The invention provides an elevator shaft internal operation method and an elevator shaft top layer platform device. The elevator shaft top layer platform device comprises an inner frame, an outer frame, a door opening cross beam and two door opening vertical rods; a strip-shaped fixing sleeve is arranged on the inner frame, the two sides of the inner frame are each provided with a side drawing part, each side drawing part comprises a telescopic rod used for being inserted into the corresponding strip-shaped fixing sleeve and a fixed cross beam fixed to the tail end of the telescopic rod and connected with the telescopic rod, and a lifting lug is arranged on each fixed cross beam; and the elevator shaft top layer platform device further comprises a fixing plate used for connecting the inner frame and the outer frame. By arranging the inner frame and the outer frame, and arranging a hook, the fixed cross beam, the lifting lug, the telescopic rod and the strip-shaped fixing sleeve on the inner frame, the inner frame can extend into an elevator shaft during use, the inner frame is fixed by utilizing the structure of the hook and the lifting lug after the side drawing parts on the two sides are pulled outwards, so that a worker treads on the telescopic rod, the strip-shaped fixing sleeve and the inner frame during operation, the worker can operate more conveniently, and the safety is improved.

    本发明提供一种电梯井内部作业方法及电梯井道顶层平台装置,该装置包括内架、外架、门洞横梁及两个门洞竖杆;内架上设有条形固定套,内架的两侧分别设有一个侧抽拉部件,侧抽拉部件包括用于插入条形固定套内的伸缩杆,和固定在伸缩杆末端并与伸缩杆连接的固定横梁,固定横梁上设有吊耳;还包括用来连接所述内架和外架的固定板;通过设置内架、外架,并在内架上设置挂钩、固定横梁、吊耳、伸缩杆及条形固定套可以在使用时将内架伸入电梯井内部,并将两侧的侧抽拉部件向外拉动之后利用挂钩和吊耳的结构对内架进行固定,从而在工人作业时踩踏在伸缩杆、条形固定套及内架上,这样既使工人作业更加方便也提高了安全性。
