The invention discloses a shipbuilding portal crane adopting a mass damper. The shipbuilding portal crane adopting the mass damper comprises a mass block, elastic assemblies and a rack, the mass block is arranged in the center of the rack through the elastic assemblies, and the elastic assemblies comprise the first elastic assembly, the second elastic assembly, the third elastic assembly, the fourth elastic assembly, the fifth elastic assembly and the sixth elastic assembly. The first elastic assembly, the second elastic assembly, the third elastic assembly, the fourth elastic assembly, the fifth elastic assembly and the sixth elastic assembly are all arranged between the mass block and the rack. The shipbuilding portal crane adopting the mass damper is simple in overall structure and low in manufacturing cost, vibration of the whole crane is effectively reduced, meanwhile, center-of-gravity shift of the whole crane is reduced, the overhaul frequency is reduced, and therefore the use cost is greatly reduced.

    本发明公开了一种采用质量阻尼器的造船门式起重机。采用质量阻尼器的造船门式起重机包括质量块、弹性组件和机架,质量块通过弹性组件设置在机架中心部位,其中:弹性组件包括第一弹性组件、第二弹性组件、第三弹性组件、第四弹性组件、第五弹性组件和第六弹性组件,第一弹性组件、第二弹性组件、第三弹性组件、第四弹性组件、第五弹性组件和第六弹性组件均设置在质量块与机架之间。本发明采用质量阻尼器的造船门式起重机整体结构简单,造价低廉,有效降低了整机振动,同时减小整机重心偏移,减小了检修频率,从而大大减少了使用成本。
