Structure below in conjunction with the friction-type analogue simulation device of mine hoist of present embodiment illustrates its simulation to the true mine hoist course of work.
1, to the simulation of mine hoist different working modes, the simulation of different working modes is selected by mode conversion switch.
1) automatic operational mode, this pattern is mainly used in the lifting process of colliery main shaft, control procedure according to the mine scene is simulated, pulling speed figure under the automatic operational mode in the present embodiment as shown in Figure 3, suppose that the initial position of hoisting conveyance is positioned at the top of simulation hoistway, promptly need to begin to unload, the major control process is as follows:
Step S101: press the start button in the analogue means, system begins unloading, completion of discharge behind the 6S, bright by the unloaded pilot lamp in the PLC control exterior display device, control of conversion speed setting controller action simultaneously, the operating voltage incoming frequency that promotes motor is transferred to required frequency, make the lifting motor begin to rotate according to described rotation direction, hoisting conveyance begins descending and accelerates in 2S at full speed;
Step S102: when hoisting conveyance runs to descending speed reducing switch, descending speed reducing switch action, the notice PLC process that need reduce speed now, the action of PLC control of conversion speed setting controller, make that promoting motor speed changes, reduce speed now, speed reduces to 20% (promptly 260/1300) at full speed in 2S, begins afterwards at the uniform velocity to descend;
Step S103: when hoisting conveyance moves to down horizontal shutdown switch, this switch motion, PLC control promotes motor and stops operating, and begins to load.Hoisting conveyance is out of service from reducing speed now, need through the downstream position detector switch, at this moment, PLC compares the position of this descending detector switch of writing down in the storage unit and the run location of the hoisting conveyance that the increment type shaft-position encoder records, if error is in allowed band, then continue operation, otherwise system's automatic stopping is also controlled alarm unit and is warned;
Loading finishes behind the step S104:6S, and bright by the fully loaded pilot lamp in the PLC control exterior display device, unloaded pilot lamp goes out, and hoisting conveyance begins up and accelerates at full speed, and control mode and step S101 are similar;
Step S105: when hoisting conveyance went upward to speed reducing switch, hoisting conveyance reduced speed now, and speed reduces to 20% of full speed, at the uniform velocity rose afterwards;
Step S106: out of service after hoisting conveyance moves to horizontal shutdown switch, begin unloading, during can be through the upward position detector switch, S103 is described with step, and the speed and the position of hoisting conveyance are detected;
Completion of discharge behind the step S107:6S, fully loaded pilot lamp goes out, and unloaded pilot lamp is bright, and hoisting conveyance begins descending.
Under this control model, hoisting conveyance goes round and begins again according to the process reciprocation cycle of step S101-step S107.In operational process, travelling speed by PLC control and monitoring hoisting conveyance, guarantee the normal operation of this analogue means, and the travelling speed, acceleration, the moderating process that promote motor design by systems programming, requirement according to pulling speed figure is controlled, can carry out programming Control according to different pulling speed figure by the study personnel, change the method for operation of hoisting conveyance and learn the operating process of skilled analogue means.
2) manual mode of operation, the method of operation of hoisting conveyance is under this pattern: begin to quicken according to the acceleration of setting after pressing start button, can press stop button in operational process at any time makes hoisting conveyance out of service, when pressing start button once more, the system recovery operation, after the deceleration point switch had been passed through in the position of hoisting conveyance, when pressing start button, system moved according to creep speed.
Under manual mode of operation, the control mode of system can adopt start button or stop button directly to link to each other with the lifting motor, directly control promotes the stop and start of motor, promoting motor links to each other with PLC by variable-frequence governor, because PLC has memory function, make to start once more after out of service that system still can continue operation according to pre-set velocity and program.
3) inspection travel pattern, this pattern are the crawl pattern, and the speed of hoisting conveyance is limited in creep speed, and by the working method of PLC control of conversion debugger circuit, and then control promotes the operation of motor crawl.
2, the simulation of mine hoist specific function
In order to ensure the safe operation of mine hoist; need according in " safety regulations in coal mine " (hereinafter to be referred as " rules ") operation of hoister and protection system etc. having been made special regulation; can not put into operation for the mine hoist that can not satisfy regulation, utilize this analogue means that the main protection process in " rules " is simulated below.
1) regulation in the simulation of overtravel protection process, " rules " must be able to be cut off the power supply when hoisting conveyance surpasses orderly shutdown terminal location 0.5m automatically.
This analogue means realizes that the method for aforesaid operations process is; be provided with up pulleying switch and descending pulleying switch (being referred to as the pulleying switch) with the corresponding detection signal panel of simulation hoistway; these two switches lay respectively at the top of horizontal shutdown switch and the below of following horizontal shutdown switch; when hoisting conveyance arrives the position of these two switches; when the situation of pulleying promptly occurring; the pulleying switch motion; the signal that the pulleying situation indication hoisting conveyance occurred sends to PLC; PLC is by the relay of instruction triggers self inside; issue a signal to variable-frequence governor by relay; make its control promote motor and stop operating, and then realize the function of overtravel protection.
2) simulation of overspeed protection process, regulation in " rules ", when the pulling speed of hoisting conveyance surpass maximal rate 15% the time, must be able to cut off the power supply automatically.
This analogue means realizes that the aforesaid operations process is to realize by being arranged on the scrambler that promotes motor shaft end; high-speed counter port by PLC is counted the pulse that scrambler sends; calculate the actual motion speed of hoisting conveyance; and allow travelling speed to compare with maximum that analogue means is set; when actual motion speed exceed maximal rate 15% the time out of service automatically; the control procedure of system and the control procedure of overtravel protection are similar; it is the variable-frequence governor that arrives that PLC sends signal; make its control promote motor and stop operating, finish the overspeed protection function.
