Abstract
The utility model relates to an automatic agitating reversion control mechanism in a concrete conveying pump, and belongs to the technical field of concrete conveying pumps. The automatic agitating reversion control mechanism is an improvement on the control structure of the hydraulic motor of the prior concrete conveying pump; the corotation and the reversion of the hydraulic motor is controlledthrough replacing the prior mechanical reversing valve into a two-way solenoid valve, so as to control the corotation and the reversion of an agitating shaft; a hydraulic switch is added in an agitating hydraulic pipeline; a signal line is directly connected with the input end of a programmable controller PLC; the corresponding two-way solenoid valve is arranged at the output end of the programmable controller PLC; once locked rotation occurs, the automatic reversion can be achieved under the support of corresponding procedures; and the normal work is recovered after locked rotation factors are removed. The utility model has the advantages of simple structure and strong applicability and effectively improves the safe performance of the concrete conveying pump.
Description
Technical field
The utility model relates to a kind of concrete pump and stirs auto-reverse control mechanism, belongs to technical field of concrete pumps.
Background technique
Concrete pump in the course of the work, the concrete in the hopper needs ceaselessly to stir in order to prevent segregation and to solidify, and on the site, because the size of the building stones in concrete material is inconsistent, very easily causes the stirring shaft stall.Concrete pump on the existing market only provides mechanical type unidirectional stirring shaft rotation, unless the operator finds stirring shaft stall has taken place, by the mechanical switching valve, allows stirring shaft reverse, and allows oversize rock material come off, and stirring shaft could proper functioning.The mechanical switching valve is arranged in the hydraulic control circuit, makes the oil hydraulic motor counterrotating by the flow direction that changes hydraulic oil, if find untimelyly, the concrete in the cylinder will solidify, and the operator must take time and energy is cleaned out buildup.At this type of situation, we propose a kind of stirring automatic control technology, can not only reduce hand labor intensity, but also have improved the automatic control level of complete machine.
Summary of the invention
The purpose of this utility model provides a kind of concrete pump and stirs auto-reverse control mechanism, at only having the unidirectional stirring shaft rotation of mechanical type in the existing concrete transfer pump hopper, in case stall takes place, have only by the mechanical switching valve and reverse by stirring shaft, the deficiency of stirring shaft ability proper functioning after putty is come off, auto-reverse by the utility model realization when stall takes place, recover proper functioning after the eliminating stall factor.
The purpose of this utility model is achieved through the following technical solutions, a kind of concrete pump stirs auto-reverse control mechanism, comprise the stirring hydraulic pipe line, oil hydraulic motor, single-chip microcomputer or programmable controller PLC is characterized in that, in the described hydraulic pipe line hydraulic switch are set, the signal of hydraulic switch connects the input end of single-chip microcomputer or programmable controller PLC through lead, needs two electromagnetic valve coils of the forward and reverse rotation of oil hydraulic motor of control to insert the corresponding output end of programmable controller PLC respectively.
Hydraulic switch adopts open type.
The utility model is the change to existing concrete transfer pump oil hydraulic motor control structure, by being that two way solenoid valves are just being controlled oil hydraulic motor respectively with former mechanical switching valve replacement, counter-rotating, just to reach to stirring shaft, the control of counter-rotating, and in the stirring hydraulic pipe line, increase a hydraulic switch, signaling line directly inserts single-chip microcomputer or programmable controller PLC input end, the output terminal of single-chip microcomputer or programmable controller PLC is corresponding two way solenoid valves, under the support of corresponding program, in case generation stall, can realize auto-reverse, recover proper functioning after getting rid of the stall factor, the utility model is simple in structure, have very strong applicability, effectively improved the Safety performance of concrete pump.
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 the stirring hydraulic pipe line, oil hydraulic motor, and single-chip microcomputer or programmable controller PLC, the hydraulic switch S1 that is provided with in the hydraulic pipe line, hydraulic switch S1 adopts open type.The signal of hydraulic switch connects the input end of single-chip microcomputer or programmable controller PLC through lead, needs the coil of two solenoid valve Y1, Y2 of the forward and reverse rotation of oil hydraulic motor of control to insert the corresponding output end of single-chip microcomputer or programmable controller PLC respectively.Solenoid valve Y1, Y2 adopt.
Former mechanical switching valve replacement is two way solenoid valve Y1, Y2, control the forward and backward of oil hydraulic motor respectively, to reach control to the stirring shaft forward and backward, in stirring hydraulic pipe line, increase a hydraulic switch S1, signaling line directly inserts programmable controller PLC input end, and the output terminal of programmable controller PLC is the coil of control corresponding two way solenoid valve Y1, Y2.During operation, if when allowing oil hydraulic motor be operated in the state of " just changeing ", solenoid valve Y1 coil gets, when stirring shaft generation stall, the oil pressure value that stirs hydraulic pipe line raises, when pressure was elevated to setting value, hydraulic switch S1 closure was when PLC detects this switching signal, its output control electromagnetic valve Y1 coil losing electricity, the force value of hydraulic tubing is descended, and solenoid valve Y2 coil gets electric, keeps Y1 to get electric 5-6 second by the time relay, hydraulic switch S1 disconnects, solenoid valve Y1 gets electric, and solenoid valve Y2 dead electricity is recovered " just changeing " state again simultaneously; In like manner, if when allowing oil hydraulic motor be operated in the state of " counter-rotating ", solenoid valve Y2 coil gets, when stirring shaft generation stall, the oil pressure value that stirs hydraulic pipe line raises, when pressure is elevated to setting value, and hydraulic switch S1 closure, when PLC detects this switching signal, its output control electromagnetic valve Y2 coil losing electricity, solenoid valve Y1 coil gets electric, and the force value of hydraulic tubing is descended, keep Y1 to get electric 5-6 second by pressure relay, hydraulic switch S1 disconnects, and solenoid valve Y2 gets electric, simultaneously solenoid valve Y1 dead electricity, again recover " counter-rotating " state, thereby realized auto-reverse function.
