Description

Technical Field

[0001] The present invention relates to the technical field of boiler manufacturing, and in particular to a weld detection device and a weld detection method for a module tube panel. Background Art

[0002] Waste heat boiler is a boiler that uses the waste heat from waste gas, waste materials or waste liquid in various industrial processes and the heat generated by the combustion of combustible materials to heat water to a certain temperature. Waste heat boiler mainly includes module tube panel, such as Figure 1 As shown, the modular tube panel is assembled by welding two-end cylinders and multiple layers of branch pipes. Because the butt welds of the modular tube panel are primarily located in the narrow space between the branch pipe layers, and because the tube panel is long, has low rigidity, and is difficult to rotate, weld inspection of the modular tube panel has become a technical challenge in this field.

[0003] Currently, existing weld inspection devices primarily utilize X-ray imaging systems. Typically, an X-ray machine is placed above the workpiece under test, with a flat-panel detector positioned below. During inspection, the X-ray machine projects X-rays onto the workpiece, while the flat-panel detector receives the X-ray information and digitizes it into an image signal. However, existing X-ray imaging systems are only suitable for inspecting single-layer welds on workpieces and are not suitable for inspecting multiple layers of welds on modular tube panels.

[0004] Therefore, there is an urgent need for a weld detection device for a modular tube panel to solve the above problems. Summary of the Invention

[0062] Figure 1 FIG. 1 shows a schematic structural diagram of the module tube panel 100 provided in this embodiment. Figure 1 As shown, the modular tube panel 100 includes a cylindrical body 101 and branch tube groups 102. The branch tube groups 102 extend along a first direction, with the cylindrical body 101 welded to both ends of the branch tube groups 102 in the first direction. The branch tube groups 102 include multiple branch tubes spaced apart along a second direction, with several branch tube groups 102 spaced apart in parallel along the vertical direction. It should be noted that the first direction is the length of the modular tube panel 100, the second direction is the width of the modular tube panel 100, and the vertical direction is the arrangement direction of the branch tube groups 102, which is also the vertical direction within the space during the inspection process.

[0063] Figure 2 Shown Figure 1 The enlarged view of point A in the middle. Figure 2 As shown, the modular tube panel 100 provided in this embodiment has four layers of branch pipe groups 102, each layer of which contains multiple branch pipes. Of course, in other embodiments, the number of branch pipe groups 102 is not limited to four layers, and can be any number of two or more layers, which will not be illustrated here one by one.

[0064] Figure 3 FIG. 1 shows a schematic structural diagram of the weld detection device for the module tube panel provided in this embodiment. Figure 3 As shown, the modular tube panel weld inspection device includes a shielding chamber 1, an X-ray module 3, a conveying module 2, a bottom-layer flat-panel detection module 4, and an interlayer flat-panel detection module 5. The X-ray module 3, the bottom-layer flat-panel detection module 4, and the interlayer flat-panel detection module 5 are all located within the shielding chamber 1. The conveying module 2 is used to transport the modular tube panel 100 into the shielding chamber 1. The bottom-layer flat-panel detection module 4 cooperates with the X-ray module 3 to complete weld inspection of the branch pipe group 102 on one layer of the modular tube panel 100. The interlayer flat-panel detection module 5 cooperates with the X-ray module 3 to complete weld inspection between two adjacent branch pipe groups 102 on the modular tube panel 100.

[0065] Preferably, the weld detection device further includes an image processing software system for processing X-ray images formed by the bottom flat panel detection module 4 and the interlayer flat panel detection module 5, so as to facilitate workers to detect weld quality.

[0066] Continue as Figure 3 As shown, the conveying module 2 includes a conveying mechanism 21 and a conveying frame 22. The conveying frame 22 is used to carry the modular tube panels 100, and is provided with a clearance space corresponding to the welds to be inspected on the modular tube panels 100. The conveying mechanism 21 is used to drive the conveying frame 22 to move in a first direction. Specifically, the conveying mechanism 21 is placed on the ground, and the conveying frame 22 carries the modular tube panels 100 and moves under the conveyance of the conveying mechanism 21. The conveying frame 22 is a frame structure that can not only carry the modular tube panels 100, but also has a clearance space corresponding to the welds of the modular tube panels 100, so that the X-ray module 3 and the underlying flat panel detection module 4 can cooperate to complete the weld inspection of the modular tube panels 100. Optionally, the conveying mechanism 21 can be a conveying roller mechanism.

