Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology for waste incineration, specifically to a positioning bracket for welding hanging nails. Background Technology

[0002] In the operation system of a waste incinerator, the water-cooled wall, as a core heat exchange component, directly determines the thermal efficiency and operational safety of the incinerator. The water-cooled wall comprises fins and water-cooled tubes connected to the fins. Wear, corrosion, or other problems in this structure will severely affect the normal operation of the incinerator. Therefore, reliable protective measures are essential, and using mounting plates to protect the water-cooled wall is a widely adopted method in the industry. The specific process of this protection method is as follows: first, hooks are welded onto the fins of the water-cooled wall; then, the protective mounting plate is initially attached using the hooks; subsequently, a self-fluidizing material is used to fill the gap between the mounting plate and the water-cooled wall, thereby completing the fixation of the mounting plate and achieving comprehensive protection of the water-cooled wall.

[0003] However, the crucial step of welding the hangers onto the water-cooled wall fins is highly susceptible to problems. This is because workers must hold the hangers by hand on the fin surface, and factors such as variations in worker hand stability, interference from the arc light during welding, and inconsistent operating benchmarks due to unevenness on the water-cooled wall surface can easily lead to misaligned hangers. Misaligned hangers not only directly cause inaccurate alignment during subsequent mounting, reducing the fit between the mounting plate and the water-cooled wall and affecting the protective effect, but also require workers to remove the misaligned hangers and re-weld them onto the fins. This process not only increases additional labor and time costs but can also damage the water-cooled wall itself due to repeated welding, especially at the connection between the fins and the water-cooling pipes, ultimately reducing the efficiency and quality of the overall protective operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that nails cannot be quickly and vertically welded to water-cooled walls in the prior art, and to provide a positioning bracket for nail welding.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a positioning bracket for welding hanging nails, comprising a positioning plate with one side serving as a top pressing surface, and a first connecting rod and a second connecting rod mounted on the positioning plate; Both the first and second connecting rods are perpendicular to the top pressure surface and extend in opposite directions. The extension ends of the first and second connecting rods are respectively connected to a welding gun and a butt plate, so that the welding gun is aligned with the butt plate; The docking plate can be connected to a hanging pin that works with the welding gun. When pressure is applied to the water-cooled pipe on the top pressure surface, the top pressure surface will form a reference surface that restricts the welding gun and the docking plate, thereby making the hanging pin perpendicular to the fins of the water-cooled wall.

[0006] As a further optimization of the positioning bracket for nail welding of this utility model: the top pressing surface of the positioning plate is a trapezoidal structure that gradually expands toward the docking plate, so as to increase the contact area between the positioning plate and the outer side of the water cooling pipe.

[0007] As a further optimization of the positioning bracket for nail welding of this utility model: two of each of the first and second connecting rods are provided to maintain the stability of the connection between the welding gun and the mating plate.

[0008] As a further optimization of the positioning bracket for hanging nail welding of this utility model: the two first connecting rods are connected to a connecting frame that can be connected to the welding gun. The connecting frame includes a sleeve frame, which is used to fit around the outer periphery of the welding gun. The two sides of the sleeve frame are provided with insertion holes for the first connecting rods to pass through, corresponding to the positions of the first connecting rods. The inner wall of the insertion hole is machined with a screw hole, and a clamping screw is fitted into the screw hole to fix the first connecting rod to the sleeve frame.

[0009] As a further optimization of the positioning bracket for nail welding of this utility model: the positioning plate is provided with an adjustment groove, the opening direction of the adjustment groove is perpendicular to the top pressure surface, a fastening screw is slidably arranged in the adjustment groove, the fastening screw is connected to a receiving block, and the first connecting rod and the second connecting rod are connected together with the receiving block.

[0010] As a further optimization of the positioning bracket for nail welding of this utility model: the second connecting rod is a threaded rod, and the receiving block and the mating plate are both connected and fixed to the second connecting rod by two sets of locking nuts.

