Non-welding type steel tube ladder stand foot nail for power transmission steel tube tower
The invention belongs to the technical field of power transmission line engineering iron towers, and particularly relates to a non-welding type steel tube crawling ladder foot pin for a power transmission steel tube tower. The ladder stand foot nail body comprises a cambered surface type structure of a threaded section, a non-screw thread transition section and a cambered surface type upsetting section; the head end of the non-screw-thread transition section is connected with the threaded section, and the tail end of the non-screw-thread transition section is fixedly connected with the head end of the cambered surface type structure of the cambered surface type upsetting section. The fixing device is used for being matched with the threaded section to fix the ladder stand foot nail body. Welding of the root of the foot pin is avoided, and the risk of welding stress concentration of the root of the foot pin is eliminated; the position, bearing shear force, of the foot pin is completely located on the non-screw-thread transition section, the external load bearing capacity of the foot pin is improved, and the fracture risk of the foot pin is reduced. The foot nail is tightly attached to the ladder stand main pipe, so that the possibility that the foot nail body can rotate freely is avoided, and the installation convenience and the use safety of the foot nail are improved.
本发明属于输电线路工程铁塔技术领域，具体涉及一种输电钢管塔用非焊接型钢管爬梯脚钉，包括爬梯脚钉本体和固定装置；所述爬梯脚钉本体包括：螺纹段、无丝扣过渡段以及弧面型镦粗段的弧面型结构；所述无丝扣过渡段的首端与所述螺纹段连接，所述无丝扣过渡段的尾端与所述弧面型镦粗段的弧面型结构的首端固定连接；所述固定装置用于与所述螺纹段配合固定所述爬梯脚钉本体。本发明避免了脚钉根部焊接，消除了脚钉根部出现焊接应力集中的风险；脚钉承受剪切力的位置完全处于无丝扣过渡段上，提升了脚钉承受外载荷的能力，降低了脚钉的断裂风险；脚钉紧密贴合爬梯主管，杜绝了脚钉本体可自由转动的可能，提高了脚钉安装便捷性以及使用安全性。
