具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例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作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。
下面结合图1-图4描述本申请的一种移动泵站。该移动泵站包括：泵站本体、行走装置1和第一信号收发单元3。
其中，泵站本体，泵站本体包括伸缩部件2和控制伸缩部件2伸缩的第一阀体，伸缩部件可以具有用于工人握持的手柄。泵站本体能提供具有一定压力和流量的液压动力和气压动力。在本实施例中，采用液压动力驱动方式，在泵站本体通过液压油提供液压动力，此时伸缩部件2采用液压油缸，液压油缸具有伸出和缩进的功能。此液压油缸采用手持式，便于工人持拿液压油缸进行拆装销轴的工作。为了工人使用方便，相较于之前采用体积相对较小，重量相对较轻的液压油缸。在伸缩部件2采用液压油缸时，液压油缸连接有第一阀体，第一阀体中阀芯的开度，决定流过该第一阀体液压油的压力和流量。在采用泵体提供液压动力情况下，该第一阀体可采用电磁换向阀，这样便于操控第一阀体内的阀芯的开度。
行走装置1，行走装置1设于泵站本体的底部，用于驱动泵站本体行进。行走装置1可以采用轮式或者履带式。有时工程机械的施工环境较为 恶劣，在遇到雨水天气，路面泥泞情况下，轮式行走装置会造成使用的不便。由于履带式行走结构，能提供较大的抓地力。此处行走装置1选用履带式进行说明。行走装置1一般包括底盘结构及履带行走结构，底盘结构用来支撑并与泵站本体连接，履带行走结构安装在底盘结构的侧面。履带行走结构一般包括有履带架、驱动轮、导向轮、托链轮、支重轮、履带板和马达。驱动轮、导向轮、托链轮和支重轮转动安装在履带架上。驱动轮连接有马达，此处马达选用液压马达，通过马达和减速机带动驱动轮转动，实现多个履带板环绕履带架转动。一般通过液压油驱动履带行走结构。通过履带行走结构的转弯、直线行走实现泵站本体在施工场所移动。应当理解的是，依据实际需要，行走装置1也可以采用其他形式。
第一信号收发单元3，第一信号收发单元3分别与行走装置1、第一阀体信号连接，第一信号收发单元3用于接收和发送指令，根据指令控制相应的结构进行动作，例如第一信号收发单元3可以向行走装置1发出直线行走的指令，行走装置1在接收到第一信号收发单元3发出的指令，会做出相应的直线行走动作。第一信号收发单元3也可以通过控制第一阀体中阀芯的开度，控制伸缩部件2的伸缩动作。第一信号收发单元3可通过有线连接方式(如通过电线连接)，接收指令、发出指令，也可以通过无线连接方式接收指令、发出指令。此处以第一信号收发单元3通过无线连接方式，实现可被遥控为例进行说明。第一信号收发单元3用于接收遥控指令并依据遥控指令控制行走装置1和第一阀体的工作状态。第一信号收发单元3主要接收遥控装置的遥控指令，并将该指令相应发送给移动泵站的对应部件，以实现移动泵站遥控操作。具体地，该移动泵站的遥控指令主要包括前进、后退和转弯等行进指令以及泵站油缸的伸缩指令，行走装置1和伸缩部件2依据相应的指令进行动作。
进一步地，本实施例的移动泵站设有油箱4、液压油油箱、发电机、发动机5、电源、设备操作面板、扬声器和车斗7、泵体等。油箱4储存燃油，油箱4上的加油口朝向外侧设置，便于加注燃油。油箱4等结构固定安装在一个固定框架12上。固定框架12为多个长条杆状、或管状结构，使用焊接成等连接方式，构成一体结构，用于安装动力结构、供回油机构等，行走装置安装于固定框架12的底部。此固定框架12可直接安装在底 盘结构上。当然，固定框架12与底盘结构之间也可以增加回转轴承类装置，实现固定框架12可相对底盘结构旋转。发动机5消耗燃油，用于为泵站提供动力。图2中未示出液压油油箱安装位置，液压油油箱用于存储伸缩部件2所需使用的液压油以及行走装置1行走驱动用所需的液压油。泵体在图中未示出，通过泵体移动液压油油箱内的液压油通过第一阀体至伸缩部件2，使得伸缩部件2伸出，伸缩部件2内的液压油也可以回到液压油油箱，形成液压回路。发动机5分别给行走装置1和伸缩部件2输送动力。
