Technical Field

[0001] This utility model belongs to the field of cement pipe production technology, specifically referring to a cement pipe internal and external repair device. Background Technology

[0002] Cement pipes are prefabricated pipes made from cement and steel reinforcement, utilizing the principle of centrifugal force.

[0021] In some embodiments,

[0022] like Figure 1 As shown, a cement pipe internal and external repair device includes a hydraulic lifting assembly 1, an inner diameter telescopic rod 2, a first internal and external repair assembly 3, and a second internal and external repair assembly 4. The inner diameter telescopic rod 2 is connected to the lower part of the hydraulic lifting assembly 1. A rotary motor 5 is provided between the hydraulic lifting assembly 1 and the inner diameter telescopic rod 2. The first internal and external repair assembly 3 is provided at one end of the inner diameter telescopic rod 2, and the second internal and external repair assembly 4 is provided at the other end of the inner diameter telescopic rod 2.

[0023] like Figure 2 As shown, the hydraulic lifting assembly 1 includes a hydraulic device 11 and a hydraulic lifting rod 12. The hydraulic device 11 is equipped with a hydraulic lifting rod 12, and the bottom of the hydraulic lifting rod 12 is connected to a telescopic rod 2 with a fixed inner diameter.

[0024] like Figure 3 As shown, the first internal and external repair assembly 3 includes a first internal repair rod 31, a first internal repair brush 32, a first external repair rod 33 and a first external repair brush 34. The first internal repair brush 32 is provided at the lower part of the first internal repair rod 31, and the first external repair brush 34 is provided at the lower part of the first external repair brush 34.

[0025] like Figure 3 As shown, the first inner repair brush 32 and the first outer repair brush 34 are positioned opposite each other, with the first inner repair brush 32 in contact with the inner wall of the cement pipe and the first outer repair brush 34 in contact with the outer wall of the cement pipe.

[0026] like Figure 4 As shown, the second inner and outer repair assembly 4 includes a second inner repair rod 41, a second inner repair brush 42, a second outer repair rod 43, and a second outer repair brush 44. The second inner repair brush 42 is provided at the lower part of the second inner repair rod 41, and the second outer repair brush 44 is provided at the lower part of the second outer repair brush 44.

[0027] like Figure 4 As shown, the second inner repair brush 42 and the second outer repair brush 44 are positioned opposite each other, with the second inner repair brush 42 in contact with the inner wall of the cement pipe and the second outer repair brush 44 in contact with the outer wall of the cement pipe.

[0028] like Figure 3 and Figure 4 As shown, one end of the inner diameter telescopic rod 2 is connected to the first inner repair rod 31, and the other end of the inner diameter telescopic rod 2 is connected to the second inner repair rod 41. A first wall thickness telescopic rod 35 is provided between the first inner repair rod 31 and the first outer repair rod 33, and a second wall thickness telescopic rod 45 is provided between the second inner repair rod 41 and the second outer repair rod 43. The distance between the first inner repair rod 31 and the first outer repair rod 33 is adjusted by the first wall thickness telescopic rod 35 so that the first inner repair brush 32 contacts the inner wall of the cement pipe and the first outer repair brush 34 contacts the outer wall of the cement pipe.

[0029] In this invention, when repairing the inner and outer walls of a cement pipe, the length of the inner diameter telescopic rod 2 is adjusted to accommodate the inner diameter of the current model of cement pipe. Then, the first wall thickness telescopic rod 35 and the second wall thickness telescopic rod 45 are adjusted to accommodate the wall thickness of the current model of cement pipe. This allows the first inner repair brush 32 to contact the inner wall of the cement pipe, the first outer repair brush 34 to contact the outer wall of the cement pipe, the second inner repair brush 42 to contact the inner wall of the cement pipe, and the second outer repair brush 44 to contact the outer wall of the cement pipe. Then, the hydraulic device 11 and the rotary motor 5 are started, causing the first inner and outer repair components 3 and the second inner and outer repair components 4 to rotate and move up and down. The rough and granular areas on the inner wall of the cement pipe are smoothed and repaired by the first inner repair rod 31 and the first inner repair brush 32 moving up and down and rotating. The rough and granular areas on the outer wall of the cement pipe are smoothed and repaired by the first outer repair rod 33 and the first outer repair brush 34 moving up and down and rotating. This completes the repair of the inner and outer walls of the cement pipe.
