Hall element 224 changes for detecting Hall voltage with the variation of magnetic field strength, and magnetic field is stronger, and voltage is higher,
When scraper plate passes through the first hall sensor 22, the second hall sensor 23, changes of magnetic field caused by scraper plate, so that the first permanent magnetism
Changes of magnetic field between body 221, the second permanent magnet 222, Hall element 224 export a voltage signal.Flat ring in chain and
The relatively caused changes of magnetic field of vertical ring is too small, and therefore, Hall element 224 cannot export the electricity for distinguishing flat ring and vertical ring in chain
Buckling cannot also identify the flat ring in chain and vertical ring.
In present embodiment, chain 80, right side chain 90 are respectively by the first hall sensor 22, the on the left of drag conveyor
Two hall sensors 23 detect, and first permanent magnet 221, second is forever in the first hall sensor 22 or the second hall sensor 23
The end polarity that magnet 222 is oppositely arranged between the first permanent magnet 221, the second permanent magnet 222 on the contrary, just can form complete
Distribution of Magnetic Field, the center between the first permanent magnet 221, the second permanent magnet 222 is arranged in Hall element 224, in left side chain
The position of item 80 and the center of right side chain 90 lower section has been respectively formed complete Distribution of Magnetic Field, detects and fills with chain rupture in the prior art
It sets and compares, magnetic field strength is high, and flat ring and vertical ring are since position, angle are different, and corresponding changes of magnetic field intensity is different, so that Hall
Element 224 can export different voltage signals, also set up magnetic conductive board 225 between the upper chain and lower chain of the same side chain, lead
Magnetic sheet 225 can shield interference of the chain to magnetic field, guarantee to the flat ring of downlink section chain and effective identification of vertical ring, for example,
Previous time point, upper chain are exactly flat ring, and lower chain is vertical ring, the latter time point, the exactly vertical ring of upper chain, lower chain
Item is flat ring, in this way, changes of magnetic field caused by the summation of former and later two time points, upper chain and lower chain is exactly like, is caused
The voltage signal that Hall element 224 exports is the same, and in this case, flat ring and vertical ring just cannot be distinguished from, and be based on above-mentioned set
Meter, scraper plate can only be detected in the prior art by solving, and detection accuracy is low, the technical bottleneck of poor reliability, so that drag conveyor
Chain rupture identification precision and reliability improve a height.
Following present the voltage for a Hall element 224 for using oscillograph to detect in a specific embodiment is defeated
It is worth out, according to the output of oscillograph as a result, the voltage value for the vertical ring that Hall element 224 exports is 3.0V, the voltage value of flat ring is
2.7V, scraper plate voltage value be 3.7V, and voltage value is 2.5V when passing through without object, illustrates that the chain rupture monitoring device 20 can be effective
Identify scraper plate, flat ring, vertical ring.
In the case where individual chain ruptures, by the first hall sensor 22, the second hall sensor 23 scraper plate quantity still
It is normal condition, conventional chain rupture monitoring device 20 detects the state due to being only able to detect scraper plate, it just cannot detect chain rupture,
Therefore, conventional 20 precision of chain rupture monitoring device is low, poor reliability.Chain rupture monitoring device 20 can identify flat ring in the utility model
With vertical ring, in this case, by the first hall sensor 22, the flat ring of the second hall sensor 23 and vertical number of rings amount and normal
In the case of it is inconsistent, judge chain rupture so as to effect.
Chain rupture monitoring device 20 in present embodiment can directly insert as needed into drag conveyor intermediate channel insert
In plate, there is no hindering coal stream to pass through, do not need to be transformed used mine flight conveyer yet.
The first permanent magnet 221, the second permanent magnet 222, Hall pedestal in chain rupture monitoring device 20 in present embodiment
223, Hall element 224 is all put together in stainless steel base 21, make entire chain rupture monitoring device 20 form one it is whole
Body, the design of this complete envelop-type, can effective protection chain rupture monitoring device 20, and integral design can be directly by chain rupture
Monitoring device 20 is inserted into sensor special tooling, is further avoided the impact by coal cinder and spoil and is damaged, moreover it is possible to convenient
Replacement after the failure of chain rupture monitoring device 20.
Here judgment module 142 is enumerated in a simple signal processor 10 to the deterministic process of chain rupture: usual situation,
Flat ring between two adjacent groups scraper plate, the quantity of vertical ring be it is specified, when 141 real-time monitoring two adjacent groups scraper plate of counting module it
