The invention belongs to the technical field of key and important part dismounting tool design, and relates to a helicopter main blade self-clamping hanger. Comprising an upper clamping plate (9) and a lower clamping plate (8), the top end of the upper clamping plate (9) is provided with an upper clamping plate rocker arm (20); the top end of the lower clamping plate (8) is provided with a lower clamping plate rocker arm (21); the upper clamping plate (9) and the lower clamping plate (8) are connected through a shaft (18) penetrating through the root of the upper clamping plate rocker arm (20) and the root of the lower clamping plate rocker arm (21), and flexible clamping movement between the upper clamping plate and the lower clamping plate is guaranteed. The whole structure adopts a self-clamping mode, manual clamping is not needed, the lower clamping plate (8) moves downwards through the dead weight of the paddle, and then the steel cable (19) pulls the upper clamping plate (9) to conduct clamping. Operation is more convenient, and efficiency is higher.
本发明属于关重部件拆卸工装设计技术领域,涉及一种直升机主桨叶自夹合吊挂。包括上夹板(9),下夹板(8);上夹板(9)顶端带有上夹板摇臂(20),下夹板(8)顶端带有下夹板摇臂(21);上夹板(9)与下夹板(8)间通过贯穿上夹板摇臂(20)根部与下夹板摇臂(21)根部的轴(18)进行连接并保证上下夹板间的灵活夹合运动。本发明的整体结构采用“自夹合”模式,无需人工夹合,通过桨叶自重使得下夹板(8)向下移动,进而钢索(19)牵引上夹板(9)夹合。操作更方便,效率更高。
