The hoisting clamping jaw mechanism comprises a first fixing piece and a clamping jaw device, the clamping jaw device comprises a pull rod and a plurality of clamping pieces, the pull rod is connected to the first fixing piece and movably connected with the first fixing piece, one end of each clamping piece is connected with the first fixing piece, the pull rod comprises a first rod part, and the first rod part is located at one end of the pull rod; in the axial direction of the pull rod and in the direction far away from the first fixing piece, the cross sectional area of part of the first rod part is gradually increased, the multiple clamping pieces jointly clamp the circumferential surface of the pull rod, when the battery pack is hoisted, the first rod part slides upwards, and each clamping piece is opened by the first rod part, so that the clamping pieces move far away from the central axis of the pull rod; according to the lifting clamping jaw mechanism, the clamping pieces are arranged in the lifting holes, so that the clamping pieces abut against the inner walls of the lifting holes, the structure of the lifting clamping jaw mechanism is simplified, the manufacturing cost of the lifting clamping jaw mechanism is reduced, meanwhile, the clamping jaw device fixes a battery pack in the battery pack lifting process, the stability of lifting the battery pack is improved, self-locking can be achieved, and safety is improved.

    本申请公开了一种吊装夹爪机构,包括第一固定件和夹爪装置,夹爪装置包括拉杆和多个夹持件,拉杆连接于第一固定件且与第一固定件活动连接,夹持件的一端与第一固定件连接,拉杆包括第一杆部,第一杆部位于拉杆的一端,在拉杆的轴向且远离第一固定件的方向上,部分第一杆部的横截面积逐渐增大,多个夹持件共同夹持拉杆的周向表面,吊装电池组时,第一杆部向上滑动,各夹持件被第一杆部撑开,使得夹持件远离拉杆的中心轴线移动,使得各夹持件均与吊装孔的内壁抵持,简化了吊装夹爪机构的结构,降低了吊装夹爪机构的制造成本,同时实现了吊装电池组的过程中夹爪装置对电池组的固定,提高了吊装电池组的稳定性,且能够实现自锁,提高了安全性。
