Abstract
The invention discloses an overturn-preventing falling-preventing attached lifting scaffold, comprising a frame body and a guide base. The rear side surface of the frame body is provided with at least two overturn-preventing lifting rails. The overturn-preventing lifting rail comprises guide rail components and support pillars supported between the guide rail components. The front side surface of the guide base is provided with an overturn-preventing guide wheel assembly cooperated with the guide rail components. The lower side surface of the guide base is provided with a falling-preventing assembly cooperated with the support pillars. When the frame body goes up and down, the rails move up and down along the guide wheels. The guide wheels prevent the rails from offset, so that the frame body goes up and down in a straight line. In a lifting process, if an accident occurs and the frame body falls down in a normal speed, a falling-preventing block would swing to the outer side of the support pillars by self-weight, and does not block or support the support pillars, and the frame body can fall down normally, if the frame body falls down in unnormal speed, the falling-preventing block does not have enough time to swing between the support pillars, so the falling-preventing block blocks and supports the support pillars, thereby effectively preventing the frame body from falling. The scaffold integrates overturn prevention and falling prevention, and structure and operation are simplified.
