AI Technical Summary
Existing rigid chains are prone to deflection accumulation and insufficient lateral stability under long-span horizontal cantilever conditions, affecting push-pull accuracy and stability.
A long-span cantilever horizontal rigid chain was designed, which adopts a telescopic sleeve structure. It provides stable support through the sliding cooperation of multiple telescopic cylinders with gradually decreasing size. The buffer structure and linear guide rail enhance the stability and accuracy of the rigid chain.
It effectively avoids the accumulation of deflection when a rigid chain is cantilevered over a long distance, improves the stability and lateral stability of the front end, and enhances the accuracy and safety of use in large-span environments.
