Description

Technical Field

[0001] This application relates to the technical field of tower maintenance, and in particular to an auxiliary device for the maintenance of power towers. Background Technology

[0002] In modern power infrastructure, power transmission towers play a crucial role in supporting transmission lines, and their stable operation is essential for ensuring the reliability of power supply. Regular inspection and maintenance are indispensable to ensure that power transmission towers are always in good condition.

[0003] Currently, when performing high-altitude maintenance on power transmission towers, the common practice is to use steel wire ropes to lift the hoisting pod and maintenance personnel to the appropriate maintenance position. Under normal weather conditions, this method effectively meets maintenance needs and provides a relatively convenient working platform for maintenance personnel. However, in severe windy weather, because the hoisting pod is only connected to the power transmission tower by steel wire ropes, it is prone to swaying under the continuous force of strong winds. Maintenance personnel inside the swaying pod constantly face the possibility of danger due to loss of balance. The swaying also makes it difficult for maintenance personnel to accurately locate the maintenance area, turning what should be a simple operation into an extremely difficult one, significantly extending maintenance time and greatly reducing the overall efficiency of the maintenance work.

[0004] Regarding the aforementioned technologies, the inventors believe that there are drawbacks in using steel wire ropes to lift the hoisting container and maintenance personnel to the corresponding maintenance position for maintenance work. In windy weather, the hoisting container is prone to swaying, which poses a high safety risk to maintenance personnel and reduces the efficiency of maintenance work. Utility Model Content

[0005] To address the issue that hoisting gantry and maintenance personnel are easily swayed in windy weather, posing a high safety risk to maintenance personnel and reducing maintenance efficiency when using wire ropes to lift gantry cranes and personnel to the appropriate maintenance positions, this application provides an auxiliary device for power tower maintenance.

[0006] This application provides an auxiliary device for the maintenance of power transmission towers, which adopts the following technical solution:

[0007] An auxiliary device for the maintenance of power transmission towers includes a hoisting box. Telescopic rods are installed on both sides of the hoisting box, and locking components are installed at the ends of the telescopic rods to lock the tower body. An electromagnet is installed on the side of the hoisting box near the locking components. An installation housing is provided inside the hoisting box, and multiple driving components are installed inside the installation housing. The multiple driving components drive the electromagnet so that the electromagnet magnetically attracts the tower body. A protective component for protecting maintenance personnel is installed inside the hoisting box. By adopting the above technical solutions, the hoisting cassette provides maintenance personnel with a high-altitude working platform to carry maintenance tools and personnel. The telescopic rod can adjust the distance between the hoisting cassette and the tower, allowing the hoisting cassette to accurately approach the maintenance location. The locking assembly firmly fixes the hoisting cassette to the tower, preventing it from shaking or shifting during operation. The electromagnet, under the control of the drive component, adheres to the tower, further enhancing connection stability and resisting external forces such as strong winds. The protective components provide comprehensive protection for the safety of maintenance personnel, preventing falls during high-altitude operations. This improves the safety and stability of power tower maintenance work and ensures efficient maintenance.

[0008] Optionally, a fixing plate is installed at the end of the telescopic rod, and the locking assembly is installed on the other side of the fixing plate. The locking assembly includes a first locking member and a second locking member. One end of the first locking member and one end of the second locking member are hinged together, and the other end of the first locking member and the other end of the second locking member are connected to a locking bolt. A locking nut is threaded onto the locking bolt. By adopting the above technical solution, the fixing plate provides a stable installation foundation for the locking assembly, enhancing the stability of the connection between the locking assembly and the telescopic rod. The hinge of the first and second locking members allows the locking assembly to adapt to towers of different shapes and sizes. The locking bolt and locking nut work together to adjust the locking force according to the actual situation of the tower, ensuring a tight connection between the hoisting box and the tower body, effectively preventing the hoisting box from loosening during operation, and providing a reliable working platform for maintenance personnel.

