The invention discloses a diagnosis method and device for concrete equipment pipe blocking. The method comprises steps of acquiring an overpressure alarm signal sent by a pumping hydraulic system of concrete equipment; collecting a pumping control signal of the concrete equipment, detecting whether a self-dredging control signal appears in the pumping control signal after the pumping hydraulic system sends the overpressure alarm signal, if it is detected that the self-dredging control signal still acquires the overpressure alarm signal sent by the pumping hydraulic system of the concrete equipment in third time, determining that the concrete equipment pipe blocking occurs, wherein the self-dredging control signal comprises: sending a pumping stop signal after the pumping hydraulic system sends the overpressure alarm signal, then sending a reverse pumping signal and continuing for second time, and then sending an auto pumping starting signal. The method can rapidly determine whether pipe blocking occurs in the equipment through identification of the overpressure alarm signal, the pumping control signal and corresponding time, preventing improper operation from aggravating pipe blocking.
Description
technical field [0001] The invention relates to the diagnosis of concrete equipment, in particular to a method and device for diagnosing pipe plugging of concrete equipment. Background technique [0002] With the rapid development of the concrete industry, the lack of natural resources brought about by the continuous mining of concrete raw materials has led to the continuous development of substitutes for concrete raw materials. The application of machine-made aggregates, slag and other substitutes has continued to increase. The difficulty is getting bigger and bigger, and it is easy to block the pipe. Blockage will affect the customer experience and reduce the satisfaction of the equipment. The working condition adaptability of concrete pumping equipment needs to be improved urgently. [0003] The pumping system is the core of the whole concrete pumping equipment. Its performance is a key indicator to measure the performance of the whole machine. In the process of pumpin...
