The invention relates to the technical field of building construction tools, and discloses a prefabricated floor slab lifting device which comprises a balance plate, a first mounting groove is formed in the bottom of the balance plate, a first motor is fixedly connected to the inner wall of the first mounting groove, and a first bidirectional lead screw is fixedly connected to the driving end of the first motor. The two sides of the outer wall of the first bidirectional lead screw are in threaded connection with moving frames, the outer walls of the two moving frames are fixedly connected with mounting frames, two T-shaped grooves are formed in the bottom of the balance plate, two T-shaped blocks are fixedly connected to the tops of the mounting frames, and the outer wall of each T-shaped block is slidably connected to the inner wall of the corresponding T-shaped groove. By adjusting the distance between the two trapezoidal frames and the two sets of concentric-square-shaped frames, the hoisting device can clamp and fix the prefabricated slabs of different models, the stability in the transportation process is improved, and meanwhile the problems that in the overturning process, the gravity centers of the prefabricated slabs are not stable, the prefabricated slabs shake, and hoisting points cannot be accurately positioned in the falling process are solved.
本申请涉及建筑施工用具技术领域,公开了一种预制楼板起吊装置,包括平衡板,所述平衡板的底部开设有安装槽一,所述安装槽一的内壁固定连接有电机一,所述电机一的驱动端固定连接有双向丝杆一,所述双向丝杆一的外壁两侧均螺纹连接有移动架,两个所述移动架的外壁均固定连接有安装架,所述平衡板的底部均开设有两个T型槽,所述安装架的顶部均固定连接有两个T型块,每个所述T型块的外壁滑动连接在T型槽的内壁。通过对两个梯形架和两组回形架之间距离调整,使得该起吊装置能够对不同型号的预制板进行夹持固定,提高运输过程中的稳固性,同时解决了在翻转过程中预制板重心不稳,出现晃动以及在下落时无法准确定位吊点的问题。
