The invention belongs to the technical field of climbing ladders, in particular to a foldable climbing ladder. The ladder mainly comprises a support, a handrail, a pedal plate, a limiting mechanism, adrawing piece and the like, the support comprises a folding support and a fixed support; the folding support comprises an upper support and a lower support; a handrail is arranged on the folding support; the handrails on the upper support and the lower support are fixed with the pedal through index pins; an upper support of the folding ladder is fixed to the front wall of the cabin body and connected with the lower support through a pin shaft, overturning and folding of the lower support are achieved, the lower support is folded to the proper position of the upper support and then limited through a stop pin, the locking performance of the folding ladder is guaranteed, occupied space of pedals and handrails is small after the climbing ladder is folded, and the upper support and the lower support are folded into a whole. The folding ladder solves the problems that an existing climbing ladder is large in size, complex to use, poor in use feeling and poor in safety, and can be widely applied to climbing occasions of various equipment cabins.
本发明属于登顶梯技术领域,具体涉及一种可折叠登顶梯,主要包括支座、扶手、脚踏板、限位机构、抽拉件等,支座包括折叠支座和固定支座,折叠支座又包括上支座和下支座,折叠支座上设置有扶手,上支座和下支座上的扶手与踏板使用分度销进行固定,折叠梯上支座固定与舱体前壁,与下支座通过销轴联接,实现下支座的翻转与折叠,下支座折叠到上支座的合适位置后用止动销进行限位,保证折叠梯的锁紧性能,登顶梯折叠后踏板与扶手所占空间很小,上支座与下支座折叠为一体。该折叠梯解决了现有登顶梯体积较大、使用繁琐、使用感差以及安全性差的问题,可以广泛应用于各类设备舱的登顶场合。
