Description
Technical field
The utility model relates to a kind of colliery construction sinking winch control system.
Background technology
At present, the ore deposit is built the Winch control system that each unit in charge of construction uses all the time and is adopted traditional contactless switch-controller control system.This kind control system is simple in structure, and control is convenient.Convenient and practical really in the construction, so continuity is used always.But because colliery construction is long neglected and in disrepair with sinking winch, again for a long time back and forth transportation, use frequent, cause contactless switch can not excellent suction, release, accident appears thereby cause in time stopping, bring certain potential safety hazard for the use of sinking winch.
Present mode starting current can reach 4 to 7 times of rated value, can produce larger impact to line voltage, affects the normal use of other current consumers.
The utility model content
The purpose of this utility model provides the colliery construction of a kind of PLC control use sinking winch control system, this system can not only guarantee to greatest extent the sinking winch safety in operation in the defective that overcomes prior art, and wiring simple, be convenient to keep in repair.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of novel sinking Winch control system comprises winch motor, PLC control unit, and described PLC control unit is used for controlling described winch motor rotating and star-angle starts.
Described PLC control unit comprise the PLC programmable logic controller (PLC) and with the input end of described PLC programmable logic controller (PLC), input equipment, the outdevice that mouth is connected by connection lead respectively, described outdevice is connected with described winch motor.
Described input equipment comprises stop button, forward button, invert button, thermal relay moving together contact; Described outdevice comprises forward control contactor, counter-rotating control contactor, star starting contactor, dihedral starting contactor.
The beneficial effects of the utility model are: 1, adopt PLC control, and safe and reliable, reduced to a great extent rate of breakdown; 2, reasonable in design, the starting current when new control system has reduced electric motor starting, and then minimizing is to the impact of line voltage; 3, wiring topology is simple, for ease of maintenaince.
Description of drawings
Fig. 1 is the circuit diagram that the sinking winch motor positive and inverse that provides of the utility model embodiment and star-angle start;
Fig. 2 is the PLC hardware connection figure that the sinking winch motor positive and inverse that provides of the utility model embodiment and star-angle start.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Fig. 1-2, a kind of novel sinking Winch control system comprises winch motor, PLC control unit, and described PLC control unit is used for controlling described winch motor rotating and star-angle starts.
Described PLC control unit comprise the PLC programmable logic controller (PLC) and with the input end of described PLC programmable logic controller (PLC), input equipment, the outdevice that mouth is connected by connection lead respectively, described outdevice is connected with described winch motor.
Described input equipment comprises stop button SB1, forward button SB2, invert button SB3, thermal relay moving together contact FR; Described outdevice comprises forward control contactor KM1, counter-rotating control contactor KM2, star starting contactor KM3, dihedral starting contactor KM4.
Referring to shown in Figure 1, Fig. 1 shows the circuit theory of control motor positive and inverse and the startup of star angle; For convenience of explanation, only show the part relevant with the utility model.
Referring to shown in Figure 1, the QS1 that closes a switch, plugged is pressed forward button SB2, and contactless switch KM1 coil gets electric, contactless switch KM1 main contact, secondary contact adhesive, electrical power forward; Unclamp forward button SB2, because self-locking, motor still turns round, and presses stop button SB1, contactless switch KM1 outage, and contactless switch KM1 main contact, secondary contact disconnect, and motor stops; Press invert button SB3, contactless switch KM2 coil gets electric, contactless switch KM2 main contact, secondary contact adhesive, and motor gets electric counter-rotating; Press stop button SB1, contactless switch KM2 outage, contactless switch KM2 main contact, secondary contact disconnect, and motor stops.
When electric motor starting, contactless switch KM1 coil gets electric connection, its main contact adhesive, and this moment, motor was star connection, and time relay KT begins timing, and when timing reached the time of setting, time relay KT one contact disconnected, contactless switch KM3 coil blackout; Simultaneously, another closing of contact of time relay KT, contactless switch KM4 coil gets electric, its main contact adhesive, this moment, motor was by transferring the dihedral operation to for the star starting.
Referring to shown in Figure 2, this figure is the PLC interconnecting wiring diagram according to circuit theory shown in Figure 1.At first I/O is distributed, by shown in Figure 2, stop button SB1, forward button SB2, invert button SB3, thermal relay FR moving together contact are connected with the respective input of PLC controller respectively; Forward control contactor KM1, counter-rotating control contactor KM2, star starting contactor KM3, dihedral starting contactor KM4 are connected with the corresponding output end of PLC controller, then carry out the PLC hardware connection that rotating and star-angle starts, at last, write ladder diagram, statement list according to the foregoing circuit schematic diagram, can realize the control of PLC.
The utility model adopts the PLC programmable logic controller (PLC), replaces the relay-contact control circuit by circuit layout and programming.Since PLC in theory can be unlimited simulate adhesive and disconnection, so safety and sensitieness are all much larger than the circuit of relay-contact control.The mode that adopts PLC to switch by star-angle solves directly to open impacts larger problem to electrical network, and can be by adjusting the timer instruction of PLC inside, adjusts the star-angle length of switching time.
The utility model changes PLC control into by the mode with the control winch rotating of contactless switch-controller, because PLC control is safe and reliable, PLC can be unlimited simulate adhesive and disconnection, so safety and sensitieness are all much larger than the circuit of relay-contact control; The PLC mode that adopts star-angle to start in the electric motor starting mode, and can be by adjusting the timer instruction of PLC inside is adjusted the star-angle length of switching time.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
