Six-degree-of-freedom butt joint trolley of booster nose cone of carrier rocket

Abstract

The invention relates to a six-degree-of-freedom butt joint trolley of a booster nose cone of a carrier rocket. The trolley consists of a front bracket, a rear bracket, a front bracket rotating groove, a lateral moving frame, a rotating frame, a trolley frame, a wheel set and a rotating screw rod mechanism. The front bracket is used for supporting the front part of the booster nose cone and can roll in the front bracket rotating groove under the action of the rotating screw rod mechanism; the rear bracket is used for supporting the rear part of a booster and provided with rolling wheels, and the booster can roll on the rolling wheels of the rear bracket under the action of the rotating screw rod mechanism; lifting adjustment of the front bracket and rear bracket is achieved by lifting screw rod mechanisms; by adjusting the front and rear lifting screw rod mechanisms, the pitching adjustment of the booster along the axis can be achieved. The lateral moving frame can move laterally on the supporting surface of the rotating frame by a lateral lead screw mechanism, and thus the booster nose cone is transversely moved; the rotating frame can horizontally rotate around the central axis of the trolley frame, and correspondingly horizontal rotation adjustment of the booster nose cone is achieved. The wheel set is parked on a rail in a factory building and can be pushed along the rail,so that the forward and backward movement of the booster nose cone is achieved.

Description

technical field [0001] The invention relates to a six-degree-of-freedom docking car for a nose cone of a launch vehicle booster. Background technique [0002] The bundled launch vehicle usually consists of a multi-stage rocket body, a satellite fairing, and a booster. The booster body and nose cone need to be assembled before final assembly testing. The used butt support vehicle of existing rocket body horizontal assembly is usually a split type, that is, the front support vehicle and the rear support vehicle are separately arranged, not integrated. This type of docking support vehicle does not have the function of horizontally rotating the rocket body. When docking, the axes of the two rocket bodies cannot guarantee good consistency, and the end frame of the rocket body will bear a large additional bending moment, resulting in The frame is deformed. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides a six-degree-o...
