Description

Technical Field

[0001] This utility model belongs to the field of boiler steel structure technology, and specifically relates to a boiler steel structure mounting base. Background Technology

[0002] Industrial boilers, as core equipment for energy conversion, are widely used in various industrial fields such as chemical, power, and metallurgy. Their operational stability is directly related to production efficiency and operational safety. As the supporting carrier of the boiler body, the boiler steel structure must withstand the boiler's own weight, the weight of the medium, operating vibration, and complex loads such as external wind loads and earthquakes for a long time. Therefore, the structural reliability and load-bearing capacity of the mounting base are key technical points.

[0003] Existing boiler steel structure installation bases mostly adopt a single concrete pouring or simple steel structure splicing design, which has many technical limitations. First, traditional bases are mostly integrated cast-in-place structures, lacking layered bearing and load distribution design. The coordinated stress optimization between the conical support layer and the steel reinforcement skeleton is insufficient, resulting in concentrated soil pressure per unit area. Long-term use can easily lead to foundation pit settlement and affect the stability of the support. Second, the lack of precise leveling mechanisms during installation, relying on secondary leveling operations on site, not only results in long construction cycles and high labor costs, but also makes it difficult to guarantee the accuracy of the installation benchmark, thus affecting the stable operation of the boiler.

[0004] Meanwhile, existing bases have weak vibration damping performance, mostly consisting of rigid connection structures, which cannot effectively absorb the vibration and impact loads generated during boiler operation. This not only leads to structural fatigue damage and shortens the service life of the base and boiler steel structure, but also transmits vibrations to surrounding facilities, causing noise pollution or potential resonance hazards in adjacent structures. In addition, traditional bases have a single connection method, lacking multiple fixing designs including welding, bolting, and concrete curing, resulting in insufficient wind load and seismic resistance, making them unsuitable for use in complex industrial environments. Utility Model Content

[0005] In view of this, the present invention provides a boiler steel structure mounting base, in which each component is connected by welding and bolts and solidified with concrete to form multiple fixation, which improves the structure's resistance to wind loads and seismic performance. Moreover, the overall modular design facilitates later inspection and maintenance, extends the service life of the base and the boiler steel structure, and is suitable for various industrial boiler installation scenarios.

[0012] Preferably, the groove and the intermediate mounting bracket are square, and a gap is reserved between the intermediate mounting bracket and the intermediate connecting bracket. The arc-shaped elastic plate is installed in the gap.

The lower end of the L-shaped connecting column 7 is inserted into the gap between the multiple vertical reinforcing bars 3. A threaded part 8 is provided on the upper end of the L-shaped connecting column 7. The upper thread is fitted with a leveling nut 9 and a fixing nut 10, and a lower connecting plate 12 is detachably installed between the two. An intermediate connecting frame 15 is fixedly installed on the lower connecting plate 12. A groove 16 is opened on the intermediate connecting frame 15, and an intermediate mounting frame 17 is fixedly installed in the groove 16. An arc-shaped elastic plate 18 is provided between the intermediate mounting frame 17 and the intermediate connecting frame 15. An upper connecting plate 20 is provided at the upper end of the intermediate mounting frame 17, and multiple circumferentially evenly distributed connecting bolts 21 are fixedly installed on the upper connecting plate 20.

[0021] Multiple vertical reinforcing bars 3 are installed in a 'U' shape at the upper end of the conical support layer 2. A through hole 6 is provided on the top plate 5. The L-shaped connecting column 7 passes through the through hole 6 and is welded to the top plate 5. A connecting hole 13 is provided on the lower connecting plate 12. The threaded part 8 passes through the connecting hole 13. The leveling nut 9 and the fixing nut 10 are located at the upper and lower ends of the lower connecting plate 12, respectively. Two washers 11 are movably installed on the threaded part 8, distributed at the upper end of the leveling nut 9 and the lower end of the fixing nut 10. A support frame is fixedly installed at the middle position of the upper end of the lower connecting plate 12, and a middle connecting frame 15 is fixedly installed on the upper end of the support frame. Multiple reinforcing bars are provided between the lower connecting plate 12 and the middle connecting frame 15. The lower pouring layer 23 is formed by pouring concrete between the tapered support layer 2 and the lower end of the threaded part 8 on the L-shaped connecting column 7, and is buried in the foundation pit below the ground. The lower end of the middle position of the intermediate connecting frame 15 is poured with concrete between it and the lower pouring layer 23, forming an upper pouring layer 24, which is located above the ground. The groove 16 and the intermediate mounting frame 17 are square, and a gap is reserved between the intermediate mounting frame 17 and the intermediate connecting frame 15. The arc-shaped elastic plate 18 is installed in the gap. The arc-shaped elastic plate 18 is composed of three sets of superimposed arc-shaped plates, one end of which is connected and fixed to the intermediate mounting frame 17, and the other end of which is connected and fixed to the intermediate connecting frame 15.

