Description

Technical Field

[0001] The present invention relates to the technical field of transmission line maintenance, and particularly to an anti-slip and anti-falling soft ladder head for high-altitude maintenance of conductors and ground wires. Background Art

[0002] In the high-altitude construction and maintenance operations of overhead transmission lines, workers often use a soft ladder to enter the conductors and ground wires for high-altitude maintenance, defect elimination, etc., which is a commonly used operation method. The entire soft ladder consists of a metal soft ladder head and soft ladder ropes, and the soft ladder head and the soft ladder ropes are connected by a grasshopper buckle. The closing door of the soft ladder head can prevent the soft ladder head from slipping off the conductor and plays a protective role. The closing door of the soft ladder head of the traditional soft ladder is a semi-circular metal ring with a hole at each end. Closing the door hook requires the worker to climb onto the conductor and directly lock it by hand to close the door.

[0003] When performing live work on the conductor, the soft ladder head is transferred to the conductor by an insulating transfer rope, and then the wire wheel of the soft ladder head is hung on the conductor. During this process, only after the equipotential operator climbs along the soft ladder to the soft ladder head can the operation of closing the closing door of the soft ladder head be carried out. When the worker climbs the soft ladder, due to the movement of the human body and the influence of the on-site working terrain and towers, etc., the conductor will vibrate up and down and the soft ladder will sway left and right. Since there is no closing door at the upper end of the soft ladder head, it is extremely easy for the wire wheel of the soft ladder head to fall off the conductor, causing the soft ladder to fall from a high altitude, thus resulting in a high-altitude fall accident for the high-altitude operator climbing the soft ladder.

[0004] When performing live defect elimination on the conductor, since the conductors have a certain height difference, it is more convenient for the wire wheel to slide on the conductor. However, there is no fixed braking and anti-slip braking device. When repairing the conductor, replacing the vibration damper, or replacing the spacer at a specific position on the conductor, it is necessary to fix oneself first and then start working, which is time-consuming and laborious and increases the operation risk of high-altitude operators.

Specific implementation mode

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1-3 shown, the present invention is an anti-slip and anti-falling soft ladder head for high-altitude maintenance of ground wires and overhead lines.

[0026] In order to further ensure that the distance between the load-bearing connecting pieces 7 does not change due to the force on the ladder head body 1, a load-bearing U-ring 24 is also arranged at the top opening of the two parallel load-bearing vertical rods 5. The load-bearing U-ring 24 is an arc-shaped rod body, and its two ends are inserted into the bottom of the load-bearing connecting piece 7 and fixedly connected with the load-bearing connecting piece 7.

[0027] Specific structure of the brake lock component:

[0028] As Figure 4-6 shown, the brake lock assembly 3 is composed of a swing frame 9 and an abutting block 10. The swing frame 9 is a frame structure, integrally in a Y shape. There is a first groove 11 at the middle of the Y-shaped opening of the swing frame 9, and it is rotationally connected to the hanging component 2 through the first groove 11. Second grooves 12 are respectively provided on the frame bodies on both sides of the Y-shaped opening of the swing frame 9, and are rotationally connected to the abutting block 10 through the second grooves 12. The bottom of the swing frame 9 is an operating rod 13, and by swinging the operating rod 13 downward, the frame bodies on both sides of the Y-shaped opening and the abutting block 10 can swing upward to cooperate with the arc groove of the wire walking pulley 8 to abut against the ground wire. The operating rod 13 is a hollow tube body. One end of the operating rod 13 extends into the first groove 11, and a positioning component is provided in the operating rod 13 and the first groove 11. The positioning component is composed of a button 14, a return spring 15, a first built-in connecting rod 16, a second built-in connecting rod 17 and a special-shaped toothed plate 18. The special-shaped toothed plate 18 is arranged in the first groove 11. One end of the special-shaped toothed plate 18 is fixedly connected to the hanging component 2, and the other end is an arc surface, and several teeth are provided on the arc surface. The first built-in connecting rod 16 is a plate body, located in the first groove 11. The middle of the first built-in connecting rod 16 is rotationally connected to the first groove 11 through a pin shaft. One end of the first built-in connecting rod 16 can be caught in the teeth of the special-shaped toothed plate 18, and the other end is rotationally connected to the second built-in connecting rod 17. The second built-in connecting rod 17 is located in the operating rod 13 and can slide in the operating rod 13. One end of the second built-in connecting rod 17 is rotationally connected to the button 14. The button 14 is located at the end of the operating rod 13 and part of it is exposed outside the operating rod 13. A return spring 15 that can abut against the inner wall of the operating rod 13 is provided on the button 14.

