The invention discloses a double-power hydraulic system. The double-power hydraulic system comprises an oil tank, two hydraulic systems, two electromagnetic reversing valves and two brake hydraulic cylinders, and is characterized in that an air filter is arranged on the oil tank; each hydraulic system mainly includes an oil sucking filter, a hydraulic pump and a pipeline finish oil filter driven by a motor, and an overflow valve; the oil sucking filter is positioned between the oil tank and the hydraulic pump; the pipeline finish oil filter and the overflow valve are arranged at the upper part of the hydraulic pump in sequence; an outlet of the overflow valve extends into the oil tank through an oil pipe; a high-pressure ball valve is arranged in an outlet of the a high-pressure oil pipe of each hydraulic system, and is connected with a third high-pressure oil pipe; two ends of the third high-pressure oil pipe are respectively connected with two electromagnetic reversing valves and two brake hydraulic cylinders; and a pressure gauge is arranged on the third high-pressure oil pipe. The double-power hydraulic system has such characteristics as simple structure, fast pressure relief, reliable performance and control of two brake devices by one-use and one-standby hydraulic systems.
Description
technical field [0001] The invention belongs to the field of hydraulic technology, and in particular relates to a dual-power hydraulic system. Background technique [0002] In terms of braking power sources, various methods such as hydraulic, pneumatic, mechanical, and electromagnetic methods are adopted. With the continuous development of the braking industry, hydraulic systems are gradually favored as the power source of the braking device. It is characterized by simple structure, Large braking force, safe and reliable, one-use and one-standby hydraulic system, etc. When hydraulic components fail, they cannot be quickly repaired or replaced, affecting normal production tasks. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides the characteristics of simple structure, fast pressure release, reliable performance, one hydraulic system for use and one backup for controlling two braking devices, and the like....
