[0002] In the existing technology, when designing the main structure of a public building in a building construction project, a civil air defense basement with a corresponding area needs to be designed. The water and electricity pipes in the civil air defense project are all laid with metal pipes and have a certain explosion-proof function. Among them, most of the large-area pipes are laid in a straight line, while a small part of the pipes need to be bent irregularly according to actual needs. Ordinary elbows cannot meet the actual construction requirements. Considering factors such as cost, construction environment, and pipeline bending requirements, construction workers usually manually bend the pipes, resulting in a waste of human physical strength. Manual bending is not easy to control the bending angle, and it is also easy to cause wrinkles or direct breakage on the inner wall of the pipe. The pipe is damaged during bending, resulting in an increase in construction costs. There are technical problems such as the use of manual processing for pipeline bending considering factors such as cost or irregular pipeline bending requirements, which not only has a large labor intensity but also is not easy to control the bending degree, and there are potential quality hazards in pipeline processing.

[0035] As Figures 1 to 12 shown, a schematic diagram of an embodiment of a pipeline bending tool of the present invention includes a support part, which serves as the core stress-bearing skeleton of the entire pipeline bending tool and can provide sufficient support for other components; a fixing part, which is connected to the support part and is used to fix the pipeline 6 during the bending process of the pipeline 6; a telescopic part 1 that can be rotatably connected to the pipeline 6. The telescopic part 1 is connected to the support part, and the length of the telescopic part 1 can be adjusted to cooperate with the fixing part to achieve the bending process of the pipeline 6.

[0036] In this embodiment, the fixing part includes an arc-shaped support 2 connected to the supporting part, and a groove 21 is formed in the arc-shaped support 2. This embodiment can avoid wrinkles or cracks caused by manual bending by personnel, has a simple structure, and occupies a small space.

[0037] In one embodiment, the number of telescopic parts 1 is one, and the fixing part further includes a fixing component. The fixing component and the telescopic part 1 are respectively arranged on both sides of the arc-shaped support 2. The fixing component is detachably connected to the pipeline 6. When the pipeline 6 is bent, the fixing component and the telescopic part 1 are respectively connected to the pipeline 6. The pipeline 6 contacts the arc-shaped support 2 and the pipeline 6 is arranged in the groove 21. One end of the pipeline 6 can be fixed by the fixing component and the arc-shaped support 2, and the length of the telescopic part 1 can be adjusted to bend the pipeline 6. Preferably, in this embodiment, the fixing component has the same structure as the telescopic part 1. The fixing component can not only be used for fixing one end of the pipeline 6, but also for bending the pipeline 6, that is, the number of telescopic parts 1 is two and they are respectively arranged on both sides of the arc-shaped support 2. In this embodiment, the two telescopic parts 1 can be symmetrically distributed. When small-angle bending of the pipeline 6 is required, only the length of one side of the telescopic part 1 needs to be adjusted to meet the processing requirements; when large-angle bending of the pipeline 6 is required, the lengths of the telescopic parts 1 on both sides can be adjusted in sequence to meet the processing requirements.

[0038] On the other hand, the present invention also provides a pipeline bending method, including the following usage steps:

[0039] Each telescopic part 1 is connected to the pipeline 6. In this embodiment, both ends of the pipeline 6 are respectively connected to the corresponding telescopic parts 1. The length of the corresponding telescopic part 1 is adjusted to move the pipeline 6. The pipeline 6 contacts the arc-shaped support 2 and the pipeline 6 is arranged in the groove 21. The telescopic part 1 can cooperate with the arc-shaped support 2, and the pipeline 6 can be supported by the arc-shaped support 2. The groove 21 and the telescopic part 1 cooperate to play a clamping role, and the length of the telescopic part 1 is adjusted to bend the pipeline 6.

[0040] In this embodiment, the telescopic part 1 is rotatably connected to the supporting part to adjust the angle between the telescopic part 1 and the supporting part. This embodiment can better be applicable to irregular bending of pipelines 6 of different sizes and specifications, meet the arbitrary curvature adjustment within a certain range of pipelines 6 of different lengths or pipe diameters; this embodiment can also be applicable to complex usage environments, has a wide applicability, and is convenient for popularization and application.

[0041] In this embodiment, the telescopic part 1 includes a control member 11 and a telescopic member 12. The telescopic member 12 is rotatably connected to the pipeline 6, the telescopic member 12 is threadedly connected to the control member 11, and the control member 11 is rotatably connected to the support part. By rotating the control member 11, the length of the telescopic part 1 can be adjusted to bend the pipeline 6. Preferably, the telescopic member 12 is disposed within the control member 11. The telescopic part 1 further includes a connecting member 13, and the connecting member 13 is movably embedded within the control member 11 and is rotatably connected to the control member 11; the connecting member 13 is rotatably connected to the support part. Preferably, the connecting member 13 can be hinged to the support part through a rotating shaft 51. The connecting member 13 can not only receive the axial rotation of the control member 11, enabling the control member 11 to rotate itself to adjust the length of the telescopic part 1; the connecting member 13 can also be hinged to the support part, enabling the control member 11 to rotate relative to the support part to adjust the included angle between the telescopic part and the support part. In this embodiment, the stress for bending the pipeline 6 can be converted into axial tension. Through the structural design of threaded connection and by connecting the pipeline 6 to the telescopic member 12 to restrict the rotation of the telescopic member 12, rotating the control member 11 can promote the movement of the telescopic member 12 in the length direction relative to the control member 11, facilitating the adjustment of the length of the telescopic part 1 and providing sufficient axial tension for bending the pipeline 6. A handle 111 is provided on the control member 11 for rotation. The handle 11 facilitates the adjustment of the length of the telescopic part 1, improves the usage efficiency, and reduces the labor intensity.

