Description

Technical Field

[0001] This application relates to the field of nuclear power plant mechanical equipment technology, and more specifically, to a welding machine pipeline integration device. Background Technology

[0002] In the construction and maintenance of nuclear power plants, welding is often required, and among various welding methods, plasma arc welding is one of the most widely used. Plasma arc welding is a welding method that uses a high-energy-density plasma arc beam as the welding heat source. In the plasma arc welding apparatus, a nozzle is installed inside the welding head, and a tungsten electrode is mounted on this nozzle. Cooling water flows through the inner wall of the nozzle, and argon gas is introduced into the top of the nozzle. Under the action of the cooling water, the electric arc at the nozzle is compressed to form an ionic arc, which serves as the heat source to melt the workpiece. The stable output of the plasma arc is a key factor affecting the welding effect. The most important measures to maintain plasma stability are the supply of plasma gas and cooling water. Therefore, plasma welding requires the comprehensive use of the electric arc, cooling water, shielding gas, and plasma gas to ensure welding quality.

[0003] In related technologies, plasma arc welding machines primarily focus on the mechanical and electrical structural design, often neglecting the proper arrangement of circuits, water systems, and gas systems. This neglect of their orderly integration prevents the effective utilization of factors significantly impacting welding quality, such as cooling water and the plasma arc, resulting in low weld quality. Furthermore, the complex distribution of various pipelines leads to a high failure rate in plasma arc welding machines, causing inconvenience during operation and subsequent maintenance, thus resulting in low work efficiency.

[0030] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0031] Figure 1 and Figure 2The diagram illustrates a welding machine piping integration device 1 in some embodiments of the present invention. This device 1 can be installed on a plasma arc welding machine 2 and integrates the piping used by the plasma arc welding machine 2, such as electrical circuits, water circuits, and gas circuits, thereby facilitating the user's operation of the plasma arc welding machine 2. Simultaneously, because the welding machine piping integration device 1 can integrate various piping systems of the plasma arc welding machine 2, the piping is centrally located, simplifying the wiring distribution and improving the convenience of wiring, thereby reducing the failure rate of the plasma arc welding machine 2. The welding machine piping integration device 1 also facilitates the production and maintenance of the plasma arc welding machine 2, simplifying the wiring procedures for maintenance personnel and improving maintenance efficiency. Furthermore, compared to fixing piping using methods such as strapping, the installation or connection method of the welding machine piping integration device 1 is simpler and more stable, thus providing better reliability.

[0032] See also Figure 2 In some embodiments, the welding machine piping integration device 1 may include a piping integration plate 10, a protective plate assembly 20 mounted on the piping integration plate 10, and a connecting plate 30 mounted at another location on the piping integration plate 10. The piping integration plate 10 has multiple mounting holes for installing various pipes required by the plasma arc welding machine 2. It can integrate the various pipes required by the plasma arc welding machine 2 onto the welding machine piping integration device 1, so that the pipes of the plasma arc welding machine 2 can be centrally arranged to facilitate the use and maintenance of the plasma arc welding machine 2.

[0033] Compared to the pipe integration plate 10, the protective plate assembly 20 has a larger dimension in the direction of pipe arrangement on the pipe integration plate 10, that is, the protective plate assembly 20 has a larger dimension in the thickness direction of the pipe integration plate 10. It can be used to protect the various pipe connections installed on the pipe integration plate 10, preventing accidental contact or collision at these connections, thereby maintaining the safe operating state of the plasma arc welding machine 2. Specifically, the size of the protective plate assembly 20 is larger than the size of the pipe connection portion installed on the pipe integration plate 10, thus protecting the pipes installed on the plasma arc welding machine 2. When the pipe integration plate 10 is displaced or vibrated, it can prevent external interference at the connection points between the pipes and the pipe integration plate 10, preventing situations such as pipe disconnection and ensuring a secure connection. The protective plate assembly 20 can also prevent accidental contact by the user, avoiding potential safety accidents such as electric shock during use.

[0034] The connecting plate 30 is installed at the end of the pipeline integration plate 10 and simultaneously on the plasma arc welding machine 2. It can be used to connect the pipeline integration plate 10 and the plasma arc welding machine 2 together, thereby realizing the connection between the welding machine pipeline integration device 1 and the plasma arc welding machine 2.

