压裂井场中，当压裂橇出现故障或需要维护、保养时，需要将压裂橇移动至维修、维保工位进行对应操作。当前，人工拖动压裂橇，将压裂橇移送至对应的工位。然而，上述移动压裂橇的方式需要大量人力，从而，造成了压裂橇移送不方便，增加人员劳动力等问题。
发明内容
本申请实施例的目的是提供一种移动式压裂橇、压裂井场及压裂橇的维保方法，能够解决当前方式导致压裂橇移送不便，且增加劳动力等问题。
为了解决上述技术问题，本申请是这样实现的：
本申请实施例提供了一种移动式压裂橇，该移动式压裂橇包括：压裂橇本体和多个分布于压裂橇本体底部的行走装置；
每个所述行走装置包括安装架和行走机构，所述安装架连接于所述压裂橇本体的底部，所述行走机构设置于所述安装架，所述行走机构用于带动所述压裂橇本体移动。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例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。

下面结合附图，通过具体的实施例及其应用场景对本申请实施例进行详细地说明。
参考图1至图6，本申请实施例公开了一种移动式压裂橇，应用于压裂井场，移动式压裂橇可以在压裂井场内移动，从而方便维修、维保。
所公开的移动式压裂橇包括压裂橇本体100和多个行走装置200，多个行走装置200分布于压裂橇本体100的底部，通过多个行走装置200可以对压裂橇本体100起到支撑作用，与此同时，多个行走装置200启动后还可以带动压裂橇本体100移动，从而可以将压裂橇本体100移送至预设位置，如，将出现故障或需要维保的压裂橇本体100移送至维修、维保工位，或者将维修或维保后的压裂橇本体100移送至压裂井场的作业工位(即下述的压裂工位)，从而可以实现压裂橇本体100的自由移动。可选地，压裂橇本体100可以包括底橇120和设置于底橇120的压裂泵130等，需要说明的是，压裂橇本体100的部分结构及其工作原理均可参考相关技术，此处不作详细阐述。
基于上述设置，本申请实施例中，通过行走装置即可带动压裂橇本体自由移动，以便于使压裂橇能够按照实际需求进行移动。相比于采用人工拖动压裂橇的方式，本申请实施例中的移动式压裂橇无需增加人力，而是在需要移动时直接通过多个行走装置带动压裂橇本体移动至预设位置，从而大大提高了压裂橇本体移动的便捷性，与此同时，不会额外增加人员劳动力，并且降低了劳动强度。
为了使压裂橇本体100在移动状态和作业状态(即，非移动状态)之间进行状态切换，本申请实施例中，每个行走装置200还可以包括升降驱动机构220。其中，安装架210活动连接于压裂橇本体100，升降驱动机构220设置于压裂橇本体100，且升降驱动机构220的驱动端与安装架210连接，行走机构230设置于安装架210。基于此，在升降驱动机构220的驱动作用下，安装架210可以相对于压裂橇本体100活动，并同步带动行走机构230运动，以实现行走机构230的升降，使行走机构230能够与支撑表面接触，或者脱离支撑表面，其中，支撑表面可以是地面，还可以是其他任何用于放置或行走压裂橇本体100的表面。
基于上述设置，在移动式压裂橇处于移动状态的情况下，多个行走装置200均可以与支撑表面接触，以使压裂橇本体100脱离支撑表面，具体为，多个行走装置200下降并与支撑表面接触，随着多个行走装置200持续下降，在反作用力的作用下，将压裂橇本体100顶起，从而压裂橇本体100脱离支撑表面；而后启动多个行走装置200，通过多个行走装置200可以携带压裂橇本体100进行自由移动，以便于将压裂橇本体100移送至预设位置。
