The chain lifting device structure comprises a chain lifting device body (1), a knife switch (2), a balancing weight (6), a hydraulic oil cylinder (7) and a rolling wheel (9), the knife switch (2) is arranged at the top of the chain lifting device body (1) in the mode that one side of the knife switch (2) can be opened and closed, and an upper support of the hydraulic oil cylinder (7) is fixed to the position, close to a rotating shaft, of the knife switch (2). A lower support of the hydraulic oil cylinder (7) is fixed to one side of the chain lifting device body, the rotating end of the knife switch is arranged on one side of the top of the chain lifting device body through an opening and closing rotating shaft (11), the free end of the knife switch is fixed to the other side of the top of the chain lifting device body in an opening and closing mode, the middle of the knife switch (2) is pressed on the top of a rolling wheel (9), and a balancing weight (6) is arranged on the knife switch (2). Limiting devices are arranged on the two sides of the knife switch (2). According to the chain lifting device, opening and closing of the knife switch are achieved in two modes, the safety is improved by arranging a protection device, and personnel and equipment are effectively prevented from being damaged.
