Description

Technical Field

[0001] This invention relates to the field of steam insulation pipe welding equipment technology, specifically to a steam insulation pipe internal and external welding device. Background Technology

[0002] Steam-insulated pipes are short for thermally insulated pipes. They are used for transporting liquids, gases, and other media in industries such as petroleum, chemical, aerospace, hot springs, military, district heating, central air conditioning, and municipal pipelines. Steam-insulated pipes are suitable for transporting various media within a temperature range of -50°C to 150°C. They are widely used in district heating, cooling, and hot oil transportation, as well as in insulation and cold storage projects in industries such as greenhouses, cold storage facilities, coal mines, petroleum, and chemicals. In the laying of steam-insulated pipes, they are often constructed by welding prefabricated sections of insulated pipe together, forming a joint structure at the weld joint. This joint structure is widely used in the field of steam-insulated pipe laying. Publication number "CN216706547U" discloses a steam insulation pipe jointing structure, which facilitates the alignment of two insulation pipes during welding and increases the stability of the weld joint, making it less prone to breakage. The structure includes two insulation pipes, each with an adjusting box below it. The two adjusting boxes are fixedly connected by multiple connecting rods. A bidirectional screw is rotatably connected to each adjusting box, and two sliders are threaded onto the bidirectional screw. Each slider has a clamping block installed on it, and both clamping blocks are in contact with the insulation pipe. A transmission sleeve is provided on the bidirectional screw, and a conveyor belt is fitted onto the two transmission sleeves. A connecting plate is rotatably connected to one of the adjusting boxes, and the connecting plate is fixedly connected to the bidirectional screw on the same side. An electromagnetic chuck is installed on this adjusting box, and two magnetic blocks and a rocker arm are installed on the connecting plate.

[0003] However, the existing technology and the above-mentioned technology still have the following drawbacks: 1. During the welding process, the temperature of the welding area rises rapidly, which can cause deformation of the weld joint and its surroundings, and may also cause the weld between the inner and outer tubes to burst. 2. Traditional joint welding devices can only weld the external joints of pipes. However, they cannot compensate for situations where the weld between the inner and outer pipes may burst due to thermal expansion and contraction during the welding process. This requires manual secondary welding, which reduces welding efficiency. 3. The lack of a collection device for welding slag after it falls off results in a large amount of residue on the welding table. After welding is completed, manual cleaning is required, and the slag splash may also affect the normal operation of other electrical equipment. Summary of the Invention

[0004] This invention provides a welding device for the inner and outer surfaces of steam insulation pipes, solving the problems mentioned in the background art. During welding, the temperature at the welding site rises rapidly, causing deformation of the weld joint and its surrounding area, and potentially leading to weld cracking of the inner and outer pipes. Traditional welding repair devices can only weld the external interfaces of pipes, but they cannot compensate for weld cracking of the inner and outer pipes due to thermal expansion and contraction during welding, requiring manual secondary welding and reducing welding efficiency. Furthermore, the lack of a collection device for weld slag results in a large amount of residue on the welding table, requiring manual cleaning after welding, and slag spatter may also affect the normal operation of other electrical equipment.

[0015] The present invention has the following beneficial effects: 1. The steam insulation pipe internal and external welding device is equipped with a spray component to cool the high temperature weld joint generated during the welding process in time, so as to avoid deformation and cracking of the weld joint due to excessive temperature. At the same time, it can also reduce the temperature of the welding area and improve the working environment. 2. This steam insulation pipe internal and external welding device, by setting up a first welding section and a second welding section, realizes simultaneous welding or step-by-step welding of the inner and outer pipe interfaces of the steam insulation pipe. The first welding section can perform precise welding on the external pipe interface, while the second welding section can penetrate deep into the pipe to effectively weld and repair the inner pipe interface that may crack due to thermal expansion and contraction. No secondary manual operation is required, significantly improving welding efficiency and ensuring the overall welding quality of the pipeline.

[0016] 3. This steam insulation pipe internal and external welding device, by setting up a collection box, can effectively collect the welding slag generated during the welding process, preventing the welding slag from falling onto the welding table and forming a large amount of residue, thus reducing the amount of manual cleaning work. At the same time, the filter plate that can be detachably installed inside the collection box can initially separate the coolant and welding slag, facilitating the subsequent centralized treatment of welding slag and the recycling of coolant, and effectively preventing the impact of welding slag splashing on the normal operation of surrounding electrical equipment.

