The operating efficiency and safety of the boiler are directly related to the power generation capacity and economic benefits of the entire power plant. Therefore, regular maintenance and overhaul of the boiler is an important measure to ensure the stable operation of the power plant. With the increase of operating time, the heating surface, pipelines, valves and other components inside the boiler will gradually age and wear due to factors such as high temperature, high pressure and corrosion. If timely maintenance is not carried out, it may cause equipment failure and even cause safety accidents. With the development of science and technology, the design and manufacturing technology of boilers are constantly improving. New materials, monitoring systems and automation technologies are applied to boiler maintenance, which improves the efficiency and quality of maintenance. The maintenance cost of the boiler is part of the operating cost of the thermal power plant. A reasonable maintenance plan can reduce the maintenance cost and improve the economic benefits of the power plant while ensuring the safe operation of the equipment. In summary, the maintenance of the boiler of a thermal power plant is a comprehensive work involving many factors such as safety, environmental protection, efficiency, technology and economy, which is of great significance to ensure the stable operation and sustainable development of the power plant.

The platforms 1 on both sides are connected by connecting grooves and connecting plug plates, connecting members 2 are provided on both sides of the outer wall of the platform 1, and a slidable bar frame 3 is provided on the outer wall of the connecting member 2. When the platforms 1 on both sides are connected, the connecting member 2 can slide inside the bar frame 3, and the connecting member 2 can rotate inside the bar frame 3, so as to fold the platform 1.

[0027] A vertical cylinder 4 is provided on the front and rear sides of the bottom end of the platform 1. The vertical cylinder 4 is used to provide an installation position for the spring 5. A spring 5 is provided inside the vertical cylinder 4. An extrusion piece 6 is provided at the bottom end of the spring 5. The extrusion piece 6 can extrude the spring 5. The spring 5 cooperates with the extrusion piece 6 to provide shock absorption and buffering for the platform 1 to increase the comfort of the maintenance personnel. While extruding, the extrusion piece 6 can slide up and down inside the vertical cylinder 4. The extrusion piece 6 is slidably connected to the vertical cylinder 4. A support assembly is provided on the outer wall of the extrusion piece 6. The support assembly is used to support and fix the platform 1 to the position where it needs to be installed inside the boiler. Bearing seats 12 are provided on both sides of the bottom end of the left platform 1. The bearing seats 12 are used to support the studs 13. The studs 13 can rotate inside the bearing seat 12. A rotatable stud 13 is provided inside the bearing seat 12. A rotating part is provided at the center of the outer wall of the stud 13. A fixing assembly is provided on the outer wall of the stud 13. The fixing assembly is used to fix the platform 1 after assembly.

[0028] Specifically, the supporting assembly includes a rotating member 7, which is arranged on the outer wall of the extrusion member 6. The rotating member 7 can rotate on the outer wall of the extrusion member 6. The rotating member 7 can be unfolded and stored from the bottom end of the platform 1 when rotating. A threaded barrel 8 is arranged on the outer side of the rotating member 7. An adjusting rod 9 is arranged inside the threaded barrel 8. The adjusting rod 9 moves left and right inside the threaded barrel 8 to adjust the length. The platform 1 is extruded and fixed inside the boiler in cooperation with the supporting member 11. An adjusting member 10 is arranged on the outer wall of the adjusting rod 9. A supporting member 11 is arranged on the outer side of the adjusting rod 9. A rotating protrusion is arranged at the connection position between the adjusting rod 9 and the supporting member 11. A rubber gasket is arranged on the outer side of the supporting member 11. The rubber gasket is made of hard rubber. The supporting member 11 contacts the inner wall of the boiler. After contact, continuing to rotate the adjusting rod 9 will not drive the supporting member 11 to rotate. The rubber is used to increase friction and provide stability for the installation of the platform 1.

[0029] More specifically, the fixing assembly includes a fixing part 14, which is arranged on both sides of the outer wall of the stud 13. The stud 13 can drive the fixing part 14 to move inward or outward at the same time during rotation. A stabilizing part 15 is arranged on the left side of the fixing part 14. The stabilizing part 15 is used to prevent the fixing part 14 from rotating when the stud 13 rotates. The other end of the stabilizing part 15 is connected to the bearing seat 12. A fixing block 16 is arranged on the right side of the fixing part 14. When the fixing part 14 moves outward, it can be inserted into the inside of the fixing block 16. Conversely, when it moves inward, it can be pulled out from the back of the fixing block 16 to cancel the fixing work. The fixing block 16 is connected to the platform 1 on the right side. A sleeve is arranged at the connection position between the fixing part 14 and the stabilizing part 15, and the sleeve can slide on the outer wall of the stabilizing part 15.

[0030] When the utility model is in use, the folded platform 1 is placed inside the boiler, and then the platform 1 is unfolded outward. During the unfolding process, the connecting piece 2 rotates inside the bar frame 3. After the unfolding, the platforms 1 on both sides are assembled through the connecting protrusions and the connecting grooves. After the assembly, the studs 13 are rotated, and the studs 13 rotate inside the bearing seat 12. During the rotation of the studs 13, the fixing piece 14 is driven to move outward. When the fixing piece 14 moves outward, it slides on the outer wall of the stabilizing piece 15 at the same time, and is inserted into the interior of the fixing block 16 during the movement. After the insertion, the fixing work of the platform 1 is stabilized.

[0031] When the platform 1 needs to be fixed inside the boiler, the rotating member 7 rotates on the outer wall of the extrusion member 6, and during the rotation, the threaded tube 8 is driven to rotate outward and unfold from the bottom end of the platform 1. After unfolding, the adjusting member 10 is rotated. When the adjusting member 10 rotates, it drives the adjusting rod 9 to move outward inside the threaded tube 8, and when moving outward, it drives the supporting member 11 to move outward at the same time, so that the supporting member 11 fits with the inside of the boiler. After fitting, the adjusting member 10 continues to be rotated to increase the extrusion force of the supporting member 11, thereby completing the fixing of the platform 1. During the maintenance process, the spring 5, the vertical tube 4 and the extrusion member 6 are used to perform buffering and weight reduction work, thereby increasing the comfort of the maintenance personnel.
