[0041] As Figure 1-7 shown, as the core component for achieving flow diversion in the pipeline system, the forming process of the tee pipe has long faced technical bottlenecks such as low welding efficiency of the inner wall of the pipe and complex operations. At present, the traditional process mainly relies on manual or semi-automatic equipment to complete the welding of the branch pipe and the main pipe. Especially when operating inside a narrow pipeline, there are significant defects. However, since conventional welding requires the operator to enter the pipeline or use an external device to position the welding torch 12, it results in high labor intensity and potential safety hazards. At the same time, due to the limitation of the pipeline space by the operator, it is difficult to ensure the welding angle and the uniformity of the weld seam.

[0042] To solve the technical problems of low welding efficiency and complex operation in the inner wall welding of tee pipes in pipeline engineering, the present application provides a forming device for tee pipes used in pipeline engineering, including a welding module and a motion module. The welding module includes a housing 11 and a welding torch 12. The housing 11 is in a disc-shaped structure, and the welding torch 12 is arranged on one side thereof to rotate around its central axis. The welding torch 12 performs telescopic movement through a telescopic rod 13. The motion module includes rollers 21 and a driving component. There are multiple groups of rollers 21, which are arranged in a circular array along the central axis of the housing 11 on the housing 11 and are rotatably connected to the housing 11. The driving component includes a bidirectional gear ring 221 and a driving motor 222. There are multiple driving motors 222, which are arranged in a circular array around the central axis of the bidirectional gear ring 221 and are meshed with the inner side of the bidirectional gear ring 221 through driving gears. Each group of rollers 21 is provided with a pair, and they are respectively fixed at both ends of a driven tooth rod, and the driven tooth rod is meshed with the outer side of the bidirectional gear ring 221.

[0043] Through the combination of the welding module and the motion module, the device realizes the welding operation on the inner wall of the pipeline. The welding torch 12 in the welding module can rotate around the central axis and perform telescopic movement through the telescopic rod 13, so as to flexibly perform the welding operation. The rollers 21 and the driving component in the motion module cooperate with each other, enabling the device to move to the position where welding is required inside the pipeline. The rollers 21 are arranged in a circular array along the central axis of the housing 11, making the movement of the device inside the pipeline more stable and accurate. The driving component drives the rollers 21 to rotate through the cooperation of the bidirectional gear ring 221 and the driving motor 222, thereby realizing the movement of the device. The multiple driving motors 222 are arranged in a circular array, ensuring the stable operation of the device. Through the mutual cooperation of these technical features, the problems of low welding efficiency and complex operation in the inner wall welding of tee pipes in pipeline engineering are solved.

[0044] In pipeline engineering, the low welding efficiency and complex operation of the inner wall of tee pipes have always been a difficult problem. Traditional welding processes mainly rely on manual operation or semi-automatic equipment, which not only increases the labor intensity but also poses safety hazards. Especially inside narrow pipelines, it is difficult for manual operation to ensure the welding angle and the uniformity of the weld seam. To solve these problems, the inventor designed a new device, which realizes automatic and efficient welding operations through the combination of a welding module and a motion module.

[0045] The welding module includes a housing 11 and a welding torch 12. The housing 11 is in a disc-shaped structure, and the welding torch 12 can rotate around the central axis of the housing 11 and perform telescopic movement through a telescopic rod 13. The motion module includes rollers 21 and a driving component. The rollers 21 are arranged in a circular array along the central axis of the housing 11 and are rotatably connected to the housing 11. The driving component includes a bidirectional gear ring 221 and a driving motor 222. The multiple driving motors 222 are arranged in a circular array and are meshed with the inner side of the bidirectional gear ring 221 through driving gears, thereby driving the rollers 21 to rotate and enabling the device to move inside the pipeline.

[0046] The welding torch 12 in the welding module performs telescopic movement through the telescopic rod 13, and can flexibly adjust the welding position. The rollers 21 and the drive assembly in the movement module cooperate with each other, enabling the device to move smoothly and precisely within the pipeline to the position where welding is required. Through the mutual cooperation of these technical features, the device can automatically complete the welding operation on the inner wall of the tee pipe within the pipeline, improving the welding efficiency and simplifying the operation process.