3) simulation of speed-limiting protection process, regulation in " rules ", the hoister that surpasses 3m/s when the pulling speed of hoisting conveyance must be provided with the speed-limiting protection device, and hoisting conveyance when arriving parking spot speed must not surpass 2m/s.
The analogue means of present embodiment realizes that the process of speed-limiting protection is; high-speed counter port by PLC is counted the pulse that scrambler sends; calculate the actual motion position of hoisting conveyance; when hoisting conveyance during near parking spot; the maximum permission speed of actual motion speed and setting is compared; when actual motion speed surpassed the pithead position maximum permission speed, it was out of service automatically to promote motor by PLC control, and analogue means stops and cuts off the power supply.
4) regulation in the simulation of deceleration protection process, " rules " when hoisting conveyance arrives the decelerate position of system design, can be warned and reduce speed now.
This analogue means realizes that the simulation of deceleration protection can realize by following two approach:
1. by the high-speed counter port of PLC the pulse that scrambler sends is counted, calculated the run location of hoisting conveyance, after arrival designs decelerate position, control the alarm unit action by PLC, sending slows down warning and control the lifting motor reduces speed now.
2. utilize up slow down switch and the descending speed reducing switch (being referred to as speed reducing switch) that is arranged on the detection signal panel corresponding with simulating hoistway, when hoisting conveyance runs to the speed reducing switch position, switch motion, send the signal that needs deceleration to PLC, report to the police and reduce speed now by PLC control alarm unit afterwards.Certainly, when circuit design, also can directly control alarm unit by speed reducing switch and report to the police, by PLC control of conversion arrangements for speed regulation, and then control promotes motor and reduces speed now, and specifically selects for use which kind of mode to be designed by operating personnel oneself.
5) the sliding rope protection of friction-type mine hoist; friction type winder is the friction force carry-over moment by head roll; and then the action of control hoisting conveyance; when overload or card jar (being that cage is stuck in akinesia in the hoistway) fault occurring; will cause to produce between head roll and the main rope (being the hoist ropes among Fig. 1) and slide promptly sliding rope phenomenon.Sliding rope phenomenon is a kind of breakneck accident, and gently wearing and tearing rope lining then damages head roll, and is heavy then rub main rope and cause hoisting conveyance to weigh down well, and therefore, the sliding defencive function of restricting is vital for the friction-type mine hoist.
The sliding rope defencive function of this analogue means is that the speed of the hoisting conveyance that feeds back of travelling speed and the tech-generator by the lifting motor that scrambler is recorded by PLC compares and realizes; because tech-generator directly links to each other with head roll; therefore the speed of tech-generator feedback is the speed of hoisting conveyance, the just speed of main rope.When according to scrambler to the rate signal value of the lifting motor of PLC feedback and tech-generator to the difference of the rate signal value of PLC feedback during greater than the sliding maximal value of restricting of default, this analogue means automatic stopping also sends alerting signal, wherein the control mode and the top description of parking warning are similar, repeat no more here.
6) position checking and synchronous simulation
1. synchronous.In order to guarantee in the operational process, the error minimum of the calculated value of hoisting conveyance position and actual position value, all will carry out one subsynchronously after lifting process each time finishes to calculating location, synchronizing function is by last horizontal shutdown switch and horizontal shutdown switch (general designation shutdown switch) control realization down in the present embodiment.After the shutdown switch action, the parking spot that the PLC that links to each other with shutdown switch writes setting automatically (is the position of shutdown switch, the physical location of hoisting conveyance parking just), calculated value is changed to actual position value, thereby realize that calculated value and physical location keep synchronously.
It will be appreciated by those skilled in the art that; in theory; synchronizing process also can realize by other modes; as select for use other position detecting switchs all can; when other position detecting switchs of hoisting conveyance process; after the switch motion; system writes the position of the detector switch of setting automatically; calculated value is changed to actual position value; to realize the synchronous of calculated value and physical location, specifically select which position of the switch to carry out synchronously, need actual conditions and the decision of system works situation according to analogue means; but anyway select, all within the protection domain of the utility model embodiment.
2. the check of position, speed.Whether the calculated value of the position of the hoisting conveyance that calculates for the PLC that checks in the hoister operational process and the error of physical location be within allowed band, can send reduce-speed sign timely so that guarantee system, after moving to deceleration point, hoisting conveyance to once check the position and the speed of the hoisting conveyance that calculates, if site error surpasses the error allowed band or actual pulling speed does not in time subtract, system is with automatic stopping and send warning.
Wherein, the judgement of site error can be by going up the physical location of horizontal speed reducing switch and following horizontal speed reducing switch (being referred to as speed reducing switch), the run location of the hoisting conveyance that calculates with PLC compares, and draws site error, compares judgement with the error range that allows; The verification mode of speed can be by behind the hoisting conveyance process speed reducing switch position, the pulling speed of the reality after the deceleration that PLC calculates compares with the preceding actual pulling speed of slowing down, if the pulling speed after slowing down does not change before slowing down, or the error of the rate curve after the pulling speed curve after slowing down and the default deceleration surpasses allowed band, then promote motor by PLC control and stop operating, alarm unit is warned.
7) simulation of cage gate shutdown signal and hoister operating instruction interlock.When the cage gate of hoisting conveyance is in open mode or does not close when putting in place, elevator system can't be sent operating instruction.Describe below in conjunction with the cage gate control system of the analogue means of present embodiment simulation process this function.
