[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0025] In this embodiment, as Figure 1 As shown, the spacing between the limiting plate 9 and the roller body 4 is in the front-to-back direction, and the axial direction of the roller body 4 is in the left-to-right direction.

[0026] refer to Figures 1 to 4 This utility model discloses a non-excavation spiral winding method for repairing pipelines using a profile roller (hereinafter referred to as the profile roller). The roller includes a base 1, with a limiting plate 9 and a roller body 4 spaced apart along the front-to-back direction. The roller body 4 is rotatably mounted on the base 1, and its rotation axis extends along the left-to-right direction. A strip profile 14 is wound around the roller body 4. The upper end of the limiting plate 9 has a profile through hole 10 extending along the front-to-back direction. The size of the profile through hole 10 matches the size of the strip profile 14, and the strip profile 14 passes through the profile through hole 10 and is lowered into the pipeline to be repaired.

[0027] Specifically, in the present embodiment, as shown in Figure 1 , 2 the drum body 4 comprises a middle barrel 12, and the strip-shaped profiles 14 are wound on the middle barrel 12. One drum end cover 13 is fixedly installed at each of the left and right ends of the middle barrel 12, and the drum end covers 13 are coaxially arranged with the middle barrel 12. The outer diameter of the drum end cover 13 is larger than that of the middle barrel 12, and a recess 2 is formed at a position corresponding to each of the drum end covers 13 on the base 1, the recess 2 extends in the front-rear direction, and the size of the recess 2 is matched with that of the drum end cover 13. Specifically, the width of the recess 2 is slightly larger than the thickness of the drum end cover 13, so that the drum end cover 13 can extend into the corresponding recess 2.

[0028] In each recess 2, two supporting rollers 3 are arranged in the front-rear direction at intervals, the supporting rollers 3 are rotatably installed in the recess 2, and the rotation axes of the supporting rollers 3 extend in the left-right direction. The drum end cover 13 extends into the corresponding recess 2 and rests on the corresponding two supporting rollers 3.

[0029] In this way, under the bearing of the supporting rollers 3, the drum body 4 can rotate, each drum end cover 13 is arranged between the two supporting rollers 3, and the two supporting rollers 3 limit the drum body 4 from running out, and at the same time, the support of the supporting rollers 3 can reduce the friction between the drum body 4 and the base 1, so as to ensure the stable and smooth rotation of the drum body 4. At the same time, the drum end cover 13 with a larger outer diameter can also help to prevent the strip-shaped profiles 14 from sliding off the middle barrel 12 during winding, thereby ensuring the stability of the winding and lowering process of the strip-shaped profiles 14.

[0030] Preferably, in the present embodiment, the supporting rollers 3 are H-shaped rollers, the opening width of the H-shaped rollers is matched with the thickness of the drum end cover 13, and the drum end cover 13 rests in the opening of the H-shaped roller. The H-shaped roller enhances the limiting and supporting effect of the drum end cover 13, so as to prevent the drum end cover 13 from shifting left and right during rotation. In other embodiments, the supporting rollers 3 can also be V-shaped rollers or rollers with a square cross section when meeting the actual use requirements.

[0031] Preferably, in the present embodiment, a set of universal wheels 11 is arranged at each of the four corners of the lower end of the base 1, and a brake pad (not shown in the figure) is arranged on each universal wheel 11, so that the entire profile drum device can be moved flexibly on the construction site, and after reaching the designated position, the brake pad is used for fixation, so as to prevent the profile drum from moving accidentally during construction, thereby ensuring the safety and stability of the construction process.

[0032] Preferably, in the embodiment, the limiting plate 9 is slidingly installed on the base 1 along the left-right direction. In this way, the position of the limiting plate 9 can be flexibly adjusted according to actual construction needs, so that when the winding position of the strip-shaped profile 14 on the roller changes or needs to be adjusted due to different specifications of the strip-shaped profile 14 or different construction scenes, the profile through hole 10 can always be adapted to the lowering path of the strip-shaped profile 14 by sliding the limiting plate 9, thereby further enhancing the applicability and adaptability of the device to different working conditions.