[0047] For example, the welding torch 12 in the welding module can rotate around the central axis and perform telescopic movement through the telescopic rod 13, thereby flexibly performing the welding operation. The rollers 21 in the movement module are arranged in a circular array along the central axis of the housing 11, making the movement of the device within the pipeline more stable and precise. The drive assembly drives the rollers 21 to rotate through the cooperation of the bidirectional gear ring 221 and the drive motor 222, thereby realizing the movement of the device. Multiple drive motors 222 are arranged in a circular array to ensure the stable operation of the device.

[0048] Compared with the prior art, the device of the present application realizes automated and efficient welding operations through the combination of the welding module and the movement module, solving the problems of low welding efficiency and complex operation in the inner wall welding of tee pipes in pipeline engineering. Traditional welding processes mainly rely on manual operation or semi-automatic equipment, which not only increases the labor intensity but also poses safety hazards. Especially inside narrow pipelines, it is difficult for manual operation to ensure the welding angle and the uniformity of the weld seam. However, the device of the present application realizes efficient and precise welding operations through automated design, greatly improving the welding efficiency and simplifying the operation process.

[0049] In summary, the present application realizes automated and efficient welding on the inner wall of the pipeline through the combination of the welding module and the movement module. The welding torch 12 in the welding module can rotate around the central axis and perform telescopic movement through the telescopic rod 13, thereby flexibly performing the welding operation. The rollers 21 and the drive assembly in the movement module cooperate with each other, enabling the device to move within the pipeline to the position where welding is required. The rollers 21 are arranged in a circular array along the central axis of the housing 11, making the movement of the device within the pipeline more stable and precise. The drive assembly drives the rollers 21 to rotate through the cooperation of the bidirectional gear ring 221 and the drive motor 222, thereby realizing the movement of the device. Multiple drive motors 222 are arranged in a circular array to ensure the stable operation of the device. Through the mutual cooperation of these technical features, the problems of low welding efficiency and complex operation in the inner wall welding of tee pipes in pipeline engineering are solved.

[0050] Furthermore, the present application also proposes that a rubber tire is sleeved outside the roller 21, and patterns are provided on the outside of the rubber tire.

[0051] A rubber tire is sleeved outside the roller 21, and patterns are provided on the outside of the rubber tire. By increasing the friction and adhesion, the stability of the roller 21 during movement in the pipeline is improved. These technical features cooperate with each other to solve the problems of the stability and adhesion of the roller 21 during movement in the pipeline.

[0052] The rubber tire can be made of wear-resistant rubber material to ensure that it is not easily worn during long-term use in the pipeline. The design of the patterns can be adjusted according to actual needs. For example, longitudinal or transverse stripes, grid-like patterns, wavy patterns, etc. can be adopted to further enhance the grip and friction of the roller 21. In addition, the size and shape of the rubber tire and the patterns can also be optimized according to the inner diameter of the pipeline and the size of the roller 21 to ensure the best adhesion effect.

[0053] By sleeving a rubber tire outside the roller 21 and providing patterns on the outside of the rubber tire, the present application can effectively improve the stability and adhesion of the roller 21 during movement in the pipeline, avoid slipping or deviation of the roller 21 during movement, and ensure the smooth operation of the device in the pipeline. Compared with the prior art, the present application solves the problems of the stability and adhesion of the roller 21 during movement in the pipeline through simple and effective technical means, and improves the working efficiency and reliability of the device.

[0054] Furthermore, the present application also proposes that a circular electric track 31 is provided on one side of the housing 11, and one end of the welding torch 12 is installed on a slider 32 that rotates in the electric track 31; a through hole 111 is provided in the middle of the housing 11, and an installation pipe 112 is sleeved inside the through hole 111. The installation pipe 112 is rotatably connected to the through hole 111 through a rotating bearing; a clamping wedge is provided inside the installation pipe 112; the cable 113 of the welding torch 12 passes through the installation pipe 112, and a clamp is sleeved outside it; a card slot is provided on the outside of the clamp; the clamping wedge cooperates with the card slot to fix the cable 113.

