Abstract

The present invention provides a segment component installation tool and installation method for installing and debugging C and I components, comprising a base, a segment simulation frame, a crawling frame, and an installation mechanism; the segment simulation frame comprises a segment support frame, a segment frame, and an identification seat; the crawling frame comprises a base, a vibration assembly, and a crawling track; the installation mechanism comprises a crawling unit, an installation unit, and a guide unit; the crawling unit comprises a crawling support and a gear movably connected to the crawling support; the installation unit is movably connected to both the crawling support and the guide unit; the guide unit comprises a guide body and first, second, and third guide members disposed on the guide body. The present invention simulates the vibration working state of the component installation mechanism by providing a crawling frame excitation structure, and simultaneously uses a control unit to control the operation of the equipment and store operation information. This allows for convenient and effective testing of the performance of the installation mechanism, preemptively exposing and avoiding design defects of the mechanism, and reducing the overall machine development cost.
