Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline connection, and specifically relates to a gas pipeline welding butt joint device. Background Art

[0002] The urban natural gas transmission and distribution system refers to a system consisting of all facilities from the gate station to the user, including the gate station or gas source plant compressor station, gas storage facilities, pressure regulating devices, transmission and distribution pipelines, metering devices, management facilities, monitoring systems, etc. In order to meet the large demand for gas, a large number of gas pipelines will be needed in the transportation process. During the connection process of the gas pipelines, the ends need to be welded. During welding, a welding docking device will be used to connect the two sections of gas pipelines to be welded together. However, in this process, the gas pipelines need to be lifted up when docking. When moving, the gas pipelines are usually long in size. Only the ends of the pipelines are lifted up, and the pipeline as a whole is in an inclined state. It is impossible to ensure that the pipe ends of the two sections of the pipeline are at the same level, which increases the difficulty of the welding process and easily causes problems such as uneven welds during welding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer toFigure 1-2 , the present utility model provides a technical solution: a gas pipeline welding docking device, including a top plate 1. Four corners of the bottom surface of the top plate 1 are fixedly assembled with support rods 2. Both sides of the bottom surface of the top plate 1 are fixedly assembled with ejector rods 3. A chute 4 is provided on the surface of the ejector rod 3. Two sliders 5 are slidably clamped on the inner wall of the chute 4. The bottom ends of the two sliders 5 are fixedly assembled with vertical rods 6. A connecting rod 7 is fixedly assembled between the two vertical rods 6 on the same side. Both sides of the bottom end of the ejector rod 3 are fixedly assembled with bases 8. One end of an electric push rod is fixedly assembled on the surface of the base 8, and the other end of the electric push rod is fixedly assembled with the connecting rod 7. A sleeve 10 is movably sleeved on the outer wall of the vertical rod 6. Two cylinders 11 are fixedly assembled on the side surface of the sleeve 10. The other ends of the two cylinders 11 are fixedly assembled with a top block 12. Lifting structures are installed at the bottom ends of the side surfaces of the two vertical rods 6 close to each other.

[0015] When welding and connecting the gas pipeline, place the top plate 1 above the two ends of the gas pipeline. At this time, the support rods 2 support the top plate 1. The positions of the top plate 1 and the two sections of gas pipeline are as Figure 2 shown in the figure. Start the lifting structure to lift the end of the gas pipeline. Start the lifting structure to lift the end of the gas pipeline, so that the position of the end is away from the placement plane. At this time, start the cylinder 11. After the cylinder 11 extends, it pushes the top block 12 against the pipeline to clamp the pipeline. After the clamping is completed, start the first electric push rod 9. The first electric push rod 9 starts to extend, pushing the connecting rod 7 to move. The connecting rod 7 drives the two vertical rods 6 on both sides to move together. At this time, the slider 5 moves on the inner wall of the chute 4. The two first electric push rods 9 on both sides extend simultaneously, driving the two sections of pipelines to move towards the middle position until the ends of the two pipelines fit together. At this time, start the lifting structure again to withdraw the two lifting structures from below the pipeline. At this time, under the action of gravity, the pipeline moves downward. At this time, the sleeve 10 moves downward along the outer wall of the vertical rod 6. The two sections of pipelines are in the same horizontal position. At this time, weld the connection position.

[0016] Specifically, the lifting structure includes a second electric push rod 13. The second electric push rod 13 is fixedly assembled on the vertical rod 6. The other end of the second electric push rod 13 is fixedly assembled with a support plate 14. The side surface of the support plate 14 is an inclined surface. A groove is provided on the bottom surface of the support plate 14. Two universal wheels are rotatably assembled on the inner wall of the groove. A rubber block 16 is fixedly assembled on the surface of the support plate 14.

[0017] The lifting structure can lift the end of the pipeline away from the placed plane, facilitating the movement of the pipeline. During use, the pipeline is placed between two pallets 14 on the same side. The inclined surfaces on the two pallets 14 are close to the pipeline. The second electric push rod 13 is activated, and the second electric push rod 13 starts to extend, pushing the pallet 14 to move. The universal wheels at the bottom of the pallet 14 roll along the placed plane. First, the pipeline contacts the inclined surface on the pallet 14, and the two pallets 14 on both sides move towards the middle simultaneously until the pipeline is placed on the rubber block 16 on the pallet 14. The rubber block 16 deforms due to its own elastic properties, preventing the pipeline from moving to both sides.

[0018] Specifically, a support 18 is fixedly assembled between the second electric push rod 13 and the vertical rod 6.

[0019] Fixing and installing the support 18 at the connection position between the second electric push rod 13 and the vertical rod 6 can reinforce the connection position and improve the stability of the second electric push rod 13.

[0020] Specifically, a gasket 17 is fixedly assembled at the bottom end of the support rod 2.

[0021] Fixing the gasket 17 at the bottom end of the support rod 2 improves the stability of the bottom end of the support rod 2.

[0022] Specifically, the top block 12 is made of rubber.

[0023] The top block 12 made of rubber can increase the contact friction force with the pipeline during use and enhance the clamping effect.

[0024] Working principle: Place the top plate 1 above the gas pipelines at both ends. Activate the lifting structure to lift the ends of the gas pipelines. Activate the lifting structure to lift the ends of the gas pipelines, making the positions of the ends away from the placed plane. At this time, activate the cylinder 11. After the cylinder 11 extends, it pushes the top block 12 against the pipeline to clamp the pipeline. After clamping, activate the first electric push rod 9. The first electric push rod 9 starts to extend, pushing the connecting rod 7 to move. The connecting rod 7 drives the two vertical rods 6 on both sides to move together. At this time, the slider 5 moves on the inner wall of the chute 4. The two first electric push rods 9 on both sides extend simultaneously, driving the two sections of the pipeline to move towards the middle position until the ends of the two pipelines are fitted together. At this time, activate the lifting structure again to withdraw the two lifting structures from below the pipeline. At this time, under the action of gravity, the pipeline moves downward. At this time, the sleeve 10 moves downward along the outer wall of the vertical rod 6. The two sections of the pipeline are at the same horizontal position. At this time, weld the connection position.