[0055] A circular electric track 31 is provided on one side of the housing 11, and one end of the welding torch 12 is installed on the slider 32 inside the electric track 31, so that the welding torch 12 can move along the track, improving the flexibility and precision of welding. The through hole 111 in the middle of the housing 11 is connected to the installation pipe 112 through a rotating bearing, ensuring that the installation pipe 112 can rotate stably and further enhancing the welding stability. The cable 113 of the welding torch 12 passes through the installation pipe 112 and is fixed by the clamp and the card slot, preventing the cable 113 from moving during the welding process and ensuring the continuity and stability of the welding process.

[0056] The setting of the electric track 31 enables the welding torch 12 to move flexibly along the track, thereby improving the flexibility and precision of welding. The mounting pipe 112 connected by the rotating bearing ensures the stable rotation of the mounting pipe 112, further improving the stability of welding. The wedge and slot structure for fixing the cable 113 avoids the movement of the cable 113 during the welding process, thus ensuring the continuity and stability of the welding process. The combined action of these technical features significantly improves the stability and welding precision of the welding torch 12 during the welding process of the inner wall of the pipe.

[0057] In this application, by setting the circular electric track 31 and the slider 32 structure, the welding torch 12 can move flexibly, improving the welding precision. Through the mounting pipe 112 connected by the rotating bearing, the stability of the welding torch 12 is ensured. The design of the wedge and slot effectively fixes the cable 113 of the welding torch 12, avoiding the movement of the cable 113 during the welding process and ensuring the continuity and stability of welding. Compared with the prior art, this application has significant advantages in improving the welding stability and precision.

[0058] Furthermore, this application also proposes that both the wedge and the slot are set to be triangular, and the apex angle is set to be an acute angle.

[0059] The triangular design of the wedge and slot and its acute apex angle can provide a better fitting effect, making the cable 113 more stable when fixed, reducing the risk of loosening and falling off. By adopting the triangular structure and the acute apex angle, the solution of this application can effectively solve the stability problem of the wedge and slot when fixing the cable 113, ensure the reliable fixation of the cable 113 of the welding torch 12, and thus improve the efficiency and quality of the welding operation.

[0060] Specifically, the triangular design of the wedge and slot can adopt the form of an isosceles triangle or a right triangle, and the acute angle of the apex angle can be selected between 30 degrees and 60 degrees. As a preferred implementation manner, the apex angle of the wedge and slot can be set to 45 degrees. Such a design can facilitate manufacturing and installation while ensuring stability. In addition, the wedge and slot can be made of different materials, such as metal, hard plastic, etc., to adapt to different usage environments and requirements.

[0061] By designing the wedge and slot to be triangular and setting the apex angle to be an acute angle, this application significantly improves the fixing stability of the cable 113. Compared with the prior art, the design of this application can better prevent the loosening and falling off of the cable 113, ensure the stability and reliability of the welding torch 12 during the welding process, and thus improve the welding quality and efficiency.

[0062] Furthermore, this application also proposes that both the wedge and the slot are provided with a plurality of them.

[0063] There are multiple clamping wedges and clamping grooves. By increasing the number of clamping wedges and clamping grooves, the fixing effect of the cable 113 can be improved, ensuring the stable operation of the welding torch 12 during the welding process, thereby enhancing the welding quality and efficiency.

[0064] The multiple settings of the clamping wedges and clamping grooves can be achieved by respectively arranging multiple clamping wedges and clamping grooves on the mounting pipe 112 and the clamp. Specifically, multiple clamping wedges can be evenly distributed on the inner side of the mounting pipe 112, and multiple clamping grooves are correspondingly formed on the outer part of the clamp. In this way, through the cooperation of multiple clamping wedges and clamping grooves, the cable 113 can be fixed more firmly, preventing the cable 113 from loosening or displacing during the welding process. In addition, the shapes of the clamping wedges and clamping grooves can be optimized according to actual needs, for example, set as triangles to increase the stability of the cooperation.

