Description

Technical Field

[0001] This invention belongs to the field of power maintenance technology, and more specifically, relates to a safe climbing tool for power poles during power maintenance. Background Technology

[0002] Power lines transmit electrical energy between power plants, substations, and power users, while power poles are electrical devices used to erect and fix power lines, thereby transmitting and distributing electrical energy. When power lines are damaged and power is lost, maintenance personnel usually need to climb to the top of the power poles to repair the power lines.

[0003] Existing methods for climbing utility poles for maintenance have the following disadvantages:

[0004] Most existing climbing tools are either ladder climbing or foot-clamping climbing. Ladder climbing involves placing the ladder against the utility pole, allowing the user to climb to a higher position for maintenance. Foot-clamping climbing involves using foot clamps to attach tools and climb the pole. However, when using either of these methods, if the user forgets to bring some tools or accessories, or if tools or accessories are accidentally dropped, workers may need to climb down again to retrieve them before climbing back up to continue working. Alternatively, other workers on the ground may need to climb up to pass the tools or accessories. This is labor-intensive, inefficient, and poses certain dangers, making it quite inconvenient.

[0005] The existing climbing tools do not have storage mechanisms, requiring users to carry a lot of tools during maintenance. This makes it difficult for maintenance personnel to climb up the pole and climb down after maintenance, and the heavy load during maintenance may affect the efficiency of maintenance and waste manpower.

[0006] The existing climbing equipment does not have a collection mechanism. After completing the maintenance of the utility pole, there may be some maintenance waste. If it is thrown directly from the height, it will need to be cleaned and collected later, which is inconvenient. Moreover, throwing from a height is dangerous. If the staff carries it down, they will also need to carry the waste with them when they climb down, which will affect the climbing.

[0007] Existing ladder-style climbing tools do not have fixed devices. On uneven ground, when they are pressed against the ground, they may be unstable and uneven in force during climbing, which may cause them to tip over, posing a certain safety hazard.

[0008] Existing foot-covered climbing tools rely entirely on the friction between the foot cover and the pole, as well as the climber's own weight, for support. These foot covers experience significant wear and tear over long-term use and require frequent replacement. Otherwise, the climbing tool may become unstable and pose a certain danger.

[0009] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a safe climbing tool for power pole maintenance, in order to achieve a more practical purpose. Summary of the Invention

At least two second mounting grooves are opened through the side end of the C-shaped plate, and the same second threaded rod is rotatably installed on the inner side wall of the two second mounting grooves. Second mounting grooves are opened through the side ends of the C-shaped plate. At least two limiting circular grooves are opened through the side ends of the C-shaped plate. A pull plate is provided on one side of the C-shaped plate, and two limiting posts are fixedly installed on the side end of the pull plate. A spring is fixedly installed between the pull plate and the second threaded rod. A second telescopic rod is also fixedly installed between the pull plate and the second threaded rod. The second telescopic rod is located on the inner wall of the spring. A third rectangular groove is opened through the side end of the lifting plate.

[0013] Preferably, a sliding plate is fixedly installed on the side end of each climbing board, two cylindrical sliding grooves are opened through the upper end of each sliding plate, and a cylindrical sliding rod is fixedly installed on the side end of each sliding plate.

[0014] Preferably, at least two inclined grooves are provided through the side end of the rectangular plate, each inclined groove is inclined, and the included angle between each inclined groove is 30 degrees. A connecting rod is fixedly installed at the lower end of the rectangular plate, and a second threaded groove is provided through the side end of the connecting rod. The second threaded rod is rotatably installed on the inner side wall of the second threaded groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, a motor, a lifting plate, and a storage box work together. When a user forgets to bring some tools or accessories, or when tools or accessories are accidentally dropped, the user can have a worker on the ground place the workpiece on the storage box. The motor then drives the gears to climb upwards on the gear column, thus achieving tool transfer. This eliminates the need for workers to climb down to retrieve the tools or for workers on the ground to climb up to pass them. It saves manpower, is highly safe, has high transfer efficiency, allows for reciprocating movement, facilitates multiple transfers, and is convenient to use.

[0017] In this invention, by providing a lifting plate and a storage box, the storage box on the lifting plate can also serve as a temporary storage box for tools or a transport box for miscellaneous items. When users are performing maintenance, it is inconvenient to carry a large number of tools. Users can place some tools in the storage box, so they do not need to carry a lot of weight when climbing upwards for maintenance, thus ensuring safety.

