The invention relates to a double-layer folding landing door device for a construction hoist, which comprises a mounting frame, a plurality of fixing assemblies, a first landing door, a second landing door and a door picking assembly, and the mounting frame is fixedly connected with the plurality of fixing assemblies; in the actual use process of the construction hoist, the installation frame can be installed on a building through the fixing assembly, the door lifting assembly is installed on a cage door of the construction hoist, when the cage door of the construction hoist is opened, the cage door can drive the door lifting assembly to lift the first landing door firstly, so that the first landing door slides on the first sliding groove, and the second landing door slides on the second sliding groove. Then the second landing door is lifted up, the second landing door slides on the second sliding groove, before the construction elevator leaves, the cage door of the construction elevator is closed, meanwhile, the cage door gradually puts down the first landing door and the second landing door through the door lifting assembly, and therefore the landing doors can be opened when the construction elevator is started, and the landing doors can be closed when the construction elevator is closed; the use of a user is convenient, and potential safety hazards are eliminated.

    本发明涉及一种施工升降机用双层折叠式层门装置,包括安装框架、固定组件、第一层门、第二层门和挑门组件,安装框架上固定连接有若干个固定组件;在实际施工升降机使用过程中,可将安装框架通过固定组件安装于建筑物上,并将挑门组件安装于施工升降机的笼门上,当施工升降机的笼门开启时,可通过笼门带动挑门组件先将第一层门挑起,使第一层门在第一滑槽上滑动,随后将第二层门挑起,使第二层门在第二滑槽上滑动,在施工升降机离开前,施工升降机的笼门关闭,同时笼门通过挑门组件逐步将第一层门和第二层门放下,由此能够在施工升降机开启时层门开启,在施工升降机关闭时层门关闭,方便使用者的使用,并且消除安全隐患。
