Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the technical field of aerospace engine production, and in particular to an intelligent heavy-load fork-type omnidirectional mobile attitude adjustment platform. Background Art
[0002] Aerospace engines are placed vertically on pallets and transported from designated locations to various workstations for docking and inspection. This requires frequent transfers, precise positioning, and fine-tuning of the engine's position. In a vertical position, the engine occupies a relatively small area. While heavy-duty forklifts or cranes can lift and transport the engine, they cannot automatically drive to the designated workstation, accurately position it, or fine-tune its position. Furthermore, heavy-duty forklifts lack omnidirectional mobility and have a large turning radius, requiring a large space. Currently, this work requires the coordination of multiple personnel, making it difficult to position and adjust the engine's position once it reaches the workstation. Smart factory workshops often require fully automated, unmanned operations, meaning no personnel are present in the workshop; instead, control is maintained from a control room via computers and video monitors. Military enterprises often require that wireless communication be prohibited for signal transmission. Given these current conditions and needs, a smart, heavy-duty, forklift-mounted, omnidirectional mobile position adjustment platform is needed. Summary of the Invention
[0003] The present invention aims to provide an intelligent, heavy-duty, fork-mounted, omnidirectional mobile attitude adjustment platform that addresses the aforementioned challenges. This platform integrates automated transport and attitude adjustment, automatically navigating and omnidirectionally transporting the engine to a designated workstation. After docking or testing, the engine is automatically transported to the next workstation, ensuring accurate transport and positioning of aerospace engines during production and improving transport efficiency.

[0061] The beneficial effects of the embodiments of the present invention are as follows: the present invention discloses an intelligent heavy-duty fork-type omnidirectional mobile attitude adjustment platform.
