[0002] In recent years, accidents caused by gusts in large port lifting equipment have occurred frequently, bringing significant economic losses to enterprises. In terms of typhoon prevention, due to reliable meteorological information and perfect typhoon prevention devices, the probability of accidents is relatively low. However, for sudden gusts, there are the following difficulties: gusts are unpredictable, have a small occurrence range, short duration, and strong wind force in a short time, which brings great difficulties to the wind prevention management of port lifting equipment. For the equipment in operation, the wind prevention emergency measures are relatively primitive, and the lives of employees and the property of enterprises are difficult to guarantee. Traditional rail clamps need to be manually controlled by workers. At the same time, in the case of a power outage, the electrically controlled rail clamps cannot further control the clamping operation, resulting in property losses. At the same time, when the wind speed is relatively high, the distance between the rail clamps cannot be adjusted, resulting in unstable clamping. To solve the above problems, an anti-gust control device for a gantry crane that can be automatically controlled, manually controlled in case of emergencies, and can adjust the distance between the rail clamps is required.
