【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/αtanθ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 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 伪 satisfy 1 / 伪 鈮，
