Description

Technical Field

[0001] This invention relates to the field of power transmission facilities, and more particularly to power transmission towers that are easy to climb. Background Technology

[0002] A power transmission tower is a tower-shaped structure used for power transmission. It is usually a tall metal building with a hollow structure. It is mainly used to suspend and support power conductors, communication lines or other power installations, so that the power conductors, communication lines or other power installations maintain a safe distance from the ground or objects they cross.

[0003] A power transmission tower consists of three main parts from top to bottom: the tower head, the tower legs, and the tower body. The tower legs are in direct contact with the installation surface of the power transmission tower and are positioned with the contact surface through a concrete platform or fixed anchor bolts. They are mainly used to support the tower body and the tower head. The tower head is located at the upper end and is used to tension and support the conductors or communication lines. The tower body is the part between the tower head and the tower legs and mainly plays a role in resisting wind and bending. In order to facilitate the climbing of operators, ladders are also provided along the length of the tower body for operators to hold on to and step on.

[0004] In response to the aforementioned technologies, in order to reduce unauthorized personnel from climbing power transmission towers, there is usually a gap of three meters or more between the lower end of the ladder and the installation plane of the tower leg. When operators need to climb power transmission towers, they need to carry a mobile ladder to connect with the ladder. The mobile ladder is heavy and inconvenient to carry, making it inconvenient for operators to use the ladder. Summary of the Invention

[0005] To improve the convenience for operators climbing ladders on power transmission towers, this application provides power transmission towers that are easy to climb.

[0006] This application provides an easily climbable power transmission tower, employing the following technical solution: An easy-to-climb power transmission tower includes a tower body. Several tower legs are fixedly connected to the lower end of the tower body along its side. A ladder is provided along the length of any side of the tower body. Climbing components are provided on the tower legs located on the same side as the ladders. Each climbing component includes a support part and a movable rod. The support part is fixedly connected to the tower leg and parallel to it. A movement track is provided between the movable rod and the support part. The movable rod moves along the movement track towards or away from the tower body. Several foot pedals are provided on both sides of the movable rod along its length. Multiple sets of linkage components are provided between the movable rod and the foot pedals to drive the foot pedals to rotate. The movable rod has several openings adapted to the foot pedals. When the movable rod moves towards the tower body along the movement track, the linkage components drive the foot pedals to move into the openings, so that the foot pedals are located within the openings and parallel to the movable rods. When the movable rod moves away from the tower body along the movement track, the linkage components drive the foot pedals out of the openings and perpendicular to the movable rods. A positioning component is provided between the support part and the movable rod for locking and positioning the movable rod.

[0007] By adopting the above technical solution, four sets of tower legs work together to support the tower body. In the initial state, the moving rod is in contact with the support and is located close to the tower body. All the step bars are located in their respective openings. At this time, the support uses a positioning component to position the moving rod, reducing the probability of unauthorized personnel using the climbing mechanism. When the operator needs to climb the power tower, the positioning component is unlocked, and the moving rod is moved away from the tower body along the moving trajectory. At this time, the linkage component moves the corresponding step bars out of the openings. When the moving rod is located away from the tower body and is in contact with the support again, all the step bars are set perpendicular to the moving rod, and the step bars and the ladder are on the same side, making it convenient for the operator to climb the ladder along all the step bars. When the step bar needs to be retracted, the operator moves the movable bar along the movement trajectory toward the tower body, so that the connecting component moves the step bar into the corresponding opening. The positioning component then positions the movable bar, thus fixing it in place. By moving the movable bar along the movement trajectory, the step bar can be released and retracted. When climbing the power tower, the operator does not need to carry a movable ladder, which improves the convenience of climbing the power tower.

[0008] Optionally, the linkage assembly includes a connecting rod, a rotating disk, a sliding plate, and two sets of top rods. The connecting rod is located between the moving rod and the support. All connecting rods in the linkage assembly are parallel to each other. The end of the moving rod near the support has a vertical through groove. The rotating disk is located in the through groove and is rotatably connected to the connecting rod. One end of the connecting rod is fixedly connected to the rotating disk, and the other end is hinged to the support. The support has several placement grooves along its length that are adapted to the connecting rod. When the moving rod and the connecting rod are in contact, the connecting rod is located in the placement groove. The sliding plate is slidably connected to the moving rod along the length of the through groove. A rack is fixedly connected along the length of the sliding plate on the side near the support. A toothed block that meshes with the rack is fixedly connected along the circumferential direction to the rotating disk. The two sets of top rods are located on both sides of the sliding plate, and one end of the top rod is hinged to the sliding plate, and the other end is hinged to the pedal rod.