[0065] By increasing the number of clamping wedges and clamping grooves, the present application can effectively solve the problem of insufficient number of clamping wedges and clamping grooves, improve the fixing effect of the cable 113, ensure the stable operation of the welding torch 12 during the welding process, thereby enhancing the welding quality and efficiency. Compared with the prior art, the technical solution of the present application realizes higher welding stability and quality through simple and effective structural improvements, and has significant practical value.

[0066] Furthermore, the present application also proposes that a fixing ring 41 is coaxially sleeved outside the electric track 31; the fixing ring 41 is circular, and the width value thereof fluctuates periodically; the maximum width positions and the minimum width positions of the fixing ring 41 are alternately distributed, and the interval between two adjacent ones is 90 degrees; a groove is formed in the middle of the side of the slider 32 facing the fixing ring 41, and an induction component is slidably installed inside; the induction component includes a spring 421 arranged at the bottom of the groove, an electrode rod 422 placed between the spring 421 and the fixing ring 41, and electrode plates 423 arranged on both sides of the groove; the electrode plates 423 are electrically connected to a controller; the controller is electrically connected to the telescopic rod 13 and is used to control the automatic lifting of the telescopic rod 13.

[0067] The fixing ring 41 is coaxially sleeved outside the electric track 31. The fixing ring 41 is circular and the width value thereof fluctuates periodically. The maximum width positions and the minimum width positions are alternately distributed, and the interval between two adjacent ones is 90 degrees. This setting enables the slider 32 to be accurately positioned on the fixing ring 41. A groove is formed in the middle of the side of the slider 32 facing the fixing ring 41, and an induction component is slidably installed inside the groove. The induction component includes a spring 421 arranged at the bottom of the groove, an electrode rod 422 placed between the spring 421 and the fixing ring 41, and electrode plates 423 arranged on both sides of the groove. The electrode plates 423 are electrically connected to a controller, and the controller is electrically connected to the telescopic rod 13 and is used to control the automatic lifting of the telescopic rod 13. This setting enables the welding torch 12 to accurately move and be controlled on the electric track 31, solving the problem of the accuracy of the positioning and movement of the welding torch 12.

[0068] The spring 421 in the sensing component can be designed with different stiffnesses to adapt to different welding conditions. The electrode rod 422 can be designed with different lengths and diameters to ensure the contact stability with the fixed ring 41. The electrode plate 423 can be made of different materials to improve its conductivity and durability. The controller can be programmed to implement different automatic lifting strategies according to different welding requirements. The driving mode of the telescopic rod 13 can adopt various forms such as electric, pneumatic or hydraulic to adapt to different application environments.

[0069] Through the above technical solutions, the present application provides a device capable of precisely controlling the movement and positioning of the welding torch 12, solving the problem of maintaining a fixed distance between the welding torch 12 and the hole to be welded when moving on the electric track 31. Compared with the prior art, the present application can significantly improve the welding precision and efficiency, reduce manual intervention, lower the labor intensity, and improve the operation safety.

[0070] Furthermore, the present application also proposes that the contact end of the electrode rod 422 with the fixed ring 41 is set as a hemispherical structure, and the contact surface is coated with grease.

[0071] The contact end of the electrode rod 422 with the fixed ring 41 is set as a hemispherical structure, and the contact surface is coated with grease. The hemispherical structure design can reduce the friction of the contact surface, and coating the grease further reduces the frictional resistance, thereby ensuring the smooth operation of the contact surface between the electrode rod 422 and the fixed ring 41 during the welding process, avoiding jamming and wear, and improving the working efficiency and service life of the equipment.