[0011] As a further optimization of the positioning bracket for nail welding of this utility model: one end of the first connecting rod passes through the receiving block and is fastened and locked by the mating screw and the washer.

[0012] As a further optimization of the positioning bracket for nail welding of this utility model: a protective sleeve is sleeved on the outer periphery of the first connecting rod. The protective sleeve is made of asbestos rope and can block the welding heat from being transferred to the surface of the first connecting rod.

[0013] As a further optimization of the positioning bracket for nail welding of this utility model: the positioning plate is made of metal, and an insulating layer is provided on the top pressing surface of the positioning plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a positioning plate with a pressing surface to press against the outer periphery of the water-cooled pipe in the water-cooled wall, thus forming a reference surface on the pipe. Subsequently, using a pre-set receiving block on the positioning plate and a second connecting rod perpendicularly positioned thereto, the connecting plate mounted on the extension end of the second connecting rod is perpendicularly aligned with the fins of the water-cooled wall. This allows the connecting plate to precisely align with the positioned hooks, achieving perpendicular positioning with the fins without manual handling. Simultaneously, the first connecting rod on the receiving block connects to the welding gun, effectively supporting the position of the positioning plate and facilitating the operator's grip on the welding gun to smoothly achieve the perpendicular alignment of the hook with the fins. This effectively solves the problems of insufficient positioning accuracy, poor operational convenience, and poor adaptability in existing hook welding operations, significantly improving welding quality and work efficiency.

[0016] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0017] A positioning bracket for welding hooks includes a positioning plate 4 that can press against the outer surface of the water-cooled pipe 1401 in the water-cooled wall 14. One side of the positioning plate 4 pressing against the outer surface of the water-cooled pipe 1401 is the pressing surface. A receiving block 5 is mounted on the positioning plate 4, and a second connecting rod 3 and a first connecting rod 9 extending in opposite directions are installed on the receiving block 5. The extended end of the second connecting rod 3 is connected to a mating plate 2, which can be connected to the positioning hook 1. The mating plate 2 ensures that the welding joint of the mating plate 2 and the welding gun 7 are coaxially aligned, and that the center positions of the mating plate 2 and the positioning plate 4 are aligned. The extended end of the first connecting rod 9 is connected to the welding gun 7, thereby achieving stable support for the positions of the mating plate 2 and the positioning plate 4.

[0018] like Figure 2 and Figure 3As shown, in actual operation, the top pressing surface of the positioning plate 4 first presses against the outer surface of the water-cooled pipe 1401 of the water-cooled wall 14. The thickness of the top pressing surface, supported by the water-cooled pipe 1401, restricts the sliding of the positioning plate 4 in the vertical direction, while the length of the top pressing surface, supported by the water-cooled pipe 1401, restricts its displacement in the horizontal direction, thus forming a stable horizontal surface under the support of the water-cooled pipe 1401. Subsequently, the receiving block 5 and the second connecting rod 3 are adjusted to ensure that the docking plate 2 is precisely perpendicular to the fin plate 1402 of the water-cooled wall 14. Then, through the synergistic action of the first connecting rod 9 and the connecting frame 8, the entire positioning structure is firmly connected to the welding gun 7. Finally, the coaxial alignment of the positioning pin 1 and the welding joint of the welding gun 7 is achieved, thereby replacing the traditional manual operation of holding the positioning pin 1 and completing the precise and stable welding operation of the pin 1, effectively avoiding the accuracy deviation and safety risks caused by manual operation. During the process of the welding gun 7 pressing the top pressure surface against the water-cooled pipe 1401, the welding port of the welding gun 7 will press the hanging nail 1 against the top pressure surface, causing it to slide on the mating plate 2 in the vertical direction of the top pressure surface. In this way, the hanging nail 1 can adapt to the dimensional error of the water-cooled wall 14 within a certain range, ensuring that each hanging nail 1 can be vertically attached to the fin plate 1402, and the welding operation can be carried out smoothly.

