Description

Technical Field

[0001] This utility model belongs to the technical field of boiler steel frame technology, and specifically relates to a steel frame for the installation of multiple boilers in a coordinated manner. Background Technology

[0002] During boiler installation and operation, steel structure supports serve as critical supporting components. Their adaptability, stability, and vibration damping performance directly impact boiler installation efficiency and long-term operational safety. This is especially true when installing multiple boilers, where the balance of support for each boiler and the overall layout must be considered simultaneously. This places higher demands on the precision of support spacing adjustment and adaptability to different boiler specifications. If the support spacing cannot be flexibly adjusted, uneven stress on the boilers can easily occur, increasing the difficulty of installation and commissioning and potentially causing steel frame deformation due to localized stress concentration. Furthermore, the combined vibrations from multiple boilers operating simultaneously, without effective vibration damping design, can exacerbate structural damage after being transmitted to the supports, seriously threatening the overall system's operational stability. Therefore, optimizing related support structures has always been a key focus in the industry.

[0003] A search revealed that the existing technology (publication number CN213334326U) describes a steel structure for linking multiple boiler steel frames, including columns, fixing blocks, workbenches, and supporting base plates. Each column has a supporting base plate at its bottom end, and one end of the outer wall of each column has an anti-slip structure. This anti-slip structure includes an inner column, a supporting block, a sealing block, a handle, a rubber sleeve, and a rubber protrusion. The handles are all located on the outer surface of the columns. Guardrails are installed at both ends of the top of the second crossbeam, and a reinforcement structure is installed at the bottom end of the second crossbeam. However, this existing technology does not allow for distance adjustment on the steel frame, making it difficult to ensure uniform stress distribution across the supporting steel frames. This can cause uneven stress on individual steel frame columns, potentially leading to structural damage over time. Furthermore, it is not adapted to boilers of different heights and does not mitigate boiler vibration damage to the steel frame through shock absorption, making it inflexible in meeting the installation needs of various boiler types and failing to guarantee operational safety.

[0004] Further research revealed that the prior art (publication number CN223201425U) describes a steel structure support for boilers. The key technical features include a horizontal gas-fired hot water boiler body, a steel structure support frame fixedly connected to the bottom of the boiler body, a lifting ring at the top of the boiler body, and an auxiliary mechanism at the top of the steel structure support frame. This auxiliary mechanism includes a load-bearing component and a control component. The load-bearing component is located at the top of the steel structure support frame, and the control component is located outside the load-bearing component. This prior art does not mitigate boiler vibration damage to the steel frame through shock absorption, cannot flexibly meet the installation needs of various types of boilers, and is difficult to guarantee operational safety. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a steel frame for the installation of multiple boilers in a linkage project. Through the flat pushing mechanism and the shock absorption mechanism, it ensures that each supporting steel frame is evenly stressed, while effectively preventing vibration from being directly transmitted to the supporting steel frame, reducing vibration damage to the supporting steel frame, and ensuring the overall structural stability and operational safety.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A steel frame for installing multiple boilers in a coordinated manner includes a mounting base, a supporting steel frame, a shock-absorbing mechanism, boilers, and a horizontal pushing mechanism. The mounting base is provided with a slide rail and several sets of threaded holes on both sides of the slide rail. The supporting steel frame is provided with several sets of supporting steel frames. The supporting steel frame slides and adjusts on the mounting base via the slide rail and is fixedly installed on the mounting base via bolts and threaded holes. The boilers are installed inside the supporting steel frame, the shock-absorbing mechanism is installed on the supporting steel frame, and the horizontal pushing mechanism is installed between the several sets of supporting steel frames.

[0008] The boilers are provided in several ways and are interconnected by a steam header. The fixed end of the steam header is installed on the top of the push mechanism and the sliding end of the steam header is fixedly connected to the boiler outlet.

[0009] The supporting steel frame includes steel frame column I, reinforcing rib I, welded base plate, mounting base plate, steel frame beam I, reinforcing rib II, steel frame beam II, and a pusher frame. The mounting base plate has welded base plates at all four ends, and the boiler is mounted on the mounting base plate. Steel frame column I is welded to the top of the welded base plate. Reinforcing rib I is welded to the connection between steel frame column I and the bottom of the welded base plate. A sliding block is provided at the bottom of the welded base plate, and the sliding block is slidably connected to a slide rail. Steel frame beam I is connected to the top two ends of steel frame column I via bolts and nuts. Steel frame beam II is connected to the top two sides of steel frame column I via bolts and nuts. Reinforcing rib II is installed at the bottom of steel frame beam I via bolts and nuts. A connecting frame is provided at the bottom of steel frame beam II. A pusher frame is welded to the corresponding end of steel frame column I and the pusher mechanism.

