Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] A scraper conveyor straightness monitoring method of the present invention, such as Figure 1 ~ Figure 4 shown, including the following steps:

[0023] S10: Lay the fiber grating three-dimensional curvature sensor 2 in the cable groove 1 of the scraper conveyor 4 on the working face, so that the bending shape of the fiber grating three-dimensional curvature sensor 2 is consistent with the bending shape of the scraper conveyor 4, and make the fiber grating three-dimensional curvature sensor 2 The side close to the transport trough 6 of the working surface is fixed, and the side close to the return trough 5 is in a free state; specifically, the fiber grating three-dimensional curvature sensor includes: a flexible substrate 21 arranged along the extension direction of the cable trough 1, The flexible substrate 21 can be deformed along with the deformation of the cable ...

Abstract

The invention discloses a straightness monitoring method for a scraper conveyor. The method comprises the following steps that S10, a fiber bragg grating three-dimensional curvature sensor (2) is laidin a cable trough (1) of a working face scraper conveyor (4), the bending form of the fiber bragg grating three-dimensional curvature sensor (2) is enabled to be consistent with the bending form of the scraper conveyor (4), one side, close to the working face conveying gate road (6), of the fiber bragg grating three-dimensional curvature sensor (2) is enabled to be fixed, and one side, close to the air return gate road (5), of the fiber bragg grating three-dimensional curvature sensor is enabled to be in a free state; and S20, curvature information on two orthogonal planes of the fiber grating three-dimensional curvature sensor (2) is acquired, algorithm derivation is performed by using linear interpolation, and three-dimensional bending form fitting reconstruction of the scraper conveyor(4) is performed. The method is small in error, high in monitoring precision, good in reliability and convenient to detect.

Description

technical field [0001] The invention relates to the field of straightness monitoring of scraper conveyors in fully mechanized mining working faces under mines, in particular to a method for monitoring straightness of scraper conveyors. Background technique [0002] At present, in order to get out of the dilemma of safe and efficient automatic mining in my country's coal mines, it is necessary to vigorously promote the intelligent and unmanned process of coal mine working faces. Machine straightness perception technology, as the key technology, has attracted the attention of researchers at home and abroad. In the prior art, technologies for straightness perception of scraper conveyor include: manual straightening, scraper conveyor straightness perception technology based on wire rope sensor, scraper conveyor straightness perception technology based on ultrasonic sensor, hydraulic pressure based The scraper conveyor controlled by bracket electro-hydraulic will have straightnes...
