Abstract
The utility model provides a novel method and a device for detecting the stretching of belts, which belong to the field of detection technology, and are particularly suitable for the non-destructive inspection of the stretching state of running belts. In the utility model, signal generators are inbuilt in the edges on the both sides of a running belt, and the signal receivers installed above or below the belt send signals to a single-board computer and a computer to carry out processing (comparison, analysis, judgment, induction, synthesis and storage.) to make tensile curves and data forms for each section. Furthermore, various data of detected sections can be displayed at any time, and the utility model carries out audible and visual alarm on transfinite detected sections.
Description
The utility model belongs to the detection technique field, is particularly suitable for moving the Non-Destructive Testing under the apron drawing state.
Current, the automatic production line of units such as some mines, harbour, storage and each manufacturing enterprise, the belt transport unit of when transportation material (coal, ore, goods), article (product), workpiece, sampling widely, it is safe and reliable, the efficient height, low cost of manufacture is subjected to user's favor deeply.But, in long operation, when especially freight volume is big or heavily loaded, the plastic yield of belt continues to increase, and all has the situation of the fracture of pulling to take place at any time, causes a serious accident and serious accident, not only have a strong impact on production efficiency, but also caused enormous economic loss.
At present, the detection method to the operation belt has following several: shut down hand inspection, this method is mainly observed the surface state of belt, sees to have or not scuffing, fracture, and neither science is also inaccurate, and stop time is long, influences the production efficiency of belt transporting facility; Another is to adopt to shut down X ray film making inspection, this method contaminated environment, and stop time is long, and security alarm function in advance can only regularly be spot-check, do not had to the cost height; Also having a kind of is to adopt powerful X ray, and ultrasound wave CT carries out the way of image analysis processing, storage, adopts its equipment price costliness of this detection technique, and complicated operation also is difficult to promote in the enterprise at present at home.Therefore, design a kind of safe and reliablely, the cannot-harm-detection device of the operation apron drawing state of low cost of manufacture is to be badly in need of at present the big technical barrier that solves.
The purpose of this utility model is to design a kind of the cannot-harm-detection device of moving the apron drawing state.This device do not have wearing and tearing, precision height, safe and reliable, can detect the extended state that moves belt at any time, and have functions such as prompting, warning.
The cannot-harm-detection device of this operation apron drawing state, its main points are: on the both sides of the edge of operation belt 4, separated by a distancely bury a signal generator 1 underground, between per two signal generators apart from the very important person for demarcating; If have the strong belt of wire rope, signal generator should be embedded in the both sides (see Fig. 4,5 is wire rope among the figure, and 6 is the end of wire rope) of connector area so, and signal generator can be the powerful permanent material, also can be miniature pulse signal generator; Above or below the both sides of the edge of operation belt 4, two groups of signal receivers are set respectively, preceding group signal receiver 3 is one road receiving element, the receiving element of back group signal receiver 2 is more than at least 4 the tunnel, distance between this each sensor of group signal receiver is 10mm～100mm, signal receiver is the magnetosensitive switching tube, also can be mistor, Hall element, inductance component and capacitor element, signal receiver links to each other with single card microcomputer by data channel, and single card microcomputer links to each other with computing machine by interface bus.
Its principle of work is: when the belt generator 1 of operation produces data-signal during through signal receiver 2,3, data-signal carries out filtering, delivers to computing machine after level and smooth and carry out data processing (comparison, judgement, reasoning) through single card microcomputer, draw the determining of belt to tension values and relative tension values, data to each section extended state accumulate, deposit the personal data storehouse, and make the stress strain curve and the data form of each section, in order to calling at any time, the detector segments that transfinites is carried out sound and light alarm.(see figure 2)
Accompanying drawing and example:
Fig. 1 is the test section structural representation
Fig. 2 is a system chart
Fig. 3 is an ordinary straps signal generator position view
Fig. 4 is a strong belt signal generator position view
Accompanying drawing 1 is disclosed to be an example of the present utility model, and signal generator 1 is embedded on the both sides of the edge of operation belt 4, and signal generator 1 adopts the powerful permanent material, and the distance of two adjacent signals generators is 1500mm.Two groups of signal receivers 2,3 are installed in the top of operation belt 4; preceding group signal receiver 3 is one road receiving element; back group signal receiver 2 is 4 road receiving elements; the receiving element of preceding group signal receiver 3 is 1500mm with the distance of first unit of back group signal receiver 2; distance between each sensor of back group signal receiver is 10 ± 0.1mm, scraper plate and safety screen is installed with the guard signal receiver in the front portion of signal receiver.
Relation is as follows in Fig. 2 system chart: when belt normally moves, when the belt movement signal generator fixed receiver 2 of process and 3, produce signal separately respectively.The front end of detection system removes on-the-spot undesired signal through filtering, again through amplifying, is connected to multicircuit switch so that touring four road signals that detect.The signal that obtains carries out the A/D conversion through sampling hold circuit and D/A converting circuit, the digital signal that obtains can be delivered to single card microcomputer and handle (comprising filtering, selection, collection), also can directly data be delivered to main frame compare, analyze, comprehensively, reasoning, judgement, selection, storage etc. handle, draw out various stress strain curves and form for inquiry by main frame at last, and give sound and light alarm and prompting at abnormal occurrence timely.
This device advantage is:
One, the utility model is a kind of noncontact the cannot-harm-detection device, and the precision height is safe and reliable, manufactures This is low.
Two, real-time online detects, and avoids a large amount of shutdown, the off-time of manual detection, greatly improves skin Productivity effect with transporting equipment.
Three, detect by long-term follow, can analyze the pulled out condition that belt is in operation,, guarantee that belt moves safely and effectively so that make decisions and maintenance in time to the operation belt.
Four, this device is monitored in real time to the operation belt, and the generation of serious accident is avoided in fracture when preventing belt work, has great economic benefit and social benefit.
