The invention relates to a gantry crane overturn-preventing protection device and a using method thereof. The protection device comprises a drum rotatably mounted on a bottom beam, a first inhaul cable wound on the drum, a second inhaul cable wound on the drum, and a locking mechanism mounted on the bottom beam and arranged corresponding to the drum, wherein the arrangement direction of the firstinhaul cable is consistent with the traveling direction of a gantry crane, the first inhaul cable is in a tightened state, the winding direction of the second inhaul cable is opposite to the winding direction of the first inhaul cable, the second inhaul cable and the first inhaul cable are arranged on the two sides of the drum, the arrangement direction of the second inhaul cable is consistent with the traveling direction of the gantry crane, the second inhaul cable is in a tightened state, and the locking mechanism can clamp the drum and limit rotation of the drum. The first inhaul cable andthe second inhaul cable are wound on the drum in the opposite directions and can cooperate with movement of the gantry crane to be always in the tightened state to pull the gantry crane, and the overturn-preventing effect on the gantry crane is achieved.

    本发明涉及一种龙门吊防倾覆保护装置及其使用方法,保护装置包括:可转动地装设于底梁上的卷筒;缠绕于卷筒上的第一拉索,且第一拉索的设置方向与龙门吊的行走方向相一致,第一拉索处于绷紧状态;缠绕于卷筒上的第二拉索,第二拉索的缠绕方向与第一拉索的缠绕方向相反,第二拉索和第一拉索设于卷筒的两侧,第二拉索的设置方向与龙门吊的行走方向相一致,第二拉索处于绷紧状态;安装于底梁上并对应卷筒设置的锁紧机构,可夹紧卷筒并限制卷筒的转动。本发明的第一拉索和第二拉索以相反方向缠绕于卷筒上,可配合龙门吊的移动而始终处于绷紧状态拉住龙门吊,对龙门吊起到防倾覆的作用。
