Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present invention provides a front roller support of a soot blower, as Figures 1-4 shown, the front roller support of the soot blower includes: a mounting plate 1; two threaded rods 2, both of the two threaded rods 2 are threadedly mounted on the mounting plate 1; an adjusting plate 3, the adjusting plate 3 is threadedly sleeved on the two threaded rods 2; two support frames 7, the two support frames 7 are respectively rotatably mounted on the two threaded rods 2, and the two support frames 7 are respectively in sliding contact with both sides of the mounting plate 1 and the adjusting plate 3; a plurality of fixing brackets 4, the plurality of fixing brackets 4 are respectively mounted on the bottom of the mounting plate 1 and the top of the adjusting plate 3, and a limiting wheel 5 is rotatably mounted on each of the plurality of fixing brackets 4, and a soot blower pipe 6 is provided between the plurality of limiting wheels 5; a driving assembly, the driving assembly is arranged at the bottom of the adjusting plate 3, and the driving assembly is used to assist in adjusting the distance between the plurality of limiting wheels 5.

[0022] In this embodiment, the threaded rod 2 serves as a transmission element for lifting the adjusting plate 3 and also serves as the rotating shaft of the support frame 7. The adjusting plate 3 can move up and down along the threaded rod 2 to adjust the height of the inner diameter of the entire support structure to adapt to soot blower pipes 6 of different specifications. The support frame 7 provides a stable support structure to prevent the adjusting plate 3 from tilting during the lifting process. The fixing frame 4 is used to install the limiting wheels 5. The limiting wheels 5 not only support the soot blower pipe 6 but also reduce the friction through their rolling while maintaining the straightness and stability of the pipe. Through the combined design of the threaded rod 2, the adjusting plate 3, the support frame 7, and the limiting wheels 5, the soot blower pipe 6 is effectively supported and limited to prevent it from shaking or shifting during the movement process, improving the stability of the overall structure.

[0023] In a further preferred embodiment of the present utility model, the driving assembly includes a mounting frame 9, a fixing plate 11, and two motors 12. The mounting frame 9 is detachably mounted at the bottom of the adjusting plate 3 through fixing bolts 10. The fixing plate 11 is fixed to the bottom of the mounting frame 9. Both of the two motors 12 are fixed to the bottom of the fixing plate 11, and the output shafts of the two motors 12 can be respectively movably connected to the two threaded rods 2.

[0024] In this embodiment, the mounting frame 9 serves as a support platform for the motors 12 and the fixing plate 11, facilitating installation, disassembly, and maintenance. The fixing bolts 10 are used to firmly fix the mounting frame 9 to the adjusting plate 3 to ensure the stability and reliability of the driving assembly, and at the same time facilitate the disassembly of the mounting frame 9 to prevent damage to the motors 12 caused by a high-temperature environment. The fixing plate 11 serves as the installation base for the motors 12 to ensure the stable operation of the motors 12. The motors 12 serve as the power source, driving the threaded rods 2 to rotate by rotating the output shafts, thereby driving the adjusting plate 3 to move up and down along the threaded rods 2 to realize the automatic adjustment of the distance between the limiting wheels 5. The adjustment method driven by the motors 12 is more stable and reliable than manual adjustment, reducing the adjustment errors and instabilities caused by human factors.

[0025] In a further preferred embodiment of the present utility model, limiting blocks 14 are installed at the bottoms of the two threaded rods 2. Two limiting cylinders 13 are rotatably installed on the fixing plate 11. The two limiting cylinders 13 are respectively fixedly connected to the output shafts of the two motors 12, and the two limiting cylinders 13 can be respectively sleeved outside the two limiting blocks 14.

[0026] In this embodiment, the limiting block 14 serves as the limiting reference for the limiting cylinder 13. The limiting cylinder 13 not only transmits the rotational power of the motor 12 to the threaded rod 2, but also ensures a stable connection between the output shaft of the motor 12 and the threaded rod 2 by sleeving on the limiting block 14, preventing relative sliding or misalignment, enhancing the stability and reliability between the connecting components. The stable connection ensures that the power output by the motor 12 can be efficiently and accurately transmitted to the threaded rod 2, thereby driving the lifting movement of the adjusting plate 3 and improving the transmission efficiency.

