【技术实现步骤摘要】
巷道阻车器
本技术涉及一种煤矿机械领域,尤其涉及一种巷道阻车器。
技术介绍
运煤车在倾斜的巷道中时常会出现溜车、失控、下滑等现象,而现有的阻车器等装置存在缺陷,如阻挡住了运煤车,但是运煤车上的煤矿等由于惯性会散落继续下滑,阻车安全性能低,阻车效果差等缺陷。
技术实现思路
本技术的目的是提供一种巷道阻车器,在阻车的同时能够有效的防止煤炭散落继续下滑,安全性能高、效果好。为实现上述目的,本技术采用的技术方案为:一种巷道阻车器,其特征是:两个支撑柱、两个支座Ⅲ分别固定安装在轨道底层上且分别位于轨道两侧,支撑柱上设有限位挡板,支撑柱顶端面上安装支座Ⅰ,前支管底端与支座Ⅰ之间铰接,前支管内设有圆槽,限位柱尾端连接在后支柱上,后支柱尾端安装在挡车板上,限位柱套接在圆槽内,弹簧一端安装在圆槽最底端,弹簧另一端安装在后支柱上,弹簧套在圆槽内,限位柱位于弹簧内;前支管外侧安装支座Ⅱ,伸缩油缸两端分别与支座Ⅱ、支座Ⅲ铰接,初始状态挡车板与轨道底层平行,伸缩油缸伸缩带动前支管、挡车板围绕支座Ⅰ转动。所述伸缩油缸收缩时,挡车板垂直于轨道底层,挡车板高度大于运煤车高度。所述限位挡板能够阻挡前支管向左侧转动。本技术的优点效果在于:初始状态下伸缩油缸伸长,挡车板与轨道底层平行,支撑柱、前支管、后支柱垂直于轨道底层,此时运煤车正常通过巷道;当出现溜车时,伸缩油缸收缩带动前支管、挡车板围绕支座Ⅰ转动,直到挡车板垂直于轨道底层,挡车板将运煤车挡住,能够有效的防止煤炭散落继续下滑,安全性能高、效 ...