[0018] In this invention, the storage box is designed to handle the waste that may accumulate after maintenance. Directly throwing the waste away would require further cleaning and collection, and throwing it from a height poses a certain risk. If the waste is carried by staff, it may be inconvenient for them to climb down. By placing the maintenance waste in the storage box and transporting it down, it is easier to collect and process it centrally, making it safer and more convenient to collect, and it will not affect the user's ability to climb down from the device.

[0019] In this invention, by using a conical needle and an arc-shaped plate in combination, when fixing the L-shaped base, the conical needle can be placed directly on cement or asphalt ground, or inserted into uneven muddy ground, and is fixed stably. It can be used in different environmental ground conditions. The first threaded rod can be rotated so that the arc-shaped plate and L-shaped bracket can clamp the pole, ensuring that the device will not shake or tip over due to uneven force during climbing and maintenance, thus ensuring the safety of the staff.

[0020] In this invention, by providing easily adjustable climbing boards, users can adjust the spacing between each climbing board according to their own climbing habits before climbing. The rectangular boards are moved by rotating the second threaded rod. The adjustment is simple and easy to make in coordination with different maintenance personnel, ensuring convenient climbing and high flexibility.

[0021] In this invention, by providing a pull plate, a limiting post, a C-shaped plate, and a limiting groove in combination, the limiting post on the pull plate can be inserted into the inner wall of the limiting groove to limit the rectangular plate, thereby limiting and fixing each climbing plate, ensuring the stability of each climbing plate when the repairman is climbing, avoiding instability of the climbing plate caused by the second threaded rod possibly slipping, and ensuring climbing safety.

[0022] In this invention, by using a cylinder and an L-shaped bracket in combination, the device can be finely adjusted. The user can start the cylinder through an infrared remote control device to extend or retract the cylinder, thereby raising or lowering the L-shaped bracket. This ensures that the height of the top of the L-shaped bracket matches the height of the pole, facilitating adjustment and maintenance and improving the adaptability of the device.

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Example

[0033] Please see Figures 1 to 8 This invention provides a technical solution including an L-shaped base 1, a conveying mechanism for easy tool carrying, a support mechanism for easy climbing, and a fixing mechanism for easy fixation. The conveying mechanism includes an L-shaped bracket 2, a lifting plate 5, and a motor 6. Two cylinders 12 are fixedly installed between the L-shaped bracket 2 and the L-shaped base 1. When the user climbs to a high point of the device, if the height of the utility pole is still too high or the position of the utility pole is too low compared to the height of the device, the user can make fine adjustments to the device. The user can activate the cylinders 12 through an infrared remote control device to extend or retract the cylinders 12, thereby raising or lowering the L-shaped bracket 2 so that the height of the top of the L-shaped bracket 2 matches the height of the utility pole, facilitating adjustment and maintenance and improving the adaptability of the device.

[0034] Two second rectangular slots 25 are provided on the side end of the L-shaped bracket 2. Two movable plates 52 are fixedly installed on the side end of the lifting plate 5. Both movable plates 52 are slidably installed on the inner side wall of the two second rectangular slots 25. A storage box 51 is fixedly installed on the upper end of the lifting plate 5. The support mechanism includes a mounting plate 33, a C-shaped plate 4, a rectangular plate 8, and a climbing plate 7. The mounting plate 33 is fixedly installed on the side end of the L-shaped bracket 2. One side of the C-shaped plate 4 is fixedly installed on the side end of the mounting plate 33, and the other side of the C-shaped plate 4 is fixedly installed on the inner side wall of the L-shaped bracket 2. Two third telescopic rods 82 are fixedly installed between the rectangular plate 8 and the inner side wall of the L-shaped bracket 2. The fixing mechanism includes an arc-shaped plate 3 and a conical pin 11. The number of conical pins 11 is... There are at least two conical pins 11, each fixedly installed at the lower end of the L-shaped base 1. Before maintenance, the user can fix the device. At least two conical pins 11 are fixedly installed under the L-shaped base 1. When facing some uneven muddy ground, the user can directly insert the conical pins 11 into the ground to fix the L-shaped base 1. As shown in the figure, the user can clamp the pole between the arc plate 3 and the L-shaped bracket 2. The user can rotate the first threaded rod 32. The first threaded rod 32 rotates in the first threaded groove 31, which can drive the arc plate 3 to move. The arc plate 3 moves and stretches the first telescopic rod 28. When the arc plate 3 cooperates with the L-shaped bracket 2 to clamp the pole, the device is fixed.