[0009] By adopting the above technical solution, when the moving rod is in contact with the support, the connecting rod is located in the placement groove. The placement groove is used to store the connecting rod. When the connecting rod moves along the moving trajectory, the rotating disk drives the connecting rod to swing. At the same time, the rotating disk rotates, and then the sliding plate slides along the length of the through groove through the meshing action of the tooth block and the rack. When the sliding plate slides, the corresponding pedal rod is rotated through two sets of top rods, thereby realizing the storage and release of the pedal rod.

[0010] Optionally, the positioning component includes a positioning block, a rotating part, and an unlocking rod. The positioning block is located at the lower end of the moving rod and is slidably connected to it along the length of the support part. An insert block is fixedly connected to the upper end of the positioning block. A slot adapted to the insert block is provided at the lower end of the moving rod. The rotating part passes through the positioning block and is rotatably connected to it. A positioning groove is provided on the outer circumference of the rotating part. A moving groove adapted to the positioning groove is provided on the positioning block. A locking block is slidably connected to the positioning block along the length of the moving groove. An elastic element is provided between the locking block and the positioning groove. When the moving groove and the positioning groove are aligned, the elastic element... A rotating part has a tendency to move the locking block towards the positioning groove. The rotating part has a through hole that matches the unlocking rod along the circumference, and a rotating groove that connects the through hole and the positioning groove. The rotating part also has a clearance groove that is parallel to the through hole and connects with the rotating groove. The unlocking rod is fixedly connected to the unlocking block. When the end of the unlocking block away from the unlocking rod abuts against the lower end of the locking block, the locking block is located outside the positioning groove. A positioning hook is fixedly connected to the side of the rotating part away from the positioning groove. The support part has a fixing groove that matches the positioning hook. When the positioning hook is inserted into the fixing groove, the insert and the slot cooperate.

[0011] By adopting the above technical solution, in the initial state, the positioning hook is located in the fixed groove, and the positioning groove and the moving groove are directly opposite each other. Under the action of the elastic element, one end of the locking block is located in the positioning groove, and the other end is located in the moving groove. Under the action of the locking block, the rotation of the rotating part in the circumferential direction is limited. At this time, the positioning block is located close to the tower body, and the insert is located in the slot. The positioning block positions the moving rod through the insert. The operator carries the unlocking rod. When unlocking is required, the unlocking rod is aligned with the hole, and the unlocking block is aligned with the clearance groove. The unlocking rod is moved axially along the through hole, so that the unlocking block enters the rotating groove along the clearance groove. The unlocking rod is rotated circumferentially, so that the unlocking block rotates along the rotating groove, and the positioning block is pushed out of the positioning groove, thereby completing the unlocking of the rotation of the rotating part in the circumferential direction. The operator continues to rotate the unlocking rod, so that the unlocking rod drives the rotating part to rotate, thereby separating the positioning hook from the fixed groove and releasing the positioning of the positioning block. The positioning block is moved along the length direction of the support part, so that the insert is separated from the slot, thereby releasing the positioning of the moving rod.

[0012] Optionally, the lower end of the positioning block is provided with a mounting hole, and a top block is slidably connected to the positioning block along the axis of the mounting hole. An elastic element two is provided between the top block and the positioning block. When the elastic element two is in a compressed state, it tends to drive the top block to move away from the positioning block. A push rod adapted to the top block is fixedly connected to the lower end of the support part.

[0013] By adopting the above technical solution, when the positioning block is in the unlocked state, the positioning block is moved along the length of the support, so that the push rod abuts against the top block and pushes the top block into the mounting hole. At this time, the elastic element 2 is in the compressed state, moving the moving rod along the moving trajectory away from the tower body. When the moving rod is in contact with the support again, the insert block and the slot are aligned. At this time, the elastic element 2 pushes the positioning block to move closer to the moving rod, so that the insert block is inserted into the slot, thereby repositioning the moving rod. This helps to improve the safety of operators when climbing by stepping on the pole.

