Intelligent safety monitoring system for bridge and gate type hoisting machinery

The utility model relates to an intelligent safety monitoring system for bridge and gate type hoisting machinery, which comprises a trolley distance measuring mechanism and a camera mechanism, and the trolley distance measuring mechanism comprises a distance measuring instrument arranged on an end beam of a crane and a distance measuring detection plate arranged on a transverse moving trolley. The camera mechanism comprises a mounting frame fixed on an end beam of the crane, an adjusting frame hinged on the mounting frame and a driving mechanism for driving the adjusting frame to swing left and right, and a camera and a spotlight facing the same direction as the camera are mounted on the adjusting frame. And the driving mechanism controls the left-right swing of the adjusting frame according to the left-right position of the transverse moving trolley, so that the camera is aligned with the crane hook below the transverse moving trolley, and the safety monitoring is carried out on the position of the crane hoo
