Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration hammers, in particular to an anti-vibration hammer for high-voltage power transmission lines. Background Art

[0002] The anti-vibration hammer is designed to reduce the vibration of high-voltage transmission lines caused by wind. The pole position of high-voltage overhead lines is high and the span is large. When the high-voltage transmission lines are affected by wind, vibrations will occur. Multiple vibration lines will cause fatigue damage to the high-voltage transmission lines due to periodic bending. Therefore, when the overhead line span is greater than 120 meters, an anti-vibration hammer is generally used for vibration prevention. Traditional anti-vibration hammers for high-voltage transmission lines usually use screws to fasten the wire clamps and cover plates of the corresponding clamped conductors together. However, with the passage of time and the influence of bad weather, the screws of the anti-vibration hammers installed in this way often loosen, resulting in the risk of the anti-vibration hammer falling from a height and injuring passers-by. Therefore, application number: 202121790791.4 discloses an anti-vibration hammer for high-voltage transmission lines, which can pull the falling anti-vibration hammer by setting a steel wire rope, which can effectively reduce the risk of the anti-vibration hammer falling and injuring people;

[0026] Working principle: When in use, the anti-vibration hammer body and the high-voltage transmission line 102 are in an uninstalled state. When installing, the U-shaped mounting seat 2 is sleeved on the high-voltage transmission line 102, and when the bottom of the high-voltage transmission line 102 contacts the top of the elastic anti-slip rubber 5 below, the pull ring is pulled downward to drive the L-shaped limit rod 17 to move downward, and the L-shaped limit rod 17 drives the second magnet 18 downward to separate from the first magnet, releasing the lateral fixation of the L-shaped limit rod 17, and then the L-shaped limit rod 17 can be pushed to the right, and the L-shaped limit rod 17 drives the moving rod 15 to slide to the right on the second guide rod 14, and the moving rod 15 compresses the spring 16 while moving to the right, and the moving rod 15 drives the clamping rod 12 to move from the clamping slot 11 in turn. And one of the card holes 10 is moved out, and the vertical fixation of the first guide rod 9 is released. At this time, the first guide rod 9 can be moved downward. The first guide rod 9 drives the second clamping plate 4 to move downward through the pressure sensor 8. When the second clamping plate 4 drives the elastic anti-skid rubber 5 above to move downward until it contacts the top of the high-voltage transmission line 102, the first guide rod 9 that continues to move downward drives the pressure sensor 8 to squeeze the second clamping plate 4 downward. The second clamping plate 4 squeezes the elastic anti-skid rubber 5, so that the elastic anti-skid rubber 5 is deformed and fits tightly with the high-voltage transmission line 102. At the same time, the pressure sensor 8 detects the squeezing force and transmits the detected pressure value to the controller 6. When the pressure value reaches the preset value, the controller 6 controls The sound and light alarm 7 emits a sound and light alarm to remind the personnel. At this time, the personnel stops moving the first guide rod 9 downward. If there is a slight deviation between one of the card holes 10 and the card rod 12, the first guide rod 9 can continue to be slightly moved downward. When one of the card holes 10 is aligned with the card rod 12, the rightward thrust of the L-shaped limit rod 17 is relaxed. At this time, the elastic force of the spring 16 in the compressed state drives the moving rod 15 to move to the left, and the moving rod 15 drives the L-shaped limit rod 17 and the card rod 12 to move to the left. The card rod 12 moves to the left into one of the card holes 10 and the card slot 11, thereby realizing the vertical restriction of the first guide rod 9, and then moves the L-shaped limit rod 17 upward, and the L-shaped limit rod 17 drives the second magnet 18 to move upward to the recessed The first magnet is in the groove and adsorbed with the bottom of the first magnet to realize the lateral restriction of the L-shaped limit rod 17, thereby realizing the lateral restriction of the moving rod 15 and the clamping rod 12. At this time, the anti-vibration hammer body is connected and fixed with the high-voltage transmission line 102 through the clamping force of the first clamping plate 3, the second clamping plate 4 and the elastic anti-slip rubber 5, and the position of the second clamping plate 4 can be effectively fixed by clamping and fixing in combination with the vertical and lateral restriction methods, thereby realizing the stable fixation between the anti-vibration hammer body and the high-voltage transmission line 102. The clamping and fixing method can effectively avoid the loosening of the anti-vibration hammer body due to the loosening of the vibration force thread, thereby fundamentally solving the risk of the anti-vibration hammer body falling and improving the fixing stability.

[0027] After the entire device is fixed, the personnel turn off the sound and light alarm 7, and use the controller 6 to preset the pressure value for controlling the sound and light alarm 7 to open in the use state. When the anti-vibration hammer body accidentally falls off, its high-voltage transmission line 102 will move out from the two elastic anti-slip rubbers 5, and then the squeezing force of the elastic anti-slip rubbers 5 on the high-voltage transmission line 102 disappears. When the pressure sensor 8 detects that its squeezing force is lower than the preset value, the controller 6 controls the sound and light alarm 7 to send out a sound and light alarm to remind the personnel to avoid the position below. By reminding the personnel to avoid it, the risk of the anti-vibration hammer body falling and injuring personnel can be effectively reduced. In addition, the controller 6 also sends it to the external monitoring terminal through the wireless sending module, which is convenient for the personnel to know and deal with it in time, thereby improving the timeliness of the personnel's knowledge.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
