Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to a support device for a two-stage energy saver. Background Technology

[0002] Boilers in boiler rooms are typically equipped with a secondary economizer to preheat ambient temperature demineralized water. This heated demineralized water is then supplied to the deaerator for boiler feedwater, thereby improving the boiler's thermal efficiency. The secondary economizer is usually located at the end of the boiler flue and requires overhead support.

[0003] In existing technologies, to meet structural strength requirements, the support for secondary energy-saving devices generally adopts a scheme of four columns plus a frame platform. However, the four-column support scheme occupies more ground space, and the four columns are distributed in different locations, which is more likely to cause interference with the layout of ground equipment and pipelines.

The two columns are welded to both sides of the steel structure platform and are located at the end of the steel structure platform away from the embedded parts. The columns are used to support the steel structure platform.

[0006] As a preferred technical solution for the secondary energy-saving device support device, the concrete frame beam is also equipped with multiple reinforcing bars and multiple reinforcing steel plates.

Two embedded parts are set, which are spaced apart along the length of the concrete frame beam. The two main longitudinal beams are welded to the two embedded parts respectively. The two ends of the main crossbeams are welded to the ends of the two main longitudinal beams away from the embedded parts respectively.

The upper end surface of the column is not lower than the upper surface of the main longitudinal beam and the main cross beam.

[0009] As a preferred technical solution for the secondary energy-saving device support device, the steel structure platform also includes multiple local reinforcing beams. These multiple local reinforcing beams are arranged between two adjacent support beams and are spaced apart along the length of the support beams.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 1-7As shown, this utility model provides a support device for a secondary energy-saving device, including a concrete frame beam 1, a steel structure platform 2, and two columns 4. The concrete frame beam 1 is cast into the wall, and the concrete steel frame beam is equipped with embedded parts 11. The steel structure platform 2 is used to support the secondary energy-saving device. One end of the steel structure platform 2 is welded to the embedded parts 11, and the steel structure platform 2 is perpendicular to the embedded parts 11. The two columns 4 are welded to both sides of the steel structure platform 2 and are located at the end of the steel structure platform 2 away from the embedded parts 11. The columns 4 are used to support the steel structure platform 2. By casting the concrete frame beam 1 into the wall and setting the embedded parts 11 on the concrete frame beam 1 and welding them to the steel structure platform 2, and by setting two columns 4 at the end of the steel structure platform 2 away from the embedded parts 11, the steel structure platform 2 is supported by the two columns 4 and the concrete frame beam 1. This ensures structural strength while reducing the number of columns 4 and the space occupied on the ground, further ensuring space for the layout of ground equipment and pipelines.

[0036] It should be noted that the construction method related to the pouring of the concrete frame beam 1 onto the wall is existing technology in this field and will not be described in detail here. The concrete steel frame beam in this embodiment is KL1 300×600, Φ8@100 / 200(2), 3Φ22; 3Φ20, G4Φ12 steel bars. That is, the stirrup diameter is 8mm, the stirrup spacing in the reinforced zone is 100mm, the spacing in the non-reinforced zone is 200mm, and the stirrups are two stirrups; the upper steel bars are 3 Φ22 continuous bars, the lower steel bars are 3 Φ20 continuous bars; and each of the two sides is equipped with 2 Φ12 longitudinal structural steel bars. In other embodiments, adaptive adjustments can also be made according to actual needs, which will not be listed one by one here.

[0037] Further, please refer to Figures 2-4 As shown, the concrete frame beam 1 is also provided with multiple reinforcing bars 12 and multiple reinforcing steel plates 13. The reinforcing bars 12 are all perpendicular to the embedded parts 11 and are welded to them. The reinforcing bars 12 penetrate the concrete frame beam 1, and the multiple reinforcing steel plates 13 correspond one-to-one with the reinforcing bars 12. The reinforcing steel plates 13 are welded to the ends of the reinforcing bars 12 away from the embedded parts 11, thereby further strengthening the structural strength at the embedded parts 11 and further ensuring the support effect on the steel structure platform 2. Exemplarily, in this embodiment, the embedded part 11 has dimensions of 300mm × 150mm × 12mm, and the reinforcing bars 12 are Φ14 grade III reinforcing bars. A total of 6 reinforcing bars 12 are provided, distributed in a 2×3 matrix on the embedded part 11. The reinforcing steel plates 13 have dimensions of 80mm × 80mm × 12mm.

[0038] Specifically, such as Figures 1-2As shown, the steel structure platform 2 includes a main crossbeam 22, two main longitudinal beams 21, and multiple supporting crossbeams 23. Two embedded parts 11 are provided, spaced apart along the length of the concrete frame beam 1. The two main longitudinal beams 21 are welded to the two embedded parts 11 respectively. The two ends of the main crossbeam 22 are welded to the ends of the two main longitudinal beams 21 furthest from the embedded parts 11. The multiple supporting crossbeams 23 are spaced apart along the length of the main longitudinal beams 21, with their ends welded to the two main longitudinal beams 21 respectively. The structural strength of the steel structure platform 2 is enhanced by providing multiple supporting crossbeams 23. It should be noted that in this embodiment, the ends of the main longitudinal beams 21 and the ends of the main crossbeams 22 are welded to the columns 4, meaning the weld length between the main longitudinal beams 21, the main crossbeams 22, and the columns 4 is longer, resulting in higher structural strength of the welded joints. In other embodiments, the ends of the main longitudinal beam 21 and the main transverse beam 22 may be welded together first, and then the upper end of the column 4 may be welded to the bottom of the main longitudinal beam 21 and the main transverse beam 22.

