Description

Technical Field

[0001] This utility model relates to the technical field of power plant chimney repair devices, and in particular to a chimney inner wall substrate repair device. Background Technology

[0002] As a key facility for industrial production to emit flue gas, the inner wall of a chimney is constantly exposed to a complex environment of high temperature, corrosive flue gas, and airflow impact, which can lead to corrosion, peeling, and cracking damage. These problems not only affect the structural safety and service life of the chimney, but also cause flue gas leakage and environmental pollution. Therefore, timely and effective inner wall repair is an important part of ensuring the safe operation of industry. Related repair devices are widely used in chimney maintenance in the power, chemical, and metallurgical industries. Early repair work relied on manual labor. Workers used scaffolding, suspended platforms, trowels, and spray guns to repair damaged areas. This method, consisting of manual labor, basic support tools, and simplified repair tools, suffered from high labor intensity, low efficiency, and quality heavily influenced by skill levels. Furthermore, the harsh environment of high altitudes and confined spaces posed significant safety risks for workers. To address these issues, existing repair devices utilize mechanical structures to replace some manual labor. They feature a walking mechanism that can move along the inner wall for autonomous movement, and are equipped with spray guns and grouting heads to perform various tasks. Some devices also incorporate adjustable support structures to accommodate different diameters. These improvements have, to a certain extent, addressed these problems. While improving efficiency, reducing labor intensity, and enhancing safety, the existing equipment still suffers from reduced repair accuracy due to shaking. Although the equipment ensures basic positioning through the contact of the traveling wheels and the adjustment of the support arms, avoiding the large-scale deviations of early manual operations, the traveling wheels are mostly rigidly connected. When encountering uneven inner walls or protruding brick joints, vibrations are generated and transmitted to the whole system. The adjustment of the support arms is mostly a staged and discrete adjustment, which is difficult to adapt to slight changes in diameter in real time, resulting in uneven contact force. Under the action of airflow or inertia, it will cause deviation and shaking, which in turn affects the positioning accuracy of the actuator, causing uneven coating and grouting deviation, thus affecting the repair effect.

The buffer column 201 of the stabilizing mechanism 2 is fixed on the adjacent side of the two protective blocks 4 to initially buffer the impact force. The limiting column 202 of the buffer column 201 fixes and supports the limiting block 203, which restricts the position of the spring 204. To prevent the spring 204 from shifting, the spring 204 absorbs and mitigates the impact force through elastic deformation. The rubber pad 205 of the spring 204 increases the friction with the clamping block 206, playing a buffering and protective role.

The tops of the two fixed blocks 301 are fixedly connected to the top left and right sides of the upper protective block 4, respectively. This connection method enables the fixed blocks 301 and the protective block 4 to form a stable overall structure, enhancing the installation firmness of the displacement mechanism 3. Two slide rails 302 are fixedly connected to adjacent sides of the two fixed blocks 301. The slide rails 302 provide a guide path for the sliding sleeve 304, ensuring that the sliding sleeve 304 moves smoothly along a preset direction.

The top of the slide sleeve 304 is fixedly connected to the clamping shell 305. The clamping shell 305 can be used to accommodate and fix the connection end of the peripheral equipment, providing a structural basis for the connection between the peripheral equipment and the device.

