The invention relates to the technical field of rail-mounted gantry crane hoisting, in particular to a rail-mounted gantry crane main beam hoisting process which comprises the following steps that rail-mounted gantry crane main beams are spliced in the direction parallel to a cart rail, and the main beams comprise the first main beam and the second main beam; the current first center-of-gravity position of the first main beam and the second center-of-gravity position after landing of the landing leg are calculated, a truck-mounted crane is arranged according to the first center-of-gravity position and the second center-of-gravity position, and the truck-mounted crane integrally lifts the first main beam to exceed the position above the landing leg and then turns to be aligned with the center of the landing leg to be located; calculating a current third gravity center position of the second main beam and a fourth gravity center position after the landing leg is located, arranging a truck crane according to the third gravity center position and the fourth gravity center position, lifting the second main beam by the truck crane, steering below the first main beam, integrally lifting to exceed the position above the landing leg, steering again, and aligning with the center of the landing leg to be located. According to the hoisting process, the influence on the wharf flood prevention embankment is reduced, and the flexibility and adaptability of the hoisting process are improved.
本发明涉及轨道吊吊装技术领域,尤其涉及一种轨道吊主梁吊装工艺,包括以下步骤:将轨道吊主梁平行于大车轨道方向进行拼装,主梁包括第一主梁和第二主梁;计算第一主梁当前的第一重心位置以及落位支腿后的第二重心位置,根据第一重心位置和第二重心位置布置汽车吊,汽车吊整体提升第一主梁超过支腿上方后转向,与支腿中心对齐落位;计算第二主梁当前的第三重心位置以及落位支腿后的第四重心位置,根据第三重心位置和第四重心位置布置汽车吊,汽车吊提升第二主梁并在第一主梁下方转向,整体提升超过支腿上方再次转向,与支腿中心对齐落位。该吊装工艺减少了对码头防汛堤的影响,并提高了吊装工艺的灵活性和适应性。