[0009] Optionally, the first locking member has a first connecting member at its end, and the first connecting member has a first threaded hole. The second locking member has a second connecting member at its end, and the second connecting member has a second threaded hole. The locking bolt passes through the first threaded hole and the second threaded hole in sequence and is threadedly connected to the locking nut to connect the first locking member and the second locking member. By adopting the above technical solution, the first connecting member and the second connecting member provide a precise positioning structure for the connection between the first locking member, the second locking member, and the locking bolt, respectively. The first threaded hole and the second threaded hole ensure the accuracy and stability of the locking bolt installation, allowing the locking bolt to evenly tighten the first locking member and the second locking member, enhancing the overall connection strength of the locking assembly, preventing the hoisting box from shaking due to weak connection, and ensuring the safety of maintenance personnel.

[0010] Optionally, a spring is fitted onto the locking bolt, and the spring is located between the locking bolt and the first connecting member. By adopting the above technical solution, the spring plays a buffering role during the locking process. When tightening the locking nut, the spring can prevent damage to the tower body and locking components caused by excessive instantaneous force. When the power tower is subjected to vibration or wind, the spring can absorb some energy, preventing the locking bolt from loosening, ensuring that the connection between the hoisting box and the tower body remains stable, extending the service life of the equipment, and improving the safety of operation.

[0011] Optionally, the side of the hoisting box is provided with a through slot for the electromagnet to pass through. The mounting housing is installed inside the hoisting box, located on one side of the through slot. The fixed end of the drive component is fixedly mounted on the mounting housing, and the output end of the drive component is connected to the electromagnet. By adopting the above technical solution, the through slot provides a movement channel for the electromagnet, allowing it to smoothly approach or move away from the tower body, realizing magnetic attraction and separation operations with the tower body. The mounting housing provides a stable installation space for the drive component. Supported by the mounting housing, the drive component precisely controls the movement of the electromagnet, enabling it to accurately adhere to the tower body, thus enhancing the reliability of the connection between the hoisting box and the tower body.

[0012] Optionally, the protective assembly includes fixing components and a protective suit. The fixing components are installed on both sides of the hoisting box, and connecting ropes are attached to the fixing components. The other ends of multiple connecting ropes are connected to the protective suit, which is equipped with a fall arrestor rope. The end of the fall arrestor rope is connected to an anti-detachment hook for connecting to the tower body. By adopting the above technical solution, the fixing components secure the connecting ropes to both sides of the hoisting box, providing stable connection points for the protective suit. The connecting ropes restrict the range of movement of maintenance personnel inside the hoisting box, preventing accidental falls. The protective suit is worn directly on the maintenance personnel, evenly distributing the tension of the connecting ropes and fall arrestor ropes, protecting the maintenance personnel's body. In the event of an accidental fall, the suit can promptly catch the maintenance personnel, preventing a direct fall to the ground and greatly reducing the safety risks to the maintenance personnel.

[0013] Optionally, a storage box is provided inside the hoisting box, with multiple partitions spaced apart inside the storage box, and a cover is hinged to the top of the storage box. By adopting the above technical solution, the storage box provides a centralized storage space for maintenance tools and parts, avoiding random placement inside the hoisting box and preventing items from being scattered, lost, or damaged when the hoisting box shakes. The partitions divide the interior of the storage box into multiple independent areas, facilitating the classification and storage of different tools and parts, improving the efficiency of maintenance personnel in retrieving items, and the cover prevents dust and moisture from entering the storage box, protecting the items inside.

[0014] Optionally, the top of the hoisting box is equipped with multiple lifting rings for connecting steel wire ropes.

[0015] By adopting the above technical solution, the lifting rings provide a connection point between the lifting box and the wire rope. Multiple lifting rings are evenly distributed on the top of the lifting box, which can make the lifting box more evenly stressed during the lifting process and avoid the lifting box tilting or shaking due to uneven stress.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. When repairing power transmission towers, this equipment uses a telescopic rod to drive the locking assembly, which is then moved to the corresponding position on the tower body. The locking assembly is then locked onto the tower body, achieving initial positioning and fixation. The driving component drives the electromagnet to approach and fit against the corresponding position on the tower body. Under the synergistic effect of the locking assembly and the electromagnet, the connection stability between the hoisting box and the tower body is significantly improved, further enhancing the safety, stability, and efficiency of maintenance personnel performing high-altitude maintenance operations on power transmission towers.

