The invention discloses a hoisting assistive device which comprises a hoisting arm and two clamping mechanisms. The two clamping mechanisms are arranged on the two sides of the hoisting arm correspondingly and define a clamping space used for containing materials. The two clamping mechanisms are hinged to the hoisting arm through a rotating shaft and can move towards or away from the hoisting armso that the two clamping mechanisms can be matched to clamp or loosen the materials placed in the clamping space. The hoisting assistive device has the advantages of being simple in structure, convenient to maintain and low in use cost, the materials can be hoisted after being placed in the clamping space, the hoisting efficiency is high, and operation is convenient and fast. Besides, the number of contact points between the hoisting assistive device and the materials is large, the materials can be prevented from inclining in the hoisting process, the materials are protected against damage, the hoisting stability is improved, and the hoisting safety is guaranteed.
本发明公开了一种吊运辅具,所述吊运辅具包括起吊臂和两个夹持机构,两个所述夹持机构分设于所述起吊臂的两侧并围成用于放置物料的夹持空间;两个所述夹持机构通过一转轴与所述起吊臂铰接,且两个所述夹持机构能相对所述起吊臂相向或相背运动,以对应使两个所述夹持机构配合将放置于所述夹持空间内的所述物料夹紧或放松。本发明的吊运辅具具有结构简单、便于维护以及使用成本低的优点,且只需将物料放入夹持空间内即可起吊,吊运效率高,操作方便快捷。另外,吊运辅具与物料的接触点多,可避免物料在吊运过程中发生倾斜,保护物料不受损伤,提高了吊运的稳定性,保证了吊运的安全性。
