The invention discloses a precast slab bearing part hoisting device. The precast slab bearing part hoisting device comprises a horizontal rod and telescopic sleeves connected to the two ends of the horizontal rod. The telescopic sleeve is in sliding connection with the horizontal rod; clamping pieces are symmetrically arranged below the telescopic sleeve, each clamping piece comprises a fixing plate and a clamping plate, the fixing plates and the clamping plates are hinged through two connecting plates, the connecting plates are arranged between the fixing plates and the clamping plates in left-right symmetry, the tops of the connecting plates are connected with the surfaces of the fixing plates through hinge shafts, baffles are arranged at the two ends of each hinge shaft correspondingly,torsional springs are arranged on the inner sides of the baffles, and the two ends of the torsional springs are connected with the side faces of the fixing plates and the connecting plates correspondingly. The problem that after a precast slab is hoisted, the precast slab is likely to incline due to the fact that the gravity center is uncertain in the hoisting process is solved.
本发明公开了一种预制板承重部吊装装置,包括有水平杆和连接在水平杆两端的伸缩套;所述伸缩套与水平杆滑动连接;所述伸缩套下方对称设置有夹持件,所述夹持件包括固定板和夹持板,所述固定板和夹持板通过两个连接板铰接,所述连接板左右对称设于固定板和夹持板之间,所述连接板顶部与固定板表面通过铰接轴连接,所述铰接轴两端分别设有挡板,所述挡板内侧设有扭簧,所述扭簧两端分别与固定板和连接板侧面连接。解决了预制板在吊起后,在吊装过程中,由于重心不确定,可能会造成预制板歪斜的问题。
