Description

Technical Field

[0001] This invention relates to the field of gas storage tank technology, and in particular to a gas storage tank production line. Background Technology

[0002] A gas storage tank is a device specifically used to store gas and also serves to stabilize system pressure. Depending on the pressure it can withstand, gas storage tanks can be classified as high-pressure gas storage tanks, low-pressure gas storage tanks, and atmospheric pressure gas storage tanks. The manufacture of gas storage tanks usually requires rolling and welding steel plates to form a cylindrical tank.

[0003] In the current technology, gas storage tanks are usually welded on the production line. However, during welding, the welding torch may not be able to be aligned with the weld seam. If welding is then carried out, the weld seam may not be able to be sealed properly, thus affecting the quality of the tank. Summary of the Invention

[0004] To address the problem that in the existing technology, when welding gas storage tanks, the welding torch is often misaligned with the weld seam, which can easily lead to incomplete welds and affect the quality of the tank, this application provides a gas storage tank production line.

[0005] A gas storage tank production line includes a transport assembly for transporting sheet metal. Along the transport assembly are sequentially arranged an uncoiling assembly, a leveling assembly, a cutting assembly, a handling assembly, a coiling assembly, and a welding assembly. The uncoiling assembly is used to uncoil steel, the leveling assembly is used to flatten the steel, the cutting assembly is used to cut the steel, the coiling assembly is used to coil the steel into a cylindrical tank, and the welding assembly is used to weld the seams of the tank.

[0006] A gap alignment component is also provided between the weld assembly and the coil assembly. The gap alignment component includes an infrared sensor. A rotation component is also provided at the gap alignment component. The rotation component is used to rotate the steel. When the infrared sensor detects a gap, the steel is fed into the weld assembly.

[0007] By adopting the above technical solution, sheet steel is usually rolled on the unwinding assembly. After being fed out, the leveling assembly can flatten the previously rolled steel and then cut it by the cutting assembly. The cut steel is in sheet form. The sheet steel can then be rolled up to form a cylindrical can. However, since there are still some gaps between the rolled steel, these gaps need to be welded. At this time, an infrared sensor is used to detect the distance. If the distance is large, it is a gap; if the distance is small, it is not aligned with the gap. If it is not aligned, the rotating assembly can rotate the can to align it. After the gap is detected, welding can be carried out, reducing the possibility of misalignment and failure to weld tightly, which would affect the quality of the can.

[0008] Optionally, the gap alignment assembly further includes a frame, the infrared sensor is fixedly mounted on one end of the frame near the rotating assembly, the welding assembly is mounted on the other end of the frame, and a transport assembly is also mounted on the frame.

[0009] The frame has a feeding inlet corresponding to the shape of the tank. The conveying component includes a slide rail, which is arranged along the length of the frame and corresponds to the position of the feeding inlet. A sliding seat is slidably connected to the slide rail, and the sliding seat slides along the length of the slide rail. Multiple support claws for abutting against the inner wall of the tank are fixedly arranged on the sliding seat. The support claws are arc-shaped and can be assembled into a circle. The support claws are slidably connected to the sliding seat. A drive cylinder for driving the support claws is also provided on the sliding seat.

[0010] By adopting the above technical solution, a feeding inlet is opened on the tank body, which can transport the rotated tank body along the frame and support it with the support claws to restrict the rotation of the tank body and allow the tank body to slide during transportation. This reduces the situation where the gaps on the tank body cannot be aligned again due to the rotation of the tank body during transportation, further reduces the situation where the gaps on the tank body cannot be aligned, reduces the situation where the welds cannot be sealed, and improves the quality of the product.

[0011] Optionally, the transport assembly further includes a plurality of guide rods arranged along the length of the frame and used to abut against the outer wall of the tank.

[0012] By adopting the above technical solution and setting multiple guide rods, the guide rods can abut against the tank body, and the guide rods can cooperate with the support claws to clamp the tank body, reducing the situation where the tank body is pried open by the support claws and the gap is widened, further reducing the situation where the gap cannot be welded tightly, thereby improving the quality of the tank body.

[0013] Optionally, a support frame is provided on the frame corresponding to the guide rod. The support frame is slidably connected to the frame and is also provided with a locking element for limiting the displacement of the support frame.

