Problems solved by technology

[0003] Since the circular link chain and the scraper move together in the middle groove during normal operation, the traditional wired detection method cannot detect the tension of the circular link chain in real time. Scholars at home and abroad have conducted a lot of theoretical analysis on the tension of the circular link chain, but its Accuracy can't be verified
Traditional detection methods and data transmission all use wired transmission methods, but the scraper chain is moving and cannot use wired methods

Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] figure 1 A flow chart showing the method of the present invention for detecting the tension of a circular link chain on a scraper conveyor;

[0022] refer to figure 1 , a method for detecting the tension of a circular link chain on a scraper conveyor according to an embodiment of the present invention includes:

[0023] S1, collecting tension information of at least one link in the circular link chain;

[0024] S2. Send the tension information wirelessly;

[0025] S3. Receive the tension information through at least one wireless receiving device within a predetermined range around the circular link chain.

[0026] In one embodiment, the tension information is collected by a tension sensor arranged on a link at intervals of a preset number of links on the circular link chain.

[0027] Specifically, the circular link chain of the scraper convey...

Abstract

The invention relates to a method for detecting the tension of a round-link chain on a scraper conveyer. The method is characterized by comprising the steps as follows: S1, collecting tension information of at least one link of the round-link chain; S2, sending the tension information in a wireless manner; S3, receiving the tension information through at least one wireless receiving device in a preset range around the round-link chain. According to the method, data are transmitted in the wireless manner, so that the tension and the working state of the round-link chain can be monitored in real time.

Description

technical field [0001] The invention relates to the field of mining technology, in particular to a method for detecting the tension of a circular link chain on a scraper conveyor. Background technique [0002] The scraper conveyor is the main production and transportation equipment for underground coal mining in coal mines. The circular chain is an indispensable part of the scraper conveyor, and it is also the weakest part of the scraper conveyor. The common scraper of the scraper conveyor Faults such as broken chain, skipped chain or dropped chain are all related to the tension of the scraper conveyor circular chain. [0003] Since the circular link chain and the scraper move together in the middle groove during normal operation, the traditional wired detection method cannot detect the tension of the circular link chain in real time. Scholars at home and abroad have conducted a lot of theoretical analysis on the tension of the circular link chain, but its Accuracy cannot b...
