Mechanical structure of pipeline dredging robot

The invention discloses a mechanical structure of a pipeline dredging robot. The mechanical structure of the pipeline dredging robot comprises a moving mechanism, a platform base, a reamer device and a pumping device, a fixing shaft of a driving wheel set is fixedly connected with a rotating shaft of a motor, the motor drives the driving wheel set to rotate, then a crawler belt, a driven wheel set and a middle wheel set are driven to rotate, and the pipeline dredging robot is driven to walk. By adjusting a telescopic hydraulic rod, the desilting operation requirements of pipelines with different widths can be met; through the automatic adjustment of the telescopic hydraulic rod and the pressure stabilizing and buffering effects of a spring, the joint cleaning operation requirements during working of different pipelines can be met; and the mechanical structure of the pipeline dredging robot can be combined with a displacement sensor, a force sensor, an industrial camera and a hydraulic system to continuously c