[0010] The shock absorption mechanism includes a connecting plate I, a lead screw, a sliding rod, a sliding seat, a mounting seat, a hydraulic cylinder I, a connecting plate II, a motor I, a sliding shell, a spring-damped shock absorber, and a bellows-style protective cover. The connecting plate II is installed on the connecting frame, and the mounting seat is installed on the bottom of both sides of the supporting steel frame. The mounting seat is fixedly connected to the steel frame column I by bolts and nuts. The connecting plate I is installed on the top of both sides of the supporting steel frame and welded to the steel frame column I. A sliding rod is provided between the connecting plate I and the mounting seat. A lead screw is rotatably installed between the connecting plate II and the mounting seat. The top of the lead screw passes through the connecting plate II and is provided with a synchronous pulley. The two sets of synchronous pulleys are connected by a synchronous belt. The motor I is installed on the connecting plate II, and the output end of the motor I is fixedly connected to a set of lead screws. The sliding seat is slidably connected to the sliding rod and threadedly connected to the lead screw. Several sets of hydraulic cylinders I are installed on the mounting seat and the sliding seat. The top end of the hydraulic cylinder I is fixedly connected to the sliding shell. A spring-damped shock absorber is installed inside the sliding shell. One end of the spring-damped shock absorber is provided with a top block, and the top block is slidably connected to the sliding shell.

[0011] The lead screw and sliding rod are each fitted with a bellows-style protective cover, which is located on both sides of the sliding seat. The top of the connecting plate II is equipped with a protective cover to protect the motor I, belt and pulley.

[0012] The pushing mechanism includes steel frame columns II and a fixed seat; there are two sets of steel frame columns II and they are installed on the mounting base. The steel frame columns II are located between multiple sets of supporting steel frames. A fixed seat is welded between the two sets of steel frame columns II. Hydraulic cylinders II are provided on both sides of the fixed seat. The top end of the hydraulic cylinders II is fixedly connected to the pushing frame. A fixed plate is provided on the top of the two sets of steel frame columns II. The fixed plate is fixedly connected to the fixed end of the steam header pipe.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1) During installation, the hydraulic cylinders II on both sides of the fixed base extend and retract, and the top end pushes the flat push frame, which drives the sliding block at the bottom of the support steel frame to slide along the slide rail of the mounting base. This adjusts the spacing of multiple sets of support steel frames, ensuring that the spacing of multiple sets of support steel frames is adjusted evenly. This prevents the support steel frames from bearing additional stress due to uneven force distribution, protects the support steel frame structure, reduces the risk of damage, and provides a stable installation foundation for the boiler, ensuring the stability and safety of subsequent boiler installation.

[0015] 2) Motor I drives a set of lead screws to rotate, which in turn drives another set of lead screws to rotate synchronously via a synchronous pulley and belt. When the lead screws rotate, the sliding seat slides up and down along the sliding rod. Hydraulic cylinder I pushes out, making the top block fit against the outer wall of the boiler. When the boiler vibrates during operation, the top block transmits the vibration force to the spring damping shock absorber. At the same time, the top block slides inside the sliding shell, preventing the vibration from being directly transmitted to the supporting steel frame. The lead screw driven by motor I allows the sliding seat to rise and fall smoothly along the sliding rod, and its position can be flexibly adjusted to adapt to boilers of different heights. When the boiler vibrates during operation, the top block transmits the vibration force to the spring damping shock absorber. The vibration is buffered by the extension and contraction of the spring and the damping effect. The top block can slide inside the sliding shell, effectively preventing the vibration from being directly transmitted to the supporting steel frame, reducing the damage to the supporting steel frame caused by vibration, and ensuring the overall structural stability and operational safety.

[0024] To facilitate understanding by those skilled in the art, the following is in conjunction with the appendix. Figure 1-7 The technical solution of this utility model will be further described in detail below.

[0025] A multi-boiler linkage installation steel frame includes an installation base 1, a support steel frame 2, a shock absorption mechanism 3, a boiler 4, and a horizontal pushing mechanism 5. The installation base 1 is provided with a slide rail 101, and both sides of the slide rail 101 are provided with several sets of threaded holes. The support steel frame 2 is provided with several sets. The support steel frame 2 slides and adjusts on the installation base 1 through the slide rail 101 and is fixedly installed on the installation base 1 by bolts and threaded holes. The boiler 4 is installed inside the support steel frame 2, the shock absorption mechanism 3 is installed on the support steel frame 2, and the horizontal pushing mechanism 5 is installed between several sets of support steel frames 2.

