Description

Technical Field

[0001] This utility model relates to the field of boiler steel frame technology, and in particular to a high-strength boiler steel frame steel structure. Background Technology

[0002] The boiler steel frame is a crucial component of boiler equipment. Its primary function is to provide stable support for the boiler, ensuring its stability during operation and bearing the weight of the boiler as well as various forces generated during operation. The performance of the boiler steel frame directly affects the boiler's safety and operating efficiency. Therefore, designing and manufacturing high-strength, high-stability boiler steel frames is essential for ensuring the safe operation of boilers. In modern industry, boilers are widely used in power generation, heating, chemical, and pharmaceutical fields. With the development of industrial technology, boiler operating conditions are becoming increasingly demanding, requiring boiler steel frames to not only possess high strength and stability but also excellent shock absorption and buffering capabilities to cope with the vibrations and impacts generated during boiler operation.

[0003] The installation process of boilers with steel frames is relatively complex, requiring multiple steps and tools, which increases installation time and labor intensity. Maintenance and inspection require the disassembly of multiple parts, resulting in high maintenance costs and long downtime. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength boiler steel frame steel structure.

[0005] This utility model is achieved using the following technical solution: a high-strength boiler steel frame steel structure, including a supporting base plate, a supporting frame fixedly connected to the top of the supporting base plate, four supporting frames are provided, threaded grooves are opened at the top of the four supporting frames, threaded rods are threadedly connected to the inner walls of the four threaded grooves, four threaded rods are provided, and rotating sleeves are fixedly connected to the top of the four threaded rods, four rotating sleeves are provided.

[0006] Through the above technical solution, four support frames are evenly distributed on the support base plate, ensuring the uniform distribution of the weight of the entire steel structure and improving overall stability. The top of the support frame is provided with a threaded groove, and a threaded rod is connected by a thread. This connection method is not only firm, but also facilitates installation and disassembly. The threaded rod is connected to the support frame through the threaded groove, ensuring the firmness of the connection. The design of the threaded rod allows the height of the support top plate to be adjusted within a certain range to meet the needs of boiler steel frames of different heights. The rotating sleeve is fixedly connected to the top of the threaded rod and is connected to the support top plate through the connecting column, ensuring the stability and reliability of the transmission.

[0007] As a further improvement to the above solution, the top ends of the four rotating sleeves are connected to connecting posts, and four connecting posts are provided.

[0008] Through the above technical solution, the connecting column is connected to the threaded rod through the rotating sleeve, which firmly fixes the supporting top plate to the support frame. The connecting column is usually made of high-strength material, which can withstand greater pressure and ensure the stability of the entire steel structure.

[0009] As a further improvement to the above solution, a supporting top plate is fixedly connected to the top of the four connecting columns.

[0010] Through the above technical solution, the supporting top plate provides top support for the entire steel structure, ensuring that the entire device remains stable during operation.

[0011] As a further improvement to the above solution, a buffer spring is fixedly connected to the bottom end of the supporting top plate. Four buffer springs are provided, and the bottom ends of the four buffer springs contact the top ends of the four support frames. A damper is provided inside the four buffer springs. Four dampers are provided, and the top ends of the four dampers are fixedly connected to the bottom end of the supporting top plate. The bottom ends of the four dampers contact the top ends of the four support frames.

[0012] Through the above technical solution, a buffer spring and a damper are fixedly connected to the bottom of the supporting top plate, which can effectively absorb the vibration and impact force generated during boiler operation, reduce the impact on the steel structure, and extend the service life of the steel structure. The design of the buffer spring also plays a role in protecting the supporting top plate and support frame, reducing fatigue damage caused by vibration. The damper further enhances the shock absorption effect, ensuring that the steel structure can still remain stable under high-frequency vibration. The damper can effectively reduce the noise generated by vibration and improve the comfort of the operating environment.

[0013] As a further improvement to the above solution, an annular limiting plate is fixedly connected to the top of the supporting base plate, and an X-shaped fixing plate is fixedly connected to one end of the four supporting frames that are close to each other, and four X-shaped fixing plates are provided.

[0014] Through the above technical solution, the annular limiting plate is fixedly connected to the top of the support base plate, which can effectively restrict the movement of the support frame, ensure that the support frame remains stable during operation, and prevent displacement caused by external forces. The X-shaped fixing plate is set between the four support frames, which enhances the connection strength between the support frames and further improves the stability of the entire steel structure. The design of the X-shaped fixing plate not only enhances the structural strength, but also reduces deformation caused by external forces, ensuring the stability of the steel structure when operating under high load.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides stable bottom support for the entire steel structure through a supporting base plate. Four support frames are evenly distributed on the supporting base plate to ensure the stability of the entire steel structure. An X-shaped fixing plate is set between the four support frames to enhance the connection strength between the support frames and further improve the stability of the entire steel structure.

[0017] The top of each of the four support frames has a threaded groove, which connects the four threaded rods. This connection method is not only strong, but also easy to install and disassemble. The top of each of the four threaded rods is fixedly connected to a rotating sleeve, and the top of the rotating sleeve is connected to a connecting column. This design ensures high strength and flexibility of the connection.

[0018] This utility model features four buffer springs fixedly connected to the bottom of a supporting top plate, with dampers installed inside each spring. This double buffer design effectively absorbs vibrations and impacts generated during boiler operation, reducing the impact on the steel structure and extending its service life.

[0019] The annular limiting plate is fixedly connected to the top of the support base plate, which can effectively restrict the movement of the support frame, ensure that the support frame remains stable during operation, and prevent displacement caused by external forces.
