The invention relates to the technical field of special hoisting tools, and discloses a special hoisting tool for an arc extinguish chamber of a 500kV ABB circuit breaker. Comprising a main lifting cross beam, a T-shaped handle is slidably connected to the interior of the main lifting cross beam, limiting pressure springs are fixedly connected to the two sides of the T-shaped handle, a steering pulley is arranged on the lower surface of the main lifting cross beam, and connecting crank arms are arranged on the two sides of the steering pulley. Under the action of the gravity of the lifting appliance, the top of the arc extinguish chamber presses the T-shaped handle, the T-shaped handle is jacked to a normally open position, meanwhile, the T-shaped handle drives the movable lifting plate to a locking position, a movable lifting plate hanging plate at the bottom of the movable lifting plate correspondingly acts, the bending action is completed to a position connected with the fixed lifting plate, and after the position is reached, the U-shaped bayonet lock is inserted and fixed; when the device is used, the hoisting risk can be reduced, the arc extinguish chamber is prevented from falling off and rolling during hoisting, the working efficiency is improved, and rapid hoisting is realized.

    本发明涉及吊装专用工具技术领域,且公开了500kVABB断路器灭弧室吊装专用工具。包括主吊横梁,所述主吊横梁的内部滑动连接有T型把手,所述T型把手的两侧均固定连接有限位压簧,所述主吊横梁的下表面设置有转向滑轮,所述转向滑轮的两侧均设置有连接拐臂,本发明在未使用时,T型把手为常闭状态,插入主吊横梁内,在吊具自身重力作用下,灭弧室顶部压动T型把手,将T型把手顶至常开位置,同时T型把手带动活动起吊板至闭锁位置,活动起吊板底部的活动起吊板挂板相应动作,完成弯曲动作到和固定起吊板连接位置,到达位置后将U型卡销插入固定,当该装置在使用时,可降低吊装风险,防止灭弧室吊装时脱落、滚动,提高工作效率,实现快速吊装。
