Description
Technical field
The utility model relates to a kind of hoister control device, especially relates to a kind of concrete and stirs the elevator automatic controller.
Background technology
Available coagulation soil stirs in the hoister control circuit, and its travel switch generally can be gone here and there in motor circuit.When concrete stirs elevator work, by upper and lower, stop three buttons and control elevator bucket and move up and down.Because travel switch has load, so in the running, travel switch is easy to burn, and causes hoist engine out of service; Or cause the hoist engine can't be in time out of service, steel is pulled broken, even cause the parts damage.
On the other hand, existing hoist engine is because circuit design is unreasonable, causes operating cumbersome, needs Attended mode, and labor strength is big, work situation is abominable, permanent work, and it is healthy to influence people.
Summary of the invention
The utility model purpose provides a kind of hoister control device.Technical problems such as it is unreasonable to stir the elevator circuit with the solution existing concrete, and travel switch burns, operates cumbersome easily, needs long-term Attended mode, and labor strength is big, work situation is abominable.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: it comprises motor rotating commutation circuit, electromotor control circuit, any two phase lines are connected with the left and right sides power end of electromotor control circuit in the motor rotating commutation circuit, in electromotor control circuit, wherein terminals after the normally opened contact group parallel connection of starting switch and positive contactor are connected with left power end, another terminals pass through travel switch the normally closed interlock group, just the contactor coil is connected to right power end; The normally closed interlock group of travel switch be connected between the power end of the left and right sides after the coil of very first time relay is connected; Wherein terminals after the on-delay contact sets parallel connection of normally opened contact group and the very first time relay of counter-rotating contactor are connected with left power end through the outage delayed contact group of second time relay, are connected with right power end behind the coils from parallel connection of coils circuit of another terminals through the contactor coil and second time relay coil parallel connection formation of reversing.
As preferably, also be in series with the normally-closed contact group of counter-rotating contactor between described positive contactor coil and the right power end.
As preferably, also be in series with the normally-closed contact group of positive contactor between described counter-rotating contactor coil and the right power end.
As preferably, also be in series with shutdown switch between a described left side or right power end and the phase line that is connected this power end.
The utlity model has characteristics such as simple in structure, automaticity height, dependable performance.After concrete stirred hoist installation the utility model, its travel switch is bringing onto load not, and the switching of the rising of elevator bucket and decline finishes automatically, so concrete stirs the elevator fault rate and reduce, and had alleviated labor strength greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is the circuit theory diagrams of the utility model electromotor control circuit.
The specific embodiment
Fig. 1 is the circuit theory diagrams of the utility model electromotor control circuit.It comprises motor rotating commutation circuit 1, shutdown switch SB1, electromotor control circuit 2.In the motor rotating commutation circuit 1, the normally opened contact group K1-3 that passes through positive contactor 41 behind phase line L1, L2, the L3 process power switch Ka respectively is connected with the corresponding binding post of motor M, in addition, the bypass of phase line L1, L2, L3 is connected with the corresponding binding post of motor M through the normally opened contact group K2-3 of counter-rotating contactor 42 respectively.In addition, two phase line L2, the L3 in the phase line is connected with left and right sides power end a, the b of electromotor control circuit 2 respectively, wherein is in series with shutdown switch SB1 between a phase line L3 and the left power end a.
In electromotor control circuit 2, wherein terminals after the normally opened contact group K1-1 parallel connection of starting switch SB2 and positive contactor 41 are connected with left power end a, and another terminals pass through the normally closed interlock group X1 of travel switch 30, just the coil K1 of contactor directly is connected to right power end b.Best, a normally-closed contact group K2-1 of the counter-rotating contactor of connecting between this positive contactor coil K1 and the right power end b.
The normally open contact group X2 of travel switch 30 be connected between left and right sides power end a, the b after the coil KT1 of very first time relay 3 connects.
Wherein terminals after the on-delay contact sets KT1-1 parallel connection of normally opened contact group K2-2 and the very first time relay 31 of counter-rotating contactor 42 are connected with left power end a through the outage delayed contact group KT2-1 of second time relay 32, are connected with right power end b behind the coils from parallel connection of coils circuit 5 of another terminals through the coil KT2 parallel connection formation of the counter-rotating contactor 42 coil K2 and second time relay 32.Best, in this coils from parallel connection of coils circuit 5, the coil K2 of counter-rotating contactor 5 is connected with right power end b by a normally-closed contact group K1-2 of positive contactor 4.
The utility model course of work: press starting switch SB2, the coil K1 energising of positive contactor 41, positive contactor 41 normally opened contact group K1-1, K1-3 closure, normally-closed contact group K1-2 disconnects.Therefore coagulate the motor forward work that soil stirs elevator, drive elevator bucket and rise, contact sets K1-1 keeps this state " pinnings " coil K1 and continues energising, and disconnection K1-2 can allow the off-position of the counter-rotating contactor 42 that cut off the power supply more stable.
Run to the top and batch turning of stirring elevator support when elevator bucket after, clashed into by the collision block of elevator bucket, the normally closed interlock group X1 of travel switch 30 disconnects, normally open contact group X2 closure.So the coil K1 of positive contactor 41 outage, the normally-closed contact group K1-2 of positive contactor 41 recovers closure state.The coil K1 outage relief motor M of positive contactor 41 is out of service, the normally open contact group X2 of the travel switch 30 after the closure allows the coil KT1 of very first time relay 3 switch on, so the on-delay contact sets KT1-1 of very first time relay 31 time-delay (starting behind the 5-7S that normally delays time) closure.At this moment, the coil K2 energising of counter-rotating contactor 32, counter-rotating contactor 42 normally opened contact group K2-2, K2-3 closure, simultaneously, the coil KT2 of second time relay 32 energising, the normally-closed contact group K2-1 of counter-rotating contactor 42 disconnects.Therefore concrete stirs the motor M reverse operation of elevator, the drive elevator bucket descends, in the process that descends, even the collision block of elevator bucket breaks away from travel switch 30, its normally open contact group X2 disconnects, the normally opened contact group K2-2 of counter-rotating contactor 42 also can continue " locking " reverse "on" position of coil KT2 of the coil K2 of contactor 42 and second time relay 32, to keep elevator bucket decline state.
In order to guarantee to stop automatically after stirring the elevator elevator bucket drops to the bottom.Usually, according to the outage delay time (as 25-30s) that second time relay 32 is set fall time that stirs the elevator elevator bucket.Just automatic disconnection behind 25-30s of outage delayed contact group KT2-1 like this, impel the coil KT2 outage of the coil K2 and second time relay of counter-rotating contactor 42, so motor M quits work, elevator bucket drops to the bottom, and the utility model reenters by elevator bucket and treats starting state.
