It is that roller bearing screening machine electric motor for rolling way is monitored and controlled, according to the long-range start and stop electric motor for rolling way of the needs of coal handling system.In reality
In operation, due to being connected together by elastic dowel pin shaft coupling between the speed reducer and screen axis of electric motor for rolling way, it may appear that screen axis
It is blocked by big coal cinder, electric motor for rolling way also be easy to cause the pin fracture of shaft coupling in rotation, so as to cause causing roller-way electric
Motivation transfers the case where screen axis does not turn, if such case cannot be run in time or service personnel has found, it is easy to cause to roll
Axis screening machine chute blockage.Worker's cleaning chute blockage labor intensity is very high, very arduous, and the additional coal dust pollution flown upward seriously affects a
The physical and mental health of people.
Utility model content
The purpose of this utility model is to provide a kind of roller bearing screening machine screen axis rotational speed monitor system, it is ensured that roller bearing screening machine is steady
Smooth and coal handling system stable operation that is qualitative and ensureing production task, by the screen axis rotation speed monitoring to roller bearing screening machine,
Control system finds that electric motor for rolling way turns such case that screen axis does not turn in time, is automatically stopped electric motor for rolling way, reduces chute blockage thing
Part occurs.
To achieve the above object, the technical solution of the utility model is：
A kind of roller bearing screening machine screen axis rotational speed monitor system, it is characterized in that including Monitor Computer Control System, PLC controller,
Non-contact speed monitoring switch and roller bearing screening machine ontology, weld one in the right side shield of the roller bearing screening machine ontology
Angle bar is for fixing non-contact speed monitoring switch；Being welded on being exposed at roller bearing screening machine babinet outer portion screen axis has screw, spiral shell
The distance between silk and the pulse detection probe segment of non-contact speed monitoring switch are 1-2 centimetres, the ipc monitor
It is connected by Ethernet between system and PLC controller, reads the data in PLC controller in real time, pass through man-machine interface pair
Data in PLC controller carry out Dynamic Announce and control, the roller bearing screening machine screen axis stall that Monitor Computer Control System will receive
The pop-up in time of alarm signal dynamic, reminds operations staff, operations staff to take next step action according to actual conditions.
The characteristics of the utility model, is as follows：
(1) by using this system, main control room operations staff can monitor the overall operation feelings of roller bearing screening machine in real time
Condition, discovery and handling failure, guaranteeing role is played to the stable operation of entire coal handling system in time.
(2) the timely discovering device failure of main control room operations staff and corresponding disposition work is made since this system can allow
Make, reduces the case where roller bearing screening machine generates chute blockage, significantly reduce the labor intensity of operations staff on the spot, reduce dust
Soakage, certain protective effect is played to the physical and mental health of worker.
(3) success of the system puts into operation lays a solid foundation for personnel reduction and enlargement from now on.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the work flow diagram of the utility model.
Specific implementation mode
The structure and operation principle of the utility model are described in detail below according to attached drawing
Referring to Fig. 1, this system includes Monitor Computer Control System 1, PLC controller 2, non-contact speed monitoring switch 3 and rolling
Axis screening machine ontology 4；Small-sized integrated type can be selected in the PLC controller 2, wherein embedded computer system is carried,
It is provided simultaneously with corresponding communication interface, such as has the function of ethernet communication.It is protected on the right side of the roller bearing screening machine ontology 4
An angle bar 6 is welded on cover, for fixing non-contact speed monitoring switch 3；The non-contact speed monitoring switch 3 has one
Body feature has pulse detection, comparator processor and output switching amplifier, operation principle in same shell：Switch is pre-
A signal frequency is first set to handle to comparator, and the movement of testee also generates a frequency of oscillation and enters and compares
Device, when the frequency of oscillation of testee is less than speed switch setpoint frequency, switch is in an open state；When the oscillation of testee
When frequency is more than speed switch setpoint frequency, switch as closed state；In order to make the movement of testee roller bearing screening machine screen axis 5
A frequency of oscillation is generated, need to do is exactly the screw 7 that is welded on being exposed at roller bearing screening machine babinet outer portion screen axis 5, spiral shell
The distance between silk 7 and the pulse detection probe segment of non-contact speed monitoring switch 3 are 1 to 2 centimetre, such roller bearing screening
5 per revolution of machine screen axis, non-contact speed monitoring switch 3 can detect primary oscillation.
Non-contact 3 monitoring frequency of speed monitoring switch is set as 0 in real work, as long as roller bearing screening machine screen axis 5 stops
Rotation stop is dynamic, and non-contact speed monitoring switch 3 is just in an open state；The PLC controller 2 receives non-contact speed monitoring and opens
It closes 3 and is transmitted through the opening state signal come, by programming in logic, export 5 stall alert signal of roller bearing screening machine screen axis, while automatic
9 halt instruction of runout table motor；It is connected by Ethernet between the Monitor Computer Control System 1 and PLC controller 2,
The data in PLC controller 2 are read in real time, and Dynamic Announce and control are carried out to the data in PLC controller 2 by man-machine interface
System, Monitor Computer Control System 1 can pop up the 5 stall alert signal dynamics of roller bearing screening machine screen axis received in time, remind operation
Personnel, operations staff take next step action according to actual conditions.
The course of work of this system is：Referring to Fig. 1, Fig. 2, non-contact speed monitoring switch 3 transmits switch state signal
Into PLC controller 2, signal value is " 1 ", indicates that switch is closed, and signal value is " 0 ", indicates that switch is opened；PLC controller 2 will
Switch state signal value and the run signal value of electric motor for rolling way 9 do logical process, i.e., when switch state signal value is " 0 ", together
When electric motor for rolling way 9 run signal value when being " 1 ", 5 stall alert signal of output roller bearing screening machine screen axis and electric motor for rolling way 9
Halt instruction.Monitor Computer Control System 1 does corresponding Dynamic Announce, and operations staff, which makes, stops higher level equipment work.
The utility model by advanced Computer Control Technology, industrial control technology, non-contact speed monitoring technology melt for
One.The system is made of host computer+PLC programmable logic controller (PLC)s+non-contact speed monitoring switch, has preferable extension
Ability and upgrading ability.The utility model is the upgrading made to the monitoring and controlling of roller bearing screening machine, and operations staff is made to exist
I.e. it can be seen that the actual rotation operating condition of the screen axis of roller picker extension set, whole to roller bearing screening machine on the computer of remote control room
The operating condition of body has more detailed understanding, reduces the failure rate of roller bearing screening machine, ensures the stable operation of whole equipment.
