Intelligent atomizing large-mining-height cable duct and atomizing method thereof

Abstract

The invention discloses an intelligent atomizing large-mining-height cable duct and an atomizing method thereof. A coal cutter position monitoring module is installed on a coal cutter body so as to monitor the position information of the current cutting part of a coal cutter in real time. An electromagnetic stop valve position recognition module is installed on each electromagnetic stop valve so as to monitor the position information of the corresponding electromagnetic stop valve. An electromagnetic stop valve driving module is electrically connected with the electromagnetic stop valves and further controls the electromagnetic stop valves. Each electromagnetic stop valve is provided with the corresponding electromagnetic stop valve position recognition module. The coal cutter position monitoring module, the electromagnetic stop valve position recognition modules and the electromagnetic stop valve driving module are all electrically connected with a judgment module. The judgment modulejudges whether the position information of the electromagnetic stop valves corresponds to the position information of the cutting parts or not according to the collected position information of the cutting parts and the position information of the electromagnetic stop valves, control signals are sent to the electromagnetic stop valve driving module according to judgment results, and therefore theelectromagnetic stop valve driving module drives the electromagnetic stop valves to move. An atomizing system sprays mist for the cutting parts, dust is reduced and the working environment is improved.

Description

technical field [0001] The invention relates to the field of cable troughs for scraper conveyors used in underground working faces of coal mines, in particular to an intelligent spraying large mining height cable trough and a spraying method thereof. Background technique [0002] my country is the world's largest coal-producing country with abundant coal resources, among which thick coal seam resources account for about 44.8% of the total coal reserves. Thick coal seam mining technology is becoming more and more mature. At present, most major domestic coal enterprises adopt full-height and large-height fully mechanized mining. Technical mining of thick coal seams has the advantages of high mining efficiency, low mining cost, and less waste of coal resources. However, the fully mechanized mining technology with full height and large mining height at one time faces many technical difficulties. etc. put forward higher requirements. [0003] During the mining process of the worki...

AI Technical Summary

Problems solved by technology

[0003] During the mining process of the working face with large mining height, due to the high mining face, the working face is prone to beading or oversized coal blocks, and the impact of oversized coal blocks falling from a high place on the heightened coal retaining plate of the cable trough of the scraper conveyor is very severe. Serious, it is very easy to smash and bend the cable trough and increase the height of the coal retaining plate to cause damage

At the same time, a large amount of coal cut by the cutting drum of the shearer falls from a high place, which easily produces a large amount of dust, which deteriorates the working environment and affects the health of the operators.

Coal falling from a height has high kinetic energy, and it is easy to roll over the scraper conveyor cable trough and heighten the coal retaining plate, which seriously affects the normal operation of the hydraulic support and the personal safety of the operator. Therefore, the design must increase the height of the cable trough. The height of the coal slab, but the height of the cable trough and the height of the coal baffle will exceed the visual height of the operator, which will affect the operator's observation of the working status of the equipment on the coal wall

[0004] In addition, the laying length of the scraper conveyor is long, and the coal on the scraper conveyor is in a moving state. The total coal loading of the scraper conveyor is not easy to detect, and cannot provide parameters for the intelligent speed control system.
