Description

Technical Field

[0001] This invention relates to the field of power transmission operation and maintenance technology, and in particular to a fall arrestor ring for power transmission towers and its installation method. Background Technology

[0002] When transmission lines experience defects or faults, maintenance personnel must climb towers (iron towers, steel pipe poles, etc.) to work. Protective measures are necessary during these ascents and descents to prevent falls from heights. Previously, transmission line maintenance professionals used safety belts and backup safety ropes to protect themselves when climbing towers. However, most iron towers lack fall arrestor rails, rendering safety belts and backup safety ropes unusable during ascents, posing a risk of falls from heights. Currently, the double-hook safety ropes are impractical, being inconvenient to carry and physically demanding.

[0003] Currently, there is a structure that combines an insulated rope with a differential self-locking device to assist maintenance personnel in climbing towers. Specifically, a hook is attached to the top of the insulated rope and hooked onto the angle iron at the top of the tower. Then, the maintenance personnel install the differential self-locking device on the insulated rope, with the device positioned around their waist. In the event of a fall, the differential self-locking device can quickly lock onto the insulated rope, protecting the maintenance personnel. It is also convenient to carry and saves the maintenance personnel's physical strength. However, in actual use, maintenance personnel need to first climb to the top of the tower, hook the hook onto the angle iron, and then seal the hook opening to prevent it from falling off. The installation requires workers to climb the tower, which is time-consuming, laborious, and inconvenient. Summary of the Invention

[0008] In one embodiment of the present invention, a limiting block is provided on the surface of the mounting bracket above the mounting opening, and a docking notch is provided on the bottom surface of the limiting block, the docking notch being matched with the size of the angle iron at the top of the transmission tower.

[0009] In one embodiment of the present invention, the bottom surface of the limiting block is provided with a pair of guide plates based on central symmetry. The bottom end of the guide plate is disposed on the surface of the mounting bracket, and the top end is aligned with the boundary of the docking notch. When the top angle iron of the transmission tower enters the mounting opening, the pair of guide plates can guide the top angle iron of the transmission tower to move into the docking notch.

[0010] In one embodiment of the present invention, a top rod is inserted through the notch, the top end of the top rod extends to the top of the hanger, an air box is provided at the top of the hanger, the top end of the top rod passes through the air box and is provided with a first air plate at the top end, partitions are slidably connected to both sides of the first air plate, and air leakage holes are opened on the sides of the partitions; a second air plate is provided inside the air box and on the side of the partition away from the first air plate, a compression rod is vertically provided on the bottom surface of the second air plate, the bottom end of the compression rod passes through the air box and points to both sides of the hanger; a rubber block is provided at the bottom end of the compression rod.

[0011] In one embodiment of the present invention, the extrusion rod includes a first connecting rod and a second connecting rod; the bottom end of the second connecting rod is mounted on the top end of the rubber block, the top end of the first connecting rod is connected to the second air plate and the bottom end is provided with an insertion groove; the top end of the second connecting rod is inserted into the insertion groove, and the side of the first connecting rod is provided with a plurality of first insertion holes in the vertical direction; the side of the second connecting rod is provided with a plurality of second insertion holes in the vertical direction; the first insertion holes communicate with the insertion groove; and a fixing bolt is inserted into the first insertion hole, the end of the fixing bolt is restricted by a nut and the fixing bolt passes through the second insertion hole.

[0016] S2. The drone moves the mounting frame upwards via the hook and the second hanging ring. Due to the downward pull of the insulating rope on the first hanging ring, the deflection plate deflects relative to the mounting frame under the pull of the hook and the insulating rope, thus opening the mounting opening.

[0017] S3. Then control the position of the hanging opening so that the angle iron at the top of the tower passes through the hanging opening, so that the hanging bracket is hung on the angle iron.

[0018] S4. Then, control the drone to drive the hook to detach from the second hook ring. The second hook ring is no longer under tension, and under the action of the first spring, the hook opening is sealed again.

