The invention relates to the technical field of crane equipment installation, and particularly discloses a method for simultaneously and quickly replacing a movable pulley block and a steel wire rope of a crane, which comprises the following steps of: dropping an old movable pulley block to an operation area, placing a new movable pulley block in the operation area, and welding nuts on an old steel wire rope head and a new steel wire rope head respectively; a rope head of a new steel wire rope manually penetrates through a first penetrating point, a second penetrating point, a third penetrating point and a fourth penetrating point of a new movable pulley block on a new movable pulley block, an old steel wire rope pulls the new steel wire rope to penetrate through a first fixed pulley block, a second fixed pulley block and a third fixed pulley block of a fixed pulley block, and the new steel wire rope and the old steel wire rope are connected through an iron wire penetrating through a nut. The new steel wire rope and the old steel wire rope are disconnected and the iron wire is disassembled, four times of connection and four times of disconnection are needed in the process, and the method is short in time, saves labor, reduces workload, improves operation efficiency and greatly reduces operation intensity.

    本发明涉及起重机设备安装技术领域,具体公开了一种起重机动滑轮组和钢丝绳同时快速更换的方法,将旧动滑轮组下落至作业区,并放置新动滑轮组于作业区,旧钢丝绳绳头和新钢丝绳绳头分别焊接螺帽,新钢丝绳的绳头手动穿过新动滑轮组上新动滑轮片的第一穿入点、第二穿入点、第三穿入点和第四穿入点,旧钢丝绳牵引新钢丝绳穿过定滑轮组的第一定滑轮片、第二定滑轮片和第三定滑轮片,新旧钢丝绳连接用铁丝穿过螺帽连接,新钢丝绳和旧钢丝绳断开拆开铁丝即可,中间需要4次连接,4次断开,此方法所需时间短,节省了力气,减少了工作量,提高了作业效率,大大降低了作业强度。
