Description

Technical Field

[0001] This invention relates to the field of double-loop fasteners for connecting ropes, specifically a double-loop fastener device for fall-prevention connecting ropes and its working method. Background Technology

[0002] Newly constructed steel pipe towers, towers over 30m, and 220kV and above line towers should be equipped with fall protection devices to prevent workers from climbing up and down the towers and moving horizontally. Towers over 80m should preferably use straight ladders or be equipped with simple rest platforms.

[0003] As a core safety equipment for high-altitude operations, the improvement of double-ring connecting ropes needs to focus on four major aspects: safety, ease of use, durability, and intelligence, while also taking into account cost and compatibility with industry standards. Typically, double-ring connecting rope devices are set with two rings, which bear the daily tension. The two rings rub against the steel beams and crossbars for a long time, and the wear points are concentrated at the edge of the opening. The rings need to be replaced every month, and the risk of single-point failure is high.

[0004] Therefore, a double-ring device for fall protection connecting ropes and its working method are proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A double-ring device for a fall arresting connecting rope, comprising a connecting rope; a first ring slidably connected to the surface of the connecting rope; a reinforcing plate fixedly connected to the surface of the connecting rope; an end of the connecting rope fixedly connected to the reinforcing plate; a movable ring slidably connected to the surface of the connecting rope; a rotating plate slidably connected to the side of the movable ring; a connecting ring fixedly connected to the side of the rotating plate; a second ring slidably connected to the inside of the connecting ring; a plurality of first threaded holes opened on the top of the reinforcing plate; and a first connecting bolt threadedly connected to the inside of the movable ring. The first connecting bolt is threaded into the first threaded hole. This step involves setting two first retaining rings to facilitate connection with fixed anchor points on the tower. By setting the first connecting bolt and the first threaded hole, the movable ring can be connected to the reinforcing plate to fix the movable ring and prevent the position of the second retaining ring from affecting the use of the first retaining rings on both sides. When the first connecting bolt separates from the first threaded hole, the second retaining ring can be moved to replace the faulty first retaining ring, allowing it to be used alternately with the first retaining ring, reducing the failure rate of the first retaining ring during use. At the same time, when the first retaining ring is damaged, it can be replaced, improving the safety and adaptability of the device.

[0007] Preferably, a second threaded hole is provided on the front side of the movable ring, and a second connecting bolt is fixedly connected to the rear side of the rotating plate. The second threaded hole is threadedly connected to the second connecting bolt. By setting the second threaded hole and the second connecting bolt, rotating the rotating plate can drive the second connecting bolt to separate from the second threaded hole, which facilitates the disassembly and assembly of the second buckle.

[0008] Preferably, a fixing block is fixedly connected to the top of the moving ring, the fixing block has a groove inside, a stud is rotatably connected inside the groove, a limit plate is threadedly connected to the surface of the stud, and both the rotating plate and the limit plate have toothed grooves on their surfaces, and the two toothed grooves cooperate to use; this step adjusts the up and down movement of the limit plate so that the toothed groove on the side of the limit plate can connect with the toothed groove on the surface of the rotating plate, thereby limiting the rotating plate and preventing the rotating plate from rotating on its own.

[0009] Preferably, the top of the reinforcing plate is fixedly connected with several positioning rods, and the bottom of the moving ring is fixedly connected with a limiting hole. The positioning rods are slidably connected to the limiting hole. This step, by setting several positioning rods and limiting holes, makes it easy for the first connecting bolt inside the moving ring to align with the first threaded hole, and at the same time prevents the moving ring from rotating after being connected to the reinforcing plate.

[0010] Preferably, an L-shaped limiting rod is rotatably connected to the side of the movable ring, and the inner side of the L-shaped limiting rod is in contact with the rotating plate. This step, by setting the L-shaped limiting rod, can limit the front side of the rotating plate after it is installed, thereby increasing the stability of the rotating plate.

[0011] Preferably, a connecting strap is fixedly connected to the surface of the connecting rope, and a safety hook is slidably connected inside the connecting strap; this step, by setting the safety hook, allows it to be connected to the installation strap, increasing the safety of the operator during use.

[0012] Preferably, a reinforcing sleeve is fixedly connected to the top of the reinforcing plate, and the end of the connecting rope is fixedly connected to the reinforcing sleeve. A wear-resistant layer is provided on the top of the reinforcing sleeve. This step of reinforcing the sleeve can increase the stability of the connection between the end of the connecting rope and the reinforcing plate. At the same time, the wear-resistant layer can reduce the friction between the connecting rope and the reinforcing sleeve.