[0033] Specifically, in the embodiment, a sliding rail 16 extending along the left-right direction is arranged on the base 1 corresponding to the position of the limiting plate 9. The limiting plate 9 includes an upper plate 91 and a sliding block 8 arranged at the lower end of the upper plate 91. A sliding groove adapted to the sliding rail 16 is arranged on the sliding block 8. The sliding block 8 is clamped on the sliding rail 16 through the sliding groove, so that the limiting plate 9 slides along the sliding rail 16 in the left-right direction.

[0034] Preferably, in the embodiment, the profile roller further includes a driving mechanism 5. The driving mechanism 5 drives the limiting plate 9 to slide on the base 1 along the left-right direction.

[0035] Specifically, as shown in Figure 1 3 In the embodiment, the driving mechanism 5 includes two support plates 6 arranged on the base 1 and disposed on the left and right sides of the sliding rail 16. A driving screw 7 is rotatably installed on the two support plates 6. Specifically, the driving screw 7 extends along the left-right direction, and smooth sections are arranged on the left and right sides of the driving screw 7. The smooth sections are rotatably installed on the support plates 6 through rotary bearings.

[0036] The driving screw 7 is arranged above the sliding rail 16 and spaced apart from the sliding rail 16. The driving screw 7 penetrates the sliding block 8 of the limiting plate 9 and is threadedly connected with the sliding block 8 of the limiting plate 9. One end of the driving screw 7 penetrates the limiting plate 9 on the side and is provided with a driving piece. The limiting plate 9 is limited by the sliding rail 16 to avoid rotation, so that the limiting plate 9 forms a lead screw nut mechanism with the driving screw 7. By rotating the driving piece to drive the driving screw 7, the limiting plate 9 can be driven to slide along the sliding rail 16. On the one hand, the moving distance of the limiting plate 9 can be accurately controlled to adapt to complex construction environments. On the other hand, during the lowering of the strip-shaped profile 14, the driving mechanism 5 can prevent the limiting plate 9 from moving after being moved into position, thereby ensuring the accuracy of the lowering process.

[0037] Specifically, in the embodiment, the driving piece is a handle 15, which is compact in structure and convenient for construction operation. The handle 15 is rotated to drive the driving screw 7 to rotate. In other embodiments, the driving piece can also be a driving motor. The shell of the driving motor is fixed to the support plate 6 on the side, and the rotating shaft of the driving motor is fixedly connected with the driving screw 7. The driving motor is used to drive the driving screw 7 to rotate. ​

[0038] In the embodiment, the strip-shaped section bar 14 is made of one of glass fiber reinforced plastic (GRP), polyester and PVC material, and the strip-shaped section bar 14 made of the appropriate material is wound on the middle barrel 12 for use.

In the continuous laying process, on the one hand, the section bar through hole 10 can preliminarily straighten the wound strip-shaped section bar 14, and on the other hand, the position of the section bar through hole 10 is fixed, so that the strip-shaped section bar 14 away from the middle barrel 12 will not swing left and right.

[0041] In summary, the section bar roller of the utility model is characterized in that the limiting plate 9 is arranged on the base 1, the size of the section bar through hole 10 at the upper end of the limiting plate 9 is matched with the strip-shaped section bar 14, and the strip-shaped section bar 14 is accurately limited by the section bar through hole 10 during the process of being laid from the section bar roller to the pipeline to be repaired. On the one hand, the section bar through hole 10 can preliminarily straighten the wound strip-shaped section bar 14, and on the other hand, the position of the strip-shaped section bar 14 out of the section bar through hole 10 is fixed during the operation, so that the strip-shaped section bar 14 will not swing left and right due to the movement along the axial direction of the roller during the rotation of the section bar roller, the strip-shaped section bar 14 is prevented from swinging and twisting, the effect and precision of the spiral pipe making of the subsequent winding machine are ensured, and the construction quality of the trenchless spiral winding method for repairing the pipeline is improved.
