Problems solved by technology

[0003] However, the hydraulic system is very prone to heat generation during high-pressure work and consumes a lot of energy. Therefore, the high-power powered cable laying technology widely used in the cable laying process currently produces a large energy loss.
However, the energy-saving measures of the hydraulic system in the prior art are generally to control the displacement of the main pump by detecting the pressure of the driving oil circuit, or to control the displacement of the main pump by the action of the sequence valve. When the main pump is controlled, some hydraulic pressure Components are extremely fragile and prone to accidents

Abstract

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.

Description

technical field [0001] The invention relates to a hydraulic energy-saving control system, in particular to a hydraulic energy-saving control system for cable unwinding and unwinding. Background technique [0002] In large-scale engineering construction, in order to transmit and supply power to mobile operation equipment, it is often necessary to transport and retract cables. The cable reeling vehicle is the necessary special equipment to complete the transportation, laying, retracting and storage of the cables on site. During the operation, it mainly drives the motor to drive the reel to rotate through the hydraulic system to realize the cable retraction. [0003] However, the hydraulic system is very prone to heat generation during high-pressure work and consumes a lot of energy. Therefore, the high-power powered cable laying technology widely used in the cable laying process at present produces a large energy loss. However, the energy-saving measures of the hydraulic syst...