[0035] See also Figure 3 In some embodiments, the pipe integration plate 10 may include a pipe integration plate body 100, a first through hole 101, a fixing hole 102 located around the first through hole 101, a connector 103, and a pipe joint 104. In some embodiments, the pipe integration plate body 100 may be made of insulating material to prevent electric shock during operation and to facilitate the use of the plasma arc welding machine 2 under different working conditions, such as in a humid environment or in rainy weather.

[0036] The first through hole 101 is formed on the pipe integration plate body 100 and penetrates the opposite surface of the integration plate body 100. It can be used to connect pipes. In some embodiments, there are six first through holes 101 to meet the usage requirements of the plasma arc welding machine 2. Specifically, it can be used to install various power cords, plasma gas pipelines, etc. The first through holes 101 are spaced apart to prevent the pipelines from interfering with each other and to facilitate the user's management of the pipelines. The first through hole 101 can be a straight hole. In some embodiments, the first through hole 101 can also be a threaded hole, so that the pipeline installed on it can be fixed by threads. This fixing method has good airtightness, liquid tightness, and high connection firmness.

[0037] The fixing hole 102 is provided on the pipe integration plate body 100. It may penetrate the opposite surface of the pipe integration plate body 100 or not, depending on the thickness of the pipe integration plate body 100. In some embodiments, the fixing hole 102 may be a countersunk hole, which can be used to fix the pipe installed in the first through hole 101. There are at least 6 such holes, corresponding to 6 first through holes 101.

[0038] Understandably, the number of fixing holes 102 can also be 12 or other numbers, as long as they are sufficient to fix the pipes installed on the first through hole 101. In some embodiments, the number of fixing holes 102 is 12, arranged in 6 groups around the first through hole 101. Specifically, two fixing holes 102 are arranged around each first through hole 101, with the two fixing holes 102 positioned opposite each other on both sides of the first through hole 101. In some embodiments, they may be located in the diametrical direction of the first through hole 101. This allows for better fixation of the pipes installed on the first through hole 101. Understandably, three or four fixing holes around each first through hole 101 are also applicable, both of which can achieve the desired effect of effectively fixing the pipes installed on the first through hole 101.

[0039] The pipe connector 104 can be installed on the pipe integration plate 10 in various forms. Specifically, since the first through hole 101 can be set as a threaded hole or a straight hole, and fixing holes 102 are provided on both opposite sides of the first through hole 101, the pipe connector 104 can be directly threaded onto the pipe integration plate 10 through the threaded through hole 101. Alternatively, the pipe connector 104 can be first installed in the first through hole 101 and locked through the fixing holes 102. In this case, the pipe connector 104 has a base, and the pipe connector 104 is fixed on the pipe integration plate 10 by fixing the base in the fixing hole.

[0040] In some embodiments, the pipe integration plate body 100 may include two opposing mounting surfaces. The first through hole 101 and the fixing hole 102 are both formed on these mounting surfaces. The pipe connector 104 and pipes are also fixed to the pipe integration plate 100 via these mounting surfaces. The top surface of the pipe integration plate body 100 is stepped and includes a first top surface 1001, a second top surface 1002, and a first vertical surface 1003 connecting the first top surface 1001 and the second top surface 1002. The height of the first top surface 1001 is higher than that of the second top surface 1002; therefore, the location of the first top surface 1001 is an outward protrusion of the pipe integration plate body 100.

[0041] The connector 103 can be installed on the first top surface 1001. That is, the connector 103 is installed on a piece that protrudes outward from the pipe integration plate body 100, thereby avoiding interference with the pipes installed on the pipe integration plate 10 and making it easier for users to avoid the connector 103 during operation to prevent accidental contact.

[0042] In some embodiments, the pipeline integration board body 100 may further include a second vertical surface 1004 and a third vertical surface 1005 disposed opposite to the second vertical surface 1004. The second vertical surface 1004 is located at one end of the second top surface 1002, and the other end of the second top surface 1002 is connected to the lower end of the first vertical surface 1003. The third vertical surface 1005 is located at one end of the first top surface 1001, and the other end of the first top surface 1001 is connected to the upper end of the first vertical surface 1003.

