The invention discloses a hydraulic jacking hatch cover crane, and relates to the technical field of hoisting equipment. The hydraulic jacking hatch cover crane comprises two supporting bases, a lifting appliance, a hatch cover and a guide rail; the upper parts of the two supporting bases are fixedly connected with hydraulic oil cylinders through bolts; the two sides of the lifting appliance are fixedly connected with connecting arms; the two connecting arms are fixedly connected to the upper ends of the hydraulic oil cylinders; and the two sides of the lower surface of the lifting appliance are each fixedly connected with two lifting hooks. According to the hydraulic jacking hatch cover crane, the hydraulic oil cylinders, the connecting arms and the lifting appliance are cooperatively arranged, so that the dangerous situation that a rope is corroded and broken in the using process of a traditional hatch cover crane is avoided, effective post-event reaction time is provided, workers are able to remind each other to pay attention on avoidance, and convenience is brought to temporary shutdown maintenance; and limiting seats, fixing plates and rollers are matched, so that the liftingappliance, the lifting hooks and the hatch cover are prevented from shaking greatly, and the stability and safety of the hatch cover during hoisting are improved.

    本发明公开了液压顶升舱盖吊,涉及起重设备技术领域,包括两个支撑底座、吊具、舱盖以及导轨,两个支撑底座的上部通过螺栓固定连接有液压油缸,吊具的两侧均固定连接有连接臂,两个连接臂通过销轴固定连接在液压油缸的上端,吊具下表面的两侧均固定连接有两个吊装弯钩。本发明通过液压油缸、连接臂以及吊具之间的配合设置,避免出现传统舱盖吊在使用过程中绳索锈蚀断裂的危险情况,提供有效的事后反应时间,有助于工作人员互相提醒注意避让,这也为临时停机维修带来便利,通过限位座、固定板以及滚柱之间的配合设置,避免吊具、吊装弯钩以及舱盖发生大幅度的晃动,提高舱盖在吊运时的稳定性和安全性。
