A hydraulic energy-saving
control system of a cable reeling and unreeling vehicle comprises an
oil tank, a load-sensitive
system, couplers, an electromotor, oil supplementing switch valve valves, a displayer with the touch
input function, a controller, a multi-circle
encoder, a coiling block, a motor, a balance valve
assembly and a multi-path valve
assembly. The electromotor and the load-sensitive
system are connected through one coupler. The load-sensitive
system and the multi-path valve
assembly are connected through a hydraulic oil
pipe. The multi-path valve assembly and the balance valve assembly are connected through a hydraulic oil
pipe. The balance valve assembly and the motor are connected through a hydraulic oil
pipe. The motor is connected with the coiling block through the other coupler. The controller is connected with the multi-circle
encoder, the displayer with the touch
input function, the balance valve assembly and the multi-path valve assembly through a circuit. The load-sensitive system, the multi-path valve assembly and the
oil tank are communicated through a hydraulic oil pipe. The load-sensitive system is communicated with the balance valve assembly through a hydraulic oil pipe, the oil supplementing switch valves are installed on the oil pipes. The hydraulic energy-saving
control system has the advantages of being reliable in work, diverse in function, high in responding speed, capable of reducing consumption and saving energy and the like.
