搅拌车快开人孔盖
本技术属于搅拌车
,具体涉及一种搅拌车快开人孔盖。
技术介绍
搅拌车罐体人孔主要用于:1、人员进出罐体内检查维修,2、遇到紧急情况需尽快将罐体人孔盖板打开,并将商用混凝土在最短的时间内排出。否则,商用混凝土凝固在罐体内至罐体报废。现有的搅拌车罐体人孔盖采用周圈多个螺栓固定,打开人孔需将多个螺栓全部松开卸掉才能将人孔盖板打开,费力且用时较长。
技术实现思路
本技术的目的是提供一种搅拌车快开人孔盖,解决目前的人孔盖采用周圈多个螺栓固定,打开人孔需将多个螺栓全部松开卸掉才能将人孔盖板打开,费力且用时较长的问题。本技术搅拌车快开人孔盖,包括环形的座圈,座圈顶部边缘处固定有回转支撑,座圈的顶部通过多个锁紧螺栓固定有用于封闭座圈中心孔的盖板,锁紧螺栓设置有不少于5个,盖板顶部中间转动连接有杠杆,杠杆另一端通过销轴与回转支撑转动连接,盖板上设置有多个供锁紧螺栓滑动的滑槽,多个滑槽关于盖板的中心圆形阵列,滑槽沿着顺时针的一端连接有供锁紧螺栓的螺头部脱出的脱出孔,即脱出孔的直径大于锁紧螺