[0020] The technical solution of the present invention has the following advantages compared with the prior art:

[0021] 1. The present invention discloses a power tower anti-fall ring and its installation method. By setting up a mounting bracket, in use, the top of the hook is connected to the bottom of a drone, and the insulating rope is connected to the first mounting ring. Then, the drone is controlled to take off upward. The drone moves the mounting bracket upward through the hook and the second mounting ring, opening the mounting opening. Then, the position of the mounting opening is controlled so that the angle iron at the top of the tower passes through the mounting opening, thus the mounting bracket is attached to the angle iron. Afterward, the drone is controlled to move the hook away from the second mounting ring, and the mounting opening is sealed again. This achieves automatic sealing and closure of the mounting bracket after it is attached to the angle iron. It eliminates the need for maintenance personnel to climb to the top of the tower to attach the hook to the angle iron and then seal the hook opening to prevent it from falling off; it is time-saving, labor-saving, and convenient.

[0022] 2. The present invention provides a power tower anti-fall hanging ring and its installation method, which, by setting a limiting block, controls the position of the hanging frame by a drone when the angle iron passes through the hanging opening, thereby controlling the position of the limiting block, so that the angle iron is embedded in the docking notch on the bottom surface of the limiting block, thereby improving the stability of the hanging.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0035] Reference Figure 1-2 As shown, a power tower anti-fall ring of the present invention includes a mounting frame 1 with a mounting opening; a first hanging ring 13 is provided at the bottom of the mounting frame 1 for attaching an insulating rope; a deflecting plate 11 is rotatably connected to the side of the mounting frame 1, initially the bottom of the deflecting plate 11 is directly below the mounting opening; a second hanging ring 12 is provided at the top of the deflecting plate 11, and a hook 17 is attached inside the second hanging ring 12; the top of the hook 17 is connected to a drone; a locking plate 15 is provided at the bottom of the side of the deflecting plate 11, initially the locking plate 15 cooperates with the deflecting plate 11 to seal the mounting opening; a first spring 14 is provided between the deflecting plate 11 and the mounting frame 1.

[0036] In this embodiment of the invention, the top of the hook 17 is connected to the bottom of the drone, and the insulating rope is connected to the first hanging ring 13. Then, the drone is controlled to take off upwards. The drone moves the mounting frame 1 upwards via the hook 17 and the second hanging ring 12. Because the first hanging ring 13 is pulled downwards by the insulating rope, the deflection plate 11 deflects relative to the mounting frame 1 under the tension of the hook 17 and the insulating rope, causing the first spring 14 to be stretched. The bottom end of the deflection plate 11, located below the mounting opening, moves the locking plate 15, opening the mounting opening. Then, the drone is controlled to take off upwards. The position of the hook opening is controlled so that the angle iron at the top of the tower passes through the hook opening. Even if the hook frame 1 is hooked onto the angle iron, the drone is then controlled to drive the hook 17 to disengage from the second hanging ring 12. The second hanging ring 12 is no longer under tension. Under the action of the first spring 14, the deflection plate 11 is deflected relative to the hook frame 1, and the bottom end drives the locking plate 15 to seal the hook opening again. This achieves automatic sealing and closure of the hook frame 1 after it is hooked onto the angle iron. It eliminates the need for maintenance personnel to climb to the top of the tower to hook the hook onto the angle iron and then seal the hook opening to prevent it from falling off. It is time-saving, labor-saving, and more convenient.

[0037] Reference Figure 2-3 As shown, a filling plate 16 is provided on the side of the card plate 15 facing the hanging frame 1. The filling plate 16 is slidably connected to the side of the hanging frame 1. When the card plate 15 blocks the hanging opening, the card plate 15 drives the filling plate 16 to move synchronously. The filling plate 16 is continuously attached to the side of the hanging frame 1 to avoid the card plate 15 and the hanging frame 1 from intersecting and creating gaps, which would affect the sealing effect.

[0038] A retaining strip 2 is provided at the bottom of the deflection plate 11, and a connecting plate 21 is provided on the side of the deflection plate 11. A second spring 22 is provided between the connecting plate 21 and the retaining plate 15. When the angle iron passes through the hooking notch, the angle iron can squeeze the retaining plate 15 that has not completely left, causing the retaining plate 15 to deflect relative to the deflection plate 11, compressing the second spring 22, increasing the hooking opening, and thus facilitating the entry of the angle iron during hooking. After the retaining plate 15 is reset, the retaining strip 2 will hook the retaining plate 15 to prevent the retaining plate 15 from stretching the second spring 22 and deflecting, ensuring complete sealing of the hooking opening.

