The invention provides an elevator shaft internal operation method and an elevator car top platform system.The elevator shaft internal operation method comprises the following steps that S1, a fixed mounting plate is mounted at the top of an elevator car, and a scissor fork type lifting device is mounted above the fixed mounting plate; S2, a vertical crawling ladder is mounted above the fixed mounting plate; S3, workers enter a side protective fence, and a bottom plate is lifted; S4, the interior of an elevator shaft is maintained in the side protective fence; S5, moving is carried out along the vertical crawling ladder and maintenance work is carried out; and S6, the bottom plate descends, and the workers evacuate to complete all maintenance work. The scissor fork type lifting device is arranged at the top of the elevator car, a top protection plate, the side protective fence and the bottom plate are arranged above the scissor fork type lifting device, the workers can stand above the bottom plate during maintenance, the side faces and the tops of the workers are protected through the top protection plate and the side protective fence, and therefore safety can be improved; and meanwhile, the device has the effects of being convenient to install and capable of standardizing operation standards.

    本发明提供一种电梯井内部作业方法及电梯轿厢顶平台系统,该电梯井内部作业方法,包括如下步骤:S1:于电梯轿厢顶部安装固定安装板,并在固定安装板上方安装剪叉式升降装置;S2:于固定安装板上方安装竖直爬梯;S3:进入侧防护栅栏内部,并升降底板;S4:于侧防护栅栏内部对电梯井内部进行维修;S5:沿竖直爬梯移动并进行维修工作;S6:下降底板,工作人员撤离完成全部维修工作。在电梯轿厢顶部设置剪叉式升降装置,并在剪叉式升降装置上方设置顶部防护板、侧防护栅栏及底板可以在维修时让工作人员站在底板上方并利用顶部防护板和侧防护栅栏对人员的侧面和顶部进行防护,这样可以提高安全性,同时该装置具有安装方便且可以规范作业标准的作用。
