Description

Technical Field

[0001] The present invention relates to the technical field of power engineering, and specifically to a safety device for preventing falling of iron towers. Background Art

[0002] A power transmission tower, also known as a power tower or a transmission line tower, is an essential component in the power transmission system. It can effectively support and protect the electric wires in the air, while providing stable support for the wires. The structure of a power transmission tower includes multiple key parts such as a top frame, a lightning protection wire, conductors, a tower body, and tower legs. The top frame is mainly responsible for supporting the overhead wires to ensure their stability and safety; the lightning protection wire is used to reduce the potential risk brought by lightning strikes; the conductors are responsible for conducting electric current and are the core components of power transmission; while the tower body and tower legs jointly bear the heavy responsibility of supporting the entire tower to ensure its stability and non-collapse.

[0003] After investigation, a Chinese invention patent discloses a safety device for preventing falling of iron towers (publication number: CN115487438B), which includes a first locking mechanism, a second locking mechanism, a first unlocking mechanism, and a second unlocking mechanism. It can ensure that during the process of a worker climbing the iron tower, the left hand holds the first locking mechanism and the first unlocking mechanism, and the right hand holds the second locking mechanism and the second unlocking mechanism. Pressing the first unlocking mechanism with the left hand can unlock the second hook of the right hand, enabling the right hand to move forward one step upward. Then, pressing the second unlocking mechanism with the right hand unlocks the first hook of the left hand, enabling the left hand to move forward one step upward. In this way, the left and right hands alternate upward climbing reciprocally, ensuring that there is always one of the first locking mechanism and the second locking mechanism that can provide anti-fall protection for the worker. This safety device for preventing falling of iron towers has a simple structure, improves the climbing speed of the worker on the iron tower and the maintenance efficiency, and ensures the personal safety of the worker during the process of climbing the iron tower.

[0004] Although the above patent, through the setting of the first locking mechanism and the first unlocking mechanism, enables the left and right hands to alternate upward climbing reciprocally, ensuring that there is always one of the first locking mechanism and the second locking mechanism that provides anti-fall protection for the worker, and this safety device for preventing falling of iron towers has a simple structure, improves the climbing speed of the worker on the iron tower and the maintenance efficiency, and ensures the personal safety of the worker during the process of climbing the iron tower. However, when using this safety device for preventing falling of iron towers to climb the tower, it is necessary to coordinate the hands and feet with each other. In the above existing technology, only the hands can be used to climb the tower, and the feet need the worker's own strength to contact the iron tower. As a result, during the process of climbing the tower by the worker, more strength is required, causing excessive physical consumption of the worker when climbing the tower, and making it inconvenient for the worker to operate the iron tower.