在移动式压裂橇处于非移动状态(即，作业状态)的情况下，多个行走装置200均可以脱离支撑表面，具体为，当不需要移送压裂橇本体100时，多个行走装置200均处于回缩状态，此时，多个行走装置200均脱离支撑表面，在没有多个行走装置200的支撑作用时，压裂橇本体100落至支撑表面，此种情况下，压裂橇本体100不会移动，从而可以保证压裂橇本体100作业时的稳定 性。
本申请实施例中，在升降驱动机构220的驱动作用下，可以通过安装架210带动行走机构230上升而脱离支撑表面，并将压裂橇本体100放置于支撑表面，或者下降而将压裂橇本体100从支撑表面顶起，从而可以实现压裂橇本体100在移动状态和非移动状态之间的切换，既可以保证移动状态下对于压裂橇本体100移送的便捷性，又可以保证非移动状态下压裂橇本体100稳定作业。
相比于采用叉车、吊车等设备拖动压裂橇的方式，本申请实施例中的移动式压裂橇无需额外使用其他设备拖动压裂橇本体100，而是在需要移动时直接通过多个行走装置200托起压裂橇本体100并带动压裂橇本体100移动至预设位置，从而大大提高了压裂橇本体100移动的便捷性，与此同时，不会额外增加人员劳动力。
参考图3、图5和图6，在其中一些实施例中，安装架210可以相对于压裂橇本体100摆动，以通过摆动形式实现安装架210的局部升降，从而带动行走机构230进行升降。
示例地，安装架210具有相背设置的第一端和第二端，其中，安装架210的第一端与压裂橇本体100转动连接，以使安装架210可以相对于压裂橇本体100进行摆动；升降驱动机构220的驱动端与安装架210的第二端活动连接，以通过升降驱动机构220带动安装架210摆动；行走机构230设置于安装架210的第一端与第二端之间。
可选地，压裂橇本体100的底部可以设置固定座114，固定座114开设有通孔，相应地，安装架210的第一端可以设置带通孔的连接耳，连接耳的通孔与固定座114的通孔中穿设销轴，以便于实现安装架210相对压裂橇本体100摆动。
基于上述设置，在升降驱动机构220的驱动作用下，安装架210的第二端可以随着升降驱动机构220的驱动端升降，从而使整个安装架210相对于压裂橇本体100进行摆动，与此同时，行走机构230随着安装架210进行摆动，在 摆动过程中，行走机构230可以上升而脱离支撑表面，或者下降而接触支撑表面，进而可以使移动式压裂橇在行走状态和非行走状态之间切换。
当然，还可以是，安装架210的第一端与压裂橇本体100转动连接，升降驱动机构220的驱动端与安装架210的中部区域活动连接，行走机构230设置于安装架210的第二端，此种方式同样可以实现行走机构230的升降，以实现移动式压裂橇在行走状态和非行走状态之间切换。
考虑到安装架210相对于压裂橇本体100摆动，而升降驱动机构220的驱动端沿升降方向(即，竖直方向)移动，由此，安装架210与驱动端各自之间的运动可能会产生干涉，导致行走机构230无法进行升降。
为防止出现运动干涉，主要参考图5，一些实施例中，升降驱动机构220的驱动端与安装架210的第二端中的一者设有长孔222，另一者设有铰接轴240，其中，铰接轴240可转动且可移动地设置于长孔222中。基于此，在升降驱动机构220的驱动端升降的过程中，铰接轴240可以在长孔222中转动，并且在长孔222中进行位置调整，从而可以有效避免安装架210与升降驱动机构220的驱动端之间产生运动干涉，保证了行走机构230的正常升降。
一种较为具体的实施例中，长孔222可以设置于升降驱动机构220的驱动端处，铰接轴240可以设置于安装架210的第二端，以便于使行走机构230升降。
在其他一些实施例中，安装架210滑动连接于压裂橇本体100，并相对于压裂橇本体100可升降，从而可以通过升降形式实现安装架210的整体升降，以带动行走机构230进行升降。
