Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, present embodiment provides a kind of hoisting device performance test simulation system, and it comprises load motor, load inverter, Programmable Logic Controller, flexible band, tension pick-up, lifting motor, the frequency converter that hoists, master controller and rotary encoder.
Load with reference to hoisting device is typical constant force load, is can not change in whole lifting process, and load request is variable, and big especially.Simulate the key that this kind load is whole Performance Test System, original method can only be to be hung in aerial weight, the present invention simulates the method for this kind load for using motor to dragging as fictitious load, therefore, lifting motor in the said system links to each other by the flexibility band with the output of load motor and realizes dragging, in order to keep the constant of two power between the motor, load motor working load Frequency Converter Control in this system, and load inverter operates in permanent tension mode (being also referred to as).Load motor power can be tested as required and select the different capacity section.So just can save huge boom hoisting, reduce the volume of system.
Be equipped with master controller and Programmable Logic Controller in the native system control, wherein Programmable Logic Controller one tunnel is electrically connected load inverter, and load inverter output is electrically connected and drives load motor; Another road of Programmable Logic Controller is electrically connected master controller, and master controller is electrically connected the frequency converter that hoists, and the frequency converter that hoists output is electrically connected and drives lifting motor.Thereby master controller operation can be manually used in the operation of system, also can expand the Programmable Logic Controller expansion of programming, and makes test can reach robotization and tests in 24 hours.
The flexibility of connection load motor and lifting motor is with and is added tension pick-up, and tension pick-up is electrically connected load inverter and Programmable Logic Controller, thereby makes load can carry out visual electrodeless adjustment.And can simulate unusual load sudden unloading process.
On the operation axle of lifting motor, then install interlock additional orthogonal encoder (1000P/R) is arranged, this orthogonal encoder is a kind of of rotary encoder, it is electrically connected to Programmable Logic Controller, make Programmable Logic Controller to obtain system running speed at any time and move total distance information, in addition, rotary encoder can cooperate the time sequential routine of master controller to detect, and can in time detect the initial launch state of system, and these states are often ignored by the people because life period is very short.
Be native system one embodiment as Fig. 2,3.Wherein Fig. 2 starts schematic diagram for Performance Test System, and major loop is connected to lifting motor by A.C. contactor QM1.The 380V electricity uses for control loop through obtaining the 48v direct current after the transformation.At first enable SA1, total contactor KM gets electric closure, all devices normal power supply.Among Fig. 3 on the master controller one grade for rising switch 1KA5, receive on the X1 contact, descends one grade be decline switch 1KA6, receive on the X2 contact.And be equipped with on the rising switch 1KA5 rising auxiliary reclay control loop that weight is spacing, moment is spacing and spacing three protective devices of superelevation.Get to the 2nd grade or when above at master controller, hoist frequency converter successively closed input terminal X3/X4/X5/X6 carry out the control of multistage speed.The frequency converter that hoists detects opens band-type brake signal TA-TC automatically when meeting the band-type brake release conditions, enter the operation phase, and when stopping, the frequency converter band-type brake TA-TA auto-closing that hoists carries out band-type brake.
Fig. 3 is the load motor elementary diagram, load inverter operates in the current phasor torque mode, and tension force is set with the AI1 analog input, and online change constantly, vector moment mode operation can reach real permanent tension force operation, and it doesn't matter with travelling speed and direction.So can perfectly simulate the rise and fall operation of crane.Tight being with that is connected between load motor and bridge motor is equipped with tension pick-up, can detect tension variation constantly, sudden change is little as long as tension force detects tension force, close to 0, just explanation has the generation of slide hook phenomenon, and the switching that can simulate repeatedly hoists descends comes repeatedly the stability of test macro.
If be the research and development test initial stage, can use master controller to debug repeatedly, make things convenient for viewing effect, can cancel master controller during follow-up batch testing, replace with Programmable Logic Controller, and the variation of reading the tension force detection module constantly, read the encoder pulse amount, record ruuning situation reaches the full-automatic testing state that nobody waits for, and makes things convenient for batch testing to use.
Use flow process
1, open switch QF2, load inverter gets electric, and load inverter operates in torque mode, and given moment size is the AI1 analog input, regulate just direct control load power size of RR value, and sizes values can directly observe at tension pick-up.
2, open switch QF, QF1.Total system gets.
3, enable the SA1 button, the KM main relay gets electric adhesive.
4, master controller is got to and is risen one grade the time, and IS1 enables, when weight spacing, moment is spacing, and superelevation is spacing when being failure to actuate, frequency converter rising switch 1KA5 action, the contact action of rising switch 1KA5 is connected the frequency converter that hoists and is just being changeed rising signals input port X1, and frequency converter gets startup command, after moving to band-type brake and opening frequency, the closed output of band-type brake opening signal TA-TC, the KA2 coil gets, contact 1KA2 closure, the brake relay KM1 that hoists gets electric, and band-type brake unclamps, and frequency converter normally moves rising.If it is spacing to run into weight in the frequency converter uphill process, moment is spacing, the spacing action of superelevation, and then frequency converter rising run signal disappears, and frequency converter stops automatically.
5, master controller is got to and is descended one grade the time, and IS2 enables, frequency converter down relay 1KA6 action, and frequency converter counter-rotating dropping signal input port X2 is connected in 1KA6 action in contact, and frequency converter must start the order that descends.The wait band-type brake is opened after moving to the band-type brake frequency.The closed output of band-type brake opening signal TA-TC, the KA2 coil gets electric, contact 1KA2 closure, the brake relay KM1 that hoists gets electric, and band-type brake unclamps, and frequency converter normally moves decline.
If when meeting fault midway, frequency converter failure relay BRA-BRC conducting, the 1KA1 coil gets electric, and contact 1KA1 disconnects, band-type brake relay 1KM1 dead electricity, the mechanical hatching gate auto-closing prevents from slipping hook.Enable the SA2 fault that resets after stable.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