[0027] In a further preferred embodiment of the present utility model, support rods 15 are fixedly arranged at the tops of the two support frames 7. Clamping plates 16 are hinged on the two support rods 15. Limiting plates 17 are fixedly arranged at the tops of the two threaded rods 2. The two clamping plates 16 can be conveniently clamped on the two limiting plates 17.

[0028] In this embodiment, the support rod 15 serves as a component for connecting and supporting the clamping plate 16. The clamping plate 16 can rotate around the hinge point. The design of the clamping plate 16 allows it to be conveniently clamped on the limiting plate 17, thereby realizing the limitation of the threaded rod 2, increasing the stability of the distance between the mounting plate 1 and the adjusting plate 3, and thus ensuring the stability of the soot blower pipe 6.

[0029] In a further preferred embodiment of the present utility model, connecting plates 8 that can be installed on the inner wall of the boiler are fixedly arranged on the mutually remote sides of the two support frames 7. A battery box is installed at the bottom of the fixing plate 11. A storage battery is arranged in the battery box. The two motors 12 are respectively connected to the battery box through electric wires.

[0030] In this embodiment, the connecting plate 8 is used to firmly install the support frame 7 on the inner wall of the boiler. The battery box is used to accommodate the storage battery and provide power support for the motor 12. By fixing the support frame 7 on the inner wall of the boiler through the connecting plate 8, the overall stability and reliability of the support structure are enhanced, preventing shaking or falling off caused by external forces. Using the storage battery as the power source of the motor 12 eliminates the need for an external power cord, improving the convenience and flexibility of power supply.

[0031] In a further preferred embodiment of the present utility model, both of the two threaded rods 2 are provided with double-threaded segments. The mounting plate 1 and the adjusting plate 3 are respectively located at the threaded segments in different directions. The multiple limiting wheels 5 are distributed in a square array.

[0032] In this embodiment, each threaded rod 2 includes two threaded portions with opposite directions. This design enables the mounting plate 1 and the adjusting plate 3 to be located at threaded segments in different directions respectively, and the relative movement between the two is achieved by rotating the threaded rod 2. The limit wheels 5 distributed in a square array help to evenly support the soot blower pipe 6 and improve its stability. At the same time, the square array also has a certain degree of flexibility and can adapt to pipes with different diameters and shapes.

[0033] In a further preferred embodiment of the present utility model, the mounting plate 1, the two threaded rods 2, the adjusting plate 3, the multiple fixing frames 4, the multiple limit wheels 5, the two support frames 7, the two connecting plates 8, the two limit blocks 14, the two support rods 15, the two clamping plates 16 and the two limit plates 17 are all made of heat-resistant steel. Heat dissipation nets are provided at the bottoms of the two motors 12.

[0034] In this embodiment, the heat-resistant steel material has excellent high-temperature resistance and strength, and can maintain stable physical and chemical properties in high-temperature environments such as boilers, ensuring the long-term stable operation of the support structure. The design of the heat dissipation net helps to increase the air circulation inside the motor 12, reduce the heat generated during the operation of the motor 12, and improve the heat dissipation performance of the motor 12. This is of great significance for preventing the motor 12 from overheating and extending the service life of the motor 12. In a high-temperature environment, if the support structure is deformed or damaged, it may pose a threat to the safe operation of the boiler and the soot blower. Using heat-resistant steel material improves the stability and safety of the support structure in a high-temperature environment.

[0035] In summary, compared with the related art, the present device can perform multi-directional limiting on the soot blower pipe 6 by arranging multiple limit wheels 5, not only achieving the support effect on the soot blower pipe 6, but also reducing the offset and vibration generated during the movement of the soot blower pipe 6, increasing its stability. By setting the driving component to drive the threaded rod 2 to rotate, the distance between the mounting plate 1 and the adjusting plate 3 can be adjusted, thereby adjusting the distance between the multi-point limit wheels 5 to limit and support the soot blower pipes 6 of different specifications, and at the same time facilitating the installation of the soot blower pipe 6. After the adjustment and installation of the present device are completed, the electrical components such as the motor 12 and the battery box can be removed by disassembling the mounting frame 9, preventing dangerous accidents from occurring in the high-temperature environment of the boiler.
