Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and specifically relates to a high-strength steel structure engineering installation frame for power plant boilers. Background Technology

[0002] Modern power plant boilers are developing towards larger capacity, higher parameters, and higher efficiency, resulting in a sharp increase in the volume, weight, and operating temperature and pressure of the boiler body. This places high demands on the stability, strength, and precision of the supporting structure to ensure the safety of operators. When the power plant boiler is in operation, the boiler vibrates due to combustion vibration and flue gas flow excitation. Under long-term alternating stress, fatigue cracks may occur at joints and welds, threatening the overall structural safety.

[0003] A search revealed a prior art patent announcement number CN215951368U for a fixed steel structure for a power plant boiler, comprising a boiler, a base damping mechanism, a transverse damping mechanism, and an adjustment mechanism. This boiler steel structure uses multiple sets of support rods I and II within the adjustment mechanism to provide fixed support for the power plant boiler. However, no additional reinforcing structure is provided between support rods I and II, resulting in insufficient vertical support. Given the large size and heavy weight of the power plant boiler, there is a risk of tipping over. Another prior art patent announcement number CN 217979309U for a high-strength boiler steel frame includes a base with a lower fixing groove and a lower spiral hole. This boiler steel structure strengthens the boiler steel frame through a multi-triangular area structure formed by a lower crossbeam and an X-shaped fixing plate. However, the joints of this structure are not reinforced and lack damping structures, causing the boiler to vibrate during operation, posing a risk of cracking and fatigue at the joints. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-strength steel structure engineering installation frame for power plant boilers. By strengthening the connection between the supporting beam I and the supporting column I through the connecting structure, the overall stability of the structure is enhanced, while providing stable support for the working platform. The strengthening structure strengthens the connection between multiple sets of supporting beams I and multiple sets of supporting columns I. At the same time, by strengthening the vibration damping structure within the structure, the vibration generated by the steel structure frame during the operation of the power plant boiler is absorbed, further improving the strength and stability of the steel structure frame. The supporting base fits into the inclined surface of the bottom of the power plant boiler, providing support for the power plant boiler.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The supporting base fits into the inclined surface at the bottom of the power plant boiler to provide support for the power plant boiler.

[0012] The connection structure significantly enhances the connection performance between supporting beam I and supporting column I, thereby improving the stability of the overall structural system and providing a safer and more reliable support foundation for the work platform. The reinforced structure effectively integrates multiple sets of supporting beams I and supporting columns I, forming a synergistic force-bearing system and enhancing overall rigidity and spatial integrity. By incorporating a vibration-damping structure within the reinforced structure, the vibration energy generated by the steel frame during the operation of the power plant boiler can be effectively absorbed, further improving the structure's dynamic response characteristics and enhancing its strength and fatigue stability over long-term use. The support base is designed to fit the inclined surface of the power plant boiler's bottom, providing ample support and further strengthening the overall structural stability.