可选地，压裂橇本体100的底部可以设置沿升降方向延伸的滑道，安装架210的局部设有滑动结构，滑动结构滑动设置于滑道中。如此，在升降驱动机构220的驱动作用下，安装架210可以整体升降，并同步带动行走机构230升降，从而实现移动式压裂橇在行走状态和非行走状态之间的切换。
参考图5和图6，在一些实施例中，升降驱动机构220可以包括可充放气 的气囊221，该气囊221的一端固定于压裂橇本体100，气囊221的另一端与安装架210连接，在气囊221充气时体积膨胀，从而可以对安装架210产生挤压作用，以通过安装架210推动行走机构230，使行走机构230挤压支撑表面，在反作用力的作用下，压裂橇本体100被顶起；在气囊221放气时体积收缩，具体可以采用抽气泵对气囊221进行抽气，从而可以使行走机构230上升，此时在重力作用下，压裂橇本体100下降，以便于使压裂橇本体100落至支撑表面。
可选地，气囊221可以为柱状气囊，且柱状气囊的轴线与升降方向平行，当然，还可以是其他形状，本申请实施例中对于气囊221的形状不作具体限定。
本申请实施例中，行走装置200可以包括履带式行走机构、辊轮式行走机构、爬行式行走机构、滚子式行走机构和滑靴式行走机构中的至少一种。上述各种方式的行走机构230均可以实现压裂橇本体100的自由移动。此处需要说明的是，履带式行走机构、爬行式行走机构、滚子式行走机构和滑靴式行走机构各自的具体结构均可以参考相关技术，此处不作详细阐述。
另外，行走装置200可以采用电驱动、液压马达驱动或气动马达驱动，以为行走提供稳定的驱动力。
下面将对辊轮式行走机构的具体结构进行详细阐述。
参考图3和图4，在一些实施例中，行走机构230可以包括可转动的辊轮231，辊轮231的转轴连接于安装架210。具体地，安装架210可以包括第一侧板211、第二侧板212、第一连接板213和第二连接板214，其中，第一侧板211和第二侧板212沿第一方向间隔设置，第一连接板213和第二连接板214各自分别连接于第一侧板211与第二侧板212之间，并沿第二方向间隔设置，第一连接板213位于安装架210的第一端，第二连接板214位于安装架210的第二端。其中，第一方向与第二方向相互垂直。此处需要说明的是，第一方向可以平行于压裂橇本体100的移动方向，第二方向可以是压裂橇本体100的移动方向的左右方向，另外，升降方向可以是压裂橇本体100的上下方向，如此， 第一方向、第二方向及升降方向两两垂直。进一步地，辊轮231的转轴与第一侧板211及第二侧板212分别连接，且辊轮231位于第一连接板213与第二连接板214之间。
基于上述设置，通过第一侧板211、第二侧板212、第一连接板213和第二连接板214共同将辊轮231围设在内部，从而可以对辊轮231起到防护作用，以便于防止外部环境对辊轮231的转动造成干扰，进而保证了辊轮231的正常转动；另外，采用辊轮231的形式，在一定程度上还可以适当增大行走机构230与支撑表面的接触面积，从而可以提高压裂橇本体100移动的稳定性。
可选地，如图4所示，行走机构230还可以包括行走驱动件232、减速机233和联轴器234，其中，行走驱动件232的输出端与减速机233的输入端连接，减速机233的输出端与联轴器234连接，联轴器234与辊轮231的转轴连接。可选地，行走驱动件232可以为电机。基于上述设置，通过行走驱动件232输出行走驱动力，经过减速机233的减速增扭作用，可以提高行走机构230的行走能力，通过联轴器234将减速机233的输出端与辊轮231的转轴传动连接，以便于传输动力。如此，行走驱动件232依次通过减速机233和联轴器234带动辊轮231转动，从而可以实现压裂橇本体100的行走。