[0026] The boiler 4 is provided in several ways, and the boilers 4 are interconnected by a steam header 41. The fixed end of the steam header 41 is installed on the top of the push mechanism 5, and the sliding end of the steam header 41 is fixedly connected to the steam outlet of the boiler 4.

[0027] The supporting steel frame 2 includes steel frame columns I 21, reinforcing ribs I 2101, a welded base plate 2102, an installation base plate 22, steel frame beams I 24, reinforcing ribs II 25, steel frame beams II 26, and a pusher frame 28. The installation base plate 22 has welded base plates 2102 welded to its four ends. The boiler 4 is installed on the installation base plate 22. Steel frame columns I 21 are welded to the top of the welded base plate 2102, and reinforcing ribs I 2101 are welded to the connection between the steel frame columns I 21 and the bottom of the welded base plate 2102. The bottom of the welded base plate 2102 is provided with a sliding block 23, which is slidably connected to the slide rail 101. The top two ends of the steel frame column I 21 are connected to the steel frame beam I 24 by bolts and nuts. The top two sides of the steel frame column I 21 are connected to the steel frame beam II 26 by bolts and nuts. The reinforcing rib II 25 is installed at the bottom of the steel frame beam I 24 by bolts and nuts. The bottom of the steel frame beam II 26 is provided with a connecting frame 27. The steel frame column I 21 and the corresponding end of the flat pushing mechanism are welded with a flat pushing frame 28.

[0028] As described above, during installation, the sliding block 23 at the bottom of the support steel frame 2 is first pushed along the slide rail 101 of the mounting base 1 by the flat pushing mechanism 5 to adjust the spacing of multiple sets of support steel frames 2, ensuring that the spacing of multiple sets of support steel frames 2 is adjusted evenly, and avoiding the support steel frames 2 from bearing additional stress on individual steel frame columns I21 due to uneven force. The boiler 4 is installed in the support steel frame 2. When adjusting the spacing, the sliding end of the steam header 41 moves synchronously with the boiler 4, and the fixed end remains stable at the top of the flat pushing mechanism 5. After adjustment, it is fixed with bolts to the threaded holes on both sides of the slide rail 101. During operation, the shock absorption mechanism 3 alleviates the impact of the boiler 4 vibration on the support steel frame 2, ensuring the coordinated operation of multiple boilers.

[0029] The shock absorption mechanism 3 includes a connecting plate I 31, a lead screw 32, a sliding rod 33, a sliding seat 34, a mounting seat 35, a hydraulic cylinder I 36, a connecting plate II 37, a motor I 38, a sliding shell 39, a spring-damped shock absorber 311, and a bellows-type protective cover 7. The connecting plate II 37 is mounted on the connecting frame 27, and the mounting seat 35 is mounted on the bottom ends of both sides of the supporting steel frame 2. The mounting seat 35 is fixedly connected to the steel frame column I 21 by bolts and nuts. The connecting plate I 31 is mounted on the top ends of both sides of the supporting steel frame 2 and is welded to the steel frame column I 21. A sliding rod 33 is provided between the connecting plate I 31 and the mounting seat 35. The connecting plate II 37 and the mounting seat 35 are connected by a sliding rod 33. A lead screw 32 is rotatably mounted on the connecting plate II 37. The top end of the lead screw 32 passes through the connecting plate II 37 and is equipped with a synchronous pulley. The two sets of synchronous pulleys are connected by a synchronous belt. The motor I 38 is mounted on the connecting plate II 37. The output end of the motor I 38 is fixedly connected to a set of lead screws 32. The sliding seat 34 is slidably connected to the sliding rod 33 and threadedly connected to the lead screw. Several sets of hydraulic cylinders I 36 are mounted on the mounting base 35 and the sliding seat 34. The top end of the hydraulic cylinder I 36 is fixedly connected to the sliding shell 39. A spring damping shock absorber 311 is installed inside the sliding shell 39. One end of the spring damping shock absorber 311 is provided with a top block 310. The top block 310 is slidably connected to the sliding shell 39.

[0030] The lead screw 32 and the sliding rod 33 are both fitted with bellows-type protective covers 7. The bellows-type protective covers 7 are located on both sides of the sliding seat 34. The top of the connecting plate II 37 is provided with a protective cover 6, which is used to protect the motor I 38, the belt and the pulley.

