Description

Technical Field

[0001] This utility model relates to the field of power plant boiler technology, specifically a steel structure support frame for a vertical power plant boiler. Background Technology

[0002] A steel structure is an integral structure formed by connecting steel components through certain nodes. The nodes must possess sufficient strength, stiffness, and ductility to ensure the correct positioning of the connected components, meet load-bearing and usage requirements, and guarantee the structural integrity during use. In the manufacturing and operation of boilers, the boiler steel frame is a major supporting component and plays a crucial role. Currently, boiler steel frames generally adopt a box-type structure, consisting of columns, beams, and connecting components such as bolts.

[0003] However, due to their vertical design, typical vertical power plant boilers are quite long and require hoisting and suspension onto a support frame for installation and fixation. Since the support frame is the sole support component for the vertical boiler, and because the steel structure of the support frame is entirely steel-connected, it is prone to vibration during strong winds. Furthermore, the suspended design of the vertical boiler causes the boiler body itself to vibrate easily. This vibration between the two can easily lead to resonance and damage to the support structure, causing serious safety issues. To address these problems, the purpose of this invention is to provide a steel structure support frame for vertical power plant boilers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a steel structure support frame for a vertical power plant boiler. This solves the problem that, due to the vertical design of typical vertical power plant boilers, the boiler itself is quite long and requires hoisting and suspending on the support frame for installation and fixation. Since the support frame is the sole support component for the vertical boiler, and because the entire steel structure support frame is made of steel connections, it is prone to vibration in strong winds. Furthermore, the suspended design of the vertical boiler also causes vibration in the boiler body. This vibration between the two components can easily lead to resonance and damage to the support structure, causing serious safety issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical power plant boiler steel structure support frame, comprising a vibration-damping steel structure frame. The vibration-damping steel structure frame includes a main support frame, top plate beams / columns, boiler connectors, and vibration-damping components. The main support frame supports the boiler. The top plate beams / columns are fixedly connected to the top of the main support frame. A slide rail is installed within the top plate beams / columns, and the boiler connectors are slidably connected within the slide rails. The boiler connectors are used to connect the boiler. Two sets of vibration-damping components are symmetrically installed. Each vibration-damping component includes a hydraulic damper, a spring, and a rubber damping ring. The spring is mounted on the telescopic rod of the hydraulic damper. One end of the hydraulic damper is mounted on the top plate beam / column, and the rubber damping ring is mounted on the other end of the hydraulic damper, abutting against the boiler connector. Preferably, two sets of top plate beams / columns are symmetrically arranged, and fixing through holes are provided in both the top plate beams / columns and the slide rails.

[0006] Preferably, the boiler connector includes a sliding block and a sliding groove. Two sets of sliding blocks are provided, and the sliding groove is opened inside the sliding block and is slidably connected to the slide rail.

[0007] Preferably, the boiler connector further includes a supporting arc block and a boiler connecting plate. The supporting arc block is fixedly connected to the top of the sliding block, and two sets of the sliding blocks are fixedly connected to the top of the boiler connecting plate. The rubber damping ring abuts against the supporting arc block.

[0008] Preferably, the vibration damping component further includes a support plate, which is installed inside the top beam column. The upper and lower ends of the support plate are provided with fixing bolts, which are fixedly connected to the fixing through holes.

[0009] Preferably, crossbeams are fixedly connected between the main support frames, and the crossbeams are used to support the main support frames. Compared with the prior art, the beneficial effects of this utility model are: this vertical power plant boiler steel structure support frame, by setting anti-vibration components, can block and buffer the vibration between the main support frame and the boiler to a certain extent, preventing resonance between the two, and the buffering and vibration reduction effect can be adjusted by the installation position of the support plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. The embodiments of this application provide a steel structure support frame for a vertical power plant boiler, which solves the problem that, due to the vertical design of general vertical power plant boilers, the boiler body is long and needs to be hoisted and suspended on the support frame for installation and fixation. Since the support frame is the only support component of the vertical boiler, and the steel structure support frame is made of steel connections, it is prone to overall vibration in windy weather. Due to the suspended design of the vertical boiler, the boiler body is also prone to vibration. The vibration between the two can easily cause resonance and damage to the support structure, resulting in serious safety problems.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please see Figure 1-5 This utility model provides a technical solution:

[0019] Example 1

[0020] The system includes a vibration-damping steel frame 1, within which are a main support frame 11, a top plate beam and column 12, a boiler connector 13, and vibration-damping components 15. The main support frame 11 supports the boiler. The top plate beam and column 12 are fixedly connected to the top of the main support frame 11. A slide rail 121 is installed inside the top plate beam and column 12. The boiler connector 13 is slidably connected inside the slide rail 121 and is used to connect the boiler. Two sets of vibration-damping components 15 are symmetrically installed. Each vibration-damping component 15 includes a hydraulic damper 152, a spring 153, and a rubber damping ring 154. The spring 153 is installed on the telescopic rod of the hydraulic damper 152. One end of the hydraulic damper 152 is installed on the top plate beam and column 12, and the rubber damping ring 154 is installed on the other end of the hydraulic damper 152. The rubber damping ring 154 abuts against the boiler connector 13.

[0021] During use, the hydraulic dampers 152 at both ends press against the boiler connector 13 in the middle through the telescopic rod, spring 153, and rubber damping ring 154. When vibration occurs, the vibration of the boiler is transmitted to the boiler connector 13. The boiler connector 13 is slidably connected to the top beam and column 12 and transmitted to the anti-vibration steel structure frame 1 after the vibration is reduced by the anti-vibration component 15. This causes the vibration of the two to be out of sync, reduces the vibration effect, and eliminates the generation of resonance.

[0022] The boiler connector 13 includes a sliding block 131 and a slide groove 132. The sliding block 131 is also provided with two sets. The slide groove 132 is opened in the sliding block 131 and is slidably connected to the slide rail 121. The boiler connector 13 also includes a supporting arc block 133 and a boiler connecting plate 134. The supporting arc block 133 is fixedly connected to the top of the sliding block 131. The two sets of sliding blocks 131 are fixedly connected to the top of the boiler connecting plate 134. The rubber damping ring 154 abuts against the supporting arc block 133.

[0023] The rubber damping ring 154 and the spring 153 both serve to keep the hydraulic damper 152 constantly resisting the sliding block 131.

[0024] Example 2 is based on Example 1;

[0025] The top plate beams and columns 12 are provided in two sets symmetrically arranged on the left and right sides, and both the top plate beams and columns 12 and the slide rails 121 are provided with fixing through holes 122.

[0026] The vibration damping component 15 also includes a support plate 151, which is disposed within the top beam column 12. Fixing bolts 155 are provided at both the upper and lower ends of the support plate 151, and are fixedly connected to the fixing through holes 122. By installing the support plate 151 in the fixing through holes 122 at different distances, the distance between the hydraulic damper 152 and the sliding block 131 is different, resulting in different potential energy effects of the rubber damping ring 154 and the spring 153. A crossbeam 14 is fixedly connected between the main support frames 11, and the crossbeam 14 supports the main support frames 11. The above describes and illustrates the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
