Zusammenfassung: | The utility model relates to a stop-running monitoring device of an oil pumping machine for monitoring running of the oil pumping machine in the field of oil field exploitation. The stop-running monitoring device of the oil pumping machine is characterized by consisting of an infrared reflection sensor, a drive circuit, a monostable trigger circuit, a monitoring circuit and an alarm horn. The infrared reflection sensor D is installed on a beam hanger, the drive circuit is connected with a resistor R3 and a triode BG2 and then connected with an integrated circuit IC, the monostable trigger circuit is connected with a triode BG1 after being connected with a capacitor CI and a capacitor C2 through the integrated circuit IC, the monitoring circuit is formed by connecting the infrared reflection sensor with a resistor R1, a resistor R2 and the triode BG1, and the alarm horn L is connected with a power supply DC and a switch K. The stop-running monitoring device of the oil pumping machine achieves alarm by detectin |
