Description
Technical field
The present invention relates to solenoid actuated control circuit, be specifically related to a kind of two ends solenoid actuated control circuit.
Background technology
Electromagnet is that electric energy is converted to electromagnetic energy, then electromagnetic energy is converted to the device of mechanical energy.The element of electromagnet and operation principle are mostly identical, are generally made up of coil, fixed core (yoke) and moving (armature) three major parts unshakable in one's determination.When coil is by after the electric current of certain value, in fixed core, moving iron core and air gap, just produce the magnetic flux of some, and then ferromagnetic material is produced to a certain size electromagnetic attraction, will move unshakable in one's determination suction to fixed core, when after the current stops in coil, electromagnetic attraction also disappears very soon.
The most DC power supply that adopt of electromagnet, general electromagnet is all unidirectional electrical magnet, this unidirectional electrical magnet is far from suitable to the reciprocating motion of parts, so have electromagnet or the push-pull electromagnet of the clear bi-directional drive of human hair, but these two-way electromagnet are all that the moving iron core of an electromagnet can forward and reverse direction be moved in essence.For example number of patent application is 201310243372.2, and name is called the application for a patent for invention of " electromagnet drive circuit in bi-directional ", discloses a kind of electromagnet drive circuit in bi-directional.Comprise main circuit and control circuit, wherein: the 48V direct voltage in main circuit is connected with filter circuit, H bridge operating circuit, protection and current-limiting circuit successively, finally connects electromagnet; In control circuit, Single Chip Microcomputer (SCM) system is sent two-way pwm signal He Yi road direction signal, convert with the reverse isolation of buffer circuit and amplify by logical circuit, convert four tunnel control signals to, wherein MOSFET drive circuit of two-way control, another another identical MOSFET drive circuit of two-way control, MOSFET drive circuit is connected with H bridge operating circuit, and parameter regulating circuit is connected with Single Chip Microcomputer (SCM) system.Thereby this invention proposes to drive H bridge to control the positive and negative motion of electromagnet with PWM, but the moving parts of its control be single can bidirectional-movement part, this same electromagnet moved toward both direction, for trailed parts, be one-sided stressed, result is parts or tension, pushed away, there are many deficiencies in single like this pushing away or draw, if promote a soft pole or rope, effect is certainly bad: how this soft rope pushes away, if rope is connected to a side who draws, limit installation mobility, and rope also will be return reset after all, when reset, still need to push away, this has produced again new problem.And then, prior art be the designed unidirectional or two-way control circuit of this single electromagnet, be not applicable for carrying out the paired electromagnet of push-and-pull from two ends.
Summary of the invention
The technical issues that need to address of the present invention are, overcome prior art for the designed unidirectional or two-way control circuit of single electromagnet is for the not applicable defect of paired electromagnet of carrying out push-and-pull from two ends, a kind of control and operating circuit of carrying out the paired electromagnet of push-and-pull combination from two ends is provided.
The object of the invention is to be achieved by following technical proposals: a kind of push-pull type electromagnet traction control circuit, comprise left electromagnet, right electromagnet, contactor, travel switch, left electromagnet is connected DC power supply with right electromagnet by operating circuit, and by control circuit control; Left magnet spool TS1 is connected with power supply with right magnet spool TS2 parallel/series again, and coil TS1 is identical with the pole orientation of coil TS2; Operating circuit is configured to: one end of the coil of parallel/series is connected by the contact KM11 of contactor KMI and the anodal A of power supply, and be connected by the contact KM21 of contactor KM2 and the negative pole B of power supply, the other end of the coil of parallel/series is connected by the contact KM12 of contactor KMI and the anodal A of power supply, and is connected by the contact KM22 of contactor KM2 and the negative pole B of power supply; Have a duplex button QSB for starting, a pair of contact QSB1 of duplex button QSB is in parallel with contact KM21, and another of duplex button QSB is in parallel with the two ends of contact KM22 to contact QSB2; The formation of control circuit is: one end of contactor KM1 is connected with positive source, and the other end of contactor KM1 is connected with power cathode by travel switch SQ1, in parallel with travel switch SQ1 two ends again after having chain contact KM13 and insuring contact KM24 series connection; One end of contactor KM2 is connected with positive source, and the other end of contactor KM2 is connected with power cathode by travel switch SQ2, in parallel with travel switch SQ2 two ends again after having chain contact KM23 and insuring contact KM14 series connection; Often open class contact KM11, KM12, KM13 and normally closed class contact KM14 and controlled by contactor KM1, often open class contact KM21, KM22, KM23 and normally closed class contact KM24 and controlled by contactor KM2.