[0018] 2. The protective clothing is connected to the hoisting box by connecting ropes to form a whole. When maintenance personnel move inside the hoisting box, the connecting ropes restrict the range of motion of the protective clothing. If the maintenance personnel accidentally lose their balance or the hoisting box shakes, the protective clothing will be pulled to prevent the maintenance personnel from falling from the hoisting box, thus providing basic safety protection for the maintenance personnel.

[0026] The following is in conjunction with the appendix Figure 1 and Figure 2 This application will be described in further detail.

[0027] This application discloses an auxiliary device for power tower maintenance, referring to... Figure 1 and Figure 2 The auxiliary equipment for power tower maintenance includes a hoisting box 1. Telescopic rods 2 are installed on both sides of the hoisting box 1. Locking components 3 are installed at the ends of the telescopic rods 2 to lock the tower body of the power tower. An electromagnet 4 is installed on the side of the hoisting box 1 near the locking components 3. The hoisting box 1 is equipped with a mounting housing 13. Multiple driving components 5 are installed in the mounting housing 13. The multiple driving components 5 drive the electromagnet 4 so that the electromagnet 4 is magnetically attracted to the tower body. A protective component 6 for protecting maintenance personnel is installed inside the hoisting box 1.

[0028] In this auxiliary equipment for power tower maintenance, the hoisting box 1 is used to carry maintenance tools and personnel. As a working platform for maintenance personnel, it provides them with a relatively stable space, enabling them to have a safe and comfortable operating space when working at heights, facilitating various maintenance tasks. At the same time, the hoisting box 1 also serves as the installation foundation for other components, combining them into a whole device and ensuring the structural integrity of the entire auxiliary equipment.

[0029] The telescopic rod 2 is used to adjust the distance between the hoisting box 1 and the power tower body, so that the hoisting box 1 can adapt to the maintenance needs of different positions. At the same time, it can be flexibly adjusted according to the structural characteristics of the tower body, which enhances the adaptability of the equipment, meets the maintenance scenarios of power towers of different specifications, reduces maintenance difficulties caused by location restrictions, and improves the flexibility of maintenance work.

[0030] The locking assembly 3 is connected to the tower body of the power tower, which securely fixes the hoisting box 1 to the tower body, preventing the hoisting box 1 from shifting or shaking during operation. This provides a stable working platform for maintenance personnel, greatly reduces the safety risks of maintenance personnel working at height, ensures the personal safety of maintenance personnel, and improves the stability and reliability of maintenance operations.

[0031] Under the control of the drive component 5, the electromagnet 4 can be attracted to the tower body of the power transmission tower. The electromagnet 4 and the locking component 3 work together to further enhance the connection stability between the hoisting box 1 and the tower body. Even in severe weather conditions such as strong winds, the combined action of the electromagnet 4 and the locking component 3 can effectively prevent the hoisting box 1 from swaying, ensuring the safety of maintenance personnel working inside the hoisting box 1 and improving the equipment's performance in complex environments.

[0032] Specifically, the mounting housing 13 is used to protect the drive component 5 installed inside it, so that the drive component 5 is protected from the corrosion of the external environment. At the same time, it provides a stable mounting position for the drive component 5, which can extend the service life of the drive component 5 and ensure the normal operation of the drive component 5. This ensures that the electromagnet 4 can work stably and indirectly improves the reliability of the entire auxiliary equipment.

[0033] The driving component 5 serves as the power source for the operation of the electromagnet 4, driving the electromagnet 4 to approach or move away from the tower body, thereby enabling the electromagnet 4 to attract and separate from the tower body. The driving component 5 makes the attraction and separation operation of the electromagnet 4 more convenient and precise, allowing maintenance personnel to flexibly control the working state of the electromagnet 4 according to the actual operation situation, thus improving the ease of operation and work efficiency of the equipment.

[0034] The protective component 6 provides additional safety protection for maintenance personnel, preventing them from falling due to accidents (such as loss of balance, shaking of the hoisting box 1, etc.) during operation. This greatly reduces the safety risks for maintenance personnel when working at heights, allowing them to work with greater peace of mind, reducing psychological pressure caused by concerns about safety issues, and improving the safety and reliability of maintenance work.

