The invention provides a lifting appliance for assembling a liquid rocket. The lifting appliance comprises a lifting supporting unit, a beam body connecting unit, an adjusting unit and two cross beamsling units. The lifting supporting unit is used for being connected with a lifting machine, the two ends of the beam body connecting unit are connected with the lifting supporting unit and the crossbeam sling units respectively, the adjusting unit is connected to the beam body connecting unit in series, and the cross beam sling units are used for being connected with a lifting point of a rocketto be lifted. In the rocket lifting process, the adjusting unit adjusts the positions of the cross beam sling units according to tension borne by the beam body connecting unit, so that the two cross beam sling units are evenly stressed. The lifting supporting unit comprises a first longitudinal beam, a first fork frame and a first lifting belt connected with the first fork frame are arranged on the first longitudinal beam, the first longitudinal beam is provided with a first fixing hole and a first adjusting hole, and the first lifting belt is used for being connected with the lifting machinein a hanging mode in the rocket lifting process. Before rocket connection and when the rocket is hoisted, the stress of the lifting point is accurately determined, and the risk that the rocket slidestowards the unbalance loading end is avoided.
本发明提供一种用于液体火箭组装的吊具,包含起吊支撑单元、梁体连接单元、调节单元、两个横梁吊索单元;所述起吊支撑单元用于连接起吊机,所述梁体连接单元的两端分别连接起吊支撑单元和横梁吊索单元,调节单元串联于梁体连接单元,横梁吊索单元用于连接待起吊火箭的起吊点;在起吊火箭的过程中,调节单元根据梁体连接单元所受到的拉力调节横梁吊索单元的位置,使两个横梁吊索单元受力均匀,起吊支撑单元包含第一纵梁,第一纵梁上设有第一叉架和连接所述第一叉架的第一吊带,第一纵梁设有第一固定孔和第一调节孔,第一吊带用于在起吊火箭过程中与起吊机挂接;在火箭连接前及吊装火箭精确地确定起吊点的受力,避免产生向偏载端滑动的风险。