[0042] In this embodiment, the support part includes a support rod 3 and a reinforcing rod 4. The fixing part and the telescopic part 1 are respectively connected to the support rod 3, and the two ends of the reinforcing rod 4 are respectively connected to the support rod 3 and the fixing part. Preferably, the support rod 3 and the reinforcing rod 4 are hollow inside to reduce the weight of the components. The arc-shaped support 2 is connected to the support rod 3, the reinforcing rod 4 is perpendicularly connected to the support rod 3, the end of the arc-shaped support 2 is connected to the reinforcing rod 4, the middle of the arc-shaped support 2 is connected to the support rod 3, and the fixing part is connected to the support part and forms a symmetric structure with the support rod 3 as the axis. In this embodiment, the arc-shaped support 2 is used as the support groove for bending the pipeline 6. The middle of the arc-shaped support 2 is welded to the support rod 3, and a reinforcing rod 4 is provided between the two ends of the arc-shaped support 2 for reinforcement. The three points can be connected by welding. The reinforcement structure with multiple support points can ensure the structural strength of the arc-shaped support 2. It can not only prevent the arc-shaped support 2 from deforming during long-term use, ensure the service life of the tool, but also provide stable support for the arc-shaped support 2 to ensure the bending processing effect of the pipeline 6. In this embodiment, the control member 11 is rotatably connected to the support rod 3 through the connecting member 13.

[0043] In this embodiment, it further includes a ferrule 5 detachably connected to the pipeline 6, and the telescopic part 1 is rotatably connected to the ferrule 5. Preferably, the ferrule 5 includes a locking component and two oppositely arranged limiting members. The opposite sides of the two limiting members are curved surfaces to adapt to the pipeline 6. The two limiting members are movably connected by the locking component to adjust the distance, so as to realize that the ferrule 5 can be sleeved outside different pipelines 6 and detachably connected to the pipeline 6. The locking component can be an adjusting screw and a nut threadedly connected to the adjusting screw. The ferrule 5 can be rotatably connected to the telescopic part through a connecting shaft 51. Preferably, the ferrule 5 can be rotatably connected to the telescopic member 12 through a rotating shaft 51. This embodiment can bear shear force and ensure the rotating function at the same time.

[0044] The specific usage method of this embodiment is as follows:

[0045] As Figure 10 shown, adjust the relative positions of the arc-shaped support 2 and the two ferrules 5 respectively arranged at the ends of the corresponding telescopic parts 1 so that the three are in a straight line. Specifically, the operator can prevent the telescopic member 12 from rotating through the ferrule 5 while rotating the control member 11 and drive the telescopic member 12 to move telescopically through the threaded force until the lower edges of the two ferrules 5 and the bottom of the groove 21 of the arc-shaped support 2 are flush and in a straight line. Place the pipeline 6 to be bent through one side ferrule 5 and then place it in the groove 21 of the arc-shaped support 2, and then pass through the other side ferrule 5.

[0046] Rotate the corresponding control member 11 to adjust the length of the corresponding telescopic part 1. At this time, the arc-shaped support 2 can be used as the fulcrum in the middle of the pipeline 6, and the ferrule 5 can bend the pipeline 6 under the traction of the telescopic part 1. The middle of the pipeline 6 is limited by the groove 21 to be stuck and remain stationary, and the end of the pipeline 6 is stressed and moves, so as to realize the bending processing of the pipeline 6. In this embodiment, the pipeline 6 can be bent along any tangent line of the arc-shaped support 2; and when one telescopic part 1 is telescoped to bend one end of the pipeline 6, the other telescopic part 1 can cooperate with the arc-shaped support 2 to fix the other end of the pipeline 6. Finally, according to requirements, the bending angle of the pipeline 6 can be finely adjusted to ensure the processing quality and meet the bending processing at any angle within a certain range. As Figure 11 shown, when the pipeline 6 needs to be bent at a small angle, only the length of one side telescopic part 1 needs to be adjusted to meet the processing requirements; or as Figure 12 shown, when the pipeline 6 needs to be bent at a large angle, the lengths of the two side telescopic parts 1 can be adjusted in sequence to meet the processing requirements.

[0047] In this embodiment, the bending stress of the pipeline 6 is converted into axial tension by the telescopic part 1. The threaded adjustment can more accurately control the bending angle of the pipeline 6. With the support and fixation of the arc-shaped support 2, it is ensured that the bending rate of the pipeline 6 meets the requirements, and it can also avoid wrinkles or breaks caused by the influence of manual bending on the inner side of the pipeline 6. It can improve the bending processing efficiency and quality, reduce the material loss rate and save the processing cost, and speed up the construction progress.

[0048] The present invention can reduce the labor intensity of personnel in bending metal pipes 6, avoid the difficult control of the bending degree caused by manual bending, adopt screw rotation control to replace manual bending, and can accurately control the bending angle of the pipes 6. The pipe bending tool has a simple structure, low preparation cost, small occupied space and wide applicability.

[0049] The above has described the embodiments of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
