The invention belongs to the technical field of building construction, and particularly relates to a precast beam hoisting and transporting device which comprises a hoisting cross beam, a sling, a first half sliding sleeve, a second half sliding sleeve and a reset spring. Before the precast beam is hoisted, reset springs at the two ends of the interior of an inner cavity push, so that a first half sliding sleeve and a second half sliding sleeve are located in the center of the inner cavity, and the lengths of the two ends of a sling are kept consistent all the time; moreover, in the hoisting process of the precast beam, when the precast beam slightly inclines, a sling drives a first half sliding sleeve and a second half sliding sleeve to slide towards the side along an inner cavity, a reset spring on the side is compressed, and a reset spring on the other side is stretched; elastic force generated by the reset springs on the two sides can promote the first half sliding sleeve and the second half sliding sleeve to return to the center position of the inner cavity, the heights of the two ends of the sling are driven to recover to the horizontal state, and therefore the precast beam is adjusted to recover to the horizontal state, and the stability and safety of precast beam hoisting are improved.
本发明属于建筑施工技术领域,具体的说是一种预制梁起吊运输装置,包括起吊横梁、吊索、一号半滑套、二号半滑套和复位弹簧;预制梁进行吊运之前,内腔内部两端的复位弹簧推动,使得一号半滑套和二号半滑套处于内腔的中心位置,使得吊索两端的长度始终保持一致;并且,在预制梁进行吊运的过程中,当预制梁产生轻微的倾斜时,吊索带动一号半滑套和二号半滑套沿着内腔向该侧滑动,该侧的复位弹簧压缩,并使得另一侧的复位弹簧拉伸;两侧的复位弹簧产生的弹力会促使一号半滑套和二号半滑套复位回到内腔的中心位置,带动吊索两端的高度恢复到水平状态,从而将预制梁调整恢复到水平的状态,继而提高了预制梁吊运的稳定性和安全性。