继续参考图4，为了固定行走机构230，安装架210还可以包括固定框架215，该固定框架215固定于第一侧板211，减速机233固定于固定框架215，联轴器234可转动地穿过固定框架215。基于此，可以通过固定框架215将减速机233固定至安装架210，从而既可以实现动力的传输，又可以保证行走机构230的正常升降。
为了调节移动式压裂橇的方向，在一些实施例中，移动式压裂橇还可以包括多个转向装置(图中未示出)，多个转向装置与多个行走装置200一一对应连接，且多个转向装置均连接于压裂橇本体100的底部。基于此，通过转向装置可以使行走装置200相对于压裂橇本体100进行旋转，从而改变行走装置200的朝向，在多个转向装置的作用下，多个行走装置200可以同步转动，且各自 的转动参数均相同，进而可以使压裂橇本体100按照预设轨迹行走，以使压裂橇本体100能够被移送至预设位置。
此处需要说明的是，转向装置的具体结构及其转向原理均可以参考相关技术，此处不作详细阐述。
考虑到在设置转向装置的情况下，压裂橇本体100容易随意转向，造成压裂橇本体100随意移动。基于此，移动时压裂橇还可以包括多个第一锁紧装置(图中未示出)，多个第一锁紧装置与多个转向装置一一对应连接，且第一锁紧装置用于对相应的转向装置进行锁紧或解锁。其中，在多个第一锁紧装置均处于锁紧状态下，多个转向装置则无法继续转动，此时与多个转向装置分别连接的多个行走装置200则无法转动，进而无法实现转向；在多个第一锁紧装置均处于解锁状态下，多个转向装置可转动，此时，与多个转向装置分别连接的多个行走装置200可以进行转动，以便于使压裂橇本体100转向。
此处需要说明的是，第一锁紧装置的具体结构及其工作原理均可参考现有技术，此处不作详细阐述。
考虑到压裂橇本体100在进行压裂作业过程中，其需要固定不动。基于此，移动时压裂橇还可以包括多个第二锁紧装置，多个第二锁紧装置与多个行走机构230一一对应连接，且第二锁紧装置用于对相应的行走机构230进行锁紧或解锁。其中，在多个第二锁紧装置均处于锁紧状态下，多个行走机构230均被锁定而无法运动，使得压裂橇本体100无法移动，从而可以保证压裂作业过程中压裂橇本体100的稳定性；在多个第二锁紧装置均处于解锁状态下，多个行走机构230均可以运动，此时压裂橇本体100可以通过多个行走机构230进行移动，以便于进行维保。
此处需要说明的是，第二锁紧装置的具体结构及其工作原理均可参考现有技术，此处不作详细阐述。
参考图5和图6，为了安装多个行走装置200，本申请实施例中，压裂橇本体100的底部可以设有多个支撑架110，多个支撑架110与多个行走装置200 一一对应连接，如此，通过每个支撑架110对应安装每个行走装置200。
在一些实施例中，每个支撑架110可以包括第一支撑型材111、第二支撑型材112和固定支撑板113，其中，第一支撑型材111与第二支撑型材112间隔设置，固定支撑板113连接于第一支撑型材111与第二支撑型材112之间；安装架210活动连接于第一支撑型材111及第二支撑型材112中的至少一者，升降驱动机构220固定于固定支撑板113。
可选地，第一支撑型材111和第二支撑型材112均可以为工字型钢等。
当安装架210相对于压裂橇本体100摆动时，安装架210可以与第一支撑型材111或第二支撑型材112转动连接；当安装架210相对于压裂橇本体100升降时，安装架210可以与第一支撑型材111及第二支撑型材112分别滑动连接。
基于上述设置，可以使安装架210相对于压裂橇本体100相对运动，如，摆动或升降移动等，并且保证升降驱动机构220固定的牢固性和稳定性。
