[0002] In the construction industry, the aluminum alloy formwork system has been widely used, and the aluminum alloy formwork unit components have been standardized and modularized. Usually, the width of the aluminum alloy formwork unit plate is within 500mm. When the concrete pouring is completed and the demolding conditions are met, the wall column and floor aluminum alloy formwork unit plates, support rods, quick-release joints, pull rods and other components are removed and transported to the upper floor for use. At present, basically, the removed aluminum alloy formwork components are transported to the upper floor by workers hand-to-hand through the reserved material transfer port on the floor. The existing method of hand-to-hand transfer by workers has the following problems: first, the workers work for a long time with high labor intensity, and the workers are prone to fatigue and distraction, which is not conducive to the physical and mental health of the workers and increases the safety risk of the operation; second, the workers hand-to-hand transfer of materials has low work efficiency and is not conducive to the advancement of the project progress; third, in the process of handing over the aluminum alloy formwork components, there is a risk that the upper personnel cannot hold the materials steadily and make mistakes, causing the transferred formwork components to fall, causing the personnel below to be hit by falling objects, and there is a great safety risk.
