Folding ladder for rush-repair of power grid
The invention discloses an electric power grid first-aid repair folding ladder, which comprises a folding ladder main body and nailing ladder feet, each nailing ladder foot comprises a supporting seat, a primary nailing mechanism and a secondary nailing mechanism, the supporting seat is hinged to the bottom of the folding ladder main body, the primary nailing mechanism is installed on the supporting seat and is provided with a positioning pin which can be inserted into the ground when being pressed down, and the secondary nailing mechanism is installed on the supporting seat. The re-nailing mechanism is installed on the supporting base and provided with a mandrel with a spiral blade, and the mandrel can synchronously drive the spiral blade to be screwed into the ground when being rotated. A positioning needle can be inserted into the ground through the primary nailing mechanism so that primary fixing of the folding ladder body can be rapidly achieved, follow-up operation can be facilitated, and then a spiral blade is screwed into the ground when a mandrel of the secondary nailing mechanism is rotated so that secondary fixing of the folding ladder body can be completed; therefore, the emergency repair ladder can be normally used in mountain land and other uneven ground environments, and the operation safety of maintainers is ensured.
本发明公开了电力电网抢修折叠梯，包括折叠梯主体和钉地梯脚，所述钉地梯脚包括支撑座、初钉机构和复钉机构，所述支撑座铰接于折叠梯主体的底部，所述初钉机构安装在支撑座之上且设有可在被下压时插入地面内的定位针，所述复钉机构安装在支撑座之上且设有带有螺旋叶片的芯轴，所述芯轴可在被旋转时同步带动螺旋叶片拧入地面内。本发明可利用初钉机构将定位针插入地面内以快速实现折叠梯主体的初步固定并方便后续操作，再在旋转复钉机构的芯轴时将螺旋叶片拧入地面内以完成折叠梯主体的二重固定，从而保证抢修梯在山地等无平整地面环境中的正常使用，保证检修人员的操作安全性。