电源为24V蓄电池6，发动机5启动后通过发电机为蓄电池6蓄电，蓄电池6通过配电箱为泵站上的各个传感器、控制器以及发动机5点火提供电能。设备操作面板上具有多种仪表盘8和操作按钮，仪表盘8主要用于将安装在移动泵站上的各类传感器采集到的示数以及报警信息显示出来，如燃油箱中的燃油的油位，蓄电池6内的剩余电量等。操作按钮通过面板安装在固定框架12上，也可以将操作按钮直接固定在固定框架12上。固定框架12外侧通过螺钉可拆卸连接覆盖件，覆盖件为板状结构，覆盖件用于隔离杂物，防止杂物落在动力机构或供回油机构上。固定框架12上有一侧未安装覆盖件，便于观察和后期修理动力机构与供回油机构。覆盖件上开设有若干条形散热孔。
通过操作按钮可以直接控制行走装置1的直线行走、转弯等动作控制，也可以控制伸缩部件2的伸缩动作。动力机构包括发动机5、蓄电池6、起动机等结构，提供动力，发动机的启动与停止控制原理，在此细述。供回油机构包括液压油油箱、油泵、阀组，其与动力机构连接，发动机带动泵转动，从而向供回油机构提供动力。油泵泵出的液压油经管路至阀组，然后至第一阀体，最后进入伸缩部件2内，使得伸缩部件2动作。油泵泵出的液压油经管路至阀组，然后至第二阀体或第三阀体，最后至行走装置1上的马达。
此处阀组采用四联阀组，也可以使用六联阀，在此不做限定。通过阀组进行液压分流。第一阀体、第二阀体、第三阀体采用集成阀体，集成有换向阀及溢流阀，第一阀体、第二阀体、第三阀体均可被信号控制动作。
在第一阀体与伸缩部件2之间设置有快速接头，即液压油从第一阀体 经过，然后通过快速接头，最后至伸缩部件2。通过设置快速接头，在不需要使用伸缩部件2的伸缩功能，将移动泵站作为一个提供液压动力的结构。即通过快速接头，将液压油接入另外需要液压油的装置，如具有其他功能的液压油缸。
以便在移动泵站有人状态下可以提供观测和检查条件。扬声器也可以由第一信号收发单元3的相应指令进行控制，也即可以通过遥控的方式使得移动泵站进行鸣笛。车斗7设于泵站本体的后端，车斗7为顶部开口结构，可放置杂物。为了便于将车斗7中装载的销轴及其他使用工具倒出，车斗7中在履带沿直线行走方向的一侧面成斜面设置，与此同时，位于车斗7斜面下方，行走装置1中的履带行走结构中的履带架倾斜设置。
该移动泵站主要实现伸缩部件2是伸缩功能，以辅助工人高效拆装销轴等部件。因为在大型工程机械上的销轴等零部件重量较重，依靠人力搬运此类物件，较为浪费人力，及工人的工作时间。通过车斗7实现搬运物品的功能，减轻工人工作的强度，避免浪费工人的精力，降低工作效率。
进一步，在拆装场地有些杂物会影响施工，可在移动泵站的前端安装推铲10结构。推铲10通过连接部件11与车斗7可拆卸连接，推铲10也可与行走装置1可拆卸连接。连接部件11采用杆状、或块状结构，推铲10的一侧上通过安装两个连接部件11与车斗7连接。此推铲10的开口朝向泵站的前端。此处设泵站在车斗7倾斜的一侧为前方，发动机、油箱所在的一侧为后端。
再进一步，在移动泵站后端、固定框架12上安装踩踏板9，此踩踏板9可供人站立，使得工人可以随着泵站的移动而移动，即移动泵站具有移动工人的功能。踩踏板9，具有使用、非使用状态，在使用状态下，用于承载使用者或者物品。踩踏板9与固定框架12采用销轴连接方式连接，在固定框架12或销轴处安装限位部件，用于限制踩踏板9在一定角度范围内活动，限位部件采用块体、柱状等结构。在不用踩踏板9时，将踩踏板9翻转至垂直地面的位置。使用时，将踩踏板9放下，使得踩踏板9的上表面大致与地面呈平行，这样能使得使用者站立的更平稳。
