相关申请
本公开是以申请号为202111020213.7，申请日为2021年9月1日，发明名称为“排水抢险车的作业装置和排水抢险车”的中国专利申请为基础，并主张其优先权，该中国专利申请的公开内容在此作为整体引入本公开中。

城市发生内涝灾害后，尤其是高架桥下、立交桥下和地下涵洞等低洼地段因排水不畅造成大面积积水时，需要抢险排水车在桥上或地下涵洞侧方进行排水作业以进行应急救援，这就要求排水抢险车的作业装置能有效地避开桥梁侧方的防护栏、地下涵洞侧方的防护栏或其它障碍物的阻挡，将安装在作业装置靠近车辆尾部处的水泵移送至需要排水的位置，进行排水作业。

本公开实施例的排水抢险车的作业装置中，移送机构安装于转动臂上，排水机构设置于移送机构的第一支架上，在变幅驱动装置的驱动下，转动臂可带动移送机构和排水机构在竖直平面内做变幅运动，在第一移送驱动装置的驱动下，第一支架可进一步带动排水机构沿第一移送方向远离转动臂。在实施应急救援时，上述转动臂和第一支架的复合动作可以为排水机构提供充足的空间以避让较高的防护栏或其它较高的障碍物，无须在开展排水作业之前拆除防护栏或障碍物，利于扩展作业装置的作业范围，提升应急救援的效率。在上述转动臂和第一支架的复合动作的基础上，排水机构 可沿第一支架的长度方向移动至积水区域，在较短的时间内即可开展排水作业。
在一些实施例中，第一移送驱动装置还与排水机构驱动连接，用于驱动排水机构沿第二移送方向移动。其中，第二移送方向为第一支架24的长度方向。在第一移送驱动装置的驱动下，设置于第一支架24上的排水机构不仅可以随第一支架24沿第一移送方向远离转动臂11，还可以相对于第一支架24沿第二移送方向运动，作业装置可以一并执行翻越障碍物的动作和移动排水装置的动作，利于进一步提升应急救援的效率，快速开展排水作业。
在一些实施例中，移送机构还包括第二支架23，第二支架23沿第二移送方向可滑动地设置在第一支架24上，第二移送方向为第一支架24的长度方向。排水机构设置于第二支架23上，可以随第二支架23一同在第一支架24上沿第二移送方向滑动，以到达积水区域。
在一些实施例中，移送机构还包括至少一个连接杆21，至少一个连接杆21的两端分别铰接于第一支架24和转动臂11上。作为第一移送驱动装置的具体形式，第一移送驱动装置包括第一驱动油缸22，第一驱动油缸22的两端分别与第二支架23和转动臂11铰接，用于驱动第一支架24和转动臂11沿第一移送方向相互靠近或远离以及驱动第二支架23相对于第一支架24沿第二移送方向滑动。
在一些实施例中，在设置连接杆21的基础上，移送机构包括至少两个连接杆21，转动臂11、第一支架24和连接杆21组成平行四边形机构。如图2所示，移送机构可以包括两个连接杆21，转动臂11、第一支架24和两个连接杆21组成一个平行四边形机构。根据移送机构的结构稳定性要求和移送机构的尺寸，还可以设置更多的连接杆21，组成多个平行四边形机构。
在一些实施例中，第二支架23包括排水管架231和水泵架232，水泵架232沿第二移送方向可滑动地设置于排水管架231上。排水机构包括水泵30和沿自身长度方向可伸缩的排水管31。排水管31的一端与水泵30连接，另一端与排水管架231连接，水泵30安装于水泵架232上。移送机构还包括第二移送驱动装置，第二移送驱动装置与水泵架232驱动连接，用于驱动排水管架231相对于水泵架232沿第二移送方向滑动，以使排水管31沿自身长度方向伸缩。
根据以上设置，水泵30不仅可以在第一移送驱动装置的驱动下随第二支架23在第一支架24上沿第二移送方向移动，还可以在第二移送驱动装置的驱动下随水泵架232在排水管架231上沿第二移送方向移动并带动排水管31伸缩，从而使水泵30相 对于第一支架24具有更长的移动距离，利于进一步扩展作业装置的作业范围。
在一些实施例中，作为第二移送驱动装置的具体形式，第二移送驱动装置包括第二驱动油缸25，第二驱动油缸25的两端分别与排水管架231和水泵架232连接。
在一些实施例中，作为变幅驱动装置的具体形式，变幅驱动装置包括变幅油缸12。变幅油缸12分别与转动臂11的长度方向的第二端和底座13铰接，用于驱动转动臂11相对于底座13转动，以使转动臂11的长度方向的第二端靠近或远离底座13。

在变幅油缸12的驱动下，转动臂11相对于底座13摆动一定的角度，移送机构和排水机构随转动臂11摆动相同的角度。
若障碍物较高，在第一驱动油缸22的驱动下，两个连接杆21摆动同样的角度，使第一支架24沿第一移送方向远离转动臂11，以将排水机构举升一定的高度，便于排水机构避让障碍物；同时在第一驱动油缸22的驱动下，第二支架23沿第二移送方向滑移并远离第一支架24，使排水机构整体相对于第一支架24滑移一定的距离，水泵30向积水区域移动。
在第二驱动油缸25的驱动下，水泵架232沿第二移送方向滑移并远离排水管架231，使排水管31沿自身长度方向伸长，水泵30进一步远离第一支架24，水泵30进 一步向积水区域移动。
作业装置展开的过程中，转动臂11摆动的角度、连接杆21摆动的角度、第二支架23相对于第一支架22滑移的距离以及水泵架232相对于排水管架231滑移的距离可根据积水区域周围的障碍物的种类和尺寸确定。
水泵30到达积水区域后，开始执行排水作业。
最后应当说明的是：以上实施例仅用以说明本发明的技术方案而非对其限制；尽管参照较佳实施例对本发明进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本发明的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本发明技术方案的精神，其均应涵盖在本发明请求保护的技术方案范围当中。
