Description
Technical field
The utility model relates to a kind of belt tearing checking system, is specifically related to a kind of belt tearing image identification system.
Background technology
Ribbon conveyer is widely used in the fields such as harbour, mine, steel mill, power plant.Load-transfer device is the important component part of ribbon conveyer, and load-transfer device mainly contains plain sail core belt, syntheticfibres core belt, steel rope core belt etc.Along with band conveyor is towards high speed, the future development of extensive, extra long distance, high spud angle, steel rope core belt is also more and more widely used.Because steel rope core belt price is more expensive, and be often applied in the occasion of high speed, long distance, thus determine this belt once there is longitudinal tear, its loss caused will be very huge.
Belt longitudinal tear accident happens occasionally, and according to Australia's statistics, longitudinal tear possibility occurs a belt in its life cycle about has 20%.Be worth the load-transfer device of even tens million of unit of millions of unit, once there is longitudinal tear accident, all will damage within very short time, cause huge economic loss.Namely allow to repair, also need suitable manpower and time, impact is greatly produced on normal production.The use amount of China Leather belt conveyor was increasing in recent years, and the increasing extent of its application is wide, used the accident of factories and miness generation longitudinal tear also more and more frequent.Although there are many achievements in research, the whole world does not still have a kind of ideal up to now, the mature equipment of the effective detection longitudinal tear that can promote on a large scale.
The belt protecting longitudinal rupture of at present both at home and abroad research and monitoring device form and of a great variety.But be summed up and mainly contain following three types:
Embedding inlay technique, this method normally adopts in belt or belt surface buries the methods such as plain conductor, coil, magnetic or certain conduction, permeability magnetic material in advance underground, by the integraty of pre-buried thing in monitoring belt, check implement judges whether belt longitudinal tear occurs.It has significant limitation in actual applications: 1, this type of fender guard is that complex process, cost are high; 2, the detection of a large amount of belt of installation and operation cannot be applied to; 3 but move due to the long-time continuous of belt, inevitably produce the sustained stress of rolling cut, plain conductor, coil or other pre-buried materials is made to be worn and torn and rupture, thus cause the erroneous judgement of detection, 4, because belt is embedded in detection material, the maintenance of belt user is had higher requirement.
Contact method, this method is not changed belt usually, is carried out the situation of perception belt by the contact of sensing device and belt.More sensing device is used to be carrying roller in actual applications.Wherein, a kind of be carrying roller directly and belt contacts thus the physical quantity of the operation of perception belt, as the running velocity, tension force, pressure etc. of belt.During due to longitudinal tear occurring, inconsistent when the tension force of belt (laterally, longitudinally), pressure, speed or other physical quantitys normally can work with belt, indirectly judge belt generation longitudinal tear thus.The shortcoming of this method is that reliability is not high.Another kind is the transmitter-receiver device using carrying roller as detection signal, being produced and receives the signals such as electricity, magnetic, light, sound, judging whether belt longitudinal tear occurs by analyzing this signal by the device be arranged on carrying roller.But due to carrying roller in belt runs always with belt contacts, wearing and tearing are very large, and being easy to cause as sensing device is that carrying roller damages and malfunctioning.
Visit dew method, adopt and visit dew method as longitudinal tear warning device, its core concept is after there is longitudinal tear, has material to stretch out belt crack or material leakage in the tear place of belt.Thereby produce rod type detector, string of a musical instrument formula device, leak material detector etc.Rod type detector is that a rod or pipe bent are become trough idler shape, is arranged between the impact idler below flute profile load-transfer device and forms.Like this, if any the material piercing through load-transfer device, this material will stir the deflection of flute profile rod, force limit switch or load transducer action, belt conveyer is shut down.String of a musical instrument formula device and bar type detector similar, this device is by nylon wire as probe, and be placed between impact idler and fit through aperture and flute profile band lower surface, one end of line fills a spring retainer switch.When the material piercing through load-transfer device stumbles this line, line is broken or tension force increase, all can make limit switch action.Leak material detector to be made up of pallet, fulcrum, bob-weight and switch etc.After load-transfer device is by longitudinal tear, the material on load-transfer device leaks in pallet by breach, and the weight of material overcomes the weight of bob-weight, makes whole device around fulcrum, forces limit switch action.But be broaden with breach after belt longitudinal tear owing to visiting dew method, thus cause material to stretch out or based on the principle revealed, so once after belt tearing, if belt does not have breach or breach wide not, material would not occur and stretch out belt crack or leakage, then this method cannot detect.After load-transfer device is by longitudinal tear, only have load-transfer device has material and the breach of load-transfer device is enough to make material from leakage time, this device just can work, otherwise is just of little use.
In sum, still do not have ideal so far, effectively can prevent the detection method of longitudinal tear and be applied to the device of practice.