[0043] See also Figure 6 and Figure 7 The connector 103 is made of a non-insulating material. In some embodiments, it can be a copper block, which has good conductivity to connect the water passage and the cable. Understandably, other conductive materials besides copper, such as aluminum, can also be used; further understandably, composite connectors 103 can also be used, such as connectors 103 with an internal structure made of materials such as copper, aluminum, or tin, and an external structure made of insulating material. The connector 103 is mounted on the first top surface 1001 and can be used to connect circuits, water passages, and water-cooled cables, enabling the water-cooled cables to be energized and circulated. The water-cooled cable can be mechanically and electrically connected to the plasma welding torch head, thereby supplying power to the plasma welding torch head and providing water cooling, allowing the plasma welding torch head to maintain good operating conditions.

[0044] In some embodiments, the connector 103 may include a connector body 1030 and mounting holes 1031, second through holes 1032, and fixing holes 1033 formed on the connector body 1030. The mounting hole 1031 is located on the bottom surface of the connector body 1030 and can fix the connector 103 to the first top surface 1001. In some embodiments, there are two mounting holes 1031 spaced apart to prevent the connector 103 fixed to the first top surface 1001 from becoming unstable. It is understood that the number of mounting holes 1031 is not limited to two; three or more are also applicable, and it can also be set to one, in which case the mounting hole 1031 can be an oblong hole, etc.

[0045] The second through hole 1032 is disposed on the side of the connector body 1030 and penetrates the connector body 1030, and can be used to connect pipelines. In some embodiments, the second through hole 1032 may include a first end 1032a located on two opposite sides of the connector body 1030 and a second side 1032b opposite to the first end 1032a. The first end 1032a can be used to connect a cooling water circuit, and the second end 1032b can be used to connect a water-cooled cable. The water-cooled cable is centrally conductive, and the outer insulating tube has an annular space for cooling water to flow through. The cooling water circuit can connect to the annular space through the second through hole 1032, thereby providing cooling water to the water-cooled cable. After the cooling water enters the plasma welding torch, it cools the welding torch and, under the combined action of the plasma gas, compresses the arc to generate a plasma arc with higher energy density.

[0046] In some embodiments, the second through hole 1032 can be a threaded hole, which facilitates the fixing of the pipeline. It only requires the pipeline connector to be connected to it through the thread, which is very convenient. Understandably, the second through hole 1032 can also be set as a straight hole, and its connection with the pipeline can be reinforced by means of fasteners such as locking fasteners.

[0047] The bottom surface of the connector body 1030 also includes a fixing hole 1033. In some embodiments, the fixing hole 1033 may be a threaded hole with a bolt for connecting a cable and fixing the cable to the connector body 1030. The connector body 1030 becomes conductive due to the cable fixed in the fixing hole 1033, thereby energizing the water-cooled cable installed on the second end 1032b, and thus supplying power to the plasma welding torch head. It is understood that when the connector 103 is arranged in a composite configuration, the cable fixed in the fixing hole 1033 should be electrically connected to the conductive portion of the connector 103, and the water-cooled cable installed in the second through hole 1032 should also be electrically connected to the conductive portion.

[0048] The protective panel assembly 20 is installed on the side of the pipe integration plate body 100 and can be used to protect the user's safety and prevent the user from being electrocuted due to accidental contact with the connector 103. In some embodiments, the protective panel assembly 20 may include a partition 201, a cover plate 202, and a cover plate support plate 203. The partition 201 is installed on the third vertical surface 1005, and the cover plate support plate 203 is installed on the first vertical surface 1003; the upper end of the partition 201 is flush with the upper end of the cover plate support plate 203, and the cover plate 202 can be connected to the pipe integration plate 10 through the upper ends of the partition 201 and the upper ends of the cover plate support plate 203, respectively, and covers the connector 103.

[0049] In some embodiments, the width of the partition 201, the cover 202, and the cover support plate 203 is much larger than the size of the connector 103. They cooperate with each other to form a U-shaped semi-enclosed space. The connector 103 is located in the U-shaped semi-enclosed space, and because of their large width, they effectively prevent accidental touch by the user.

[0050] See also Figure 4 In some embodiments, the partition 201 may include a partition body 2010, mounting holes 2011 disposed on the partition body 2010, and expansion holes 2012 disposed on the partition body 2010 and facing outwards from the U-shaped enclosed space. The mounting holes 2011 are used to fix the partition body 2010 to the third vertical surface 1005. The number of mounting holes can be set to two or more spaced apart, or to one. When set to one, it can be an elongated hole for better fixation of the partition 201. The expansion hole 2012 can be used to connect another pipe integration plate 10. When there are many pipes and expansion is required, another pipe integration plate 10 can be connected through the expansion hole 2012, thus meeting various usage scenarios.

