摘要: 为抓捕断裂或者倒转打滑的输送带,从而减少输送带断裂造成的破坏与损失,介绍了一种新型全断面断带抓捕器,阐述了该抓捕器的结构与动作原理,并根据理论力学基本知识分析了抓捕过程,给出了抓捕器实现断带抓捕的条件,并分析了夹持角与摩擦因数等对抓捕效果的影响规律。研究结果表明:当夹持角θ与摩擦因数α满足1/α≤tanθ时,抓捕器可形成自锁,即在结构与输送带强度允许范围内,抓捕器可以提供足够大的抓捕力夹持断带;当1/α>tanθ时,抓捕器不能形成自锁,此时机构存在最大抓捕力,且与配重、夹持角以及摩擦因数有关,可根据实际需求配重调整等方法实现抓捕。Abstract: In order to study the unmanned mining technology with a visualized remote interference,an analysis was conducted from the technical principle,general plan and system functions. An unmanned mining production mode with " unmanned operation and manned patrol" was provided. Thus a humanoid technique was applied and the human vision and auditory were extended to the coal mining face. The miners could be liberated from the danger coal mining face to the mine relevant safe roa dway monitoring and contral center or on the surface ground and a remote operation control from the mine roadway monitoring and control center could be conducted 0n the powered supports,coal shearer,scraper conveyor and other fully-mechanized equipment. Therefore,the unmanned mining target of the coal mining face could be r eached. The control technology of the powered support,control technology of the coal shearer,video monitoring technology of the coal mining face,remote central controI technology and personnel safety perception technology would be the key technologies of the unmanned mining with the visualized remote interferences. The site appli cation showed that the unmanned mining technology with the visualized remote interferences and the economic and social benefit were excellent. Especially,in the near future,the coal mining face could realize a self suitable intelligent unmanned mining at the primary stage and could provide the basic discovery study on the self suitable intelligent unmanned mining and the robot mining.
