The invention discloses a pipe piece dismantling lifting appliance which comprises a first arc-shaped plate, a second arc-shaped plate and a connecting structure connected with the first arc-shaped plate and the second arc-shaped plate, and the connecting structure comprises a first connecting plate, a second connecting plate and a third connecting plate connected with the first connecting plate and the second connecting plate. The first connecting plate, the second connecting plate and the third connecting plate form a box body structure, a hoisting part is arranged on the first arc-shaped plate, a mounting hole is formed in the connecting structure, and the mounting hole corresponds to a duct piece connecting hole formed in a duct piece to be dismantled. Bolts are arranged in the mounting holes in a penetrating mode, and the bolts are used for being inserted into the duct piece connecting holes to connect and fix the duct piece dismantling lifting appliance and the duct piece to be dismantled. According to the duct piece dismantling lifting appliance, the contact area between the lifting appliance and the duct piece can be increased, stress is uniform, the phenomenon that the duct piece is damaged by collision is effectively avoided, the integrity and the repeated utilization rate of the dismantled duct piece are improved, and the safety guarantee of dismantling construction is improved.