[0017] 4. This steam insulation pipe internal and external welding device, by setting an elastic drive device, when the second support plate drives the rolling wheel to roll on the inclined surface of the water bag, the water bag is squeezed. At this time, the corrugated plate is deformed under the action of the top rod, and the spring is compressed. When the rolling wheel leaves the water bag, the water bag rebounds and resets. The elastic force of the spring drives the collection box to reset. During this process, the collection box generates a slight vibration, which helps to prevent welding slag from accumulating and clogging in the collection box, and improves the smoothness of welding slag collection.

[0018] 5. This steam insulation pipe internal and external welding device, by setting a lifting assembly between the clamping plate and the first support plate, utilizes a motor to drive the first gear to rotate, which in turn drives the second gear and the internal threaded sleeve to rotate, causing the screw to lift and lower the clamping plate. This allows for flexible adjustment of the clamping wheel height according to the diameter of different specifications of steam insulation pipes, ensuring stable clamping of the pipe and enhancing the versatility of the device. Simultaneously, the synchronous pulley ensures that the two sets of screws lift and lower synchronously, further improving the stability of clamping.

[0019] 6. This steam insulation pipe internal and external welding device, by installing support rollers at the bottom of the second support plate, makes the second support plate move more smoothly on the second electric slide, reducing swaying during movement and ensuring the welding accuracy of the second welding part. The support rollers are in close contact with the surface of the welding table, providing good support for the second support plate, distributing the pressure of the second support plate on the second electric slide, and extending the service life of the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1 to 8This invention discloses a welding device for the inner and outer surfaces of a steam insulation pipe, including a welding table 1, a first welding part 4 on one side of the welding table 1, a first electric slide 2 symmetrically arranged on the welding table 1, a first support plate 9 arranged on the first electric slide 2, a clamping part arranged on the first support plate 9, a vertical plate 30 installed on the welding table 1 at a position corresponding to the first welding part 4, a rotating shaft 25 rotatably connected inside the vertical plate 30, and a six-jaw chuck 31 connected to one end of the rotating shaft 25.

[0031] In this embodiment, to achieve specific functions and operating procedures, a first welding section 4 is specially provided on one side of the welding table 1. This first welding section 4 can play a role in welding the connection structure between the inner and outer tubes in subsequent welding operations, undertaking the corresponding welding tasks. On the opposite side of the welding table 1, a vertical plate 30 is provided, which is equipped with a six-jaw chuck 31. The six-jaw chuck 31 can provide a stable clamping effect for the workpieces that need to be processed or welded, so as to ensure the stability of subsequent operations. At the same time, two sets of clamping parts are also specially provided. These two sets of clamping parts also play a key role in the entire operation process, and can effectively clamp the relevant components from different angles and positions.

[0032] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 It also includes a movable second support plate 20 between two sets of clamping parts, and a second welding part 18 is provided on the second support plate 20; the clamping part includes two sets of clamping plates 15, an electric cylinder 7 is provided on the clamping plate 15, a bracket 8 is connected to the output shaft end of the electric cylinder 7, a clamping ring 5 is connected to one side of the bracket 8, and clamping wheels 6 are arranged in a ring at equal intervals inside the clamping ring 5.

[0033] In this embodiment, the clamping part mainly consists of two sets of clamping plates 15, each of which is equipped with an electric cylinder 7 that provides power. When the electric cylinder 7 is activated, its output shaft drives the connected bracket 8 to extend and retract, thereby allowing the clamping ring 5 fixed to one side of the bracket 8 to move closer to or further away from the steam insulation pipe to be clamped. Inside the clamping ring 5, multiple clamping wheels 6 are arranged in a ring-shaped, equidistant array. When these clamping wheels 6 contact the insulation pipe, they not only stably clamp the insulation pipe using the force applied by the electric cylinder 7, preventing displacement during welding, but also allow the clamping wheels 6 to roll when the insulation pipe needs to rotate for circumferential welding, thus reducing resistance to the rotation of the insulation pipe and ensuring smooth welding. This design allows the clamping part to provide reliable clamping force while also meeting the rotation requirements of the insulation pipe during welding.

[0034] A lifting assembly is provided between the clamping plate 15 and the first support plate 9. The lifting assembly includes a screw 14 rotatably connected to the lower part of the clamping plate 15. An internal threaded sleeve 13 is rotatably installed inside the first support plate 9. The internal threaded sleeve 13 and the screw 14 are threadedly connected. A second gear 12 is connected to the bottom end of the internal threaded sleeve 13. A first gear 11 is meshed on one side of the second gear 12. A mounting plate 27 is connected to one side of the first support plate 9. A motor 10 is installed on one side of the mounting plate 27. The first gear 11 is fixedly installed on the output shaft end of the motor 10. A synchronous pulley 16 is connected to the upper end of the internal threaded sleeve 13. The two sets of synchronous pulleys 16 are connected in a transmission connection.

