Detachable rolling ring device for large rocket heavy load

Abstract

The invention relates to a detachable rolling ring device for large rocket heavy load. The detachable rolling ring device comprises a rear rolling ring, a chassis with fixed and movable dual-purpose wheels, rear rolling ring large-section support and brackets, rear rolling ring small-section brackets and a rear rolling ring large-section support, wherein the rear rolling ring large-section supportand brackets and the rear rolling ring small-section brackets are sequentially arranged on the rear side of the chassis in the front-rear direction, and the rear rolling ring large-section support and brackets and the rear rolling ring small-section brackets have an up-and-down adjusting function; the rear rolling ring large-section support is arranged on the rear rolling ring large-section support and brackets; and the rear rolling ring is composed of a rear rolling ring large-section arranged on the rear rolling ring large-section support and a rear rolling ring small-section arranged on the rear rolling ring small-section brackets. According to the detachable rolling ring device, the rear rolling ring is designed into the detachable structure formed by assembling the rear rolling ringlarge-section and the rear rolling ring small-section, and an auxiliary disassembling and assembling trolley for assisting in the switching between an auxiliary rear rolling ring small-section supportand the rear rolling ring large-section support is designed, so that when the rear rolling ring is assembled with a rocket body, the rear rolling ring is prevented from colliding with a protrusion drawing cover on the rocket body; and moreover, the rear rolling ring can be quickly disassembled and assembled.

Description

technical field [0001] The invention relates to the technical field of aerospace rockets, in particular to a heavy-duty detachable rolling ring device for a large rocket. Background technique [0002] Usually, after the final assembly of the large rocket is completed, in order to inspect the rocket debugging process during the final assembly and debugging stage of the large rocket, it is necessary to roll the rocket body and turn the points that need to be checked to a position that the operator can reach to facilitate the operation. The existing rocket roll is to use an electric rolling carriage at both ends of the rocket to drive the roll ring to rotate, and the roll ring is connected with the rocket body to drive the rocket body to roll. [0003] After the final assembly of the big rocket is completed, the underside of the rear transition section is equipped with a protrusion detachment cover, and the binding support of the rear transition section is located inside the pr...

AI Technical Summary

Problems solved by technology

Therefore, there is an urgent need to design a detachable rear rolling ring in order to avoid protrusions from being pulled out of the cover, and solve the problem that the rear rolling ring is difficult to connect with the rear transition section binding support

In addition, there is a lack of auxiliary devices used in conjunction with the detachable rear roller ring in the existing market, so that the rear roller ring can be disassembled and switched
