【Abstract】 According to the present state that excessive shaft crevice water in the coal mine shaft and large scale in the shaft wall lead to seize and drop the cage, which always threaten the safety lift of the coal mine, a new type scale cutting machine is developed. The designed door frame operating mechanism can clearly cut scale in the circular section of shaft wall under the abominable condition in the shaft, such as narrow space, wet, excessive shaft crevice water and so on, and can work safely and reliably, and has good cutting scale effect.更多还原
