Description
Technical field
The present invention relates to gyratory crusher, relate in particular to a kind of control system and overload protection method thereof of gyratory crusher.
Background technology
Existing gyratory crusher automatic control system; Structure and operation logic are simple, and shortcoming is can not carry out the host work load to detect automatically and control, during disintegrating machine work; Main unit load changes greatly, and production power consumption, production efficiency and the dependability of disintegrating machine all had adverse influence.Patent: (application number: 201120360653.2) announced a kind of automatic control system of hydro cone-crusher, system is a core controller with PLC (Programmable Logic Controller programmable logic controller (PLC)) to automatic control system of hydrocone crusher.But the problem of its existence is: when disintegrating machine runs into hard thing overload, do not have overload protection arrangement, disintegrating machine is damaged; Simultaneously, do not dispose Long-distance Control and supervising device, influenced the operator disintegrating machine is carried out Long-distance Control, can't realize that people control is positioned at the purpose of many disintegrating machines of diverse location.The control system that present people thirst for a kind of novel gyratory crusher solves the problem in the reality.
Summary of the invention
To the deficiency of prior art, the purpose of this invention is to provide a kind of control system and overload protection method thereof of gyratory crusher.
The technical solution adopted for the present invention to solve the technical problems is:
The control system of gyratory crusher comprises remote monitor, on-site supervision device, PLC, frequency converter, gives ore deposit motor, magnetic valve, hydraulic system, gyratory crusher, motor, position transmitter, temperature transmitter, pressure transmitter, power transducer, overload protective device; PLC links to each other with remote monitor, on-site supervision device respectively; PLC and frequency converter, link to each other for ore deposit motor, gyratory crusher in order; PLC links to each other with magnetic valve, hydraulic system, gyratory crusher in order; Gyratory crusher links to each other with PLC through position transmitter, temperature transmitter respectively, and gyratory crusher links to each other with PLC through overload protective device, pressure transmitter; Motor links to each other with gyratory crusher, and motor links to each other with PLC through power transducer; Overload protective device comprises accumulator and overload check valve.
The overload protection method of the control system of gyratory crusher is: disintegrating machine runs into hard thing and when transshipping, the in-oil cylinder service load pressure of main shaft surpasses charging pressure of accumulator, and the overload one-way valve opens is in the instantaneous entering accumulator of fluid; Simultaneously, pressure transmitter detects the ANOMALOUS VARIATIONS of load pressure and signal is passed to PLC, and after PLC judged, the primer fluid pressing system was regulated automatically, and hard thing is discharged from disintegrating machine, discharge hard thing after disintegrating machine continue to recover normal operation.
The invention has the beneficial effects as follows that when disintegrating machine runs into hard thing and when transshipping, makes the unlikely damage of disintegrating machine, safe in utilization with protection equipment realized that simultaneously people's Long-distance Control is positioned at the purpose of many disintegrating machines of diverse location.
Description of drawings
Fig. 1 is the structural representation of the control system of gyratory crusher;
Fig. 2 is an overload protective device sketch map of the present invention.
The specific embodiment
Below in conjunction with the detailed embodiment of the present invention of accompanying drawing:
Like Fig. 1, shown in 2, the control system of gyratory crusher comprises remote monitor, on-site supervision device, PLC, frequency converter, gives ore deposit motor, magnetic valve, hydraulic system, gyratory crusher, motor, position transmitter, temperature transmitter, pressure transmitter, power transducer, overload protective device; PLC links to each other with remote monitor, on-site supervision device respectively; PLC and frequency converter, link to each other for ore deposit motor, gyratory crusher in order; PLC links to each other with magnetic valve, hydraulic system, gyratory crusher in order; Gyratory crusher links to each other with PLC through position transmitter, temperature transmitter respectively, and gyratory crusher links to each other with PLC through overload protective device, pressure transmitter; Motor links to each other with gyratory crusher, and motor links to each other with PLC through power transducer; Overload protective device comprises accumulator 1 and overload check valve 2.
The overload protection method of the control system of gyratory crusher is: disintegrating machine runs into hard thing and when transshipping, the in-oil cylinder service load pressure of main shaft surpasses accumulator 1 the blowing pressure, and overload check valve 2 is opened, in the instantaneous entering accumulator 1 of fluid; Simultaneously, pressure transmitter detects the ANOMALOUS VARIATIONS of load pressure and signal is passed to PLC, and after PLC judged, the primer fluid pressing system was regulated automatically, and hard thing is discharged from disintegrating machine, discharge hard thing after disintegrating machine continue to recover normal operation.
System is core controller with PLC; Remote monitor, on-site supervision device are as man-machine interface; Detect the gape of gyratory crusher, the temperature that temperature transmitter detects lubricating oil, the pressure that pressure transmitter detects lubricating oil, the power that power transducer detects drive motors through position transmitter; PLC uses the certain controlled quentity controlled variable of fuzzy control model output according to the data of gathering, and adjusts the size of adjusting gape to the ore deposit rotating speed of motor and through hydraulic system through frequency converter; It is invariable finally to reach main motor current, i.e. the stable control target of disintegrating machine live load.For realizing the enterprise production process automation, adopt remote monitor to carry out communication, so that the disintegrating machine duty is monitored and controlled, realized that people's Long-distance Control is positioned at the purpose of many disintegrating machines of diverse location at Control Room.
