Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to underwater welding equipment for the blade edge and web of a coke oven spare part. Background Art

[0002] A coke oven is a kiln that produces coke by melting coal. To ensure a tight seal within the oven, preventing air infiltration and the leakage of harmful gases, a knife-edge web is installed on the oven door. Knife-edge webs include frame-shaped blade edges and webs with folded edges. The webs have folded edges all around, with the outer walls of the folds fitting against the inner walls of the blade edges. Welding equipment is required to weld the folded edges to the blade edges. Currently, welding typically involves placing the web on a support plate, placing the blade edge over the web and the support plate, and then welding the blade edge to the web using an argon arc welding torch. During welding, localized heating causes the weld area to heat up. The subsequent cooling process creates a temperature difference between the weld area and the surrounding unheated areas, resulting in thermal stress. This thermal stress can cause structural deformation of the blade-edge web, impacting product quality. Utility Model Content

[0044] Example, see Figure 1~Figure 2 , which is an embodiment of the present invention, proposes an underwater welding equipment for the knife edge and web of coke oven spare parts, including a workbench 1, a water trough 2, a support plate 3, an outer pressure plate 4, an inner pressure plate 5, a longitudinal slide 6, a connecting beam 7, a transverse slide 8, and a welding gun 9. The water trough 2 is arranged on the workbench 1; the support plate 3 is arranged in the water trough 2 for carrying the web 23, and the knife edge 24 is used to be sleeved on the outer periphery of the support plate 3, and the welding point between the web 23 and the knife edge 24 is located below the water surface in the water trough 2; the outer pressure plate 4 is arranged on the water trough for contacting the upper end surface of the knife edge 24 located in the water trough 2; the inner pressure plate 5 is used to be placed on the web 23 in the water trough 2; the longitudinal slide 6 is slidably arranged on the workbench 1, and longitudinal slides 6 are arranged on both sides of the water trough 2; the connecting beam 7 is connected between the longitudinal slides 6 on both sides; the transverse slide 8 is slidably arranged on the connecting beam 7; and the welding gun 9 is arranged on the transverse slide 8.

[0045] In this embodiment, taking the longitudinal slide 6 sliding in the front-to-back direction and the transverse slide 8 sliding in the left-to-right direction as an example, the water trough 2 is arranged longitudinally in the front-to-back direction and widthwise in the left-to-right direction. The water trough 2 is used to hold water and provide a cooling environment. External pressure plates 4 are provided on the left and right sides and the front and back sides of the water trough 2 to apply pressure to the blade edge 24. Internal pressure plates 5 apply pressure to the web 23 to ensure welding quality. A connecting crossbeam 7 supports the transverse slide 8 and welding gun 9. The longitudinal slide 6 is used to adjust the longitudinal (i.e., front-to-back) position of the transverse slide 8 and welding gun 9. The transverse slide 8 is used to adjust the transverse (i.e., left-to-right) position of the welding gun 9. During use, the web 23 is placed on the support plate 3 within the water trough 2, and the blade edge 24 is fitted around the periphery of the support plate 3, ensuring that the weld between the web 23 and the blade edge 24 is below the water surface within the water trough 2. The inner pressure plate 5 is used to fix the position of the web 23, and the outer pressure plate 4 is used to apply a certain amount of pressure to the upper end surface of the knife edge 24 to ensure the stability of the welding position. The longitudinal slide 6 can be used to drive the transverse slide 8 and the welding gun 9 to move in the front-to-back direction to weld the knife edge 24 and the left and right sides of the web 23. The transverse slide 8 can be used to drive the welding gun 9 to move in the left-to-right direction to weld the knife edge 24 and the front and back sides of the web 23. During the welding process, the water in the water tank 2 can cool the welding area, which helps to reduce thermal stress, thereby reducing the probability of structural deformation of the knife edge web and improving the quality of the product. In order to prevent the outer pressure plate 4 from affecting the use of the welding gun 9, the inner end surface of the outer pressure plate 4 is flush with the inner wall of the water tank 2, or is located outside it.

[0046] like Figure 3As shown, two left and right slide rails 25 and a rack 26 are provided at both ends of the workbench 1. The length directions of the slide rails 25 and the rack 26 are arranged along the front-to-back direction, and the rack 26 is located between the left and right slide rails 25. Two left and right sliding sleeves 27 are provided at the bottom of the left and right longitudinal slides 6. The sliding sleeves 27 are slidably connected to the slide rails 25. A rotary drive mechanism and a gear 28 are provided on the longitudinal slide 6. The gear 28 is engaged with the rack 26. The rotary drive mechanism drives the gear 28 to rotate, and the gear 28 moves along the rack 26, thereby driving the longitudinal slide 6 to move forward or backward.

[0047] like Figure 1 As shown, a screw rod 29 is rotatably connected to one side of the connecting crossbeam 7. The length of the screw rod 29 is arranged in the left-right direction. A nut 30 is threadedly connected to the screw rod 29. The transverse slide 8 is connected to the nut 30. Rotating the screw rod 29 can move the nut 30 left or right along the length of the screw rod 29, thereby driving the transverse slide 8 and the welding gun 9 to move left or right synchronously. The connecting crossbeam 7 is also provided with a transverse drive mechanism 31. The transverse drive mechanism 31 is connected to one end of the screw rod 29. The transverse drive mechanism 31 is used to drive the screw rod 29 to rotate, which saves time and effort.