[0014] Optionally, a trapezoidal block is fixed along the length direction on the side of the positioning block near the support, and a trapezoidal groove adapted to the trapezoidal block is opened along the length direction of the support. The trapezoidal block is located in the trapezoidal groove and is slidably connected to the positioning block along the length direction of the trapezoidal groove.

[0015] By adopting the above technical solution, the trapezoidal block and the trapezoidal groove cooperate to limit the positioning block, which helps to improve the connection stability between the positioning block and the support.

[0016] Optionally, a guardrail is provided between the tower leg and the tower body. The guardrail is horizontally arranged along the circumference of the tower body. Several straight bars are fixed at the lower end of the guardrail. The straight bars are arranged along the circumference of the guardrail. A movable opening is provided near the climbing component of the guardrail. A sealing door adapted to the movable opening is hinged to the guardrail. A hanging plate is hinged to the side of the sealing plate near the support. A fixing block is fixedly connected to the support. A positioning opening adapted to the fixing block is provided on the hanging plate. A protective cover adapted to the hanging plate is slidably connected to the support along its length. A moving component for moving the protective cover is provided between the protective cover and the moving bar.

[0017] By adopting the above technical solution, the guardrail and the straight bar work together to prevent people from climbing the tower. In the initial state, the hanging plate is in contact with the support. At this time, the positioning block passes through the positioning port to position the scraper, thus completing the positioning of the sealing door. When the moving bar is close to the tower, the connecting rod drives the protective cover to move to the outside of the hanging plate through the moving component. At this time, the protective cover positions the hanging plate, thereby reducing the probability of unauthorized personnel arbitrarily releasing the positioning side of the hanging plate. When the operator needs to use the step bar, the moving bar is moved away from the tower along the moving trajectory. When the moving bar moves, it drives the protective cover away from the sealing door through the moving component. At this time, the positioning of the hanging plate is released, making it easier for the operator to open the sealing door and enter the top of the guardrail through the moving port.

[0018] Optionally, the moving component includes a thick rod and a thin rod. The lower end of the thick rod is hinged to the upper end of the moving rod. The thin rod is inserted into the end of the thick rod away from the moving rod and is slidably connected to the thick rod in the circumferential direction. The end of the thin rod away from the thick rod is hinged to the lower end of the protective cover. The protective cover has an opening adapted to the thin rod.

[0019] By adopting the above technical solution, when the moving rod moves, it drives the thick rod to rotate. Through the connection between the thick rod and the thin rod, the rotation of the thick rod drives the rotation of the thin rod, which in turn drives the protective cover to move along the length of the support part. This achieves the connection between the moving rod and the protective cover, eliminating the need for operators to manually move the protective cover and improving the ease of use of the protective cover.

[0020] Optionally, an elastic pad is fixedly connected to the lower end of the cover, and when the upper end of the moving rod abuts against the side of the elastic pad away from the cover, the cover and the moving rod are in the same straight line.

[0021] By adopting the above technical solution, the elastic pad has a certain deformation capacity, which allows for a certain distance of movement between the protective cover and the moving rod, thus reducing the probability of the moving rod getting stuck with the protective cover when it moves.