[0035] The equipment is lifted to the location requiring maintenance on the power transmission tower using external lifting equipment such as a crane. The telescopic rod 2 on the lifting box 1 drives the locking assembly 3 to move to the corresponding position on the tower body, locking the locking assembly 3 to the tower body. The driving component 5 then drives the electromagnet 4 to approach and engage with the corresponding position on the tower body. The synergistic action of the locking assembly 3 and the electromagnet 4 significantly improves the connection stability between the lifting box 1 and the tower body, further enhancing the safety, stability, and efficiency of maintenance personnel performing high-altitude maintenance on power transmission towers. Even in severe weather conditions such as strong winds, the equipment effectively reduces the swaying of the lifting box 1, ensuring the personal safety of maintenance personnel and enabling them to accurately locate the maintenance area in a stable environment, efficiently completing the maintenance work. Simultaneously, the equipment's flexible adjustment function and good adaptability can meet the maintenance needs of different power transmission towers, reducing maintenance costs, ensuring the stable operation of power transmission towers, and thus guaranteeing the reliability of power supply.

[0036] The top of the hoisting container 1 is equipped with multiple lifting rings 12 for connecting steel wire ropes. The lifting rings 12 are key components connecting the hoisting container 1 to the steel wire ropes. Through the connection between the lifting rings 12 and the steel wire ropes, the hoisting container 1 is connected to the lifting equipment, enabling the hoisting container 1 to be raised, lowered, and moved. This allows the hoisting container 1 to smoothly reach various maintenance positions on the power transmission tower. This connection method is simple and reliable, facilitating quick installation and removal of the steel wire ropes in different working scenarios. Lifting rings 12 are installed at each corner of the top of the hoisting container 1. Multiple lifting rings 12 evenly distribute the weight of the hoisting container 1 during hoisting to each steel wire rope, avoiding excessive stress at a single point and reducing the risk of damage to the lifting rings 12, steel wire ropes, and the structure of the hoisting container 1 itself. Each lifting ring 12 shares a portion of the weight, improving the safety and reliability of the entire hoisting system and ensuring the safety of maintenance personnel and the normal operation of the equipment.

[0037] The size, shape, and structural design of the lifting ring 12 can be selected according to the actual application scenario, and the selected lifting ring 12 should facilitate the operator to connect and disconnect the wire rope to improve work efficiency.

[0038] A fixing plate 21 is installed at the end of the telescopic rod 2. A locking component 3 is installed on the other side of the fixing plate 21. The fixing plate 21 serves as an intermediate connecting component, providing a stable installation base for the locking component 3. The fixing plate 21 tightly connects the locking component 3 to the telescopic rod 2, ensuring that the locking component 3 can be stably fixed at the end of the telescopic rod 2 during operation. It also helps to distribute the force exerted by the locking component 3 on the telescopic rod 2, preventing the telescopic rod 2 from being damaged due to uneven force.

[0039] The locking assembly 3 includes a first locking member 31 and a second locking member 32. One end of the first locking member 31 and one end of the second locking member 32 are hinged together. The other end of the first locking member 31 and the other end of the second locking member 32 are connected to a locking bolt 33. A locking nut 34 is threaded onto the locking bolt 33. The first locking member 31 and the second locking member 32 together form the key part that directly contacts the tower body of the power transmission tower and realizes the locking function. The first locking member 31 and the second locking member 32 can rotate relative to each other through the hinged end, which is convenient to adapt to the tower body of power transmission towers of different shapes and sizes during installation, increasing the versatility of the equipment. The other end is connected by the locking bolt 33 and the locking nut 34. After the position is adjusted, the two can be tightly fixed to the tower body to realize a stable connection of the hoisting box 1, effectively preventing the hoisting box 1 from shaking or shifting during operation, and greatly improving the safety of maintenance personnel working at height.

