【摘要】：為抓捕斷裂或者倒轉(zhuǎn)打滑的輸送帶,從而減少輸送帶斷裂造成的破壞與損失,介紹了一種新型全斷面斷帶抓捕器,闡述了該抓捕器的結(jié)構(gòu)與動(dòng)作原理,并根據(jù)理論力學(xué)基本知識(shí)分析了抓捕過(guò)程,給出了抓捕器實(shí)現(xiàn)斷帶抓捕的條件,并分析了夾持角與摩擦因數(shù)等對(duì)抓捕效果的影響規(guī)律。研究結(jié)果表明:當(dāng)夾持角θ與摩擦因數(shù)α滿足1/α≤tanθ時(shí),抓捕器可形成自鎖,即在結(jié)構(gòu)與輸送帶強(qiáng)度允許范圍內(nèi),抓捕器可以提供足夠大的抓捕力夾持?jǐn)鄮?當(dāng)1/αtanθ時(shí),抓捕器不能形成自鎖,此時(shí)機(jī)構(gòu)存在最大抓捕力,且與配重、夾持角以及摩擦因數(shù)有關(guān),可根據(jù)實(shí)際需求配重調(diào)整等方法實(shí)現(xiàn)抓捕。
[Abstract]:In order to catch the conveyor belt with fracture or reverse slip, so as to reduce the damage and loss caused by the fracture of the conveyor belt, this paper introduces a new type of full-section catcher with broken belt, and expounds the structure and action principle of the catcher. According to the basic knowledge of theoretical mechanics, the process of arrest is analyzed, and the conditions for the arrest of broken belt are given, and the influence of clamping angle and friction coefficient on the capture effect is analyzed. The results show that when the clamping angle 胃 and friction factor 偽 satisfy 1 / 偽 鈮，
