Intelligent adjustment system and method for fully mechanized coal mining face

Abstract

The invention provides a fully mechanized coal mining face intelligent adjusting system which comprises a distance measuring sensor, a stroke encoder, a permanent magnet, a beveling feed electromagnet and an angle adjusting electromagnet, and further provides a fully mechanized coal mining face adjusting method which is applied to the system and used for adjusting the advancing progress of a machine head or a machine tail of a fully mechanized coal mining face. That is, the advancing direction of the fully mechanized coal mining face is intelligently changed, and the machine head of the scraper conveyor moves out and retracts after multiple times of pushing in the process of adjusting the advancing direction of the fully mechanized coal mining face, so that the retracting and moving-out quantity of the machine head of the scraper conveyor caused by the gradient, the advancing direction and other factors of the fully mechanized coal mining face is eliminated. The lap joint length of the scraper conveyor head and the reversed loader is stabilized within a set threshold range of smooth coal flow conveying, and continuous and normal production of a fully mechanized coal mining face is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an intelligent adjustment system and method for a fully mechanized mining face. Background technique [0002] Due to the continuous movement of the crust, the level of the coal seam is less, and most of them are inclined. In actual mining, the transport and return tunnels connected to the working face are fixed spaces. Due to the existence of the inclination of the coal seam, the scraper conveyor (slider) is prone to deviation in the process of following the fully mechanized working face, that is, Compared with the phenomenon of indentation or protruding of the loader, the overlapping relationship between the scraper conveyor and the loader is unreasonable, and the space for the fully mechanized mining face to be transported back has been fixed. The indentation and escaping will cause the scraper conveyor to transport the coal flow poorly, and even cause the hydraulic suppor...

AI Technical Summary

Problems solved by technology

In actual mining, the transportation and backtracking roadways connected to the working face are fixed spaces. Because of the existence of the coal seam inclination, the scraper conveyor (slider) is prone to drift in the process of following the fully mechanized mining face, that is, Compared with the reloading machine, the phenomenon of indentation or escaping leads to an unreasonable overlapping relationship between the scraper conveyor and the reloading machine, and the space for transporting back and forth in the fully mechanized mining face has been fixed. Indentation and escape will cause the coal flow of the scraper conveyor to be poorly transported, and even cause the hydraulic supports of the fully-mechanized mining face to be squeezed, bitten or even collapsed, resulting in poor production. Smooth, stagnant and even affect production safety

[0003] At the same time, another reason for the indentation or escape of the scraper conveyor relative to the reloader is that the fully mechanized mining face is not perpendicular to the transport trough, that is, the fully mechanized mining face is in the position of the scraper conveyor during construction. One end of the head is ahead or behind the end of the tail of the scraper conveyor
