Description

Technical Field

[0001] This invention belongs to the field of steel structure technology, and specifically relates to a high-load-bearing steel structure support device suitable for power plants. Background Technology

[0002] High-load-bearing steel structure support devices refer to steel structure systems used to support and fix various electrical equipment, conductors, and structural components within a substation. They are a core component of the substation's steel framework. They not only provide mechanical support but also must meet multiple requirements, including electrical safety, earthquake and wind resistance, corrosion resistance, and durability.

[0003] Existing joint seismic resistance schemes rely on the initial performance of components and nodes, lacking long-term fatigue and aging resistance protection mechanisms. Under the long-term complex service environment of power plants, problems such as component fatigue, damping aging, and node loosening are inevitable, directly leading to a continuous decline in the overall buffer and seismic resistance capacity of the structure, making later operation and maintenance difficult and posing structural safety hazards. It is necessary to design a high-load-bearing steel structure support device suitable for power plants to solve the above problems. Summary of the Invention

[0009] Preferably, the reinforcing support base is square in shape, and the position of the reinforcing outer frame corresponds to the position of the wing plates of the longitudinal I-beam steel frame and the transverse I-beam steel frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

By setting up reinforced support seats at the intersection of longitudinal and transverse I-shaped steel frames, the reinforced outer frame of the reinforced support seat is fixedly connected to the steel frame wing plate and works in conjunction with the inner reinforced frame on the inside.

By rotating the anchor bolt body through the rotating seat, the reinforcing seat can be moved, so that the reinforcing support plate presses tightly against the hole wall under the guidance of the top seat of the anchor bolt, forming a self-locking effect. This effectively solves the problem of traditional anchor bolts being prone to loosening and reducing anchoring force under long-term vibration environment, significantly enhances the connection strength and durability between the steel structure base and the concrete base, and ensures the long-term structural safety of the device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figures 1 to 9 The present invention provides a technical solution: a high-load-bearing steel structure support device suitable for power plants, comprising: Concrete base 1, as the basic load-bearing structure of the entire support device, is used to evenly transfer the upper load to the foundation and ensure the overall installation stability. The steel structure base 2 includes a longitudinal I-beam steel frame 21 and a transverse I-beam steel frame 22. The longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22 are arranged perpendicularly to each other to form a grid-like load-bearing main body, which meets the requirements of large span and high load-bearing installation of power station equipment. A reinforcing support 3 is fixedly installed at the intersection of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22 to strengthen the rigidity of the intersection node, prevent node deformation and cracking under stress, and improve the overall torsional and compressive resistance. Top reinforcement brackets are fixedly installed on the upper wing plates of both the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22. The reinforcing plate 23 is used to expand the upper bearing area, disperse the concentrated load, and prevent the steel frame wing plate from being deformed by local pressure. The concrete base 1 is pre-embedded and fixed with limit anchor bolts 24 to achieve rigid anchoring between the steel structure base and the concrete base, preventing vertical loosening and horizontal slippage. At the same time, the surface of the concrete base 1 is equipped with an installation component 5 corresponding to the position of the steel structure base 2, which is used to limit and fix the end of the steel frame, further improving the overall installation stability. The longitudinal I-shaped steel frame 21 and the transverse I-shaped steel frame 22 are fixedly installed on the upper surface of the concrete base 1 through the limit anchor bolts 24 and the installation component 5. The vibration damping buffer seat 4 is used to absorb vibrations from equipment operation, earthquakes, and wind loads, preventing vibrations from being directly transmitted to the steel frame and foundation, and mitigating the problem of seismic performance degradation. The vibration damping buffer seat 4 includes a main damping seat 41 and a buffer mounting seat 42. The lower side of the main damping seat 41 is equipped with a detachable mounting mechanism 6 for quick assembly and disassembly of the vibration damping buffer seat, facilitating future maintenance and replacement. The main damping seat 41 is fixedly connected to the top reinforcing plate 23 through the mounting mechanism 6. The buffer mounting seat 42 is vertically slidably installed on the upper inner side of the main damping seat 41. The top of the buffer mounting seat 42 has a reserved equipment installation position for directly fixing various heavy-duty electrical equipment of the power station. The internal cavity of the main damping seat 41 is equipped with a viscous damper 45 and a buffer. A spring 46 and a viscous damper are used to dissipate high-frequency vibration energy. A buffer spring is used to provide elastic restoring force to achieve vertical buffering of the foundation. The buffer spring 46 is coaxially sleeved on the outside of the viscous damper 45, and a friction damping block 47 is fixedly installed at the end of the buffer spring 46 near the inner wall of the damping main seat 41 to further dissipate vibration energy with sliding friction. An auxiliary damping spring 49 is fixedly installed on the inner wall of the damping main seat 41 to provide auxiliary buffer damping and improve the overall damping durability. A synchronous pressure plate 482 is fixedly installed at the end of the auxiliary damping spring 49 away from the inner wall. A friction damping slider 48 is fixedly installed on the side of the synchronous pressure plate 482 away from the auxiliary damping spring 49. The friction damping block 47 The end furthest from the buffer spring 46 is slidably connected to the friction damping slider 48, achieving multi-stage energy dissipation through inclined sliding friction, avoiding fatigue failure of a single damping structure after long-term use; a buffer protrusion 44 is integrally provided in the middle of the lower end of the buffer mounting base 42, and the bottom end of the buffer protrusion 44 is fixedly connected to the top end of the viscous damper 45 and the buffer spring 46, realizing synchronous transmission of vertical force, ensuring that the vibration load is evenly applied to the damping component, and avoiding damping failure caused by uneven local force; a limit plate 481 is fixedly installed at the bottom end of the friction damping slider 48 to limit the sliding stroke of the friction damping slider, prevent excessive sliding and slippage, and ensure the continuous and stable action of friction damping. The inner side wall of the damping main seat 41 corresponds to the synchronous pressure At position 482, a vertical limiting guide post 483 is fixedly installed. The synchronous pressure plate 482 is sleeved on the outside of the limiting guide post 483 and is vertically slidably connected to the limiting guide post 483 to ensure that the friction damping slider 48 slides smoothly without deviation, avoiding jamming or misalignment that would affect the damping effect. The contact surfaces of the friction damping pressure block 47 and the friction damping slider 48 are both set as mutually compatible inclined surfaces. The two slide against each other through the inclined surfaces, and the friction energy is dissipated by the pressure of the inclined surfaces, thereby improving the energy dissipation efficiency. The limiting protrusion 481 is located below the lowest end of the inclined surface of the friction damping slider 48 to limit the sliding stroke of the friction damping slider 48, prevent slippage, and at the same time ensure that the friction contact surfaces are always in contact, maintaining a stable damping effect.

