Description
Technical field
The present invention relates to conveyor tear detection technique field, and in particular to a kind of underground belt conveyor discerption detecting device and
Method.
Background technology
Underground belt conveyor is the visual plant of ore deposit delivered downhole ore and coal etc., its freight volume is big, working environment is complicated,
Bearing capacity is strong, and transportation range it is more long the features such as, it is widely used in mine.But in transportation
In, sharp coal cinder or ore readily penetrates through belt and causes belt tearing, gently then influences production efficiency, heavy then bring cannot
The production accident retrieved.
Current underground belt tearing detection, mainly detect skin by having detected whether that coal cinder or ore drop
Whether band tears, and is not find belt tearing in time the drawbacks of this detection method, but brought with belt tearing
Consequence verifies whether belt tears, and to do so may bring bad consequence.Simultaneously belt be mainly by rubber, silica gel,
The materials such as PVC are made, and have certain elasticity, even if so belt has torn sometimes, also not necessarily having crack, it is impossible in time
Detect, so as to cause to tear further exacerbation, or even cause security incident.
The application number disclosed in Chinese patent application：A kind of belt tearing mouthful is disclosed in 201510801512.2 patent
Extension fixture and method, it mainly by two expansion roller groups into, expansion roller by expansion flat carrier roller and expansion oblique idler constitute, and
Installed in the lower section of belt, along the longitudinally asymmetric distribution of belt, laterally there is certain angle with belt.The effect of the device is to skin
The crack of belt tearing is expanded along the power in belt transverse direction with applying one, allows coal cinder to fall to trigger belt tearing alarm.This
Method can make coal cinder be fallen along crack and trigger alarm in time, but crack is sufficient for coal cinder and falls, and illustrate that crack is already very big,
Longitudinal tear is very long in other words, and it is ageing not high that it is alarmed.
The application number disclosed in Chinese patent application：A kind of belt tear-preventing is disclosed in the patent of 201410358351.X
Detection means and method, the patent detect belt tearing situation using the method for image recognition.Generating laser is under belt
The ribbon laser of surface emitting one, then by same position in 3D camera acquisition laser stripe distribution situations and whole picture
The data of collection are transferred to terminal by the longitudinal crack feature put, control main frame, are compared with value set in advance
Analysis, so as to judge whether belt tears.The method increase the accuracy of detection, but realize it is relatively difficult, technique compared with
It is complicated.
The content of the invention
Regarding to the issue above, the present invention provides a kind of simple, efficient, accurate underground belt conveyor discerption detecting device and side
Method.
In order to solve the above problems, the scheme that the present invention is provided is：
A kind of underground belt conveyor discerption detecting device, including tear detection part and breach extension fixture, the tear inspection
Surveying part includes fixed support, infrared stripes optical transmitting set, infrared light receiver, controller and warning device, and the breach expands
Device includes that belt expands carrying roller and roller rack, the infrared light receiver and the warning device respectively with the control
Device is connected, and the controller embeds timer.
Preferably, the fixed support is divided into upper bracket and lower carriage, and the two is connected using pipe clamp fixes, and is maintained at same
In one plane, while plane where fixed support need to be vertical with belt direction of travel.
Preferably, the infrared stripes optical transmitting set is arranged on the top of lower carriage, positioned at the lower section of belt.
Preferably, the infrared light receiver is arranged on the lower section of upper bracket, and the controller and the warning device are pacified
Mounted in the top of upper bracket, three is all located at the top of belt.
Preferably, the warning device is by the way of sound and light alarm.
Preferably, the belt expands carrying roller installed in infrared stripes optical transmitting set and the rear of infrared remote receiver, and
With belt laterally in 20 °~30 ° of angle on horizontal plane, the roller rack uses triangle framework.
Preferably, whole underground belt conveyor discerption detecting device is arranged on the rear of coal dropping port, apart from coal dropping port 1m or so.
A kind of detection method of above-mentioned underground belt conveyor discerption detecting device, specifically, when belt runs to expansion carrying roller,
Carrying roller has a component for transverse direction to belt, and the component is enough to expand the belt of tear, then infrared stripes optical transmitting set
Launch a branch of infrared stripes light, if tear occurs in belt, the infrared light that infrared stripes optical transmitting set is launched shines through crack
The timer being mapped in infrared light receiver, i.e. trigger controller starts timing, when infrared light receiver does not receive infrared light
Stop timing, the speed of now controller combination belt feeder calculates the length of belt tearing, if tear length is less than 1m, not
Influence belt normally runs, and warning device does not send alarm, if tear length is in 1m~10m, warning device sends one-level alarm,
Belt feeder can normally run the short time, and remind staff's on-call maintenance, if tear length is more than 10m, warning device sends
Secondary alarm, belt feeder can not rerun, and staff should power off and repair to belt feeder immediately.
The present invention have the advantage that compared with prior art for：The present invention aids in infrared bar using belt expansion carrying roller
The detection of line light, improves the accuracy of detection；In view of might have horizontal linking seam and extremely short vertical at belt lacings
Belt normal work can't be influenceed to tear, therefore the crack that setting is detected within 1m does not send alarm；When detecting tear
It is divided into two-stage alarm, tackles the generation of Splitting with the sufficient time to staff.
