Detection mechanism and measurement method of swing angle of double spreader bridge crane based on photosensitive element

Abstract

The invention discloses a detection mechanism and a measurement method for the swing angle of a double-sling bridge crane based on a photosensitive element, comprising: a detection slider arranged on a swing frame, and the detection slide block moves along the slideway of the swing frame along with the swing of the suspension rope The photosensitive element detection unit is arranged inside the detection slider; the first photosensitive element detection unit will move along with the motion of the detection slider, and the light emitted by the light source will irradiate the photosensitive element detection unit through the slit plate, and the movement of the pendulum angle will be controlled by the light. The signal is converted into a voltage signal output and pulse counted to measure the swing angle of the hanging rope; the angle of detection slider movement is equal to the number of electric pulses output by the photosensitive element, and the total number of pulses is equal to the number of openings on the gap plate. The invention solves the problem of detection of the swing angle of the bridge with double lifts and double spreaders, has simple structure, low cost, convenient maintenance, strong anti-interference ability, is not affected by weather, has high precision and is convenient for measurement, and can be directly measured without tedious component measurement. is the magnitude of the pendulum angle of the resultant force.

Description

technical field [0001] The invention relates to the fields of optics, electrical equipment and electrical engineering, in particular to a detection mechanism and measurement method for the swing angle of a double-sling bridge crane based on a photosensitive element. Background technique [0002] With the deepening of globalization and the continuous development of world trade, the rapid development of the container shipping industry has been driven. The scale of the port is also continuously expanding. As the key equipment for container operations in the port, the bridge crane's working capacity determines the cargo handling capacity of the terminal. The double spreaders of the double lifting bridge crane can load and unload two different containers at the same time, which greatly improves the transportation efficiency of the container terminal. However, due to some practical reasons (equipment loss, friction between equipment) and external environment and other factors dur...
