The invention discloses a dismounting and hoisting method for a grinding roller device of a coal mill, which is characterized in that a lifting hook is arranged above the outer side of an access door corresponding to the grinding roller device, a lifting rope is hung on the lifting hook, and the other end of the lifting rope penetrates through the access door and is fixedly connected to a grinding roller seat of the grinding roller device; the lifting hook ascends, and a rope body of the lifting rope abuts against and is supported on the edge of the top in a door frame of the access door and pulls the grinding roller device outwards; a pulling device is installed on the ground outside the access door, a pull rope is arranged between the pulling device and a supporting arm of the grinding roller device, one end of the pull rope is fixedly connected to the pulling device, and the other end of the pull rope is fixedly connected to the end, extending out of the access door, of the supporting arm of the grinding roller device. Then the lifting hook and the pulling device simultaneously apply acting force to turn over the grinding roller device out of the access door; and the rotating inserting shaft between the grinding roller device and the grinding roller machine shell is detached, then connection between the lifting rope and the grinding roller device and connection between the pull rope and the grinding roller device are detached, the lifting appliance is installed on the grinding roller device again, and the grinding roller device is lifted through the lifting hook.

    本发明公开了一种磨煤机磨辊装置的拆卸吊装方法,在磨辊装置对应的检修门的外侧上方设置吊钩,在吊钩上挂接有吊绳,吊绳的另一端穿过于检修门且固定连接在磨辊装置的磨辊座上;吊钩上升,吊绳的绳体抵接支撑在检修门的门框内顶部边缘处并对磨辊装置向外拉动;在检修门外的地面上安装拉扯装置,拉扯装置与磨辊装置的支撑臂之间设置有拉绳,拉绳的一端固定连接在拉扯装置上,另一端固定连接在磨辊装置的支撑臂伸出检修门一端的端部上,然后吊钩和拉扯装置同时施加作用力使磨辊装置翻转出检修门外;拆除磨辊装置与磨辊机壳体之间的转动插轴,再分别拆除吊绳和拉绳与磨辊装置之间的连接,重新在磨辊装置上安装吊具并利用吊钩起吊磨辊装置。
