The invention belongs to the technical field of traction, and particularly relates to a large-load-resistant traction mechanism. The large-load-resistant traction mechanism comprises a hole drill and a puller. When the traction mechanism designed by the invention is used, firstly, a round hole with a specified inner diameter and depth needs to be drilled in a wall through a common twist drill, then, an annular groove is formed in the inner wall of the original round hole in a broaching mode through the designed hole drill, after the annular groove is formed through broaching, the puller is plugged into the round hole, a second sliding push sleeve in the puller is driven to push a second sliding ring to slide, then traction supporting blocks distributed in the circumferential direction of the puller can move into the annular groove, the traction supporting blocks are matched with the annular groove to reinforce the traction force which can be met by the puller, and the traction mechanism is suitable for single-side large-load traction of the wall.
本发明属于牵拉技术领域,尤其涉及一种耐大负荷的牵拉机构,它包括孔钻、拉头;在使用本发明设计的牵拉机构时,首先需要通过普通的螺旋钻在墙上钻出一个内径大小和深度指定的圆孔;之后在使用本发明设计的孔钻在原先圆形孔的内壁上扩出一个环形槽,在括出环形槽后,将拉头塞入圆孔内,且通过驱动拉头中的第二滑动推套使得第二滑动推套推动第二滑环滑动,使得拉头周向分布的牵拉支撑块移动到环形槽内,通过牵拉支撑块与环形槽的配合加强拉头能够满足的牵引力,适用于墙体单侧大负荷的牵拉。
