Abstract

The invention discloses a winch traction hydraulic control system, and belongs to the technical field of hydraulic control systems. According to the system, the input end of a main pump communicates with an oil tank. An electro-hydraulic proportional directional valve has the C-type function. A port P of the electro-hydraulic proportional directional valve communicates with the output end of the main pump, and a port T of the electro-hydraulic proportional directional valve communicates with the oil tank. A port A of the electro-hydraulic proportional directional valve communicates with a forward oil port of a hydraulic motor, and a port B of the electro-hydraulic proportional directional valve communicates with a reverse oil port of the hydraulic motor. An oil inlet of a hydraulic control one-way valve communicates with the output end of the main pump, and an oil outlet of the hydraulic control one-way valve communicates with an energy accumulator. A control oil circuit of the hydraulic control one-way valve communicates with the forward oil port of the hydraulic motor. An oil inlet of a one-way valve communicates with the reverse oil port of the hydraulic motor, and an oil outlet of the one-way valve communicates with the energy accumulator. By means of the winch traction hydraulic control system, high-speed traction, fast acceleration, fast deceleration and energy recovery of the hydraulic motor and a test vehicle can be achieved, and the test vehicle can make traction back-and-forth movement with relatively-small pump station power.

Description

technical field [0001] The invention relates to the technical field of hydraulic control systems, in particular to a traction winch hydraulic control system. Background technique [0002] In land, water and underwater reciprocating motion tests, it is usually necessary to configure winch traction equipment. [0003] The hydraulic control system used in the existing drawworks traction equipment usually includes a pump station and a three-position four-way electromagnetic reversing valve. The four-way electromagnetic reversing valve controls the forward or reverse rotation of the hydraulic motor. Since the output shaft of the hydraulic motor is connected to the drum drive of the winch, the forward or reverse rotation of the hydraulic motor can drive the winch to rotate, thereby realizing the winch's cable take-up or The cable release action drives the test vehicle to move back and forth. [0004] In the process of realizing the present invention, the inventor finds that ther...
