Description
技术领域
本发明涉及一种电动液控闸阀驱动器,特别是一种机械传动和液压控制的用于矿井下的电液闸阀驱动装置。
背景技术
矿井排水***是矿井安全生产的重要组成部分,排水***通常采用离心式水泵,闸阀是这种***中必不可少的元件。传统的电液闸阀驱动装置主要由电机、液压缸,液压泵和液压阀组成。这种结构组成的电液闸阀驱动装置在应用过程中会出现以下问题:一是应急启闭功能差,例如在检修或遇到突发断电的情况,不能正常工作;二是闸阀开启和关闭速度不便自主调节,容易发生水锤现象。
如公开号为CN200510048257公开的一种《液压可控闸阀》,该闸阀采用液压马达驱动丝杠旋转运动来开闭阀门,但仍然为传统的输出旋转运动,不是直推式输出,未设置应急功能,不能实现启闭双向调速。
再如公开号为CN204828870 U公开的《一种具有应急关阀功能的闸阀电液驱动***及闸阀》,该闸阀电液驱动***包括电机、液压泵、集成控制阀、蓄能器执行油缸和液压油箱构成,采用手动泵进行手动控制,该***虽然设置有应急关阀功能,但仍不能实现闸阀启闭双向调速。
因此,设计一种能够用于应急突发工况的,结构紧凑,能够通过开启和关闭双向调速来消除水锤的闸阀驱动器显得尤为重要。
发明内容
基于上述现有技术存在的具体技术问题,本发明提供一种机电联动液控闸阀驱动器。
上述所提供的一种机电联动液控闸阀驱动器的具体的技术方案如下。
一种机电联动液控闸阀驱动器,包括有防爆电机,液控闸阀及执行器机架;其特征在于:增设有手摇增速箱总成,通过手摇增速箱总成的太阳齿轮与防爆电机的轴连接;增设有双向节流阀,安装于执行器机架的下部内,一端连通有液压油缸;另一端连通有液控单向阀。
所述手摇增速箱总成是在行星架体的一端中心线上设置有太阳齿轮与防爆电机的轴连接,另一端中心线上通过轴承Ⅱ连接有手柄;在行星架体的两侧对称设置有行星齿轮,并通过两个行星齿轮轴与固定在手摇增速箱壳体的内齿轮啮合。
在上述技术方案中,进一步的技术特征如下。
所述两侧对称设置有行星齿轮是绕内齿轮的中心线公转,绕星齿轮轴自转。
所述两个行星齿轮、太阳齿轮、两个行星齿轮轴及内齿轮的齿数分别是29、10、8及48,模数均为2。
所述手摇增速箱总成的增速比是18.5。
所述闸阀打开和关闭的速度是通过双向节流阀调节控制。
实现本发明上述所提供的一种机电联动液控闸阀驱动器,解决了现有电液闸阀在检修和断电等应急工况下能正常工作的问题,也解决了现有电液闸阀在开启和关闭时不能分别调速的问题;将小型手摇增速箱与电机连接在一起,结构紧凑,操作简单可靠;在执行器机架的下部内置有双向节流阀,实现了打开和关闭分别调速;该结构有效地避免了液控闸阀发生水锤的现象,进一步提高了闸阀应用的安全性和稳定性。

具体实施方式
下面结合附图对本发明的具体实施方式作出进一步的说明。
实施一种机电联动液控闸阀驱动器,该驱动器包括液控闸阀1,防爆电机2,执行器机架3,手摇增速箱总成4和双向节流阀5,其构成是将该手摇增速箱总成4与防爆电机2通过内六角螺钉19连接固定,其手摇增速箱总成4包括手摇增速箱壳体6,轴承Ⅰ7,骨架油封8,轴承Ⅱ9,行星架体10,行星齿轮11,行星齿轮轴12,行星架板13,止动环14,轴用挡圈15,键16,太阳齿轮17,内齿轮18,内六角螺钉19,沉头螺钉20和垫套21。其中,该手摇增速箱总成4是在行星架体10的一端中心线上设置有太阳齿轮17与防爆电机2的轴固定连接,另一端中心线上通过轴承Ⅱ9固定连接有手柄;在行星架体10的两侧对称设置有行星齿轮11,并通过两个行星齿轮轴12与固定在手摇增速箱壳体6的内齿轮18啮合。
在上述实施方案中,执行器机架3的下部内装有双向节流阀5,如附图3和附图6所示,该双向节流阀5一端连通有液压油缸,另一端连通有液控单向阀,在工作时,该驱动器能够调节液控闸阀的打开和关闭速度,打开和关闭时间均大于60秒,有效地消除了两种状态下水锤事故的发生。
在上述实施方案中,当液控闸阀处于断电情况下,手摇增速箱总成1开始参与运行。通过转动手摇柄,使得行星架体10转动,然后带动行星齿轮轴12转动,内齿轮18不转,行星齿转轴12转动带动同轴行星齿轮11,而后驱动太阳齿轮17,增速比调为18.5即可,该行星齿轮11的手摇增速箱总成4的结构具有传动级数少,效率高,输出输入同轴,传动比大的特点。
本发明上述实施的一种机电联动液控闸阀驱动器,主要目的是针对煤矿井下、大型工厂、石油化工等管道液体需要控制的场合,特别是在维修、断电等应急情况下需要电液闸阀稳定打开与关闭的场合。
上述实施的一种机电联动液控闸阀驱动器的实现方法如下。
如附图1至附图5所示,当处于断电的情况下,手摇增速箱总成4开始参与运行。通过转动手摇柄,使得行星架体10转动,然后带动行星齿轮轴12转动,内齿轮18不转,行星齿转轴12转动带动同轴的行星齿轮11,而后驱动太阳齿轮17,最终太阳齿轮17同电机轴一起转动,实现手摇方式驱动防爆电机2。
在电液闸阀的工作状态中,开启和关闭电液闸阀时均会产生水锤现象,但关闭时更严重,在双向节流阀5能够对电液闸阀的打开和关闭两种状态分别进行控制速度,使得电液闸阀的打开和关闭时间均大于60秒,从而有效地消除了两种状态下的水锤现象发生,该双向节流阀中小孔节流阀芯是可更换的,孔径不同,对应不同的速度,因此操作方式为通过更换不同的小孔节流阀芯来调节速度。
