Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically to a butt welding device for natural gas transmission pipelines. Background Technology

[0002] Natural gas pipelines refer to a network of pipelines and related facilities used for long-distance, large-scale transportation of commercial natural gas. Natural gas pipeline butt welding equipment refers to specialized machinery used to align and fix pipeline ends and weld circumferential seams. Its core mission is to ensure that a fully penetrated, mechanically superior circumferential weld is formed at the connection between two pipeline sections to meet the extreme requirements for the safe transportation of high-pressure, flammable natural gas.

[0003] Existing gas pipeline welding equipment uses two sets of semi-circular clamps to hold the ends of the two natural gas pipelines to be connected. This clamping ensures a tight fit between the two pipeline ends, and the rotating welding head between the two sets of clamps enables automatic welding. However, the support point of the welding equipment during operation is the contact point between the clamps and the natural gas pipeline. This means that the support of the welding equipment depends entirely on the clamping force between the clamps and the pipeline, resulting in poor support stability. Furthermore, the position adjustment of the welding equipment requires manual handling by the operator, which makes the angle and height adjustment of the welding equipment inconvenient, inefficient, and prone to affecting welding accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for connecting natural gas pipelines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a natural gas pipeline butt welding device, comprising a control seat, a base, a fixed track, a movable track, and a semi-circular clamp. The base is installed on one side of the outer wall of the control seat, and a fixed track is installed in the middle of the outer wall of the base. A movable track is rotatably connected to the bottom end of the outer wall of the fixed track, and the movable track and the fixed track can be fitted together to form a ring track. Semi-circular clamps are connected to both sides of the outer wall of the fixed track. A fixed seat is connected to the middle of the outer wall of the control seat, and a magnetic fixing component is connected to the top of the fixed seat. A support column is welded to the middle of the bottom end of the fixed seat, and an electromagnetic rotating column is rotatably connected to the middle of the outer wall of the support column. A support plate is welded to the bottom end of the electromagnetic rotating column. A rotating seat is fixedly connected to one side of the bottom end of the support plate, and an electromagnetic support seat is rotatably connected to the outer wall of the rotating seat. A protective box is fixedly connected to the bottom end of the outer wall of the electromagnetic support seat.

[0006] By allowing the welding equipment to rotate vertically and horizontally, operators can easily adjust the angle and orientation of the welding equipment, enabling it to be easily adjusted to the optimal welding posture.

[0007] Preferably, the fixed base and the magnetic fastener are magnetically connected, the rotating base and the electromagnetic support base are magnetically connected, and the outer wall of the electromagnetic rotating column is connected to a limiting member, which has a "U" shaped structure.

[0008] By inserting the control seat into the fixed seat and then moving the magnetic fastener to mate with the fixed seat, the fixed seat and the magnetic fastener are magnetically connected, thereby supporting and limiting the welding equipment, so that the support of the welding equipment no longer depends entirely on the clamping force of the clamp and the pipe.

[0009] Preferably, the support column has a limiting hole corresponding to the limiting member inside, and the limiting holes are distributed at equal angles. The bottom of the inner wall of the protective box is fixedly connected to a slide rail, and a slide seat is slidably connected to the outer wall of the slide rail.

[0010] The horizontal movement limiter disengages from the support column, thereby canceling the limit on the support column. Then, the fixed seat is rotated so that the support column rotates along the electromagnetic rotating column. At this time, the fixed seat will drive the welding equipment to rotate vertically.

[0011] Preferably, the slide block has a "U" shaped structure, and pins are slidably connected to both sides of the bottom end of the slide block. The slide rail has through holes corresponding to the pins, and the through holes are evenly distributed.

[0012] By moving the pin to disengage from the slide rail, the limit on the slide block is released, and then the slide block is pushed to move horizontally along the slide rail.

[0013] Preferably, a rotating rod is rotatably connected to the top of the slide block, and the top of the rotating rod is rotatably connected to the bottom of the support plate. A base is provided below the protective box, and fixed columns are welded to both sides of the top of the base.

[0014] The movement of the slide will cause the rotating rod to rotate. At this time, the angle between the rotating rod and the slide will change. The magnetic connection between the electromagnetic support and the rotating seat is canceled in advance, which will generate a thrust on the support plate, causing the rotating seat to rotate horizontally along the electromagnetic support.

[0015] Preferably, a lifting column is slidably connected inside the fixed column, and the top of the outer wall of the lifting column is fixedly connected to the bottom of the protective box. The lifting column has equally spaced fixing holes inside, and a limit seat is connected inside the fixing holes.

[0016] The operator can lift the protective box and move it upwards. At this time, the lifting column will slide along the fixed column, which will then guide the protective box to move upwards smoothly until the protective box drives the welding equipment to the designated height.