[0035] The arc-shaped plate 3 is located on the inner wall of the L-shaped bracket 2. A first rectangular groove 21 is opened through the side end of the L-shaped bracket 2. Two fixing posts 22 are fixedly installed on the inner wall of the first rectangular groove 21. An annular groove 23 is opened on the side end of the first rectangular groove 21. At least two toothed posts 24 are fixedly installed on the side end of the L-shaped bracket 2. A side rod 26 is fixedly installed on the side end of the inner wall of the L-shaped bracket 2. A first mounting groove 27 is opened through the side end of the side rod 26. Two first telescopic rods 28 are fixedly installed between the arc-shaped plate 3 and the side rod 26. A first threaded rod 32 is rotatably installed on the inner wall of the first mounting groove 27. A first threaded groove 31 is opened through the side end of the arc-shaped plate 3. The first threaded rod 32 is rotatably installed on the inner wall of the first threaded groove 31. At least two second mounting grooves 42 are opened through the side end of the C-shaped plate 4. The same second... The threaded rod 49 and the C-shaped plate 4 are provided with second mounting grooves 42 through both ends. The side end of the C-shaped plate 4 is provided with at least two limiting circular grooves 41. A pull plate 45 is provided on one side of the C-shaped plate 4. Two limiting posts 48 are fixedly installed on the side end of the pull plate 45. A spring 46 is fixedly installed between the pull plate 45 and the second threaded rod 49. A second telescopic rod 47 is also fixedly installed between the pull plate 45 and the second threaded rod 49. The second telescopic rod 47 is located on the inner wall of the spring 46. The user can adjust the spacing between each climbing board 7 according to their height and climbing habits. The user can pull the pull plate 45. The movement of the pull plate 45 drives the two limiting posts 48 to move. After the limiting posts 48 move away from the inner wall of the limiting circular grooves 41, the user can rotate the pull plate 45. The rotation of the pull plate 45 drives the second threaded rod 49 to rotate in the two second mounting grooves 42 through the second telescopic rod 47.

[0036] The lifting plate 5 has a third rectangular groove 53 through its side end, and two fourth rectangular grooves 54 are provided on the side end of the lifting plate 5. The lifting plate 5 moves upward, causing the movable plate 52 to move upward in the second rectangular groove 25. The lifting plate 5 causes the storage box 51 to move upward. When the storage box 51 moves to the upper end of the L-shaped bracket 2, the user can turn off the motor 6. After taking out the tools and accessories in the storage box 51, the user can drive the motor 6 to start again. The motor 6 starts to rotate, causing the gear 63 on the rotating rod 62 to continue to rotate along the tooth column 24. At this time, the gear 63 moves to the other side and climbs down along the tooth column 24, thereby causing the storage box 51 to move downward.

[0037] Two insert plates 61 are fixedly installed on the side end of the motor 6. Both insert plates 61 slide on the inner wall of the fourth rectangular slide groove 54. A rotating rod 62 is fixedly installed on the output end of the motor 6. The rotating rod 62 slides through the inner wall of the third rectangular slide groove 53. A gear 63 is fixedly installed on the circumferential end of the rotating rod 62. The gear 63 meshes with each toothed column 24. A cylinder 64 is fixedly installed on the side end of the rotating rod 62. The cylinder 64 slides on the inner wall of the annular groove 23. When the user performs maintenance, some tools and accessories... If the tool is forgotten or accidentally dropped, the user can have a ground-based worker place the workpiece on the storage box 51. The infrared remote control device drives the motor 6, which in turn drives the rotating rod 62 to rotate. The rotating rod 62 then drives the gear 63 to rotate. The gear 63 rotates and climbs upward along each toothed column 24. The upward movement of the gear 63 drives the rotating rod 62 to move upward. The upward movement of the rotating rod 62 drives the insert plate 61 to move upward through the motor 6. The upward movement of the insert plate 61 then drives the lifting plate 5 to move upward.