[0014] By adopting the above technical solution and setting up a support frame that can be slidably adjusted, the position of the guide rod can be adjusted by adjusting the support frame when transporting tanks of different sizes, so that the guide rod can abut against tanks of different sizes.

[0015] Optionally, the frame body is provided with a feed outlet on the side near the weld assembly. The feed outlet is positioned corresponding to the slide rail and the shape of the tank. The weld assembly includes a welding torch, which is fixedly mounted on the frame body. The weld assembly also includes a guide frame, which is located on the side of the frame body away from the slide rail. The guide frame is axially arranged around the feed outlet, and multiple rotating rollers are rotatably mounted on the guide frame. The rotating rollers are used to abut against the outer wall of the tank body.

[0016] By adopting the above technical solution, a feeding outlet is set up, and a guide frame is set up at the feeding outlet. The guide frame can assist in feeding the tank by rotating rollers when the tank is fed out, reducing the friction when the tank is fed out, improving the feeding efficiency, and also improving the stability of the tank during welding and improving the welding quality.

[0017] Optionally, the guide frame located on the lower side of the tank is slidably connected to the frame, while the other guide frames are fixedly connected to the frame. A push cylinder is also provided on the frame corresponding to the guide frame on the lower side of the tank, and the piston rod of the push cylinder is fixedly connected to the corresponding guide frame.

[0018] By adopting the above technical solution, and setting up a guide frame with corresponding sliding wheels to push the cylinder, it is possible to adjust when the tank size changes, thus making it suitable for tanks of more sizes. It can also clamp the tank, reducing the possibility of inaccurate welding caused by the rotation of the tank during welding, and further improving the welding quality.

[0019] Optionally, a guide ring is fixedly provided on the guide frame that is fixedly connected to the frame body. The guide ring is set to correspond to the position and shape of the tank and allows the tank to pass through.

[0020] By adopting the above technical solutions and setting up guide rings, the guide rings can guide the tank body, reduce the possibility of deviation during transportation that could affect welding, and also reduce the possibility of tank body offset when being delivered, thereby improving the stability during transportation.

[0021] Optionally, a plug gauge is provided on the frame corresponding to the outlet position. The plug gauge is located between the outlet and the inlet. A sandpaper layer is detachably connected to the plug gauge and is used to abut against the gaps in the tank body.

[0022] By adopting the above technical solutions, the plug gauge can detect the size of the gap, ensuring that the size of the gap after compression during welding meets the welding requirements, thereby making the weld at the gap tighter. A removable sandpaper layer is also installed on the plug gauge, which can clean impurities at the gap, making the gap tighter during welding. When the sandpaper layer is damaged, it can be removed and reinstalled, reducing the possibility that the sandpaper layer cannot clean impurities.

[0023] Optionally, the frame is equipped with a pressure sensor corresponding to the plug gauge. The pressure sensor is fixedly connected to the plug gauge and is used to detect the force on the plug gauge and control the operation of the welding torch.

[0024] By adopting the above technical solution and setting a pressure sensor, it is possible to detect whether the plug gauge comes into contact with impurities. When the pressure is high, it indicates that the impurities are difficult to clean or that a cutting problem has occurred. Therefore, the tank needs further processing before it can be processed. At this time, the welding torch can stop working, reducing the occurrence of defective products.

[0025] Optionally, two plug gauges and two pressure sensors are provided, with the two plug gauges spaced apart along the length of the frame.

[0026] By adopting the above technical solution, two plug gauges are set up to detect the size of the gap in turn, further determining whether the gap can be compressed to the required size. It can also perform two cleaning of impurities, further reducing impurities during welding. If the plug gauge in the rear position still detects a large pressure, it can be considered that the impurities cannot be cleaned. At this time, the welding gun is stopped and the welding of the tank is stopped.

[0027] In summary, this application has at least the following beneficial effects:

[0028] 1. This application solves the problem that in the prior art, when welding gas storage tanks, the welding torch is often misaligned with the weld seam, which easily leads to incomplete welds and affects the quality of the tank. This application first uses an infrared sensor and a rotating component to rotate the formed tank. The distance the laser of the infrared sensor travels through the gap is significantly greater than when it does not pass through the gap, thus allowing for the detection of the gap. Then, the tank is transported by a conveying component, reducing the possibility of changes in the gap position before welding, thereby reducing the likelihood of incomplete welds.

