Abstract

本实用新型涉及煤矿井下综采设备领域,公开了一种刮板机用液压闸盘,其包括:油缸、两个钳臂、制动片和制动盘;所述油缸和制动片铰接在钳臂上,用油缸作为动力实现闸盘的闭合/松开。运用油缸的伸缩实现闸盘的夹紧和松开动作,用液压换向阀来操纵油缸的工作方向,使紧链工作迅速,同时也降低了井下工人的劳动强度。

Description

刮板机用液压闸盘
技术领域
刮板输送机是煤矿井下综采设备,刮板机长时间工作,链条会出现过松现象,从而影响刮板输送机的工作效率,所以必须进行紧链工作。闸盘便是完成紧链工作的关键部件。 
背景技术
现用的闸盘均为手动,属于机械式的,工人操作较费力,更重要的是不能满足现代矿井对高效生产的要求。 
实用新型内容
现有技术采用的手动机械闸盘,通过手动操作钳臂使制动片向内移动,通过摩擦使制动盘停止转动,进而进行刮板机的紧链、掐链工作,采矿工人的劳动强度大、工作效率低。本实用新型提供能够降低工人劳动强度,提高工作效率的闸盘。为了降低井下采矿工人的劳动强度、提高工作效率,本实用新型刮板机用液压闸盘,其包括:油缸、两个钳臂、制动片和制动盘;所述油缸和制动片铰接在钳臂上,用油缸作为动力实现闸盘的闭合/松开。以液压式替代机械式、以液压换向阀控制油缸的运行方向,从而实现闸盘的闭合/松开。 
附图说明
图1为本实用新型刮板机用液压闸盘的示意图; 
图中,1:油缸;2:钳臂;3:制动片;4:制动盘。 
具体实施方式
如图1所示,油缸1及制动片3铰接在钳臂2上,油缸1收缩两钳臂2使制动片3向内移动,通过摩擦使制动盘4停止转动,进而进行刮板机的紧链、掐链工作;当油缸1活塞杆伸出时,制动片3向外移动松开制动盘4,刮板机可进行正常运转。
