Technical Field
The utility model belongs to the technical field of the torpedo hot metal mixer car state monitoring, more specifically says, relates to a torpedo hot metal mixer car tilting mechanism intelligent monitoring system.
Background
The mixer car is a special device for transporting molten iron smelted by a blast furnace to a steel plant pouring station, and is a main mode for transporting the molten iron of steel enterprises. The tilting mechanism is used as a core component for pouring the molten iron in the ladle body of the mixer car, the state of the tilting mechanism directly influences whether the mixer car can pour the molten iron into the ladle safely and smoothly, and the safe operation of the tilting mechanism is the key for realizing the steelmaking production of the converter.

And the operation environment of the iron mixing vehicle is relatively severe, when the iron is poured at the station of the steel plant pouring station, the iron mixing vehicle cannot enter the vehicle for testing, and the daily spot inspection operation can only be used for carrying out appearance inspection on the tilting mechanism, so that the equipment fault cannot be judged in advance, the dynamic operation state of the equipment is difficult to master, and the maintenance cost after the fault is high.
On the other hand, the tilting equipment of the torpedo hot metal mixer car is greatly influenced by high temperature, dust, vibration and the like, and the common faults of the tilting system of the torpedo hot metal mixer car and the influence of the common faults on the tilting operation of the torpedo hot metal mixer car are as follows: (1) The main bearing lubricating system and the auxiliary bearing lubricating system are in failure, so that the friction coefficient is increased, the load of the tilting motor is further increased, and the hidden trouble of overload burning loss of the tilting motor exists. (2) The brake can not be opened, the abnormal abrasion of the brake disc is aggravated, and meanwhile, the resistance of the tilting motor can also be increased. And (3) the motor and the reduction gearbox of the tilting mechanism have faults. Once various faults occur in the process of pouring molten iron, the tank body cannot rotate reversely to stop the operation of pouring the molten iron, so that the production accident of molten iron overflow can occur, and serious safety accidents and huge economic losses are brought to surrounding equipment and operators.
In recent years, with the concern of the country on the safety of special metallurgical equipment, some large-scale steel enterprises pay more attention to the management and use of the mixer cars, and through search, chinese patent CN 2018110604260 has an application date of 2018, 9 and 12, and the invention and creation names are: a control method of a torpedo type torpedo hot metal mixer car tilting band-type brake is disclosed, wherein a control program of the application is composed of functional blocks TYCC 01-TYCC 07; wherein: the functional block TYCC01 forms "the functional block for" the absolute value, and functional block TYCC02 and functional block TYCC04 are "numerical value comparison" functional block, and functional block TYCC03 and functional block TYCC05 are "impulse generator" functional block, and functional block TYCC06 is "or" gate, and functional block TYCC07 is "and" gate. This case makes the band-type brake be in the electrified state all the time through monitoring tilting motor moment of torsion variation condition, constantly adjusts, makes the tilting band-type brake also can realize the pulse type and fascinate under the bad condition of butt joint plug contact through this technical scheme. However, the scheme is only used for monitoring the connection state of the quick-connection socket and the plug of the work site, and cannot monitor the running states of a tilting system motor, a reduction gearbox, a main bearing, an auxiliary bearing and the like.
As another example, chinese patent No.: CN 2018106857844, the application date is: 6, 28 months in 2018, the patent names of the invention are: the application comprises a tilting device detection device, a detection control and data processing device, a car number reading device, a display screen, a 3G signal sending device and a 3G network receiving and data processing server, and judges the running state of the tilting device by detecting the working current of a motor, a brake and an oil pump of the tilting device of the torpedo car. However, the vibration, which is a main parameter for monitoring the state of the device, is not referred to in this case, and it is impossible to precisely analyze the faults of the motor, the bearing of the reduction gear box, the gear, and the like by monitoring only the current.
