The invention relates to the technical field of rail transit, in particular to an escape door movable pedal linkage mechanism and a working method.The escape door movable pedal linkage mechanism comprises a door frame, a door leaf, a movable pedal, a linkage assembly and a lap joint piece, and the door leaf can turn over relative to the door frame so that door opening and door closing can be achieved; the movable pedal can rotate relative to the door leaf; the linkage assembly comprises a first gear, a first rack meshed with the first gear, a second gear and a second rack meshed with the second gear, the first gear and the second gear are both rotationally connected to the door leaf, the first gear is in linkage with the door leaf, and the second gear is in linkage with the movable pedal; transmission connection or transmission disconnection between the movable pedal and the door leaf is achieved through the lap joint piece, so that the movable pedal and the door leaf are in incomplete synchronous transmission, the movable pedal can avoid the position of the connecting rod plate, and interference between the movable pedal and the connecting rod plate is avoided.
本发明涉及轨道交通技术领域,特别涉及一种逃生门活动踏板联动机构及工作方法,包括门框、门页、活动踏板、联动组件和搭接件,门页可相对门框翻转从而实现开门和关门;活动踏板可相对门页转动;联动组件包括第一齿轮、与第一齿轮啮合的第一齿条、第二齿轮和与第二齿轮啮合的第二齿条,第一齿轮和第二齿轮均转动连接在门页上,第一齿轮与门页联动,第二齿轮与活动踏板联动;第一齿条和第二齿条通过搭接件传动连接或者传动脱开,本发明通过搭接件实现活动踏板与门页的传动连接或传动脱开,使得活动踏板与门页不完全同步传动,从而使得活动踏板能够避开连杆板位置,避免两者干涉。