[0022] In summary, this application includes at least one of the following beneficial technical effects: Four sets of tower legs work together to support the tower. In the initial state, the moving rod is in contact with the support and is located close to the tower. All the foot pedals are located within their respective openings. At this time, the support uses a positioning component to position the moving rod, reducing the probability of unauthorized personnel using the climbing mechanism. When the operator needs to climb the power tower, the positioning component is unlocked, and the moving rod is moved away from the tower along its trajectory. At this time, the linkage component moves the corresponding foot pedals out of their openings. When the moving rod is located away from the tower and is in contact with the support again, all the foot pedals are perpendicular to the moving rod, and the foot pedals and ladder are on the same side, making it easy for the operator to climb the ladder along all the foot pedals. When the step bar needs to be retracted, the operator moves the moving bar along the moving trajectory towards the tower body, so that the connecting component moves the step bar into the corresponding opening. The moving bar is then positioned by the positioning component, thus completing the fixation of the moving bar. By moving the moving bar along the moving trajectory, the step bar can be released and retracted. When climbing the power tower, the operator does not need to carry a moving ladder, which improves the convenience of the operator when climbing the power tower. When the moving rod is in contact with the support, the connecting rod is located in the placement slot. The placement slot is used to store the connecting rod. When the connecting rod moves along the moving trajectory, it drives the connecting rod to swing through the rotating disk. The swinging of the connecting rod drives the rotating disk to rotate, and then drives the sliding plate to slide along the length of the through slot through the meshing of the tooth block and the rack. When the sliding plate slides, it drives the corresponding pedal rod to rotate through two sets of top rods, thereby realizing the storage and release of the pedal rod. Initially, the positioning hook is located in the fixed groove, and the positioning groove and the moving groove are aligned. Under the action of the elastic element, one end of the locking block is located in the positioning groove, and the other end is located in the moving groove. Under the action of the locking block, the rotation of the rotating part in the circumferential direction is limited. At this time, the positioning block is located close to the tower body, and the insert is located in the slot. The positioning block positions the moving rod through the insert. The operator carries the unlocking rod. When unlocking is required, the unlocking rod is aligned with the hole, and the unlocking block is aligned with the clearance groove. The unlocking rod is moved axially along the through hole, so that the unlocking block enters the rotating groove along the clearance groove. The unlocking rod is rotated circumferentially, so that the unlocking block rotates along the rotating groove, and the positioning block is pushed out of the positioning groove, thus completing the unlocking of the circumferential rotation of the rotating part. The operator continues to rotate the unlocking rod, so that the unlocking rod drives the rotating part to rotate, thereby separating the positioning hook from the fixed groove and releasing the positioning of the positioning block. The positioning block is moved along the length of the support part, so that the insert is separated from the slot, thus releasing the positioning of the moving rod. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses an easy-to-climb power transmission tower. Example

[0034] Reference Figure 1 and Figure 2The power transmission tower is designed for easy climbing and includes a tower body 1 and four tower legs 2. All tower legs 2 are located at the lower end of the tower body 1 and are distributed along the side of the tower body 1. The tower legs 2 are fixedly connected to the tower body 1 and are used to support the tower body 1. A ladder 11 is installed on any side of the tower body 1, which facilitates operators to climb or descend along the tower body 1.

[0035] Reference Figure 1 and Figure 2 A climbing member 3 is provided near the tower leg 2 of the ladder 11. The climbing member 3 includes a support part 31 and a moving rod 32 that are parallel to each other. The support part 31 is fixed to the tower leg 2 along the length direction of the tower leg 2, and the moving rod 32 is located on the side of the support part 31 away from the tower leg 2. Multiple sets of foot pedals 321 are provided on both sides of the moving rod 32 along the length direction. The foot pedals 321 are arranged symmetrically in pairs with the moving rod 32 as the center. The connecting rod 41 has multiple openings 322 for placing the foot pedals 321. When the foot pedals 321 are stored in the openings 322, they are parallel to the moving rod 32.

[0036] Reference Figure 3 and Figure 4 The movable rod 32 is equipped with multiple sets of linkage components 4, each set of linkage components 4 corresponding to a set of pedal rods 321. Each linkage component 4 includes a connecting rod 41, a rotating disk 42, a sliding plate 43, and two sets of top rods 44. All connecting rods 41 are located between the movable rod 32 and the support part 31. The support part 31 has multiple placement slots 310 along its length that are adapted to the connecting rods 41. One end of the connecting rod 41 is located within the placement slot 310 and is hinged to the support part 31. A through slot 320 is opened on the side of the movable rod 32 near the support part 31. The rotating disk 42 is located within the through slot 320, and the axis of the rotating disk 42 is perpendicular to the length direction of the movable rod 32.

[0037] Reference Figure 3 and Figure 4 The rotating disk 42 is rotatably connected to the moving rod 32 in the circumferential direction. The end of the connecting rod 41 away from the support 31 is fixedly connected to the rotating disk 42. When the end of the connecting rod 41 away from the support 31 swings, it drives the moving rod 32 to move through the connection relationship of the rotating disk 42. The path of the moving rod 32 is set as the moving trajectory. The moving rod 32 moves along the moving trajectory towards the tower body 1 (reference). Figure 1 (Approaching or moving away) The sliding plate 43 is located within the through groove 320 and is slidably connected to the moving rod 32 along the length of the through groove 320. Multiple toothed blocks 421 are fixed circumferentially on the rotating disk 42, and a rack 431 that meshes with the toothed blocks 421 is fixed along the length of the sliding plate 43. When the connecting rod 41 swings, it drives the rotating disk 42 to rotate, and through the meshing action of the toothed blocks 421 and the rack 431, the rotating disk 42 drives the sliding plate 43 to move along the length of the rack 431.

