[0030] Please refer to Figures 1-6 The present application provides a technical solution: a heat-compensated supporting structure for a boiler flue gas and coal pipeline, comprising: a support seat A1, one side of the support seat A1 is provided with a support seat B2, and the surfaces of the support seat A1 and the support seat B2 are respectively provided with arc-shaped grooves 9;

[0031] A plug-in plate 10 is arranged on the surface of the support seat A1, and the inside of the support seat B2 is provided with a plug-in groove 11 for inserting the plug-in plate 10;

[0032] Cavities 8 are respectively arranged in the interiors of the support seat A1 and the support seat B2, and the interiors of the two groups of cavities 8 are provided with limiting mechanisms.

[0034] The side of the moving plate 24 is connected with a sliding block 23, which is fixedly arranged between the moving plate 24, the inner part of the support seat A1 and the support seat B2 is respectively provided with a sliding groove 22 for slidingly connecting the sliding block 23, the sliding groove 22 is integrally formed between the support seat A1 and the support seat B2, and the sliding groove 22 provides guidance for the sliding of the sliding block 23.

[0035] The inner part of the sliding groove 22 is connected with a limiting rod 20, the sliding block 23 is slidingly connected on the surface of the limiting rod 20, the limiting rod 20 not only provides guidance for the sliding of the sliding block 23, but also prevents the sliding block 23 from being separated from the sliding groove 22, and the surface of the limiting rod 20 is sleeved with a spring A21 between the sliding groove 22 and the sliding block 23.

[0036] The inner part of the support seat B2 is provided with a fixing mechanism, the L-shaped plate 15 is inserted into the inner part of the plug-in plate 10 through the cylinder 13 of the fixing mechanism, so that the L-shaped plate 15 fixes the plug-in plate 10 and the support seat A1.

[0037] The fixing mechanism comprises a positioning cavity 12 provided in the inner part of the support seat B2, the positioning cavity 12 is integrally formed between the support seat B2, the cylinder 13 is connected in the inner part of the positioning cavity 12, the L-shaped plate 15 is slidingly connected in the inner part of the positioning cavity 12, and the output end of the cylinder 13 is connected to the side of the L-shaped plate 15, the L-shaped plate 15 is inserted into the inner part of the plug-in plate 10, and the L-shaped plate 15 is used for fixing the plug-in plate 10.

[0038] The inner side wall of the positioning cavity 12 and one side of the L-shaped plate 15 are connected with a spring B17, the inner part of the positioning cavity 12 is provided with a light rod 14, and the L-shaped plate 15 is slidingly connected on the surface of the light rod 14, the light rod 14 plays a guiding role to ensure the stable movement of the L-shaped plate 15.

[0039] The inner part of the plug-in plate 10 is provided with a positioning groove 16 for inserting the L-shaped plate 15, and the positioning groove 16 is integrally formed between the plug-in plate 10.

[0040] One side of the support seat A1 is connected with a positioning rod 3, which is fixedly arranged between the support seat A1, one side of the positioning rod 3 is connected with a side plate 4, which is fixedly arranged between the positioning rod 3, one side of the side plate 4 is connected with a bolt 5, and the bolt 5 penetrates the inner part of the wall or the boiler for fixing.

[0041] Specifically, in use, the support seat A1 and the support seat B2 are initially connected through the plug-in plate 10 and the plug-in groove 11, the plug-in plate 10 on the surface of the support seat A1 is inserted into the plug-in groove 11 in the inner part of the support seat B2, and the plug-in design facilitates the quick butt joint of the support seat A1 and the support seat B2, and prepares for subsequent fixing and pipeline support.

[0042] The boiler flue gas and air coal pipeline is placed on the arc-shaped groove 9 on the surface of the support seat A1 and the support seat B2. The arc-shaped groove 9 is designed to better fit the shape of the pipeline, increase the contact area, and improve the stability of the support. Then, the pipeline is clamped by operating the limiting mechanism. The rotating rod 6 is rotated, and the rotating rod 6 drives the screw rod 7 to rotate. Since the screw rod 7 is connected to the moving plate 24 and penetrates the support seat A1 and the support seat B2, the rotation of the screw rod 7 causes the moving plate 24 to move along the axial direction of the screw rod 7 in the cavity 8. The sliding block 23 on the side of the moving plate 24 slides in the sliding groove 22. The limiting rod 20 inside the sliding groove 22 not only provides guidance for the sliding of the sliding block 23, but also prevents the sliding block 23 from disengaging from the sliding groove 22. At the same time, the spring A21 on the surface of the limiting rod 20 plays a buffering and fine-tuning role during the movement of the moving plate 24, avoiding damage to the pipeline caused by excessive clamping force. When the moving plate 24 moves, the concave frame 18 is moved through the connecting column 25. The rollers 19 inside the concave frame 18 move accordingly. Finally, the rollers 19 clamp the pipeline in the arc-shaped groove 9, ensuring that the pipeline is stably placed on the support structure. The small gap between the arc-shaped groove 9 and the outer wall of the pipeline is compensated by the mutual approach of the two groups of rollers 19, allowing the device to better limit the pipeline.

[0043] During the clamping process of the rollers 19, the threads on the surface of the screw rod 7 have a self-locking function, allowing the screw rod 7 to remain stationary after reaching the desired clamping position. Regardless of whether the pipeline is subjected to external forces, the screw rod 7 will not rotate on its own, ensuring that the clamping force exerted by the rollers 19 on the pipeline remains constant. This provides a continuous and stable support force for the pipeline, preventing damage caused by changes in clamping force and extending the service life of the pipeline and the support structure.

[0044] After the pipeline is placed and clamped, the fixed mechanism is started to further fix the support seat A1 and the support seat B2. The cylinder 13 in the positioning cavity 12 inside the support seat B2 is activated. The output end of the cylinder 13 pushes the L-shaped plate 15 to slide along the light rod 14 in the positioning cavity 12. The light rod 14 serves as a guide to ensure smooth movement of the L-shaped plate 15. The L-shaped plate 15 is inserted into the positioning slot 16 inside the insertion plate 10, thereby fixing the insertion plate 10 with the support seat A1, enhancing the stability of the entire support structure and preventing the support seat A1 and the support seat B2 from moving relative to each other when the pipeline is under stress. The spring B17 connected to one side of the L-shaped plate 15 on the inner wall of the positioning cavity 12 plays a buffering and resetting role during the insertion and removal of the L-shaped plate 15.

[0045] The positioning rod 3, the side plate 4, and the bolt 5 on one side of the support seat A1 are used to install the entire support structure to a specified location.

[0046] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
