[0047] Wherein, a drainage pump body 700 is disposed inside the front-end driving mechanism 100 and the rear-end driving mechanism 300 .

[0048] In this embodiment, the front-end driving mechanism 100, the carrying mechanism 200 and the rear-end driving mechanism 300 connected in sequence by the parallel mechanism 400 form a working chassis, and the working chassis is connected by a pipeline through an external control system to control the working chassis. The parallel mechanism 400 is used to enable the overall working chassis to achieve a turning action when encountering a curve in the construction pipeline.

[0050] In one embodiment, the outer side surfaces of the front driving mechanism 100 and the rear driving mechanism 300 are both provided with one or more plugging members 600 adapted to the diameter of the construction pipeline;

[0051] The number of the blocking members 600 on the outer side of the front-end driving mechanism 100 and the rear-end driving mechanism 300 is the same;

[0052] The control system is connected to the blocking member 600 via a pipeline and is used to control the blocking member 600 .

[0053] In this embodiment, the plugging piece 600 is adapted to the diameter of the construction pipeline, so that when the control system controls the filling medium to be transmitted to the plugging piece 600 through the pipeline for expansion, the expanded plugging piece 600 can fit more closely with the inner wall of the construction pipeline, thereby improving the sealing effect.

[0054] In one embodiment, the walking assembly 500 of the front-end driving mechanism 100 and the rear-end driving mechanism 300 is a walking wheel, and the walking wheel is arranged on the outer side of the front-end driving mechanism 100 and the rear-end driving mechanism 300;

At the same time, the pumping end of the drainage pump body 700 in the rear-end driving mechanism 300 is used to pump water from the space between the rear-end driving mechanism 300 and the carrying mechanism 200.

The output end of the parallel mechanism 400 is arranged on the first fixed seat 900 of the front-end driving mechanism 100, and the fixed end of the parallel mechanism 400 is arranged on the second fixed seat 220 of the carrying mechanism 200.

[0071] The single group of pushing hydraulic cylinders 410 is composed of two independent pushing hydraulic cylinders 410;

[0072] The fixed end of the pushing hydraulic cylinder 410 is rotatably connected to the second fixed seat 220 on the carrying mechanism 200 , and the output end of the pushing hydraulic cylinder 410 is rotatably connected to the first fixed seat 900 on the front-end driving mechanism 100 and the rear-end driving mechanism 300 .

A single parallel mechanism 400 is composed of at least two groups of pushing hydraulic cylinder groups. At least two groups of pushing hydraulic cylinder groups in a single parallel mechanism 400 are arranged in an array around the axis of the front-end driving mechanism 100, the carrying mechanism 200 and the rear-end driving mechanism 300.
