Overturn-preventing falling-preventing attached lifting scaffold

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.

Description

Technical field [0001] The invention relates to a scaffold, in particular to an attached lifting scaffold. Background technique [0002] With the rapid development of the domestic construction industry, there are more and more high-rise and super high-rise buildings in the city. In the construction process, attached lifting scaffolding is usually used to achieve the purpose of high-rise construction. Due to the high height of high-rise scaffolding, it is prone to overturning and falling. Accidents cause safety accidents. The existing attached lifting scaffolds are generally provided with anti-overturning devices and anti-falling devices separately, resulting in a complex structure of the scaffold. Moreover, the structure of the traditional anti-falling device is more complex, with many springs and other parts. Damage to one of the components will cause the failure of the anti-falling device, the reliability and safety of use are low, and the complex structure increases the manufa...

Problems solved by technology

[0002] With the rapid development of the domestic construction industry, there are more and more high-rise and super high-rise buildings in the city. During the construction process, the purpose of high-rise construction is usually achieved through attached lifting scaffolding. Due to the high height of high-rise scaffolding, it is easy to overturn and fall. Accidents, resulting in safety accidents, the existing attached lifting scaffolds are generally equipped with anti-overturning devices and anti-falling devices separately, resulting in a complex structure of the scaffolding, and the structure of the traditional anti-falling device is more complicated, and there are many parts such as springs. Once the springs, etc. Damage to one of the parts will cause the failure of the anti-fall device, the reliability and safety of use are low, and the complex structure increases the manufacturing cost of the anti-fall component, which is not conducive to market promotion and use

To sum up, lifting scaffolds have potential safety hazards during use, while traditional anti-drop components have complex structures, low reliability and safety, and high manufacturing costs, which are not conducive to market promotion and use.
