AI Technical Summary

Technical Problem

The existing hydraulic outrigger system suffers from micro-leakage and slight recoil settlement under high load conditions, resulting in delayed feedback of the construction trolley chassis tilt, which affects the accuracy and safety of high-altitude splicing.

Method used

The composite leveling outrigger structure consists of an inner hydraulic cylinder, an outer guide sleeve, and a middle rotating nut sleeve. Combined with servo drive components and pressure sensors, it achieves active prediction and dynamic displacement compensation through a feedforward calculation algorithm, and eliminates settlement errors by using mechanical self-locking and hydraulic unloading mechanisms.

Benefits of technology

It achieves chassis attitude locking without delay under heavy load conditions, ensuring high-altitude splicing accuracy and safety, avoiding cumulative settlement errors caused by hydraulic micro-leakage, and improving assembly efficiency and safety.
