Description
Technical field
The present invention relates to hydro cone-crusher technical field, particularly a kind of gyratory crusher with online temp monitoring function.
Background technology
Large hydraulic gyratory crusher has the features such as the ratio of reduction is large, output is high, consume energy less, product granularity is even, in the broken production operation in mine, obtains extensive use.Due to the restriction of structure, traditional temperature, pressure sensor cannot be arranged on some important mechanical locations (the narrow space place such as engagement place as gear), can not carry out data monitoring, be unfavorable for the service life of extension device to some important test points.
Summary of the invention
The object of this invention is to provide a kind of gyratory crusher with online temp monitoring function, utilize fiber Bragg grating (FBG) demodulator, temperature sensor, the mechanical location of detection is rationally set, online temperature detection is carried out to the groundwork element of gyratory crusher, reaches the object extending gyratory crusher service life.
The object of the invention is to be realized by following technical proposals:
The gyratory crusher with online temp monitoring function of the present invention, comprise PLC system, it is characterized in that described PLC system respectively with temperature alarm, pressure alarm, fiber Bragg grating (FBG) demodulator is connected, this fiber Bragg grating (FBG) demodulator by optical fiber respectively with the bearing shell lubricating oil temperature sensor and the bearing shell lubricant pressure sensor that are arranged on gyratory crusher spindle bearing bush side, be arranged on the axle top lubricating oil temperature sensor of gyratory crusher spindle top, the power transmission shaft lubricating oil temperature sensor be arranged on drive shaft of cone crusher is connected with power transmission shaft lubricant pressure sensor,
Set temperature trace routine and pressure detecting program in described PLC system.
Described optical fiber is arranged in titanium alloy guide passage pipe, this titanium alloy guide passage pipe abuts on gyratory crusher main shaft and drive shaft of cone crusher respectively, and described bearing shell lubricating oil temperature sensor, axle top lubricating oil temperature sensor, power transmission shaft lubricating oil temperature sensor and power transmission shaft lubricant pressure sensor difference docile is on the inwall of described titanium alloy guide passage pipe.
The diameter of described titanium alloy guide passage pipe is 5mm.
According to version and the test request of disintegrating machine, the present invention is to the measurement carrying out oil temperature and pressure near spindle bearing bush, and spindle top carries out lube temperature measure, and power transmission shaft carries out the measurement of oil temperature and pressure.Guide passage tubing matter takes titanium alloy.The signal collected carries out demodulation through fiber Bragg grating (FBG) demodulator, and the data of demodulation result are transferred to PLC system, to the data analysis process of demodulation, obtains the parameter of disintegrating machine temperature parameter and pressure.The change of Real-time Monitoring Data, when the numerical value of temperature and pressure exceedes the threshold value of setting, carries out alert process, for disintegrating machine provides monitoring and protecting.
The invention has the beneficial effects as follows, can temperature, the force value of each important test point of on line real-time monitoring, effectively can prevent disintegrating machine Yin Wendu, hypertonia and the damage caused.When the temperature varies, can overhaul by schedule ahead, extend the service life of disintegrating machine.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention.
Fig. 2 is sensor arrangement schematic diagram of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2, the gyratory crusher with online temp monitoring function of the present invention, comprise PLC system, it is characterized in that described PLC system respectively with temperature alarm, pressure alarm, fiber Bragg grating (FBG) demodulator is connected, this fiber Bragg grating (FBG) demodulator by optical fiber 2 respectively with the bearing shell lubricating oil temperature sensor 4 and the bearing shell lubricant pressure sensor 5 that are arranged on gyratory crusher main shaft 1 bearing shell side, be arranged on the axle top lubricating oil temperature sensor at gyratory crusher main shaft 1 top, the power transmission shaft lubricating oil temperature sensor 6 be arranged on drive shaft of cone crusher 8 is connected with power transmission shaft lubricant pressure sensor 7,
Set temperature trace routine and pressure detecting program in described PLC system.
Described optical fiber 2 is arranged in titanium alloy guide passage pipe 3, this titanium alloy guide passage pipe 3 abuts on gyratory crusher main shaft 1 and drive shaft of cone crusher 8 respectively, and described bearing shell lubricating oil temperature sensor 4, axle top lubricating oil temperature sensor (not shown), power transmission shaft lubricating oil temperature sensor 6 and power transmission shaft lubricant pressure sensor 7 difference docile is at the inwall of described titanium alloy guide passage pipe 3.
The diameter of described titanium alloy guide passage pipe is 5mm.
According to version and the test request of disintegrating machine, intend the measuring technology scheme taked as shown in the figure, to the measurement carrying out oil temperature and pressure near spindle bearing bush, spindle top carries out lube temperature measure, and power transmission shaft carries out the measurement of oil temperature and pressure.Guide passage tubing matter is intended taking titanium alloy, and the diameter of titanium pipe is 5mm, and the structural design of titanium pipe is intended taking form shown in figure, the inwall of fiber-optical grating temperature sensor docile titanium pipe, fixes pressure sensor by designing special device.The signal collected carries out demodulation through fiber Bragg grating (FBG) demodulator, and the data of result demodulation are transferred to computer, and computer, to the data analysis process of demodulation, obtains the parameter of disintegrating machine temperature parameter and pressure.The change of Real-time Monitoring Data, when the numerical value of temperature and pressure exceedes the threshold value of setting, carries out alert process, for disintegrating machine provides monitoring and protecting.
