Abstract

The invention relates to a rope traction robot, in particular to a rope traction robot applied to space material transportation and assembly. The problems that an existing space material transporting and assembling device is limited in transferring distance and low in transporting efficiency are solved. A supporting structure (1) is of a frame structure, the supporting structure (1) is arranged in a space weightless in the space, at least three points, not located on the same straight line, of the supporting structure (1) are each provided with a traction mechanism (3), one end of each traction rope (4) is connected with the corresponding traction mechanism (3), and the other end of each traction rope (4) is connected with a movable base (2) located in the middle of the supporting structure (1). The multiple traction ropes (4) drive the movable base (2) to move under the action of the traction mechanism (3), and the lower end face of the movable base (2) is provided with the robot through the lifting mechanism and the butt-joint clamping mechanism to achieve transportation and assembly of goods and materials. The invention is used for space material transportation and assembly.

Description

technical field [0001] The invention relates to a rope traction robot, in particular to a rope traction robot applied to the transportation and assembly of space materials. Background technique [0002] At present, almost all spacecraft are manufactured and verified on the ground, and then sent to a predetermined orbit by a launch vehicle. With the continuous improvement of space exploration requirements, the contradiction between the rapidly increasing size of spacecraft and the slowly increasing volume and weight of launch vehicle payloads has become increasingly prominent. Large-scale deployable mechanisms are an effective way to solve the above-mentioned contradictions, but the deployment caliber, weight and mechanical properties still cannot meet the development needs of large or ultra-large space structures in the future. Therefore, the construction concept based on "modular deployable mechanism + on-orbit assembly" has become a technical consensus in the design and c...
