Description
TECHNICAL FIELD

[0002] Flue gas produced by the boiler combustion is discharged into the atmosphere through the chimney. The chimney is usually vertical, or as close to vertical as possible, to ensure smooth flow of gas.
[0003] At present, various support and fixation problems will occur under the condition of limited installation space. First, the chimney is directly installed from the top interface of the boiler economizer (coal saving device), and the economizer is a small component, which has limited frame strength and cannot bear the chimney load with high weight.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] like Figures 1-2 As shown, this application relates to a chimney roof support device. Figure 1 As shown, the chimney roof support device includes several sets of base plates 10; each base plate 10 refers to a bottom support plate, which can achieve good fixing and support effects, and at the same time, can achieve good assembly effects with other components, thereby achieving multiple functions. Preferably, there are four base plates 10, which are arranged in pairs opposite each other; this ensures good subsequent assembly effects. More preferably, the base plates 10 are made of high-strength metal, including but not limited to: iron.
[0041] A plurality of columns 20 are respectively and correspondingly arranged on a plurality of base plates 10 along a first direction. The main function of the columns 20 is to transfer the load-bearing capacity of the base plates 10 to the upper structure, providing vertical support for the entire support device. At the same time, by fixing the columns 20 to the base plates 10 along the first direction, a good assembly effect can be achieved, thereby ensuring the stability of the structure. Here, the first direction refers to the vertical direction, which is also the Y-axis direction in the two-coordinate system. Preferably, the number of columns 20 is four, which can achieve a good matching effect with the number of base plates 10, and at the same time, ensure a stable support effect.
[0042] It should be noted that the bottom of the column 20 can be connected to the base plate 10 by bolts; or the column 20 and the base plate 10 can be connected by welding.
[0043] Several support beams 30 are arranged opposite each other on the column 20 along the second direction. By arranging the support beams 30 along the second direction and opposite each other on the column 20, a lateral distribution support function can be achieved, further improving the stability of the structure. At the same time, it also allows for good assembly of other components. Here, the second direction refers to the horizontal direction; it is also the X-axis direction in the two-coordinate system. Preferably, the number of support beams 30 is two.
[0044] Several auxiliary beams 40 are respectively arranged opposite to each other between the support beams 30; by arranging the auxiliary beams 40 between adjacent support beams 30, the overall rigidity and stability of the device can be enhanced. The auxiliary beams 40 are arranged at intervals in the horizontal direction, forming a stable frame structure with the support beams 30. Preferably, there are four auxiliary beams 40, and the four auxiliary beams 40 are arranged in pairs opposite to each other.
[0045] Several fixed beams 50 are obliquely arranged between the support beam 30 and the auxiliary beam 40, respectively; this achieves a good fixed assembly effect. At the same time, the fixed beams 50, by being obliquely arranged, disperse the loads in the lateral and vertical directions, reducing local stress concentration. Preferably, the number of fixed beams 50 is four.
[0046] Several support components 60 are respectively disposed on the fixed beam 50 along the first direction; this can achieve a good support and limiting effect.
[0047] The structure comprises several supporting components 60 that enclose a limiting cavity 70 with open top and bottom ends, thereby supporting and limiting the chimney 90 within the limiting cavity 70. Through the cooperation of the above components, a stable and robust supporting structure is formed, which can effectively withstand the self-weight of the chimney 90 and the loads brought about by the external environment (such as wind, vibration, etc.). At the same time, the limiting cavity 70 enclosed by the supporting components 60 ensures that the chimney 90 can remain vertical within the device and prevents it from shifting or tipping over.
[0048] The roof support device of this application changes the support position and method of the chimney 90, relatively reduces the weight of the chimney 90, solves the problems of fixing and bearing the steel chimney 90, and minimizes the cost of the steel chimney 90.
[0049] As can be seen from the above description, this application achieves the following technical effects:
[0050] In this embodiment, a prefabricated support structure is adopted, in which several support components 60 are enclosed to form a limiting cavity 70 with open upper and lower ends, so that the chimney 90 is supported and limited within the limiting cavity 70, thereby achieving the purpose of limiting and supporting the chimney 90, thus realizing the technical effect of improving structural strength and reducing costs. This solves the problems of the chimney 90 being directly installed from the top interface of the boiler economizer, the economizer being a small component with limited frame strength, which cannot support the weight of the chimney 90; and the lack of a steel frame or steel beam for the chimney 90 to be fixed and supported vertically above (within a certain range) the flue gas equipment; the steel chimney 90 is usually 3-4mm thick, and the higher the chimney 90, the worse its rigidity, which may lead to bending and collapse in the upper space of the boiler room without reinforcement support points, with excessive self-weight and long-term high temperature baking; and the fact that strengthening and thickening the cylinder and enlarging the base of the self-supporting steel chimney 90 would not only increase manufacturing costs but also civil engineering costs.
[0051] Furthermore, the auxiliary beams 40 are detachably connected to each other via connecting components 80. It is understood that by detachably providing connecting components 80 between the auxiliary beams 40, a stable connection can be provided while also being detachable, so as to facilitate the installation, disassembly and subsequent maintenance of the device.
