Standard knot assembling and disassembling system and operation method

The invention belongs to the technical field of engineering machinery, and discloses a system and an operation method for introducing standard knots by using an introduction trolley, lifting the standard knots by using a lifting mechanism, and completing equipment standard knot adding by using one-time large-stroke lifting. The device is simple in structure, safe and efficient, and the hook pulley block is simple in structure; 2, the hook construction mode is simple; one standard knot is lifted at a time through a steel wire rope pulley mechanism, step changing is avoided, and the knot adding construction efficiency is high; fourthly, the introduction trolley can be used as an introduction device as well as a basic section, and the structural part has multiple functions; 5, a large guide distance is formed between the guide pieces, so that the pressure of the guide pieces on the main chord members caused by the moment of the upper structure of the system can be reduced; sixthly, the stock system is good in de