[0029] 2. This application also uses a plug gauge to detect the size of the gap. While detecting the size of the gap, the plug gauge can also polish the impurities in the gap through a removable sandpaper layer. At the same time, it determines whether to start the welding torch based on the pressure sensor, thereby further improving the welding quality. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-3 The present application will be further described in detail through specific embodiments.

[0041] Example 1

[0042] A gas storage tank production line, such as Figure 1 As shown, the system includes a transport assembly 1 for transporting sheet metal. Along the transport assembly 1, an uncoiling assembly 11, a leveling assembly 12, a cutting assembly 13, a handling assembly 14, a coiling assembly 15, and a welding assembly 2 are sequentially arranged. The uncoiling assembly 11 is used to uncoil steel, the leveling assembly 12 is used to flatten the steel, the cutting assembly 13 is used to cut the steel, the coiling assembly 15 is used to coil the steel into a cylindrical tank, and the welding assembly 2 is used to weld the seams of the cylindrical steel components. In specific implementation, the transport component 1 includes multiple transport frames and transport rollers. The transport rollers are rotatably connected to the transport frames and are equidistantly spaced along the length of the transport frames. The unwinding component 11 includes an unwinding machine, which can continuously release the steel that was just wound on it. The leveling component 12 includes two sets of vertically movable pressing rollers, which can rotate and squeeze the steel to level it and form steel sheets. The cutting component 13 includes a guillotine, which moves up and down under the drive of a hydraulic cylinder to cut the steel sheets. The handling component 14 includes a robotic arm, which can clamp the cut steel sheets, drill holes in them, and re-feed them. The plate rolling component 15 includes a plate rolling machine, which rolls the sheet steel into cylindrical plates using rubber rollers and hard rollers. There are still some gaps between the cylindrical plates, which are then sent to the welding component 2 for welding.

[0043] like Figure 1 and Figure 2 As shown, a gap alignment component 3 is also provided between the weld assembly 2 and the coil assembly 15. The gap alignment component 3 includes an infrared sensor 31, and a rotation component 4 is also provided at the gap alignment component 3. The rotation component 4 is used to rotate the steel. When the infrared sensor 31 detects a gap, the steel is fed into the weld assembly 2. In specific implementation, the infrared sensor 31 detects gaps by detecting distance. When a gap is detected, the distance will be much greater than when no gap is detected, so the gap can be detected by detecting distance. In this embodiment, two sets of weld assembly 2 and gap alignment component 3 are provided.

[0044] like Figure 2 and Figure 3 As shown, the gap alignment assembly 3 also includes a frame 32, an infrared sensor 31 is fixedly installed at one end of the frame 32 near the rotating assembly, the weld assembly 2 is installed at the other end of the frame 32, and a transport assembly 5 is also installed on the frame 32.

[0045] like Figure 2 and Figure 3 As shown, the frame 32 has a feeding inlet 321 corresponding to the shape of the tank. The conveying component 5 includes a slide rail 51, which is arranged along the length of the frame 32 and corresponds to the position of the feeding inlet 321. A sliding seat 511 is slidably connected to the slide rail 51. The sliding seat 511 slides along the length of the slide rail 51 and is embedded in the slide rail 51. Three support claws 512 for abutting against the inner wall of the tank are fixedly arranged on the sliding seat 511. The three support claws 512 are all arc-shaped and can be combined into a circle. The support claws 512 are slidably connected to the sliding seat 511. A drive cylinder 513 for driving the support claws 512 is also provided on the sliding seat 511. The conveying component 5 also includes multiple guide rods 514, which are arranged along the length of the frame 32 and abut against the outer wall of the tank. In practice, the support claw 512, driven by the drive cylinder 513, can abut against the inner wall of the initially formed tank, while the guide rod 514 can abut against the outer wall of the tank. The guide rod 514 and the support claw 512 can cooperate to clamp the tank, so that the tank can be restricted and move with the movement of the sliding seat 511, thereby transporting the tank without rotating it.

[0046] like Figure 2 and Figure 3 As shown, a support frame 322 is provided on the frame 32 corresponding to the guide rod 514. The support frame 322 is slidably connected to the frame 32, and a locking element 323 is also provided on the support frame 322 to limit the displacement of the support frame 322. In specific implementation, the support frame 322 slides with the frame 32 to adjust the position of the guide rod 514. The locking element 323 includes a bolt, which is threadedly connected to the frame 32 to fix the support frame 322.

