The invention discloses an electric lifting pedal for a rail locomotive, and belongs to the technical field of rail locomotives, the electric lifting pedal comprises a pedal frame, a lifting assembly and a pedal assembly, and the two sides of the pedal frame are each fixedly connected with a guide rod. The lifting assembly comprises a moving cross beam, a motor, a trapezoidal screw rod, a precise planetary steering gear and a movable copper sleeve, the two ends of the moving cross beam are slidably connected with the corresponding guide rods respectively, and an output shaft of the motor is in transmission connection with one end of the trapezoidal screw rod through the precise planetary steering gear. The pedal assembly is fixedly connected with the moving beam. Different heights of the electric lifting pedal can be freely adjusted through transmission of the motor and the trapezoidal lead screw, different foot rest height requirements of drivers and passengers are met, and the comfort of the drivers and the passengers is improved. The trapezoidal screw rod has a self-locking function, and the trapezoidal screw rod and the movable copper sleeve can be automatically locked after the motor loses power, so that the movable cross beam is locked.

    本发明公开了一种轨道机车用电动升降脚踏,属于轨道机车技术领域,包括脚踏框架、升降组件以及踏板组件,脚踏框架的两侧各固定连接有一个导杆。升降组件包括运动横梁、电机、梯形丝杆、精密行星转向器以及活动铜套,运动横梁的两端分别与对应导杆滑动连接,电机的输出轴与梯形丝杆的一端之间通过精密行星转向器传动连接。踏板组件与运动横梁固定连接。电动升降脚踏能够通过电机和梯形丝杆的传动实现不同高度自由调整,满足司乘人员不同的搁脚高度需求,提高司乘人员舒适感。梯形丝杆拥有自锁功能,电机失电后可自动将梯形丝杆与活动铜套锁定,从而使运动横梁锁定。
