Description
Technical field
The present invention relates to a kind of Crushing Station power control system, relate in particular to a kind of crawler-type mobile Crushing Station power control system.
Background technology
At present, the broken control system of the dynamical system of known mobile crushing station is mainly taked directly to realize with external three phase mains drive motors for broken motor, relatively independent with the control of other motors, workload to disintegrating machine is uncontrollable, load affects the efficient of motor when too low, the phenomenon of low load with strong power occurs.When load too high, cause motor load overweight and cause motor to damage.
Summary of the invention
Deficiency for the load of the uncontrollable disintegrating machine of dynamical system that overcomes existing mobile crushing station the invention provides a kind of crawler-type mobile Crushing Station power control system.
The technical solution adopted for the present invention to solve the technical problems is: crawler-type mobile Crushing Station power control system, comprise broken control system and traveling control system, described broken control system involving vibrations motor, broken motor, main motor and the secondary motor of carrying carried; Described crawler-type mobile Crushing Station power control system also comprises master board, and master board is connected with traveling control system with broken control system; Described broken control system also comprises the first frequency converter and the second frequency converter, the first frequency converter be connected the input of frequency converter and be connected with controller, broken motor is connected with the output of the first frequency converter, vibrating motor is connected with the output of the second frequency converter, and the Current Mutual Inductance sensor that the first frequency converter carries is connected with master board.
Further, described traveling control system comprises proportional amplifier plate and hydraulic moving proportioning valve, and described hydraulic moving proportioning valve is connected with proportional amplifier plate, and proportional amplifier plate is connected with master board.
The invention has the beneficial effects as follows: the load of the disintegrating machine of crawler-type mobile Crushing Station can be controlled at the preset value of setting, can not produce the disintegrating machine excess load and damages the phenomenon that motor or underload affect electric efficiency, reduces energy consumption.
Description of drawings

Fig. 2 is crawler-type mobile Crushing Station power control system governor circuit figure of the present invention.
Fig. 3 is crawler-type mobile Crushing Station power control system motor circuit figure of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Shown in Figure 3 such as Fig. 1, crawler-type mobile Crushing Station of the present invention adopts electrohydraulic mixed power, and power control system comprises traveling control system and broken control system.Traveling control system adopts the motor driven hydraulic system to realize, and broken control system adopts the three phase mains drive motors to realize.
The broken control system of crawler-type mobile Crushing Station: main involving vibrations motor, broken motor, main motor and the secondary motor of carrying carried.Wherein broken motor by the first Frequency Converter Control, vibrating motor by the second Frequency Converter Control.Use Frequency Converter Control, both realized the at the uniform velocity acceleration starting of motor and ramp to stop at the uniform velocity, guarantee operating steadily of equipment, reduce again the electric current of starting, reduce energy consumption, reduce simultaneously the requirement to external power supply.
The used frequency converter maximum effect of the present invention is exactly the electric current that detects motor by the Current Mutual Inductance sensor that frequency converter carries.Detect the current conditions of broken motor during normal operation by the Current Mutual Inductance sensor of the first frequency converter, the current signal that detects is passed to master board, thereby calculate the workload situation of motor.When detecting load above preset value, control panel will reduce the output frequency of the first frequency converter, and then reduce the running speed of broken motor, detect again the loading condition of broken motor this moment, still be higher than preset value such as crusher load, control panel then reduces the output frequency of the second frequency converter, and the rotating speed that reduces vibrating motor reaches the effect that reduces delivery rate.Again detect the loading condition of broken motor, if when the load of broken motor still surpassed preset value, control panel continued to reduce the output frequency of the second frequency converter, reduce delivery rate, until reach balance, even feed stops.In like manner, when the broken motor load that detects during less than preset value, control panel improves the output frequency of the second frequency converter, strengthens vibrating motor speed.Again detect the loading condition of broken motor, if the load of broken motor is still less than preset value, continue to improve the output frequency of the second frequency converter, thereby increasing delivery rate, but the speed of vibrating motor strengthens limes superiors is arranged, when arriving limes superiors, just stop to improve the output frequency of the second frequency converter in order to avoid strengthen delivery rate.When if the rotating speed of vibrating motor reaches higher limit, broken motor load value does not also arrive preset value, then improves the output frequency of the first frequency converter to strengthen the output speed of motor of crusher, until the motor of crusher load is normal.
Further, crawler-type mobile Crushing Station traveling control system uses the motor driven hydraulic system to realize, comprise proportional amplifier plate and hydraulic moving proportioning valve, speed control during walking is the stepless adjustment of ratio that realizes speed by automatically controlled proportional amplifier plate control hydraulic moving proportioning valve, the principle of hydraulic moving proportioning valve is exactly the priority traffic that guarantees walking, all the other flow shunt oil sump tanks.The common proportion control that existing traveling control system uses is the preferential speed that guarantees walking, and remaining flow is through the oil return of overload overflow protective valve, and this situation is exactly the maximum load overload, causes system's heating to waste simultaneously power.Use simultaneously proportion control can realize the even at the uniform velocity ramp to stop that accelerates to start to walk, realized operating steadily of walking.Walking turns to control to adopt two driving, and realizes large torsion and minimum operating radius.
The present invention is not limited to above-mentioned preferred forms, and other any identical with the present invention or akin circuit that anyone draws under enlightenment of the present invention all belong within protection scope of the present invention.
