The invention discloses a hoisting trolley with a self-blowing dust removal function. The hoisting trolley with the self-blowing dust removal function comprises a crane boom, a sliding rail and a hoisting trolley body; the sliding rail is laid at the lower end of the crane boom; the hoisting trolley body is connected to the lower end of the sliding rail in a sliding mode; a trolley frame is arranged on the outer side of the hoisting trolley body; a hoisting and conveying mechanism is arranged in the center of the interior of the trolley frame; one end of the hoisting and conveying mechanism isprovided with a rotary motor, and a coiling block is arranged at the other end of the hoisting and conveying mechanism; a rotary shaft rod is rotationally connected between the coiling block and therotary motor; a hoisting hook rope is wound on the coiling block; a ring sliding rail is arranged in the trolley frame and around the hoisting and conveying mechanism in an enclosure mode; a fan is connected in the ring sliding rail in a sliding mode; and an exhaust outlet of the fan faces the hoisting and conveying mechanism. In this way, the fan is installed in the hoisting trolley to blow air towards the hoisting and conveying mechanism, and dust and impurities on the hoisting and conveying mechanism are removed in time.
