High-altitude construction operation device and operation machine thereof

The high-altitude construction operation device comprises a first frame body assembly, the first frame body assembly comprises a supporting frame, an operation platform, a movable connecting mechanism, a ladder and a locking mechanism, and the operation platform is provided with a first operation position and a second operation position which are different in horizontal height; the ladder can correspondingly adjust the position according to the operation platform. Operating positions of different horizontal heights are achieved through the rotatable operating platform, the operating height can be adjusted by rotating the operating platform, the requirement for different-height construction of an operator is met, the platform does not need to be built again, the operator can move among platforms of different heights through the height-adjustable ladder, and the working efficiency is improved. The number of needed platforms is reduced, the height of the operation platform is adjusted more flexibly, the operatio
