Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a butt joint device for chemical pipeline installation. Background Technique

[0002] An oil pipeline is composed of an oil pipe and its accessories, which are used to complete the tasks of oil unloading and transfer. The pipe material of the oil pipeline is generally steel pipe, and it is connected into a long-distance pipeline by using connecting devices such as welding and flange. At present, the oil pipeline has become one of the main transportation tools for oil. Pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor, and still has quite a development potential in the future. When connecting two pipelines, a butt joint device is needed.

[0003] When installing a pipeline, it is necessary to clamp and fix the pipeline with a fixed specification and carry out the butt joint work. When butt jointing, it is necessary to move the pipeline so that the pipe orifices of the two pipelines are in contact. When the pipeline moves, the friction between the pipeline and the butt joint device is relatively large, so it is not convenient to push the pipeline to move for butt joint. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the friction between the pipeline and the butt joint device in the prior art is relatively large, so it is not convenient to push the pipeline to move for butt joint, and a butt joint device for chemical pipeline installation is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a butt joint device for chemical pipeline installation, including a mobile vehicle. Both sides of the upper end of the mobile vehicle are fixedly connected with guide columns. A lifting mechanism is connected to the upper end of the mobile vehicle. Both sides of the lifting mechanism are fixedly connected with notch support blocks. Each guide column passes through the corresponding notch support block. Both sides of the upper end of the lifting mechanism are connected with mounting frames. Two parallel rotating shafts are rotatably connected to each mounting frame. Each notch support block is located between the two rotating shafts. A fixing mechanism for fixing the pipeline is connected to the lifting mechanism.

[0007] Preferably, an anti-collision pad is connected to the mobile vehicle.

[0008] Preferably, a push rod is fixedly connected to the upper end of the mobile vehicle.

[0009] Preferably, the lifting mechanism includes a movable frame. A first threaded hole is opened on the movable frame. The upper end of the mobile vehicle is rotatably connected with a first threaded rod. The first threaded rod is matched with the first threaded hole. The upper end of the first threaded rod is fixedly connected with a turntable. The movable frame is connected to the mounting frame, the notch support block and the fixing mechanism.

[0010] Preferably, the fixing mechanism includes a bottom plate which is slidably connected to the movable frame. A second threaded hole is formed in the bottom plate, and a second threaded rod is rotatably connected to the movable frame. The second threaded rod is engaged with the second threaded hole. Both sides of the upper end of the bottom plate are fixedly connected with support plates. Each support plate passes through the corresponding notch support block, and a pressing block is connected to the upper end of each support plate through a connecting plate. Each pressing block is engaged with the corresponding notch support block.

[0011] Preferably, an anti-slip pad is fixedly connected to the pressing block.

[0012] A docking device for chemical pipeline installation proposed by the present utility model has the beneficial effects that:

[0013] When docking pipelines, the pipelines are lifted, so that the bottom ends of the pipelines are separated from the notch support blocks, the bottom ends of the pipelines are in contact with the upper ends of the rotating shafts, and the rotating shafts support the pipelines. Then, when the pipelines are pushed, the rotating shafts rotate during the movement of the pipelines on the rotating shafts, and the pipelines are in rolling contact with the rotating shafts. The friction suffered by the pipelines during the movement is small, thus facilitating the movement of the pipelines and facilitating the docking of the two pipelines.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Embodiment 1: Refer to Figures 1-3 , a docking device for chemical pipeline installation, including a mobile vehicle 1, a collision cushion 2 is connected to the mobile vehicle 1, a push rod is fixedly connected to the upper end of the mobile vehicle 1, guide columns 3 are fixedly connected to both sides of the upper end of the mobile vehicle 1, a lifting mechanism 4 is connected to the upper end of the mobile vehicle 1, notch support blocks 7 are fixedly connected to both sides of the lifting mechanism 4, each guide column 3 passes through the corresponding notch support block 7, mounting brackets 5 are connected to both sides of the upper end of the lifting mechanism 4, two parallel rotating shafts 6 are rotatably connected to each mounting bracket 5, each notch support block 7 is located between the two rotating shafts 6, and the bottom end surface of the notch of the notch support block 7 and the upper end surface of the rotating shaft 6 are on the same straight line, and a fixing mechanism 8 for fixing the pipeline is connected to the lifting mechanism 4.

[0021] Working process:

[0022] Place the two pipelines on the two notch support blocks 7 respectively. The bottom end of the pipeline contacts the notch support block 7 and the upper end of the rotating shaft 6. When docking the pipelines, lift the pipelines so that the bottom end of the pipeline separates from the notch support block 7, and the bottom end of the pipeline contacts the upper end of the rotating shaft 6. The rotating shaft 6 supports the pipeline, and then push the pipeline. During the movement of the pipeline on the rotating shaft 6, the rotating shaft 6 rotates, and the pipeline and the rotating shaft 6 are in rolling contact. The friction suffered by the pipeline during the movement is small, so it is convenient to move the pipeline and facilitate the docking of the two pipelines;

[0023] Stop pushing the two pipelines when the pipe orifices of the two pipelines are in contact, and fix the two pipelines by squeezing them through the fixing mechanism 8, so that the pipe orifices of the two pipelines are in contact and docked.

[0024] Embodiment 2: In Embodiment 1, when docking two pipelines, the heights of the docking pipelines are different, so it is inconvenient to dock pipelines with different heights. Refer to Figure 2, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the lifting mechanism 4 includes a movable frame 41. A first threaded hole is formed in the movable frame 41. The upper end of the moving cart 1 is rotatably connected with a first threaded rod 42. The first threaded rod 42 is matched with the first threaded hole. The upper end of the first threaded rod 42 is fixedly connected with a turntable 43. The movable frame 41 is connected to the mounting frame 5, the notch support block 7 and the fixing mechanism 8. By rotating the turntable 43, the turntable 43 drives the first threaded rod 42 to rotate. After the first threaded rod 42 rotates, the movable frame 41 moves in the vertical direction. The movable frame 41 drives the notch support block 7 to move in the vertical direction, adjusting the height of the notch support block 7 to facilitate the support of pipes at different heights.

[0025] Embodiment 3: In Embodiment 1, when the two are butt-jointed and installed, it is necessary to respectively squeeze and fix the two pipes, and the pipe fixing speed is slow. Refer to Figure 4 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the fixing mechanism 8 includes a bottom plate 81. The bottom plate 81 is slidably connected to the movable frame 41. A second threaded hole is formed in the bottom plate 81. The movable frame 41 is rotatably connected with a second threaded rod 82. The second threaded rod 82 is matched with the second threaded hole. Both sides of the upper end of the bottom plate 81 are fixedly connected with support plates 83. Each support plate 83 passes through the corresponding notch support block 7. The upper end of each support plate 83 is connected with a pressing block 85 through a connecting plate 84. Each pressing block 85 is matched with the corresponding notch support block 7. An anti-slip pad is fixedly connected to the pressing block 85. When fixing the pipe, rotate the second threaded rod 82 to make the bottom plate 81 move downward. The bottom plate 81 drives the two support plates 83 to move. The two support plates 83 both drive the pressing blocks 85 to move through the connecting plates 84. The two pressing blocks 85 simultaneously squeeze and fix the two corresponding pipes, and the pipe fixing speed is fast.

[0026] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