[0067] Continue as Figure 3 As shown, the protection chamber 1 has an entrance and an exit at both ends in the first direction, and a conveying mechanism 21 is provided at both ends in the first direction. The conveying mechanism 21 is capable of conveying a conveyor rack 22 from the entrance into the protection chamber 1 and from the exit out of the protection chamber 1. For ease of description, the opening on the right side of the protection chamber 1 is defined as the entrance, and the opening on the left side of the protection chamber 1 is defined as the exit. The conveying mechanism 21 on the right side of the protection chamber 1 conveys the conveyor rack 22 and the modular tube panels 100 thereon into the protection chamber 1 for testing. After testing is completed, the modular tube panels 100 are removed from the protection chamber 1 for welding of the next layer of branch pipe groups 102 or conveyed to the next workstation.

[0068] Continue as Figure 3As shown, the protection room 1 includes an entrance transition room 11, a detection room 12, and an exit transition room 13.

By providing the entrance transition room 11 and the lead curtains 14 therein, as well as by providing the exit transition room 13 and the lead curtains 14 therein, X-rays can be prevented from causing harm to the staff. For example, there are three lead curtains 14 in the entrance transition room 11, and the three lead curtains 14 are spaced apart along the first direction. There are three lead curtains 14 in the exit transition room 13, and the three lead curtains 14 are spaced apart along the first direction. Of course, in other embodiments, the number of lead curtains 14 can be designed as needed and is not limited here.

[0069] Continue as Figure 3 As shown, the protective chamber 1 also includes an entrance door that can automatically open and close the entrance. The protective chamber 1 also includes an exit door that can automatically open and close the exit. Optionally, the entrance door is liftably disposed at the entrance of the protective chamber 1 via a motor-screw assembly. The exit door is liftably disposed at the exit of the protective chamber 1 via a motor-screw assembly. Of course, in other embodiments, the entrance and exit doors can also be raised and lowered using other linear lift drive mechanisms.

The output end of the ray deflection drive mechanism 35 is used to mount the ray swing drive mechanism 36 and drive the ray swing drive mechanism 36 to rotate about the first direction. The output end of the ray swing drive mechanism 36 is used to mount the X-ray machine 31 and drive the X-ray machine 31 to rotate about the second direction. Such an arrangement enables the bottom flat panel detector 41 to move in the first direction, the second direction and the vertical direction, as well as to rotate around the first direction and around the second direction, thereby facilitating adjustment of the irradiation angle of the X-ray machine 31 and thereby more accurately aligning and detecting the weld.

[0072] Continue as Figure 4 As shown, the first ray translation drive mechanism 32 includes a ray translation guide rail 321, a first ray mounting frame 322 and a first ray driving assembly 323. The first ray mounting frame 322 is slidably mounted on the ray translation guide rail 321 along the second direction.

The ray rack 3233 is mounted on the ray translation guide 321 and extends in the second direction. The ray gear 3232 meshes with the ray rack 3233. When the first ray driver 3231 drives the ray gear 3232 to rotate, the ray gear 3232 and the ray rack 3233 cooperate to enable the first ray mounting frame 322 to move in the second direction relative to the ray rack 3233. For example, a servo motor can be used for the first ray driver 3231.

[0074] Continue as Figure 4 As shown, the second ray translation drive mechanism 33 includes a second ray mounting frame 331 and a second ray drive assembly 332. The second ray drive assembly 332 can be a servo motor screw linear drive mechanism or a motor belt linear drive mechanism.

The ray bracket 341 is installed on the second ray mounting frame 331, the ray lifting frame 342 is installed on the ray bracket 341 so as to be liftable in the vertical direction, and the ray lifting drive assembly 343 is installed on the ray bracket 341. The output end of the ray lifting drive assembly 343 is connected to the ray lifting frame 342 for driving the ray lifting frame 342 to move up and down.

[0076] The radiation lift drive mechanism 34 also includes a radiation guide assembly 344, which comprises a slidably mated radiation guide rod 3441 and a radiation guide sleeve 3442. The radiation guide sleeve 3442 is fixed to the radiation bracket 341, and the radiation guide rod 3441 extends vertically and is fixed to the radiation lift frame 342. There are at least two radiation guide assemblies 344. Exemplarily, there are four detection guide assemblies 444, which are arranged around the detection lift frame 442.

