Description

Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to a portable and stable aerial work platform. Background Art

[0002] Working at heights is a dangerous task that requires high skills and expertise, as well as high safety measures and equipment to ensure the safety of workers and the efficiency of work. Structural construction is mostly done at heights, and workers need to cooperate with each other during high-altitude splicing and welding. There are many high-altitude suspended work scenes in engineering construction, and it is not convenient to use hanging baskets. For construction safety, climbing frame projects generally use scaffolding from the bottom, and scaffolding projects set up local cantilevers to build temporary and simple high-altitude operating platforms for workers. Traditionally, temporary operating platforms are made by workers using traditional welding methods to connect materials such as steel pipes or steel sections. Although this method of making temporary operating platforms has the advantage of simple installation work, its disadvantages are high on-site fire risks, and it is inevitable to cut materials during demolition work. After the demolition work, the constituent materials of temporary facilities are difficult to recycle, and the materials used to make temporary facilities can only be discarded once. Therefore, this method has the disadvantages of complex procedures, high cost, low efficiency, high safety risks, and inability to be reused. Utility Model Content

A support plate 5 is fixedly connected between the support rods 2 on the same side, and a limited height mechanism 6 is arranged on the top of the support plate 5. The height of the limited height mechanism 6 is adjustable. The working space above the working basket 1 can be adjusted by adjusting the height of the limited height mechanism 6 to provide additional safety protection to adapt to different construction needs. A baffle 9 is arranged on the top of the limited height mechanism 6. The baffle 9 can be fixedly connected to the limited height mechanism 6, or hinged to the top of the limited height mechanism 6 to prevent falling objects from high altitude from causing harm to construction workers.

[0025] As a further preference of this embodiment, the work basket 1 includes four mutually parallel vertical rods 11, and a plurality of cross rods 12 are fixedly arranged between adjacent vertical rods 11. The vertical rods 11 and the cross rods 12 are welded to form a frame structure of the work basket 1.

The size of the square limit plate 63 is slightly smaller than the internal cavity size of the height limit frame 61. The square limit plate 63 is used to limit the rising range of the height limit frame 61 to ensure safe operation.
