Description

Technical Field

[0001] This utility model relates to the field of boiler wall temperature monitoring technology, and specifically to an integrated mounting bracket for a boiler wall temperature monitoring device. Background Technology

[0002] As core power and heating equipment in industries such as power, chemical, and metallurgy, the operational safety and service life of boilers directly affect the stability and economic efficiency of the entire production system. The boiler furnace and its heating surface pipes operate under extreme high-temperature and high-pressure environments for extended periods. The wall temperature of its metallic materials is a critical parameter for monitoring equipment health and preventing safety accidents. If the wall temperature of critical components such as superheaters and reheaters exceeds the material's allowable limits, it will lead to a sharp increase in the creep rate of the steel, a decrease in effective strength, and ultimately, catastrophic accidents such as pipe bulging, cracking, or even pipe rupture. Therefore, real-time and accurate monitoring of boiler wall temperature is the lifeline for achieving predictive maintenance and ensuring safe and economical operation.

[0003] Currently, in industrial practice, the mainstream installation method for boiler wall temperature monitoring devices (usually thermocouples or resistance temperature detectors) involves selecting a measuring point on the boiler's heated surface tube wall and then directly fixing the sensor or its matching connector to the tube wall using welding. While this welding method provides a relatively secure connection for a certain period, its inherent technical drawbacks become increasingly apparent with long-term equipment operation and technological advancements. As a precision instrument, the boiler wall temperature monitoring device inherently requires periodic calibration and replacement in case of damage. Simultaneously, the boiler itself also requires periodic shutdowns for maintenance. With welding, the sensor and boiler tube wall form a "permanent" connection. Any disassembly inevitably relies on destructive methods such as cutting (e.g., gas cutting), and after maintenance or repair, re-welding must be performed in or near the original location. This process is not only cumbersome and time-consuming, leading to extended equipment downtime, but also places extremely high demands on the skills of operators, requiring the intervention of specialized welding professionals, significantly increasing labor and time costs. Furthermore, repeated cutting and welding can cause irreversible damage to the boiler base material, creating new stress concentration points and potentially weakening the pipe structure's strength. Moreover, once the welding position is determined, it cannot be changed, and the sensor's final measurement posture is also fixed. When the boiler undergoes technical upgrades, or when operational data reveals that the original measuring point location is not representative, the monitoring points cannot be optimized or adjusted, limiting the effectiveness and guiding significance of the monitoring data. Additionally, due to the dense arrangement of pipes on the boiler's heating surface and the complex spatial structure, it is difficult to ensure an ideal fit or precise distance between the sensor probe and the pipe wall during welding operations. Minor angles or poor contact may exist, introducing measurement errors and affecting data accuracy. Currently, the welding fixing method commonly used in boiler wall temperature monitoring devices, while providing a secure connection, suffers from a series of inherent drawbacks, including difficult disassembly and maintenance, high costs, inability to adjust measuring points, and difficulty in guaranteeing installation accuracy, leading to large measurement errors. Utility Model Content

[0006] Furthermore, the adjusting component includes a guide groove installed on the top of the mounting bracket, and a sliding plate is slidably installed inside the guide groove, with one side of the sliding plate connected to one end of the bracket.

[0007] Furthermore, a lead screw is rotatably installed inside the guide groove, a threaded ring is provided inside the sliding plate, the threaded ring is threadedly connected to the lead screw, the upper end of the lead screw passes through the guide groove, and an assist ring is installed at the upper end of the lead screw.

[0008] Furthermore, limit plates are installed on both sides of the sliding plate, and the limit plates are slidably connected to the guide groove.

[0009] Furthermore, a limit bolt is provided on one side of the limiting plate, and the limit bolt is threadedly connected to the guide groove.

[0010] Furthermore, the universal joint has two retaining bolts connected by symmetrical threaded connections on its outer surface.

[0011] Compared with existing technologies, the integrated mounting bracket for a boiler wall temperature monitoring device provided by this utility model adopts a clamping scheme of fixed retaining ring, movable retaining ring and connecting bolt, which realizes quick disassembly and convenient maintenance, avoids cutting and welding operations, shortens maintenance time, reduces operation difficulty and maintenance costs, and can be adapted to monitoring devices of different specifications within a certain size range, improving the applicability and economy of the bracket.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] As attached Figure 1 To be continued Figure 4 As shown:

[0021] This utility model provides an integrated mounting bracket for a boiler wall temperature monitoring device, including a mounting frame 1. An adjusting component is provided at the upper end of the mounting frame 1. A bracket 8 is installed at the front end of the adjusting component. A universal joint 9 is installed at the front end of the bracket 8. A connecting ring 11 is installed at the front end of the universal joint 9. A fixing ring 12 is installed at the front end of the connecting ring 11. A connecting plate 14 is installed at both ends of the fixing ring 12. A connecting plate 2 15 is abutted at one end of each of the two connecting plates 14. A movable ring 13 is installed between the two connecting plates 2 15. The connecting plates 14 and 2 15 are connected by a connecting bolt 16. The boiler wall temperature monitoring device is fixed between the fixing ring 12 and the movable ring 13.

