Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of reactor welding equipment, specifically relating to a reactor anti-deformation jacket welding assembly. Background Technology
[0002] In the use of reactors, the jacket can reduce the deformation of the reactor caused by uneven thermal expansion and contraction or excessive stress by distributing the temperature evenly and sharing the stress. It is an important component to ensure the stability of the reactor structure. The welding quality between the jacket and the reactor body directly affects the performance of this function.
[0003] In traditional welding operations, the positioning and movement of the welding torch rely on manual experience and lack stable auxiliary devices. When welding at the curved joint between the jacket and the vessel body, the welding torch is prone to deviation, resulting in defects such as uneven weld beads and inconsistent penetration depth. This makes the joint a weak point, weakens the jacket's anti-deformation effect, and may also increase the risk of deformation of the reactor in subsequent operating conditions due to uneven stress. Utility Model Content
[0004] The purpose of this invention is to provide a welding assembly for a reactor anti-deformation jacket, which can assist in positioning the welding torch by using an L-shaped limiting plate. This improves the stability of the welding torch's movement during the welding process at the joint between the welding torch and the reactor body and the jacket body, reduces the welding torch's deviation, and lowers the difficulty of operation.

[0008] Furthermore, the L-shaped limiting plate includes two straight plates, the ends of which are fixedly connected, and a first moving wheel and a second moving wheel are respectively installed on the inner sides of the two straight plates.
[0009] Furthermore, the adjusting bracket includes an annular sleeve fixedly connected to the connecting bracket, a universal ball is rotatably connected inside the annular sleeve, the welding torch is mounted on the universal ball, and a first locking screw that can abut against the universal ball is threaded onto the annular sleeve.
[0010] Furthermore, a sleeve is fixedly connected to the universal ball, a straight tube is provided on the welding gun, the straight tube is slidably connected inside the sleeve, and a second locking screw that can abut against the straight tube is threaded onto the sleeve.
[0011] The technical effects achieved by this utility model are as follows:
[0012] The present invention provides a reaction vessel anti-deformation jacket welding assembly that uses an L-shaped limiting plate to assist in positioning the welding torch. This improves the stability of the welding torch movement during the welding process at the joint between the welding torch and the reaction vessel body and the jacket body, reduces torch deviation, and lowers the difficulty of operation.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figures 1-4 As shown, a welding assembly for an anti-deformation jacket of a reactor includes an L-shaped limiting plate 1 and an adjusting bracket fixedly connected to the L-shaped limiting plate 1, with a welding torch 13 mounted on the adjusting bracket.
[0021] like Figure 1As shown, during use, the L-shaped limiting plate 1 is placed against the two sides of the corner of the reactor body 15. Then, the position of the welding torch 13 is adjusted by adjusting the bracket so that the welding torch 13 is aligned with the welding joint of the reactor body 15 and the jacket 16. Welding is then performed at the welding joint of the reactor body 15 and the jacket 16. During the welding process, the welding torch 13 is moved outside the assembly of the reactor body 15 and the jacket 16 to adjust the welding position of the welding torch 13. During the movement of the welding torch 13, the L-shaped limiting plate 1 is placed against the corner of the jacket 16 for positioning, which can effectively improve the movement stability of the welding torch 13. Thus, the welding torch 13 can be assisted in positioning by the L-shaped limiting plate 1, improving the movement stability of the welding torch 13 during the welding process of the welding torch 13 at the welding joint of the reactor body 15 and the jacket 16, reducing the deviation of the welding torch 13, and reducing the difficulty of operation.
[0022] like Figures 1-3 As shown, in some embodiments, there are two L-shaped limiting plates 1, and a connecting bracket 7 is fixedly connected between the two L-shaped limiting plates 1. An adjusting bracket is fixedly connected to the connecting bracket 7. The welding gun 13 is positioned by the two L-shaped limiting plates 1, which can effectively reduce the left and right displacement of the welding gun 13 on the jacket body 16.
[0023] like Figures 1-3 As shown, in some embodiments, the L-shaped limiting plate 1 includes two straight plates, the ends of which are fixedly connected. The inner sides of the two straight plates are respectively equipped with a first moving wheel and a second moving wheel to reduce the friction between the L-shaped limiting plate 1 and the jacket 16 during the movement of the L-shaped limiting plate 1.
[0024] like Figures 2-3 As shown, the first movable wheel includes a first U-shaped frame 2 fixedly connected to the inner side of the L-shaped limiting plate 1, and a first rotating wheel 3 rotatably connected inside the first U-shaped frame 2. The second movable wheel includes a rotating rod 4 rotatably connected to the inner side of the L-shaped limiting plate 1, and a second U-shaped frame 5 fixedly connected to one end of the rotating rod 4. A second rotating wheel 6 rotatably connected inside the second U-shaped frame 5. At this time, the second U-shaped frame 5 can rotate on the L-shaped limiting plate 1 by rotating the rotating rod 4.
[0025] Meanwhile, the second rotating wheel 6 can be a cylindrical structure or a spherical structure, and the second rotating wheel 6 is preferably a spherical structure, which can cooperate with the rotation of the rotating rod 4 to move better on the upper side of the jacket body 16.
[0026] Among them, such as Figures 2-4As shown, the adjusting bracket includes an annular sleeve 8 fixedly connected to the connecting bracket 7. A universal ball 9 is rotatably connected inside the annular sleeve 8. The welding torch 13 is mounted on the universal ball 9. The angle of the welding torch 13 can be changed by rotating the universal ball 9. A first locking screw 11 that can abut against the universal ball 9 is threaded on the annular sleeve 8. The universal ball 9 can be locked and unlocked by rotating the first locking screw 11.
[0027] In some implementations, the welding torch 13 is directly fixedly connected to the universal ball 9.
[0028] like Figures 2-4 As shown, in some other embodiments, a sleeve 10 is fixedly connected to the universal ball 9, and a straight tube 14 is provided on the welding torch 13. The straight tube 14 is slidably connected inside the sleeve 10, thereby adjusting the distance between the end of the welding torch 13 and the welding joint of the reactor body 15 and the jacket body 16. A second locking screw 12 is threadedly connected to the sleeve 10 and can abut against the straight tube 14. The straight tube 14 can be locked and unlocked by rotating the second locking screw 12.
[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
