Description

A New Lifting Construction Scaffolding

technical field

The invention relates to the field of construction engineering, in particular to construction scaffolding.

Background technique

Scaffolding is a variety of supports erected for workers' operation, safety, and vertical and horizontal transportation. It is generally used in places where exterior walls, interior decoration, or high floor heights cannot be directly constructed. After the building is put into use, due to various reasons, the outer wall needs to be repaired due to damage. Due to reasons such as height and cost, it cannot be repaired in time. At present, portal scaffolding is often used for small-scale maintenance and construction of low-altitude exterior walls. Although this kind of portal scaffolding is convenient to build, its height cannot be adjusted flexibly, and it is difficult to meet the requirements of multiple height operations; and with the increase of the height of portal scaffolding, the chassis area will not increase, resulting in unstable center of gravity, there is Certain security risks. In addition, the working platform of the existing scaffolding is often not expandable and cannot reach certain construction positions, causing inconvenience in use.

Therefore, how to improve the existing building scaffolding to overcome the above problems is a problem to be solved urgently by those skilled in the art.

Contents of the invention

The main purpose of the present invention is to provide a new type of lifting scaffold that can be lifted and lowered flexibly, and is safe, stable, fast and efficient. In addition, the working platform of the scaffold provided by the present invention can be further expanded to more flexibly meet the requirements of different construction positions.

In order to achieve the above purpose, the technical solution adopted by the present invention is: a new type of lifting construction scaffolding, including a chassis assembly, a lifting assembly, a workbench assembly and a power assembly, and the lifting assembly is arranged on the chassis assembly and the workbench. Between the components, it is used to realize the rise and fall of the workbench component, the power component is arranged on the chassis component, and is used to provide the power for the lift component to rise and fall, and the lower end of the lift component is set in linkage On the chassis assembly, it is used to realize that the floor area of the chassis assembly increases when the lifting assembly rises, and the floor area of the chassis assembly decreases when the lifting assembly descends. The chassis components can expand and expand with the rise of the workbench components, thereby making the scaffold more stable and further ensuring the safety of the construction; the linkage between the chassis components and the lifting components also provides a more convenient and quick way to stabilize the scaffold chassis. In this way, the two parts can be operated with one power, without step by step, so as to further improve the work efficiency.

Preferably, the lifting assembly is a scissor-type lifting structure, including lifting rods arranged crosswise and connecting shafts arranged between the lifting rods; the chassis assembly includes a bottom plate, a linkage rod, a horizontal telescopic tube, Rod, longitudinal telescopic tube and longitudinal telescopic rod, the horizontal telescopic tube is slidably connected to the base plate, the horizontal telescopic rod is sleeved in the horizontal telescopic tube, the longitudinal telescopic tube is slidably connected to the bottom plate and Perpendicular to the horizontal telescopic tube, the longitudinal telescopic rod is sleeved in the longitudinal telescopic tube; the linkage rod is arranged between the lifting rod and the horizontal telescopic tube, the horizontal telescopic rod, between the pipe and the longitudinal telescopic rod; it is used to realize that when the lifting assembly rises, the lifting rod at the lower end of the lifting assembly moves closer to the middle, driving the linkage rod to move, and then driving the horizontal telescopic tube and the horizontal telescopic rod to slide to the lateral sides, driving the longitudinal telescopic pipe and the longitudinal telescopic rod to slide to the longitudinal two sides, finally realizing the increase of the footprint of the chassis assembly; when the lifting assembly is lowered, the The lifting rod at the lower end of the lifting assembly slides to both sides, driving the linkage rod to move, and then driving the horizontal telescopic tube and the horizontal telescopic rod to move closer to the middle of the horizontal direction, driving the vertical telescopic tube and the longitudinal The telescopic rod moves closer to the middle of the longitudinal direction, finally realizing the reduction of the footprint of the chassis assembly. The scissor principle is used to realize the linkage between the lifting component and the chassis component.