[0038] Reference Figure 3and Figure 4 The top rod 44 and the foot pedal 321 correspond one-to-one. One end of the top rod 44 is hinged to the sliding plate 43. When the sliding plate 43 moves, it drives the top rod 44 to move. The other end of the top rod 44 is hinged to the foot pedal 321. When the top rod 44 moves, it drives the foot pedal 321 to swing. In the initial state, the moving rod 32 is in contact with the support part 31 and is located close to the tower body 1 (reference). Figure 1 At this position, all pedal levers 321 are retracted into the opening 322.

[0039] Reference Figure 5 and Figure 6 The lower end of the support part 31 is provided with a positioning component 5 (see reference). Figure 1 Positioning component 5 (reference) Figure 1 The device includes a positioning block 51, a rotating part 52, and an unlocking rod 53. The positioning block 51 is located at the lower end of the moving rod 32 and fits against the support part 31. A trapezoidal block 518 is fixedly connected to the positioning block 51 along its length. The support part 31 has a trapezoidal groove 313 that matches the trapezoidal block 518 (see reference). Figure 4 Trapezoidal block 518 is located in trapezoidal groove 313 (reference) Figure 4 Inside, and with trapezoidal groove 313 (reference) Figure 4 Inner wall fit.

[0040] Reference Figure 4 and Figure 6 The support part 31 limits the positioning block 51 by the cooperation of the trapezoidal block 518 and the trapezoidal groove 313, so that the positioning block 51 slides along the length direction of the support part 31 and restricts the tendency of the positioning block 51 to move away from the support part 31. The upper end of the positioning block 51 is fixed with an insert 511. When the positioning block 51 moves, it drives the insert 511 to move. The lower end of the moving rod 32 is provided with a slot 323 that matches the insert 511 (see reference). Figure 5 The rotating part 52 is cylindrical and is connected to the moving rod 32 (see reference). Figure 5 It is vertically set, and the rotating part 52 passes through the positioning block 51 and is rotatably connected to the positioning block 51.

[0041] Reference Figure 5 and Figure 7 The rotating part 52 is fixedly connected to a positioning hook 525 along its circumference. When rotating, the positioning hook 525 rotates. The support part 31 has a fixing groove 311 that matches the positioning hook 525. The positioning hook 525 passes through the positioning block 51 and is inserted into the fixing groove 311. The rotating part 52 has a positioning groove 521 on the side opposite to the positioning hook 525. The positioning block 51 has a moving groove 512 that matches the positioning groove 521. When the positioning hook 525 is engaged with the fixing groove 311, the moving groove 512 is aligned with the positioning groove 521. At this time, the insertion block 511 is inserted into the slot 323.

[0042] Reference Figure 5 and Figure 7 A locking block 513 is slidably connected to the positioning block 51 along the length of the moving groove 512. An elastic element 514 is provided between the positioning block 51 and the locking block 513. The elastic element 514 is preferably a spring, with one end fixedly connected to the locking block 513 and the other end fixedly connected to the positioning block 51. When the elastic element 514 is compressed, it pushes the locking block 513 along the moving groove 512 into the positioning groove 521, causing the locking block 513 to abut against the inner wall of the positioning groove 521. This limits the circumferential rotation of the rotating part 52, thus positioning the positioning hook 525. The positioning hook 525 and the fixing groove 311 (see reference) Figure 4 The positioning block 51 is used to position the moving rod 32, thereby restricting the movement of the moving rod 32 and reducing the probability of unauthorized personnel moving the moving rod 32 at will.

[0043] Reference Figure 6 and Figure 7 The unlocking rod 53 has an unlocking block 531 fixed circumferentially. The rotating part 52 has a through hole 522 adapted to the unlocking rod 53, which communicates with the positioning groove 521. The rotating part 52 also has a relief groove 523 communicating with the through hole 522 axially. When it is necessary to release the positioning of the positioning block 51, the operator aligns the unlocking rod 53 with the through hole 522 and aligns the unlocking block 531 with the relief groove 523. The unlocking rod 53 is moved axially along the through hole 522, causing the unlocking block 531 to enter the rotating groove 524 along the relief groove 523. The unlocking rod 53 is rotated circumferentially, causing the unlocking rod 53 to drive the unlocking block 531 to rotate along the rotating groove 524 toward the positioning groove 521. The unlocking block 531 has a guide surface on the side near the locking block. When the unlocking block 531 moves toward the positioning groove 521, it drives the guide surface to move toward the lower end of the locking block 513.

