HVDC Sub-Module Replacement Base With Guide Rail Alignment

The patent introduces a replacement base as an intermediary device between the sub-module and the aerial ladder truck. This replacement base provides a stable platform that distributes the weight of the sub-module, preventing sudden center of gravity changes in the aerial ladder truck while enabling safe maintenance operations.

The replacement base acts as a counterweight system by providing a stable foundation that compensates for the weight of the sub-module. The base structure with its support legs and connection to the ground creates a counterbalancing effect that prevents the aerial ladder truck from becoming unstable when handling heavy sub-modules.

The replacement base serves as a mediator between the worker and the heavy sub-module. It provides mechanical advantage through its structure and connection points, allowing workers to safely handle and position the sub-module without direct manual lifting, thereby reducing physical strain and safety risks.

The replacement base is designed to enable the sub-module to essentially service itself during maintenance. The base provides the necessary support and positioning mechanisms, allowing the sub-module to be easily detached, moved, and reattached with minimal manual intervention, reducing worker exposure to dangerous conditions.

The replacement base incorporates preliminary alignment features such as guide rails and positioning mechanisms that automatically align the sub-module with the fixing rails before final attachment. This preliminary action ensures proper alignment is achieved before the secure attachment process begins, eliminating the trade-off between stability and alignment difficulty.

The patent replaces manual alignment operations with mechanical guidance systems. The guide rails and positioning mechanisms provide automatic mechanical alignment, substituting for difficult manual positioning operations and ensuring both accurate alignment and secure attachment simultaneously.
