Anti-toppling combined ladder for power grid infrastructure construction and use method of anti-toppling combined ladder
The invention provides an anti-toppling combined ladder for power grid infrastructure construction and a using method, and belongs to the technical field of power grid infrastructure construction. The device comprises four limiting mechanisms and an expansion and contraction mechanism. When the four ladder stand columns are placed in the four grooves in a one-to-one correspondence mode, an operator presses the ladder stand columns downwards, after the ladder stand columns apply downward pressure to the expansion and contraction mechanism, the size of the expansion and contraction mechanism is increased, the ends, away from the ladder stand columns, of the limiting mechanisms are driven to move in the direction away from the central axes of the ladder stand columns, and the limiting mechanisms are attached to the grooves; therefore, the main ladder and the auxiliary ladder do not move when an operator works, and the technical problems that in the prior art, the stability of contact between a ladder stand column and the ground is poor, and the ladder is prone to toppling over when the ladder is closed are solved.
本发明提供了一种电网基建用防倾倒合梯及使用方法，属于电网基建技术领域。本发明包括四个限位机构和涨缩机构。四个梯立柱分别一一对应放置在四个凹槽内时，操作人员向下按压梯立柱，梯立柱对涨缩机构施加向下的压力后，涨缩机构体积增大，带动限位机构远离梯立柱的一端向远离梯立柱中轴线的方向运动，以使限位机构与凹槽贴合，使得主梯和副梯在操作人员工作的情况下不发生位置移动，解决了现有技术中梯立柱与地面接触的稳定性较差，合梯容易倾倒的技术问题。
