The hydraulic system comprises an oil pump motor set, the oil pump motor set is communicated with a first one-way valve and an overflow valve through a second oil duct, and the overflow valve is communicated with a second reversing valve through a third oil duct. The first one-way valve is communicated with the second one-way valve and the first reversing valve through a fourth oil duct, the first reversing valve is communicated with the energy accumulator through a fifth oil duct, the second one-way valve is communicated with the second reversing valve through a sixth oil duct, and the second reversing valve is communicated with a rodless cavity of the oil cylinder through a seventh oil duct. And the second reversing valve is communicated with a rod cavity of the oil cylinder through an eighth oil duct. The hydraulic system is small in occupied area, can be arranged between parallel rails, is close to a brake mechanism linked with an oil cylinder, is convenient to control and maintain visually, is low in energy consumption and high in reliability, and can brake stably.
