Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a support device for pipeline repair construction using the mechanical spiral winding method. Background Technology

[0002] Traditional pipeline installation and repair methods often face numerous limitations, such as environmental damage from excavation, long construction periods, and disruptions to residents' lives and production caused by water and power outages. Mechanical spiral winding pipe technology, with its unique advantages, offers a new approach to solving these problems. It can be performed even with water present, significantly reducing interference with normal water supply, drainage, or other media transport. Furthermore, the construction process is relatively simple and quick, effectively shortening the construction period and reducing costs. However, the spirally wound steel strip will come into direct contact with existing pipelines during its advancement, causing friction that may damage the newly wound steel strip and affect its quality.

[0003] Therefore, it is necessary to improve the equipment for mechanical spiral winding pipeline construction to significantly reduce the probability of friction between the spiral wound steel strip and the existing pipeline during use, thereby improving the quality of pipeline construction. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a support device for pipeline repair construction using the mechanical spiral winding method, which greatly reduces the probability of friction between the spiral wound steel strip and the existing pipeline during use, thereby improving the quality of pipeline construction.

[0005] The present invention relates to a support device for pipeline repair construction using the mechanical spiral winding method, comprising support members. In use, the support members are placed between the pipeline to be repaired and the new pipeline formed by the mechanical spiral winding method, and several of them are arranged along the axial direction of the pipeline to be repaired.

[0006] Furthermore, the support device also includes a rolling element, which is disposed on the support member along the direction of mechanical spiral winding and forms rolling friction with the new pipe formed by the mechanical spiral winding method.

[0007] Furthermore, the support member is a rectangular frame structure, including two oppositely arranged connecting members I and two oppositely arranged connecting members II. The connecting members I have a set curvature, and the rolling element is sleeved on the connecting members II.

[0008] Furthermore, the contact surface between the connector I and the pipe to be repaired is provided with a friction-enhancing structure.

[0009] Furthermore, the friction-enhancing structure is a serrated structure.

[0010] Furthermore, the rolling element is a roller, and there is a set gap between the roller and the pipe to be repaired.

[0011] Furthermore, the connecting member I has a sheet-like structure, and the upper surface of the roller is higher than the upper surface of the connecting member I.

[0012] Furthermore, there is a gap between the roller and the connecting member I.

[0013] The beneficial effects of this utility model are as follows: The support device for pipeline repair construction using the mechanical spiral winding method of this utility model, by setting a support component between the spiral winding steel strip and the original pipeline, can prevent the spiral winding steel strip from directly contacting the existing pipeline during its advancement, thereby avoiding friction between the winding steel strip and the existing pipeline during the advancement process, greatly reducing the probability of the newly wound steel strip being affected, increasing the advancement speed of the winding steel strip, and improving construction efficiency.

[0019] Figure 1 This is a structural diagram of the support device of this utility model in use. Figure 2 This is a schematic diagram of the support device of this utility model, as shown below. Figures 1-2 As shown: The support device for pipeline repair using the mechanical spiral winding method in this embodiment includes a support member 3. In use, the support member 3 is positioned between the pipeline 1 to be repaired and the new pipeline 2 formed by the mechanical spiral winding method, and several members are arranged along the axial direction of the pipeline 1 to be repaired. Figure 1As shown, the support 3 is positioned between the bottom of the new pipe 2 formed by the mechanical spiral winding method and the pipe 1 to be repaired. This provides support for the inner lining of the new pipe formed by the mechanical spiral winding steel strip (i.e., the new pipe 2 formed by the mechanical spiral winding method), and prevents the new pipe formed by the mechanical spiral winding steel strip from directly contacting the pipe 1 to be repaired (i.e., the original pipe). This also avoids friction between the winding steel strip and the pipe 1 to be repaired during the advancement process, significantly reducing the probability of damage to the winding steel strip and improving the quality of pipe construction.

[0020] In this embodiment, the support device further includes a rolling element 302. The rolling element 302 is disposed on the support member 3 along the direction of mechanical spiral winding and forms rolling friction with the new pipe 2 formed by the mechanical spiral winding method. The rolling element 302 is generally a roller (i.e., a hollow rod-shaped structure). There can be several rolling elements 302, which are disposed on the support member along the winding direction. This allows them to form rolling friction with the new pipe formed by the mechanical spiral winding method of steel strip, which can increase the speed at which the winding steel strip spirally advances along the axial direction of the pipe 1 to be repaired, thereby improving construction efficiency and further reducing the probability of damage to the winding steel strip.

[0021] In this embodiment, the support member 3 is a rectangular frame structure, including two oppositely arranged connecting members I 301 and two oppositely arranged connecting members II. The connecting members I 301 have a set curvature, and the rolling element 302 is sleeved on the connecting member II. Figure 2 As shown, connector II is generally a rod-shaped structure, and after the rolling element 302 is sleeved on connector II, it is welded and fixed to connector I 301. Thus, in use, support 3 can support the new pipe 2 formed by mechanical spiral winding while forming a rolling fit with the new pipe 2 formed by mechanical spiral winding. The middle part of connector II (relative to the middle part of connector II) Figure 1 The curvature of the roller (in the left and right directions) is adapted to the curvature of the pipe 1 to be repaired. The left and right ends of the connector II are raised upwards, so that there is a gap between the roller and the pipe 1 to be repaired, so that the rolling is smooth.

[0022] In this embodiment, the contact surface between the connector I 301 and the pipe 1 to be repaired is provided with a friction-enhancing structure. The friction-enhancing structure is a structure that can increase the friction between the connector I 301 and the pipe 1 to be repaired, thereby allowing the support 3 to be stably supported on the inner wall of the pipe 1 to be repaired. The friction-enhancing structure can be a rubber pad or can be implemented by setting a serrated structure 303 at the bottom of the connector I 301.

[0023] In this embodiment, the friction-enhancing structure is a serrated structure 303. The serrated structure 303 facilitates processing and shaping, and helps to increase the force between the support member 3 and the pipe 1 to be repaired.

[0024] In this embodiment, the rolling element 302 is a roller, and there is a set gap between the roller and the pipe 1 to be repaired, thereby ensuring smooth rolling.

[0025] In this embodiment, the connector I 301 has a sheet-like structure, and the upper surface of the roller is higher than the upper surface of the connector I 301. The sheet-like structure of the connector I 301 facilitates processing, and also... Figure 2 As shown, the upper surface of the roller is higher than the upper surface of the connector II, so that the new pipe 2 formed by the mechanical spiral winding method can directly form a rolling fit with the roller.

[0026] In this embodiment, there is a gap between the roller and the connecting member I301. This facilitates smooth roller rolling. A fixing hole is provided on the connecting member I301 to facilitate the forming and processing of the support member 3.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
