为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
以下结合附图,详细说明本申请各个实施例公开的技术方案。
如图1所示,本申请实施例提供的固井设备100,包括:柱塞泵10、液压传递组件20、第一分动箱70、变速箱60和底盘发动机30。液压传递组件20设置于柱塞泵10与第一分动箱70之间,第一分动箱70连接于变速箱60与液压传递组件20之间,变速箱60连接于第一分动箱70与底盘发动机30之间,底盘发动机30用于输出动力,底盘发动机30输出的所述动力经由所述变速箱60、所述第一分动箱70、所述液压传递组件20传递至所述柱塞泵10。
相比相关技术中,柱塞泵10需要由额外设置的台上发动机驱动,本申请实施例中,柱塞泵10由底盘发动机30输出的动力驱动,进而不需要在固井设备100上额外设置台上发动机,不仅减轻了100的重量,且固井设备100的输出功率更适用于低压力、小排量的工况下,解决了相关的固井设备100在低压力、小排量的工况下重量太大且功率不匹配的问题。
此外,实际应用中,固井设备100仍可以设置有台上发动机,但是台上发动机的选用较小的功率,从而较适用于低压力、小排量的工控;但是这种改进对固井设备100的减重相对有限。
图2至图5示意出了固井设备100的结构示意图。当然,如图3所示,底盘发动机30是设置于固井设备100中车体自带的发动机,底盘发动机30所输出的动力能够驱动固井设备100的行驶轮。
而且,相关技术中通常采用传动轴连接于第一分动箱70和柱塞泵10之间,传动轴作为转动件需要有足够的尺寸才能满足寿命要求,而且转动轴通常不能弯曲还需要配置配套的防护部件,导致传动轴在固井设备100上占据大量的空间且大幅增加固井设备100的重量。本申请实施例在第一分动箱70与柱塞泵10之间设置有液压传递组件20以传递动力,液压传递组件20可以弯曲设置以灵活布置,因此以液压传递组件20替代至少部分传动轴,可以在一定程度上了减轻固井设备100的重量和体积的目的。
液压传递组件20可以包括液压泵和液压马达,液压泵与液压马达之间可以柔性连接。该液压泵连接于第一分动箱70与液压马达之间,以驱动液压马达,液压马达连接于液压泵 与柱塞泵10之间。
其中,第一分动箱70可以包括一个输入多个输出,且多个输出的动力分配可以相同也可以不同。
其中,液压传递组件20的组数可以至少为两组,例如两组、三组、四组、五组及以上等。在传递相同动力的情况下,相比只设置一组液压传递组件20,液压传递组件20设置成多组后,可以将每组液压传递组件20的体积减小,从而可以更加灵活地的布置多组较小体积的液压传递组件20,进一步减小固井设备100的体积。当然,部分实施例中,液压传递组件20的组数也可以只有一组。在一种实施方式中,每一组液压传递组件20包括一个液压马达和一个液压泵;当然,部分实施例中,每一组液压传递组件20中液压马达和液压泵的数量也可以不做限定,以能够实现利用液压传递动力为宜。
固井设备100还可以包括合力器40,该合力器40连接于各液压传递组件10与柱塞泵10之间,以将各液压马达输出的动力合并传递至柱塞泵10上。其中,液压泵可以为闭式液压泵。如图1中给出了两组液压传递组件20的示意图,其中,第一液压泵21与第一液压马达23为一组液压传递组件20;第二液压泵22和第二液压马达24为一组液压传递组件20。在一种实施方式中,液压传递组件20的组数至少两组,则合力器10可以连接各液压传递组件20,换言之,可以连接所有液压传递组件20,即连接所有组的液压传递组件20中的液压泵。
其中,合力器40可以包括动力输入口和动力输出口,动力输入口的数量可以等于或大于液压传递组件20的组数并连接液压马达,动力输出口可以连接柱塞泵10。
在液压传递组件20中可以包括流量调节阀,流量调节阀设置于液压泵上,能够调节液压传递组件20的传动部。该流量调节阀可以为节流阀,或其他能够控制液压泵流量的阀门。
在一种实施方式中,合力器40可以是第二分动箱41,该第二分动箱41的输出口作为合力器40的动力输入口,该第二分动箱41的输入口作为合力器40的动力输出口。则第二分动箱41的动力输出口的数量应不少于液压传递组件20的组数。
