The invention discloses a counter weight limiting device with a self-cleaning function, which comprises a counter weight sleeved on the outer side of a steel wire rope and connected with a traction rope, and further comprises an inner sleeve arranged on the inner ring of the counter weight and sleeved on the outer side of the steel wire rope; the inner sleeve is of a sectional structure; a plurality of sets of oil stain cleaning mechanisms are arranged on the side wall of the inner sleeve; and a pressure sensing unit is arranged in the inner sleeve. The invention further discloses a warning control method based on the heavy hammer limiting device with the self-cleaning function. The problem that an existing heavy hammer limiting device is in contact with lubricating oil on the outer surface of a steel wire rope to cause internal oil stain accumulation is solved, and the situation that the existing heavy hammer limiting device is mistakenly triggered is prevented.