[0029] Specific structure of the anti-falling component:

[0030] As Figure 7-8 shown, the anti-falling component 4 is composed of a self-locking tongue frame 19, a special-shaped adjusting connecting rod 20 and a telescopic load-bearing vertical rod 21. The side of the self-locking tongue frame 19 is wedge-shaped, and the top surface is H-shaped. Long openings and short openings are respectively provided at both ends of the self-locking tongue frame 19, and are rotationally connected to the hanging component 2 and the special-shaped adjusting connecting rod 20 through the long openings respectively. The bottom of the special-shaped adjusting connecting rod 20 is threadedly connected to the telescopic load-bearing vertical rod 21, and the length can be adjusted by the thread. The special-shaped adjusting connecting rod 20 is rotationally connected to the load-bearing connecting piece 7 through the telescopic load-bearing vertical rod 21. The telescopic load-bearing vertical rod 21, the special-shaped adjusting connecting rod 20, the self-locking tongue frame 19 form a linkage with the hanging component 2 and the load-bearing connecting piece 7. When the hanging component 2 moves vertically upward to the maximum position, the self-locking tongue frame 19 closes the bottom opening of the hook body of the hanging component 2 through the short opening.

[0031] Installation and use process:

[0032] When installing the anti-slip and anti-falling soft ladder head for high-altitude maintenance of the conductor and ground wire, first, the high-altitude operator passes the traction rope through the tumbler pulley and hangs the tumbler pulley on the conductor and ground wire. The ground personnel connect the bottoms of the two load-bearing vertical rods 5 of the ladder head body 1 to the soft ladder rope. Then, the ground cooperation personnel use the traction rope to tow the soft ladder head body 1 and the soft ladder rope to the conductor, and hang the entire anti-slip and anti-falling soft ladder head for high-altitude maintenance of the conductor and ground wire on the conductor through the hanging component 2, and ensure that the conductor is located in the arc groove of the wire running pulley 8 inside the hook body. During the hanging process of the hanging component 2 and the conductor, due to the influence of the gravity of the ladder head body 1 and the soft ladder rope on the hanging component 2, the ladder head body 1 and the load-bearing connecting piece 7 move downward relative to the hanging component 2, and the hanging component 2 moves vertically upward in the cavity 22 of the load-bearing connecting piece 7 until the anti-detachment plate 23 at the bottom of the hanging component 2 abuts against the top surface of the cavity 22 of the load-bearing connecting piece 7, forming a falling self-locking door. The ground personnel can climb to the conductor through the soft ladder rope and carry out maintenance work on the conductor.

[0033] After the work is completed, the high-altitude personnel climb down to the ground from the conductor through the soft ladder rope. During the removal process, due to the upward pulling force on the traction rope, the soft ladder head body 1 and the soft ladder rope are subjected to an upward force, and the ladder head body 1 and the load-bearing connecting piece 7 move upward relative to the hanging component 2. The hanging component 2 moves vertically downward in the cavity 22 of the load-bearing connecting piece 7 until the anti-detachment plate 23 at the bottom of the hanging component 2 disengages from the top surface of the cavity 22 of the load-bearing connecting piece 7, forming an upward lifting automatic unlocking. The ground cooperation operation lowers the ladder head body 1 and the soft ladder rope to the ground, and then removes the traction rope and the tumbler pulley.

