Description

Technical Field

[0001] This utility model relates to the field of thermal power plant equipment maintenance technology, specifically an auxiliary device for boiler maintenance in thermal power plants. Background Technology

[0002] In the daily operation of thermal power plants, boilers, as core power equipment, directly affect the power generation efficiency and safe production of the entire plant. Due to the complex and harsh working environment of thermal power plants, including high temperatures, high dust levels, and strong electromagnetic interference, boilers are more prone to various malfunctions than ordinary industrial boilers, requiring more frequent and professional inspection and maintenance.

[0003] Currently, some boiler maintenance auxiliary devices, such as those disclosed in CN 222374337 U, provide convenience for maintenance work to a certain extent. Through the design of storage boxes and ratchet mechanisms, the position of the storage platform can be adjusted and fixed, facilitating the access and replacement of tools by maintenance personnel. However, these devices exhibit significant limitations when practically applied to boiler maintenance scenarios in thermal power plants.

[0004] The device only has one storage platform. In the maintenance of boilers in thermal power plants, a wide variety of tools are required, ranging from various precision testing instruments to hand tools such as wrenches and screwdrivers of different specifications, as well as spare parts for emergency repairs. The storage space of a single storage platform is extremely limited and cannot meet the storage needs of a large number of tools. This means that maintenance personnel may need to frequently travel between the tool storage area and the maintenance site during the maintenance process, which greatly wastes time and energy, seriously affects the efficiency of maintenance work, and may even cause delays in troubleshooting and repair due to the inability to obtain the required tools in a timely manner, which may adversely affect the normal production and operation of thermal power plants. Therefore, it is necessary to design a corresponding technical solution to solve the existing technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for boiler maintenance in thermal power plants to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary device for boiler maintenance in a thermal power plant includes a mobile vehicle, a maintenance platform mounted on the mobile vehicle, and a lifting mechanism positioned between the maintenance platform and the mobile vehicle. A guardrail is fixedly installed on the maintenance platform, and a box is fixedly mounted on the platform. A roller is rotatably mounted on the side of the box, driven by a drive assembly located inside the box. Multiple holding units are arrayed on the sidewall of the roller. Each holding unit includes a support rod fixedly mounted in parallel on the roller and a storage box mounted between two support plates. A connecting rod is symmetrically fixedly mounted on the top surface of the storage box, and the connecting rod is rotatably mounted on the support rod via a mounting shaft.

[0008] As a further embodiment of this utility model: the driving assembly includes a bevel gear set, a hollow rod, a driving rod, a first fixed plate, a second fixed plate, and a spring. The first fixed plate and the second fixed plate are both fixedly installed inside the housing. The driving rod is movably installed on the first fixed plate via the spring. The hollow rod is rotatably installed on the bottom surface of the second fixed plate. The hollow rod is connected to the roller drive via the bevel gear set. The side wall of the hollow rod is provided with an array of multiple strip-shaped holes. The bottom end of the driving rod is movably inserted into the hollow rod. The side wall of the driving rod is fixedly provided with a round rod that slides and adapts to the strip-shaped holes. The side wall of the driving rod is also fixedly provided with an array of multiple strip-shaped protrusions. The first fixed plate is provided with a sliding groove for the strip-shaped protrusions to slide and adapt.

[0009] As a further embodiment of this utility model: the top of the drive rod passes through the housing and is fitted with a knob.

[0010] As a further embodiment of this utility model: a protective frame is also rotatably installed inside the guardrail, the protective frame is connected to the guardrail by multiple chains, and a safety net is installed inside the protective frame.

[0011] As a further embodiment of this utility model, the side of the guardrail is also symmetrically and rotatably fitted with limiting components.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The arrangement of the box, roller and multiple holding units in this utility model provides tool storage space, which is different from the limited space of a single box platform in the prior art. It greatly increases the number of tools that can be stored. Moreover, as the roller is driven to rotate, the multiple storage boxes can always be set vertically under the action of the tools and their own gravity, which makes it convenient for maintenance personnel to take out the tools in different storage boxes at any time and improve maintenance efficiency.

[0014] 2. The protective frame and safety net of this utility model provide additional safety protection for maintenance personnel. When maintenance personnel are working at heights, the protective frame can be rotated and unfolded. The safety net can effectively prevent personnel from falling accidentally. Multiple chains ensure that the protective frame can rotate flexibly and is firmly connected, thus enhancing the safety performance of the maintenance platform. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Example 1

[0023] Please see Figure 1-5An auxiliary device for boiler maintenance in a thermal power plant includes a mobile vehicle body 1, a maintenance platform 3 mounted on the mobile vehicle body 1, and a lifting mechanism 2 positioned between the maintenance platform 3 and the mobile vehicle body 1. A guardrail 4 is fixedly installed on the maintenance platform 3, and a housing 5 is fixedly mounted on the maintenance platform 3. A roller 6 is rotatably mounted on the side of the housing 5. The roller 6 is driven by a driving assembly located inside the housing 5. Multiple holding units 7 are arrayed on the side walls of the roller 6. Each holding unit 7 includes a support rod fixedly mounted side-by-side on the roller 6 and a support rod mounted on two... The storage boxes 9 between the support plates 8 have connecting rods 10 fixedly and symmetrically installed on their top surfaces. The connecting rods 10 are rotatably mounted on the support rods via mounting shafts 11. The arrangement of the box body 5, roller 6, and multiple holding units 7 provides tool storage space. Unlike the limited space of a single storage platform in the prior art, this greatly increases the number of tools that can be stored. Furthermore, as the roller 6 is driven to rotate, the multiple storage boxes 9 can always be vertically positioned under the action of the tools and their own gravity, making it convenient for maintenance personnel to access tools in different storage boxes 9 at any time and improving maintenance efficiency.

