Description
Technical field:
The utility model relates to crystallization salt pond, saltern electromechanical integration and moulds the equipment of covering with mat, and particularly a kind of salt pond is moulded and covered automatic control device with mat.
Background technology:
At present the salt pond moulds to cover with mat and does not possess automatic controlled function, the operation of equipment leans on operator in the point of fixity manual operation fully, because two motors of hitch wheel and the floating spool of traction all connect the operation of power frequency (50Hz) power supply, during folding and unfolding, the diameter of reel is increasing, and the diameter of floating spool is more and more littler, makes folding and unfolding asynchronous.During operation, must manually frequently alternately start and stop two drive-motor and control the folding and unfolding speed of moulding tarpaulin, make it keep certain rate of tension.Therefore prior art exists following defective and deficiency:
1, during folding and unfolding, moulds tarpaulin and be difficult to realize true synchronization, pine, tension phenomenon often occurred.Spend when pine, mould tarpaulin and produce viscous deformation, even drawing crack, traction rope snaps and float spool and pull out, fracture from embracing in the roller.
2, frequent starting two motors can cause the shock load of motor overheating, machine driven system excessive, reduce the work-ing life of transmission system and traction rope.
3, motor intermittent operation has reduced running efficiency of system.
4, the operator can only be in the salt pond one jiao machine room internal fixing ground point operation, the operation conditions that is difficult to accurate viewing system, thereby, need several support personnel to pay close attention to operation conditions in many places such as embracing roller, track inlet respectively, unforeseen circumstances occurs, send signal and give the operator.It is wrong or untimely that signal receives, and then often causes fault to take place even can not in time shut down and cause the fault state of affairs to enlarge.
Summary of the invention:
Goal of the invention of the present utility model provides a kind of salt pond with following function and moulds and cover automatic control device with mat:
1, adopts stepless speed regulation, realize moulding the tarpaulin exhibition and put and draw whole-process automatic coordination control;
2, adopt telechirics, realize moulding the telemanipulation of the system of covering with mat;
3, adopt real-time detection apparatus, realize online detection, trouble diagnosis and the warning of system running state.
The technical scheme that realizes the foregoing invention purpose is: this salt pond is moulded and is covered automatic control device with mat and be made up of the reel that constitutes mechanical part, reel motor, traction rope, floating spool, floating reel motor and the PLC, frequency transformer, telepilot, transmitter etc. that constitute electrical appliance part.In the mechanical part, the reel front portion is provided with the reel sampling mechanism, the fixed support of this mechanism be provided with along drum shaft to crossbeam, lifting trolley shape sliding support on the crossbeam, the sampling cylinder is housed on this sliding support, this cylinder side is evenly equipped with the induction screw along its circumferential direction, and by with its fixed support arm the reel sensor that cooperates with this screw induction being housed, traction rope is pressed on this cylinder and pure rolling connection with it on the drum shaft; Floating spool top is provided with floating spool sampling mechanism, be hinged with swivel arm on the vertical columns of this mechanism, on the swivel arm by the sampling cylinder being housed with its fixed support, this cylinder side is evenly equipped with the induction screw along its circumferential direction, by with its fixed support arm the floating reel sensor that cooperates with this screw induction being housed, this cylinder is that pure rolling is connected with the floating spool of its below on the drum shaft.In the electrical appliance part, the analog quantity delivery port of PLC is connected with the respective input mouth of frequency transformer with the RS485 mouth, the L1 of this frequency transformer, L2, L3 output port are connected with the reel motor by the main power circuit steering logic, its U, V, W output port are connected with floating reel motor, the Din mouth of PLC is provided with telepilot and sensor signal interface circuit, and its Dout mouth is connected with warning device with pilot circuit.
Transmitter is made up of reel sensor and floating reel sensor, is used for detecting the displacement signal that reel outer rim traction rope and floating spool outer rim are moulded tarpaulin respectively, and signal is delivered to PLC.The operational order of the button that the projector of telepilot is pressed the operator is transformed to radio wave transmission and goes out, and receiving apparatus receives this radio wave signal, and converts corresponding instruction to and output to PLC.PLC has four effects: the one, and the signal that operational order that the reception telepilot is sent here and transmitter are sent here, calculate the line position of reel winding and the length of moulding tarpaulin that floating spool is emitted, let slip bit shift compensation rule and synchronous speed control law in the journey according to exhibition, determine motor operation line frequency, and export this numerical value to frequency transformer by analog quantity delivery port and RS485 mouth; The 2nd, as the interface circuit of telepilot, finish the steering logic of complex operations, realize the function expansion of telepilot; The 3rd, combine with transmitter, realize online detection, trouble diagnosis and the warning of system running state; The 4th, according to the requirement of system's running, control the break-make of main power circuit steering logic by the peripheral hardware pilot circuit.Frequency transformer converting power source frequency, its frequency values is controlled by the analog quantity size of the analog quantity delivery port output of PLC or by the digital quantity size of PLC mouth output, and then the rotating speed of control reel motor and floating reel motor, realizes the stepless speed regulation of motor.
The utility model is compared with background technology, has the following advantages:
Because frequency transformer can be realized the stepless change of motor, the scheme of being made up of PLC, transmitter, frequency transformer has realized moulding the true synchronization of tarpaulin folding and unfolding, it is constant that the rate of tension of moulding tarpaulin is remained, not loose not tight, the cloth problem neither can appear tearing, can not make yet and mould that tarpaulin produces that viscous deformation, traction rope are snapped, floating spool is from embracing phenomenon such as pull out, fracture in the roller, reduced rate of breakdown, reduce maintenance load, improved the work-ing life and the reliability of system operation of moulding tarpaulin, traction rope, floating spool.
After the motor stepless change, keep folding and unfolding synchronous by regulating motor speed, the motor continuous operation, working load is stable, the greater impact load of having avoided the frequent start-stop in the existing operation to bring to system, the work-ing life of having improved transmission system.
Because system's continuous operation, wholely cover the time and shorten to 15 minutes by 20 minutes of existing discontinuous running mode, improved and covered efficient.
Use telemanipulation, operator's operation is not subjected to site limitation, and the visual field is wide, is convenient to the system of supervision operation conditions.