[0034] Working principle of the anti-falling component:

[0035] During the hanging process of the above-mentioned anti-slip and anti-falling soft ladder head for high-altitude maintenance of the conductor and ground wire, the anti-falling component 4 on the hanging component 2 acts. The telescopic load-bearing vertical rod 21, the special-shaped adjusting connecting rod 20, and the self-locking tongue frame 19 of the anti-falling component 4 form a linkage with the hanging component 2 and the load-bearing connecting piece 7. When the hanging component 2 moves vertically upward to the maximum position, the telescopic load-bearing vertical rod 21 moves downward with the load-bearing connecting piece 7. The telescopic load-bearing vertical rod 21 moves downward and pulls the long opening end of the self-locking tongue frame 19 to swing downward through the special-shaped adjusting connecting rod 20. Since the self-locking tongue frame 19 is rotationally connected to the hanging component 2 through the long opening, while the special-shaped adjusting connecting rod 20 pulls the self-locking tongue frame 19 to swing downward, the short opening of the self-locking tongue frame 19 swings upward to close the bottom opening of the hook body of the hanging component 2, thereby preventing the conductor from detaching from the hook body of the hanging component 2. At this time, the high-altitude personnel can climb to the ladder head body 1 through the soft ladder rope for high-altitude construction and maintenance operations.

[0036] Working principle of the brake lock component:

[0037] When using this anti-slip and anti-falling soft ladder head for high-altitude maintenance of ground wires to carry out high-altitude construction and maintenance operations on overhead transmission lines, due to the certain height difference of the ground wires, it is relatively convenient for the wire wheels to slide on the ground wires. When repairing the ground wires, replacing the vibration dampers, or replacing the spacer dampers at a specific position on the ground wires, the high-altitude personnel can position this anti-slip and anti-falling soft ladder head for high-altitude maintenance of ground wires through the brake lock assembly 3. When positioning is required, first, the high-altitude personnel press the button 14 of the positioning assembly. The button 14 compresses the return spring 15 and can drive the second internal link 17 to slide towards one end of the first groove body 11 in the operating rod 13 at the same time. While the second internal link 17 slides towards one end of the first groove body 11, the second internal link 17 can drive the first internal link 16 to swing, making one end of it disengage from the teeth of the special-shaped tooth plate 18. At this time, the operating rod 13 of the brake lock assembly 3 can be pressed downwards. While pressing down the operating rod 13, the frame bodies on both sides of the Y-shaped opening of the swing frame 9 and the abutting blocks 10 on the second groove body 12 swing upwards, so that the abutting blocks 10 cooperate with the arc grooves of the wire wheels 8 to abut against the ground wires. After the abutting blocks 10 cooperate with the arc grooves of the wire wheels 8 to abut against the ground wires, release the button 14. The button 14 resets under the action of the return spring 15. At the same time, the button 14 can drive the second internal link 17 to slide towards the button 14 end in the operating rod 13. While the second internal link 17 slides towards one end of the first groove body 11, the second internal link 17 can drive the first internal link 16 to swing, making one end of it snap into the teeth of the special-shaped tooth plate 18 to form a positioning.

[0038] In order to facilitate the use of this anti-slip and anti-falling soft ladder head for high-altitude maintenance of ground wires to quickly move from the lower part of the ground wire to the upper part during high-altitude construction and maintenance operations on overhead transmission lines, an external connection ring 28 is also provided at the top of any one of the hanging components 2 connected to the tops of the two parallel load-bearing vertical rods 5. Through the external connection ring 28, ropes and pulleys can be connected. By pulling the connecting rope, this anti-slip and anti-falling soft ladder head for high-altitude maintenance of ground wires can quickly move from the lower part of the ground wire to the upper part, thus saving the physical energy of high-altitude personnel.

[0039] In order to enable high-altitude personnel to sit on the ladder head body 1 for high-altitude construction and maintenance operations. A load-bearing sitting ring 26 is also provided at the top between the two parallel load-bearing vertical rods 5. The two ends of the load-bearing sitting ring 26 are respectively rotatably connected to the load-bearing vertical rods 5 through sitting ring connectors 27, and the maximum rotation angle is 90°. In addition, in order to ensure the safety of high-altitude personnel, a rope connection anti-slip positioning auxiliary ring 25 is also provided on the load-bearing U-ring 24. Through the rope connection anti-slip positioning auxiliary ring 25, it can be hooked to the safety hanging rope on the body of high-altitude personnel.