[0013] Preferably, the surface of the connecting rope is provided with Velcro, and the surface of the Velcro is coated with a luminous coating; this step, by connecting two Velcros on one side, can limit the first buckle on one side, while making it easy for the worker to move the connecting rope on the top of the reinforcing plate on one side with one hand, and the luminous coating ensures visibility in low light environments.

[0014] A method for operating a double-loop safety rope connection device, applicable to the aforementioned double-loop safety rope connection device; the method includes:

[0015] S1: Inspection; Before use, confirm that the two second buckles and the first buckle are free from cracks and deformation, that the second buckle, the first buckle and the safety hook open and close smoothly and lock reliably, and that the rope is free from cuts, wear or chemical corrosion, and that the Velcro is sticky and undamaged.

[0016] S: In use; when the second buckle needs to be disassembled or assembled, rotate the groove to move the stud upwards, separating the toothed groove on the bottom of the stud from the toothed groove on the surface of the rotating plate. Then rotate the L-shaped limit rod to separate the inner side of the L-shaped limit rod from the front side of the rotating plate. Then rotate the rotating plate to separate the second connecting bolt from the second threaded hole, allowing the second buckle to be disassembled or assembled. Connect the safety hook to the D-ring on the safety belt and connect the two Velcro straps on one side. When climbing the tower, first connect the first buckle on one side to the nearest fixed anchor point on the tower. After connecting, pull the first buckle forcefully to test its firmness. Then connect the first buckle on the other side to the nearest fixed anchor point on the tower. Climb one... After a short distance, reach the next higher anchor point, then disconnect the first buckle and move it to a higher connection. When climbing the tower, at least one buckle must always be connected to the anchor point. It is strictly forbidden for both buckles to detach simultaneously. When the first buckle needs to be used alternately, rotate the first connecting bolt to separate it from the first threaded hole. This will unlock the moving ring, allowing it to slide on the surface of the connecting rope. The moving ring will then drive the rotating plate, connecting ring, and second buckle to move. Separate the Velcro below the first buckle that needs to be replaced on one side, allowing the moving ring to move above the Velcro. Then move the first buckle to the top of the reinforcement plate, completing the alternation of the second buckle with the first buckle on one side.

[0017] The advantages of this invention are:

[0018] 1. The anti-fall connecting rope double-ring device of the present invention, by setting two first rings, facilitates connection with fixed anchor points on the tower. By setting a first connecting bolt and a first threaded hole, a movable ring can be connected to a reinforcing plate to fix the movable ring and prevent the position of the second ring from affecting the use of the first rings on both sides. When the first connecting bolt separates from the first threaded hole, the second ring can be moved to replace the faulty first ring, so that it can be used alternately with the first ring, reducing the failure rate of the first ring during use. At the same time, when the first ring is damaged, it can be replaced, improving the safety and adaptability of the device.

[0019] 2. The anti-fall connecting rope double buckle device of the present invention, by setting a second threaded hole and a second connecting bolt, can drive the second connecting bolt and the second threaded hole to separate by rotating the rotating plate, so as to facilitate the disassembly and assembly of the second buckle.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Specific implementation examples are given below.