Figure 5 Combine Figure 4 As shown, the ray lifting drive assembly 343 includes a ray lifting driver 3431, a ray lifting driving gear 3432, a ray lifting driven gear 3433, a ray screw 3434, and a ray connecting seat 3435. The ray lifting driving gear 3432 and the ray lifting driven gear 3433 are meshed, the ray screw 3434 is drivingly connected to the ray lifting driven gear 3433, the ray connecting seat 3435 is threadedly connected to the ray screw 3434, and the ray lifting frame 342 is mounted on the ray connecting seat 3435. The ray lifting driver 3431 drives the ray lifting driving gear 3432 to rotate, so that the ray lifting driven gear 3433 drives the ray screw 3434 to rotate, and then the ray connecting seat 3435 drives the ray lifting frame 342 to move vertically. For example, the ray lifting driver 3431 can be a servo motor.

[0078] Continue as Figure 5 Combine Figure 4 As shown, the ray deflection drive mechanism 35 includes a deflection cylinder 351 and a deflection drive assembly 352. The deflection cylinder 351 is rotatably mounted on the ray lifting frame 342 about a first direction. The X-ray machine 31 is mounted within the deflection cylinder 351.

[0101] This embodiment further provides a method for detecting welds of a modular tube panel, which is based on the above-mentioned device for detecting welds of a modular tube panel to detect the bottom layer and interlayer welds of the modular tube panel 100 and improve detection efficiency.

Figure 13 Schematic diagram showing the improved weld detection method of this embodiment Figure 3 . Figure 14 Schematic diagram showing the improved weld detection method of this embodiment Figure 4 .like Figure 11-14 As shown, the weld detection method of the module tube panel includes the following steps:

[0103] S100, see Figure 11 , the first layer branch pipe group 102 ( Figure 11 The bottom branch pipe group 102 is welded to the cylinder 101 to form a layer of modular tube panels; the position to be inspected of the layer of modular tube panels is transported to the protection room 1; the bottom flat panel detector 41 cooperates with the X-ray machine 31 to complete the weld inspection of the layer of modular tube panels;

[0104] S200, see Figure 12 , weld the second layer branch pipe group 102 to the cylinder 101 to form a two-layer modular tube panel; transport the two-layer modular tube panel to be inspected into the protection room 1; insert the interlayer flat panel detector 51 between the first and second layer branch pipe groups 102, and cooperate with the X-ray machine 31 to complete the weld inspection of the two-layer modular tube panel;

[0105] S300, see Figure 13 , weld the third-layer branch pipe group 102 to the cylinder 101 to form a three-layer modular tube panel; transport the position to be inspected of the three-layer modular tube panel to the protection room 1; insert the interlayer flat panel detector 51 between the second and third-layer branch pipe groups 102, and cooperate with the X-ray machine 31 to complete the weld inspection of the three-layer modular tube panel;

[0106] S400, see Figure 14 , weld the fourth-layer branch pipe group 102 to the cylinder 101 to form a four-layer modular tube panel; transport the position to be inspected of the four-layer modular tube panel to the protection room 1; insert the interlayer flat panel detector 51 between the third and fourth-layer branch pipe groups 102, and cooperate with the X-ray machine 31 to complete the weld inspection of the four-layer modular tube panel.

[0107] It's worth noting that, for the sake of convenience in describing the inventive concept of the inspection method, the modular tube panels 100 formed by welding two or more layers are referred to as interlayer modular tube panels. During weld inspection, the interlayer modular tube panels are transported to the location to be inspected within the protective chamber 1. The interlayer flat panel detector 51 is inserted between two adjacent layers of branch pipe groups 102 and, in conjunction with the X-ray machine 31, completes weld inspection of the interlayer modular tube panels 100. Figure 11-14In the example, the branch pipe group 102 of the module tube panel 100 is four layers. When the number of layers of the branch pipe group 102 is other numbers, the operation can be repeated as needed until the welding and inspection of the branch pipe groups 102 of all layers are completed. No further examples will be given here.

[0108] Furthermore, after the interlayer flat panel detector 51 is inserted between two adjacent layers of branch pipe groups 102, the starting position and the end position of the weld detection are sequentially set along the second direction. The interlayer flat panel detector 51 and the X-ray machine 31 start to perform weld detection in sequence from the starting position until the weld detection of one layer of the interlayer module pipe panel 100 is completed at the end position. Specifically, the starting position and the end position of the interlayer flat panel detector 51 can be set by the control system to realize automatic control of the interlayer flat panel detector 51. During the detection process, the X-ray machine 31 starts to emit X-rays and irradiates the weld to be detected. After the interlayer flat panel detector 51 receives and converts it into a graphic signal, it continues to detect the next weld to be detected on the same layer after the professional determines the detection.