基于上述设置，本申请实施例还公开了一种压裂井场，所公开的压裂井场包括多个压裂工位，每个压裂工位设有压裂橇。如此，通过每个压裂工位的压裂橇可以分别进行压裂作业，以满足作业需求。
除此以外，压裂井场还可以包括变压变频器、线缆、管汇、防护板等结构，其中，线缆可以与每个压裂橇连接，以便于为压裂橇供电，并且还可以传输信号，以便于实现对压裂橇的控制；变压变频器用于为压裂井场提供变压变频功能，以满足压裂需求；管汇与每个压裂橇连接，以通过管汇为压裂橇输送液体，并通过压裂橇对液体进行加压，以满足压裂要求；防护板为压裂井场的防护构件，其可以围设在压裂作业部件之外，以起到防护作用。
在一些实施例中，压裂橇可以包括上述移动式压裂橇，此种情况下，当压裂橇需要离开压裂井场时，如，需要到达维保工位进行维保，可以通过行走装置200携带压裂橇本体100从压裂工位移出压裂井场，并移动至维保工位，以进行维保作业；当维保结束后，再次通过行走装置200携带压裂橇本体100从 维保工位移动至压裂工位，以便于继续在压裂工位进行压裂作业。
在另一些实施例中，压裂橇可以包括固定式压裂橇，即，未设置行走装置200，此种情况下，当压裂橇需要离开压裂井时，如，需要到达维保工位进行维保，可以借助外部的移送设备对压裂橇进行移送，以将压裂橇从压裂工位移送至维保工位进行维保；当维保结束后，再次通过移送设备将压裂橇从维保工位移送至压裂工位进行压裂作业。其中，上述移送设备可以是叉车、吊车等设备。
本申请实施例还公开了一种压裂橇的维保方法，应用于上述压裂井场中，所公开的压裂橇的维保方法可以包括：
确定压裂井场内需要维保的压裂橇；
切断与需要维保的压裂橇连接的管汇及线缆；
将需要维保的压裂橇移出对应的压裂工位，并移送至维保工位进行维保操作；
将维保后的压裂橇移入对应的压裂工位；
将管汇及线缆与维保后的压裂橇连接；
启动维保后的压裂橇进行压裂作业。
进一步地，将需要维保的压裂橇移出对应的压裂工位，包括：
通过压裂橇的行走装置200使压裂橇在压裂工位与维保工位之间移动；
或者，借助外部的移送设备使压裂橇在压裂工位与维保工位之间移动。
下面将以移动式压裂橇为例详细阐述维保过程：
根据压裂井场工作需求识别出需要维护保养的压裂橇，如，根据压裂井场的控制系统中记录的每个压裂橇的使用时间来确定是否到达维保时间，当到达维保时间后，则可以向该压裂工位的报警装置发送信号，以提示进行维保。而后，控制压裂井场停止供作，并关闭管汇的总阀门，切断压裂井场总电源；远程控制机器人的机械手将与需要维保的压裂橇连接的高低压管汇、线缆等与井场系统断开；控制需要维保的压裂撬所在的压裂工位周围的防护滑动门滑动开 启；远程控制行走装置，通过行走装置带动压裂橇本体从压裂工位移动至维保工位；控制防护滑动门滑动关闭，压裂井场正常开启作业，同时需要维保的压裂橇在维保工位进行维护保养。
待压裂橇维保完成后，控制压裂井场停止工作，关闭管汇总阀门，切断总电源，控制相应的压裂工位处的防护滑动门开启，远程控制维保完成的压裂橇从维保工位返回至压裂工位，控制防护滑动门滑动关闭，远程控制机器人的机械手将维保后的压裂橇再次与高低压管汇、线缆等进行连接；压裂井场重新开启总阀门、接通总电源，压裂井场重新开机作业。
基于上述过程，可以实现对压裂井场中的压裂橇的维保作业，以延长压裂橇的使用寿命。
综上所述，本申请实施例可以通过多个行走装置200实现压裂橇本体100的自由移动，以便于将压裂橇本体100移送至预设位置，并且还可以实现压裂橇本体100在移动状态和非移动状态之间的切换，既可以保证移动状态下对于压裂橇本体100移送的便捷性，又可以保证非移动状态下压裂橇的稳定作业。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
