The highway pantograph lifting mechanism comprises an arm rod mounting seat, an arm rod, an electric push rod, an L-shaped adapter plate and a spring, the electric push rod is located above the arm rod, the arm rod mounting seat is rotationally connected with the arm rod, and the two ends of the spring are rotationally connected with the arm rod mounting seat and the arm rod respectively; one end of the electric push rod is rotationally connected with the arm rod mounting seat, and the other end of the electric push rod is connected with the arm rod through an L-shaped adapter plate. In a pantograph descending state, the electric push rod extends to the longest position, the front end of the L-shaped adapter plate is in contact with the arm rod, and the arm rod is fixed and cannot move; in the pantograph rising state, the electric push rod is shrunk to be the shortest, the front end of the L-shaped adapter plate and the arm rod are in a disengaged state, the arm rod is not fixed and can swing up and down to adapt to the height change of a contact net and the height change of a road surface, and the stability of pantograph-catenary contact force is guaranteed.
本发明公开了一种公路受电弓升降弓机构,包括臂杆安装座、臂杆、电推杆、L型转接板、弹簧,电推杆位于臂杆上方,臂杆安装座与臂杆转动连接,弹簧两端分别与臂杆安装座和臂杆转动连接;电推杆一端与臂杆安装座转动连接,电推杆的另一端通过L型转接板与臂杆连接。在降弓状态时,电推杆伸到最长,L型转接板前端与臂杆处于接触状态,臂杆被固定住不能运动;在升弓状态时,电推杆缩到最短,L型转接板前端与臂杆处于脱开状态,臂杆没被固定住,能上下摆动适应接触网高度的变化和路面的高度变化,保证了弓网接触力的稳定。
