Description
The utility model relates to a kind of belt protection device, particularly a kind of contactless electronic belt protection device.
Mostly be the mechanical contact formula at belt operating fender guard; for example belt slip-skid prevention, anti-deviation device, wherein the sideslip fender guard of belt is the mechanical contact formula, behind the belt deviation; the belt of displacement promotes mechanical lever and makes mechanical electrical contact closure, sends guard signal.The mechanical lever part that its belt promotes is owing to often contact with belt; be subjected to belt do not stop the friction; damage easily; simultaneously belt is worn; mechanical electrical contact is also easily because of corrosion and other reason bad contact; cause the fender guard life-span short, protection can not correc operation behind the belt deviation, can't play a protective role.The slipping protection device of belt has two kinds; a kind of tachogenerator formula; the wheel of adorning with tachogenerator directly and the belt friction; driving tachogenerator rotates to measure belt speed; its advantage is directly to survey the speed of belt; shortcoming is skidding relatively between belt and the tachogenerator wheel often to occur, and make test the speed inaccurate.Another kind is the rotating speed that electromagnetic induction or photoelectricity transformation principle are directly surveyed the belt follower, thereby determines belt speed, and this is a kind of method of indirect survey belt belt speed, and when skidding between belt and the follower, the speed that records is inaccurate.
Order of the present utility model provides a kind of contactless electronic belt protection device, and it can not have the operation of wearing and tearing ground, and the life-span is long; Measure accurately and reliably, can the operation of belt be played a protective role.
The purpose of this utility model realizes by following technical scheme.This contactless electronic belt protection device comprises magnet steel, sampling coil, is divided into some equal portions on the belt total length, at each Along ent place, in the thickness of belt direction magnet steel is housed; Below the route of magnet steel with the belt operation, be equipped with and the discontiguous fixing sampling coil of belt, this sampling coil and signal processor unit are done and are electrically connected.Need detect belt operation conditions place in belt one side column is housed, sample line coil support and described signal processor unit are housed on column, described sampling coil is housed on the sample line coil support.Described sampling coil is the slip-skid prevention coil, and it is centered close on the projection line of magnet steel centre of form running route.Described sampling coil is anti-deviation coil, comprise light sideslip coil and heavy sideslip coil, the outer rim of two light sideslip coils is at a distance of a distance, and magnet steel is over against the middle empty position of two adjacent outer rims of winding of light sideslip coil, and two heavy sideslip coils are symmetrically located at two light sideslip coil outsides.The utility model adopts electromagnetic induction principle; magnet steel is embedded in the belt; respond to this fixing sampling coil by the magnet steel of operation; as Fig. 1, carry out signal sampling by the sampling coil, send signal to signal processor unit and carry out signal comparison and signal judgement; outlet is handled again; send the corresponding protection signal, this off-square operation is corrected or handled to the instruction protection mechanism, with the protection belt.This electronics noncontact measurement is measured accurately and reliably than above-mentioned alternate manner, owing to the sampling coil does not contact with belt and magnet steel, so do not have the machinery wearing and tearing, long service life and the difficult operating troubles that takes place.
Do concrete introduction below in conjunction with accompanying drawing with embodiment.
Fig. 1 is a signal conditioning block diagram of the present utility model,
Fig. 2 is the vertical arrangement plans of components and parts of the present utility model,
Fig. 3,4 is the A-A cutaway view Amplified image among Fig. 2, shows the lateral arrangement of components and parts.
Code name among the figure: 1 belt pulley, 2 sampling coils, 3 signal processor unit, 4 magnet steel, 5 belts, 6 belt pulleys, 7 sample line coil supports, 8 columns
Embodiment 1.The embodiment that is used for the slipping of the belt protection for the utility model.As Fig. 2,3, belt 5 is around belt pulley 1, on 6, at the length direction of belt 5 every the outward flange 1.5cm place of the distance L (about 20 meters) that equates at distance belt 5,4 some of magnet steel are placed in middle part along belt 5 thickness directions, at correct position vertical columns 8 (available belt support replaces) along belt 5 length directions, fixed signal processing equipment 3 and sample line coil support 7 on column 8, fixed sample coil 2 on the sample line coil support 7, sampling coil 2 is positioned at the below of magnet steel 4 running routies, and sampling coil 2 is done with signal processor unit 3 and is electrically connected (not shown).Belt 5 runnings, first block of magnet steel 4 in being contained in belt 5 is from sampling coil 2 tops when inswept, magnetic force line cutting sampling coil 2, thereby make its voltage of inducting, its value is about 1-10MV, this millivolt level signal is picked up counting after relatively judging affirmation by the sampling of the sample circuit of signal processor unit 3.To second block of magnet steel, 4 inswept sampling coils 2, produce second sampled signal, this signal is received by signal processor unit 3 again, stops timing for the first time after judging, and beginning timing for the second time utilizes primary timing time simultaneously, judges whether belt skids.Because of the normal operation belt speed constant; and the constant distance between two blocks of magnet steel; so the time between the sub-sampled signal should be constant; between institute's timing if slipping of the belt then is described greater than this constant; length according to this time also can accurately calculate the operating speed of belt reality and the degree of skidding; thereby provide slipping protection signal accurately by demand, make the fender guard action.
As Fig. 2,4, be the scheme drawing of anti-deviation fender guard, different with the slip-skid prevention fender guard is the sampling coil, it comprises two windings of light sideslip sampling coil 2A and two windings of heavy sideslip sampling coil 2B.Nearest two outward flanges of two windings of light sideslip sampling coil 2A are at a distance of 8-12cm, and two windings of heavy sideslip sampling coil 2B are symmetrically located at two windings outsides of light sideslip sampling coil 2A and place the center in-line of four windings.During sideslip, the magnet steel 4 that is contained on the belt 5 does not pass the outside of two windings of sideslip sampling coil 2A belt 5 on the lenient side, and magnetic force line cutting is less than coil winding, and sampling coil 2A, 2B no signal are sent.Be contained in magnet steel 4 one the top process in four windings of sideslip coil 2A or heavy sideslip coil 2B on the lenient side in the belt 5 during belt 5 sideslips; its magnetic force line cutting sampling coil winding; thereby make its voltage of inducting; its value is about 1-10MV; the signal of this millivolt level is the sampling section sampling of processing equipment 4 by letter; after relatively judgement is confirmed to be light sideslip or heavy sideslip, send corresponding sideslip breakdown signal, belt is protected.This sideslip breakdown signal can be contact switch signal or noncontacting switch signal.
In sum; adopt contactless electronic belt protection device of the present utility model; owing to adopted signal propulsion source magnet steel is embedded in specific process in the belt; make the sampling coil of fender guard and belt under discontiguous situation; the running velocity and the offset signals of belt have accurately been collected; after electronic signal processing apparatus is handled; send guard signal; the service life and the reliability of slipping of the belt and sideslip fender guard have greatly been improved; and can not cause any damage, thereby can be widely used belt.The utility model is suitable for the protection of each transmission, travelling belt and uses.
