Multi-terrain maintenance ladder for power transmission line
The invention relates to a multi-terrain maintenance ladder for a power transmission line. The multi-terrain maintenance ladder comprises a supporting leg assembly, a ladder surface assembly and a connecting rod, the two groups of supporting leg assemblies are respectively hinged to the two sides of the ladder surface assembly; two ends of the connecting rod are respectively hinged between the two groups of supporting leg assemblies; the supporting leg assembly comprises a fixed leg and a telescopic leg; the telescopic legs are connected with the fixed legs in a sliding manner; the fixed legs are steel pipes; a plug is arranged in the steel pipe; a spring is arranged between the plug and the telescopic leg; the telescopic legs are slidably connected with the steel pipes. One end, far away from the spring, of the telescopic leg is conical; set screws for positioning the telescopic legs are arranged on the steel pipes; grooves are formed in the telescopic legs; the set screw abuts against the groove. An auxiliary supporting leg is arranged on the fixed leg; the invention has the following beneficial effects: when the ground is uneven; the telescopic legs extend or retract along the fixed legs under the action of the springs, and after the ladder surface is adjusted to be horizontal, the telescopic legs and the fixed legs are fastened together through set screws.
本发明涉及输电线路用多地形检修梯，包括支腿总成、梯面总成以及连接杆；所述支腿总成数量为两组，分别铰接在梯面总成两侧；所述连接杆两端分别铰接在两组所述支腿总成之间；所述支腿总成包括固定腿以及伸缩腿；所述伸缩腿与所述固定腿滑动连接；所述固定腿为钢管；钢管内设有堵头；堵头与伸缩腿之间设有弹簧；伸缩腿与钢管滑动连接。所述伸缩腿远离弹簧的一端设为锥形；所述钢管上设有用于将所述伸缩腿定位的紧定螺钉；伸缩腿上设有凹槽；紧定螺钉与凹槽抵接；所述固定腿上设有辅助支腿；本发明的有益效果是：当地面不平整时；伸缩腿在弹簧的作用下，沿固定腿伸长或缩短，调整好梯面水平后，用紧定螺钉将伸缩腿与固定腿紧固在一起。
