Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings.

[0024] Such as figure 1 , figure 2 As shown, the present invention is a scraper conveyor sprocket wear measurement device based on focus profile restoration. The sprocket 1 is provided with two rings of gear teeth, including an image acquisition device 10, a longitudinal centering device 11, and an arc centering device. Device 9. Wear measurement module 12;

[0025] The longitudinal centering device 11 moves longitudinally to make the image capture device 10 center the gear teeth in the longitudinal direction. The arc centering device 9 drives the image capture device 10 to make an equidistant circular arc movement along the sprocket 1 so that the image capture device 10 is aligned in the arc direction. In the middle gear tooth, the image acquisition device 10 is facing the detected gear tooth end surface and gradually approaches and collects the gear tooth image. The wear measurement ...

Abstract

A shape from focus based scraper conveyor chain wheel wear measuring device and a method in the invention belong to the technical field of equipment wear measurement. Provided are the shape from focusbased scraper conveyor chain wheel wear measuring device and the method which are capable of improving gear teeth measurement precision and efficiency, and reducing measurement cost. According to theinvention, the technical scheme is as follows: the device comprises an image acquisition device, a longitudinal alignment device, an arc alignment device and a wear measuring module, wherein the longitudinal alignment device longitudinally moves to make the image acquisition device align with a gear teeth in the longitudinal direction; the arc alignment device drives the image acquisition deviceto perform an equidistant arc motion along a chain wheel to make the image acquisition device align with the gear teeth in the arc direction; the image acquisition device faces and gradually approaches an end face of the detected gear teeth, and acquires gear teeth images; and the wear measuring module extracts a contour of the gear teeth from the acquired sequence gear teeth images by using a shape from focus technique, obtains a three-dimensional profile image of the gear teeth, completes depth measurement of a gear teeth surface profile, and obtains volume of the detected gear teeth.

Description

Technical field [0001] The invention relates to a scraper conveyor sprocket wear measurement device and method based on focus shape restoration, and belongs to the technical field of scraper conveyor equipment wear measurement and safety assurance. Background technique [0002] With the rapid development of science and technology, focus shape restoration and measurement techniques have received attention in many fields. Especially in the field of industrial wear, focused profile measurement has also been widely used. [0003] Scraper conveyor is the main production and transportation equipment for fully mechanized coal mining faces in underground coal mines. It is responsible for the important tasks of transporting coal, providing pushing fulcrums for hydraulic supports, and providing walking tracks for shearers. Its reliability directly affects the safety of modern coal mines. Efficient production. Sprocket is an important wearing part of scraper conveyor and is widely used in c...