[0022] The shock absorber seat 4 achieves multi-stage coordinated energy dissipation through frictional damping, elastic buffering, and viscous damping. Primary buffer: The basic elastic recovery and vibration absorption are achieved by using the buffer spring 46.

[0023] Secondary damping: Vibration energy is efficiently dissipated through the inclined sliding friction between the friction damping block 47 and the friction damping slider (48).

[0024] Level 3 assistance: Combined with the reverse buffering effect of the auxiliary damping spring 49, it forms a multi-dimensional energy absorption mechanism; As can be seen from the above description, the present invention has the following beneficial effects: it avoids the problem of elastic fatigue and buffer capacity decay caused by long-term use of a single shock absorption structure, so that the device can maintain excellent anti-seismic buffer performance throughout its entire life cycle, and is particularly suitable for complex environments in power plants with extremely high requirements for structural safety.

[0025] Further reading is available. Figure 1-7 The reinforced support 3 includes a reinforced outer frame 31. A reinforced fixing seat 33 is fixedly installed on the side of the reinforced outer frame 31 near the steel frame. The reinforced fixing seat 33 is fitted and fixed to the outer side of the web and flange of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22, achieving multi-point fitting and fixing to enhance the connection strength. An inner reinforcing frame 32 is fixedly installed on the inner side of the reinforced outer frame 31 to improve the overall rigidity. The double reinforcement structure further enhances the load-bearing capacity of the nodes and prevents long-term heavy load deformation. The reinforced support 3 has a square frame structure and is compatible with the cross-shaped steel frames. The node shape achieves full-coverage reinforcement. The installation position of the reinforced outer frame 31 corresponds one-to-one with the wing plate positions of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22, precisely fitting the stress-bearing parts and enhancing local rigidity. Reinforced connection holes 34 are opened at both ends of the reinforced outer frame 31. The reinforced outer frame 31 is fixedly connected to the wing plates of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22 through the reinforced connection holes 34 and fastening screws, achieving double reinforcement, further improving the node's resistance to deformation and cracking, and extending the service life of the steel frame.

[0026] By adopting the above technical solution, a reinforced support 3 is installed at the intersection of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22. The reinforced outer frame 31 of the reinforced support 3 is fixedly connected to the steel frame flange and, together with the inner reinforcing frame 32, effectively solves the technical problems of easy deformation and poor torsional resistance at the frame intersection nodes in the high load-bearing structure of the power station. It significantly improves the load-bearing capacity and overall stiffness of the connection, ensures the stability of the structure under long-term heavy loads and complex working conditions, and avoids node cracking or damage.

