The invention aims to disclose an automatic detection device for a safety net, and the automatic detection device is used for detecting the safety net and reducing manual intervention to reduce labor intensity and improve accuracy. The automatic detection device comprises a bracket, an impact hammer and an automation tensioning mechanism used for hanging and adjusting the tension degree of the safety net, wherein the impact hammer is suspended on the bracket in a manner of moving up and down through a hoisting mechanism; the automatic tensioning mechanism comprises a frame fixed to the bracket; hooks are mounted at the periphery of the frame; the hooks on at least two adjacent side edges of the frame are movable hooks; a tension device is connected to each movable hook. The automatic detection device is designed based on the requirements of 'impact resistance tests of safety nets' of <the State Standard of the People's Republic of China GB5725-2009>; all operations except for net hanging and dismounting operations are automatically finished, so that the efficiency and the precision are improved; the automatic detection device is very suitable for detecting the safety net.
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.