[0038] There are at least two climbing boards 7. Each climbing board 7 has a climbing groove 71 extending through its upper end. Each climbing board 7 has a triangular support plate 75 fixedly installed at its lower end. Each climbing board 7 has a sliding plate 72 fixedly installed at its side end. Each sliding plate 72 has two cylindrical sliding grooves 73 extending through its upper end. Each sliding plate 72 has a cylindrical sliding rod 74 fixedly installed at its side end. The second threaded rod 49 rotates through the second threaded groove 83, causing the connecting rod 84 to slide. The movement of the connecting rod 84 causes the rectangular plate 8 to move. When the rectangular plate 8 moves, the third extension... As the retractor 82 shortens, the rectangular plate 8 moves, causing each cylindrical slide bar 74 to gradually move away from each other via the inclined groove 81. This movement of each cylindrical slide bar 74 causes each sliding plate 72 to move away from each other, which in turn causes each climbing plate 7 to move away from each other. After adjusting the distance between each climbing plate 7 to a suitable height, the user can stop rotating the pull plate 45 and release it. At this time, the spring 46 rebounds, causing the limiting post 48 on the pull plate 45 to re-insert into the inner wall of the limiting circular groove 41, thus limiting the second threaded rod 49.

[0039] At least two inclined grooves 81 are provided through the side end of the rectangular plate 8. Each inclined groove 81 is inclined and the included angle between each inclined groove 81 is 30 degrees. A connecting rod 84 is fixedly installed at the lower end of the rectangular plate 8. A second threaded groove 83 is provided through the side end of the connecting rod 84. The second threaded rod 49 is threaded and rotatably installed on the inner side wall of the second threaded groove 83.

[0040] Working principle:

[0041] The first step involves a transformer between two utility poles. During maintenance, workers need to climb to a height. When repairing the transformer, the user can insert the conical needle 11 on the L-shaped base 1 into the ground, and clamp the L-shaped bracket 2 and the arc plate 3 onto the utility pole. Rotating the first threaded rod 32 allows the arc plate 3 and the L-shaped bracket 2 to clamp the utility pole, thus fixing the device. After fixing, the second threaded rod 49 can be rotated to move the rectangular plate 8, thereby adjusting the opening of each climbing board 7 to a suitable distance for the user to climb. The user can climb the climbing board 7 to a high position on the utility pole to carry out maintenance work. If tools or parts are forgotten or fall due to improper operation during maintenance, the workers on the ground can place the parts and tools in the storage box 51. The infrared drive device drives the motor 6, which rotates to drive the gear 63 to climb along the tooth column 24, thereby raising the storage box 51 on the lifting plate 5 to a high position for the transfer of tools.

[0042] The second step is for the user to fix the device before maintenance. At least two conical pins 11 are fixedly installed under the L-shaped base 1. When facing some uneven muddy ground, the user can directly insert the conical pins 11 into the ground to fix the L-shaped base 1. As shown in the figure, the user can clamp the pole between the arc plate 3 and the L-shaped bracket 2. The user can rotate the first threaded rod 32. The first threaded rod 32 rotates in the first threaded groove 31, which can drive the arc plate 3 to move. The arc plate 3 moves and stretches the first telescopic rod 28. When the arc plate 3 and the L-shaped bracket 2 clamp the pole, the device is fixed.

[0043] This device, through the combination of a conical needle 11 and an arc-shaped plate 3, allows the conical needle 11 to be placed directly on cement or asphalt surfaces or inserted into uneven muddy ground when fixing the L-shaped base 1. It is stable and can be used in different environments. The first threaded rod 32 can be rotated to clamp the pole with the arc-shaped plate 3 and the L-shaped bracket 2, ensuring that the device will not shake or tip over due to uneven force during climbing and maintenance, thus ensuring the safety of the staff.

[0044] Thirdly, after fixing the device, the user can adjust the spacing between each climbing board 7 according to their height and climbing habits. The user can pull the pull plate 45, which moves the two limiting posts 48. After the limiting posts 48 move away from the inner wall of the limiting groove 41, the user can rotate the pull plate 45. The rotation of the pull plate 45 drives the second threaded rod 49 to rotate in the two second mounting grooves 42 through the second telescopic rod 47. The rotation of the second threaded rod 49 drives the connecting rod 84 to slide through the second threaded groove 83. The movement of the connecting rod 84 drives the rectangular plate 8 to move. At this time, the third telescopic... As the rod 82 shortens, the rectangular plate 8 moves, causing each cylindrical slide bar 74 to gradually move away from each other via the inclined groove 81. This movement of each cylindrical slide bar 74 causes each sliding plate 72 to move away from each other, which in turn causes each climbing plate 7 to move away from each other. After adjusting the distance between each climbing plate 7 to a suitable height, the user can stop rotating the pull plate 45 and release it. At this time, the spring 46 rebounds, causing the limiting post 48 on the pull plate 45 to re-insert into the inner wall of the limiting circular groove 41, limiting the second threaded rod 49 and ensuring the stability of the rectangular plate 8 and each climbing plate 7 during climbing.

