[0025] The walking mechanism 2 includes four walking wheels 21, a walking drive shaft 22 and a walking drive motor 23. The two walking wheels 21 are rotatably installed on one side below the frame 1, and the walking drive shaft 22 is rotatably installed below the frame 1, that is, two bearing seats are provided below the frame 1, and the walking drive shaft 22 is installed in the bearing seats through bearings. The two walking wheels 21 are coaxially fixedly installed at both ends of the walking drive shaft 22, and the walking drive motor 23 is fixed on the frame 1. The output shaft of the walking drive motor 23 is connected to the walking drive shaft 22 through a connecting assembly 24.

[0026] The coupling assembly 24 includes a first sprocket 241, a second sprocket 242, and a chain 243.

The travel drive motor 23 drives the travel drive shaft 22 to rotate, which in turn drives the travel wheel 21 to rotate, thereby enabling the large-scale pipeline opening device to move within the large pipeline.

[0027] The hole-opening mechanism 3 includes a support column 31 arranged on the frame 1 in the vertical direction, and a mounting seat 32 slidably mounted on the support column 31. There are two support columns 31, and the two support columns 31 are arranged on both sides of the frame 1. A sliding guide rail is arranged on the support column 31 in the vertical direction, and a sliding seat that cooperates with the sliding guide rail is fixed on the mounting seat 32.

[0028] A hole-opening shaft 33 is rotatably mounted on the mounting seat 32. The hole-opening shaft 33 is arranged in the middle position of the mounting seat 32. A thrust roller bearing is provided on the mounting seat 32. The hole-opening shaft 33 is installed in the thrust roller bearing, thereby realizing the rotatable installation of the hole-opening shaft 33 on the mounting seat 32 and enabling the hole-opening shaft 33 to withstand large-load axial forces.

[0029] Reference Figure 2 and Figure 4 As shown, a hole-punching cutter disc 34 is installed at the lower end of the hole-punching shaft 33, and a hole-punching drive motor 35 connected to the upper end of the hole-punching shaft 33 is provided on the mounting seat 32. A flange 36 is integrated at the lower end of the hole-punching shaft 33, and a plurality of flange holes 37 are provided on the circumferential direction of the flange 36. Connecting bolts for threaded connection to the hole-punching cutter disc 34 are provided in the flange holes 37.

[0032] The present application moves in the large pipe through the walking mechanism 2. After moving to the corresponding hole opening position, the inclined top screw 53 is rotated to make the inclined top support foot 54 abut against the inner wall of the large pipe to fix the position. At this time, the lifting mechanism 4 drives the mounting seat 32 to move downward, and makes the hole opening cutter disc 34 abut against the hole opening position of the large pipe. The hole opening drive motor 35 drives the hole opening shaft 33 to rotate, thereby realizing the hole opening cutter disc 34 to open the hole in the large pipe.