[0040] Locking bolts 33 and locking nuts 34 are used to connect the first locking member 31 and the second locking member 32. The connection between the two is tightened and adjusted through threaded transmission. When it is necessary to fix the locking assembly 3 to the tower body, the locking nut 34 is rotated to move on the locking bolt 33, thereby adjusting the distance between the first locking member 31 and the second locking member 32 to adapt to the shape of the tower body and achieve the purpose of tightening. This greatly reduces the swaying risk of the hoisting box 1 when working at height, ensures the personal safety of maintenance personnel, enables maintenance personnel to work in a stable environment, improves the efficiency of the entire power tower maintenance work, and ensures the smooth progress of power tower maintenance work.

[0041] The first locking member 31 has a first connecting member 311 at its end, and the first connecting member 311 has a first threaded hole. The second locking member 32 has a second connecting member 321 at its end, and the second connecting member 321 has a second threaded hole. The locking bolt 33 passes through the first threaded hole and the second threaded hole in sequence and is threadedly connected to the locking nut 34 to connect the first locking member 31 and the second locking member 32. The first connecting member 311 serves to expand the connection structure, making the connection between the first locking member 31 and the locking bolt 33 more convenient and stable. The first threaded hole provides a precise installation position for the locking bolt 33. Through the threaded engagement, the accuracy and stability of the installation of the locking bolt 33 can be guaranteed, ensuring that the first locking member 31 can be tightly engaged with the locking bolt 33 during the tightening process, while limiting the displacement of the locking bolt 33 in this direction and ensuring the reliability of the connection.

[0042] The second connector 321, located at the end of the second locking member 32, also serves to strengthen the connection. It is a key component for connecting the second locking member 32 with the locking bolt 33. The second threaded hole and the first threaded hole cooperate with each other, forming a threaded connection with the locking bolt 33 when the locking bolt 33 passes through, further fixing the position of the locking bolt 33. At the same time, it ensures that the second locking member 32 and the first locking member 31 are tightly connected together through the locking bolt 33 and the locking nut 34, enhancing the overall connection strength and ensuring that the connection between the hoisting box 1 and the power tower remains stable under various working conditions, reducing the safety risks of high-altitude operations.

[0043] The locking nut 34 is threadedly connected to the locking bolt 33. During the tightening process, the axial force generated pulls the first locking member 31 and the second locking member 32 tightly together, achieving a tight connection between them. The tightness of the connection can be controlled by adjusting the tightening degree, thus achieving a reliable connection between the first locking member 31 and the second locking member 32. The tightness of the connection can be flexibly adjusted according to the actual situation of the power tower body, ensuring that the locking assembly 3 fits tightly with the tower, effectively preventing the hoisting box 1 from shaking, improving the stability and safety of the auxiliary equipment for power tower maintenance during use, and ensuring the smooth progress of maintenance work.

[0044] A spring 35 is fitted onto the locking bolt 33, located between the locking bolt 33 and the first connecting member 311. When the hoisting box 1 is subjected to external force and shakes, the spring 35 can buffer the instantaneous tensile or compressive changes on the locking bolt 33, preventing damage to the locking bolt 33 due to sudden force. It also reduces the impact on the first locking member 31, the second locking member 32, and the tower body. In other words, during the maintenance of power towers, external environmental factors (such as strong winds and equipment vibrations) may cause the hoisting box 1 and connecting components to shake and vibrate. The spring 35, located between the locking bolt 33 and the first connecting member 311, absorbs the impact force from these vibrations and shaking through its own elastic deformation, making the hoisting box 1 more stable and providing a safer and more reliable working environment for maintenance personnel.

[0045] Furthermore, prolonged use of the equipment and external factors may cause the locking bolts 33 and nuts to loosen. The spring 35 is under a certain compression during installation and has a tendency to return to its original state. When the locking bolts 33 and nuts become loose, the spring 35 will apply a force to push the first connecting piece 311, causing the locking bolts 33 to maintain a certain tightening force. This compensates for the reduced clamping force due to loosening to a certain extent, preventing the connection between the locking assembly 3 and the tower from completely failing. This improves the reliability of the connection, reduces the risk of the hoisting box 1 shaking, shifting, or even falling off due to loose connection, ensures the safety of maintenance personnel, reduces the need for frequent re-tightening due to loose connection, and improves the efficiency of maintenance work.

