The invention discloses a lifting appliance for a variable-pitch gear box of an off-center-of-gravity fan, and belongs to the field of fan lifting. A lifting appliance for a variable-pitch gear box of an off-center-of-gravity fan comprises a lifting beam with a hook at the lower end, and further comprises two sets of symmetrically arranged supporting legs which are connected to the lifting beam through elastic lifting mechanisms, vertical plates are fixedly connected to the two sides of the lower end of the lifting beam, and arc-shaped supporting plates are connected to the two vertical plates through telescopic mechanisms; the two sets of spraying pipes are fixedly connected to the upper ends of the two arc-shaped supporting plates correspondingly, and a plurality of blowing nozzles facing the inner walls of the arc-shaped supporting plates are fixedly installed at the lower ends of the two spraying pipes correspondingly; according to the variable-pitch gear box hoisting device, the variable-pitch gear box is not prone to shaking during hoisting, the variable-pitch gear box is prevented from being collided during hoisting, and hoisting can be safer.

    本发明公开了一种用于偏重心风机变桨齿轮箱的吊具,属于风机吊装领域。一种用于偏重心风机变桨齿轮箱的吊具,包括下端设有挂钩的吊梁,还包括:两组对称设置的支撑脚,均通过弹性升降机构连接在所述吊梁上,吊梁的下端两侧均固定连接有立板,两个所述立板上均通过伸缩机构连接有弧形托板;两组喷管,分别固定连接在两个所述弧形托板的上端,两个所述喷管的下端均固定安装有多个朝向弧形托板内壁的吹气嘴;本发明可以使变桨齿轮箱在吊运时不易出现晃动,防止变桨齿轮箱吊运时受到磕碰,即可使吊运更加的安全。
