Abstract

The invention relates to a detection device for straightness of a scraper conveyer and a detection method. The detection device comprises a data collecting unit, a communication unit, a data processing unit, a data storage unit, an alarming unit and a power supply module. The detection method comprises the following steps: collecting tri-axial accelerated speed, tri-axial angular speed and tri-axial magnetic induction intensity of each section of middle slot (2) in a pushed process of the scraper conveyer by the data collecting unit; acquiring the tri-axial angular speed and the tri-axial accelerated speed into an MEMS (Micro Electro Mechanical System) sensor on each section of middle slot (2) by the data processing unit, performing time integration and then acquiring a tri-axial angle and a tri-axial displacement and recognizing an S curve of the scraper conveyer; adopting a difference method for reducing the tri-axial displacement measurement error; adopting an AHRS (Attitude and Heading Reference System) algorithm and an average method for reducing the tri-axial angular measurement error; establishing a space absolute coordinate system and performing curve fitting, thereby acquiring the curve of the scraper conveyer. The device and the method are beneficial to the efficient and accurate detection for the straightness of the scraper conveyer.

Description

technical field [0001] The invention relates to the detection of the straightness of a scraper conveyor and a hydraulic support in a fully mechanized mining face in an underground mine, in particular to a detection device and a detection method for the straightness of a scraper conveyor. Background technique [0002] With the continuous development of mining machinery and equipment, the degree of mechanization and intelligence of the coal mining face has been continuously improved, and more and more coal mines have adopted the "three-machine matching" automatic coal mining technology. In the fully mechanized mining face, the three machines are mutually conditioned and cooperate organically. The hydraulic support provides support space for the shearer and the scraper conveyor to ensure the safety of equipment and personnel; the shearer moves with the scraper conveyor as the guide rail, and cuts the coal wall during the movement to complete the "coal mining " and "falling coa...
