The invention discloses a turnover type pedal device for a rail train. The turnover type pedal device comprises a first-stage pedal, a second-stage pedal, a driving device, a swing rod assembly and a pedal seat assembly, wherein the driving device, the swing rod assembly and the pedal seat assembly are sequentially connected; the driving device drives the swing rod assembly to do linear motion, the swing rod assembly and the rotating support coaxially and synchronously rotate, the first-stage pedal is driven to do overturning motion, and limiting is conducted through the limiting device. The second-stage pedal is connected with the pedal connecting rod and the connecting plates on the two sides, rotates with the first-stage pedal as a base and is limited through the limiting pins on the two sides. The first-stage pedal is pushed by the air cylinder to achieve overturning and withdrawing actions, and the second-stage pedal is manually overturned and withdrawn through limiting pins on the two sides of the second-stage pedal; the secondary pedals form a spatial four-connecting-rod mechanism, interference after the device is retracted is avoided, the space is fully utilized, and connecting plates on the two sides are arranged in a scattered mode, so that the device has better movement stability and bearing rigidity.
本发明公开了一种用于轨道列车的翻转式踏板装置,包括一级踏板、二级踏板、以及依次连接的驱动装置、摆杆组件与踏板座组件;所述驱动装置带动摆杆组件做直线运动,摆杆组件与转动支架同轴同步转动,带动一级踏板做翻转运动,并通过限位装置进行限位;所述二级踏板与踏板连接杆、两侧连接板连接,二级踏板以一级踏板为底座进行转动,并通过两侧限位销进行限位。本发明一级踏板采用气缸推动实现翻转与收回动作,二级踏板采用人工及两侧限位销实现翻转与收回动作;二级踏板组成空间四连杆机构,避免了装置收回后的干涉,充分利用空间,并且两侧连接板分散布置,使装置有更好的运动平稳性和承载刚性。
