Detailed Description
The following description of the embodiments of the present invention, with reference to the accompanying drawings, will be made in further detail to explain, by way of example, the shape and structure of the components, the mutual positions and connections between the components, the functions and operating principles of the components, the manufacturing process, and the operation and use method of the components, so as to help those skilled in the art to more completely, accurately and deeply understand the inventive concept and technical solutions of the present invention.
The mining combined switch control actuating mechanism device shown in fig. 1 comprises an editable logic controller serving as a control core and a working mode selection unit of the editable logic controller, wherein a signal output pin of the editable logic controller is connected with a signal input end of the working mode selection unit, the working mode selection unit is connected with a signal input pin of the editable logic controller, the signal output pin of the editable logic controller is provided with an intermediate relay unit for connection, the signal output pin of the editable logic controller is provided with a detection unit for connection, the signal input pin of the editable logic controller is additionally provided with a signal output pin of an operating state display unit for connection, and the detection unit can perform bidirectional information communication with the operating state display unit.
The operation mode selection unit is a5, the a5 includes DI0, DI1, DI2 and DI3, the DIO, DI1, DI2 and DI3 are connected with the signal input pin of the editable logic controller by sequentially setting a relay normally-open point KX1, a relay normally-open point KX2, a relay normally-open point KX3, a relay normally-open point KX4, a contactor normally-open point KM11, a contactor normally-open point KM22, a contactor normally-open point KM33 and a contactor normally-open point KM44, and the DIO, DI1, DI2 and DI3 are connected with the signal input pin of the editable logic controller by additionally setting a one-loop current automatic switching control point KC1 and a three-loop automatic switching control point KC 2.
In the power supply line with alternating current of 50Hz and 1140V or 660V, a programmable logic controller is adopted to realize various control functions of the switch. The selection of different working modes is used for realizing 8 different working modes such as single control, joint control, sequential control, single-machine double-speed manual switching, single-machine double-speed automatic switching, double-machine double-speed manual switching, double-machine double-speed automatic switching and the like among multiple loops. The relationship between the control circuit and the detection and display unit of the editable logic controller is shown in fig. 1, DI0, DI1, DI2 and DI3 constitute an operation mode selection unit, and 8 different operation modes of multiple loops are realized by changing the on or off states of DIO, DI1, DI2 and DI 3. KF1, KF2, KF3 and KF4 are the normal open points in the integrated protector. If the system does not have abnormal conditions such as overload, short circuit, phase failure, electric leakage and the like, KF1, KF2, KF3 and KF4 are closed, and if not, the system is opened. KX1, KX2, KX3 and KX4 are relay normally open points, when a loop starting button is pressed, the relay KX1 is electrified, and a KX1 normally open point is closed. The signal is fed back to the editable logic controller via KX 1. The editable logic controller outputs signals through operation processing to connect the intermediate relay KA1, so that the contact of the editable logic controller acts to drive the contactor KM 1. KM11, KM22, KM33 and KM44 are contactor normally open points, and if a primary circuit contactor KM11 is attracted, the normally open point KM11 is closed. This completes the entire process of the programmable logic controller controlling the load loop. The other three-circuit contactors work in the same way. KC1 is the control point for automatic switching of the first and second loop currents. When a loop motor reaches a preset speed, KC1 is closed, and the information is sent to the output port of the editable logic controller. The editable logic controller realizes the operation of two loops after processing, and the shutdown of one loop completes the automatic current switching of the first loop and the second loop. KC3 is a three-and four-loop automatic switching control point.
The intermediate relay unit consists of an intermediate relay KA1, an intermediate relay KA2, an intermediate relay KA3 and an intermediate relay KA4, wherein the intermediate relay KA1, the intermediate relay KA2, the intermediate relay KA3 and the intermediate relay KA4 are respectively connected with a signal output pin of the editable logic controller.