[0072] The contact end of the electrode rod 422 with the fixed ring 41 can be made of various materials. For example, wear-resistant alloy materials or high-strength steel can be used to ensure good performance in a high-temperature and high-pressure welding environment. The selection of the grease can be adjusted according to the specific use environment. For example, high-temperature grease can be selected in a high-temperature environment to ensure the durability of the lubrication effect. In addition, the coating method of the grease can adopt various methods such as spraying, brushing or dipping to ensure the uniform coverage of the grease on the contact surface. As a preferred implementation mode, tiny grooves or textures can be set on the contact surface between the electrode rod 422 and the fixed ring 41 to further enhance the adhesion and lubrication effect of the grease.

[0073] The present application effectively solves the lubrication problem of the contact surface between the electrode rod 422 and the fixed ring 41 during the welding process by designing the contact end of the electrode rod 422 with the fixed ring 41 as a hemispherical structure and coating the contact surface with grease. Compared with the prior art, this design not only reduces the frictional resistance of the contact surface, avoids jamming and wear, but also improves the working efficiency and service life of the equipment. Thus, the present application provides a more efficient and reliable welding device, which can significantly improve the welding quality and the stability of the equipment in practical applications.

[0074] Furthermore, the present application also proposes a forming process for a tee pipe used in pipeline engineering. Using the forming equipment for the tee pipe used in pipeline engineering described in any of the above items, the process includes the following steps:

[0075] By using the forming equipment for the tee pipe used in pipeline engineering of the present application, the forming process of the present application realizes efficient and simple welding of the inner wall of the pipeline by means of steps such as a vertical feeding device, a cable 113 bundled with a clamp, a driving roller 21 for moving the device, a welding torch 12 moving along the hole edge, and the driving device returning to the entrance. This process ensures welding accuracy through a positioning method where the normal line of the equipment is parallel to the central axis of the pipeline hole; the cable 113 is fixed by bundling the cable 113 used by the welding torch 12 with a clamp and the cooperation of the slot and wedge on the clamp; the cooperation of the driving component and the roller 21 enables the equipment to accurately move to the welding position; the welding torch 12 moves along the hole edge driven by the slider 32 and the telescopic rod 13 to achieve automatic welding; finally, the driving component drives the roller 21 to make the equipment return to the entrance, completing the welding process.

[0076] Among them, in step S1, the equipment is vertically fed into the pipeline to be welded, and the normal line of the equipment is parallel to the central axis of the hole waiting to be welded on the pipeline. Such a positioning method ensures the welding accuracy. In step S2, the cable 113 used by the welding torch 12 is bundled with a clamp, and the slot on the clamp is matched with the wedge and inserted into the mounting pipe 112. This operation ensures the fixation of the cable 113 and avoids the influence of the shaking of the cable 113 during the welding process on the welding quality. In step S3, the driving component drives the roller 21 to rotate. Driven by the roller 21, the equipment moves to the position of the hole waiting to be welded on the pipeline until the plane projection of the hole coincides with the electric track 31. This step ensures that the equipment can be accurately positioned at the welding position. In step S4, the welding torch 12 is driven by the slider 32 and the telescopic rod 13 to move along the edge of the hole, completing the welding work on the inner wall of the pipeline between the two ends of the pipeline. This process realizes automatic welding and improves the welding efficiency. In step S5, the driving component drives the roller 21 to rotate. Driven by the roller 21, the driving device returns to the pipeline entrance, completing the entire welding process.

[0077] For example, in step S3, the driving component can drive the roller 21 through a motor to move the equipment along the inside of the pipeline until the electric track 31 of the equipment coincides with the plane projection of the hole. In step S4, the welding torch 12 can move on the electric track 31 through the slider 32, and at the same time, the telescopic rod 13 controls the telescopic movement of the welding torch 12 to ensure that the welding torch 12 moves evenly along the hole edge to complete the welding work. In step S5, the driving component drives the roller 21 again to make the equipment return to the pipeline entrance, facilitating the removal of the equipment and the next use.

[0078] The forming process of this application solves the problems of low welding efficiency and complex operation on the inner wall of the pipeline in the traditional process through the application of automated equipment. Compared with the prior art, the process of this application not only improves the welding efficiency, reduces the complexity of manual operation, but also improves the welding precision and uniformity, significantly enhancing the construction quality of pipeline projects.
