Description

Technical Field

[0001] The utility model relates to the technical field of aerial work, in particular to an aerial work platform. Background Art

[0002] An aerial work platform is a piece of equipment specifically designed for working at heights, helping workers to safely perform maintenance, installation, and other work at height.

[0003] For example, the patent with the national authorized patent announcement number CN209396845U discloses an aerial work platform, whose structure includes a top supporting plate, a front control wheel, a control box, a rear control wheel, a connecting fixed rod, a supporting vertical rod, a telescopic extension rod, a guardrail spare operation grid, and a guardrail. The front control wheel is installed at the bottom end of the top supporting plate. The utility model is an aerial work platform. When operating on the guardrail spare operation grid, if the center is suddenly unstable and leans against the guardrail, when the guardrail cannot withstand the pressure, it will tilt outward. When the guardrail tilts, it will drive the card wheel to rotate, so that the card wheel will push the force-bearing card pattern upward through its own texture. When the force-bearing card pattern moves to a certain position, the tilting card rod will squeeze the return spring to pop out from the protective shell, and the extrusion spring will help it to bounce up more quickly. The force-bearing extrusion seat is stuck inside so that it will not shake. When an accidental danger occurs to the guardrail, the internal spare guardrail can be quickly extended to protect people.

[0004] However, the above-mentioned aerial work platform cannot extend the height of the fence according to the height of the workers, which will result in the workers not being fully protected during work. For taller workers, the fixed height guardrail cannot effectively prevent them from accidentally falling. Utility Model Content