实际应用中,液压传递组件20的数组可以多于两组,则除了上述第一液压泵21与第一液压马达23为一组液压传递组件20;第二液压泵22和第二液压马达24为一组液压传递组件20之外;还可以包括第三液压泵、第三液压马达、第四液压泵、第四液压马达、第五液压泵和第五液压马达等等。当然,此时对应的,合力器40的动力输入口的数量不少于液压传递组件20的组数,才能够顺利地将各组液压传递组件20传递的动力合并于合并器40上用于驱动柱塞泵。
固井设备100还可以包括转动轴50,该转动轴50连接于合力器40和柱塞泵10之间。当然,若合力器40(第二分动箱41)与柱塞泵10之间距离足够近,则也可以不设置转动轴50。此外,转动轴50可以具有一定的伸缩量,以适应柱塞泵10与合力器40之间的距离波动。需要说明的是,虽然本申请提出的固井设备100中设置了转动轴50,但是由于液压传递组件20的设置,该转动轴50相比上述相关技术中的传动轴的尺寸更小,进而相比相关技术中的传动轴的体积和重量也更小。
本申请实施例的固井设备100中,参图3和图4,还可以包括底盘80,底盘发动机30设置于底盘80上。底盘80上可以设置两条相互平行的大梁81,大梁81从车头延伸至车尾,底盘80上还可以包括与大梁81相互垂直的多条副梁82。液压传递组件20可以部分或全部设置在该两条大梁81之间,进而充分利用底盘80上的空间。即液压泵和液压马达可以均设置在相邻的大梁81之间。
在一种实施方式中,变速箱60连接于底盘发动机30的输出端。变速箱60可以与底盘发动机30一体设置在底盘80上,也可以分体设置在底盘80上。
本申请实施例中,底盘80可以包括位于车头部分的底盘(参图5)和位于车身部分的底盘(参图3)。
第一分动箱70设置于变速箱60与液压传递组件20之间。显然,第一分动箱70可以连接各液压传递组件20的液压泵。由此,底盘发动机30输出的动力依次经过变速箱60、第一分动箱70后、液压传递组件20、第二分动箱41、转动轴50之后进入柱塞泵10。
本申请实施例中,由于液压传递组件20的设置,可以保证柱塞泵10工作稳定。而且,可以借助液压传递组件20上的流量调节阀实现传动比的调整,进而实现对柱塞泵10的工作功率的无极调节。因此,底盘发动机30也可以以额定功率运行,而不会对其工作功率进行调节。显然,也可以不用对变速箱60进行调节。
此外,固井设备100还可以包括其他的液压元件,这些液压元件连接于第一分动箱70的输出端,液压元件由底盘发动机所输出的动力驱动。即,底盘发动机所输出的动力可以用于传递动力至离心泵、搅拌***等其他的执行器件上。
以上介绍了本申请的固井设备100的一种实施方式,以下结合具体示例说明一种固井设备100。
如图2所示,该固井设备100由柱塞泵10、转动轴50、第二分动箱41、第一液压马达23、第二液压马达24、第一液压泵21、第一分动箱70、第二液压泵22、变速箱60组成。
通过底盘设置在车上的变速箱60上的第一分动箱70取力驱动第一液压泵21和第二液 压泵22,由第一液压泵21和第二液压泵22分别驱动第一液压马达23和第二液压马达24,并将两个液压马达安装在一个两口第二分动箱41上,第二分动箱41的两个输出口作为作为动力输入口,第二分动箱41的输入口作为动力输出口,动力输出口连接传动轴50,通过传动轴50进而驱动柱塞泵10。该示例实现了由两个液压马达共同驱动一个柱塞泵10的目的。两个液压泵驱动两个液压马达有效利用了空间,同时可以进一步采用更多个的液压泵驱动更多个马达并采用多口第二分动箱41驱动方式驱动柱塞泵10。
图3和图4示出了包括车体在内的固井设备100的结构示意图,示意出上述柱塞泵10、液压传递组件20、底盘发动机30等部件在车体上的相对位置。
此外,如图5所示,固井设备100还可以包括高压管路91、操作平台92、混浆罐93、计量罐94、液压油箱95及其他附件等。
本申请上文实施例中重点描述的是各个实施例之间的不同,各个实施例之间不同的可选特征只要不矛盾,均可以组合形成可能的实施例,考虑到行文简洁,在此则不再赘述。
以上所述仅为本申请的实施例而已,并不用于限制本申请。对于本领域技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等,均应包含在本申请的权利要求范围之内。
