Integrated large-angle rolling and posture adjusting rack car

Abstract

The invention provides an integrated large-angle rolling and posture adjusting rack car. The rack car comprises two parallel guide rails and two movable frames transversely erected on the guide rails. The movable frames can move along the guide rails through the rack car. Each movable frame comprises a rolling bracket and a butt joint bracket, the butt joint bracket is located on the side where the two movable frames are close to each other, and the rolling bracket is located on the side where the two movable frames are far from each other. The rack car further comprises a detachable rolling ring capable of rolling on the rolling bracket, the detachable rolling ring can be formed by connecting a plurality of equally-divided rings with the ends provided with connecting end faces and threaded holes, and the side faces of the equally-divided rings are provided with connecting holes. The integrated large-angle rolling and posture adjusting rack car integrates rocket part section large-angle rolling and part section posture adjusting, rocket part section assembling and part section posture adjusting are carried out on the same station, and the defects that due to repeated hoisting, total assembling efficiency is low and the safety performance is poor are overcome.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, and in particular relates to a large-angle rolling and attitude-adjusting integrated frame vehicle. Background technique [0002] At present, the launch vehicle assembly process is mainly divided into two processes: section assembly and section attitude adjustment. Section assembly is to assemble the necessary components (including sensors, brackets, etc.) required inside and outside each section. Since the supportable part of the rocket body and the wrapping angle have certain values, it is necessary to perform a large-angle rolling operation on the rocket body during the assembly process to complete the assembly of the components inside the entire rocket body. The process is carried out on a rolling frame car. During the rolling process of the rocket section, in order to achieve the purpose of protecting the rocket body, the rocket section is not allowed to directly contact the carriage brac...

AI Technical Summary

Problems solved by technology

[0004] The operation sequence of the above two processes is: first assemble the upper part of the rolling frame car, and then adjust the section to the docking frame car to start the attitude adjustment work after the assembly is completed; but in the actual assembly process, due to many parts, it is inevitable There will be a phenomenon that the two processes will be reworked back and forth, resulting in the need for multiple hoisting, which greatly reduces the efficiency of assembly, and the operation is complicated and the safety factor is low