[0048] Further, if Figure 1 and Figure 2 As shown, the apparatus also includes an adjustment block 10 and a locking bolt 11. The outer pressure plate 4 is raised and lowered at the inner end of the adjustment block 10. The adjustment block 10 is provided with a set of adjustment holes 12. All adjustment holes 12 are arranged along the length of the adjustment block 10 and are located outside the outer pressure plate 4. The lower end of the locking bolt 11 passes through the adjustment holes 12 and locks with the sink 2. The adjustment holes 12 on the left and right sides of the adjustment block 10 are arranged in the left-right direction, while the adjustment holes 12 on the front and back sides of the adjustment block 10 are arranged in the front-back direction. By cooperating with the adjustment holes 12 and the locking bolt 11, the position of the outer pressure plate 4 can be adjusted by changing the length of the adjustment block 10 extending into the sink 2 to accommodate welding requirements for blade edges 24 of varying thicknesses. By changing the vertical position of the outer pressure plate 4 on the adjustment block 10, welding requirements for blade edges 24 of varying heights can be accommodated.

[0049] Further, if Figure 1 and Figure 2As shown, the outer pressure plate 4 also includes a first bearing 13 and a first adjustment rod 14. The first bearing 13 is arranged on the outer pressure plate 4. The lower end of the first adjustment rod 14 is rotatably connected to the outer pressure plate 4 by means of the first bearing 13. The upper end of the first adjustment rod 14 is threadedly connected to the adjustment block 10, and the upper end surface of the first adjustment rod 14 is located above the adjustment block 10. During the rotation and lifting process of the first adjustment rod 14, the provision of the first bearing 13 allows the outer pressure plate 4 to be raised and lowered synchronously with the first adjustment rod 14 without rotating with the first adjustment rod 14. By raising and lowering the first adjustment rod 14, the height of the outer pressure plate 4 can be adjusted. After the first adjustment rod 14 stops rotating, the outer pressure plate 4 can stay at the desired height. The structure is simple, the adjustment is convenient and quick, and it saves time and effort.

[0050] Further, if Figure 1 and Figure 2 As shown, the device also includes a protective block 15, which is mounted on the upper surface of the water tank 2. The lower end of the locking bolt 11 is threadedly connected to the protective block 15. This connection is secure and reliable, and assembly and disassembly are quick and easy, saving time and effort. Furthermore, during assembly and disassembly of the locking bolt 11, it does not come into contact with the water tank 2, thus preventing wear and tear on the water tank 2.

[0051] Further, if Figure 1 and Figure 2 As shown, the outer limit plate 16 is also included. The outer limit plate 16 is disposed on the outer pressure plate 4 and is located at the outer end of the outer pressure plate 4. The inner wall of the outer limit plate 16 is used to contact the outer wall of the knife edge 24. By changing the length of the adjustment block 10 extending into the water tank 2, the spacing between the outer limit plates 16 on both sides of the water tank 2 can be changed, thereby meeting the welding requirements of different types of knife edge webs.

[0052] Further, if Figure 1 and Figure 2 As shown, the outer limiting plate 16 and the outer pressure plate 4 are an integrally formed structure, and the outer limiting plate 16 and the outer pressure plate 4 have higher overall strength and better stability.

[0053] Further, if Figure 1As shown, the lifting seat 17, a second bearing 18, and a second adjustment rod 19 are further included. The lifting seat 17 is located below the transverse slide 8, and the welding gun 9 is arranged on the lifting seat 17; the second bearing 18 is arranged on the lifting seat 17; the upper end of the second adjustment rod 19 is threadedly connected to the transverse slide 8, and the lower end of the second adjustment rod 19 is rotatably connected to the lifting seat 17 via the second bearing 18. The second adjustment rod 19 is used to support the lifting seat 17 and the welding gun 9. During the rotation and lifting process of the second adjustment rod 19, the provision of the second bearing 18 allows the lifting seat 17 to be raised and lowered synchronously with the second adjustment rod 19 without rotating with the second adjustment rod 19. By raising and lowering the second adjustment rod 19, the height of the lifting seat 17 can be adjusted, thereby adjusting the height of the welding gun 9. After the second adjustment rod 19 stops rotating, the lifting seat 17 and the welding gun 9 can stay at the desired height. The structure is simple, the adjustment is convenient and quick, and it saves time and effort.

[0054] Further, if Figure 1 As shown, it also includes a positioning longitudinal plate 20, a positioning transverse plate 21, and a guide rod 22. The positioning longitudinal plate 20 is set on the transverse slide 8 and is located below the transverse slide 8. There are positioning longitudinal plates 20 on both sides of the second adjustment rod 19; the positioning transverse plate 21 is connected between the positioning longitudinal plates 20 on both sides and is sleeved on the outer periphery of the second adjustment rod 19; the lower end of the guide rod 22 is connected to the lifting seat 17, and the upper end of the guide rod 22 passes through the positioning transverse plate 21 and is slidably connected to the positioning transverse plate 21. The positioning longitudinal plate 20 is used to fix the position of the positioning transverse plate 21 to ensure that the relative position between the positioning transverse plate 21 and the welding gun 9 is stable. The positioning transverse plate 21 is used to assist in positioning the guide rod 22 to prevent the guide rod 22 from offsetting during the lifting process. The guide rod 22 is used to limit the movement trajectory of the welding gun 9 to ensure that the welding gun 9 moves in a straight line during the lifting process, which can improve the welding accuracy.

[0055] Further, if Figure 1 As shown, there are at least two positioning transverse plates 21, and all positioning transverse plates 21 are arranged in the vertical direction. Multiple positioning transverse plates 21 together play a guiding and limiting role on the guide rod 22, making the guide rod 22 more stable during the lifting process.

[0056] Furthermore, the welding gun 9 and the lifting seat 17 are detachably connected, which facilitates the disassembly, assembly and maintenance of the welding gun 9.
