Abstract
The present invention belongs to the technical field of the health diagnosis of mining equipment. An X-ray emitting device and a receiving device are used for collecting and treating image information of a steel core wire structure in a strong conveyer belt in operation by a microcomputer, and the image information are converted to visible images on a monitor. A person on duty directly watches the steel core wire structure in the strong conveyer belt so as to determine whether each strand of steel wire breaks or not or whether the malposition of a joint occurs. Therefore, signals predicting the possible transverse breakage of the strong conveyer belt can be sent out for person concerned to treat in time. The visible image information can be alternately stored in the peripherals of a computer for later enquiry.
Description
The present invention relates to the mine with the conveyer belt predictor that ruptures.
The mine is to use major part on a kind of large transport airplane in the mine produces with strong conveyer belt, cross break is one of grave accident of such conveyer belt, as the strong belt in China Yanzhou Mining Bureau Xinglongzhuang Coal Mine, the employed belt transporter in Fengfeng Mining Bureau Xue Cun colliery the cross break accident takes place all.For a long time, people just wish to find a kind of reliable measure of forecasting this class accident, but even to this day, still are unrealized.At present, very simple and crude way is mostly adopted in forecast to this class accident, if any unit send dynamo-electric maintainer to observe the strong conveyer belt joint every day bulge whether to occur, the unit that has again goes out mark in the joint of strong conveyer belt with graduating with cutter, send every day dynamo-electric maintainer to measure, see whether the plastic deformation (elongation) of joint surpasses permissible value with steel ruler.This class Forecasting Methodology efficient is low, and error is big, and can not take comprehensive situation of strong conveyer belt into account.The unit that also has goes a step further, the method that adopts X to take pictures detects the intact situation of wire cored wire in the strong conveyer belt, (1m is wide for a joint but take pictures, 2m is long) just need 17 more than of 12 inches photographic plats, this method not only taken a lot of work, but also time-consuming, no matter (1m is wide to the conveyer belt total length in this way economically or on efficient, 2000-3000m is long) take pictures and may not, and the staff is for a long time near x-ray source work, and also very unfavorable to its health, effect is bad.
Purpose of the present invention: provide a kind of device that can make the transport plane maintainer can observe failure condition such as disconnected strand of wire cored wire and radius off-set joint in the strong conveyer belt intuitively, all sidedly, improved the reliability and the promptness of failure prediction.Simultaneously, the maintainer avoids the irradiation of X ray away from x-ray source, has improved the safety of its work.
The concrete implementation content of the present invention: utilize x-ray source emission X-ray line, this X-ray line passes operating strong conveyer belt and shines on the one-dimensional array that photodiode (or photo-transistor) that crystal is covered with forms, the image transitions of strong conveyer belt inner structure is become the photoelectric current signal, this signal is gathered by microcomputer, handle, and be converted to monitoring device (telltale of high resolution) and go up the visual picture signal, the testing staff can directly see the whole circumstances of wire cored wire the strong conveyer belt from screen, when wire cored wire has problem (disconnected strand or dislocation), the staff can observe directly, chopping machine also can be printed out of order simple declaration automatically simultaneously, and is for reference.In case of necessity, the staff can handle keyboard, the failure message on the image is stored in the peripheral hardware (hard disc or flexible plastic disc) of computing machine, in order to inquiry afterwards.The block diagram that patent device therefor of the present invention is formed as shown in drawings, wherein: 1, X source (X-ray emitter); 2, strong conveyer belt, direction shown in the arrow is the conveyer belt service direction; 3, opto-electronic conversion one-dimensional array and multiplying arrangement thereof; 4,16-bit microcomputer and telltale; 5, monitoring device; 6, chopping machine.
Advantage of the present invention is: adopt image processing techniques, on the basis of x-ray fluoroscopy technology invisible image transformation is become visual picture, whether for whole states of wire cored wire in testing staff's direct viewing strong conveyer belt, observing it has disconnected strand or radius off-set joint.Simultaneously, chopping machine also can automatically record the situation of fault simply.In addition, the viewer also can go operating buttons as required, graphicinformation in bad order is stored in the peripheral hardware of computing machine.