[0044] Reference Figure 5 and Figure 7 As the unlocking block 531 gradually enters the positioning groove 521, the locking block 513 is pushed out of the positioning groove 521 by the guide surface, thereby releasing the positioning of the rotating part 52. When the operator continues to rotate the unlocking rod 53, the unlocking block 531 fits against the inner wall of the positioning groove 521, thereby driving the rotating part 52 to rotate. This causes the rotating part 52 to move the positioning hook 525 out of the fixed groove 311, thereby releasing the positioning of the positioning block 51. Moving the positioning block 51 away from the moving rod 32 along the support part 31 separates the insertion block 511 from the slot 323, thereby releasing the positioning of the moving rod 32. The operator carries the unlocking rod 53 with them, which helps to reduce the probability of unauthorized personnel unlocking the positioning block 51.

[0045] Reference Figure 1 and Figure 3The operator moves the movable rod 32 along the moving trajectory away from the tower body 1. When the movable rod 32 moves, it drives the foot pedal 321 to move out of the opening 322 through the linkage component 4. When the movable rod 32 re-enters the support part 31 (reference) Figure 2 When in contact with the moving rod 32, all the step bars 321 are perpendicular to each other. This makes it easier for operators to climb the ladder 11 from bottom to top along the step bars 321. When operators need to climb the ladder 11 to the top of the tower 1 to perform maintenance or repairs on the power tower, they do not need to carry a mobile ladder with them, which improves the convenience of operators climbing the power tower.

[0046] Reference Figure 1 and Figure 5 The positioning block 51 has a mounting hole 515 at its lower end along its length. The positioning block 51 has a top block 516 that matches the mounting hole 515. The top block 516 is located within the mounting hole 515 and is slidably connected to the positioning block 51 along the length of the mounting hole 515. The top block 516 has a second elastic element 517, preferably a spring. One end of the spring is fixedly connected to the top block 516, and the other end is fixedly connected to the positioning block 51. A push rod 312, directly opposite the top block 516, is fixedly attached to the lower end of the support part 31. After unlocking the positioning block 51, the positioning block 51 is moved towards the push rod 312, releasing the positioning of the moving rod 32 and simultaneously avoiding it.

[0047] Reference Figure 1 and Figure 5 When the positioning block 51 is moved, the push rod 312 abuts against the top block 516, pushing the top block 516 into the mounting hole 515. At this time, the elastic element 517 is in a compressed state. The operator presses the positioning block 51 to limit its movement. The moving rod 32 is moved away from the tower body 1 along the moving trajectory. When the moving rod 32 is in contact with the support part 31 again, the slot 323 and the insert block 511 are aligned. At this time, the pressure on the positioning block 51 is released, causing the elastic element 517 to push the positioning block 51 closer to the moving rod 32, and the insert block 511 is inserted into the slot 323 again, thereby positioning the moving rod 32. This helps to improve the placement stability of the moving rod 32, reduces the probability of the moving rod 32 shaking when the operator uses the step rod 321, and thus improves the operator's work safety.

[0048] Reference Figure 1 and Figure 2A guardrail 6 is installed at the connection between the tower body 1 and the tower leg 2. The guardrail 6 is horizontally arranged around the circumference of the tower body 1. By setting up the guardrail 6, it is beneficial to block unauthorized personnel and reduce the probability of unauthorized personnel climbing the power transmission tower at will. Multiple evenly distributed straight bars 61 are fixed around the circumference of the guardrail 6. The straight bars 61 extend away from the guardrail 6, which helps to further improve the blocking effect of the guardrail 6. The guardrail 6 has a movable opening 62 facing the climbing component 3, which allows operators to pass through the guardrail 6. The guardrail 6 also has a sealing door 63 adapted to the movable opening 62. The sealing door 63 is hinged to the guardrail 6, so that the movable opening 62 is blocked when the climbing component 3 is not in operation.