[0035] Specifically, this embodiment includes a lifting assembly that can flexibly adjust the height of the clamping part to adapt to the welding requirements of steam insulation pipes of different diameters. When the motor 10 starts, its output shaft drives the first gear 11 to rotate. The first gear 11 meshes with the second gear 12, thereby driving the internal threaded sleeve 13 to rotate within the first support plate 9. Since the internal threaded sleeve 13 is threadedly connected to the screw 14, and the top end of the screw 14 is rotatably connected to the clamping plate 15, the rotation of the internal threaded sleeve 13 is converted into the vertical linear motion of the screw 14, thereby driving the clamping plate 15 and the clamping ring 5 and other components mounted on it to rise and fall synchronously. At the same time, the synchronous pulley 16 connected to the upper end of the internal threaded sleeve 13 realizes the synchronous rotation of the two sets of internal threaded sleeves 13 through the synchronous belt, ensuring that the lifting height of the screws 14 on both sides is consistent, ensuring that the clamping plate 15 remains horizontal during the lifting process, and avoiding unstable clamping of the insulation pipe or displacement of the welding position due to the height difference on both sides.

[0036] A guide rod 17 is connected to the bottom of the clamping plate 15. The guide rod 17 passes through the first support plate 9 and is slidably connected to the first support plate 9.

[0037] Specifically, when the clamping plate 15 moves up and down, the guide rod 17 can slide along the preset holes on the first support plate 9, providing precise guidance for the up and down movement of the clamping plate 15. This effectively prevents the clamping plate 15 from unnecessary rotation or offset due to the rotation of the screw 14, ensuring the stability and accuracy of the movement trajectory of the clamping plate 15 during the lifting process, and further guaranteeing the precision of clamping the steam insulation pipe.

[0038] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 A second electric slide 3 is provided on one side of the welding table 1. A second support plate 20 is provided on the second electric slide 3. A second welding part 18 is provided on the second support plate 20. A support roller 24 is provided at the bottom of the second support plate 20. The bottom of the support roller 24 is fitted to the upper surface of the welding table 1. A rolling roller 26 is rotatably connected to the bottom surface of the second support plate 20.

[0039] In this embodiment, the second electric slide 3 installed on the welding table 1 provides power and guidance for the movement of the second support plate 20. When the second electric slide 3 is activated, its slider drives the second support plate 20 to move smoothly along the length of the welding table 1, allowing the second welding part 18 installed on the second support plate 20 to adjust its position according to welding requirements, thus enabling welding operations on different parts of the steam insulation pipe. The support roller 24 installed at the bottom of the second support plate 20 is in close contact with the upper surface of the welding table 1. During the movement of the second support plate 20, the support roller 24 rolls accordingly, which not only provides effective support for the second support plate 20 and distributes the pressure of the second support plate 20 and its components on the slider of the second electric slide 3, but also greatly reduces the friction force during the movement of the second support plate 20, ensuring smooth and stable movement and avoiding problems such as movement jamming or positional accuracy deviation caused by excessive friction.

[0040] Example 4 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 It also includes a spray assembly installed on the welding table 1. The spray assembly includes a spray pipe 34 that can spray coolant onto the welding joint. The spray assembly includes a water bladder 19, with a support plate 36 connected to the bottom of the water bladder 19. The support plate 36 is fixedly connected to the upper surface of the welding table 1. The water bladder 19 is a soft rubber bladder that can rebound and reset. The top of the water bladder 19 is provided with an inclined surface, and the rolling wheel 26 is fitted to the inclined surface. A connecting pipe 23 is connected to one side of the water bladder 19, and the connecting pipe 23 is connected to an external coolant storage tank. A water pipe 21 is connected to the top of the water bladder 19. The end of the water pipe 21 away from the water bladder 19 is fixed to the upper surface of the second support plate 20. A flexible hose 22 is connected between the water pipe 21 and the water bladder 19. A connecting pipe 32 is connected between adjacent water pipes 21. The connecting pipe 32 is connected to a connecting pipe 33 through a universal joint 35. The spray pipe 34 is connected to the connecting pipe 33 through the universal joint 35.

