Description

柔性施压快速封堵装备 技术领域
本发明创造属于封堵泄漏领域，尤其是涉及一种柔性施压快速封堵装备。
背景技术
各类危险化学品介质在生产、运输或存储过程中，管道，法兰，罐体设施等逐渐受到介质冲刷、腐蚀、老化以及外界条件(温度、压力)等因素的影响，容易出现本体泄漏、焊缝砂眼的问题，需要及时进行抢修堵漏，以降低财产损失、人员危害和环境污染等。
现有封堵密封技术中，大多采用紧固式堵漏方法，即利用固定夹具、钢带捆扎或钢丝绳的拉紧等方式，使其产生反作用，施加泄漏部位且大于介质本身的压力，实现最终平衡的封堵方法，消除危险化学品介质的泄漏。
然而，由于固定夹具等堵漏方式在实际的泄漏点封堵过程中，存在着制作时间较长，需要现场测绘、设计、适用范围小问题，且封堵时间较长、操作难度大的问题。同时，由于标准管件在制作过程中存在一定的偏差，使得制作的固定夹具不能与泄漏的直管紧密地贴合，严重地影响了封堵的效果。
泄漏点封堵质量的高低取决于着力点的选取。而对于如图1所示的法兰或罐体的根部部位，固定夹具由于体积较大，不但安装困难，还会发生夹具的侧移，从而导致封堵失败。
现有技术中申请号为201511035332.4的中国发明创造专利，采用定位卡对法兰根部泄漏点封堵的方案。在对法兰根部进行封堵前，需要安装一个与管径同规格的定位卡，如果规格不同，则定位效果较差，影响封堵效果，且安装时间比较慢。
发明创造内容
有鉴于此，本发明创造旨在提出一种柔性施压快速封堵装备，以解决安装速度慢的问题。
为达到上述目的，本发明创造的技术方案是这样实现的：
一种柔性施压快速封堵装备，包括封堵定位卡兰，封堵定位卡兰包括相互平行的安装部和固定部，以及连接安装部和固定部的连接部；安装部螺纹连接有封堵定位顶丝，且封堵定位顶丝贯穿安装部；封堵定位顶丝靠近固定部一端转动连接有压块，压块和固定部两者的相邻面上形成有抵接面。
进一步的，所述封堵定位顶丝靠近固定部一端形成有球形座，压块一端开有安装槽，球形座插入安装槽内；安装槽的内壁上开有同轴设置的环形槽，环形槽内套设有卡簧，球形座被卡簧卡在安装槽内。
进一步的，所述压块和固定部两者的抵接面的截面呈弧形。
进一步的，所述压块的抵接面形成有并排设置的摩擦纹。
进一步的，所述固定部的抵接面形成有十字交叉设置的摩擦纹。
进一步的，所述固定部上还有设置有相对于固定部面积较大的封堵头，封堵头靠近压块一侧衬有橡胶制的胶垫。
进一步的，所述封堵定位顶丝远离压块一端沿径向开有通孔，通孔内套设有把手。
进一步的，所述还包括索具带和前索具块；前索具块形成有两个并排设置的前一贯穿孔和前二贯穿孔，索具带绕过管体并遮住泄漏点，索具带两末端分别贯穿前一贯穿孔和前二贯穿孔；前索具块分别在前一贯穿孔和前二贯穿孔处，通过顶丝与索具带紧定螺钉连接；连接部外壁形成有平行于管体轴线的支撑面，前索具块靠近管体一端抵接在支撑面上。
进一步的，所述索具带在泄漏点处缠绕多层密封带。
进一步的，所述索具带上还设有拉紧组件；拉紧组件包括后索具块和拉紧器，拉紧器套设在索具带两个末端外，后索具块通过顶丝固接索具带两个末端，拉紧器夹持在前索具块和后索具块之间。
相对于现有技术，本发明创造所述的封堵装备具有以下优势：
1、可直接应用于直管泄漏封堵，缩短封堵装备的组装时间，提高封堵质量；
2、增加法兰、罐体根部泄漏部位的着力点，为快速、有效地封堵创造条件。
本产品以同向的轨迹运行，进而有效降低各组件的组装时间，进一步缩短封堵过程所使用的时间，完成泄漏点的封堵过程；在各种根部泄漏点封堵时，提供安全、可靠的着力点。

下面将参考附图并结合实施例来详细说明本发明创造。
实施例1：一种柔性施压快速封堵装备，如图2所示，包括封堵定位卡兰1。封堵定位卡兰1包括相互平行的安装部11和固定部12，以及连接安装部11和固定部12的连接部13。
安装部11螺纹连接有封堵定位顶丝14，且封堵定位顶丝14贯穿安装部11。封堵定位顶丝14靠近固定部12一端设置有压块15，封堵定位顶丝14靠近固定部12一端形成有球形座141，压块15一端开有安装槽151，球形座141插入安装槽151内。结合图3所示，安装槽151的内壁上开有同轴设置的环形槽152，环形槽152内套设有卡簧16，且卡簧16套设在封堵定位顶丝14外；卡簧16从环形槽152中凸出，且卡簧16的内径小于球形座141的直径，从而球形座141被卡簧16卡在安装槽151内，且压块15和封堵定位顶丝14转动连接。
压块15和固定部12两者的相邻面上形成有抵接面，压块15和固定部12两者的抵接面的截面呈弧形，且两者的抵接面位于同一柱面上。压块15的抵接面形成有并排设置的摩擦纹，而固定部12的抵接面形成有十字交叉设置的摩擦纹，从而用于夹持住泄漏的管体。固定部12靠近压块15一侧衬有橡胶制的胶垫，以封堵泄漏点6。如果泄漏点6较大，固定部12上还有设置有相对于固定部12 面积较大的封堵头2，通过封堵头2挤压胶垫，以保证密封效果。
封堵定位顶丝14远离压块15一端沿径向开有通孔，通孔内套设有把手142，便于转动封堵定位顶丝14。
这样通过转动封堵定位顶丝14，使压块15和固定部12夹持住管体，并用胶垫封堵管体上的泄漏点6。
实施例2：如图4所示，一种柔性施压快速封堵装备，与实施例1不同之处在于，除了封堵定位卡兰1外，还包括索具带3和前索具块4。
前索具块4形成有两个并排设置的前一贯穿孔和前二贯穿孔，索具带3绕过管体并遮住泄漏点6，索具带3两末端分别贯穿前一贯穿孔和前二贯穿孔。前索具块4分别在前一贯穿孔和前二贯穿孔处，通过顶丝与索具带3紧定螺钉连接，从而前索具块4使索具带3绷紧。索具带3在泄漏点6处缠绕多层密封带，密封带封堵泄漏点6。
连接部13外壁形成有平行于管体轴线的支撑面131，前索具块4靠近管体一端抵接在支撑面131上，从而绷紧索具带3。
为便于安装前索具块4，索具带3上还设有拉紧组件5。拉紧组件5包括后索具块51和拉紧器52，拉紧器52套设在索具带3两个末端外，后索具块51通过顶丝固接索具带3两个末端，拉紧器52夹持在前索具块4和后索具块51之间。拉紧器52为一种中空设置的液压缸，受液压系统的驱动，拉紧器52伸长，同时通过调节顶丝，使后索具块51与索具带3固接，而前锁具块沿锁具带滑移，随拉紧器52的伸长，前索具块4前移并绷紧索具带3，通过顶丝固定前锁具块后依次拆除后索具块51和拉紧器52，完成封堵。
以上所述仅为本发明创造的较佳实施例而已，并不用以限制本发明创造，凡在本发明创造的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明创造的保护范围之内。