[0030] Please see Figures 1 to 6As shown in the embodiment of the present invention, a double-ring device for a fall arresting connecting rope includes a connecting rope 1; a first ring 12 is slidably connected to the surface of the connecting rope 1, a reinforcing plate 13 is fixedly connected to the surface of the connecting rope 1, the end of the connecting rope 1 is fixedly connected to the reinforcing plate 13, a movable ring 14 is slidably connected to the surface of the connecting rope 1, a rotating plate 15 is slidably connected to the side of the movable ring 14, a connecting ring 16 is fixedly connected to the side of the rotating plate 15, a second ring 17 is slidably connected to the inside of the connecting ring 16, a plurality of first threaded holes 18 are provided on the top of the reinforcing plate 13, a first connecting bolt 19 is threadedly connected to the inside of the movable ring 14, and the first connecting bolt 19 is threadedly connected to the first threaded holes 18; during operation, the first ring 12 is opened, and one side of the first ring 12 can be connected to the nearest fixed anchor point on the tower, and then the other side of the first ring 12 can be connected to the fixed anchor point on the tower; when the first ring 12 fails, the first connecting bolt 19 is rotated to separate it from the first threaded hole 18, and then... The movable ring 14 slides on the surface of the connecting rope 1, driving the rotating plate 15 to move, which in turn drives the connecting ring 16 to move, which in turn drives the second buckle 17 to move. The second buckle 17 can replace the first buckle 12 and is connected to the anchor point on the tower. This step, by setting two first buckles 12, facilitates connection to the fixed anchor point on the tower. By setting the first connecting bolt 19 and the first threaded hole 18, the movable ring 14 can be connected to the reinforcing plate 13 to fix the movable ring 14 and prevent the position of the second buckle 17 from affecting the use of the first buckles 12 on both sides. When the first connecting bolt 19 separates from the first threaded hole 18, the second buckle 17 can be moved to replace the faulty first buckle 12, allowing it to be used alternately with the first buckle 12, reducing the failure rate of the first buckle 12 during use. At the same time, when the first buckle 12 is damaged, it can be replaced, improving the safety and adaptability of the device.

[0031] Please see Figures 4 to 6 As shown, a second threaded hole 21 is provided on the front side of the movable ring 14, and a second connecting bolt 22 is fixedly connected to the rear side of the rotating plate 15. The second threaded hole 21 and the second connecting bolt 22 are threadedly connected. When it is necessary to disassemble or assemble the second retaining ring 17 during operation, the rotating plate 15 is rotated, which drives the second connecting bolt 22 to rotate, so that the second connecting bolt 22 is separated from the second threaded hole 21. This step, by setting the second threaded hole 21 and the second connecting bolt 22, allows the rotating plate 15 to be rotated to drive the second connecting bolt 22 to be separated from the second threaded hole 21, which facilitates the disassembly and assembly of the second retaining ring 17.

[0032] Please see Figures 4 to 6As shown, a fixing block 31 is fixedly connected to the top of the moving ring 14. A groove 32 is formed inside the fixing block 31, and a stud 33 is rotatably connected inside the groove 32. A limit plate 34 is threadedly connected to the surface of the stud 33. Both the rotating plate 15 and the limit plate 34 have toothed grooves on their surfaces, and the two toothed grooves cooperate. During operation, when the rotating plate 15 drives the second connecting bolt 22 to connect with the second threaded hole 21, the stud 33 is rotated, causing it to move the limit plate 34 upwards. Then, the rotating plate 15 can... The second connecting bolt 22 is fully connected to the second threaded hole 21 until the side of the rotating plate 15 is in contact with the moving ring 14. Then, the stud 33 is rotated to drive the limiting plate 34 to move down. The toothed groove on the side of the limiting plate 34 connects with the toothed groove on the surface of the rotating plate 15 to limit the rotation plate 15. This step is achieved by adjusting the up and down movement of the limiting plate 34 so that the toothed groove on the side of the limiting plate 34 can connect with the toothed groove on the surface of the rotating plate 15 to limit the rotation plate 15 and prevent the rotating plate 15 from rotating on its own.

[0033] Please see Figures 5 to 6 As shown, the top of the reinforcing plate 13 is fixedly connected with several positioning rods 41, and the bottom of the moving ring 14 is fixedly connected with a limiting hole 42. The positioning rods 41 and the limiting hole 42 are slidably connected. During operation, when the moving ring 14 is connected to the reinforcing plate 13, the positioning rods 41 are connected to the limiting hole 42. This step, by setting several positioning rods 41 and limiting holes 42, makes it easy for the first connecting bolt 19 inside the moving ring 14 to align with the first threaded hole 18, and at the same time prevents the moving ring 14 from rotating after being connected to the reinforcing plate 13.

[0034] Please see Figures 5 to 6 As shown, an L-shaped limiting rod 51 is rotatably connected to the side of the moving ring 14, and the inner side of the L-shaped limiting rod 51 is in contact with the rotating plate 15. During operation, when the rotating plate 15 is connected to the moving ring 14, the L-shaped limiting rod 51 is rotated so that its inner side is in contact with the surface of the rotating plate 15. When the rotating plate 15 is removed, the L-shaped limiting rod 51 is reversed so that its inner side is separated from the rotating plate 15. This step, by setting the L-shaped limiting rod 51, can limit the front side of the rotating plate 15 after installation, thereby increasing the stability of the rotating plate 15.