[0022] Currently, boiler wall temperature sensors are mostly fixed to the boiler wall by welding. Welding results in a permanent connection between the sensor and the boiler wall. When maintenance, replacement or calibration of the sensor is required, it must be cut and re-welded. The operation is cumbersome and time-consuming. In addition, the welding position is fixed and the angle or position of the sensor cannot be adjusted, making it difficult to adapt to different monitoring needs or changes in boiler structure.

[0023] The integrated mounting bracket of this application, through modular design and adjustable structure, enables rapid disassembly and flexible positioning of the boiler wall temperature monitoring device.

[0024] By welding the mounting bracket 1 to the boiler wall, the universal joint 9, installed at the front end of the bracket 8, provides multi-degree-of-freedom rotation during the installation and adjustment of the temperature monitoring device. This allows the connecting ring 11 and subsequent components to be flexibly adjusted in angle, ensuring optimal contact or observation position between the monitoring device and the boiler wall surface. It adapts to irregular wall surfaces. The fixed retaining ring 12 and the movable retaining ring 13 form an openable and closable annular structure through connecting plate one 14 and connecting plate two 15. The connecting bolt 16 passes through connecting plate one 14 and connecting plate two 15. By tightening or loosening the connecting bolt 16, the opening and closing degree between the movable retaining ring 13 and the fixed retaining ring 12 can be controlled, thereby clamping or releasing the boiler wall temperature monitoring device. This retaining ring design allows for quick installation and disassembly without welding and is adaptable to monitoring devices of different sizes.

[0025] This application adopts a clamping scheme of fixed retaining ring 12, movable retaining ring 13 and connecting bolt 16, which realizes quick disassembly and convenient maintenance, avoids cutting and welding operations, shortens maintenance time, reduces operation difficulty and maintenance costs, and can adapt to monitoring devices of different specifications within a certain size range, improving the applicability and economy of the bracket. Secondly, through the two-stage adjustment mechanism of adjusting parts and universal joint 9, the position and angle of the monitoring device can be adjusted with multiple degrees of freedom, which can adapt to various boiler structures and monitoring requirements, with strong versatility, providing flexible adjustment capabilities and excellent adaptability.

[0026] In one embodiment of this utility model, the outer surface of the universal joint 9 is symmetrically threaded with two fixing bolts 10.

[0027] Specifically, after adjusting the temperature monitoring device to a suitable position, the universal joint 9 is fixed by the fixing bolt 10, thereby securing the temperature monitoring device.

[0028] In one embodiment of the present invention, the adjusting member includes a guide groove 2 installed on the top of the mounting bracket 1, a sliding plate 3 is slidably installed inside the guide groove 2, and one side of the sliding plate 3 is connected to one end of the bracket 8.

[0029] A lead screw 6 is rotatably installed inside the guide groove 2. A threaded ring is provided inside the sliding plate 3. The threaded ring is threadedly connected to the lead screw 6. The upper end of the lead screw 6 passes through the guide groove 2. An auxiliary ring 7 is installed on the upper end of the lead screw 6.

[0030] Limiting plates 4 are installed on both sides of the sliding plate 3, and the limiting plates 4 are slidably connected to the guide groove 2.

[0031] A limit bolt 5 is provided on one side of the limit plate 4, and the limit bolt 5 is threadedly connected to the guide groove 2.

[0032] Specifically, the rotating booster ring 7 drives the lead screw 6 to rotate within the guide groove 2. Since the sliding plate 3 forms a lead screw and nut pair with the lead screw 6 through its internal threaded ring, the rotational motion of the lead screw 6 is converted into linear motion of the sliding plate 3 along the direction of the guide groove 2, thereby driving the entire front-end bracket 8 and monitoring device to rise and fall, realizing fine adjustment of the vertical position of the temperature monitoring device.

[0033] After the monitoring device is positioned to the target location through the above adjustments, the limiting bolt 5 is installed, with its end spirally screwed into the side of the guide groove 2. The resulting frictional force rigidly locks the sliding plate 3 and its associated components to the guide groove 2, preventing displacement caused by boiler operating vibrations and ensuring the long-term stability and reliability of the monitoring point.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
