Research on the design of subway interval protective airtight partition door overturning mechanism
The protective airtight partition doors of subway intervals are set on the main line track,which is a spe-cial and complicated working condition with great technical difficulties.This paper proposed the combination of large and small doors into a complete partition door by the flip mechanism,without the need to hang other partition devices on the top of the doorway or other positions,which is of great significance to ensure the safety of subway op-eration in normal times.Through the crank-slider mechanism,coupling,manual mechanism design calculations and simulation analysis of the flip mechanism,reasonable parameters of the flip mechanism were determined,sol-ving the major problem of opening and closing the door under the condition of non-opening of the confluence,and laying the foundation for the successful development of the LQGDFM(A)3846(6)-type subway inter-district pro-tective airtight partition door.
