The invention discloses a special hoisting tackle for an overhead conductor, and relates to the technical field of hoisting tools. The hoisting tool comprises a fixed part and a pulley part, the fixed part is a hollow sleeve 9, the sleeve 9 comprises an outer-layer metal sleeve 2 and an inner-layer rubber sleeve 3, the sleeve 9 is an annular pipe formed by rotationally connecting two semicircular cambered surfaces through a hinge shaft 1, and a connecting bolt 4 is outwards arranged at the edge of the lower portion of the outer-layer metal sleeve 2 on one cambered surface. The connecting bolt 4 is downwards connected with two pulley protection plates 8 through a steering shaft 5, and bearing pulleys 6 are arranged in the two pulley protection plates 8. The problems that in the prior art, the contact area of a tackle, a conductor and a ground wire is small, an aluminum wire on the outer layer of the hoisted conductor is crushed, and the conductor is possibly broken are solved.

    本发明公开了一种用于架空导线上的专用起吊滑车,涉及起吊工具的技术领域。所述起吊工具包括固定部分和滑轮部分,所述固定部分为空心套管9,所述套管9包括外层金属套管2和内层橡胶套管3,所述套管9为两半圆形弧面通过合页轴1旋转连接成的圆环形管,一侧弧面的外层金属套管2下方边缘处向外设置连接螺栓4,所述连接螺栓4向下通过转向轴5连接有两个滑轮护板8,两个滑轮护板8内设置轴承滑轮6。解决了现有技术中滑车与导、地线接触面积小,起吊后导线外层铝线会被压伤,可能会使导线断股的问题。