[0039] Specifically, in this embodiment, the ends of the two main longitudinal beams 21 furthest from the embedded part 11 are welded to the two columns 4 respectively, and the two ends of the main crossbeam 22 are welded to the two columns 4 respectively. That is, the main longitudinal beams 21 and the main crossbeams 22 are connected by welding through the columns 4. The upper surface of the column 4 is not lower than the upper surface of the main longitudinal beams 21 and the main crossbeams 22. For example, the upper surface of the column 4, the upper surface of the main longitudinal beams 21, and the upper surface of the main crossbeams 22 are flush, or the upper surface of the column 4 is higher than the upper surface of the main longitudinal beams 21 and the main crossbeams 22, so as to ensure sufficient contact between the column 4 and the main longitudinal beams 21 and the main crossbeams 22, ensure the continuity of the weld, and thus ensure the structural strength at the weld joint. In addition, the steel structure platform 2 also includes multiple local reinforcing beams 24, which are arranged between two adjacent supporting crossbeams 23. The multiple local reinforcing beams 24 are spaced apart along the length of the supporting crossbeams 23. The two ends of the local reinforcing beam 24 are welded to two adjacent supporting beams 23, respectively. The local reinforcing beam 24 is used to install the secondary energy-saving device. By setting the local reinforcing beam 24, the structure near the installation position of the secondary energy-saving device is locally reinforced.

[0040] Both the main longitudinal beam 21 and the main transverse beam 22 are made of H-beams or I-beams. In this embodiment, both the main longitudinal beam 21 and the main transverse beam 22 are preferably made of H-beams. The height of the embedded part 11 is not less than the height of the main longitudinal beam 21, and the width of the embedded part 11 is not less than the width of the main longitudinal beam 21. The main longitudinal beam 21 and the embedded part 11 are fully welded together. For example, the height of the embedded part 11 is greater than or equal to the height of the main longitudinal beam 21, and the width of the embedded part 11 is greater than or equal to the width of the main longitudinal beam 21, to ensure the continuity of the weld between the embedded part 11 and the main longitudinal beam 21 and to ensure the structural strength at the weld joint.

[0041] For example, in this embodiment, the main longitudinal beam 21 has a size of 300mm × 150mm, meaning the height of the embedded part 11 is equal to the height of the main longitudinal beam 21, and the width of the embedded part 11 is equal to the width of the main longitudinal beam 21. The main crossbeam 22 has a size of 300mm × 150mm, and the column 4 is made of steel square tubing with a size of 250mm × 250mm × 12mm × 12mm, meaning the width of the column 4 is greater than the widths of the main crossbeam 22 and the main longitudinal beam 21.

[0042] Optionally, a connecting plate 211 is also provided on the main longitudinal beam 21. One end of the connecting plate 211 is welded to the embedded part 11, and the other end is riveted or bolted to the web of the main longitudinal beam 21. By providing the connecting plate 211, during the process of welding the steel structure platform 2 to the embedded part 11, the connecting plate 211 can be welded to the embedded part 11 first, and then the connecting plate 211 can be connected to the main longitudinal beam 21 by riveting or bolting, thereby achieving the pre-positioning of the steel structure platform 2 and ensuring construction accuracy.

[0043] Furthermore, the secondary energy-saving device support device also includes a steel structure passageway 3, which is welded to both sides of the steel structure platform 2. The steel structure passageway 3 includes longitudinal beams 31, transverse beams 32, and reinforcing beams 33. The longitudinal beams 31 are arranged parallel to the main longitudinal beams 21. One end of the transverse beams 32 is welded to the longitudinal beams 31, and the other end is welded to the columns 4. Both ends of the reinforcing beams 33 are welded to the main longitudinal beams 21 and the longitudinal beams 31, respectively. Multiple reinforcing beams 33 are provided, spaced apart along the length of the longitudinal beams 31. By providing steel structure passageways 3 on both sides of the steel structure platform 2, maintenance requirements are met, and the distance between the two columns 4 is reduced by welding the transverse beams 32 to the columns 4, thereby improving the overall structural strength of the secondary energy-saving device support device.

[0044] Optionally, a guardrail 6 is welded to the side of the steel structure walkway 3 away from the steel structure platform 2. The guardrail 6 is composed of multiple uprights 61 and multiple horizontal bars 62 welded together, with some of the uprights 61 welded to the longitudinal beams 31 of the steel structure walkway 3. In this embodiment, the guardrail 6 is at least 1.2m high, effectively preventing maintenance personnel from falling. Patterned plates 5 are installed on both the steel structure platform 2 and the steel structure walkway 3. The patterned plates 5 can be patterned steel plates or patterned aluminum plates.

[0045] Furthermore, a base plate 41 is integrally provided at the base of the column 4. The base plate 41 is located at the lower end of the column 4 and is welded to or integrally formed with the column 4. The base plate 41 is fixedly connected to the ground foundation by multiple fixing bolts 42. Multiple reinforcing plates 43 are also provided between the fixing bolts 42 and the base plate 41, with each reinforcing plate 43 corresponding to one of the fixing bolts 42 to increase the local structural strength at the bolt connection point. In addition, multiple ribs 44 are provided between the column 4 and the base plate 41. The ribs 44 are used to connect the column 4 and the base plate 41 to reduce stress concentration at the connection point. The ribs 44 are integrally formed with the column 4 and the base plate 41, for example, by welding or integral forming.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