[0017] Preferably, a transmission rod is rotatably connected to the middle of the outer wall of the limiting seat, and a cover plate is rotatably connected to the bottom end of the transmission rod. The limiting seat has a "T" shaped structure, the transmission rod has an "eight" shaped structure, and lower pressure plates are fixedly connected to both sides of the outer wall of the cover plate.

[0018] The downward movement of the cover plate will cause the transmission rod to rotate. The rotation of the transmission rod will then exert a pulling force on the limit seat, causing the limit seat to disengage from the fixing hole inside the lifting column, thereby canceling the limit on the lifting column.

[0019] Preferably, the cover plate has slidably connected limit posts on both sides inside, and a spring is sleeved in the middle of the outer wall of the limit post. The bottom end of the outer wall of the limit post is fixedly connected to the base, and the lower pressure plate has an "L" shaped structure.

[0020] The cover plate is guided to move smoothly downward by the limiting post, and the downward movement of the cover plate will compress the spring, causing it to deform.

[0021] As can be seen from the above, the natural gas pipeline butt welding equipment provided by this utility model has the following beneficial effects.

[0022] 1. By supporting and limiting the welding equipment, the support of the welding equipment no longer depends entirely on the clamping force between the clamp and the pipeline, thereby improving the support stability of the welding equipment and preventing the welding equipment from being affected by the vibration of the construction site or pipeline.

[0023] 2. By allowing the welding equipment to rotate vertically and horizontally, operators can easily adjust the angle and orientation of the welding equipment, enabling it to be easily adjusted to the optimal welding posture, thereby improving operational efficiency.

[0024] 3. Simply press down the pressure plate with your foot to remove the limit on the lifting column, making it easier for operators to adjust the height of the welding equipment so that the height of the welding equipment corresponds to the height of the pipeline, thereby improving the flexibility of use.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-10This utility model provides a technical solution: a natural gas pipeline butt welding device, including a control seat 1, a base 2, a fixed track 3, a movable track 4, and a semi-circular clamp 5. The base 2 is installed on one side of the outer wall of the control seat 1, and the fixed track 3 is installed in the middle of the outer wall of the base 2. The movable track 4 is rotatably connected to the bottom of the outer wall of the fixed track 3, and the movable track 4 and the fixed track 3 can fit together to form a ring track. The semi-circular clamp 5 is connected to both sides of the outer wall of the fixed track 3. The fixed seat 6 is connected to the middle of the outer wall of the control seat 1, and the top of the fixed seat 6 is connected to a magnetic fixing member 7. The bottom middle of the fixed seat 6 is welded to a support column 8, and the middle of the outer wall of the support column 8 is rotatably connected to an electromagnetic rotating column 9. The bottom of the outer wall of the electromagnetic rotating column 9 is welded to a support plate 10, and a rotating seat 11 is fixedly connected to one side of the bottom of the support plate 10. The outer wall of the rotating seat 11 is rotatably connected to an electromagnetic support seat 12. A protective box 14 is fixedly connected to the bottom of the outer wall of the seat 12; the fixed seat 6 is magnetically connected to the magnetic fastener 7, the rotating seat 11 is magnetically connected to the electromagnetic support seat 12, and the outer wall of the electromagnetic rotating column 9 is connected to the limiting member 13, which has a "U" shaped structure; the support column 8 has a limiting hole corresponding to the limiting member 13, and the limiting holes are distributed at equal angles; the bottom of the inner wall of the protective box 14 is fixedly connected to the slide rail 15, and the outer wall of the slide rail 15 is slidably connected to the slide seat 16; the slide seat 16 has a "U" shaped structure, and the bottom two sides of the slide seat 16 are slidably connected to the pins 17; the slide rail 15 has through holes corresponding to the pins 17, and the through holes are distributed at equal intervals; the top of the slide seat 16 is rotatably connected to the rotating rod 18, and the top of the rotating rod 18 is rotatably connected to the bottom of the support plate 10; a base 19 is provided below the protective box 14, and fixed columns 20 are welded to the top two sides of the base 19.

[0029] For specific implementation, please refer to Figures 1-4 First, move the base 19 to the vicinity of the natural gas pipeline. Then, open the movable track 4 and the semi-circular clamp 5 on the outer wall of the base 2, so that the natural gas pipeline moves into the fixed track 3. Then close the movable track 4 and the semi-circular clamp 5. At this time, the fixed track 3 and the movable track 4 form a ring track. At the same time, the semi-circular clamp 5 clamps the ends of the two sets of natural gas pipelines that need to be connected. While clamping, it can make the two sets of pipeline openings fit tightly. Then, start the rotating welding head inside the fixed track 3 through the control seat 1. After that, the rotating welding head will move along the ring track, thereby automatically welding the natural gas pipeline (this is the prior art).

