Lifting device and method for braided net

The invention discloses a lifting device and method for a braided net. The device comprises a conductive component and a connecting plate. A first hanging point and a plurality of second hanging points are arranged on the connecting plate; the first hanging point is used for being connected with the conductive component; the second hanging points are used for being connected with the braided net;when the conductive component bears tension, the conductive component drives net knots of the braided net to bear force, and thus the length of the braided net is increased. According to the lifting device and method, the pre-tensioning force in the braiding process of the braided net can be loaded, so that rope knots of the braided net are in the tension state. Therefore, in the use process, thebraided net can be prevented from generating irregular deformation or the length of the braided net can be prevented from becoming longer due to uneven force, normal use is ensured, and the occurrencerate of accidents is great
