The purpose of the present invention is to propose an automatic detection device for safety nets, which can be used for the detection of safety nets, and reduce manual intervention, so as to reduce labor intensity and improve accuracy. The safety net automatic detection device includes a bracket, an impact hammer and an automatic tensioning mechanism for hanging and adjusting the tension of the safety net. The tightening mechanism includes a frame fixed on the bracket, hooks are installed around the frame, and the hooks on at least two adjacent sides of the frame are movable hooks, and each movable hook is connected with a tension device . The safety net automatic detection device of the present invention is designed according to the requirements of the "National Standard of the People's Republic of China GB5725-2009" "Safety Net Impact Resistance Test", except for the manual operation of hanging the net and removing the net, it is all automatically completed, improving In order to improve the efficiency and accuracy, it is very suitable for the detection of safety nets.
Description
technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to an automatic detection device for a safety net. Background technique [0002] The safety net is a protective net set under or on its side during building construction, equipment installation or skill performances at high altitudes to prevent accidents caused by people or objects falling. The safety net is composed of a net body and side ropes. The net body is braided by net ropes and has a rhombus or square mesh. The distance between two adjacent knots of the braid is called the mesh size; the net rope on the edge of the net body is called the side rope. The size (nominal size) of the safety net is determined by the size of the side rope. [0003] The strength of the safety net is directly related to the protection effect, so it must be detected, and there is no special device for detecting the safety net at present. Contents of the invention [0004...
