Operation construction method of main-line turnout stabilizing carriage

An operation construction method of a main-line turnout stabilizing carriage comprises the step that a main-line turnout zone is divided into five stages, namely the stage I of normal main-line operation before turnout, the stage II of single-side rail clamping of a trip switch part, the stage III of normal main-line operation of a connection part, the stage VI of single-side rail clamping of a frog part, and the stage V of normal main-line operation after a train drives out of the turnout zone. The operation construction method researches the stable operation procedure and the construction mode of the main-line turnout stabilizing carriage in the main line and the turnout zone. A folding and unfolding stabilizing device is used in a main-line section, stabilizing operation of the main line and the turnout zone can be conducted continuously without being stopped by switching operation modes, and time is saved. Meanwhile, turnout operation has the specificity different from main line operation.
