine head connected with the rack to ascend and descend vertically, rope tighteners are arranged above the vehicle body, and rollers and liftable supporting columns are arranged at the four corners below the vehicle body. The equipment has the functions of automatic lifting, automatic longitudinal moving, automatic clamping and automatic whole bundle pulling, continuous whole bundle pulling of steel strands is achieved, the situation of uneven stress of the steel strands during tensioning is improved in steel strand pulling construction, labor and time for whole bundle pulling operation are saved, wear-resisting rubber is arranged on the surfaces of all the rollers, friction force during steel strand clamping is increased, and the phenomenon that the steel strands are scratched during clamping and pulling is avoided.
本发明公开了一种桥梁预应力整束钢绞线穿束设备，涉及钢绞线穿束设备。包括机头，机头设有若干滚轮机构和位于其上方的第一伸缩机构、第一导轮机构和第二导轮机构，机头滑动连接台架并在台架上可沿钢绞线方向移动，台架滑动连接车体，车体上方设有升降机构，带动与台架连接的机头上下升降，车体上方设有紧绳器，车体下方四角设有滚轮和可升降的支柱。本发明有自动升降、自动纵向移动、自动夹紧、自动整束穿束功能，实现钢绞线整束连续穿束，钢绞线穿束施工中改善了张拉时钢绞线受力不均的状况，节省了整束穿束作业人工及时间，各滚轮表面设置耐磨橡胶，增加了夹紧钢绞线时的摩擦力，并且避免了夹紧穿束时对钢绞线的划伤现象。
