The invention belongs to the technical field of electrical equipment maintenance and discloses a casing dismounting tool, dismounting method and mounting method.The casing dismounting tool comprises a lifting hook, a first rope, a fixed pulley and a second rope, the lifting hook is suitable for being connected to a lifting device, the first end of the first rope is connected to the lifting hook, and the second end of the first rope is suitable for being connected to a casing; the multiple first ropes are distributed in the circumferential direction of the sleeve at intervals, the fixed pulley is connected to the lifting hook, one part of the second rope is wound around the fixed pulley, the first end of the second rope is suitable for being connected to a lead, the second end of the second rope is suitable for being connected to a winch, and/or the second end of the second rope is suitable for being pulled by manpower. The sleeve is dragged through the lifting hook and the first rope, and the lead is dragged through the fixed pulley and the second rope penetrating through the fixed pulley, so that a worker can conveniently perform traction control on the lead when disassembling and assembling the sleeve, and accidents such as friction between the lead and the inner wall of the sleeve and lead falling are greatly reduced.

    本发明属于电力设备维护技术领域并公开了一种套管拆装工具、拆除方法及安装方法,所述套管拆装工具包括吊钩、第一绳索、定滑轮和第二绳索,吊钩适于连接于起吊装置,第一绳索的第一端连接于吊钩,第一绳索的第二端适于连接于套管,第一绳索有多个,多个第一绳索沿套管的周向间隔分布,定滑轮连接于吊钩,第二绳索的一部分缠绕于定滑轮,第二绳索的第一端适于连接于引线,第二绳索的第二端适于连接于卷扬机,和/或,第二绳索的第二端适于由人力牵引。本发明通过吊钩和第一绳索对套管进行牵引并通过定滑轮和穿过定滑轮的第二绳索对引线进行牵引,便于工作人员对套管进行拆装时对引线进行牵引控制,大幅减少引线与套管内壁摩擦和引线掉落等事故。
