Anti-falling lifting type scaffold
The invention relates to an anti-falling lifting type scaffold, and belongs to the technical field of building construction. The scaffold comprises a scaffold body fixedly connected with an anti-falling ladder rail; the anti-falling ladder rail is composed of a pair of vertical anti-falling rods crossed through the anti-falling device and a ladder rod fixed between the vertical anti-falling rods; the anti-falling device includes a supporting base, the supporting base supports a horizontal fixing shaft moveably sleeved with a spider gear, the spider gear is meshed with the ladder rod of the anti-falling device; the middle part of a fixing shaft is provided with a key groove penetrated in vertical direction, and a lock key is mounted in the key groove; the inner hole of the spider gear is provided with an interval ratchet hollow, and the interval ratchet hollow consists of a declining locking end and a curve transition section; the upper end of the lock key is provided with a pawl head, and the lower end of the lock key is provided with a contact head; when the pawl head is corresponding to the locking end, the contact head is corresponding to the transition section; when one of the pawl head and the contact head is extended out of the key groove, and the other one is returned to the key groove. The anti-falling lifting type scaffold ingeniously uses the gravity and weight loss, so that the pawl can play the locking function in the course of rapidly dropping. Therefore, the anti-falling performance is always stable and reliable even after using for a long time.