[0019] The receiving block 5, as the core intermediate component connecting the positioning plate 4, the second connecting rod 3, and the first connecting rod 9, has two symmetrically distributed mounting positions for assembling the second connecting rod 3 and the first connecting rod 9, respectively. The second connecting rod 3 is precisely positioned at the center of the receiving block 5 to ensure uniform force transmission and positioning accuracy. To accommodate water-cooled pipes 1401 with different outer diameters, the receiving block 5 and the second connecting rod 3 adopt a detachable and adjustable connection structure. Specifically, the second connecting rod 3 uses a screw structure, and is fixed by two sets of locking nuts 11. Operators can adjust the relative connection position of the receiving block 5 and the second connecting rod 3 by tightening or loosening the locking nuts 11, thereby changing the distance between the connecting plate 2 and the positioning plate 4. This allows the bracket to meet the welding positioning requirements of water-cooled pipes 1401 with different outer diameters, improving the equipment's versatility and applicability.

[0020] The positioning plate 4 is a key component for forming a stable welding reference surface. Specifically, the positioning plate 4 is made of metal, and an insulating layer 15 is provided on the top pressing surface of the positioning plate 4 to prevent the current emitted by the welding gun 7 from generating an electric arc between the water-cooled pipe 1401 and the positioning plate 4, thus preventing the positioning plate 4 from being welded to the water-cooled pipe 1401. At the same time, the insulating layer 15 is made of rubber, which not only isolates the electric current but also provides a certain degree of protection to the surface of the water-cooled pipe 1401. The front end of the positioning plate 4 near the docking plate 2 can be used to press down on two adjacent water-cooled pipes 1401 of the water-cooled wall 14, ensuring the stability of the reference surface through two-point support. In view of the problem that the existing positioning plate 4 has a small contact area with the water-cooled pipe 1401 and is prone to unstable support, this embodiment designs the side of the positioning plate 4 facing the docking plate 2 as a gradually expanding trapezoidal structure. The structure at the front end of the positioning plate 4 can significantly increase the contact area between the positioning plate 4 and the outer side of the water-cooled pipe 1401 of the water-cooled wall 14, effectively disperse the top pressure, improve the stability of the formed horizontal plane, and ensure the perpendicularity of the subsequent docking plate 2 and the fin plate 1402 of the water-cooled wall 14 from the beginning, further improving the positioning accuracy of the hanging nail welding.

[0021] Meanwhile, to accommodate welding guns 7 of different models and specifications, an adjustment groove 10 is provided on the positioning plate 4. The opening direction of the adjustment groove 10 is consistent with the extension direction of the first connecting rod 9 and the second connecting rod 3. A fastening screw 12 is slidably installed in the adjustment groove 10, and the fastening screw 12 is connected to the second connecting rod 3 of the receiving block 5. The operator can flexibly adjust the relative position between the end of the welding gun 7 and the positioning plate 4 by pushing the fastening screw 12 to slide in the adjustment groove 10, thereby facilitating the operator's adjustment so that the receiving block 5 can adjust its position to adapt to different models of welding guns 7, so that the hanging nail 1 connected to the docking plate 2 can stably contact the fin plate 1402 for welding.

[0022] The extension end of the second connecting rod 3 is equipped with a docking plate 2. The docking plate 2 enables the connection and precise positioning of the positioning pin 1. The second connecting rod 3 ensures that the docking plate 2 is coaxially aligned with the welding port of the welding gun 7, and also aligns the center position of the docking plate 2 with that of the positioning plate 4, thus achieving precise matching between the welding path and the positioning position. To further enhance the adaptability of the bracket to different working conditions, the docking plate 2 and the second connecting rod 3 are also connected by two sets of locking nuts 11 for detachable adjustment. Operators can adjust the tightness of the locking nuts 11 to change the distance between the docking plate 2 and the receiving block 5, which can accommodate water-cooled pipes 1401 with different outer diameters and ensure a tight fit between the positioning pin 1 and the fin plate 1402, avoiding welding quality problems caused by distance deviation.

