Abstract

The invention provides a chain fault detecting method and sensor for a side double-chain scraper conveyor. The sensor is used for detecting four common faults of chains of the side double-chain scraper conveyor, namely chain breakage, scraper breakage, rotation blockage and chain jumping, and comprises a support, probes and Hall components. During the use, the sensor is mounted right above chain wheels, when the conveyor runs, the chain wheels drive a scraper to collide with the probes of the sensor, and the probes are driven to swing regularly at an angle ranging from 0 degree to a degrees, and when the angle is 0 degree, the probes are opposite to the Hall components, and the sensor outputs high level, otherwise outputs low level, so that a pulse signal containing fault information can be obtained; and the fault of the chains of the side double-chain scraper conveyor can be analyzed and obtained through comparing the pulse signal with a standard pulse. The sensor can meet the requirement for real-time online measurement, has the essential safety characteristic, and can be applied to an explosive gas environment.

Description

technical field [0001] The invention relates to the field of fault diagnosis of mechanical equipment, in particular to a chain fault detection method and a sensor of a side double-chain scraper conveyor. Background technique [0002] Side double chain scraper conveyor is widely used in coal washing plants and coal mining face, etc. It is an important coal transportation equipment. The common faults of its chain include: broken chain, broken scraper, stalled and skipped chain. Timely and comprehensive detection of chain faults can ensure continuous production and improve economic benefits. At present, the existing detection methods can only be used to identify some faults, and the sensing devices are complex, so it is difficult to apply in the harsh environment of coal mining face. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a chain fault detection method and a sensor of a side double-chain scraper co...
