Description

一种漏斗车密封式底门 技术领域
本发明涉及漏斗车密封设备技术领域，具体为一种漏斗车密封式底门。

漏斗车为底开门车辆，通常在车厢底部安装有底门，用于运输散粒货物，待车辆到达目的地后，采用底部卸货的方式将散粒货物卸下。
为了避免散粒物料在运输过程中从底门漏出，通常需要使底门密封。现有技术中，为了使底门密封达到更好的密封效果，一是在底门密封端面增设弹性部件，底门在该弹性部件的作用下虽然能够达到较好的密封效果。但是，弹性部件容易变形、磨损或者老化而失效。
另外一种是从制造工艺上尽量减小这些缝隙，但不能从根本上解决上述问题。
发明内容
本发明的目的在于：提供了一种漏斗车密封式底门，解决了现有漏斗车底门密封不好的问题。
本发明的目的通过下述技术方案来实现：
一种漏斗车密封式底门，包括底门框和底门，还包括滑道，底门滑动设在滑道上，底门框与底门接触贴合，滑道上支撑部的支撑高度沿关闭方向逐渐增高，和/或底门的托举部的托举高度沿开启方向逐渐增高。通过滑道对底门的垫高支撑，或者通过底门自身的垫高托举，实现底门在关闭时向底门框贴近，在开启时向底门框远离，不但能够保证密封贴合，也能减少摩擦方便开启。
进一步的，所述的底门框包括左右的横向底门框，横向底门框之间连接有侧向底门框和横梁，侧向底门框、横向底门框和横梁之间形成漏斗口，底门关闭时对漏斗口密封，底门开启进行卸货。
进一步的，所述的底门包括底门板，底门板滑动设在滑道上，底门板与滑移驱动机构连接。通过驱动机构实现底门板的水平滑移，实现其开合作用。
进一步的，所述的滑移驱动机构包括齿条，齿条设在底门板上，齿条与齿轮啮合，齿轮设在底门轴上，通过底门轴旋转带动齿轮和齿条啮合，实现底门板的传动滑移。同样的，滑移驱动机构也可以采用其它结构类型。
进一步的，所述的底门板上设有两根平行的齿条，左右两条齿条能够保证滑移的同步性和稳定性。
进一步的，所述的滑道的上部设有低支撑部和高支撑部，低支撑部和高支撑部之间的高差为h，底门的下部设有低托举部和高托举部，低托举部和高托举部之间的高差为h。支撑部的高差与托举部的高差相吻合，能够实现补偿式的稳定升高或下降。
进一步的，所述的滑道为辊道，辊道包括左右的托梁，托梁之间设有销轴，销轴上设有旋转的滚轮作为支撑部，以滚轮作为滑道的支撑、滑移部件。
进一步的，所述的左右的托梁之间连接有连接板。
进一步的，所述的滚轮包括第一滚轮作为高支撑部，还包括第二滚轮和第三滚轮作为低支撑部，以高差不同的滚轮形成阶梯状的支撑布置。
进一步的，所述的底门板上设有密封调整板作为高托举部，底门板的下端面作为低托举部，密封调整板的高度为h，以密封调整板作为垫板形成阶梯状的托举布置。
进一步的，所述的底门板上设有至少两根平行的滑道，保证滑移托举的稳定性。
本发明的有益效果：
1、滑道中布置不等高的支撑部，在底门开闭时，通过底门板、密封调整板之间的接触组合，实现底门开启、关闭时与底门框间隙的自动变化。
2、关门时，第一滚轮、第三滚轮接触压紧底门板，底门板与底门框零间隙，对货物完全密封。
3、开门时，第一滚轮脱离底门板，第二滚轮、第三滚轮接触支撑底门板， 底门板与底门框形成间隙，便于开启。
4、底门结构设计简单、合理，提高整车密封性能和使用寿命。

具体实施方式
下面结合具体实施例和附图对本发明作进一步的说明。
参考图1～6所示，一种漏斗车密封式底门，包括底门框1、底门2和滑道，底门2滑动设在滑道上，底门框1与底门2接触贴合，滑道上支撑部的支撑高度沿关闭方向逐渐增高，底门2的托举部的托举高度沿开启方向逐渐增高。
从而在关闭时，由于滑道对底门2的支撑高度不断变高，以及底门2的托举高度不断变高，底门2与底门框1之间的间隙变小直至接触贴合。在开启时， 由于滑道对底门2的支撑高度不断变低，以及底门2的托举高度不断变低，底门2与底门框1之间的间隙变大，减少底门2与底门框1之间的摩擦，方便底门2的开启。
具体的，底门框1包括左右的横向底门框12，横向底门框12之间连接有侧向底门框11和横梁13，侧向底门框11、横向底门框12和横梁13之间形成漏斗口。
底门2包括底门板21，底门板21滑动设在滑道上，底门板21与滑移驱动机构连接。滑移驱动机构包括齿条23，两根平行的齿条23通过螺钉固定在底门板21上，齿条23与齿轮25啮合，齿轮25通过销键连接在底门轴24上，可绕底门轴24中心轴线转动，底门轴24可通过外部动力驱动旋转，带动齿轮25旋转并与齿条23啮合，实现底门板21的前后移动。
底门板21上设有至少两根平行的滑道，保证对底门2滑动支撑的稳定。滑道为辊道3，辊道3包括左右的托梁31，托梁31之间设有销轴32，销轴32的上部设有可旋转的滚轮34作为支撑部，左右的托梁31之间焊接连接有连接板33，将左右的托梁31连接在一起。
支撑部包括低支撑部和高支撑部，第一滚轮341作为高支撑部，等高的第二滚轮342和第三滚轮343作为低支撑部，低支撑部和高支撑部之间的高差为h。底门2的下部设有低托举部和高托举部，底门板21上固定设有密封调整板22作为高托举部，底门板21的下端面为低托举部，低托举部和高托举部之间的高差即密封调整板22的高度为h。
参考图7～9所示，本发明的工作流程：
底门开启过程：开启前，第一滚轮341与底门板21接触，第二滚轮342与底门板21之间存在间隙h，第三滚轮343与密封调整板22接触，底门板21与底门框1贴合无间隙。开启时，底门轴24转动，带动齿轮25同向旋转，齿轮25与齿条23啮合，将转动转换为平动，带动底门板21朝图示右侧移动一定距离l，第一滚轮341与底门板21脱离，第三滚轮343与密封调整板22脱离，底门板21垂向向下移动并与底门框1之间形成间隙h，第二滚轮342、第三滚轮 343与底门板21接触，底门板21继续向右移动，直至打开。
底门关闭过程：关闭前，第三滚轮343与底门板21接触，底门板21与底门框1之间存在间隙h。关闭时，底门轴24转动，带动齿轮25同向旋转，齿轮25与齿条23啮合，将转动转换为平动，带动底门板21朝图示左侧移动，移动过程中，第二滚轮342与底门板21接触，移动到一定位置时，第一滚轮341与底门板21接触，第三滚轮343与密封调整板22接触，底门板21垂向向上移动并与底门框1贴合无间隙，第二滚轮342与底门板21脱离，底门板21继续向左移动，直至关闭。
前述本发明基本例及其各进一步选择例可以自由组合以形成多个实施例，均为本发明可采用并要求保护的实施例。本发明方案中，各选择例，与其他任何基本例和选择例都可以进行任意组合。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