[0039] Reference Figure 4-8 As shown, a limiting block 3 is provided on the surface of the mounting bracket 1 above the mounting opening. The bottom surface of the limiting block 3 has a docking notch 31, which matches the size of the angle iron at the top of the transmission tower. When the angle iron passes through the mounting opening, the position of the mounting bracket 1 is controlled by a drone, which in turn controls the position of the limiting block 3, so that the angle iron is embedded in the docking notch 31 on the bottom surface of the limiting block 3, thereby improving the stability of the mounting.

[0040] The bottom surface of the limiting block 3 is provided with a pair of guide plates 4 based on central symmetry. The bottom end of the guide plate 4 is set on the surface of the hanging frame 1, and the top end is aligned with the boundary of the docking notch 31. When the angle iron at the top of the transmission tower enters the hanging opening, the pair of guide plates 4 can guide the angle iron at the top of the transmission tower to move into the docking notch 31. When the angle iron passes through the hanging opening, it is restricted by the pair of guide plates 4 and moves precisely in the direction of the docking notch 31, so that the angle iron can be embedded into the docking notch 31.

[0041] A push rod 5 is inserted through the notch 31. The top end of the push rod 5 extends to the top of the hanger 1. An air box 51 is installed at the top of the hanger 1. The top end of the push rod 5 passes through the air box 51 and is equipped with a first air plate 52. Partitions 53 are slidably connected to both sides of the first air plate 52. Leakage holes are opened on the sides of the partitions 53. A second air plate 54 is installed inside the air box 51 and on the side of the partitions 53 away from the first air plate 52. A compression rod 55 is vertically installed on the bottom surface of the second air plate 54, and the bottom end of the compression rod 55 extends through... The pressure rod 55 is positioned at the bottom of the air box 51 and points to both sides of the mounting bracket 1. A rubber block 56 is provided at the bottom of the pressure rod 55. When the angle iron is embedded in the docking notch 31, it presses the bottom of the top rod 5. The top rod 5 drives the first air plate 52 to move upward in the air box 51, which compresses the gas inside the air box 51 and increases the air pressure. Under the action of the air pressure, the second air plate 54 drives the rubber block 56 at the bottom of the pressure rod 55 to move downward, pressing the top surface of the angle iron and generating braking friction, which restricts the mounting bracket 1 from sliding on the angle iron and improves the stability of the mounting.

[0042] The extrusion rod 55 includes a first connecting rod 551 and a second connecting rod 553; the bottom end of the second connecting rod 553 is installed on the top end of the rubber block 56, the top end of the first connecting rod 551 is connected to the second air plate 54 and the bottom end is provided with an insertion groove; the top end of the second connecting rod 553 is inserted into the insertion groove, and the side of the first connecting rod 551 is provided with a plurality of first insertion holes 552 in the vertical direction; the side of the second connecting rod 553 is provided with a plurality of second insertion holes 554 in the vertical direction; the first insertion holes 552 communicate with the insertion groove; and the first insertion holes 552 are connected to the insertion groove. A fixing bolt 6 is inserted, the end of the fixing bolt 6 is restricted by a nut and the fixing bolt 6 passes through the second insertion hole 554; when the rubber block 56 wears out after repeated use, by controlling the total length of the first connecting rod 551 and the second connecting rod 553, the fixing bolt 6 is used to fix the docking position of the first connecting rod 551 and the second connecting hole 552 and the second insertion hole 554, thereby adjusting the lowest position of the rubber block 56 so that the rubber block 56 can fully squeeze the top surface of the angle iron, effectively achieving the anti-slip effect of the hanging bracket 1.

[0043] Multiple limiting blocks are evenly arranged on the inner ring surface of the second hanging ring 12; when the hook 17 is attached to the second hanging ring 12, the attachment position can be limited by the limiting blocks; when the hook 17 is attached to the inside of the second hanging ring 12, the hook 17 is limited between the limiting blocks, ensuring that the second hanging ring 12 remains stable relative to the hook 17 when it is attached.

[0044] The surface of the mounting bracket 1 is coated with an insulating layer to prevent static electricity on the pole from affecting the mounting bracket 1.

[0045] Reference Figure 9 As shown, a method for installing a fall arrestor ring on a power transmission tower includes the following steps:

[0046] S1. When in use, connect the top of the hook 17 to the bottom of the drone and connect the insulating rope to the first hanging ring 13, then control the drone to take off upwards.