[0035] Please see Figures 1 to 4 As shown, a connecting strap 61 is fixedly connected to the surface of the connecting rope 1, and a safety hook 62 is slidably connected inside the connecting strap 61. During operation, the safety hook 62 is opened and connected to the D-ring on the safety belt. This step, by setting the safety hook 62, allows it to be connected to the installation belt, increasing the safety of the operator during use.

[0036] Please see Figures 1 to 4As shown, a reinforcing sleeve 71 is fixedly connected to the top of the reinforcing plate 13, and the end of the connecting rope 1 is fixedly connected to the reinforcing sleeve 71. A wear-resistant layer is provided on the top of the reinforcing sleeve 71. This step of reinforcing sleeve 71 can increase the stability of the connection between the end of the connecting rope 1 and the reinforcing plate 13. At the same time, the wear-resistant layer can reduce the friction between the connecting rope 1 and the reinforcing sleeve 71.

[0037] Please see Figures 1 to 4 As shown, the surface of the connecting rope 1 is provided with Velcro 81, and the surface of the Velcro 81 is coated with a luminous coating. During operation, the two Velcro 81 on one side of the connecting rope 1 can be connected to limit the first buckle 12 on the surface of the connecting rope 1. When the moving ring 14 replaces the first buckle 12, the two Velcro 81 are separated. This step, by connecting the two Velcro 81 on one side, can limit the first buckle 12 on one side, and at the same time, it is convenient for the operator to hold the connecting rope 1 on the top of the reinforcing plate 13 on one side with one hand and move it. The luminous coating ensures visibility in low light environments.

Connect the safety hook 62 to the D-ring on the safety belt and connect the two Velcro straps 81 on one side. When climbing the tower, first connect the first buckle 12 on one side to the nearest fixed anchor point on the tower. After connecting, pull the first buckle 12 forcefully to test its firmness. Then connect the first buckle 12 on the other side to the nearest fixed anchor point on the tower.

When climbing the tower, at least one buckle must always be connected to the anchor point. It is strictly forbidden for both buckles to detach at the same time. When the first buckle 12 needs to be used alternately, rotate the first connecting bolt 19 to separate it from the first threaded hole 18. This will unlock the moving ring 14, allowing it to slide on the surface of the connecting rope 1. The moving ring 14 will drive the rotating plate 15, the connecting ring 16, and the second buckle 17 to move. Separate the Velcro 81 below the first buckle 12 that needs to be replaced on one side, allowing the moving ring 14 to move above the Velcro 81. Then move the first buckle 12 to the top of the reinforcing plate 13, completing the alternation of the second buckle 17 with the first buckle 12 on one side.

[0041] Working principle: When the second buckle 17 needs to be disassembled or assembled, rotate the groove 32 to move the stud 33 upward. The toothed groove on the bottom surface of the stud 33 separates from the toothed groove on the surface of the rotating plate 15. Then rotate the L-shaped limiting rod 51 to separate the inner side of the L-shaped limiting rod 51 from the front side of the rotating plate 15. Then rotate the rotating plate 15 to separate the second connecting bolt 22 from the second threaded hole 21, allowing the second buckle 17 to be disassembled or assembled. Connect the safety hook 62 to the D-ring on the safety belt and connect the two Velcro straps 81 on one side. When climbing the tower, first connect the first buckle 12 on one side to the nearest fixed anchor point on the tower. After connecting, pull the first buckle 12 forcefully to test its firmness. Then connect the first buckle 12 on the other side to the nearest fixed anchor point on the tower. Climb a small... After a short distance, reach the next higher anchor point, then disconnect the first first buckle 12 and move it to a higher connection. When climbing the tower, at least one buckle must always be connected to the anchor point. It is strictly forbidden for both buckles to detach at the same time. When the first buckle 12 needs to be used alternately, rotate the first connecting bolt 19 to separate it from the first threaded hole 18. This will unlock the moving ring 14, allowing it to slide on the surface of the connecting rope 1. The moving ring 14 will drive the rotating plate 15, the connecting ring 16, and the second buckle 17 to move. Separate the Velcro 81 below the first buckle 12 that needs to be replaced on one side, allowing the moving ring 14 to move above the Velcro 81. Then move the first buckle 12 to the top of the reinforcing plate 13, completing the alternation of the second buckle 17 with the first buckle 12 on one side.
