【技术实现步骤摘要】
本专利技术涉及一种新型暗杆闸门,属于水利工程中水渠用插板式闸阀
技术介绍
钢闸门通常是用来开启和关闭局部水工建筑物中过水口的活动结构,一般用于用于船坞水泵房,启闭动作比较频繁。传统的暗杆钢闸门为螺母镶在钢闸门门体内上端,启闭机丝杆工作段在最下端刚好与螺母啮合形成丝杆螺母传动副,当钢闸门门体启升打开或下行闭合时,丝杆传动而螺母不动,从而使钢闸门门体上升或下降,实现开合动作。由于丝杆与螺母传动副在水下工作,润滑油容易流失到水中,而且水下加润滑油很不方便,润滑油的流失,造成丝杆与螺母传动副的过早磨损,水中浮渣也容易渗入到螺母传动副中,导致丝杆与螺母传动副之间咬死,闸门无法打开,使用寿命短,铸造门体时需要增加丝杆走道,工艺复杂制造成本高。
技术实现思路