The operation state display unit is A2, the A2 comprises D00, D01, D02 and D03, the D00, D01, D02 and D03 are respectively connected with the signal input pins of the editable logic controller, and the other fourth pin and the sixth pin of the A2 are respectively communicated with the first pin and the second pin of the detection unit.
The detection unit shown in fig. 2 is a6, the a6 includes a first pin, a second pin, a third pin, a fourth pin, a fifth pin, a sixth pin and a seventh pin, the first pin is a high level and is connected with the fourth pin of the operation state display unit, the second pin is connected with the sixth pin of the operation state display unit, a relay K1 is arranged between the first pin and the second pin, the third pin is grounded, the fourth pin is connected with a 5V power supply, a relay K2 is arranged between the fifth pin and the sixth pin, the seventh pin is an output point of the programmable logic controller,
the detection unit A6 is connected in series with a resistor R2, a resistor R3, a resistor R4 and a triode, and the A6 is additionally provided with a diode D1 for voltage stabilization and a capacitor C1 for filtering which are respectively connected in parallel.
A2 indicates a editable logic controller normal or fault state. The on and off of the DIO, the DI1, the DI2 and the DI3 are correspondingly indicated by four lamps, and the lamps are lightened to indicate the connection. The method is used for detecting whether the result processed by the editable logic controller is consistent with the preset working state. Meanwhile, the green light can be lightened when the logic controller operates normally; the red light lights up when an error occurs with the editable logic controller. And prompting the staff to find and process the fault in time. Therefore, a set of fault alarm system can be designed to find out faults and solve problems in time, and accidents are avoided. The operating principle of a6 is as shown in fig. 2, the first pin input is always high; the third pin is grounded; the fourth pin is connected with a 5V power supply; the seventh pin is the editable logic controller output point. When the editable logic controller works normally, the seventh pin is at a high level, otherwise, the seventh pin is at a low level. The specific detection process comprises the following steps: when the editable logic controller is in a normal operation state, the seventh pin is at a high level, and the first pin inputs the high level. After being stabilized by D1, the potential of the point Q controlled by R2, R3 and R4 after C2 filtering is also high. The triode is in saturation conduction, and the collector of the triode is at a low level. Relays K1, K2 get powered. The normally open point K2 between the fifth pin and the sixth pin is closed. The external power supply of No. 10 and No. 11 leads KA1, KA2, KA3 and KA4 to be electrified through K2 and an output port of an editable logic controller, and the reliable action of controlling the load contact is completed. If the editable logic controller is in the fault state, the output of the editable logic controller is in a low level, that is, the seventh pin is in a low level. The first pin inputs high level, although the Q point is still high level after voltage stabilization and filtering, the Q point can be discharged through the seventh pin, and the triode is cut off. The collector is at high potential, and Kl and K2 are in power-off state. The normally open point of K2 can not be closed, and KA1, KA2, KA3 and KA4 can not be powered. At this time, the circuit cannot be turned on even if the start button is pressed. The editable logic controller fault light is illuminated to evidence the editable logic controller fault. Thus, the load is controlled through the normally open points A6 and K2, and the condition that the contactor malfunctions due to the fault of the editable logic controller is prevented. Thereby improving the accuracy of the action of the actuating mechanism. All loss caused by incorrect operation of the load due to failure of the editable logic controller is avoided.
By adopting the technical scheme, the comprehensive benefits are as follows: the detection unit can randomly detect the working state of the programmable logic controller, the display unit displays and records the technical data of the programmable logic controller and memorizes the reason of the fault when the fault occurs, so that an operator can conveniently and timely overhaul and master the working condition of the combination switch, and the aim of controlling the load system to safely and reliably run by the combination switch is fulfilled; safety benefits are as follows: after the improvement, the actuating mechanism can reliably act, the reliability of safety protection is greatly improved, and the safety of the system is also improved; economic benefits are as follows: after the transformation, indirect economic losses caused by some insecurities are effectively reduced, the maintenance time and the labor cost are saved, and the economic benefit is greatly improved.
