The maintenance and replacement device comprises a sliding plate and a steel wire rope connected with a mounting box, the mounting box comprises an upper top plate and a lower bottom plate which are connected through a fixed connecting rod, and the fixed connecting rod is sleeved with a sliding barrel with a fixed stop lever; the sliding cylinder is connected with a magnetic plate which is in magnetic fit with the electromagnet, a touch pressing plate which is in touch pressing fit with the electromagnet signal switch is arranged in the hub, a sliding clamping block which is matched with and presses the air blower signal switch extends out of the sliding cylinder, and the fixed stop lever is connected with an elastic air bag which is supplied with air by the air blower. The variable-pitch system parts are conveyed into the hub through the elevator and the sliding plate so that potential safety hazards can be reduced, the variable-pitch system parts are blocked by the fixed blocking rods when the variable-pitch system parts are conveyed, and the elastic air bags expand to provide damping buffering; and when the variable pitch system parts are replaced, the fixed stop lever and the elastic air bag are separated from the variable pitch system parts, so that the disassembly and replacement efficiency is improved.

    本发明公开了一种变桨系统零部件的维护更换装置及风力发电机组,包括滑动板和连接安装箱的钢丝绳,所述安装箱包括通过固定连杆连接的上顶板、下底板,且固定连杆上套设有带固定挡杆的滑筒,且滑筒连接有与电磁铁磁性配合的磁性板,且轮毂内设置有与电磁铁信号开关触压配合的触压板,所述滑筒内伸出有配合压迫鼓风机信号开关的滑动卡块,所述固定挡杆连接有由鼓风机供风的弹性气囊,本发明通过提升机和滑动板将变桨系统零部件输送至轮毂内部来降低安全隐患,并在运输变桨系统零部件时使得固定挡杆挡住变桨系统零部件,弹性气囊膨胀提供减震缓冲,还在更换变桨系统零部件时使得固定挡杆、弹性气囊离开变桨系统零部件,提高拆卸更换效率。
