Hydraulic system for steel collection device

Abstract

The invention discloses a hydraulic system for a steel collection device, which comprises a hydraulic station, an energy accumulator set, a first control valve stand, a second control valve stand, a third control valve stand and a fourth control valve stand, wherein the first, second, third and fourth control valve stands are connected with the hydraulic station; the hydraulic station mainly consists of a plunger pump unit and an oil tank assembly; the plunger pump unit is connected with the oil tank assembly through a pressure regulating valve bank; the energy accumulator set is connected on the oil tank assembly; the first control valve stand is formed by a cold bed lifting loop, a baffle lifting loop and a shear blade replacing loop; the second control valve stand is formed by a baffle lifting loop, a horizontal supporting steel moving machine loop and a short ruler collection lifting chain loop; and both the third control valve stand and the fourth control valve stand are respectively formed by a baffle lifting loop, a tightening machine loop and a collection lifting chain loop. The hydraulic system for the steel collection device has the characteristics that the hydraulic system operates stably and has high control precision; the fault rate is reduced; and the liquid level, the liquid temperature, the pressure and the speed are all controlled by adopting a PLC (Programmable Logic Controller), so that the influence of human factors is eliminated, energy is saved, the production efficiency is improved, the product quality is strengthened and the production automation is completely implemented.