[0027] Further reading is available. Figure 1-4The installation mechanism 6 includes a fixed insert plate 63 and a limiting slot 61. The fixed insert plate 63 is fixedly installed on the upper surface of the top reinforcing plate 23, and the limiting slot 61 is correspondingly opened on the lower surface of the shock-absorbing main seat 41, so as to realize the quick alignment and installation of the shock-absorbing buffer seat and improve the installation efficiency. One end of the limiting slot 61 has a horizontally opened installation groove 62, and a fixing block 64 is slidably installed inside the installation groove 62. A fixing screw 65 is horizontally screwed into one side wall of the shock-absorbing main seat 41, and one end of the fixing screw 65 extends into the installation groove 62 and is rotatably connected to the fixing block 64. The locking mechanism is achieved by rotating the screw to push the pressure block, which is easy to operate. The fixed insert plate 63 is matched and engaged inside the mounting slide 62. The cross-sectional shape of the fixed insert plate 63 is designed as a dovetail structure. The dovetail structure has anti-loosening properties to prevent the shock-absorbing buffer seat from shifting due to long-term vibration. The end of the limiting slot 61 away from the mounting slide 62 and the end of the fixed pressure block 64 close to the fixed insert plate 63 are respectively pressed and attached to the two inclined surfaces of the dovetail fixed insert plate 63 to achieve anti-loosening locking and fixation, further ensuring the stable installation of the shock-absorbing component and not affecting the shock absorption effect.

[0028] Example 2: Please see Figures 1 to 3As shown, based on Embodiment 1, the present invention provides a technical solution: the limiting anchor bolt 24 includes an anchor bolt hole 241 and an anchor bolt body 242. The anchor bolt hole 241 is pre-reserved inside the concrete base 1 to provide a reserved position for anchor bolt installation and ensure anchoring accuracy. A reinforcing seat 244 is installed inside the anchor bolt hole 241. The reinforcing seat 244 is connected to the anchor bolt body 242 by threaded engagement, and internal locking is achieved through threaded transmission to improve anchoring force. Several reinforcing support plates 245 are evenly fixedly installed on the outer side of the reinforcing seat 244 to expand the contact with the inner wall of the anchor bolt hole. To enhance contact area and pull-out resistance, the anchor bolt body 242 is vertically installed inside the anchor bolt hole 241. An anchor bolt top seat 243 is fixedly installed on the outer side of the top of the anchor bolt body 242. The bottom of the anchor bolt top seat 243 has a guide slope that matches the reinforcing support plate 245, guiding the reinforcing support plate outwards for self-locking fastening. A connecting screw head 247 is fixedly installed at the bottom of the anchor bolt body 242 for quick docking and locking with the steel frame. A rotating seat 246 is provided at the top of the anchor bolt body 242, with its bottom fixedly connected to the anchor bolt body 242 for easy... On-site rotation operation completes the anchoring and locking; the cross-sectional shape of the anchor bolt hole 241 is set as a square structure, and the shape of the reinforcing seat 244 is adapted to the square anchor bolt hole 241 to prevent the reinforcing seat 244 from rotating circumferentially, avoid free rotation and slippage during rotational anchoring, and ensure that the locking is in place; the shape of the anchor bolt top seat 243 is set as a frustum structure, and the reinforcing support plate 245 slides along the guide slope of the anchor bolt top seat 243 and then tilts outward, pressing tightly against the inner wall of the anchor bolt hole 241 to achieve locking and fixation, effectively preventing the anchor bolt from loosening due to long-term vibration and ensuring the long-term stability of the foundation connection; 5 packages of installation components. The system includes a limiting bracket 51, with an installation hole 52 at one end near the steel frame. The end of the transverse I-shaped steel frame 22 engages and embeds into the installation hole 52, enabling rapid positioning of the steel frame end, limiting lateral displacement, and facilitating subsequent fixing. Fixed anchor bolts 53 are provided at the four corners of the limiting bracket 51. The limiting bracket 51 is fixedly installed on the concrete base 1 by the fixed anchor bolts 53, and the structure of the fixed anchor bolts 53 is completely consistent with the structure of the limiting anchor bolts 24, unifying the anchoring structure, ensuring consistent overall connection stability, and simplifying the installation and maintenance process.

[0029] The above technical solution employs a structure where the limiting anchor bolt 24 has a square anchor bolt hole 241 and a threaded drive reinforcing seat 244. By rotating the anchor bolt body 242 through the rotating seat 246, the reinforcing seat 244 can be moved, causing the reinforcing support plate 245 to press tightly against the hole wall under the guidance of the anchor bolt top seat 243, forming a self-locking effect. This design effectively solves the problem of traditional anchor bolts being prone to loosening and reducing anchoring force under long-term vibration, significantly enhancing the connection strength and durability between the steel structure base and the concrete base, and ensuring the long-term structural safety of the device.

