Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] The straightness detection system of the fully mechanized working face scraper conveyor described in the present invention is as follows: figure 1 As shown, it consists of a scraper conveyor 2 and two inspection vehicles 1 installed at both ends of the scraper conveyor 2. Under the trigger of an external control signal, the inspection vehicle 1 moves back and forth along the scraper conveyor 2 to detect motion parameters and It is converted into the straightness information of the ...

Abstract

The invention discloses a flatness detection system and method for a fully-mechanized face scraper conveyer. The detection system is composed of the scraper conveyer and two detection vehicles mountedat the two ends of the scraper conveyer. The detection vehicles stride over the scraper conveyer. When the flatness of the scraper conveyer needs to be detected, the detection vehicles move along thescraper conveyer, inert measurement units and encoders in the detection vehicles collect relative motion data, the data are processed by a controller to obtain flatness information, and finally flatness is sent to an outer control device. According to the flatness detection system and method, sensors are prevented from being directly mounted on a coal mining machine, the adverse effects of vibration and the slow motion speed of the coal mining machine to flatness detection are overcome, the performance requirements for the sensors are reduced, and the flatness of the working face can be measured more efficiently and precisely on the premise of the lower cost.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a detection system and a detection method for the straightness of a scraper conveyor in a fully mechanized mining face. Background technique [0002] In order to achieve long-term and unmanned mining in the intelligent fully mechanized mining face of coal mines, it is necessary to ensure that the entire working face can maintain a good straightness during the real-time advancement process. If there is a large bending and undulation of the working face, the production needs to be stopped immediately, and the normal production work can be started after the working face is artificially straightened, which greatly reduces the production efficiency and greatly restricts the further large-scale promotion of the intelligent fully mechanized mining face in coal mines. [0003] The existing scraper conveyor straightness detection system generally relies on the shearer, combined with t...