[0024] The drive assembly includes a bevel gear set 20, a hollow rod 16, a drive rod 14, a first fixing plate 12, a second fixing plate 13, and a spring 19. The first fixing plate 12 and the second fixing plate 13 are both fixedly installed inside the housing 5. The drive rod 14 is movably mounted on the first fixing plate 12 via the spring 19. The hollow rod 16 is rotatably mounted on the bottom surface of the second fixing plate 13. The hollow rod 16 is connected to the roller 6 via the bevel gear set 20. Multiple strip-shaped holes 17 are arrayed on the sidewall of the hollow rod 16. The bottom end of the drive rod 14 is movably inserted into the hollow rod 16. A round rod 18 that slides and adapts to the strip-shaped holes 17 is fixedly provided on the sidewall of the drive rod 14. Multiple strip-shaped protrusions are also arrayed and fixedly provided on the sidewall of the drive rod 14. A sliding groove is provided on the first fixing plate 12 for the strip-shaped protrusions 15 to slide and adapt to each other. This drive assembly is designed... When the drive rod 14 is in its initial state, the strip protrusion on the drive rod 14 is locked in the groove on the first fixed plate 12, and the drive rod 14 cannot rotate. At this time, the hollow rod 16 will also not rotate, thus fixing the roller 6 and preventing the roller 6 from rotating arbitrarily and affecting the retrieval of tools. When it is necessary to rotate the roller 6, the drive rod 14 needs to be pressed down. After the strip protrusion 15 separates from the groove, the drive rod 14 is rotated. Under the action of the round rod 18, the hollow rod 16 can be rotated, and through the meshing transmission of the bevel gear set 20, the roller 6 can be rotated, making it convenient to adjust the position of the storage box 9 to retrieve the required tools. After the pressure on the drive rod 14 is stopped, the drive rod 14 is reset upward under the action of the spring 19. By slightly rotating the drive rod 14, the strip protrusion 15 can be locked back in the groove, and the roller 6 can be fixed. The operation is simple and convenient and the fixing effect is reliable.

[0025] In addition, the top of the drive rod 14 passes through the housing 5 and is equipped with a knob 21. The knob 21 is designed to facilitate the operation of the drive rod 14 by maintenance personnel. By rotating the knob 21, the drive rod 14 can be easily pressed down or rotated. Compared with directly operating the drive rod 14, it is more labor-saving and convenient, and further improves the efficiency of adjusting the position of the roller 6.

[0026] Example 2

[0027] This embodiment is an improvement on embodiment 1, specifically as follows:

[0028] Please see Figure 1 and Figure 2 The guardrail 4 is also equipped with a rotatable guardrail frame 22. The guardrail frame 22 is connected to the guardrail 4 by multiple chains, and a safety net 23 is installed inside the guardrail frame 22. The guardrail frame 22 and the safety net 23 provide additional safety protection for maintenance personnel. When maintenance personnel are working at height, the guardrail frame 22 can be rotated and unfolded. The safety net 23 can effectively prevent personnel from falling accidentally. The multiple chains ensure that the guardrail frame 22 can rotate flexibly and is firmly connected, thus enhancing the safety performance of the maintenance platform 3.

[0029] In addition, the side of the guardrail 4 is also symmetrically and rotatably equipped with a limiting member 24. The limiting member 24 can limit the guardrail 22 after it is flipped into the guardrail 4, preventing the guardrail 22 from unfolding outward, ensuring that the guardrail 22 is neatly stored when not in use, and can be quickly opened and fixed in a suitable position when needed.

[0030] It is worth noting that a damping plate is also provided on the side of the limiting member 24 near the guardrail 4, which can temporarily fix the limiting member 24 after it is rotated to the designated position.

[0031] Working principle:

[0032] During boiler maintenance at a thermal power plant, the device is first moved to the boiler maintenance location using a mobile vehicle 1. The height of the maintenance platform 3 is adjusted using a lifting mechanism 2 according to the required maintenance height. Maintenance personnel stand on the maintenance platform 3, with safety railings 4, a protective frame 22, and a safety net 23 ensuring their safety. When tools need to be retrieved, if the required tools are not in the currently facing storage box 9, the maintenance personnel press down and turn knob 21 to separate the strip-shaped protrusion on the drive rod 14 from the sliding groove on the first fixed plate 12. At this time, the drive rod is rotated... The circular rod 18 on the side wall of the moving rod 14 slides in the strip hole 17 of the hollow rod 16, causing the hollow rod 16 to rotate. The hollow rod 16 drives the roller 6 to rotate through the bevel gear set 20, thereby rotating the storage box 9 containing the corresponding tools to a position that is easy to access. Stop rotating the driving rod 14 and release the knob 21. The driving rod 14 returns to its original position under the action of the spring 19. The strip protrusion is re-locked in the groove to fix the roller 6. The storage box 9 remains vertical under the action of the tools and its own weight, making it easy to access the tools.

[0033] The limiting component 24 can be stored in the protective railing 4 when the protective frame 22 is not in use. When in use, the protective frame 22 can be rotated to unfold the safety net 23 to ensure personnel safety. The entire device effectively solves the problems of limited tool storage and insufficient safety protection in the existing technology through the coordinated work of various components, and meets the actual needs of boiler maintenance in thermal power plants.
