The pedal turning plate structure comprises surrounding plates, turning plates, a panel, a transmission shaft, a swing hook and a tension spring which are symmetrically arranged, the tops of the two surrounding plates are rotationally connected with the turning plates, the other ends of the turning plates are fixedly provided with the panel, and one side of the periphery of the swing hook is fixedly connected with an inclined scraping plate; the two ends of the tension spring are hinged to the mounting holes formed in one side of the sliding plate and one side of the angle iron correspondingly, so that the tension spring is convenient to disassemble, the I-shaped sliding plate drives the end of the tension spring to slide in the movable groove by rotating the screwing block at the end of the screw, the initial length of the tension spring is limited, the tension spring is convenient to correct, and the working efficiency is improved. The limiting initial length of the tension spring in the pedal turning plate is independently adjusted, the service life of the tension spring is prolonged, and the situation that due to high-frequency turning of the turning plate, the tension spring cannot be corrected and needs to be replaced after deformation, and the cost of parts is increased is avoided.

    本发明公开了一种轨道车辆上下车用脚蹬翻板结构,包括对称设置的围板、翻板、面板、传动轴、摆动钩、拉簧,两个所述围板顶部转动连接有翻板,所述翻板另一端固定安装有面板,所述摆动钩外围一侧固定连接有倾斜的刮板;本发明通过拉簧两端分别铰接于滑板一侧与角铁一侧开设的安装孔中,从而实现了拉簧拆卸的便捷,通过转动螺杆端部的拧块,使得工字形滑板带动拉簧端部在活动槽中滑动,从而对拉簧初始长度限位,便于对拉簧进行校正,实现了对该脚蹬翻板中的拉簧单独调整限位初始长度,提高拉簧使用周期,避免翻板高频次翻转,使得拉簧变形后,无法校正,需要更换,增加了零部件成本。