[0023] In actual welding operations, after the positioning plate 4 presses down on the two adjacent water-cooled pipes 1401 to form a stable horizontal plane, the docking plate 2 and the fin plate 1402 of the water-cooled wall 14 can be quickly aligned vertically by the cooperation and adjustment of the receiving block 5 and the second connecting rod 3. At this time, the hanging nail 1 connected to the docking plate 2 will be vertically pressed onto the fin plate 1402, and the hanging nail 1 and the welding port of the welding gun 7 will remain coaxial. This completely replaces the manual hand-held positioning operation, effectively avoiding the inconvenience and accuracy deviation caused by manual operation, and improving welding efficiency and quality stability.

[0024] The extended end of the first connecting rod 9 is connected to the welding gun 7. Its main function is to provide stable support for the butt plate 2 and the positioning plate 4, ensuring that the entire positioning structure does not shift during the welding process and maintaining positioning accuracy. Addressing the safety hazard of overheating near the welding end of the first connecting rod 9 when close to the welding gun 7, which could lead to burns to workers, this embodiment includes a protective sleeve 6 around the outer periphery of the first connecting rod 9. This protective sleeve 6 is woven from asbestos rope and possesses excellent high-temperature resistance and heat insulation properties. It effectively prevents the heat generated during welding from being transferred to the surface of the first connecting rod 9, significantly reducing the risk of burns to workers holding the welding gun 7 and improving operational safety.

[0025] The connection between the first connecting rod 9 and the receiving block 5 is detachable. Specifically, one end of the first connecting rod 9 passes through the receiving block 5 and is then secured and locked using a mating screw 13 and a washer, forming a stable connection structure. Connecting the first connecting rod 9 with screws and washers facilitates disassembly and assembly operations for operators. When the first connecting rod 9 or the receiving block 5 is damaged or worn, it can be quickly replaced individually without requiring the entire equipment to be replaced, significantly reducing maintenance costs and downtime, and improving the economic efficiency of the equipment.

[0026] The first connecting rod 9 is stably connected to the welding gun 7 through the connecting frame 8. The connecting frame 8 firstly ensures the stability of the connection between the first connecting rod 9 and the welding gun 7, avoiding loosening during the welding process. At the same time, the connecting frame 8 allows the operator to move the welding gun 7 while simultaneously moving the entire positioning bracket, enabling continuous welding operations at different positions of the water-cooled wall 14 and improving operational convenience.

[0027] The connecting frame 8 includes a socket 801, which is adapted to the outer circumference of the welding gun 7 to achieve a tight fit. On both sides of the socket 801, corresponding to the installation position of the first connecting rod 9, insertion holes 802 are provided for the first connecting rod 9 to pass through. The inner wall of the insertion holes 802 is machined with screw holes that match the clamping screws 803, used to fix the first connecting rod 9 to the socket 801. During installation, the operator first places the socket 801 around the welding gun 7, then passes one end of the first connecting rod 9 through the insertion holes 802 on both sides of the socket 801, and finally tightens the clamping screws 803. The clamping screws 803 compress the first connecting rod 9, achieving a stable connection between the first connecting rod 9 and the welding gun 7. When disassembly or adjustment is required, simply loosen the clamping screws 803 to separate the first connecting rod 9 from the welding gun 7. The detachable connection structure of the connecting frame 8 not only ensures the stability of the connection between the first connecting rod 9 and the welding gun 7, but also allows for flexible adjustment of the clamping force by adjusting the tightening degree of the clamping screw 803 according to the outer diameter of the welding gun 7, thus adapting to welding guns 7 with different outer diameter specifications and further improving the versatility and applicability of the bracket.

[0028] It should be noted that the specific structure, model specifications and operating mode of the welding gun 7 involved in this embodiment are all within the scope of existing technology. Its working principle is consistent with that of the conventional welding gun 7, and will not be described in detail here.

[0029] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
