Introduces a novel lifting mechanism for climbing robots that improves vertical mobility using gear and link transmission, suggesting new applications in difficult environments.
A symmetrical telescopic arm lifting mechanism based on gear and link transmission is introduced. The input end motor drives the lower link group to rotate, and through the meshing reversal of the intermediate gear group, the upper link group is driven to rotate in the opposite direction, ultimately achieving a single degree of freedom in vertical lifting and lowering of the end load position. This provides a new idea for the design of climbing mechanisms for climbing robots, which can be applied to vertical climbing scenarios such as transmission line towers, gas pipelines, street lamp poles, etc. This paper mainly introduces the transmission principle, mechanical analysis, and dynamic simulation of this lifting mechanism.
