Quick hanging and fixing mechanism for tail end operation tool of multifunctional crown block for aluminum electrolysis

A quick hanging and fixing mechanism for a tail end operation tool of an aluminum electrolysis multifunctional crown block can quickly fix and clamp the tail end operation tool and a fixing frame, can perform self-adaptive positioning, and can reliably fix the replaced tail end operation tool. Each T-shaped frame comprises a left cross arm, a right cross arm and a vertical arm, the left cross arm is provided with a conical head, the fixing frame is provided with a conical sleeve matched with the conical head, a clamping oil cylinder is horizontally installed on the side face of the conical sleeve, and the lower end of the vertical arm is connected with a tail end operation tool. The public lifting mechanism drives the T-shaped frame to ascend to the corresponding fixing position of the fixing frame and then move horizontally to drive the T-shaped frame to get close to the fixing frame, and after the conical head of the T-shaped frame is aligned with the conical sleeve of the fixing frame, the public lifting m