[0005] Therefore, the present invention provides a safety device for preventing falling of iron towers to solve the above problems. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention provides a tower anti-falling safety device, as Figure 1 - Figure 7 shown. The tower anti-falling safety device includes two hand locking mechanisms and two foot locking mechanisms. The two foot locking mechanisms correspond to the two hand locking mechanisms one by one. A protective mechanism is commonly installed on the surfaces of the two hand locking mechanisms and the two foot locking mechanisms. The protective mechanism includes four steel wire ropes 19 respectively fixedly connected to the surface of the mounting block 1. One ends of the four steel wire ropes 19 are commonly fixedly connected to a protective vest 20. Through the arrangement of the steel wire ropes 19, the protective vest 20 is connected to the hand locking mechanism and the foot locking mechanism, further protecting the staff; The surface of the protective vest 20 is provided with through grooves corresponding to the hands and neck. One side of the protective vest 20 is provided with ventilation grooves 21 in a path array. The protection mechanism further includes collection bags 22 fixedly connected to both sides of the protective vest 20. Strong magnetic blocks 23 are placed inside the collection bags 22. The strong magnetic blocks 23 correspond to the existing iron tower guide rails. The strong magnetic blocks 23 are fixedly connected to the collection bags 22 through wires. Through the arrangement of the ventilation grooves 21, the air permeability of the protective vest 20 is improved, making it more comfortable for the staff to wear. And through the arrangement of the strong magnetic blocks 23, when the staff climbs to the required position, the two strong magnetic blocks 23 are taken out and adsorbed on the guide rail, so that the staff is safer when operating on the iron tower; Both the foot locking mechanism and the hand locking mechanism include mounting blocks 1. Two corresponding clamping blocks 2 are slidably connected to one side of the mounting blocks 1. When the staff climbs the tower, the left hand lifts the corresponding mounting block 1 and the handle 15, so that the corresponding clamping block 2 slides on the guide rail to change the position of the clamping block 2. An adjusting mechanism is installed on the surface of the mounting block 1. The adjusting mechanism includes a fixing plate 13 fixedly connected to one side of the mounting block 1. A bidirectional threaded rod 14 is rotatably connected inside the fixing plate 13. Two corresponding clamping blocks 2 are respectively threadedly connected to both sides of the bidirectional threaded rod 14. The protective vest 20 is worn on the body of the staff climbing the tower. According to the width of the guide rail on the iron tower, the bidirectional threaded rod 14 is rotated, so that the corresponding clamping block 2 slides on the corresponding mounting block 1, and the distance between the two corresponding clamping blocks 2 is adjusted to make the clamping block 2 more suitable for the guide rail. One end of the bidirectional threaded rod 14 is fixedly connected with a knob. Through the setting of the knob, it is more convenient to rotate the bidirectional threaded rod 14; Guide balls 3 are rotatably connected inside the clamping blocks 2. A pressing plate 4 slidably connected to the clamping block 2 is sleeved on the surface of the guide balls 3. Two linkage rods 18 fixedly connected to the pressing plate 4 are slidably connected to one side of the clamping block 2. One ends of the two linkage rods 18 are fixedly connected together with a baffle. Through the mutual cooperation of the linkage rods 18 and the baffle, the pressing plate 4 slides more stably; The pressing plate 4 corresponds to the guide ball 3. A sliding plate 5 slidably connected to the inside of the clamping block 2 is fixedly connected to the surface of the pressing plate 4. A return spring 6 is fixedly connected to one side of the sliding plate 5. A pulling rod 7 is sleeved inside the two return springs 6 together. A guide groove 24 is formed on the inner arc surface of the clamping block 2. The return spring 6 is installed inside the guide groove 24. The pulling rod 7 is slidably connected to the guide groove 24. The sliding plate 5 is slidably connected to the inside of the guide groove 24. The left hand squeezes the push rod 16 to drive the push plate 8 to move, so that the push plate 8 drives the corresponding pulling rod 7 to move, so that the sliding plate 5 drives the pressing plate 4 to limit the corresponding guide ball 3, so that the left hand is connected to the iron tower. Then lift the right foot to make the clamping block 2 slide on the guide rail to adjust the body position of the staff; The surfaces of the two pulling rods 7 are respectively attached with a pushing plate 8 and a conical plate 9. The mounting block 1 drives the conical plate 9 to slide through the connecting rope 17, so that the conical plate 9 no longer limits the corresponding pulling rod 7. Thus, due to the elastic force of the return spring 6, the pulling rod 7 moves, causing the sliding plate 5 to drive the pressing plate 4 to move, so that the pressing plate 4 no longer limits the corresponding guide ball 3, and the clamping block 2 of the foot locking mechanism no longer tightly clamps on the guide rail; The hand locking mechanism further includes a handle 15 fixedly connected to the corresponding mounting block 1. A push rod 16 fixedly connected to the pushing plate 8 is slidably connected inside the handle 15. The push rod 16 corresponds to the handle 15. The pushing plate 8 and the conical plate 9 are respectively slidably connected to the corresponding mounting block 1. The pulling rod 7 is slidably connected to the mounting block 1. A connecting rope 17 with elasticity is fixedly connected to the relative sides of the corresponding mounting block 1 and the conical plate 9. The foot locking mechanism further includes a clamping mechanism installed on one side of the corresponding mounting block 1. The clamping mechanism includes a foot pad 10 fixedly connected to one side of the corresponding mounting block 1. A bearing plate fixedly connected to the corresponding mounting block 1 is fixedly connected to the lower surface of the foot pad 10. One side of the upper surface of the foot pad 10 is rotatably connected by a pin shaft to a limiting plate 11. Two clamping tubes 12 corresponding to the foot pad 10 are fixedly connected to one side of the limiting plate 11. The limiting plate 11 corresponds to the mounting block 1. The staff holds the handle 15 with both hands and places both feet on the foot pad 10. Through the mutual cooperation of the limiting plate 11 and the clamping tubes 12, the feet are limited to prevent the feet from detaching from the foot pad 10 during use; Based on the repeated movements of the left hand and right foot and the right hand and left foot, when the staff climbs the tower, one of the hand locking mechanisms and the foot locking mechanism are always connected to the guide rail at the same time, so that one hand and one foot are connected to the iron tower, making the staff safer when climbing the tower.

[0020] Specifically, when the anti-falling safety device of the iron tower is in use: wear the protective vest 20 on the body of the staff climbing the tower. According to the width of the guide rail on the iron tower, rotate the bidirectional threaded rod 14, so that the corresponding clamping block 2 slides on the corresponding mounting block 1, adjust the distance between the two corresponding clamping blocks 2, make the clamping block 2 more adaptable to the guide rail. Then the staff holds the handle 15 with both hands and places both feet on the foot pad 10. Through the mutual cooperation of the limiting plate 11 and the clamping tubes 12, the feet are limited to prevent the feet from detaching from the foot pad 10 during use; When the staff climbs the tower, the left hand lifts the corresponding mounting block 1 and the handle 15, so that the corresponding clamping block 2 slides on the guide rail, changing the position of the clamping block 2. At the same time, the mounting block 1 drives the conical plate 9 to slide through the connecting rope 17, so that the conical plate 9 no longer limits the corresponding pulling rod 7. Thus, through the elastic force of the return spring 6, the pulling rod 7 moves, so that the sliding plate 5 drives the pressing plate 4 to move, so that the pressing plate 4 no longer limits the corresponding guide ball 3, and the clamping block 2 of the foot locking mechanism no longer tightly clamps on the guide rail. At the same time, the left hand squeezes the push rod 16 to drive the push plate 8 to move, so that the push plate 8 drives the corresponding pulling rod 7 to move, so that the sliding plate 5 drives the pressing plate 4 to limit the corresponding guide ball 3, connecting the left hand to the iron tower. Then, lift the right foot, so that the clamping block 2 slides on the guide rail to adjust the body position of the staff; Based on the repeated movements of the left hand and right foot and the right hand and left foot, when the staff climbs the tower, one of the hand locking mechanisms and the foot locking mechanism are always connected to the guide rail at the same time, connecting one hand and one foot to the iron tower, so that the staff is safer when climbing the tower. Avoiding the panic of the staff due to the existence of a window period when adjusting the positions of the hand locking mechanism and the foot locking mechanism. At the same time, through the mutual cooperation of the hand locking mechanism, the foot locking mechanism and the protection mechanism, the staff is safer when climbing the tower and prevents the staff from falling.

[0021] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
