The invention discloses an intelligent hydraulic system for a self-moving machine tail and a control method. The hydraulic system comprises an oil tank, an oil suction filter, a motor, a variable pump, an execution unit, a walking unit, a control module, a cooler and an oil return filter, wherein the execution unit comprises an overflow valve I, an energy accumulator, a multi-way valve I, oil cylinder sets and pressure sensors, the walking unit comprises a multi-way valve II, a left walking motor and a right walking motor, the multi-way valve I comprises an end plate I, a reversing valve I and a tail plate I, and the multi-way valve II comprises an end plate II, a reversing valve II and a tail plate II. By means of the intelligent hydraulic system for the self-moving machine tail and the control method, three working modes including an action mode, a walking mode and a mixing mode are provided for operation of the self-moving machine tail hydraulic system, the control module can select different working modes according to specific working conditions, automatic feeding, moving, belt deviation adjusting and hydraulic energy recycling of the self-moving machine tail are achieved, intelligent control of the self-moving machine tail can be achieved, the labor intensity of workers is reduced, the tunneling efficiency is improved, and efficient and rapid tunneling of coal roadways is achieved.
Description
technical field [0001] The invention relates to the technical field of coal mining machinery, in particular to an intelligent hydraulic system and a control method for the tail of a self-moving machine. Background technique [0002] The self-moving tail is a mobile device for fully mechanized excavation in coal mines, and it is mainly used in conjunction with belt conveyors and loaders. The intelligent hydraulic system and control method for the self-moving tail can realize the automation of functions such as feeding, walking, and belt deviation adjustment of the self-moving tail. The daily working hours of the self-moving machine tail on the excavation face are short. If the pump station works for a long time, more overflow will be generated, and the heat generated by the system will increase, resulting in increased cooling energy consumption of the system. [0003] The Chinese patent of CN103144924A discloses a hydraulic self-moving tail device, which realizes its own mov...
