Abstract
The invention relates to the technical field of belt conveying, in particular to a device for preventing slippage of a belt driven by a variable frequency motor. The device comprises a first patch mounted on a driving wheel of a belt conveyor, a first proximity switch mounted on one side out of the driving wheel, a second patch mounted on a driven wheel of the belt conveyor, a second proximity switch mounted on one side out of the driven wheel, and a PLC control system; the first proximity switch and the second proximity switch are electrically connected with the PLC control system; and the PLC control system detects a real-time pulse frequency P1t of the first proximity switch and a real-time pulse frequency P2t of the second proximity switch. The device realizes protection on belt slippage, protects the driving wheel driven by the variable frequency motor, and can realize perfect protection.
Description
Technical field
The present invention relates to belt tranmission techniques field, more particularly to a kind of belt slippage preventing frequency conversion motor from driving
Device.
Background technology
Rubber conveyer is the capital equipment of Mine haul, and the slipping protection of sealing-tape machine can be effectively prevented sealing-tape machine
After skidding, belt is rubbed even on fire.The sealing-tape machine that power frequency drives is constant because of its tape speed, the realization of its slipping protection
It is easier.What the implementation of slipping protection was commonly used at present has contact and contactless two kinds.Both slipping protections are all
It is based on carrying out under belt constant speed being adjusted by a certain constant speed, but the belt haulage that frequency conversion motor is driven
Machine, can report sipping fault by mistake after the adhesive tape speed of service declines.And the sealing-tape machine of actually frequency conversion drive in process of production should
More and more, there is presently no the device that frequency conversion adhesive tape slipping can be carried out with effective protection.
The defect that former construction exists：
In producing at present its operation principle of adhesive tape slipping measurement apparatus be all based on the actual speed to adhesive tape and adhesive tape
Normal speed be compared, when actual speed is less than normal speed certain value, slipping protection action simultaneously sends warning or jumps
Lock signal, but the normal speed of sealing-tape machine once sets the change that cannot be in operation, if drive for frequency conversion motor
Sealing-tape machine, will be mistakenly considered skidding after frequency descent tape prompt drop is low.At present slipping protection device open in sealing-tape machine
Period that is dynamic and being easiest to generation skidding during braking is not provided that slipping protection.
Content of the invention
The technical problem to be solved is：How a kind of frequency conversion to be provided and that not frequency conversion Motor drive is suitable for is anti-
Only belt slippage device.
The technical solution adopted in the present invention is：A kind of device preventing rubber conveyer belt slippage, including being arranged on
The first paster on the drivewheel of rubber conveyer, be arranged on the first proximity switch of the outer side of drivewheel, to be arranged on adhesive tape defeated
Send the second paster on the driven pulley of machine, the second proximity switch being arranged on the outer side of driven pulley, PLC control system, first connects
Nearly switch and the second proximity switch electrical connection PLC control system, in rotation process, the first paster periodicity turns over the to drivewheel
One proximity switch, the first proximity switch can produce pulse signal, and the second proximity switch is similar with the first proximity switch, and PLC controls
System detectio is to the real-time pulse frequency of the first proximity switchReal-time pulse frequency with the second proximity switchIf,
In arbitrary continuation 5 seconds,Minima be less than 5% belt non-slip, if in arbitrary continuation 5
In seconds,Minima be more than or equal to 5% and be less than 12% belt slippage but serious, PLC is controlled
System processed sends alarm signal, if in arbitrary continuation 5 seconds,Minima be more than or equal to
12% belt slippage is serious, and PLC control system sends stopping signal to the motor driving drivewheel to rotate, and sends alarm signal
Number.In belt startup stage, or in conversion process, due to the tension force effect of belt, the short time occursWithNo
The larger situation of difference, this it is not necessarily the case that skid, generally require delay judged again within several seconds, so the present invention lead to
Cross in observation arbitrary continuation 5 secondsWithDifference, just can show whether belt skids, if need promptly to stop
Machine.
The invention has the beneficial effects as follows：Present invention achieves the protection to belt slippage, protection adjustable frequency motor drive
Drivewheel, can realize perfect protection.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is drivewheel structural representation；
Wherein, the 1, first paster, 2, drivewheel, 3, belt, the 4, second paster, 5, driven pulley, the 6, first proximity switch.
Specific embodiment
Present configuration is to skid in belt transmit process using existing to solve the drivewheel of frequency conversion motor drive
Technological means cannot prepare the problem weighed, the speed due to drivewheel can often change, and occurs to skid and often send out
In the stage that life changes in speed, because belt has elasticity, deliver power to driven pulley from drivewheel and have certain prolonging
Phase is so that existing testing equipment cannot meet the requirement that detection is skidded late.
As depicted in figs. 1 and 2, the present invention installs paster and proximity switch on drivewheel and driven pulley, due to drivewheel
With driven pulley in rotation process, paster, can pass through thus proximity switch can produce a pulse periodically close proximity to switch
The frequency of this pulse can accurately determine the speed of wheel.The pulse frequency that PLC control system sends to two proximity switches is entered
Row is processed, and PLC control system detects the real-time pulse frequency of the first proximity switchReal-time pulse with the second proximity switch
FrequencyIf, in arbitrary continuation 5 seconds,Minima be less than 5% belt non-slip,
If in arbitrary continuation 5 seconds,Minima be more than or equal to 5% be less than 12% belt slippage
But not serious, PLC control system sends alarm signal, if in arbitrary continuation 5 seconds,
Minima be more than or equal to that 12% belt slippage is serious, PLC control system sends shutdown letter to the motor driving drivewheel to rotate
Number, and send alarm signal.
