Description

Technical Field

[0001] This utility model relates to the field of boiler technology, specifically to a deformation-resistant support bracket for welding boiler water-cooled walls. Background Technology

[0002] A boiler is a device used to heat water and convert it into steam, widely used in power, chemical, and heating industries. Its basic principle is to heat water to boiling point by burning fuel or utilizing other heat sources, generating steam to drive turbines, provide heating, or for other industrial applications. In the boiler's structure, the water-cooled wall is an important component, typically consisting of a series of interconnected pipes. Its main function is to transfer the heat generated inside the boiler to the water, converting it into steam at a high temperature.

[0003] The welding process of boiler water-cooled walls is crucial to ensuring the structural integrity and safety of the water-cooled walls. During welding, the quality of the process directly affects the durability and reliability of the water-cooled walls. In practice, adjacent pipes need to be securely connected by welding to ensure the stable operation of the boiler under high temperature and high pressure. However, after long-term use, the welded joints may be affected by various factors, such as vibration and external forces, leading to deformation or fatigue, which can cause weld cracks or even breakage. This will seriously affect the safety and efficiency of the boiler.

[0004] To address this issue, we propose an anti-deformation support bracket for boiler water-cooled wall welding. This bracket effectively supports the weld joint, reducing stress concentration caused by external forces and vibrations, thereby lowering the incidence of welding cracks and extending the boiler's service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The anti-deformation support bracket for the welded boiler water-cooled wall includes two fixing components respectively installed on two adjacent water-cooled walls. The fixing components include a first clamp and a second clamp. The first clamp and the second clamp are pressed against the outer wall of the water-cooled wall by locking members to form a bidirectional constraint fixing structure.

The first U-shaped limiting blocks of the two fixed components are connected by a first connecting rod. The first connecting rod is used to rigidly connect the first U-shaped limiting blocks of the two fixed components, thereby fixing the relative position of the two fixed components and thus preventing the two adjacent water-cooled walls from being separated or misaligned by external forces.

[0009] The second clamp has a second connecting protrusion at both ends, and a second U-shaped limiting block at the top of the second connecting protrusion. The second U-shaped limiting blocks of the two fixing components are connected by a second connecting rod.

The rectangular limiting hole is used to form an anti-rotation fit with the rectangular positioning block of the locking member. The outer wall of the first connecting rod is in contact with the inner wall of the first U-shaped limiting block. The rectangular limiting hole is connected to the docking hole a.

[0015] Preferably, the top of the second U-shaped limiting block is provided with a circular hole c, the outer wall of the second connecting rod is in contact with the inner wall of the second U-shaped limiting block, and the circular hole c is connected to the docking hole b.

[0016] Preferably, the locking component includes a threaded rod that passes through all the connecting holes to achieve axial fastening. The bottom end of the threaded rod is provided with a rectangular positioning block, which is located in a rectangular limiting hole.

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0031] The anti-deformation support bracket for the welded boiler water-cooled wall includes two fixing components 100 respectively installed on two adjacent water-cooled walls. The fixing component 100 includes a first clamp 110 and a second clamp 120.

[0032] The first clamp 110 has a first connecting protrusion 111 at both ends of its convex surface, and a first U-shaped limiting block 112 at the bottom of the first connecting protrusion 111. The first U-shaped limiting blocks 112 of the two fixing components 100 are connected by a first connecting rod 200. The first connecting rod 200 is used to rigidly connect the first U-shaped limiting blocks 112 of the two fixing components 100, thereby fixing the relative position of the two fixing components 100 and preventing the two adjacent water-cooled walls from being separated or misaligned by external forces.

[0033] The second clamp 120 has a second connecting protrusion 121 at both ends of its convex surface. The top of the second connecting protrusion 121 has a second U-shaped limiting block 122. The second U-shaped limiting blocks 122 of the two fixing components 100 are connected by a second connecting rod 300. The second connecting rod 300 cooperates with the first connecting rod 200 to ensure the stability of the two fixing components 100.

[0034] The first connecting protrusion 111, the first U-shaped limiting block 112, the first connecting rod 200, the second connecting protrusion 121, the second U-shaped limiting block 122, and the second connecting rod 300 are connected by a locking member 400, which is used to achieve axial fastening of multiple structures.

[0035] In this embodiment, the concave surface of the first clamp 110 is provided with a first rubber pad 130, and the concave surface of the second clamp 120 is provided with a second rubber pad 140.

[0036] Specifically, the bottom of the first connecting protrusion 111 is provided with a round hole a1111, which is used for the vertical through-positioning of the locking member 400. The bottom of the first connecting rod 200 and near the left and right ends are provided with mating holes a201, which are connected to the round hole a1111 and are used to form a coaxial mating channel with the round hole a1111.

[0037] Furthermore, a circular hole b1211 is provided at the bottom of the second connecting protrusion 121, and a docking hole b301 is provided at the bottom of the second connecting rod 300 near both the left and right ends. The docking hole b301 communicates with the circular hole b1211, and the docking hole b301 is used to form a composite positioning hole system with the circular hole b1211.

[0038] Furthermore, a rectangular limiting hole 1121 is provided at the bottom of the first U-shaped limiting block 112. The rectangular limiting hole 1121 is used to form an anti-rotation fit with the rectangular positioning block 411 of the locking member 400.

[0041] Furthermore, the top end of the threaded rod 410 passes through the round hole a1111, the mating hole a201, the round hole b1211, the mating hole b301 and the round hole c1221 in sequence and is threadedly connected to a wing nut 420. The wing nut 420 is used to provide clamping force and enable quick assembly and disassembly.

[0042] In this embodiment, the anti-deformation support bracket for the boiler water-cooled wall welding is used by first installing two fixing components 100 on the outer walls of two adjacent water-cooled wall pipes. After the first clamp 110 and the second clamp 120 are wrapped around the pipes, the two ends of the first connecting rod 200 are passed through the two first U-shaped limiting blocks 112, and the two ends of the second connecting rod 300 are passed through the two second U-shaped limiting blocks 122.

The mating hole b301 of the 300 and the round hole c1221 of the second U-shaped limiting block 122 are inserted and positioned by aligning the rectangular positioning block 411 at the bottom of the threaded rod 410 with the rectangular limiting hole 1121 of the first U-shaped limiting block 112. Then, the wing nut 420 is manually tightened until the first rubber pad 130 and the second rubber pad 140 generate a preset clamping force with the outer wall of the pipe. At this time, the first clamp 110 and the second clamp 120 form a two-way constraint and fixing structure. The first connecting rod 200 and the second connecting rod 300 achieve rigid connection through the multi-dimensional limiting effect of the U-shaped limiting block, and finally complete the axial fastening and circumferential anti-rotation locking of the two fixing components 100.
