[0001] The utility model relates to the technical field of building climbing frame lifting, in particular to a lifting device for intelligent internal and external climbing frames of super high-rise buildings. Background Art

[0002] Climbing frame is also called lifting frame. According to its power source, it can be divided into hydraulic type, electric type, manual type and other main types. Climbing frame is a new type of scaffolding system developed in recent years. It is mainly used in high-rise shear wall buildings. It can climb up or down along the building.

[0003] However, in the existing technology, the lifting platform of the climbing frame uses a motor to reel in the wire rope, so that the lifting platform is pulled upward by the wire rope, and the lifting platform of the existing climbing frame is not easy to disassemble and separate from the climbing frame, and the wire rope of the driving device will rust and break after long-term use, causing the lifting platform to fall rapidly, thereby causing construction accidents, and it is necessary to enable the lifting platform to be able to brake urgently when it falls rapidly under the inertia of gravity.

[0004] Therefore, we need a lifting device for intelligent internal and external climbing frames of super high-rise buildings, which can solve the installation and disassembly problems between the existing lifting platform and the climbing frame, and can also realize emergency braking when the lifting platform falls rapidly. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting device for an intelligent internal and external climbing frame of a super high-rise building, so as to solve the installation and disassembly problems between the existing lifting platform and the climbing frame proposed in the above-mentioned background technology, and also to realize emergency braking when the lifting platform falls rapidly.

At the same time, when the installation card board is taken out from the installation card slot, it is convenient to disassemble the lifting platform. The retracting rod of the micro cylinder is retracted into its interior, so that the limit hook disengages, the limit torsion spring twists, and the braking hook rotates.

At the same time, when the mounting card plate 5 is taken out from the inside of the mounting slot 4, it is convenient to disassemble the lifting platform 2.
