Description

一种矿用悬浮单体液压装置
技术领域
本发明涉及采矿设备技术领域，具体为一种矿用悬浮单体液压装置。
背景技术
矿用悬浮单体液压装置是一种开采煤层的支撑设备，具有体积小，使用灵活，支撑可靠的优点，通常是采用外注中性液体进行浮动支撑，但是这种设备还存在不足之处：1、在深层煤层开采时，对外注油泵管路要求高，使用时通常会受到配套管路的影响；2、升柱的支撑采用三用阀闭合进行定位，升柱的复位采用机械弹簧收缩和自重复位，收缩效果差，不容易维护维修；3、升柱体过载时通常使用三用阀进行调控，而三用阀集注液、溢流和回流一体，当三用阀出现问题时，直接会造成不可估量的后果，对三用阀的要求较高，本发明提供一种矿用悬浮单体液压装置。
发明内容
本发明的目的在于提供一种矿用悬浮单体液压装置，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种矿用悬浮单体液压装置，包括油缸、底座、密封盖、升柱体、托架体、储液套和控制盒，所述底座套设在油缸的底部，所述密封盖套设在油缸的顶部，所述储液套套设在油缸上，所述升柱体套设在油缸内，所述托架体套设在升柱体的顶部，所述油缸的底部设置有磁推组合，所述升柱体的顶部内侧套设有磁力阻尼装置，所述升柱体内设置有左回转销和右回转销，所述左回转销上套设有左回转磁板，所述右回转销上套设有右回转磁板，所述储液套内设置有储液腔，所述储液腔内套设有补气塞，所述油缸内设置有回液道、压力腔、聚流槽和液道，所述升柱体内设置有泄压道，所述回液道通过聚流槽和泄压道连接，所述储液腔通过球阀和液道连接，所述磁力阻尼装置包括阻尼柱体和电磁线圈，所述电磁线圈设置在阻尼柱体内，所述阻尼柱体上设置有对流通道，所述磁推组合包括导向滑道、电磁推板和牵引杆，所述电磁推板内设置有电磁绕线，所述电磁推板的底部设置有滚轮和转轴，所述牵引杆的一端通过转轴安装在电磁推板上，所述牵引杆的一端设置有柱塞棒，所述磁推组合通过柱塞棒和压力腔的配合与油缸连接，所述控制盒设置在底座的一侧，所述控制盒上设置有控制按钮。
作为本发明的一种优选实施方式，所述左回转磁板和右回转磁板大小规格相同。
作为本发明的一种优选实施方式，所述密封盖上设置有提手。
作为本发明的一种优选实施方式，所述密封盖和升柱体之间设置有密封圈，所述升柱体和底座之间套设有密封套。

作为本发明的一种优选实施方式，所述控制按钮包括阻尼按钮和导流按钮，所述控制按钮通过电线与电磁线圈和电磁绕线连接。
与现有技术相比，本发明的有益效果是：
1、在储液腔内灌注含有纳米磁性颗粒的碳氢化合物的电磁液，通过向磁推组合上电磁绕线供电产生磁性，磁力将流入到底座内的电磁液并推入到升柱体内，随着升柱体内的电磁液增多，升柱体开始提升进行支撑，无需外部动力源；
2、当升柱体承受负载时，磁力阻尼装置上的电磁线圈通电产生和压力方向垂直的磁场方向，电磁液内的磁性纳米颗粒在磁场的改变排列方向，这些粒子马上会垂直于压力方向来阻碍电磁液在活塞通道内流动，进而实现定位支撑，纳米电磁液温度升高，外置磁场力降低，来控制磁性回流阀重新实现负载平衡来保护自身；
3、当升柱体超载时，升柱体内的电磁液受压后温度会升高，电磁线圈在高温下内部电阻会增大，电流减小从而是磁场强度降低，从而降低对升柱体内电磁液磁粒子的约束，电磁液会通过阻尼柱体上的对流通道进入到泄压道到内，升柱体会下降，当电磁液温度恢复时，磁场强度提高，升柱体停止下降恢复平衡。

作为本发明的一种优选实施方式，所述左回转磁板11和右回转磁板12大小规格相同。
作为本发明的一种优选实施方式，所述密封盖3上设置有提手。
作为本发明的一种优选实施方式，所述密封盖3和升柱体4之间设置有密封圈，所述升柱体4和底座2之间套设有密封套。
作为本发明的一种优选实施方式，所述补气塞14的一端设置有压环31。
作为本发明的一种优选实施方式，所述托架体5的顶部设置有支撑块。
作为本发明的一种优选实施方式，所述控制按钮包括阻尼按钮和导流按钮，所述控制按钮通过电线与电磁线圈21和电磁绕线26连接。
工作原理：将底座2放置在适当位置，然后将控制盒30接通外部电源，由外部电源向设备提供电能，然后在储液套6的储液腔13内注入纳米电磁液，纳米电磁液作为升柱体4浮升的介质，当需要支撑矿井壁时，手动旋松球阀，储液腔13内的电磁液利用其自重通过球阀进入到油缸1的底部，此时手动按下导流按钮，电磁推板24内的电磁绕线26通电产生磁性，由于“同性相斥”原理，纳米电磁液中的磁性粒子在电磁推板24的磁推力作用下向升柱体4内流动，随着升柱体4内电磁液的增多，升柱体4开始相对油缸1向上运动，当上升到一定高度时并承受负载时，关闭球阀并手动再次按下导流按钮电磁绕线26断电，电磁推板24上的磁推力消失，由于左回转磁板11和右回转磁板12相互吸引闭合的阻碍作用，纳米电磁液将停留在升柱体4内，手动按下阻尼按钮，磁力阻尼装置8内的电磁线圈21通电，电磁线圈21通电产生和压力方向垂直的磁场方向，电磁液内的磁性纳米颗粒在磁场的改变排列方向，这些粒子马上会垂直于负载压力方向来阻碍电磁液进入阻尼柱体20内的对流通道22，阻尼柱体20下方的电磁液停止流动，这样就会使升柱体4悬浮在油缸1中，起到浮动支撑的作用，当升柱体4顶部的托架体5过载时，升柱体4内的电磁液受压开始升温，由于温度影响阻尼柱体20上电磁线圈21的电阻，温度越高电阻越大，这样电磁线圈21内电流减少，磁场强度同样减少，这样就会影响电磁液内的磁性纳米颗粒排列，进而会使部分电磁液通过阻尼柱体20上的对流通道22进入到泄压道18内，并通过聚流槽19进入到回液道15内，这样就会降低托架体5的负载，当电磁液的温度复位时，电磁线圈21所产生的磁场强度恢复正常，电磁液内的磁性纳米颗粒重新排列阻碍电磁液体进入到回液道15内，再次实现负载平衡状态。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