[0047] S2. The drone moves the mounting frame 1 upward through the hook 17 and the second hanging ring 12. Due to the downward pulling force of the insulating rope on the first hanging ring 13, the deflection plate 1 deflects relative to the mounting frame 1 under the action of the hook 17 and the pulling force of the insulating rope, so that the mounting opening is opened.

[0048] S3. Then control the position of the hanging opening so that the angle iron at the top of the tower passes through the hanging opening, so that the hanging bracket 1 is hung on the angle iron.

[0049] S4. Then, control the drone to drive the hook 17 to disengage from the second hanging ring 12. The second hanging ring 12 is no longer under tension, and under the action of the first spring 14, the hook opening is sealed again.

[0050] S5. When removing the mounting bracket 1, the second hanging ring 12 is pulled up by the drone and the hook 17, thereby opening the mounting opening.

[0051] During operation, the top of hook 17 is connected to the bottom of the drone, and the insulating rope is connected to the first hanging ring 13. The drone is then controlled to take off upwards. The drone, via hook 17 and the second hanging ring 12, moves the mounting bracket 1 upwards. Due to the downward pull of the insulating rope on the first hanging ring 13, the deflection plate 11 deflects relative to the mounting bracket 1 under the combined force of the hook 17 and the insulating rope. This stretches the first spring 14. The bottom end of the deflection plate 11, located below the mounting opening, moves the locking plate 15, opening the mounting opening. The position of the mounting opening is then controlled so that the angle iron at the top of the tower passes through the mounting opening, thus attaching the mounting bracket 1 to the angle iron. Then, the drone is controlled to drive the hook 17 to detach from the second hanging ring 12. The second hanging ring 12 is no longer under tension. Under the action of the first spring 14, the deflection plate 11 is deflected relative to the hanging frame 1. The bottom end drives the clamping plate 15 to seal the hanging opening again, thereby realizing the automatic sealing and closing of the hanging frame 1 after it is hooked to the angle iron. There is no need for maintenance personnel to climb to the top of the tower to hook the hook onto the angle iron and then seal the hook opening to prevent it from falling off. When the clamping plate 15 seals the hanging opening, the clamping plate 15 drives the filling plate 16 to move synchronously. The filling plate 16 is continuously attached to the side of the hanging frame 1 to avoid the clamping plate 15 and the hanging frame 1 from intersecting and creating gaps, which would affect the sealing effect.

[0052] When the angle iron passes through the hooking notch, it can squeeze the notch 15 that has not completely left, causing the notch 15 to deflect relative to the deflection plate 11, compressing the second spring 22, increasing the hooking opening, and thus facilitating the entry of the angle iron during hooking. After the notch 15 is reset, the clip 2 will hook the notch 15. When the angle iron passes through the hooking opening, the position of the hooking frame 1 is controlled by the drone, thereby controlling the position of the limiting block 3, so that the angle iron is embedded in the docking notch 31 on the bottom surface of the limiting block 3.

[0053] When the angle iron at the top of the transmission tower enters the mounting opening, a pair of guide plates 4 guide the angle iron to move into the docking notch 31. As the angle iron passes through the mounting opening, it is restricted by the guide plates 4, moving precisely towards the docking notch 31 to facilitate its insertion. When the angle iron is inserted into the docking notch 31, it presses against the bottom end of the top rod 5. The top rod 5 drives the first air plate 52 to move upward within the air box 51, compressing the gas inside the air box 51 and increasing the air pressure. Under this pressure, the second air plate 54 drives the rubber block 56 at the bottom of the compression rod 55 to move downward, pressing against the top surface of the angle iron and generating braking friction, restricting the sliding of the mounting bracket 1 on the angle iron. The system offers high stability during connection. When the rubber block 56 wears out after repeated use, the overall length of the first connecting rod 551 and the second connecting rod 553 is controlled. The fixing bolts 6, in conjunction with the first insertion hole 552 and the second insertion hole 554, fix the connection position of the first connecting rod 551 and the second connecting rod 553, thereby adjusting the lowest position of the rubber block 56. This allows the rubber block 56 to fully compress the top surface of the angle iron, effectively achieving an anti-slip effect on the connection frame 1. When the hook 17 is attached to the inside of the second hanging ring 12, the hook 17 is confined between the limiting blocks, ensuring that the second hanging ring 12 remains stable relative to the hook 17 during connection. The surface of the connection frame 1 is coated with an insulating layer to prevent static electricity on the tower from affecting the connection frame 1.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