[0031] A set of hydraulic cylinders I36 on a set of mounting base 35 and sliding base 34 are synchronously extended and retracted using a synchronous hydraulic method. That is, the hydraulic cylinders I36 on the set of mounting base 35 and sliding base 34 are connected in series. When the hydraulic pump starts, it outputs pressure oil, which enters the solenoid directional valve after being stabilized. When the directional valve is energized in the left position, one path of pressure oil goes directly into the rodless chamber of the left hydraulic cylinder I36, and the other path is evenly distributed by the synchronous valve and enters the rodless chamber of the right hydraulic cylinder I36, so that the two sets of hydraulic cylinders I36 extend synchronously, and the oil in the rod chamber returns to the oil tank.

[0032] When the two sets of hydraulic cylinders I36 retract, the reversing valve switches to the right position, and the pressure oil is reversed and delivered to the rod chamber of the two sets of hydraulic cylinders I36. The synchronization valve then distributes the flow equally again, and the two sets of hydraulic cylinders I36 retract synchronously. The oil in the rodless chamber returns to the oil tank. The synchronization valve compensates for the flow deviation in real time to ensure synchronization accuracy.

[0033] Damped spring vibration isolators use the highest quality spring steel, achieving a damping efficiency of over 95% and a service life of over 10 years. They combine the advantages of low frequency and high damping of steel spring vibration isolators, eliminating the inherent resonance amplitude phenomenon of steel springs. Single units can handle various loads from 15kg to 4800kg, with natural frequencies ranging from 1.6Hz to 4.9Hz and a damping ratio of 0.065.

[0034] As described above: Motor I 38 drives a set of lead screws 32 to rotate, and drives another set of lead screws 32 to rotate synchronously through the synchronous pulley and synchronous belt. When the lead screws 32 rotate, the sliding seat 34 slides up and down along the sliding rod 33 to adjust its position to adapt to the height of different types of boilers 4; the hydraulic cylinder I 36 pushes out and pushes the sliding shell 39 close to the boiler 4, so that the top block 310 is in contact with the outer wall of the boiler 4. When the boiler 4 vibrates during operation, the top block 310 transmits the vibration force to the spring damping shock absorber 311. The vibration is buffered by the spring extension and damping action. At the same time, the top block 310 slides in the sliding shell 39 to prevent the vibration from being directly transmitted to the supporting steel frame 2.

[0035] The pushing mechanism 5 includes a steel frame column II 51 and a fixed seat 52; the steel frame column II 51 is provided in two sets and installed on the mounting base 1. The steel frame column II 51 is located between multiple sets of supporting steel frames 2. The fixed seat 52 is welded between the two sets of steel frame columns II 51. Hydraulic cylinders II 53 are provided on both sides of the fixed seat 52. The top end of the hydraulic cylinder II 53 is fixedly connected to the pushing frame 28. The top of the two sets of steel frame columns II 51 is provided with a fixed plate 54. The fixed plate 54 is fixedly connected to the fixed end of the steam header 41.

[0036] The hydraulic cylinders II53 on the same side of the fixed seat 52 are synchronized by using a synchronous hydraulic method to achieve synchronous extension and retraction. That is, the hydraulic cylinders II53 on the same side of the fixed seat 52 are connected in series. When the hydraulic pump starts, it outputs pressure oil, which enters the solenoid directional valve after being stabilized. When the directional valve is energized in the left position, one path of pressure oil goes directly into the rodless chamber of the left hydraulic cylinder II53, and the other path is evenly distributed by the synchronous valve and enters the rodless chamber of the right hydraulic cylinder II53, so that the two sets of hydraulic cylinders II53 extend synchronously, and the oil in the rod chamber returns to the oil tank.

[0037] When the two sets of hydraulic cylinders II53 retract, the reversing valve switches to the right position, and the pressure oil is reversed and delivered to the rod chamber of the two sets of hydraulic cylinders II53. The synchronization valve then distributes the flow equally again, and the two sets of hydraulic cylinders II53 retract synchronously. The oil in the rodless chamber returns to the oil tank. The synchronization valve compensates for the flow deviation in real time to ensure synchronization accuracy.

[0038] As can be seen from the above description: when the spacing of the support steel frame 2 needs to be adjusted, the hydraulic cylinders II 53 on both sides of the fixed seat 52 extend and retract, and the top end pushes the flat push frame 28, causing the support steel frame 2 to slide along the slide rail 101.