[0045] This device features adjustable climbing boards 7, allowing users to adjust the spacing between each board 7 according to their climbing habits before climbing. The rectangular board 8 can be moved by rotating the second threaded rod 49. The adjustment is simple and easy to make with different maintenance personnel, ensuring convenient climbing and high flexibility.

[0046] This device, through the cooperation of a pull plate 45, a limiting post 48, a C-shaped plate 4, and a limiting groove 41, allows the limiting post 48 on the pull plate 45 to be inserted into the inner wall of the limiting groove 41, thereby limiting the rectangular plate 8 and fixing each climbing plate 7. This ensures the stability of each climbing plate 7 when the maintenance personnel climb, avoids the instability of the climbing plate 7 caused by the second threaded rod 49 possibly becoming loose, and ensures climbing safety.

[0047] Fourth, when the user climbs to the height of the device, if the height of the utility pole is still too high, or the position of the utility pole is too low for the device, the user can make fine adjustments to the device. The user can activate the cylinder 12 through the infrared remote control device to extend or retract the cylinder 12, thereby raising or lowering the L-shaped bracket 2 so that the height of the top of the L-shaped bracket 2 matches the height of the utility pole, making it easier to adjust and maintain, and improving the adaptability of the device.

[0048] Fifthly, when the user forgets to bring some tools and accessories during maintenance, or if tools and accessories are accidentally dropped, the user can have a ground-based worker place the workpiece on the storage box 51. The infrared remote control device then drives the motor 6. The motor 6 starts, causing the rotating rod 62 to rotate. The rotating rod 62 rotates, causing the gear 63 to rotate. The gear 63 rotates and climbs upwards along each toothed column 24. The upward movement of the gear 63 causes the rotating rod 62 to move upwards. The upward movement of the rotating rod 62, through the motor 6, causes the insertion plate 61 to move upwards. The upward movement of the insertion plate 61 then drives the lifting mechanism... Lifting plate 5 moves upward, which in turn drives movable plate 52 to move upward within the second rectangular groove 25. Lifting plate 5 drives storage box 51 to move upward. When storage box 51 moves to the upper end of L-shaped bracket 2, the user can turn off motor 6. After retrieving the tools and accessories from storage box 51, the user can drive motor 6 to start again. The motor 6 starts rotating, which drives gear 63 on rotating rod 62 to continue rotating along gear column 24. At this time, gear 63 moves to the other side and climbs down along gear column 24, thereby driving storage box 51 to move downward.

[0049] This device, through the coordinated arrangement of a motor 6, a lifting plate 5, and a storage box 51, allows for the transfer of tools when a user forgets to bring some tools or accessories, or when tools or accessories are accidentally dropped. The user can have a worker on the ground place the workpiece on the storage box 51, which in turn drives the motor 6 to move the gear 63 upward on the gear column 24. This eliminates the need for workers to climb down to retrieve the tools or for workers on the ground to climb up to pass them. It saves manpower, is highly safe, has high transfer efficiency, can move back and forth, facilitates multiple transfers, and is easy to use.

[0050] This device is equipped with a lifting plate 5 and a storage box 51. The storage box 51 on the lifting plate 5 can also be used as a temporary storage box for tools or a transport box for miscellaneous items. When the user is performing maintenance, it is inconvenient to carry a lot of tools. The user can put some tools in the storage box 51, so that the user does not need to carry a lot of weight when climbing upwards for maintenance, thus ensuring safety.

[0051] The storage box 51 on this device is designed to prevent the accumulation of waste after maintenance. Directly throwing the waste would require further cleaning and collection, and throwing it from a height poses a certain risk. If it is carried by staff, it may be inconvenient for them to climb down. By placing the maintenance waste in the storage box 51 and transmitting it down, it is easier to collect and process in a centralized manner, making it safer and more convenient to collect, and it will not affect the user's ability to climb down from the device.

[0052] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
