The utility model has the advantages that：The lifting of pantograph is driven using hydraulic driving mode, is caused by electricity
Bow, which is flowed and lifted, reaches excellent performance.Because liquid phase has Incoercibility for gas, therefore, when pantograph liter
Bend and contact after power network, hydraulic circuit is cut off by hydraulicdirectional control valve, just can be constituted in lift cylinder one it is closed can not
The liquid chamber of compression, and be unlikely to occur compressing the appearance for causing loose contact because of the influence of external condition.Further, since
The sealing property of hydraulic system is easy to observation, so being easy to ensure that the pressure of cylinder keeps constant, therefore can be cut off after rising bow
Motor also can the pressure of holding system is constant within considerable time, save the energy.Because hydraulic-driven is by motor belt motor
The hydraulic station of oil pump is moved to run, so there is small volume, the low characteristic of noise, be worthy to be popularized use, simultaneously because being equipped with
Hydraulic synchronization device, it is ensured that when mine car uses two pantograph equipment, pantograph can meet synchronization lifting.
