Anti-toppling ladder
The invention discloses an anti-toppling ladder. The telegraph pole ladder comprises a ladder body and further comprises clamping structures which are fixed to the top ends of vertical rods on the two sides of the ladder body respectively, and the tail ends of the clamping structures are clamped to the two sides of a telegraph pole when used; the driving structure drives the tail end of the clamping structure to be close to or away from the telegraph pole; during use, the tail end of the supporting structure is attached to the telegraph pole; the attaching position of the tail end of the supporting structure is located below the clamping position of the clamping structure, and an included angle exists between a triangular plane formed by the tail end of the supporting structure and the tail end of the clamping structure and the section of the telegraph pole. According to the scheme, the triangular fixing structure which forms a certain included angle with the section of the telegraph pole is formed by the supporting structure on the front side and the clamping structures on the two sides of the inclined rear side, so that the ladder is more stable, is prevented from inclining, turning over and sliding off, and is adaptive to telegraph poles of different sizes.
本发明公开了一种防倾倒梯子。本发明包括梯子本体，还包括：抱夹结构，分别固定在梯子本体两侧竖杆的顶端，抱夹结构的末端使用时抱夹在电线杆两侧；驱动结构，驱动抱夹结构的末端靠近或远离电线杆；支撑结构，使用时支撑结构的末端与电线杆贴合；支撑结构的末端的贴合位置位于抱夹结构的抱夹位置的下方，支撑结构的末端与抱夹结构的末端构成的三角平面与电线杆的截面存在夹角。本方案通过正面的支撑结构与斜后方两侧的抱夹结构构成与电线杆截面呈一定夹角的三角固定结构，使得梯子更加稳固，防止梯子的倾斜、翻倒与滑落，适配不同尺寸的电线杆。
