The hoisting clamp comprises two sets of four-connecting-rod clamps A and B which are connected side by side in a mirroring mode through a plurality of pin shafts, and two sets of ratchet wheel self-locking mechanisms C and D are installed between the two sets of four-connecting-rod clamps and are responsible for self-locking when clamping rods of the two sets of four-connecting-rod clamps are opened and clamped; a rotating shaft is movably arranged between the two sets of four-connecting-rod clamp clamping rods; the ratchet wheel self-locking mechanism comprises a ratchet wheel, a stop pawl and a spring pressing sheet; the ratchet wheel is mounted on a pin shaft in the middle of a second clamping rod A and a second clamping rod B of the two sets of four-connecting-rod clamps; the stop pawl is fixedly mounted on a rotating shaft and is matched with the ratchet wheel to realize locking action; the spring pressing sheet is fixedly mounted on the inner side of a first clamping rod and is used for pressing the stop pawl on ratchets of the ratchet wheel; the tooth directions of the two ratchet wheels of the two ratchet wheel self-locking mechanisms are opposite. The shaft part hoisting device is simple in structure, convenient to operate, high in hoisting efficiency and high in safety, hoisting and mounting work of shaft parts is facilitated, and the mounting efficiency and the operation safety are improved.

    本发明涉及一种带双向自锁的吊装夹具,包含通过多个销轴并排镜像连接的两套四连杆夹具A和B,在两套四连杆夹具之间安装有两套棘轮自锁机构C和D,分别负责两套四连杆夹具夹持杆之间张开和夹紧时的自锁;在两套四连杆夹具夹持杆之间活动设置有转轴;所述棘轮自锁机构包含安装在位于两套四连杆夹具的第二夹持杆A和第二夹持杆B中部销轴上的棘轮、固装在转轴上与棘轮配合实现锁止动作的止动棘爪、固装在第一夹持杆内侧用于将止动棘爪压紧在棘轮棘齿上的弹簧压片;两个棘轮自锁机构的两个棘轮的齿向相反。本发明结构简单、操作方便、吊装效率高、安全性高,方便轴类零件的吊装和安装工作,提高安装效率和作业安全性。
