Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of boiler maintenance, and in particular relates to a water-cooled wall tube butt adjustment device. Background Art
[0002] The boiler is a major component of thermal power plants. Multiple water-cooled wall pipes are arranged outside the boiler to cool the high-temperature flue gas inside the boiler. Multiple water-cooled wall pipes are arranged vertically and in parallel, and cooling water is introduced into the water-cooled wall. During the operation of the boiler, if a water-cooled wall leaks, the boiler needs to be shut down for emergency repairs, which seriously affects the normal production of power generation. Therefore, water-cooled wall leakage during boiler operation is a major problem that plagues the safe and stable production of thermal power plants. At the same time, during the water-cooled wall maintenance process, the broken pipes need to be remade and the remade pipes need to be re-welded. During the welding process, the pipes need to be butt-jointed to ensure the welding quality.
[0003] At present, the commonly used docking method in water-cooled wall welding operations relies on manual adjustment. Manual adjustment can only be performed before welding. During the welding process, the hands are too close and easy to cause injuries. In addition, the accuracy of manual docking is insufficient. Therefore, it is necessary to provide a water-cooled wall tube docking adjustment device.
[0004] Prior art CN216326193U discloses a boiler water-cooled wall butt joint alignment tool, including a stress frame, the stress frame is a structure that is connected to the outside and the inside through an opening, a telescopic jacking system is installed on one side of the stress frame, the inner end of the telescopic jacking system extends into the stress frame and is rotatably connected to the front bite clamp located inside the stress frame, and a rear bite clamp corresponding to the position of the front bite clamp is fixed inside the other side of the stress frame, the telescopic jacking system drives the front bite clamp to move to the rear bite clamp until the two water-cooled pipes located between the front bite clamp and the rear bite clamp are concentrically joined and then clamped and fixed, and the notches on the side walls of the front bite clamp and the rear bite clamp are butted to form a weld. The alignment tool solves the drawbacks of unstable and easy deviation of the butt joint of the water-cooled pipe wall welding by manual alignment, and eliminates the risk of welding injuries. However, the tool is not suitable for the water-cooled wall to be repaired. Since there are multiple water-cooled walls to be repaired arranged side by side, the arrangement of the force frame is restricted by the adjacent water-cooled wall tubes, making the tool unusable.
[0005] Therefore, there is an urgent need to provide a water-cooled wall tube docking adjustment device, which is suitable for docking water-cooled wall tubes to be repaired compared to the prior art. Utility Model Content
