[0002] A climbing frame is a support set up at construction sites for workers to operate and solve vertical and horizontal transportation. It is a new type of scaffolding system developed in recent years. It is mainly used in high-rise shear wall buildings and can climb up or down along the building.

[0003] However, in the existing technology, the existing ladder base is fixed to the surface of the building by bolts, and the steel rope roller is driven by a motor to reel in the steel rope, so that the lifting platform can move along the ladder. However, damage to the driving device or rust and breakage of the steel rope can easily cause the lifting platform to fall, resulting in construction accidents for workers. Therefore, it is necessary to brake and lock the lifting platform on the ladder surface, and the lifting platform can be stabilized on the ladder surface by rotating the locking wheel, thereby preventing the lifting platform from falling.

[0004] Therefore, we need an anti-fall braking mechanism for super-high-rise intelligent internal and external climbing frames, which can solve the problem of anti-fall braking of the existing ladder surface lifting platform during the lifting process, and can also realize emergency braking and locking of the ladder surface lifting platform when it falls suddenly.

[0029] In actual use, the surface of the roller support 3 is fixedly connected to the inner surfaces of the two side plates of the lifting platform 2, and the surface of the roller support 3 is movably connected to the surface of the limiting guide groove 19, so that the lifting platform 2 plays a limiting role when it moves along the surface of the ladder body 1, and the surface of the limiting guide groove 19 is fixedly connected to the inner surface of the rack 9, and the teeth of the rack 9 are meshed with the teeth of the rotating gear 6.

When the lifting platform 2 suddenly falls on the surface of the ladder body 1, the rotating gear 6 drives the transmission gear 8 and the limit turntable 11 to rotate, so the cam 14 is driven to rotate along the stabilizing shaft 13 by the elastic force of the torsion spring 16, so that the end of the cam 14 is stuck between the limit turntable 11 and the limit clamping rod 12, so that the rotating gear 6 cannot roll on the surface of the rack 9, which has a braking locking effect on the lifting of the lifting platform 2.
