Abstract
The name of an anti-tear product for a belt conveyor is anti-tear detection rod for the belt conveyor. The anti-tear detection rod is installed at the interior of a feed opening, and as shown in figure 2, an alarm can be given when foreign matters such as large blocks and iron pieces are blocked at the feed opening of the belt conveyor, so that a belt is prevented from being scattered and torn. The anti-tear detection rod and a detection probe are in combined type, and are convenient to install, disassemble and maintain; as shown in figure 4, when tearing occurs to protect jump stop, after materials of the large blocks at the feed opening are treated, the production can be recovered just by changing a guide rod in an extremely short period of time under the condition that a circuit is not disassembled, so that the production efficiency is improved, only the guide rod is changed, a probe does not need to be changed, and the cost is reduced. According to the difference of the belt conveyor and conveying materials, the anti-tear detection rod is designed into various types, different materials such as plastic and alloy steel with a plurality of levels of strength and length are selected, and the anti-tear detection rod is suitable for various types of belt conveyors. A cable of an anti-tear detection probe uses a two-wire system and a four-wire system, and the voltage is alternating current and direct current 24V to 220V.
Description
Affiliated technical field
The present invention is a kind of belt feeder fender guard, for preventing conveying belt of belt machine longitudinal tear, longitudinally scratching, can detect belt feeder feed opening putty, get stuck.
Background technology
Conveying belt of belt machine longitudinal tear, scuffing are destructive destruction, loss is the most heavy, and current belt conveyor for preventing is torn two aspects of technical point, first is anti-tear belt, but this belt cost of manufacture is high, can not widespread use, second for tearing detector, after exposing, tear at belt, send warning, but do not have the effect that prevents belt tearing.
Summary of the invention
Can only after belt tearing, report to the police in order to overcome existing anti-tear device, invent belt conveyor for preventing and torn test rod, this test rod can send and tear warning in the time of preventing belt from scratches, allow belt feeder stop jumping, prevent vertical scratch on belt, tear, also can send warning for belt feeder feed opening card bulk, putty, scuffing belt prevents from blocking up, gets stuck simultaneously.
This anti-tear test rod solves the technical scheme that its technical matters adopts: at during belt conveyor operation, ironware or bulk exceed belt feeder feed opening discharge limit size, be stuck in feed opening, belt continuous running, and scratched by ironware or bulk, this damage occurs in feed opening inside, and on belt zone face, there is material to cover, be difficult to find in time, while is due to the trench structure of belt tension and carrying roller, force the belt of longitudinal tear to be still close together, scuffing place is leaked material seldom, can not judge belt tearing from leaking material situation, at the anti-tear test rod of the inner installation of feed opening, in the time that test rod is touched by ironware or bulk, can send warning, prevention preventing belt from scratches, tear.
The beneficial effect of this anti-tear test rod is, can be at belt feed opening putty, get stuck while scratching belt, send warning, and prevent belt tearing.

Detailed description of the invention
Fig. 1, foreign matter 4 is stuck in feed opening must two each stressed fulcrums, fulcrum 1 and fulcrum 2, can make to act on load-transfer device fulcrum 3 stressed, force this fulcrum to scratch belt, therefore, as long as a stress point is installed anti-tear test rod therein, just can before preventing belt from scratches, send warning, stop jumping belt feeder, effectively prevents preventing belt from scratches or longitudinal tear.Analyze this three fulcrums, the position of its central bearing point 1 and fulcrum 3 is unascertainable, varying in size of foreign matter, the position of stressed fulcrum 1 and fulcrum 3 is just different, simultaneously along with the motion of load-transfer device or tear, position can change, but fulcrum 2 is constant, therefore can be with fulcrum 2 as anti-tear test rod attachment point.
Fig. 2 is feed opening remodeling method, feed opening dotted portion is excised, outwards widen, in 8 (fulcrum 2) positions or forward and after downward-extension anti-tear test rod 1 is installed, after extension, can avoid material impact test rod, in the time can scratching the foreign matter of belt and fall into feed opening, along with the operation 10 of belt, object can block by tested measuring staff 1, cause test rod to occur bending and deformation, test rod sends " tearing warning ", belt feeder stop jumping, thus reach the object that prevention belt 2 longitudinally scratches and tears.
Install and use notice:
1, the thrust size during according to the size of tape transport material, density, resistance to abrasion and putty, the anti-tear test rod that selection intensity is suitable, so in advance false alarm prevention.
2, the necessary appropriate reconstruction of feed opening, allows anti-tear test rod 1 have certain deformation space, guarantees reliably to report to the police, and avoids material directly to wash away test rod simultaneously, affects service life.
3, anti-tear test rod must be horizontally through feed opening, and position is a little less than deflector chute, and two ends are fixed on deflector chute, and a terminal bolt is fixed, and other end perforation is fixing, and flexible surplus can be provided in the time that guide rod is out of shape.
4, anti-tear protection must access belt feeder interlocking.
Fig. 3, it is a kind of optoelectronic device that belt conveyor for preventing is torn test rod, formed by two parts: guide rod 1 and detection probe 8, guide rod is a kind of hollow circular-tube, and inner tubal wall is made black rough surface, can be coated with light absorbent 3, be used for absorbing light wave, tail end shutoff and plate metal reflex-reflective material 2 at inner end surface, head end is made into negative thread 4, is convenient to installation and measuring probe; Detection probe 8 is a kind of photoelectric control components, inner diode installed 9 and photo-transistor 10, two electro-optical tubes parallel arranged, the light keeping parallelism that the light of luminotron transmitting and photo-transistor are accepted, isolation mutually, circuit 11 is processed photosignal the output alarm signal that photo-transistor is accepted.
Fig. 4 is the principle of anti-tear test rod work: the luminotron 9 of detection probe is launched the light wave 7 of a branch of fixed carrier frequency, this light wave is arrived detection probe by metal reflective material 2 mirror-reflections of guide rod end face, received by photo-transistor 10, change current signal into and be transported to treatment circuit 11, light wave intensity and carrier frequency that this circuit relatively receives, intensity is normal, frequency is identical, judge that belt is normal, alarm free output, if the stressed bending of guide rod, the light wave that the luminotron of detection probe sends is absorbed by black tube wall, photo-transistor does not receive the reflecting light of fixed carrier frequency, or light wave intensity is very weak, after processing of circuit, sending immediately reports to the police shuts down.Circuit is divided into two-wire system and four-wire system, both by rectifying circuit, mu balanced circuit, light-emitting diode, photo-transistor, control circuit composition, alternating current or the uncertain direct current (DC) of direction are converted to inner direct current (DC) by rectifying circuit, be transported to mu balanced circuit, LED power source and photo-transistor power supply are provided after voltage stabilizing, photo-transistor output signal is transported to comparison control circuit through amplifying, control circuit is according to the power of photo-transistor signal, send warning, two-wire system loop is by controlling internal resistance size, change commutating circuit total current and carry out output alarm, four-wire system loop is directly to control output switch contact.
