[0001] This utility model relates to the field of natural gas pipeline processing technology, and in particular to a natural gas pipeline bending processing equipment. Background Technology

[0002] Pipe bends are common pipe fittings, especially in natural gas transportation, where pipelines play a crucial role in the development and utilization of natural gas energy. Natural gas pipelines typically consist of long straight pipes and necessary bends to adapt to complex terrain and facility layouts. The manufacturing quality of bends directly affects the safety, stability, and operational efficiency of the entire pipeline system.

[0003] Natural gas pipelines are bent manually using bending tools (such as wrenches and pliers). The locations and angles for bending are marked on the natural gas pipeline to ensure that the bent pipeline meets the design requirements.

[0004] However, the existing manual bending of natural gas pipelines has low precision, which can easily lead to errors in parameters such as bending angle and radius, affecting the overall performance of the pipeline system. Summary of the Invention

[0005] The purpose of this utility model is to provide a natural gas pipeline bending processing equipment, which aims to solve the technical problem that the existing manual bending of natural gas pipelines has low precision, which easily leads to errors in parameters such as bending angle and radius, and affects the overall performance of the pipeline system.

[0006] To achieve the above objectives, this utility model employs a natural gas pipeline bending processing equipment, comprising a workbench, multiple support legs, a fixing component, and a bending component. The multiple support legs are all fixedly connected to the workbench and are all located below the workbench, while the fixing component is fixedly disposed above the workbench.

[0007] The bending assembly includes a U-shaped frame, a driving component, a transmission shaft, a traction rod, a movable rod, and a bending wheel. The U-shaped frame is fixedly connected to the workbench and located below the workbench. The transmission shaft is rotatably connected to the U-shaped frame and located inside the U-shaped frame. The driving component is disposed inside the U-shaped frame and connected to the transmission shaft. The workbench has a curved groove. One end of the traction rod is fixedly connected to the transmission shaft. The movable rod is fixedly connected to the other end of the traction rod and located inside the curved groove. The bending wheel is fixedly connected to the movable rod and sleeved on the outside of the movable rod.

[0008] The driving component includes a motor, a driving gear, and a driven gear. The motor is fixedly connected to the U-shaped frame and located inside the U-shaped frame. The driving gear is fixedly connected to the output end of the motor. The driven gear is fixedly connected to the transmission shaft and sleeved on the outside of the transmission shaft, and the driven gear meshes with the driving gear.

[0009] The bending assembly further includes a rubber washer, which is fixedly connected to the bending wheel and sleeved on the inner side wall of the bending wheel.

[0010] The fixing assembly includes a fixing base, two clamping plates, and two sets of pushing members. The fixing base is fixedly connected to the worktable and located above the fixing base.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please refer to Figures 1 to 4. This utility model provides a natural gas pipeline bending processing equipment, including a workbench 101, multiple support legs 102, a fixing component and a bending component. The multiple support legs 102 are all fixedly connected to the workbench 101 and are all located below the workbench 101. The fixing component is fixedly disposed above the workbench 101.

[0021] The bending assembly includes a U-shaped frame 103, a driving component, a transmission shaft 104, a traction rod 105, a movable rod 106, and a bending wheel 107. The U-shaped frame 103 is fixedly connected to the workbench 101 and is located below the workbench 101. The transmission shaft 104 is rotatably connected to the U-shaped frame 103 and is located inside the U-shaped frame 103. The driving component is disposed inside the U-shaped frame 103 and connected to the transmission shaft 104. The workbench 101 has a curved groove 108. One end of the traction rod 105 is fixedly connected to the transmission shaft 104. The movable rod 106 is fixedly connected to the other end of the traction rod 105 and is located inside the curved groove 108. The bending wheel 107 is fixedly connected to the movable rod 106 and is sleeved on the outside of the movable rod 106.

[0022] In this embodiment, when bending the pipeline, one end of the pipeline is first fixed to the fixing component, and the bending wheel 107 is located on the outside of the pipeline. Then, the driving component inside the U-shaped frame 103 is activated. The driving component drives the transmission shaft 104 to rotate in the U-shaped frame 103, and then the traction rod 105 is driven to rotate. The traction rod 105 drives the movable plate to move in the curved groove 108 of the workbench 101. At the same time, the bending wheel 107 is in close contact with the outer wall of the pipeline and bends along the trajectory of the curved groove 108. After bending is completed, the fixing of the pipeline is released, and then the bent pipeline can be taken out. Through the above method, the accuracy of bending natural gas pipelines can be greatly increased, errors in bending angle, radius and other parameters can be avoided, and the overall performance of the pipeline system can be guaranteed.

[0023] Furthermore, the driving component includes a motor 109, a driving gear 110, and a driven gear 111. The motor 109 is fixedly connected to the U-shaped frame 103 and located inside the U-shaped frame 103. The driving gear 110 is fixedly connected to the output end of the motor 109. The driven gear 111 is fixedly connected to the transmission shaft 104 and sleeved on the outside of the transmission shaft 104. The driven gear 111 meshes with the driving gear 110.

[0024] In this embodiment, the motor 109 is fixedly installed inside the U-shaped frame 103. When the traction rod 105 needs to be rotated, the motor 109 is started, and the output end of the motor 109 controls the rotation of the drive gear 110. Since the driven gear 111 meshes with the drive gear 110, the transmission shaft 104 is driven to rotate, and the transmission shaft 104 drives the traction rod 105 to rotate.

[0025] Furthermore, the bending assembly also includes a rubber washer 112, which is fixedly connected to the bending wheel 107 and sleeved on the inner sidewall of the bending wheel 107.

[0026] In this embodiment, by sleeved with the rubber washer 112 on the inner sidewall of the bending wheel 107, the rubber washer 112 can increase the friction between the bending wheel 107 and the pipe, making it easier to bend the pipe.

[0027] Further, the fixing assembly includes a fixing base 113, two clamping plates 114, and two sets of pushing members. The fixing base 113 is fixedly connected to the worktable 101 and is located above the fixing base 113. The two clamping plates 114 are symmetrically arranged inside the fixing base 113. Both sets of pushing members are fixedly connected to the fixing base 113 and are located on the outside of the fixing base 113. Each set of pushing members is fixedly connected to the corresponding clamping plate 114. The pushing member includes a support frame 116 and an electric telescopic rod 115. The support frame 116 is fixedly connected to the fixing base 113 and is located on the outer wall of the fixing base 113. The electric telescopic rod 115 is fixedly connected to the support frame 116 and is located inside the support frame 116. The output end of the electric telescopic rod 115 is fixedly connected to the clamping plate 114 and passes through the fixing base 113.

[0028] In this embodiment, when fixing the natural gas pipeline above the workbench 101, the natural gas pipeline is first inserted between the two clamping plates 114 in the fixing seat 113. Then, the electric telescopic rods 115 on the support frame 116 are activated respectively. The output end of each electric telescopic rod 115 drives the clamping plate 114 to move closer to the pipeline until the two clamping plates 114 clamp and fix the pipeline.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
