The working method of any one of claims 1-9, wherein the process of converting from the running state to the construction preparation state is to control the hydraulic outriggers to extend through the control system to support the ground. , so that the chassis of the dredging truck is in a horizontal support state; then through the control system, the overturning cylinder is controlled to convert the telescopic arm from a horizontal state to a vertical state; 根据窨井井口位置,通过控制系统,控制立柱回转驱动与旋转臂回转驱动旋转,从而带动旋转臂架旋转,通过两个旋转,使伸缩臂垂直处于窨井井口的正上方;According to the position of the manhole wellhead, the control system controls the rotation of the column and the rotation of the rotary arm, so as to drive the rotary boom to rotate, and through the two rotations, the telescopic arm is vertically positioned directly above the manhole wellhead; 通过控制系统控制伸缩油缸的伸缩动作,伸缩臂伸出后,抓斗头部到达窨井底部,通过抓斗油缸杆在抓斗油缸外筒伸出,与抓斗调节杆和抓斗油缸杆铰接的抓斗抓片开始张开,随后通过抓斗油缸杆在抓斗油缸外筒缩进,与抓斗调节杆和抓斗油缸杆铰接的抓斗抓片开始闭合,抓取淤积物;The telescopic action of the telescopic cylinder is controlled by the control system. After the telescopic arm is extended, the head of the grab reaches the bottom of the manhole, and the grab rod extends from the outer cylinder of the grab cylinder, and is hinged with the grab adjustment rod and the grab cylinder rod. The grab piece begins to open, and then retracts in the outer cylinder of the grab cylinder through the grab cylinder rod, and the grab piece hinged with the grab adjustment rod and the grab cylinder rod begins to close to grab the sludge; 通过控制系统控制抓斗油缸杆在抓斗油缸外筒与伸缩油缸进行相反的过程,把污泥带出井口;The control system controls the grab cylinder rod to carry out the opposite process in the grab cylinder outer cylinder and the telescopic cylinder, so as to bring the sludge out of the wellhead; 通过控制系统控制旋转臂回转驱动旋转,从而带动伸缩臂到翻斗车厢的上方;The control system controls the rotation of the rotating arm to drive the rotation, so as to drive the telescopic arm to the top of the dump truck; 通过控制系统控制液压油通过液压卷轴输送给控制抓斗油缸杆在抓斗油缸外筒,抓斗油缸杆在抓斗油缸外筒伸出,抓斗抓片张开,进行卸料;至此一个抓取循环完成,可进入下一个抓取循环,可根据井底情况,通过控制系统控制抓斗旋转器实现抓斗旋转角度,保证井底能抓取干净;The hydraulic oil is controlled by the control system and delivered to the control grab cylinder through the hydraulic reel. The rod is in the outer cylinder of the grab cylinder, the cylinder rod of the grab is stretched out from the outer cylinder of the grab cylinder, and the grab piece is opened for unloading; so far a grab After the grab cycle is completed, the next grab cycle can be entered. According to the bottom hole conditions, the grab bucket rotator can be controlled by the control system to realize the grab bucket rotation angle to ensure that the bottom hole can be grabbed cleanly; 作业完成后,通过控制系统,进行相反操作,控制翻转油缸,使伸缩臂从垂直状态转换为水平状态,控制液压支腿缩回。After the operation is completed, the reverse operation is performed through the control system to control the overturning oil cylinder, so that the telescopic arm is converted from a vertical state to a horizontal state, and the hydraulic outrigger is controlled to retract.
