Silence signal, the not alarm of described alarm module is exported to alarm module；If gained umber of pulse is less than predetermined pulse number, than
Relatively device exports second electrical level signal to PLC control module, and PLC control module triggers signal, described warning to alarm module output
Module alarm.
The supervising device simple in construction of this heating furnace drum drive mechanism, Magnetic Sensor and magnet steel within the detection stipulated time
During the umber of pulse that phase separation produces, it is i.e. to have detected all numbers that heating furnace drum drive mechanism is rotated in the stipulated time, or
Say the dynamic rotary speed that have detected heating furnace drum drive mechanism.Produced by Magnetic Sensor in the detection stipulated time and magnet steel phase separation
Raw umber of pulse, and make comparisons with predetermined pulse number, thus learn whether this heating furnace drum drive mechanism runs well, thus
Can effectively predict danger, alarm can be sent in time for danger, thus make corresponding remedial measure, by the damage control
In little scope.
Further, described heating furnace drum drive mechanism has on three power transmission shafts and be provided with magnet steel, and these three
Driven shaft is uniformly distributed on described heating furnace drum drive mechanism.So can detect heating furnace drum drive machine more accurately
All numbers that structure was rotated in the stipulated time or dynamic rotary speed, consequently facilitating the supervising device of this heating furnace drum drive mechanism is more
Accurately heating furnace drum drive mechanism is monitored.
Preferably, described magnet steel is arranged on the driven shaft of described heating furnace drum drive mechanism.Magnet steel is arranged at from
On moving axis, the setting of Magnetic Sensor can be facilitated, in order to by Magnetic Sensor with magnet steel just to setting.
Further, described PLC control module, enumerator and comparator are integrated on same circuit board.Which save sky
Between, also reduce the volume of the supervising device of this heating furnace drum drive mechanism simultaneously.
Preferably, described Magnetic Sensor is one of Hall element, magnetoresistive transducer or tongue tube.Hall element, magnetic
Resistance sensor and tongue tube price all ratios are relatively low, have again preferable Detection results simultaneously.
Further, also include that warning mask switch, described warning mask switch are connected to described enumerator and comparator
Between.In process of production, replacing bearing, cylinder can be run into unavoidably or safeguard the situation of other zero devices, this hour counter
Obtained umber of pulse there will be exception, and now staff disconnects warning mask switch, and comparator will can not receive enumerator institute
The pulse signal of input, PLC controls alarm module and does not send alarm.
Additional aspect of the present utility model and advantage will part be given in the following description, and part will be from explained below
In become obvious, or recognized by practice of the present utility model.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage are from combining general the accompanying drawings below description to embodiment
Become obvious and easy to understand, wherein:
Fig. 1 is structured flowchart of the present utility model；
Fig. 2 is that this utility model uses schematic diagram.
Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng
It is exemplary for examining the embodiment that accompanying drawing describes, and is only used for explaining this utility model, and it is not intended that to of the present utility model
Limit.
In description of the present utility model, unless otherwise prescribed and limit, it should be noted that term " is installed ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be mechanically connected or electrically connect, it is also possible to be the company of two element internals
Logical, can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, for the ordinary skill in the art, can
To understand the concrete meaning of above-mentioned term as the case may be.
The supervising device of a kind of heating furnace drum drive mechanism as depicted in figs. 1 and 2, including PLC control module, counting
Device, comparator, Magnetic Sensor and alarm module, at least power transmission shaft of heating furnace drum drive mechanism is provided with can be with magnetic
Sensor just to magnet steel.In the present embodiment, Magnetic Sensor is one of Hall element, magnetoresistive transducer or tongue tube, and PLC is controlled
Molding block, enumerator and comparator are integrated on same circuit board.
Magnetic Sensor outfan linkage counter input, Magnetic Sensor and magnet steel position relative to time, produce a pulse
And it being sent to enumerator, the outfan of enumerator is connected with the first input end of comparator, and the second input of comparator connects
The setting output port of PLC control module, comparator output terminal connects PLC control module input, and PLC control module exports
End connects alarm module input, if gained umber of pulse is more than or equal to predetermined pulse number, comparator is defeated to PLC control module
Going out the first level signal, PLC control module exports silence signal, alarm module not alarm to alarm module；If gained
Umber of pulse is less than predetermined pulse number, and comparator exports second electrical level signal to PLC control module, and PLC control module is to warning mould
Block output triggers signal, alarm module alarm.
Heating furnace drum drive mechanism is checked by staff according to alarm, checks whether it is axle or chain appearance event
Barrier, or whether there is other fault, thus fault is got rid of, loss is reduced to minimum.Treat that staff is by event
After barrier is got rid of, or after the supervising device of this heating furnace drum drive mechanism restarts, enumerator is entered by PLC control module
Row resets.
As the preferred version of the present embodiment, heating furnace drum drive mechanism has on three power transmission shafts and be provided with magnetic
Steel, and these three power transmission shafts are uniformly distributed on heating furnace drum drive mechanism, for the ease of installing, are preferably installed on by magnet steel
On the driven shaft of power transmission shaft.
In process of production, can run into unavoidably and change bearing, cylinder or safeguard the situation of other zero devices, at this moment count
Umber of pulse obtained by device there will be exception, and alarm will send alarm.And in process of production, if alarm sends police
Report imply that the problem that there occurs than more serious, it will convenes many personnel to come together to solve.Therefore if in maintenance process
In and send alarm, which results in the erroneous judgement of warning, bigger waste of human resource can be caused.
Therefore to prevent this erroneous judgement from producing, the supervising device of this heating furnace drum drive mechanism also includes shielding of reporting to the police
Switch, warning mask switch is connected between enumerator and comparator.When heating furnace drum drive mechanism is being entered by staff
When row is safeguarded, disconnecting warning mask switch, comparator will can not receive the pulse signal that enumerator is inputted, and PLC controls
Alarm module does not send alarm.
In another embodiment, the output port of comparator is directly connected to the input of alarm module, and comparator is defeated
The level signal gone out does not inputs PLC control module, but directly controls whether alarm module reports to the police.
The setting of Magnetic Sensor for convenience, magnet steel is arranged on the driven shaft of heating furnace drum drive mechanism.
