A ground rail 2 is installed within the foundation pit 1, serving as a basic support and guide structure. A displacement slide 3 is slidably mounted on the ground rail 2, moving along the X-axis. The displacement slide 3 acts as a moving component, moving along the X-axis above the ground rail 2. Both the ground rail 2 and the displacement slide 3 are made of high-strength castings and precision-machined to ensure structural strength and stability. A zero-point locator 31 is installed on the displacement slide 3, connecting it to a moving unit. The connection point above the displacement slide 3 uses a zero-point locator as a quick-positioning and locking mechanism.

In this configuration, all matching moving units can be connected and fixed. The displacement slide 3, as a transition component, can be equipped with different moving units as needed, such as a corner moving unit 4, a lifting moving unit 5, a universal column 6, and a three-axis universal column 7. A disassembly column ground storage platform 8 is provided in the pit 1. The specific configuration of the moving units is selected according to the actual assembly situation. Limit switches and limit blocks can be set at both ends of each moving unit in each moving direction, which controls and improves the safety of the system in terms of structure. If the moving unit needs to be disassembled, it can be connected and fixed to the disassembly column ground storage platform 8 after being disconnected from the displacement slide 3. The pit 1 is equipped with a motor cabinet 9 for controlling the displacement slide 3 and the moving units, and an integrated control console 10. Example
