Abstract
The utility model relates to an automatic idle speed control mechanism for a diesel engine in a concrete conveying pump, and belongs to the technical field of concrete conveying pumps. The concrete conveying pump is characterized in that a pumping state switch is connected to the input end of a single chip or a programmable controller PLC, and a direct current coil for controlling a throttle actuator is connected to the output end thereof; after an operator selects the positive pump or the negative pump of the pumping state switch and the input end of the PLC receives signals, the output end of the PLC is connected to the corresponding direct current coil for controlling the throttle actuator, so that the actuator carries out corotation and the rotating speed of the diesel engine is increased; and after the operator cuts off the pumping state switch and the input end of the PLC receives the signals, the output end of the PLC is connected to the corresponding direct current coil for controlling the throttle actuator, so that the actuator carries out reversion and the rotating speed of the diesel engine is reduced to an idle speed state, thereby achieving the automatic idle speed function of the diesel engine.
Description
Technical field
The utility model relates to diesel engine auto idle speed control mechanism in a kind of concrete pump, belongs to technical field of concrete pumps.
Background technique
Concrete pump when the operator need carry out pumping, will transfer to rated speed to diesel engine speed earlier in the course of the work, could start working by closed pumping switch; When finishing pumping, behind the disconnection pumping switch, again diesel engine speed is reduced to idling.Because in the pumping process, concrete in the material cylinder need constantly add material, the operator can disconnect the pumping switch when adding material, avoided air to enter in the pump concrete pipeline, but can not reduce to idling to diesel engine speed sometimes, after adding honest material, work on again, if transfer pump continuous operation 10 to 12 hours, having similar 1 hour is the stand-by period, and the oil consumption of diesel engine wastes, but require the operator to add material at every turn and cut off the pumping switch, speed drop to idling, add honest material after, again rotating speed is transferred to rated speed, open the pumping switch, work on again.In the continuous operation, each hour needs add material 50 to 60 times, so increase operator's labor intensity beyond doubt.
Summary of the invention
The purpose of this utility model provides diesel engine auto idle speed control mechanism in a kind of concrete pump, need the operator to add material at the existing concrete transfer pump and cut off the pumping switch, speed drop to idling, after adding honest material, again rotating speed is transferred to rated speed, open the pumping switch, the deficiency that has the labor intensity that has increased the operator, diesel engine enters idling mode automatically after realizing stopping pumping by the utility model, thereby can not only reduce operator's labor intensity, cut down the consumption of energy, but also the automatic control level of raising complete machine.
The objective of the invention is to be achieved through the following technical solutions, diesel engine auto idle speed control mechanism in a kind of concrete pump, comprise single-chip microcomputer or programmable controller PLC, it is characterized in that, between two input ends of described single-chip microcomputer or programmable controller PLC and the ground and connect the pumping status switch, two output terminals of single-chip microcomputer or programmable controller PLC connect the dc coil of control throttle actuator.
Described pumping status switch adopts three-position switch.
The utility model inserts the pumping status switch by the input end at single-chip microcomputer or programmable controller PLC, the dc coil that connects the control throttle actuator at its output terminal, after the operator selects pumping status switch " positive pump " or " anti-pump ", after the PLC input end receives signal, the dc coil that the PLC output terminal is connected to the control corresponding throttle actuator just changes final controlling element, increase diesel engine speed, after the operator cuts off the pumping status switch, after the PLC input end receives signal, the dc coil that the PLC output terminal is connected to the control corresponding throttle actuator makes the final controlling element counter-rotating, diesel engine speed is reduced to idling mode, realizes diesel engine auto idle speed function.
Description of drawings
Fig. 1 is the utility model circuit connection diagram;
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model comprises single-chip microcomputer or programmable controller PLC, be programmable controller PLC in the present embodiment, between two input ends of programmable controller PLC and ground and meet pumping status switch SA1, the pumping status switch adopts three-position switch.Two output terminals at programmable controller PLC connect the dc coil M1 that controls throttle actuator,
During work, after the operator selects pumping status switch SA1 state (" positive pump " or " anti-pump "), after the PLC input end receives signal, the dc coil M1 that the PLC output terminal is connected to the control corresponding throttle actuator just changes final controlling element, increase diesel engine speed, after the operator cuts off the pumping status switch, after the PLC input end receives signal, the PLC output terminal is connected to the dc coil of control corresponding throttle actuator, make the final controlling element counter-rotating, diesel engine speed is reduced to idling mode, realizes diesel engine auto idle speed function.