[0046] refer to Figure 1 and Figure 2 The hoisting box 1 has a through slot 11 on its side for the electromagnet 4 to pass through. The mounting housing 13 is installed on one side of the through slot 11. The fixed end of the driving component 5 is fixedly mounted on the mounting housing 13, and the output end of the driving component 5 is connected to the electromagnet 4. The through slot 11 provides a moving channel for the electromagnet 4, allowing it to pass through the side of the hoisting box 1 and approach the tower body of the power transmission tower, achieving a magnetic connection with the tower body. Simultaneously, the through slot 11 limits the movement trajectory of the electromagnet 4, ensuring that it accurately approaches and leaves the tower body under the action of the driving component 5, preventing the electromagnet 4 from deviating during movement and affecting the attraction effect with the tower body. This ensures the normal operation of the electromagnet 4 and enhances the stability of the connection between the hoisting box 1 and the tower body. The through slot 11 also facilitates the installation and maintenance of the electromagnet 4; when the electromagnet 4 malfunctions, it is easy to repair or replace it through the through slot 11.

[0047] The mounting housing 13 serves as the mounting carrier for the drive component 5, providing a stable mounting position for the drive component 5 and keeping it fixed during operation to prevent displacement due to vibration or other factors. Simultaneously, it protects the drive component 5 from external dust, moisture, and other impurities that could affect its performance and lifespan.

[0048] The driving component 5 serves as the power source, providing driving force for the movement of the electromagnet 4. This driving component 5 can be a telescopic cylinder; its extension and retraction cause the electromagnet 4 to move closer to or further away from the tower body, achieving the attraction and separation of the electromagnet 4 from the tower body. Precise control of the driving component 5 allows the electromagnet 4 to adhere tightly to the tower body at the appropriate time, enhancing connection stability, and also enables easy separation when needed, facilitating the movement and adjustment of the hoisting box 1. In windy weather or complex maintenance environments, maintenance personnel can adjust the state of the electromagnet 4 in a timely manner according to the actual situation, ensuring a safe and reliable connection between the hoisting box 1 and the tower body, and guaranteeing the smooth progress of maintenance work.

[0049] In the maintenance of power transmission towers, the movement of electromagnet 4 is controlled by drive component 5, which not only enhances the connection strength between hoisting box 1 and tower body and effectively reduces the swaying of hoisting box 1 in windy weather, ensuring the safety of maintenance personnel, but also improves the efficiency of maintenance work.

[0050] The protective component 6 includes a fixing member 61 and a protective garment 62. The fixing member 61 is installed on both sides inside the hoisting box 1. The fixing member 61 is connected to a connecting rope 63. The other end of the multiple connecting ropes 63 is connected to the protective garment 62. The protective garment 62 is connected to a fall arresting rope 64. The end of the fall arresting rope 64 is connected to an anti-detachment hook 65 for connecting to the tower body. The fixing member 61 serves as the connection hub, providing a fixing point for the connecting ropes 63. The fixing member 61 securely connects the connecting ropes 63 to the hoisting box 1, ensuring that the connecting ropes 63 can function stably, while dispersing the tension on the connecting ropes 63 and avoiding concentrated force that could damage the hoisting box 1.

[0051] The connecting rope 63 connects the fixing component 61 and the protective clothing 62, integrating the protective clothing 62 with the hoisting box 1 into a single unit. When maintenance personnel move inside the hoisting box 1, the connecting rope 63 restricts the range of motion of the protective clothing 62. In the event of accidental loss of balance or swaying of the hoisting box 1, the rope 63 pulls the protective clothing 62 to prevent the maintenance personnel from falling from the hoisting box 1, thus providing basic safety assurance for the maintenance personnel.

[0052] The protective suit 62 is worn by the maintenance personnel and serves as a protective component that comes into direct contact with them. It integrates the connection point of the connecting rope 63 and the fall arrestor rope 64. Connected to the hoisting box 1 via the connecting rope 63, it bears the tension transmitted by the connecting rope 63, protecting the maintenance personnel's body and preventing injury from collisions or falls.

