Space rocket body rolling apparatus

Abstract

The invention relates to a space rocket body rolling apparatus, comprising: at least two traveling rolling mechanisms available for height adjusting and used for driving a rocket body to axially roll,wherein the traveling rolling mechanisms are arranged at the lower end of the rocket body, and at least one of the traveling rolling mechanisms is provided with a side adjusting mechanism for adjusting the axis of the rocket body; rolling rings cooperating with flanges of the rocket body and supported on the traveling rolling mechanisms; a control cabinet connected with the traveling rolling mechanisms and controlling at least one traveling rolling mechanism to operate. The problem that a traditional rocket body has uncontrollable rolling angle or cannot roll is solved; a motor with a band brake is used to control rollers to rotate or stop, rolling linear speed and angle of a barrel and a rocket body can be controlled precisely, and transmission is more stable; a single drive mode and a multi-drive mode can be freely switched according to the length and weight of the barrel; the space rocket body rolling apparatus is safe and reliable to use, simple and convenient to operate, low in time and manpower consumption, and high in automation level.

Description

technical field [0001] The invention relates to the technical field of aerospace rockets, in particular to a rolling device for a rocket body of an aerospace rocket. Background technique [0002] As we all know, the existing Long March 5 rocket has a diameter of 5.4 meters, and the Long March 7 rocket has a diameter of 3.7 meters. At present, when assembling the single-stage cylinder body and the rocket inner cavity of the rocket body at all levels and the assembled rocket body of the space rocket, two operation methods are generally adopted: 1. Ladders are connected in the cylinder body; 2. Manual alignment The barrel and rocket body roll through a certain angle. [0003] However, the former has a lot of work to build the ladder frame, and it is difficult to determine the focus point. The assembled device is used as the fixed point, which has a relatively large impact on product quality and has potential safety hazards; There are two rollers on the carriages at both ends ...

Problems solved by technology

[0003] However, the former has a lot of work to build the ladder frame, and it is difficult to determine the focus point. The assembled device is used as the fixed point, which has a relatively large impact on product quality and has potential safety hazards; There are two rollers on the carriages at both ends of the barrel, and rolling rings are installed at both ends of the barrel and the arrow body. The rollers on the carriage support the barrel and the arrow body by supporting the rolling rings, and they roll when they rotate. A rope is tied in the hole of the ring, and the rope is manually pulled to make the ring drive the cylinder to rotate. The rotation angle is uncontrollable. When the cylinder is light in weight, the inertia is large, the rotation angle is uncontrollable, and there are safety problems. Do not move
