Intelligent coupling type two-column shield super-big mining height hydraulic support

Abstract

The invention provides an intelligent coupling type two-column shield super-big mining height hydraulic support. According to the intelligent coupling type two-column shield super-big mining height hydraulic support, intelligent coupling of the support and a surrounding rock top plate of a working face is achieved by installing various sensor modules and various intelligent control system modules on a two-column shield super-big mining height hydraulic support body according to the intelligent electrohydraulic control system technology, the sensor network technology, the network communication technology and the like; intelligent coupling of a support protecting shell and a coal wall is achieved; intelligent and coordinated operation of the support protecting shell, a telescopic beam and a coal cutter is achieved; automatic straightening of the support of the working face and intelligent on-machine control over the falling column, a movable frame, the rising column, the telescopic beam and the protecting shell are achieved; the perfect intelligent functions such as the self-diagnosis function and the prefect fault early warning function are achieved, the support can also be in seamless connection with a fully mechanized coal mining face centralized-control communication system, intelligent coordinated control and operation of the hydraulic support, the coal cutter and a scrapper are achieved, and automatic and intelligent coal mining can be achieved in an unmanned mode or with a small number of workers.

Description

technical field [0001] The invention relates to the field of one-shot full-height coal mining in an intelligent working face of a 10-million-ton large coal mine, in particular to an intelligent coupling type two-column shielding type extra-large mining height hydraulic support. Background technique [0002] my country is a major coal-producing country in the world, accounting for about 50% of the world's coal output. The production capacity and scale of my country's coal mining equipment manufacturing industry is the largest in the world, but the overall technical level and innovation ability are far behind the world's advanced level. In view of the current situation of the development of my country's coal machinery equipment manufacturing industry, according to the spirit of the "Outline of the Twelfth Five-Year Plan for National Economic and Social Development" and the "Decision of the State Council on Accelerating the Cultivation and Development of Strategic Emerging Indus...

AI Technical Summary

Problems solved by technology

Most of the international and domestic large-scale coal mines currently use tens of millions of tons of fully mechanized mining equipment, but have not yet adopted intelligent complete sets of equipment
