Forward and backward driving device for boiler soot blower in power-off maintenance state

The utility model relates to an advance and retreat driving device for a boiler soot blower in a power-off maintenance state, which comprises a sleeve sleeved on a motor tail shaft and used for driving the motor tail shaft to rotate, an end plate arranged at the tail end of a girder of the soot blower, a hole arranged on the end plate and used for the sleeve to enter and exit, and a rotary driving mechanism arranged on the girder and used for driving the sleeve to rotate. A position adjusting mechanism used for driving the sleeve to be away from or close to the motor tail shaft is arranged on the end plate. Through cooperation of the rotary driving mechanism and the position adjusting mechanism, driving force is provided through the small motor, the labor intensity of workers is effectively reduced, and the overhauling efficiency is also remarkably improved. 本实用新型涉及锅炉吹灰器停电检修状态下的进退驱动装置，包括套在电机尾轴上并用于驱动电机尾轴转动的套筒，在吹灰器的大梁的末端设置端板，在端板上设有供套筒进出的洞口，在大梁上设置用于驱动套筒转动的旋转驱动机构，在端板上设置用于驱动套筒远离或接近电机尾轴的位置调节机构。本申请通过旋转驱动机构和位置调节机构的配合