[0030] See Figures 5-7First, insert the middle part of the control seat 1 into the fixed seat 6. Then, move the magnetic fixing part 7 to dock with the fixed seat 6. At this time, the fixed seat 6 and the magnetic fixing part 7 are magnetically connected, thereby supporting and limiting the welding equipment. This makes the support of the welding equipment no longer completely dependent on the clamping force of the clamp and the pipe, thereby improving the support stability of the welding equipment and preventing the welding equipment from being affected by the vibration of the construction site or the pipe.

[0031] First, the horizontally moving limiting member 13 disengages from the support column 8, thereby canceling the limiting of the support column 8. Then, the fixed base 6 is rotated to make the support column 8 rotate along the electromagnetic rotating column 9. At this time, the fixed base 6 will drive the welding equipment to rotate vertically. After that, the moving limiting member 13 passes through the support column 8 and the electromagnetic rotating column 9, and at the same time, the electromagnetic rotating column 9 is activated to form a magnetic attraction connection with the support column 8, thereby limiting and fixing the welding equipment to prevent it from continuing to rotate.

[0032] Next, the movable pin 17 is disengaged from the slide rail 15, thereby canceling the limit on the slide block 16. Then, the slide block 16 is pushed to move horizontally along the slide rail 15. Since the slide block 16 and the rotating rod 18 are rotatably connected, the movement of the slide block 16 will drive the rotating rod 18 to rotate. At this time, the angle between the rotating rod 18 and the slide block 16 will change. The magnetic connection between the electromagnetic support seat 12 and the rotating seat 11 is canceled in advance, thereby generating a pushing force on the support plate 10, causing the rotating seat 11 to rotate horizontally along the electromagnetic support seat 12 until the support plate 10 rotates to the designated position. At this time, the electromagnetic support seat 12 and the rotating seat 11 are magnetically connected. Then, the movable pin 17 is inserted into the slide rail 15, thereby limiting and fixing the support plate 10 to prevent the support plate 10 from rotating arbitrarily in the horizontal direction. This makes it easier for operators to adjust the angle and orientation of the welding equipment, allowing the equipment to be easily adjusted to the optimal welding posture, thereby improving operational efficiency.

[0033] See Figure 2 , Figure 8 , Figure 9 and Figure 10 A lifting column 21 is slidably connected inside the fixed column 20, and the top of the outer wall of the lifting column 21 is fixedly connected to the bottom of the protective box 14. The lifting column 21 has equally spaced fixing holes 22, and the fixing holes 22 are connected to the limiting seat 23. A transmission rod 24 is rotatably connected to the middle of the outer wall of the limiting seat 23, and a cover plate 25 is rotatably connected to the bottom of the transmission rod 24. The limiting seat 23 has a "T" shaped structure, and the transmission rod 24 has an "eight" shaped structure. The lower pressure plate 26 is fixedly connected to both sides of the outer wall of the cover plate 25. A limiting column 27 is slidably connected to both sides inside the cover plate 25, and a spring 28 is sleeved in the middle of the outer wall of the limiting column 27. The bottom of the outer wall of the limiting column 27 is fixedly connected to the base 19. The lower pressure plate 26 has an "L" shaped structure.

[0034] In practice, first press down the pressure plate 26 with your foot, so that the pressure plate 26 drives the cover plate 25 to move downward along the limiting post 27. At this time, the limiting post 27 guides the cover plate 25 to move downward smoothly. Then, the downward movement of the cover plate 25 will drive the transmission rod 24 to rotate. At the same time, the downward movement of the cover plate 25 will squeeze the spring 28, causing it to deform. After that, the rotation of the transmission rod 24 will generate a pulling force on the limiting seat 23, so that the limiting seat 23 is disengaged from the fixing hole 22 inside the lifting column 21, thereby canceling the limitation on the lifting column 21. Then, the operator can lift the protective box 14 to move it upward. At this time, the lifting column 21 will slide along the fixing post 20, thereby guiding the protective box 14 to move upward smoothly until the protective box 14 drives the welding equipment to move up to the designated height. Next, the spring force generated by the reset of the spring 28 drives the cover plate 25 to move upward. At this time, the limit seat 23 will move away from each other until the limit seat 23 is inserted into the corresponding fixing hole 22, thereby limiting the lifting column 21 to prevent it from moving downward. Thus, the limit on the lifting column 21 can be canceled by simply pressing the pressure plate 26 with your foot, which makes it convenient for the operator to adjust the height of the welding equipment so that the height of the welding equipment corresponds to the height of the pipeline, thereby improving the flexibility of use.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
