Scraper state detection device of scraper conveyor

Abstract

The invention relates to a scraper conveyor, in particular relating to a scraper state detection device of a scraper conveyor. According to the invention, the problems in the prior art that the passing of coals can be influenced the sensor has high possibility of being damaged by the coal flow. The scraper state detection device is a magnetic conductive device mounted in the chute of the scraper conveyor, wherein the chute consists of a left chute edge, a right chute edge and an intermediate chute plate. The magnetic conductive device comprises NdFeB permanent magnets, a magnetic conductive material and a Hall element, wherein two NdFeB permanent magnets are respectively mounted on the planes of the left chute edge and the right chute edge, and are connected with a horizontal magnetic conductive material; lateral magnetic conductive materials connected with the magnetic conductive material are respectively arranged on the side surfaces of the left chute edge and the right chute edge; bottom magnetic conductive materials connected with the lateral magnetic conductive material are arranged on both sides of the intermediate chute plate; two Hall elements are respectively mounted on the upper surfaces of the two bottom magnetic conductive materials through screws; a stainless steel plate is arranged on the upper surfaces of the Hall elements to protect the Hall elements; and the two Hall elements are connected with a synchronous identification system. The scraper state detection device is suitable for protecting the scraper conveyor.

Description

technical field [0001] The invention relates to a scraper conveyor, in particular to a detection device for the state of the scraper of the scraper conveyor. Background technique [0002] The scraper conveyor is a commonly used pivotal equipment in coal mine production. Whether it works normally or not plays a vital role in the safe production of the entire coal mine. However, at present, during the operation of the scraper conveyor, there are often breakage accidents of the circular link chain. Every time there is a broken chain, if the shutdown is not timely, it will also cause piles of chains and coals, causing the entire working face to stop production and causing huge economic losses. Statistics show that the broken chain accident of scraper conveyor accounts for about 52.12% of the total number of scraper conveyor failures. Therefore, it is particularly important to analyze the cause of the broken chain accident of the scraper conveyor and prevent it. [0003] At pr...
