The invention discloses a positioning device for hoisting steel strands of a box girder, which ensures that the overall position of the steel strands and the relative position of the steel strands do not deviate in the vibrating operation, so that a hoisting shaft can normally penetrate through the steel strands, and the hoisting operation is safely completed. Comprising frame bodies arranged on the two sides of a box girder formwork, each frame body is provided with a first guide groove in the longitudinal direction of the frame body, two cross arms are arranged between the frame bodies, the cross arms are matched with the first guide grooves in the frame bodies to guide the cross arms to move along the first guide grooves, each cross arm is provided with a second guide groove, and the second guide grooves are matched with the first guide grooves. The second guide groove is perpendicular to the first guide groove; two positioning plates are arranged between the two cross arms, and the positioning plates are matched with second guide grooves in the cross arms to guide the positioning plates to move along the second guide grooves; a positioning rod is arranged between the two positioning plates, and a limiting block is arranged on the positioning rod and used for limiting the steel strand.
本发明公开了一种用于箱梁起吊钢绞线的定位装置,在振捣作业中保证钢绞线整体位置以及钢绞线间相对位置不发生偏移,使得吊装轴能够正常穿过钢绞线,安全完成吊装作业。包括设于箱梁模板两侧的架体,各架体上分别沿架体纵向设置有第一导向槽,所述架体之间设有两横担,所述横担配合于架体上的第一导向槽,形成对横担沿第一导向槽移动的导向,各横担上分别设有第二导向槽,所述第二导向槽垂直于第一导向槽;两横担之间设有两定位板,所述定位板配合于横担上的第二导向槽,形成对定位板沿第二导向槽移动的导向;两定位板之间设有定位杆,所述定位杆上设有限位块,用于对钢绞线进行限位。