[0019] Reference Figure 1 , Figure 5 and Figure 6Each of the two protective blocks 4 has a limiting groove 5 on its opposite side. The limiting groove 5 provides installation space for the fixing component 6, ensuring the stability of the fixing component 6. The fixing component 6 is installed on the inner wall of the limiting groove 5. The fixing component 6 can enhance the connection between the device and the inner wall of the chimney and prevent the device from shifting. The fixing component 6 includes two limiting plates 601. The first limiting plate 601 can cooperate with the second limiting plate 603 to form a clamping structure to enhance the fixing effect. The front and rear ends of the left side of the outer wall of the first limiting plate 601 are threaded with screws. Screw 602 securely connects limiting plate 601 and limiting plate 603, ensuring reliable connection. The right end of screw 602 is threadedly connected to limiting plate 603. Limiting plate 603 works in conjunction with limiting plate 601 to clamp the external structure and enhance fixation strength. Hexagonal blocks 604 are fixedly connected to the front and rear ends of the right side of limiting plate 601. Hexagonal blocks 604 provide an installation carrier for screw 605, facilitating tightening and fixing. The inner wall of hexagonal blocks 604... The screw 605 is threaded to further lock the fixing component 6 and the protective block 4 to prevent the fixing component 6 from loosening. The bottom middle of the lower protective block 4 is fixedly connected to the limiting shaft 8, which can position and support the motor 7 to ensure the stability of the motor 7 during operation. The motor 7 is set at the bottom of the limiting shaft 8. The motor 7 can provide power output to drive the rotating shaft 9 to rotate. The output end of the motor 7 is fixedly connected to the rotating shaft 9, which can transmit the power of the motor 7 to the turbine blade 10 to drive the turbine blade 10 to rotate. The outer wall of the rotating shaft 9 is fixedly connected to the turbine blade 10, which can grind or clean the damaged parts of the inner wall of the chimney to prepare for subsequent repair work. The adjacent side of the two sealing blocks 1 is fixedly connected to the storage block 12, which can be used to store the repair fluid material to ensure a sufficient supply of repair material. The top of the inner wall of the storage block 12 is fixedly connected to the inlet 11, which can serve as a channel for the repair fluid to enter the storage block 12, making it convenient to add repair material to the storage block 12. Specifically, the limiting groove 5 of the protective block 4 provides installation space for the fixing component 6. The limiting plate 601 and the limiting plate 603 of the fixing component 6 are fastened together by the screw 602 to form a clamping structure. The screw 605 on the hexagonal block 604 locks the fixing component 6 and the protective block 4, enhancing the connection stability between the device and the inner wall of the chimney and preventing the overall displacement of the device. The limiting shaft 8 of the lower protective block 4 positions and supports the motor 7. The motor 7 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the turbine blade 10 to rotate, grinding and cleaning the damaged parts of the inner wall of the chimney, preparing for subsequent repair. The two sealing blocks 1 are connected to the storage block 12. The storage block 12 stores the repair fluid. The inlet 11 serves as the channel for the repair fluid to enter the storage block 12, ensuring the supply of repair materials.

[0020] Working principle: When vibration occurs, the buffer column 201 first contacts the protective block 4, and the clamping block 206 immediately fits tightly against the outer wall of the storage block 12 to prevent the storage block 12 from axial or radial displacement due to violent shaking. The rubber pad 205 on the inner side of the clamping block 206 transmits the impact force to the spring 204, and the spring 204 forms a second layer of flexible buffer. The limiting block 203 strictly limits the maximum deformation of the spring 204, and the limiting column 202 provides a rigid support frame for the entire buffer structure by rigidly fixing the spatial position of the limiting block 203, preventing the buffer component itself from displacing due to force, ensuring the coordination accuracy of the multi-level buffer mechanism, solving the problems of uneven coating thickness and grouting deviation from the crack center caused by shaking in the existing technology, and improving the stability of the chimney inner wall repair quality. Furthermore, when reinforcement with peripheral equipment is required, the connection end of the peripheral equipment is inserted into the clamping shell 305 and locked by the latch 306 to prevent relative displacement between the peripheral equipment and the main body of the device. The clamping shell 305 can move flexibly in the horizontal direction under the guidance of the sliding sleeve 304, which facilitates precise alignment according to the connection position of the peripheral equipment. When it is necessary to inject repair fluid, the top cover 307 is opened, and the repair fluid can be directly injected into the storage block 12 through the injection channel of the top cover 307. The reinforcement system remains in a stable locked state to prevent the equipment from shaking during the injection operation, further ensuring the continuity and stability of subsequent repair operations, and effectively solving the problem of conflict between the traditional reinforcement system and the injection function.
