A kind of belt conveyor tear detection method, comprises the steps:
S01, arranging pendulum angle detection lug 2 in the end of the swinging axle 5 linked with roller 1, detect the deflection angle of swinging axle 5 in real time, and be connected to belt control device by one piece of proximity switch, described roller 1 is arranged on above belt conveyor 6；
If S02 pendulum angle detection lug 2 detects that swinging axle 5 exists deflection angle, belt control device record swinging axle 5 deflection time, when deflected between exceed Preset Time, then send alarm signal.
Above-mentioned belt conveyor 6 tears detection method and also comprises the steps:
M01, revolution detection lug 3, the rotating cycle of real-time inspection center axle are set in the central shaft end of roller 1 rotation, and are connected to belt control device by one piece of proximity switch；
If M02 revolution detection lug 3 detects that roller 1, around central shaft rotation, the most often from turning around, sends pulsatile once to belt control device；
The pulse number that M03, accumulator rotation counting detection lug 3 send, when exceeding predetermined pulse number of times, sends alarm signal.
Described step M03 is particularly as follows: integrating instrument calculates summation pulse number of times, within a certain period of time, without new pulse accumulation, then accumulated value starts gradually to successively decrease by given pace, until accumulated value returns 0, if there being new pulse to occur in this process, then continue cumulative, if accumulated value exceedes preset value, send alarm signal.
As it is shown in figure 1, this device has a rotatable roller 1, roller 1 is placed on a swinging axle that can swing 5.Roller 1 can be along swinging axle 5 swing, can also rotate around the rotary shaft 4 of self, rotary shaft 4 head of roller 1 connects a revolution detection lug 3, uses inductive type the first proximity switch to detect it, when roller 1 rotates a circle, a pulse signal can be produced.The head of swinging axle 5 connects a detection lug equally, uses the second proximity switch to detect whether to produce swing.The signal of two proximity switches all inputs to belt control device by signal relay.
This device, along reclaimer operation belt 6, is evenly arranged several at a certain distance, is positioned at above return belt 6.Distance between roller 1 and return belt 6 through test after according to actual coal breakage size depending on.If when tear occurs backhaul coal breakage more and passes through on the downside of device, by jack-up roller 1 and swinging axle 5 thereof, making roller 1 swing along homeward journey direction, swinging axle 5 now drives swing detection sheet to turn an angle.Second proximity switch is used for detecting pendulum angle, if swinging signal exceedes Preset Time and resets not yet, now produces warning stopping signal.
If coal breakage flow is less during tear, then, when coal breakage passes through on the downside of device, owing to roller 1 is less with belt 6 gap, coal breakage will produce friction with roller 1.Under frictional force effect, roller 1 is constantly driven to rotate.Revolution detection lug 3 will make the first proximity switch constantly produce pulse, and program judges whether to produce warning, stopping signal by the accumulated value of pulse and the seriality of pulse.Dropping the ut on return belt 6 for occasional in normal operation, program will not produce warning stopping signal.
For splashing down a small amount of coal cinder on backhaul face during operation once in a while, the number of pulses of generation is little, disappears in the prepulse exceeding preset value, and accumulator now stops being incremented by, and program then keeps current accumulation value 2s, waits whether pulse continues to occur in the process.If there being coal cinder to continue to fall in belt 6 backhaul face, then pulse continues occur that accumulated value continuation increase is shut down until cumulative pulse is reported to the police after exceeding preset value；If pulse no longer occurs, after 2s, accumulated value starts gradually to successively decrease by given pace, until accumulated value returns 0.During successively decreasing, produce pulse if there being coal cinder to fall in belt 6 backhaul, then stop successively decreasing and continuing to be incremented by by umber of pulse on the basis of current accumulation value.
Dynamic action and the shake of whole conveyer due to return belt 6 carrying roller, return belt 6 is shaken together as well as whole device, in order to avoid causing the false touch of whole detection device to move because of the shake of belt 6, therefore, being provided with hold down gag in detection device region, hold down gag is made up of at least 8 contact rollers, is arranged in four angles in detection region, the each corresponding contact roller of belt about 6, compresses the belt 6 in whole detection region.Contact roller can be rotated about its center axis, with the friction reduced and between belt 6.Central shaft is fixed on side stand by nut, and side stand has waist-shaped hole, it is simple to the position of regulation contact roller, acts on the pressure on belt 6.
For large-scale coal cinder, likely fall and blocked by swinging axle 5 on return belt 6, without the hole below swinging axle 5 passes, thus without being detected, if coal cinder is piled up, the safety of whole device can be affected, therefore, front at roller 1, reflective type photoelectric sensor it is provided with on the support of both sides, emitter and receptor are installed in the side of belt feeder, opposite side and the installation reflector of emitter correspondence position at belt feeder, the light that emitter sends is received by photoelectric sensor light receiving device after reflector reflects, illustrate do not have foreign body to block reflective, then judge do not have foreign body to pass through, for normal condition, belt feeder continues to run with.When there being foreign body to block, light receiving device does not receives reflection light, then be judged as having foreign body to pass through, then alarm signal inputs to belt control device.The installation site of emitter and receptor should be higher than swinging axle 5.
