The invention relates to an automatic pedal device and system for filling gaps of a subway platform. The device comprises a rack arranged at the bottom of a shielding door in the length direction of the shielding door, a pedal and a pedal telescopic transmission assembly, wherein the pedal and the pedal telescopic transmission assembly are arranged below the platform. A pedal telescopic transmission assembly is provided with a gear, a steering gear, a coupler and a lead screw mechanism which are in transmission connection in sequence, the lead screw mechanism is provided with a rotatable ballscrew and a supporting base which is connected to the ball screw and can move front and back along with rotation of the ball screw, the gear is in meshed connection with the rack, and the supporting base is fixedly connected with the pedal. A pedal is used for driving the pedal to extend forwards out of the platform and retract backwards into the platform in the opening and closing process of theshielding door. Compared with the prior art, a power source does not need to be additionally arranged, opening and closing of the shielding door are ingeniously utilized, stretching and retracting ofthe pedal can be achieved through mechanical transmission, and the whole process is automatically conducted.

    本发明涉及一种用于填补地铁站台缝隙的自动踏板装置及系统,该装置包括沿屏蔽门长度方向设置于屏蔽门底部的齿条、以及设置于站台下方的踏板和踏板伸缩传动组件;踏板伸缩传动组件具有依次传动连接的齿轮、转向器、联轴器和丝杠机构,丝杠机构具有可转动的滚珠丝杠以及连接于滚珠丝杠上并可随滚珠丝杠转动而前后移动的支撑座,齿轮与齿条啮合连接,支撑座与踏板固定连接,用于在屏蔽门打开和关闭过程中带动踏板向前伸出站台和向后缩回站台。与现有技术相比,本发明无需额外设置动力源,巧妙地利用屏蔽门的开合,通过机械传动即可实现踏板的伸出和缩回,整个过程自动进行。
