The invention discloses a cableway hydraulic driving
system with speed adjusted by an energy accumulator. The cableway hydraulic driving
system consists of an
electric machine, a variable-capacity
oil pump, a motor and a hydraulic driving
system, wherein the
electric machine is connected with the variable-capacity
oil pump; high-pressure oil ports A and B of the variable-capacity
oil pump are connected with oil ports A and B of the motor; a hydraulic speed adjusting system comprises the variable-capacity oil pump; a filling pump opening PS in the variable-capacity oil pump is connected with a filter; the filter is connected with a throttling orifice of a pressure limiting valve
bank; the throttling orifice of the pressure limiting valve
bank communicates with the pressure limiting valve
bank and a port P of a solenoid
directional valve respectively; an oil return port of the pressure limiting valve bank, a port T of the solenoid
directional valve and a
pilot control port X2 of the variable-capacity oil pump are connected with an
oil tank T; a port B of the solenoid
directional valve is connected with the energy accumulator and a
pilot control port X1 of the variable-capacity oil pump respectively through throttling orifices of the solenoid directional valve; and an oil inlet T1 and an oil outlet T2 of the variable-capacity oil pump communicate with the
oil tank T. The cableway hydraulic driving system has the beneficial effects that the system is simple to control and is stable and reliable; the number of control valve banks and matched
electrical control are reduced, costs are saved, and
fault rate is reduced; and safety protection is complete.
