Embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment:
Accompanying drawing 1-4 can know; A kind of composite type control of soft device; Major loop comprises: insulating phase-change switch GHK, Group of Silicon Controlled Rectifier KGZ, bypass contactor PK, B road contactor BK, C road contactor TK; Main power source is divided into two groups of parallel lines through silicon controlled component KGZ again through insulating phase-change switch GHK: one group of A machine lead-out terminal with control master rotor motor is connected; One group of process contactor BK is connected with the B machine lead-out terminal of control auxiliary cylinder motor; C route GHK load side is told, and is used to control hydraulic pressure and carries the straight of brake gear and rise, directly stop, and the said lock control circuit of carrying is by hydraulic brake comprehensive protector of motor JDB, power-off delay relay LJ with carry lock contactor TK and form.
Its auxiliary contact was closed after the said soft start control system of carrying lock contactor TK and multi-functional soft start controller SDRK was provided with the TK adhesive, and the soft start control system of multi-functional soft start controller SDRK could get the electrical interlock circuit that the electrician does; Soft delay time of the start of said soft starting controller SDRK put forward the lock speed of putting forward that brake gear gets after electric according to hydraulic pressure and confirmed; The shutdown delay time of said time-delay relay LJ is used to the power size according to the shutdown of on-the-spot belt feeder and is confirmed.
The utility model composite type control of soft device can reduce the platform number of belt feeder institute electrical installation, the volume and weight that dwindles the used soft starter of belt feeder, the belt feeder that takes up room, effectively prolongs that dwindles electric equipment and carry the useful life of brake gear, ensures the safe handling of belt feeder, the supply line of having simplified belt feeder.
The utility model composite type control of soft device can dwindle taking up room of electric equipment, effectively prolongs the hydraulic test life-span, ensures the safe handling of belt feeder, simplified power supply circuits.
The utility model composite type control of soft device is provided with the major-minor Rolling motor that A, two major loops of B control belt feeder respectively, and the C road that capacity 5A is set is used for controlling two hydraulic brake motors of belt feeder.When soft starter was driven, the control system of hydraulic brake motor got the electrician earlier and does, and the adhesive of small size vacuum contactor TK elder generation is two hydraulic brake motors power supplies, and hydraulic brake unclamps.The SDRK controller can be provided with soft the time-delay of 0-10s, can guarantee to begin soft start again after carrying lock puts in place.And the soft start control system of TK contactor and soft starter is provided with electrical interlock; Its auxiliary contact is closed after having only the TK adhesive; The soft start system of soft starter could get the electrician and do; When preventing that putting forward the lock control system breaks down cisco unity malfunction, soft start puts into operation under the situation of not carrying lock and damages hydraulic pressure and carry brake gear.
When soft starter stops, A, the outage earlier of two major loops of B, two Rolling motor outages of belt feeder.Selected outage time-delay release relay for use because of the LJ relay of control TK contactor adhesive, so LJ relay outage back time-delay (0-5s is adjustable) discharges, the time-delay of TK vacuum contactor discharges belt feeder hydraulic brake motor delay cut-off band-type brake.Being used to the shutdown time-delay band-type brake time that the power size is set up hydraulic brake in the time of so just can shutting down according to on-the-spot belt feeder can reduce greatly to shut down and be used to the damage of power to hydraulic brake, prolonged the useful life of hydraulic brake device greatly, ensured the safe handling of belt feeder.Behind the C road control hydraulic brake with soft starter, the belt head can have been simplified power supply less with 1 80A Vacuum Magnetic explosion-proof switch, has dwindled taking up room of electric equipment.
The course of work of the utility model composite type control of soft device is following:
The insulating phase-change switch GHK that closes, power transformer DB gets electric, and output AC220V is multifunctional soft starter controller SDRK power supply, and it is closed that SDRK gets electric back its fault contact KB2, communication interface output DC12V intrinsic safety electric source.
Press starter button during driving, 12V relay K J gets electric adhesive, KJ: the two groups of closures of often making war in (3,5) (4,6); Connect the operating circuit of AC24V relay LJ and ZJ, LJ gets electric adhesive, LJ: (3,1) junction closure; Connect the operating circuit of AC220V vacuum contactor TK, the TK contactor gets electric adhesive, and A machine, C machine earth leakage search/lockout withdraw from; The hydraulic brake motor of major and minor two cylinders gets the electrician and does, and the hydraulic brake of two cylinders is unclamped; After ZJ gets electric adhesive, ZJ: (3,5) junction closure, the operating circuit of connection AC24V relay R J.After RJ gets electric adhesive, RJ: (4,6) junction closure, the holding circuit of connection KJ, start button unclamps; RJ: (3,5) junction closure; With closed TK: the connect start-stop signal input terminal of connection SDRK of (23,24) contact: (A12, A13); Lead-out terminal through SDRK after the soft start time-delay of setting begins to export A, B, C, A ', B ', C ' six group pulse trigger voltages; Group of Silicon Controlled Rectifier KGZ begins conducting gradually, and the master rotor motor that the A machine is controlled gets electric soft start to begin.KB01 junction closure in the while SDRK, the operating circuit of connection AC24V relay BJ is after the BJ adhesive; BJ: (3,5) junction closure is connected the operating circuit of AC220V vacuum contactor BK; After the BK adhesive, the auxiliary cylinder motor that the B machine is controlled gets electric soft start to begin, and B machine earth leakage search/lockout withdraws from.When reaching soft time of setting, the KB1 bypass junction closure in the SDRK, ZJ: (4,6) are closed; AC24V relay PJ gets electric adhesive; PJ: (3,5) junction closure is connected the operating circuit of AC220V vacuum contactor PK, and after the PK adhesive, soft starter begins the operation of bypass full voltage; SDRK stops to send trigger voltage to Group of Silicon Controlled Rectifier behind the 600ms, and controllable silicon ends.
Press stop button during parking, the KJ relay electric-loss discharges, and KJ (3,5) (4,6) contact breaks off; LJ, ZJ relay cut off the power supply simultaneously, and the ZJ relay discharges at once, ZJ: (4,6) contact breaks off; The PJ relay electric-loss discharges; PJ: (3,5) contact breaks off, and the PK contactor discharges, and A machine master rotor and B machine auxiliary cylinder motor cut off the power supply simultaneously and shut down.Because the LJ relay is an outage time-delay release relay; The time-delay (like 2s) that will pass through setting after cutting off the power supply simultaneously with the ZJ relay just discharges; LJ: (3,1) contact breaks off, and the TK contactor discharges, and two hydraulic brake motors of major and minor cylinder cut off the power supply simultaneously and shut down; Hydraulic brake is held tightly, and belt feeder stops operating.
