Description

Technical Field

[0001] This utility model belongs to the field of boiler steel structure technology, and specifically relates to a box-section component for boiler steel structure. Background Technology

[0002] Currently, the installation materials for boiler steel structure connection platforms need to be accurately measured and cut according to the specific boiler specifications before installation. However, in the actual installation process, various errors are very likely to occur, making it impossible to accurately install the steel structure materials. In cases of large errors, it may even be necessary to re-cut the installation materials.

[0003] At the same time, when the boiler is working, it starts to heat up to the working temperature. Due to the large temperature difference, the boiler itself will expand and contract. At the same time, due to the liquid inside the boiler, it will also boil violently during the heating process, which will cause the boiler itself to vibrate slightly. The steel structure itself will also sway with the boiler, which can easily lead to the steel structure loosening.

[0004] After searching, it was found that the existing technologies with the above-mentioned situation include a steel structure of a stable boiler steel frame with announcement number CN213334324U; and a steel structure of a stable boiler steel frame with announcement number CN220818095U. The mechanism achieves the purpose of making the steel beam seat more stable by setting up shock-absorbing springs, elastic plates and damping rods. However, its shock-absorbing springs, elastic plates and damping rods are only set at the bottom of the boiler, and the vibration generated by the boiler operation is dispersed in all directions. The solution to this problem is insufficient.

[0005] The applicant has proposed a solution that can support and dampen the sidewalls of a boiler. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a boiler steel structure box section component that can achieve the effects of supporting and buffering shock absorption through the springs on the support beam, the top plate, the fixed frame, and the damping components.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A boiler steel structure box-section component includes a first column, a first crossbeam, a support base, and a support beam. The first column is fixed in a precast foundation pit. The first crossbeam is fixedly connected to the first column at both ends. The support base is fixed on the first column. The support base includes a support plate and a support rib. One end of the support plate is fixedly connected to the first column. The support plate has several through holes. The support rib is located below the support plate and is fixedly connected to the first column and the support plate for support. The two ends of the support beam are fixed to the support plate of the support base by bolts. The fixed position of the support beam can be adjusted by locking the through holes at different positions with bolts, so that the support beam can support the outer wall of the boiler.

[0009] The support beam includes a support plate, a fixed frame, a top plate, a spring, and a damping assembly. The support plate is bolted to a support plate at both ends, and the fixed frame is fixed to the support plate, with a through groove on the fixed frame. The top plate is located within the through groove. A lead screw and a guide shaft are fixedly mounted on the top plate, with the guide shaft slidably connected to the support plate. The lead screw passes through a pre-drilled through hole on the support plate. The damping assembly is located within the fixed frame, with a spring sleeved around its outer ring. The spring contacts the top plate and the support plate, and pushes the top plate outwards from the surface of the fixed frame, achieving a continuous support method where the top plate is first supported, followed by the fixed frame. The base of the damping assembly is fixed to the support plate, and the top of the damping assembly contacts the top plate. The force and distance of the spring pushing the top plate are adjusted and controlled by rotating the bolts on the lead screw.

[0010] Preferably, a second column is provided around the first column, and adjacent second columns are connected and fixed by a diagonal beam and a second crossbeam; the first column and the second column are provided with a fixed beam that is fixedly connected, and the first column is stabilized by the fixed beam and the second column.

[0011] Preferably, the second crossbeam is connected to the second crossbeam by a fixed vertical support plate to stabilize the structure.

[0012] Preferably, a diagonal brace is fixedly connected between the second column and the second crossbeam to ensure structural stability.

[0013] Preferably, a footboard is provided between the first column and the second column, and the two ends of the footboard are fixed to the fixed beam for support and fixation.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] First, in this solution, the two ends of the support plate in the support beam are fixed to the support plate of the support seat by bolts. The position of the support beam can be adjusted by the through holes at different positions on the support plate, so that the support beam can adapt to boilers of different sizes and specifications, and ensure that the fixing frame and top plate on the support beam can effectively support the side wall of the boiler.

[0016] Secondly, the top plate installed on the support beam supports the boiler side wall by spring pushing, which can work with the damping component to achieve a shock absorption effect. The distance the top plate is pushed out by the spring and the spring force can also be controlled by rotating the bolt on the screw. Furthermore, the way the top plate protrudes from the fixed frame realizes the continuous support method of the top plate first and then the fixed frame. In the case of large boiler vibration or when the flexible support of the top plate reaches its limit, the top surface of the fixed frame can stabilize the boiler in time, avoiding premature fatigue of the flexible support method of the top plate and spring, and also avoiding the disadvantage of large sway when using the flexible support.

[0017] This design also includes a second column that works with a fixing beam to assist in fixing the first column, thereby stabilizing the overall structural design and facilitating the support and protection of the boiler. Attached Figure Description