[0030] The working principle and usage process of this invention are as follows: First, the pre-embedding and fixing of the limiting anchor bolt 24 and the fixing anchor bolt 53 on the concrete base 1 are completed: a square anchor bolt hole 241 is reserved in advance during the concrete base 1 pouring stage. The assembled reinforcing seat 244 and the anchor bolt body 242 are inserted into the anchor bolt hole 241 as a whole. The anchor bolt body 242 is rotated by rotating seat 246. The reinforcing seat 244 is driven to move upward along the anchor bolt body 242 by thread transmission, so that the reinforcing support plate 245 gradually approaches the frustum-shaped anchor bolt top seat 243. Under the action of the guide slope of the anchor bolt top seat 243, the reinforcing support plate 245 is evenly raised outward and tightly pressed against the inner wall of the square anchor bolt hole 241, which greatly improves the biting force between the anchor bolt and the concrete base and avoids the anchor bolt loosening and displacement problems after long-term use. Then, the anchor bolt is rigidly connected to the longitudinal I-shaped steel frame 21, the transverse I-shaped steel frame 22 and the limiting seat 51 by connecting screw head 247 and locking nut.

[0031] The steel structure base 2 is then assembled: the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22 are spliced ​​together in a vertical orientation, and a reinforcing support seat 3 is installed at all splicing nodes; during installation, the reinforcing fixing seat 33 is tightly fitted and fixed to the outer side of the web of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22, and then the reinforcing outer frame 31 is locked and fixed to the steel frame wing plate through the reinforcing connection hole 34 and the fastening screw. With the inner reinforcing frame 32 on the inner side, the torsional and compressive stiffness of the cross node is greatly improved, solving the problem of weak stress and easy deformation of traditional steel frame nodes, and avoiding node cracking and stiffness reduction under long-term heavy load.

[0032] Next, the mounting holes 52 at the ends of the limiting bracket 51 are fitted onto both ends of the transverse I-beam steel frame 22. The limiting bracket 51 is then firmly fixed to the concrete base 1 using the fixing anchor bolts 53. Simultaneously, the limiting anchor bolts 24 work together to complete the overall positioning and locking of the longitudinal I-beam steel frame 21 and the transverse I-beam steel frame 22, achieving an integrated connection between the steel structure base and the concrete base, preventing horizontal slippage or vertical loosening. Afterwards, the top reinforcing plate 23 is fixedly welded to the upper wing plate surface of the transverse I-beam steel frame 22 and the longitudinal I-beam steel frame 21, further increasing the load-bearing area and overall rigidity of the top of the steel frame, and dispersing the concentrated load transmitted by the upper equipment.

[0033] Finally, complete the installation of the shock absorber base 4: Align the limiting slot 61 at the bottom of the shock absorber base 41 with the dovetail-shaped fixing plate 63 on the top reinforcing plate 23 and insert it. Rotate the fixing screw 65 to push the fixing block 64 in the installation slide 62 towards the fixing plate 63 until the fixing block 64 and the end of the limiting slot 61 tightly press the fixing plate 63, thus realizing the quick disassembly and assembly and firm fixation of the shock absorber base, making subsequent operation and maintenance and replacement more convenient. Fix various electrical equipment and heavy-duty components of the power station to the installation position on the top of the shock absorber base 42 with bolts, and it can be put into use.

[0034] During long-term use, when subjected to external forces such as equipment operation vibration, seismic load, and wind vibration, the vibration load is transmitted from top to bottom to the buffer mounting base 42. Through the buffer protrusion 44 at the bottom of the buffer mounting base 42, the viscous damper 45 and the buffer spring 46 are simultaneously compressed to achieve the first-level vertical buffering and vibration reduction. While the buffer spring 46 is compressed, it drives the friction damping block 47 at its end to slide along the inclined surface of the friction damping slider 48. The vibration energy is consumed through the sliding friction between the two, achieving the second-level friction damping energy dissipation. After being subjected to force, the friction damping slider 48 slides smoothly along the limiting guide post 483, driving the synchronous pressure plate 482 to compress the auxiliary damping spring 49. The elastic deformation of the auxiliary damping spring 49 achieves the third-level auxiliary buffering. The multi-level damping works synergistically to effectively alleviate the problems of elastic fatigue and damping attenuation after long-term use of traditional single vibration reduction structures, continuously ensuring the stability of the buffering and seismic performance, significantly extending the service life of the device, and improving the safety and stability of the operation of heavy-load equipment in the power station.