[0052] Furthermore, the connecting assembly 80 includes a connector 801 that penetrates adjacent auxiliary beams 40, and at least one end of the connector 801 is provided with a fastener 802. It is understood that this achieves good assembly results while also facilitating easy assembly and disassembly. The connector 801 can be a connecting stud; the fastener 802 can be a fastening nut.
[0053] Furthermore, a preload is provided on the connector 801 and located between adjacent auxiliary beams 40. It is understood that by providing a preload on the connector 801, the stability of the structure can be further improved, thereby preventing the connector 80 from becoming loose. Preferably, the preload can be a spring.
[0054] Furthermore, the auxiliary beam 40 is provided with a plurality of mounting holes arranged in an array along the first direction and on the side near the connecting assembly 80. This ensures good assembly results while also providing multiple mounting hole positions to choose from.
[0055] Furthermore, the mounting holes are angled downwards. This facilitates assembly and prevents the connecting components 80 from detaching.
[0056] Furthermore, the auxiliary beam 40 is detachably connected to the support beam 30. This facilitates easy assembly and disassembly, thereby improving assembly efficiency.
[0057] It should be noted that the detachable connection method can be a bolt connection; or it can be a snap-fit method, in which the auxiliary beam 40 is inserted onto the support beam 30, and multiple limiting holes are vertically opened on the support beam 30. This can achieve a good assembly effect.
[0058] Furthermore, the support assembly 60 includes a connecting plate 601 connected to the open end of the fixed beam 50, and a support member 602 is detachably mounted on the connecting plate 601. This allows for good assembly between components, thereby ensuring structural stability. The support member 602 is detachably mounted on the connecting plate 601, and the detachability can be achieved through snap-fit or plug-in connection.
[0059] Furthermore, the outer wall of the support member 602 is provided with a locking member for locking adjacent support members 602. It is understood that this further improves the structural stability of the support member 602.
[0060] Preferably, the locking element can be a clamp or a buckle; it can achieve the effect of limiting and fixing the support 602.
[0061] Furthermore, the inner wall of the support member 602 is provided with a cushioning pad. This provides a good cushioning effect, thereby preventing rigid contact between components. Preferably, the cushioning pad can be a rubber pad. This achieves an effect that is easy to implement and convenient to operate.
[0062] The working principle of this application is as follows:
[0063] 1. The roof steel chimney 90 support device mainly consists of three parts: a frame, columns 20, and a support ring. The frame and support ring can be welded together as a single unit, then pre-assembled with the chimney 90, and then cut in half along the centerline. Afterwards, connecting plates are welded and assembled. The support ring is clamped and fixed to the chimney 90. When the chimney 90 is installed in the boiler room, the support frame is installed in place, and the frame support ring assembly is connected and assembled using high-strength studs, with nuts tightened in place. After the columns 20 are adjusted to the installation dimensions, they are welded to the frame.
[0064] 2. Based on this device, the column 20 can be replaced with a high-load adjustable column 20 to adapt to different conditions such as flat roofs or sloping roofs.
[0065] This application also has the following beneficial effects:
[0066] 1. Solving the problem of chimney interface load-bearing capacity. Due to objective conditions, the chimney can no longer be supported by the ground. This invention minimizes the load on the boiler and chimney interface by setting up a roof support device, so that components such as energy savers and preheaters do not need additional reinforcement.
[0067] 2. Solving the problem of space occupation during the installation and fixing of steel chimneys. Steel chimneys typically occupy a certain amount of floor space when installed on the ground. This invention addresses this by incorporating a roof support device, placing the main load-bearing position of the chimney on the roof, with the lower equipment's exhaust outlet providing auxiliary positioning and fixation. This makes the chimney, based on the ground, more stable and secure. It also increases the operating space and inspection access for the boiler equipment.
[0068] 3. Solving the problem of excessive weight of steel chimneys. This problem arises because, to ensure sufficient structural strength, conventional methods for steel chimneys involve either thickening the chimney walls or installing a fixed frame. The former directly increases costs, while the latter increases the floor space required. This invention, by incorporating a roof support device, can reduce the chimney weight by one-third.
[0069] 4. If the steel chimney does not protrude much from the roof, there is no need to install steel wire ropes and locks, thus avoiding the problem of insufficient space for installing steel wire ropes and locks.
[0070] 5. Steel chimneys do not require conventional civil engineering foundations, leaving space for passageways.
[0071] 6. No load-bearing steel beams are required in the vertical direction of the boiler room or other indoor (workshop) areas.
[0072] 7. Steel chimneys can be directly installed on boilers or other flue gas equipment without considering the load-bearing capacity of the interfaces.
[0073] 8. The chimney shell has a correspondingly smaller section wall thickness, saving costs (especially for stainless steel materials).
[0074] 9. The present invention has a simple and lightweight structure, can be prefabricated in the factory, and can be directly bolted and installed on the project site.
[0075] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
