The apparatus as claimed in claim 4, wherein the diameter of the pipe support roller is larger than the radial width of the radial gap, the axial width of the pipe support roller is slightly smaller than the groove width of the inner annular groove and the outer annular groove, and the pipe support roller is partially located in the inner annular groove and partially located in the outer annular groove.
6. The apparatus as claimed in claim 1, wherein a first notch is formed on an inner wall surface of the inner annular groove, a second notch is formed on an outer wall surface of the outer annular groove, and the second notch is located opposite to the first notch, the first pipe fixing member is mounted on the first notch, and the second pipe fixing member is mounted on the second notch.
7. The apparatus according to claim 6, wherein the first and second pipe fixing members each comprise an upper and a lower pressing plates, the upper and lower pressing plates are connected by a bolt, and the distance between the upper and lower pressing plates can be adjusted by screwing the bolt; the lower pressing plate of the first pipeline fixing part is fixed at the bottom of the first notch, and the first notch has a certain depth outwards along the radial direction on the inner wall surface of the inner annular groove so as to be used for penetrating a pipeline into the side surface of the first notch between the lower pressing plate and the upper pressing plate of the first pipeline fixing part; the lower pressing plate of the second pipeline fixing part is fixed at the bottom of the second notch, and the second notch has a certain depth inwards along the radial direction on the outer wall surface of the outer annular groove, so that the pipeline penetrates through the side surface of the second notch to the position between the lower pressing plate and the upper pressing plate of the second pipeline fixing part.
8. The apparatus for guiding self-propelled pipeline in circumferential direction as claimed in claim 2, wherein said inner and/or outer annular grooves are provided with a stopping member for preventing said large roller from passing but not for preventing said pipeline supporting roller from passing, said stopping member being located beside said first pipeline fixing member and on the opposite side of the pipeline penetrating.
9. The apparatus for guiding self-propelled pipeline ring direction as claimed in claim 1, wherein the inner annular groove and the outer annular groove are formed by a plurality of arc-shaped grooves in a butt joint manner.