[0047] like Figure 2 and Figure 3 As shown, the frame 32 has a feed outlet 33 on the side near the weld assembly 2. The feed outlet 33 is positioned corresponding to the slide rail 51 and the shape of the tank. The weld assembly 2 includes a welding torch 21, which is fixedly mounted on the frame 32 and positioned downwards to facilitate welding towards the seam. The weld assembly 2 also includes a guide frame 34, which is located on the side of the frame 32 away from the slide rail 51 and is axially arranged around the feed outlet 33. Multiple rotating rollers 341 are rotatably mounted on the guide frame 34, and the rotating rollers 341 are used to abut against the outer wall of the tank. In practice, the guide frame 34 can guide the tank and simultaneously assist in feeding the tank out through the rotating rollers 341.

[0048] like Figure 2 and Figure 3 As shown, the guide frame 34 located on the lower side of the tank is slidably connected to the frame 32, while the other guide frames 34 are fixedly connected to the frame 32. A push cylinder 35 is also provided on the frame 32 corresponding to the guide frame 34 on the lower side of the tank, and the piston rod of the push cylinder 35 is fixedly connected to the corresponding guide frame 34. In practical implementation, since tanks of different sizes need to be transported, the push cylinder 35 moves the guide frame 34 up and down, adjusting the size of the channel formed by the guide frame 34 and further improving versatility.

[0049] like Figure 2 and Figure 3 As shown, a guide ring 38 is fixedly installed on the guide frame 34, which is fixedly connected to the frame 32. The guide ring 38 is set to correspond to the position and shape of the tank and allows the tank to pass through. In specific implementation, the guide ring 38 is arranged around the tank. By setting the guide ring 38, the tank can be guided, reducing the possibility of the tank tilting when it is delivered.

[0050] Working principle: After the basic molding, there is still a certain gap between the tanks. At this time, the tank is rotated and the gap is detected by infrared sensor 31. When the gap is aligned, the tank is transported to the welding point for welding, which reduces the possibility of the gap not being welded tightly and improves product quality.

[0051] Example 2

[0052] like Figure 4As shown, the main difference between Embodiment 2 and Embodiment 1 lies in Embodiment 2. In Embodiment 2, a plug gauge 36 is provided at the position corresponding to the outlet 33 on the frame 32. The plug gauge 36 is located between the outlet 33 and the inlet 321. A sandpaper layer 361 is detachably connected to the plug gauge 36, and the sandpaper layer 361 is used to abut against the gaps in the tank body. In specific implementation, the sandpaper layer 361 can be detachably connected to the plug gauge 36 by pasting or embedding. By rubbing against the impurities in the gap, the impurities that can be cleaned in the gap can be cleaned. The sandpaper layer 361 can then be replaced. The plug gauge 36 can detect the size of the gap, which can reduce the situation where the welding quality is affected by the gap being too large or too small.

[0053] like Figure 4 As shown, a pressure sensor 37 is fixedly installed on the frame 32 corresponding to the plug gauge 36. The pressure sensor 37 is fixedly connected to the plug gauge 36 and is used to detect the force on the plug gauge 36 and control the operation of the welding torch 21. Two plug gauges 36 and two pressure sensors 37 are provided, spaced apart along the length of the frame 32. In practice, the plug gauge 36 can detect the size of the gap and determine whether it meets the requirements by the pressure. If the pressure is too high, the gap will be pressed too tightly, affecting the shape of the tank. Excessive pressure may also introduce large impurities, affecting subsequent welding. If the pressure is too low, cutting problems may occur, making it impossible to weld the tanks together. The two plug gauges 36 detect the gap sequentially, which can further confirm whether the requirements are met and also perform two cleaning operations. If the plug gauge 36 located at the rear still detects a large pressure, it can be considered that the impurities have not been completely removed. At this time, the welding torch 21 stops working to reduce the occurrence of defective products.

[0054] Working principle: The processing principle is the same as in Example 1, but two sets of plug gauges 36 and pressure sensors 37 are set to detect the size of the gap. At the same time, impurities are cleaned to improve the welding quality. When impurities cannot be cleaned or other cutting problems occur, the welding gun 21 is stopped to reduce the occurrence of defective products.

[0055] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