[0053] One end of the fall arrestor rope 64 is connected to the protective clothing 62, and the other end is connected to the anti-detachment hook 65. In the event that maintenance personnel accidentally fall from the hoisting box 1, it serves as a backup safety line. It can extend the connection distance between the protective clothing 62 and the tower body. When the connecting rope 63 cannot completely prevent the maintenance personnel from falling, it can pull the maintenance personnel in time to prevent them from falling directly to the ground. This greatly enhances the safety of the protective component 6, provides additional safety protection for maintenance personnel, and can save the lives of maintenance personnel at critical moments, reducing the serious consequences of high-altitude fall accidents.

[0054] The anti-detachment hook 65 connects the fall arrest rope 64 to the tower body of the power tower, fixing the fall arrest rope 64 to the tower body. This ensures that the fall arrest rope 64 can effectively function when maintenance personnel fall, preventing accidental detachment during use, guaranteeing the reliability of the connection, and making maintenance personnel more at ease when working at heights.

[0055] A storage box 7 is provided inside the hoisting box 1. Multiple partitions are installed inside the storage box 7 at intervals. A cover plate 71 is hinged to the top of the storage box 7. The storage box 7 can provide storage space for storing various tools, parts and other related items used in the maintenance of power towers. These items are stored together to avoid being placed randomly in the hoisting box 1, and to prevent items from being scattered and lost or damaged when the hoisting box 1 shakes. It also makes it convenient for maintenance personnel to quickly find the items they need.

[0056] The partitions divide the interior space of storage box 7 into multiple independent small areas. Each small area can be used to store different tools or parts, enabling categorized storage and management of items. This further improves the orderliness of storage, allowing maintenance personnel to quickly find the required items according to the categories, saving search time and improving work efficiency. At the same time, the partitions also play a certain role in fixing items, preventing them from colliding or being squeezed together inside storage box 7, and protecting the integrity of the items.

[0057] The hinged cover 71 at the top of the storage box 7 can cover the opening of the storage box 7, which can protect the items inside the storage box 7. The cover 71 can prevent dust, moisture and other impurities from entering the storage box 7, and prevent the items from getting damp, rusting or contaminated.

[0058] The implementation process of an auxiliary device for power tower maintenance according to an embodiment of this application is as follows:

[0059] On the ground, sort and place the maintenance tools and spare parts into the storage box 7, close the cover 71, check that the protective components 6 are intact, connect the anti-detachment hook 65 to the tower structure at a suitable location on the power tower, and ensure that the fall arrest rope 64 is securely connected. At the same time, check that the telescopic pole 2, locking components 3, electromagnet 4, drive components 5, and other components are working properly.

[0060] The hoisting box 1 is lifted to the vicinity of the maintenance position of the power tower using a steel wire rope. The telescopic rod 2 is extended or retracted to bring the hoisting box 1 close to the tower body. The first locking part 31 and the second locking part 32 of the locking assembly 3 are opened and placed on the appropriate position on the tower body. Then, the locking bolts 33 and locking nuts 34 are used to tighten them to ensure that the hoisting box 1 is initially fixed. The drive component 5 is activated to bring the electromagnet 4 close to the tower body and attract it to the tower body to further stabilize the hoisting box 1.

[0061] When maintenance personnel put on protective clothing 62 and connect the connecting rope 63 to the protective clothing 62, they can retrieve tools and parts from the storage box 7 as needed when carrying out maintenance work inside the hoisting box 1. In case of severe weather such as strong winds, the electromagnet 4 and the locking assembly 3 work together to reduce the swaying of the hoisting box 1 and ensure the safety of maintenance personnel and the stability of the operation.

[0062] After maintenance is completed, first operate the drive unit 5 to separate the electromagnet 4 from the tower body. Then, loosen the locking bolts 33 and locking nuts 34 of the locking assembly 3, remove the first locking component 31 and the second locking component 32 from the tower body, retract the telescopic rod 2, and hoist the hoisting box 1 to the ground using a wire rope. Take out the maintenance tools and parts from the storage box 7 and organize them. Check the condition of each component of the equipment to prepare for the next use.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
