The electric hoist wire detection protection controller has the advantages of high sensitivity, long service life, simple installment, safe and reliable application and simple maintenance.
Description
Technical field:
The utility model is specially adapted to a kind of wired monitoring multi-protection controller of electric hoist of CD/MD type electric block when promoting weight and taking place tiltedly to draw.
Background technology:
Present electric block does not have the anti-control setup that tiltedly draws, rise is to drive switch motion by mechanical device to carry out power down process when transfiniting, there is time-delay, control accuracy is not high, lack easy to wear, malfunctioning, service life, during the rising ultralimit, and the unshielded device control of AC contactor adhesion, as any in the above-mentioned situation takes place, will damage electric block and motor.
Summary of the invention:
Task of the present utility model be propose a kind ofly anti-ly tiltedly to draw, to rise/decline ultralimit, control box in the ac contactor contact adhesion, can both be according to a kind of wired monitoring multi-protection controller of electric hoist of different transducing signal parts or complete machine outage.Task of the present utility model is finished like this, wired monitoring multi-protection controller of electric hoist, it comprises electric appliance control box, motor, it is characterized in that: be connected with anti-oblique pull sensor on the reel outer cover fixed end steel rope, the rising sensor, the rising limit sensor, reel outer cover left side is fixed with the decline sensor, the falling-threshold sensor, the sensor is exported electric signal respectively and is delivered to computing CPU through mouth, computing cpu signal mouth connects the ULN2803 driver module respectively by lead, ULN2803 driver module mouth connects respectively respectively carries out relay, the long closed contact of carrying out on the relay inserts in the loop that exchanges the contact potential coil in the electric appliance control box, and the signal output part of electric appliance control box connects motor respectively.Described execution relay is respectively the CD/MD relay, and CD/MD falling-threshold relay always stops relay, left and right actuated small roadster relay, and left and right big sport car relay is formed.The utlity model has following effect: the utility model by sensor and computing CPU, ULN2803 driver module, carry out relay, electric appliance control box, motor forming control system, the CD/MD electric block is carried out various wired monitorings and defense controls, has highly sensitive, life-span length, easy for installation, safe and reliable, advantage such as easy to maintenance.
Description of drawings:
Fig. 1 is a block scheme of the present utility model.
The drawing explanation; 1, wireless resetting, 2, hand reset, 3, wireless receiving resets, 4, falling-threshold sensor, 5, lower limited sensor, 6, the rising limit sensor, 7, the rising sensor, 8, anti-oblique pull sensor, 9, computing CPU, 10, the ULN2803 driver module, 11, carry out relay, 12, electric appliance control box, 13, motor.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, be connected with on the reel outer cover fixed end steel rope and prevent oblique pull sensor 8, rising sensor 7, rising limit sensor 6, reel outer cover left side is fixed with decline sensor 5, falling-threshold sensor 4, the sensor is exported electric signal respectively and is delivered to CPU 9 computings through mouth, signal output part connects ULN2803 driver module 10 respectively by lead after CPU 9 computings, ULN2803 driver module 10 mouths connect respectively carries out relay 11, the long closed contact of carrying out relay 11 inserts in the loop that exchanges the contact potential coil in the electric appliance control box 12, the signal output part of control box 12 is connected with motor respectively by lead, and above-mentioned execution relay 11 is by the CD relay, the MD relay, CD falling-threshold relay, MD falling-threshold relay, always stop relay, left lateral actuated small roadster relay, right lateral actuated small roadster relay, the big sport car relay of left lateral, the big sport car relay of right lateral is formed.Motor 13 is by CD motor, MD motor, and actuated small roadster motor, big sport car motor are formed.During normal operation, lifting/ lowering sensor 5,7 and anti-oblique pull sensor 8 equal no signals export, the controller testing is normal, the CD motor, the MD motor, the actuated small roadster motor, big sport car motor is carried out lifting/lowering respectively, about operation work, when the electric block liter, when falling the value of overstepping the extreme limit or tiltedly drawing angle to transfinite, the displacement of this moment is passed to lifting sensor 5 by transferring structure, 7, deliver to CPU 9 computings through the input end electric signal, carry out signal shaping, screen, judge, deliver to ULN2803 driver module 10 by mouth after the delay process, tiltedly draw processing signals to deliver to the AC contactor J01 of 12 li of electric appliance control boxes through mouth, thereby cut off CD, MD promotes the power supply and the actuated small roadster motor of motor, power supply on the big sport car motor, the AC contactor J06 that electric appliance control box is 12 li, J07, J08, J09 cuts off the power supply respectively.
When if the adhesion of lifting motor ac contactor contact takes place, the CD motor, the MD motor will work on, driving device on the rising limit sensor 6 still has certain displacement, thereby promoting sensor makes it export the transducing signal that cuts off general supply immediately, judge that through CPU 9 output CD/MD motor cuts off the power supply immediately, quit work, electric block will all cut off the power supply this moment, as recovering machine operation, after the AC contactor of necessary replacing or reparation adhesion, use manual reset switch 2 or press the wireless remote controller 1 that resets, send reset signal and through input end signal is delivered to computing CPU 9 after wireless receiving reseting module 2 receives, make it after new initial optimization, electric block can be from new work.
The design's computing CPU selects PIC micro controller system series of products for use.
