The invention relates to the technical field of hoisting equipment, in particular to a port gantry crane which comprises supporting legs, a cross beam and a hoisting table. The upper end of the cross beam is movably connected with the hoisting table, the lower end of the hoisting table is telescopically connected with a lock head, the lower end of the cross beam is fixedly connected with the supporting legs, and four sets of the supporting legs are arranged. The supporting legs are located at the four corners of the cross beam. When the crane lifts goods, the cables in four sets of anti-swing boxes position the lock head in four directions, and when the goods are lifted up, the four sets of the cables are in a tightened state under the gravity action of the anti-swing boxes and the limiting action of the sliding grooves on the sliding blocks. And upward acting force is generated on the anti-swing boxes through the cables, and the anti-swing boxes and the goods synchronously move upwards along the sliding grooves under the action of the sliding blocks, so that the goods are prevented from shaking under large wind force, shaking of the goods under the action of wind is reduced, and the safety coefficient of the gantry crane is increased.

    本发明涉及吊运设备技术领域,尤其是涉及一种港口龙门起重机,包括支腿、横梁、起吊台,所述横梁上端活动连接有起吊台,所述起吊台下端通过伸缩连接有锁头,所述横梁下端固定连接有支腿,所述支腿数量为四组,且其分别位于横梁的四角处,当起重机起吊货物时,四组防摆箱内部的缆绳将锁头通过四个方向缆绳对锁头进行定位,在货物起吊同时,四组缆绳受到防摆箱自身的重力作用以及滑槽对滑块限制作用下,四组缆绳为紧绷状态,并通过缆绳对防摆箱产生向上的作用力,并使得防摆箱在滑块的作用下沿着滑槽与货物同步向上运动,从而防止货物受到较大风力出现摇晃,减小货物在风的作用下出现晃动,提高龙门吊的安全系数。
