【技术实现步骤摘要】
手控阀限位装置
本技术涉及井下运输设备
,具体涉及一种手控阀限位装置。
技术介绍
现阶段井下运输设备所用的手控阀手柄没有强力的限位装置,驾驶员极易碰到手柄,导致手控阀手柄移动,极不安全,非常容易造成安全事故,给生产带来不便,危及现场施工人员的安全。
技术实现思路
为了解决上述技术问题中的不足,本技术的目的在于:提供一种手控阀限位装置,能够对手控阀手柄进行限位,防止手控阀手柄移动,造成安全事故。本技术为解决其技术问题所采用的技术方案为:所述手控阀限位装置,包括手控阀阀体,手控阀阀体的右侧设置支撑手柄座和阀芯,支撑手柄座上装有手控阀手柄,手控阀手柄的上端设置手球,所述阀芯与手控阀手柄通过连接片相连接,手控阀阀体的上端设置手控阀限位板,手控阀限位板的中部开有滑道,滑道的两侧设置圆孔,手控阀手柄安装在滑道的内侧,手控阀手柄的外侧套装手柄阀滑块,手柄阀滑块与手控阀手柄之间套装弹簧和手柄阀套管,手柄阀套管固定在弹簧与手球之间。驻车时,向上抬起手柄阀滑块,弹簧压缩,手柄阀滑块下部的凸台离开手控阀限位板左端的圆孔,此时,手控阀手柄可自由向前移动,手控阀手柄底部作为支点,位置由A至B,到达B位置,在连接片的带动下将阀芯拉出达到制动作用,此时,将手柄阀滑块放下,弹簧伸展复位,手柄阀滑块下部的凸台进入手控阀限位板中间空槽右端的圆孔内,圆孔给予手柄阀滑块限位作用,手控阀手柄此时便不能再移动位置,起到限位作用。行车时,同样向上抬起手柄阀滑块,弹簧压缩,手柄阀滑块下部的凸台离开手控阀限位板右端的圆孔,此时,手控阀手柄可自由向后移动,位置由B至A,到达A位置后,在连接片的带动下将阀芯推回 ...
