The invention relates to the technical field of building construction, and discloses a heavy tower crane device for building construction, which comprises a base frame, one side of a bearing arm is fixedly connected with a maintenance platform, one end of the bearing arm close to the base frame is rotatably connected with a safety door, and one side of the top of the safety door close to the maintenance platform is fixedly connected with a sleeve. A threaded rod of a hollow structure is slidably connected into the sleeve, sleeve plates corresponding to the wind cups in number are fixedly connected to the bottom of the transmission frame, the ends, away from the transmission frame, of the sleeve plates are sleeved with movable blocks in sliding connection, and the ends, away from the transmission frame, of the movable blocks are rotatably connected with hooks. In the process of opening the safety door, the threaded rod can extend out of the sleeve, and the rotating hook can be hung on the threaded rod at the moment, so that the safety door is limited, a worker cannot open the safety door, and it is ensured that the worker can only conduct overhaul work in a safe environment.
本发明涉及建筑施工技术领域,公开了一种建筑施工用重型塔吊装置,包括基架,承重臂的一侧固定连接有检修平台,承重臂上靠近基架的一端转动连接有安全门,安全门顶部靠近检修平台的一侧固定连接有套管,套管内滑动连接有空心结构的螺纹杆,传动架的底部固定连接有与风杯数量对应的套板,套板远离传动架的一端均套设有滑动连接的活动块,活动块远离传动架的一端均转动连接有挂钩,此建筑施工用重型塔吊装置,在安全门打开的过程中,螺纹杆会从套管内伸出,而此时转动的挂钩会挂在螺纹杆上,以此对安全门进行限位,使工作人员无法打开安全门,确保工作人员只可在安全环境下进行检修工作。