[0049] Reference Figure 2 and Figure 8 A hanging plate 631 is hinged to the lower end of the sealing door 63. When the sealing door 63 opens and closes, it moves the hanging plate 631. A fixing block 315 adapted to the scraper is fixed to the support part 31. The hanging plate 631 has a positioning hole 632. When the hanging plate 631 abuts against the support part 31, the fixing block 315 passes through the positioning hole 632 and contacts the scraper. The support part 31 positions the hanging plate 631 through the fixing block 315, and then positions the sealing door 63 through the hanging plate 631. A protective cover 314 is slidably connected to the support part 31 along its length. The protective cover 314 is located near the tower body 1 on the moving rod 32 (reference). Figure 1 One end of the cover 314 is fixed with an elastic pad 317, and the lower end of the cover 314 is fixed with an elastic pad 317. When the moving rod 32 is in contact with the support 31, and the moving rod 32 is located near the tower body 1 (reference). Figure 1 When the position is such that the upper end of the moving rod 32 abuts against the side of the elastic pad 317 away from the cover 314, the moving rod 32 is in contact with the elastic pad 317.

[0050] Reference Figure 2 and Figure 8 The movable rod 32 positions the protective cover 314. At this time, the hanging plate 631 is located between the protective cover 314 and the support part 31. The protective cover 314 limits the hanging plate 631, reducing the probability of unauthorized personnel opening the sealing door 63 at will. A movable component 33 is provided between the protective cover 314 and the movable rod 32. The movable component 33 includes a thick rod 331 and a thin rod 332. The thin rod 332 is arranged parallel to the thick rod 331 and is inserted into the thick rod 331 axially. It is also slidably connected to the thick rod 331 along its length. The end of the thick rod 331 away from the thin rod 332 is hinged to the movable rod 32. When the movable rod 32 moves, it drives the thick rod 331 to rotate.

[0051] Reference Figure 2 and Figure 8The end of the thin rod 332 furthest from the thick rod 331 is hinged to the protective cover 314, so that when the thick rod 331 moves, it drives the protective cover 314 to move via the thin rod 332. When the moving rod 32 moves away from the tower body 1 along the moving trajectory, it drives the protective cover 314 away from the sealing door 63 via the thick rod 331 and the thin rod 332. The elastic pad 317 has a certain deformation capacity, which helps to reduce the probability of the moving rod 32 getting stuck with the protective cover 314 when it moves, thus making it easier for the operator to release the positioning of the sealing door 63. The operator moves the moving rod 32 along the moving trajectory closer to the tower body 1 (reference). Figure 1 When the moving rod 32 moves in the direction of the thick rod 331 and the thin rod 332, it pushes the cover 314 to close the door 63, thereby sealing the hanging plate 631 through the cover 314. This eliminates the need for operators to manually move the cover 314, improving the ease of use of the cover 314.

[0052] The implementation principle of the climbable power transmission tower in this embodiment is as follows: the tower legs 2 support the tower body 1, and the guardrail 6 cooperates with the straight bar 61 to reduce the probability of unauthorized personnel climbing the power transmission tower at will. At this time, the movable bar 32 is in contact with the support part 31 and is located close to the tower body 1. At this time, all the step bars 321 are stored in the opening 322, and the positioning block 51 positions the movable bar 32 through the insert block 511. When the operator needs to use the climbing component 3, the positioning block 51 is unlocked by the unlocking rod 53. Moving the positioning block 51 separates the insertion block 511 from the slot 323. Under the connection of all the connecting rods 41, the moving rod 32 moves along the movement trajectory away from the tower body 1. As the moving rod 32 moves, it causes the connecting rod 41 to swing, which in turn causes the rotating disk 42 to rotate. Through the meshing of the toothed block 421 and the rack 431, the rotating disk 42 causes the sliding plate 43 to slide along the length of the moving rod 32. This allows the sliding plate 43 to move the stepping rod 321 out of the opening 322 via the top rod 44. When the moving rod 32 is located away from the tower body 1 and in contact with the support part 31, all the stepping rods 321 are perpendicular to the moving rod 32. The operator then climbs up the ladder 11 along the stepping rods 321. This eliminates the need for the operator to carry a mobile ladder when climbing the power tower, improving the convenience of climbing the power tower.

[0053] 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.
