Multifunctional butt joint frame vehicle capable of moving freely

Abstract

The invention belongs to the field of aircraft general assembly technology support systems. A multifunctional butt joint frame vehicle capable of moving freely comprises four single frame vehicles. The first-stage section and the second-stage section of an aircraft are parked on a first frame vehicle, a second frame vehicle and a third frame vehicle respectively, the height of the frame vehicles are adjusted through a universal wheel train, the two sections are made to be located at the same horizontal height, and the two sections are made to be located on the same axis through horizontal freemovement of the universal wheel train. The threaded ends of the two sections are close to each other, and the sections can roll in the circumferential direction through a rolling wheel system on a supporting bracket, so that rotary butt joint of the two sections is achieved. The second frame vehicle and the third frame vehicle are replaced with a fourth frame vehicle, the supporting brackets of the second frame vehicle and the third frame vehicle are removed, and a launching device is placed on the upper planes of the second frame vehicle and the third frame vehicle. The docked aircraft is moved to the front end of the launching device through the first frame vehicle and the fourth frame vehicle and is slowly propelled, and horizontal docking of the aircraft and the launching device is achieved. By the adoption of the multifunctional butt joint frame vehicle, the constraint that a rail assembly plant is needed can be thrown away, the guarantee conditions of a general assembly plant are reduced, and aircraft section-level rotary butt joint and horizontal butt joint work of the aircraft and the launching device are completed.

Description

technical field [0001] The invention belongs to the field of aircraft general assembly technical support systems, and in particular relates to a freely movable docking vehicle on the ground that realizes the functions of rotational docking of primary and secondary sections of an aircraft, and horizontal docking of an aircraft and a launching device. Background technique [0002] In the final assembly process of a commercial rocket company's aircraft, there are two important assembly processes: the docking of the primary and secondary sections and the docking of the aircraft and the launching device. The connection between the primary and secondary sections is a threaded rotary connection. The docking method is horizontal docking. At present, most of the docking racks are rail-type. This type of racking has high requirements on the factory site and guarantee conditions (rails), and most of the racking racks are heavy, complex in structure, and difficult to transfer, which lea...

Problems solved by technology

At present, most of the docking racks are rail-type. This type of racking has high requirements on the factory site and guarantee conditions (rails), and most of the racking racks are heavy, complex in structure, and difficult to transfer, which leads to the choice of the final assembly plant. Problems such as small scope and low assembly efficiency
