Traction device of parallel steel strand stay cable and traction method thereof
The invention relates to the field of bridge engineering, and discloses a traction device of a parallel steel strand stay cable and a traction method of the traction device. A center steel wire protruding out of the end face of a steel strand is arranged at one end of the steel strand, and a limiting block is arranged at the end of the center steel wire; the traction device comprises a first connecting sleeve, a second connecting sleeve and a traction winch; the first end of the first connecting sleeve is connected with a steel wire rope on the traction winch, the second connecting sleeve comprises a connector and a sheath, the sheath is provided with a through hole allowing the central steel wire to penetrate through, the side face of the first end of the connector is provided with an open groove allowing the central steel wire to be placed, the connector is provided with a positioning groove used for containing a limiting block, and the positioning groove is communicated with the open groove; the sheath is connected with the first end of the connector, and the second end of the connector is connected with the second end of the first connecting sleeve. According to the invention,a single steel strand can be dragged quickly and easily, a plurality of steel strands can accurately penetrate into correct anchor holes, and the situation of dislocation of the steel strands can be avoided.
本发明涉及桥梁工程领域，公开了一种平行钢绞线斜拉索的牵引装置及其牵引方法，在钢绞线的一端设有凸出其端面的中心钢丝，中心钢丝的端部设有限位块，牵引装置包括第一连接套、第二连接套和牵引卷扬机，第一连接套的第一端与牵引卷扬机上的钢丝绳连接，第二连接套包括连接头和护套，护套设有可供中心钢丝穿过的通孔，连接头的第一端的侧面开设有可供中心钢丝放置的开槽，连接头上设有用于放置限位块的定位槽，定位槽与开槽连通，护套与连接头的第一端连接，连接头的第二端与第一连接套的第二端连接。本发明使单根钢绞线牵引快速、简单，而且保证多根钢绞线准确穿入正确的锚孔，不会出现钢绞线错位的情况。
