The invention relates to the field of petroleum machinery, in particular to a lifting mechanism for a drill floor manipulator. The drill floor manipulator comprises a manipulator mounting seat; a frame body which is in vertical sliding fit with the manipulator mounting seat; fixed pulley blocks arranged at the upper part of the frame body; movable pulley blocks; telescopic devices, wherein one ends of the telescopic devices are connected with the lower portion of the frame body, the other ends of the telescopic devices are connected with the movable pulley blocks, the telescopic devices can drive the movable pulley blocks to move and are located on the sides, away from the fixed pulley blocks, of the movable pulley blocks; and steel wire ropes, wherein one ends of the steel wire ropes are connected with the manipulator mounting seat, and the other ends of the steel wire ropes sequentially pass the fixed pulley blocks and the movable pulley blocks and then are connected with the frame body. According to the lifting mechanism for the drill floor manipulator, ascending and descending of the manipulator mounting seat can be effectively achieved, and therefore the purpose of avoiding a catway operation area is achieved.
