The invention provides a grab dredger I-shaped steel lifting transportation frame which comprises a frame body and transportation wheels arranged at the bottom of the frame body, and further comprises a chain block arranged at the top of the frame body and used for lifting operation. The side supports comprise vertical rods fixedly arranged on the side walls of the frame body and transverse rods symmetrically arranged on the two side walls of the vertical rods along the side faces where the vertical rods are located, and the balance weight mechanisms are fixedly arranged on the side walls of the transverse rods and comprise balance weight frames and balance weight blocks capable of vertically moving along the balance weight frames. When the I-shaped steel is unloaded, the transportation frame is pushed to the bottom of the I-shaped beam, the I-shaped steel is hoisted through the chain block, and when the I-shaped steel is hoisted through the hoisting end, the balancing weight is driven to move downwards along the balance weight frame, so that the center of the whole transportation frame is lowered; and meanwhile, the side supports can be driven to extend outwards from the inner sides of the transverse rods, so that the supporting area of the side supports is increased, and the operation stability during I-shaped steel lifting is improved.

    本发明提供一种抓斗船工字钢起落运输架,包括架体以及设置在架体底部的运输轮,还包括手拉葫芦,所述手拉葫芦设置在架体顶部,用于起吊作业,所述侧支架包括固设在架体侧壁的竖杆以及沿竖杆所在侧面对称设置在竖杆两侧壁的横杆,配重机构固设在横杆侧壁,且配重机构包括配重框架以及能够沿配重框架竖向移动的配重块,所述传递机构设置在手拉葫芦的起吊端与配重块之间,本发明中卸下工字钢时,将运输架推进至工字梁底部,通过手拉葫芦将工字钢吊起,在经过起吊端对工字钢吊起时,会带动配重块沿着配重框架下移,以降低该整个运输架的中心,与此同时可驱动侧支撑自横杆内侧向外伸出,以增加侧支撑的支撑面积以提高起吊工字钢时的作业稳定性。