[0109] Preferably, outside the protection chamber 1, multiple branch pipes are sequentially welded to the cylinder 101 along the second direction to form a layer of branch pipe group 102. When inspection is required, the conveying frame 22 and the modular tube panel 100 thereon are conveyed to the protection chamber 1 by the conveying mechanism 21 for weld inspection.

After the inspection is determined by professionals using graphic software, the X-ray machine 31 and the bottom flat panel detector 41 are synchronously translated to inspect the next weld on the same layer. Until the inspection of all welds on the same layer is completed, the modular tube panel 100 is completely transported out of the protective room 1 by the conveyor frame 22, and the conveyor frame 22 is removed to carry out the welding of the next layer.

[0111] Specifically, in step S200, the second-layer branch pipe group 102 of the modular tube panel 100 is welded and docked, and then hoisted onto the conveyor frame 22 on the entrance side. The conveying mechanism 21 drives the conveyor frame 22 to move, transporting the modular tube panel 100 into the protective chamber 1. The weld moves to the inspection position, and the interlayer flat panel detection module 5 is partially inserted into the narrow space between the first and second layers. After placement, a starting point is set, and the interlayer flat panel detector 51 and the X-ray machine 31 are synchronously moved to the weld position. The X-ray machine 31 is turned on to inspect the workpiece through radiography. The interlayer flat panel detector 51 receives and converts the signal into a graphic signal. After the inspection is determined by professionals using graphic software, the X-ray machine 31 and the interlayer flat panel detector 51 are synchronously moved to inspect the next weld on the same layer until all welds on the same layer are inspected. After the interlayer flat panel detection module 5 is withdrawn from between the first and second layers, the modular tube panel 100 is completely transported out of the protective chamber 1 via the conveyor frame 22 and removed from the conveyor frame 22 for docking the weld on the next layer.

[0112] Specifically, in step S300, the third-layer branch pipe group 102 of the modular tube panel 100 is welded and docked, then hoisted onto the conveyor rack 22 at the entrance side. The conveyor mechanism 21 drives the conveyor rack 22 to move, transporting the modular tube panel 100 into the protective chamber 1. The weld moves to the inspection position, and the interlayer flat panel detection module 5 is partially inserted into the narrow space between the second and third layers. After placement, a starting point is set, and the interlayer flat panel detector 51 and the X-ray machine 31 are synchronously moved to the weld position. The X-ray machine 31 is turned on to inspect the workpiece through radiography. The interlayer flat panel detector 51 receives and converts the signal into a graphic signal. After the inspection is determined by professionals using graphic software, the X-ray machine 31 and the interlayer flat panel detector 51 are synchronously moved to inspect the next weld on the same layer until all welds on the same layer are inspected. After the interlayer flat panel detection module 5 is withdrawn from between the second and third layers, the modular tube panel 100 is completely transported out of the protective chamber 1 via the conveyor rack 22 and removed from the conveyor rack 22 for docking the weld on the next layer.

[0113] Specifically, in step S400, the fourth-layer branch pipe group 102 of the modular tube panel 100 is welded and docked, then hoisted onto the conveyor rack 22 at the entrance side. The conveyor mechanism 21 drives the conveyor rack 22 to move, transporting the modular tube panel 100 into the protective chamber 1. The weld moves to the inspection position, and the interlayer flat panel detection module 5 is partially inserted into the narrow space between the third and fourth layers. After placement, a starting point is set, and the interlayer flat panel detector 51 and the X-ray machine 31 are synchronously moved to the weld position. The X-ray machine 31 is turned on to inspect the workpiece through radiography. The interlayer flat panel detector 51 receives and converts the signal into a graphic signal. After the inspection is determined by professionals using graphic software, the X-ray machine 31 and the interlayer flat panel detector 51 are synchronously moved to inspect the next weld on the same layer until all welds on the same layer are inspected. After the interlayer flat panel detection module 5 is withdrawn from between the third and fourth layers, the modular tube panel 100 is completely transported out of the protective chamber 1 via the conveyor rack 22 and removed from the conveyor rack 22 for docking the weld on the next layer.

[0114] When the number of layers of the branch pipe group 102 is greater than four, repeat the previous steps and insert the interlayer flat panel detection module 5 between the layers to complete the multi-layer detection.
