[0003] The application number is CN202311182437.7. The boiler steel frame with adjustable function uses an assembly method to connect the cross support plate with the first support frame and the second support frame, and install the cross support plate around the first support frame and the second support frame through connecting bolts, and then install the connecting frame between two adjacent cross support plates. Finally, the bottom of the inclined support frame is connected with the bottom bracket, and the top is connected with the cross support plate, and the boiler bracket can be assembled. When maintaining the bracket, any part on the detachable bracket can be replaced without affecting the overall bracket. It was found in actual use that the above structure still has the problem of inconvenient adjustment, which is not convenient for adapting to boilers with different support heights and is inconvenient to use.

[0024] Please refer to Figure 1-4, An earthquake-resistant industrial boiler steel frame stable steel structure, including a support component, a lifting component and an earthquake-resistant component. The support component includes a bottom plate 1, a top plate 2 and a sliding frame 3. The four corners of the bottom plate 1 are fixed on the ground.

The output end of the motor 4 penetrates through the top plate 2 and the top wall of the sliding frame 3 and is connected to the screw rod 5. The slider 6 is threadedly connected to the screw rod 5. The slider 6 protrudes from the sliding frame 3 and is also provided with a lifting frame 7 in a U-shape. The earthquake-resistant component includes a support frame 8, a spring 9, a damping telescopic rod 10 and a pressing plate 11. The two free ends of the lifting frame 7 are also provided with an inclined support frame 8 on the side close to the boiler. The spring 9 is sleeved on the damping telescopic rod 10. The upper and lower ends of the spring 9 and the damping telescopic rod 10 are respectively connected to the support frame 8 and the pressing plate 11. The pressing plate 11 is in an inverted L shape.

[0025] Fix the four corners of the bottom plate 1 on the ground to ensure a stable foundation for the entire structure. The fixation of the bottom plate 1 can be achieved through methods such as anchor bolts to ensure its firmness and reliability. Install the sliding frame 3 on the fixed bottom plate 1, and then install the U-shaped top plate 2 above the sliding frame 3, so that the bottom plate 1, the sliding frame 3 and the top plate 2 form a solid frame structure. Install the motor 4 above the top plate 2, and make its output end penetrate through the top plate 2 and the top wall of the sliding frame 3 and connect to the screw rod 5. Install the screw rod 5 and the slider 6 in the chute of the sliding frame 3 to ensure a good threaded connection between the slider 6 and the screw rod 5. Install a U-shaped lifting frame 7 on the slider 6 so that the slider 6 can drive the lifting frame 7 to move up and down in the chute. Install an inclined support frame 8 on the two free ends of the lifting frame 7 on the side close to the boiler. Sleeve the spring 9 on the damping telescopic rod 10, and then connect the upper and lower ends of the spring 9 and the damping telescopic rod 10 to the support frame 8 and the pressing plate 11 respectively. Install an inverted L-shaped buffer pad 15 below the pressing plate 11 and ensure that the inclined surface 16 below the buffer pad 15 faces the boiler. The spring 9 and the damping telescopic rod 10 contract stably, and the buffer pad 15 presses the boiler stably, achieving a good earthquake-resistant effect.

[0026] During actual use, guide rods 12 penetrating through the top plate 2 are also provided on the left and right side walls of the lifting frame 7. Install an inverted L-shaped buffer pad 15 below the pressing plate 11 and ensure that the inclined surface 16 below the buffer pad 15 faces the boiler. Each group of guide rods 12 on the side wall of the lifting frame 7 is arranged in two groups symmetrically. First reinforcing ribs 13 are also provided on the guide rods 12 and the support frame 8. The first reinforcing ribs 13 are provided below the top plate 2. Install an inverted L-shaped buffer pad 15 below the pressing plate 11 and ensure that the inclined surface 16 below the buffer pad 15 faces the boiler.

[0027] In this embodiment, the sliding frame 3 is further provided with a second reinforcing rib 14 connected to the top plate 2 and the bottom plate 1 , and an inverted L-shaped buffer pad 15 is installed under the pressure plate 11 , ensuring that the inclined surface 16 under the buffer pad 15 faces the boiler.

[0028] In this embodiment, a frame 17 is further provided between the bottom plate 1 and the top plate 2, and a guide groove is further provided on the frame 17. A guide block 18 adapted to the guide groove is further provided on the lifting frame 7. The guide block 18 and the guide groove are both T-shaped. The frame 17 is slidably connected to the guide block 18 to facilitate lifting and lowering and ensure the stability of the equipment support.

[0029] When the boiler vibrates, the vibration energy is transferred to the pressure plate 11. This energy is then transferred to the spring 9 and the damping telescopic rod 10. These springs 9 and the damping telescopic rod 10 deform under the influence of the vibration, absorbing and buffering the vibration energy. This deformation reduces the impact of the vibration on the steel frame and, consequently, the overall structural impact. Furthermore, components such as the support frame 8, guide rods 12, and reinforcement ribs also partially absorb the vibration energy, further enhancing the structure's seismic resistance.
