The invention discloses a construction aluminum formwork conveying device which comprises two support sets symmetrically arranged in the front-back direction. Each support set comprises a first longitudinal support, a second longitudinal support and a first transverse support, wherein a second transverse support is arranged below the first transverse support; the two ends of the second transverse support are connected with the first longitudinal support and a second connection shaft on the second longitudinal support through guide holes; and a touch switch is arranged in each guide hole. An upper drive mechanism is arranged between the upper portions of the right side faces of the first longitudinal support, and a lower drive mechanism is arranged between the lower portions of the right side faces of the first longitudinal support. An upper auxiliary wheel mechanism is arranged between the upper portions of the left side faces of the second longitudinal support, and a lower auxiliary wheel mechanism is arranged between the lower portions of the left side faces of the second longitudinal support. A tension spring is arranged between the bottom of the right side face of each first longitudinal support and the bottom of the left side face of the corresponding second longitudinal support. According to the conveying device, electromagnetic valves are triggered under action of the tension springs to make alternating current motors stop operating after all aluminum formworks pass through the lower drive mechanisms and the lower auxiliary wheel mechanisms, and workers on an upper floor can take away the aluminum formworks with little effort.