操作面板上设置的操作按钮中，其中有具有控制第一阀体中阀芯开度的按钮，即工人可以通过控制该按钮实现控制伸缩部件2的工作状态。也 具有控制行走装置1前进、后退、转弯等功能的按钮。即移动泵站可以通过工人站在泵站上操作泵站的动作，工人也可以通过具有收发遥控信号的控制终端控制泵站的动作。
在车斗7顶端靠近发动机的一侧焊接固定座13，在固定座13顶端焊接两个夹持部件14(如图5所示)，此夹持部件14成半圆环形。将伸缩部件2放入两个夹持部件14的开口结构内，夹持部件14可对伸缩部件提供夹持力。夹持部件14一般采用弹性材料制成，如橡胶、塑料等具有弹性的材料。通过提供夹持力，用于防止伸缩部件2从夹持部件14上脱落。
夹持部件14，安装在固定座13顶端，可用于夹持伸缩部件；
夹持部件14具有弧形开口，在伸缩部件中部分位于弧形开口内时，夹持部件14可提供加持力，用于避免伸缩部件从弧形开口内脱落。
本申请提供的一种移动泵站，通过在泵站上设置信号收发单元，通过遥控的方式对移动泵站的行进和泵站油缸进行控制，使得拆装工人能在以泵站为中心一定范围内，控制泵站行走操作，提高泵站在拆装场地被使用的灵活性，便于多个工人之间相互配合，提高拆装销轴的施工效率。

在其中一个实施例中，行走装置1还包括：第二阀体和第三阀体。第二阀体设置于第一履带轮的驱动油缸；第三阀体设置于第二履带轮的驱动油缸；第一信号收发单元3分别与第二阀体和第三阀体信号连接，用于控制第二阀体和第三阀体的启闭状态。在本实施例中，第二阀体和第三阀体采用电磁比例阀，由第一信号收发单元3发出的指令控制第二阀体和第三阀体的启闭以及开度大小，通过第二阀体控制进入第一履带轮的驱动油缸的液压油的流量和压力，通过第三阀体控制进入第二履带轮的驱动油缸的液压油的流量和压力，从而控制第一履带轮和第二履带轮的转动速度，进而带动履带本体实现移动泵站的前进、后退和转弯。
在其中一个实施例中，行走装置1还包括：第一速度传感器、第二速度传感器和整车控制器。其中，第一速度传感器设于第一履带轮，用于监测第一履带轮的转速；第二速度传感器，第二速度传感器设于第二履带轮，用于监测第二履带轮的转速；整车控制器(Vehicle control unit，简称：VCU)，第一速度传感器、第二速度传感器、第二阀体和第三阀体均与整车控制器信号连接，整车控制器用于接收第一速度传感器和第二速度传感器采集到的的数据并据此调整第二阀体和第三阀体的开度。通过速度传感器分别监测左右履带轮的转速，并将采集到的信息传输回VCU，由VCU进行左右履带轮转速的校正。例如，当移动指令是前进时，此时左右履带轮应保持转速一致，VCU接收到速度传感器采集的转速信息后，进行判断后，相应调整第二阀体和第三阀体的开度，使得左右履带轮的转速保持一致，避免前进跑偏，完成前进校正。
在其中一个实施例中，行走装置1还包括：第一压力传感器、第二压力传感器、第一流量传感器和第二流量传感器。其中，第一压力传感器设置于第一履带轮的驱动油缸；第二压力传感器设置于第二履带轮的驱动油缸；第一流量传感器设置于第一履带轮的驱动油缸；第二流量传感器设置于第二履带轮的驱动油缸；第一压力传感器、第二压力传感器、第一流量传感器和第二流量传感器分别与整车控制器信号连接。在本实施例中，采用压力传感器和流量传感器分别监测进入左右履带轮的驱动油缸的液压油的压力和流量并将采集结果发送至VCU，VCU基于收集到的数据进行行车判断和调节。

通过以上实施例的多种传感器对移动泵站进行监测，采集到的数据可以体现在泵站内部的仪表盘8上，也可以通过第一信号收发单元3将采集到的数据发送至遥控装置上，通过显示屏进行显示。
