Problems solved by technology

However, this method can only reflect the relative position between each hydraulic support and the scraper conveyor, that is, there is no reliable reference point. When the scraper conveyor itself has been bent, even if the stroke sensor of each hydraulic support The readings are consistent, and there is no indication that a straightened state has been achieved

Embodiment Construction

[0023] see figure 1 As shown, a fully mechanized mining face hydraulic support and scraper conveyor automatic straightening method, including the following steps:

[0024] Step S101 , during the continuous advancing process of the fully mechanized mining face, the relative position between every two hydraulic supports is obtained through the first travel sensor installed on each hydraulic support.

[0025] In the present invention, a travel sensor for reflecting the relative position between the hydraulic supports is installed on each hydraulic support, and the relative position between every two hydraulic supports can be obtained by detecting the signal of the above travel sensor by the electro-hydraulic control system. As a better embodiment, the process of acquiring the relative position between every two hydraulic supports through the first stroke sensors installed on each hydraulic support may specifically include the following: through the sensor of the first stroke sens...

Abstract

The invention provides automatic straightening method and system for hydraulic supports and scraper conveyors of fully-mechanized coal mining working faces. The automatic straightening method includes steps of during continuous propelling of the fully-mechanized coal mining working faces, acquiring relative positions between every two hydraulic supports by first travel sensors mounted on the hydraulic supports; acquiring a relative position between each hydraulic support and one scraper conveyor; utilizing the appointed hydraulic support as reference, and straightening the hydraulic supports within an appointed range according to the relative positions between every two hydraulic supports until readings of the first travel sensors are zero; and utilizing the relative position of the appointed hydraulic support and the scraper conveyor as reference, and straightening the scraper conveyors within an appointed range according to the relative position between each hydraulic support and each scraper conveyor. By the automatic straightening method and system, the scraper conveyors and the hydraulic supports can be guaranteed to arrange orderly, and 'keeping the hydraulic supports, the scraper conveyors and cut coal walls straight and flat' of the fully-mechanized coal mining working faces is guaranteed.

Description

technical field [0001] The invention relates to the field of coal mining process control in fully mechanized mining working faces in coal mines, in particular to a fully mechanized mining working face hydraulic support and scraper conveyor automatic straightening method and a fully mechanized mining working face hydraulic support and scraper conveyor Automatic straightening system. Background technique [0002] "Three Straights and One Leveling" in the fully mechanized mining face is an effective means to realize the normal and efficient production of the fully mechanized mining face, especially when the working face passes through geological structures such as faults or folds, the working face equipment is difficult to adapt to the geological conditions, and it is necessary to ensure that the hydraulic support, cutting through The coal wall and the scraper conveyor are kept in a straight line, and effective control measures are taken to reduce the failure rate of equipment ...