[0022] In practical operation: The boiler steel structure installation base achieves stable support through a combination of layered load-bearing and elastic buffering design. First, the bottom load-bearing structure is formed by the foundation base 1 and the conical support layer 2. The conical support layer 2 uses an expanded diameter design to distribute the load above and evenly transfer the pressure to the foundation base 1 and the foundation pit soil. Multiple vertical steel bars 3 arranged in a "U" shape are reinforced by a horizontal connecting frame 4 to form a three-dimensional skeleton, which, together with the top plate 5, forms the intermediate load-bearing layer. The L-shaped connecting column 7 passes through the through hole 6 of the top plate 5 and is welded and fixed. Its lower end is inserted into the gap of the vertical steel bar 3 to enhance the connection strength. The conical support layer 2, the vertical steel bar 3, and the lower end of the L-shaped connecting column 7 are solidified into a whole by pouring concrete in the lower pouring layer 23, which improves the structural stability within the foundation pit. During installation, the lower connecting plate is adjusted using the leveling nut 9 of the threaded part 8 of the L-shaped connecting column 7. The boiler steel structure is leveled to ensure accurate installation reference. The lower connecting plate 12 is then locked with fixing nuts 10 to complete the positioning. The boiler steel structure is fixed by the connecting bolts 21 of the upper connecting plate 20. The load is transferred to the intermediate mounting frame 17 through the upper connecting plate 20. The three sets of superimposed arc-shaped elastic plates 18 between the intermediate mounting frame 17 and the intermediate connecting frame 15 can absorb the vibration and impact generated by the boiler operation. The arc-shaped structure deformation buffers the stress and avoids structural damage caused by rigid transmission. The support frame and reinforcing plate 14 between the intermediate connecting frame 15 and the lower connecting plate 12 strengthen the vertical bearing capacity. The upper pouring layer 24 concrete further fixes the connection between the intermediate connecting frame 15 and the lower pouring layer 23, forming a secondary stable structure above the ground. The whole structure realizes the comprehensive functions of load distribution, precise leveling, vibration buffering and stable support. Example

[0023] Based on Embodiment 1, a shock absorber 19 is provided between the intermediate mounting frame 17 and the upper connecting plate 20 for shock absorption and buffering. Multiple telescopic mechanisms 22 are provided between the intermediate connecting frame 15 and the upper connecting plate 20 to support the upper connecting plate 20 and work in conjunction with the shock absorber 19. Each telescopic mechanism 22 includes a telescopic tube fixedly installed on the intermediate connecting frame 15, a telescopic rod slidably installed on the telescopic tube, and the upper end of the telescopic rod is fixed on the upper connecting plate 20.

[0024] In practical operation: the added damping shock absorber 19 and telescopic mechanism 22 further optimize the shock absorption and support effect. After the load is transmitted to the intermediate mounting frame 17, part of the vibration and impact is directly absorbed by the damping shock absorber 19, and its damping characteristic can rapidly attenuate the vibration energy to avoid resonance. The telescopic mechanism 22 on the intermediate connecting frame 15 works in coordination with the damping shock absorber 19, and the telescopic rod inside the telescopic tube can slide flexibly along with the tiny displacement of the upper connecting plate 20, which not only provides stable vertical support for the upper connecting plate 20, but also does not hinder the buffering action of the damping shock absorber 19. When the boiler operates and generates vibration, the telescopic rod telescopically adapts along the telescopic tube, and cooperates with the arc-shaped elastic plate 18 and the damping shock absorber 19 to form a multiple buffering system, which greatly improves the impact resistance of the structure, and meanwhile ensures that the upper connecting plate 20 always maintains a stable posture, providing a more reliable mounting support foundation for the boiler steel structure.

[0025] The working principle of the utility model is as follows: the boiler steel structure mounting base realizes stable support through the design combining layered load bearing and elastic buffering. Firstly, the base base 1 and the conical support layer 2 form a bottom load-bearing structure. The conical support layer 2 disperses the upper load by using the diameter-expanding design, and uniformly transmits the pressure to the base base 1 and the foundation pit soil. A plurality of vertical rebars 3 arranged in a "loop" shape are reinforced by the transverse connecting frame 4 to form a three-dimensional framework, which cooperates with the top plate 5 to form an intermediate force-bearing layer. The L-shaped connecting column 7 passes through the through hole 6 of the top plate 5 and is fixed by welding, and its lower end is inserted into the gap between the vertical rebars 3 to enhance the connection strength. The lower ends of the conical support layer 2, the vertical rebars 3 and the L-shaped connecting column 7 are solidified into a whole through concrete pouring of the lower pouring layer 23, so as to improve the stability of the structure in the foundation pit. During installation, the leveling nut 9 on the threaded portion 8 of the L-shaped connecting column 7 is used to adjust the levelness of the lower connecting plate 12 to ensure that the mounting reference of the boiler steel structure is accurate, and then the lower connecting plate 12 is locked by the fixing nut 10 to complete positioning. The boiler steel structure is fixed by the connecting bolt 21 on the upper connecting plate 20, the load is transmitted to the intermediate mounting frame 17 through the upper connecting plate 20, and three sets of stacked arc-shaped elastic plates 18 between the intermediate mounting frame 17 and the intermediate connecting frame 15 can absorb the vibration and impact generated by the operation of the boiler, and buffer the stress through the deformation of the arc-shaped structure to avoid structural damage caused by rigid transmission. The support frame and the reinforcing plate 14 between the intermediate connecting frame 15 and the lower connecting plate 12 strengthen the vertical load bearing, and the concrete of the upper pouring layer 24 further fixes the connection between the intermediate connecting frame 15 and the lower pouring layer 23 to form a secondary stable structure above the ground. The whole structure realizes the comprehensive functions of load dispersion, precise leveling, vibration buffering and stable support.