[0041] In this embodiment, the spray assembly is designed to cool the high-temperature weld joint generated during the welding process in a timely manner, so as to avoid problems such as deformation and cracking of the weld joint due to excessive temperature. It also reduces the temperature of the welding area and improves the working environment. When the second support plate 20 moves under the drive of the second electric slide 3, its bottom roller 26 continuously contacts and rolls against the inclined surface of the top of the water bladder 19. Since the water bladder 19 is a spring-loaded soft rubber bladder, the rolling of the roller 26 exerts a squeezing effect on the water bladder 19. When the water bladder 19 is squeezed, the coolant stored inside is forced out and enters the water pipe 21 through the hose 22. After the coolant collects in the water pipe 21, it is sprayed out from the spray pipe 34 through the connecting pipe 32 and the connecting pipe 33, precisely spraying the weld joint. When the roller 26 leaves the squeezed area, the water bladder 19 rebounds and resets itself. At this time, the coolant in the external coolant tank is replenished into the water bladder 19 through the connecting pipe 23, preparing for the next spray. The universal joint 35 allows for flexible multi-angle adjustment of the connecting pipe 33 and the spray pipe 34, enabling the spray pipe 34 to be precisely aligned with the spray area according to the specific location and angle of the weld joint, thus maximizing the cooling effect. The presence of the flexible hose 22 accommodates the relative positional changes between the water pipe 21 and the water bladder 19 when the second support plate 20 moves, preventing the pipes from being pulled or damaged.

[0042] Example 5 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 A collection box 28 is provided on the welding table 1 between the two sets of clamping parts, and the collection box 28 is located below the spray pipe 34. The bottom of the collection box 28 has a notch at the location where the first electric slide table 2 is set, and a filter plate 29 is detachably installed inside the collection box 28.

[0043] In this embodiment, the collection box 28 is positioned between the two sets of clamping parts and directly below the spray pipe 34. Its main function is to collect the coolant flowing down after the spray cooling during welding, as well as welding slag and other waste generated during welding. When the spray pipe 34 sprays coolant onto the welding port, the coolant absorbs heat and drips down along with some welding slag. This liquid-solid mixture can fall directly into the collection box 28 below, preventing the coolant from flowing around and contaminating the surface of the welding table 1 and the working environment. The bottom of the collection box 28 has a notch at the position corresponding to the placement of the first electric slide 2. This design is to avoid the structure of the first electric slide 2, ensuring that the collection box 28 can be placed smoothly on the welding table 1 without interfering with the first electric slide 2. At the same time, a filter plate 29 is detachably installed inside the collection box 28. The filter plate 29 can filter out solid impurities such as welding slag from the dripping mixture, separating the coolant from the impurities. In this way, the filtered coolant can be temporarily stored at the bottom of the collection box 28 for easy recycling or reuse. Meanwhile, the welding slag and other impurities trapped on the filter plate 29 can be cleaned by disassembling the filter plate 29 after accumulating to a certain extent. This not only ensures convenient collection but also helps to save resources and protect the environment.

[0044] Example 6 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 An elastic drive device is provided between the collection box 28 and the water bladder 19. The elastic drive device includes a top rod 38 connected to one side of the outer wall of the collection box 28, a corrugated plate 37 connected to the side of the support plate 36 near the collection box 28, the top rod 38 and the corrugated plate 37 are fitted together, a guide shaft 39 is connected to one side of the outer wall of the collection box 28, the guide shaft 39 and the support plate 36 are slidably connected, and a spring 40 is sleeved on the outside of the guide shaft 39. The spring 40 is connected between the support plate 36 and the collection box 28.

[0045] In this embodiment, the elastic drive device is mainly designed to separate the welding slag and coolant in a timely manner during the collection process of the collection box 28, while preventing the filter plate 29 from becoming clogged. The collection box 28 and the second support plate 20 move synchronously. When the second support plate 20 moves under the drive of the second electric slide 3, it indirectly drives the collection box 28 to move synchronously through related structures. During the movement of the collection box 28, the push rod 38 on one side of its outer wall will continuously contact the corrugated plate 37 on the support plate 36. Since the surface of the corrugated plate 37 is wavy, the push rod 38 will slide along the crests and troughs of the corrugated plate 37 as it moves with the collection box 28. When the push rod 38 slides past the crest, it will generate a thrust on the collection box 28 in a direction away from the support plate 36; and when the push rod 38 slides into the trough, under the tension of the spring 40 sleeved outside the guide shaft 39, the collection box 28 will reset towards the support plate 36. In this way, the collection box 28 will generate small reciprocating vibrations in the horizontal direction. This vibration effectively loosens solid impurities such as welding slag on the filter plate 29 inside the collection box 28, preventing them from accumulating tightly and clogging the filter pores of the filter plate 29. This ensures that the coolant can pass smoothly through the filter plate 29 for filtration, improving filtration efficiency and effect, while also reducing the frequency of manual cleaning of the filter plate 29. The guide shaft 39 provides stable guidance for the collection box 28 during vibration, preventing the collection box 28 from shifting or shaking during vibration, ensuring the stability and reliability of the vibration.
