Description

Technical Field

[0001] The utility model relates to the technical field of boiler steel structures, in particular to a boiler steel structure support platform. Background Art

[0002] The boiler steel structure support platform is a structural facility that plays a key role in the industrial field. It is mainly used to support and stabilize boiler equipment to ensure its stability and safety during operation. This support platform is usually constructed of high-strength steel and has excellent load-bearing capacity and durability.

[0003] The waste heat boiler is large in size, requiring workers to install it with the assistance of an external structure. During the boiler's shutdown period, oxygen in the water film reacts with iron to form rust, which can easily cause corrosion in the boiler. This inevitably affects the performance of the waste heat boiler when it is used again, so an external structure is also needed to assist maintenance personnel in carrying out inspections. Furthermore, the existing waste heat boiler steel structure connection platform, used in conjunction with the fixed-size waste heat boiler, occupies a large area.

[0004] The transferred patent of China with the number CN217635572U discloses a steel structure support platform for a waste heat boiler, including a support mechanism I, a telescopic mechanism I, a telescopic mechanism II, a support mechanism II, a maintenance platform, and a staircase; the support mechanism I is arranged at the bottom and one side of the waste heat boiler; the telescopic mechanism I and the telescopic mechanism II are each provided with a pair, the two ends of the telescopic mechanism I are connected to the telescopic mechanism II, and the tops of the telescopic mechanisms I and II are connected to the bottom end of the support mechanism I; there is a pair of support mechanisms II, the support mechanism II is arranged on the inner side of the telescopic mechanisms I and II, and the support mechanism II is arranged below the waste heat boiler; the maintenance platform is arranged above the support mechanism I; the staircase is provided on one side of the maintenance platform. This utility model can adjust the size to install waste heat boilers of different sizes, and at the same time save space.

[0005] In response to the above problems, existing patents have provided solutions. However, the above solutions have certain limitations during use. The two sides of the bottom of the boiler are supported by a support mechanism. Due to the thermal expansion and contraction caused by the vibration and temperature changes during the operation of the boiler, and the uneven force on the support column, micro cracks will appear inside the support column and gradually expand, which is prone to fatigue cracks.

[0006] Therefore, a boiler steel structure support platform is proposed. Utility Model Content
