The invention belongs to the field of portal cranes, particularly relates to a movable positioning structure of a shipbuilding portal crane, and aims to solve the problems that accessories need to be frequently moved in the shipbuilding process of an existing portal crane, the positions are difficult to stabilize after movement, the positioning efficiency is low, the stability of the accessories is low, and the accessories are prone to shaking during movement. According to the scheme, the lifting device comprises a portal frame, a moving seat, an electric hoist, a lifting hook and a positioning assembly, a moving hole is formed in the top of the portal frame, the moving seat is slidably installed in the moving hole, the electric hoist is fixedly installed at the bottom of the moving seat, and the lifting hook is fixedly connected to the electric hoist; and the positioning assembly is arranged on the electric hoist. According to the gantry crane, in the shipbuilding process, the positions of the parts after movement can be stabilized, the positioning efficiency is high, the stability of the parts is high, and the parts cannot greatly shake during movement.

    本发明属于门式起重机领域,尤其是一种造船门式起重机的移动定位结构,针对现有门式起重机在进行造船过程中需要频繁移动配件,而移动后难以稳定位置,定位效率较低,且对配件的稳定性较低,配件在移动时容易发生晃动的问题,现提出如下方案,其包括龙门架、移动座、电动葫芦、吊钩和定位组件,所述龙门架的顶部开设有移动孔,所述移动座滑动安装在移动孔内,所述电动葫芦固定安装在移动座的底部,所述吊钩固定连接在电动葫芦上,所述定位组件设置在电动葫芦上。本发明的门式起重机在进行造船过程中,可稳定配件移动后的位置,定位效率较高,且对配件的稳定性较高,配件在移动时不会发生大幅度晃动。