[0051] In some embodiments, the cover plate 202 may include a cover plate body 2020 and mounting holes 2021 disposed on the cover plate body 2020. The mounting holes 2021 are positioned opposite the upper end of the partition plate 201 and / or the upper end of the cover plate support plate 203 to fix the cover plate 202 to the partition plate 201 and the cover plate support plate 203. It is understood that the cover plate 202 can be connected to the partition plate 201 and the support plate 203 through the mounting holes 2021 and fasteners, or it can be connected by adhesive bonding or the like.

[0052] In some embodiments, the cover plate support plate 203 may include a cover plate support plate body 2030 and mounting holes 2031 provided on the cover plate support plate body 2030. The cover plate support plate body 2030 can be fixed to the first vertical surface 1003 through the mounting holes 2031.

[0053] See also Figure 5 In some embodiments, the connecting plate 30 can be installed on the second vertical surface 1004, and can be used to connect the welding machine pipeline integration device 1 and the plasma arc welding machine 2. The connecting plate 30 may include a connecting plate body 300, a mounting groove 301 disposed on the connecting plate body 300, and a first mounting hole 302 and a second mounting hole 303 respectively disposed in and outside the mounting groove 301.

[0054] The thickness of the mounting groove 301 is adapted to the thickness of the pipe integration plate body 100. The pipe integration plate 10 can be installed in the mounting groove 301 to fix the connecting plate 30 to it. Because the thickness of the mounting groove 301 is adapted to the thickness of the pipe integration plate body 100, the connecting plate 30 and the pipe integration plate 10 can be installed together stably. The first mounting hole 302 is located in the mounting groove 301 and can be used to fix the connecting plate 30 and the pipe integration plate 10. The second mounting hole 303 can be used to fix the connecting plate 30 on the plasma arc welding machine 2, thereby realizing a firm connection between the welding machine pipe integration device 1 and the plasma arc welding machine 2.

[0055] See also Figure 8 In some embodiments, the welding machine piping integration device 1 may also include a gas flow meter 40, which is mounted on the partition plate 201 and can be connected to a plasma gas pipeline, such as an argon gas pipeline, mounted on the piping integration plate 10. It can be used to measure the argon gas flow rate in the argon gas pipeline. By measuring the argon gas flow rate, the user can perform welding operations under stable argon gas flow conditions, achieving near-end plasma gas supply, thereby ensuring welding quality and improving the safety index of the nuclear power plant.

[0056] Understandably, the gas flow meter 40 can be installed not only on the partition 201, but also on the cover plate 202 and the cover plate support plate 203, as long as it is close to the plasma welding torch head, it can meet the need to measure the gas flow during the welding operation. Furthermore, it can also be understood that the gas flow meter 40 can be installed on the pipeline integration plate 10.

[0057] In some embodiments, the gas flow meter 40 may include a flow meter body 401 for communication with a gas guide pipe and a mounting bracket 402 mounted on the flow meter body 401. The flow meter body 401 is mounted on the mounting bracket 402 and fixed to the partition 201 by the mounting bracket 402. Specifically, the mounting bracket can be mounted on the partition 201 through the expansion hole 2012.

[0058] The installation of the gas flow meter 40 does not affect the extended function of the partition 201. When multiple welding machine pipeline integration devices 1 are provided, there is always one partition 201 located at the end. The gas flow meter 40 can be installed on the partition 201 located at the end. In some embodiments, the mounting bracket 402 can be a clamp to hold and fix the flow meter body 401.

[0059] Understandably, the gas flow meter 40 can also be fixed directly by the outer shell of the flow meter body 401 without the installation bracket 402; the flow meter body 401 can be fixed by welding, glue connection, fasteners and other methods, which can all meet the requirement of measuring the flow rate of the gas pipeline near the ion welding gun head.

[0060] It is also understandable that, in addition to the gas flow meter 40, other measuring devices or functional components, such as liquid flow meters, ammeters, voltmeters, thermometers and other sensors, can be installed on the expansion hole 2012 on the partition 201 to achieve high-quality welding.

[0061] It is understood that the above embodiments only illustrate some implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
