[0020] 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.

[0021] like Figures 1-7 The image shows an embodiment of the anti-vibration hammer structure for overhead cables according to the present invention.

[0022] In this embodiment, the vibration damper structure for overhead cables includes: a base 1; a clamping assembly 2 mounted on the base 1 for clamping the overhead cable 3; a reinforcing assembly 4 connected to the base 1; spacing adjustment assemblies 5 respectively mounted on opposite sides of the reinforcing assembly 4; and a vibration damper body 6 detachably connected to the end of the spacing adjustment assembly 5.

[0023] The spacing adjustment assembly 5 includes: an adjustment seat 51, two bearing rings 52 installed at opposite ends of the adjustment seat 51, a lead screw 53 connected between the two bearing rings 52, a guide rod 54 located in the adjustment seat 51, a slider seat 56 meshing with the lead screw 53, and a positioning shaft tube 58 fastened to the slider seat 56, wherein: the guide rod 54 is located on one side of the lead screw 53 and passes through the slider seat 56, and the anti-vibration hammer body 6 is connected to the positioning shaft tube 58.

[0024] The drive screw 53 rotates, causing the slider seat 56 to slide along the screw 53 under the guidance of the guide rod 54. The lateral distance between the two anti-vibration hammer bodies 6 is adjusted in conjunction with the positioning shaft tube 58 to suppress the swaying and vibration of the overhead cable under the influence of external vibration.

[0025] In specific implementation, the vibration damper body 6 of this application is connected and assembled one-to-one with the two sets of vibration damper bodies 6 through the two sets of spacing adjustment components 5, so that the two sets of vibration damper bodies 6 can be adjusted one-to-one in the lateral spacing on the two sets of spacing adjustment components 5, thereby realizing the adjustment of the hammer head spacing on both sides of the base 1.

[0026] At the same time, by increasing the distance between the hammer heads of the two sets of anti-vibration hammer bodies 6, the anti-vibration effect of the anti-vibration hammer body 6 can be improved, enabling it to better suppress the swaying and vibration of the overhead cable 3 under external vibrations such as wind vibration, and protect the safety of the overhead cable 3 and related equipment.

[0027] In specific implementation, in order to adjust the spacing between the two sets of anti-vibration hammer bodies 6, so as to realize the anti-vibration use of the anti-vibration hammer bodies 6 under different hammer head spacing, so as to adapt to the anti-vibration requirements of overhead cables 3 of different diameters, the spacing adjustment component 5 is set as follows.

[0028] The spacing adjustment assembly 5 includes: an adjustment seat 51, two bearing rings 52 installed at opposite ends of the adjustment seat 51, a lead screw 53 connected between the two bearing rings 52, a guide rod 54 located in the adjustment seat 51, a slider seat 56 meshing with the lead screw 53, and a positioning shaft tube 58 fastened to the slider seat 56, wherein: the guide rod 54 is located on one side of the lead screw 53 and passes through the slider seat 56, and the anti-vibration hammer body 6 is connected to the positioning shaft tube 58.

[0029] Furthermore, the slider seat 56 and the positioning shaft tube 58 are fixedly connected by the mounting seat 57; the anti-vibration hammer body 6 includes: a rocker arm 61 and an anti-vibration hammer head 62 connected to the side of the rocker arm 61, and the rocker arm 61 is detachably connected to the positioning shaft tube 58.

[0030] In practice, the adjusting seat 51 is located on the side of one of the limiting baffles 45. Both ends of the adjusting seat 51 are equipped with bearing rings 52, and a lead screw 53 is rotatably provided between the two bearing rings 52. Slider seats 56 are meshed on the outside of the two lead screws 53, and mounting seats 57 are installed on the sides of the two slider seats 56. The spacing adjusting assembly 5 also includes two guide rods 54 disposed in the adjusting seat 51. The two guide rods 54 are respectively disposed on one side of the lead screw 53 and simultaneously pass through the slider seats 56.

[0031] To facilitate the connection and installation of the spacing adjustment component 5 and the anti-vibration hammer body 6, in a preferred embodiment, the spacing adjustment component 5 further includes a positioning shaft tube 58 integrally disposed on the side of the mounting base 57.

[0032] The rocker arm 61 has a connecting thread 63 at its end, and the positioning shaft tube 58 has an internal thread that matches the connecting thread 63. The rocker arm 61 is threadedly connected to the positioning shaft tube 58. The threaded connection between the rocker arm 61 and the positioning shaft tube 58 allows the user to install the anti-vibration hammer body 6 quickly and easily, while also making the operation simple.

[0033] The purpose of this setting is to consider that when cables of different diameters are affected by wind vibration, the amplitude of the anti-vibration hammer body 6 needs to be larger. Therefore, in the preferred embodiment, in addition to adjusting the distance between the two sets of anti-vibration hammer bodies 6, the user can also use the threaded connection of the positioning shaft tube 58 and the rocker arm 61 to quickly replace the connecting threads 63 of different sizes, so as to better adapt to the wind vibration resistance of overhead cables 3 of different diameters.

[0034] In practical implementation, the user rotates the lead screw 53. When the lead screw 53 rotates, it is laterally limited by the two guide rods 54. At this time, the slider seat 56, which is engaged with the outside of the lead screw 53, will move linearly left and right along the stroke range of the lead screw 53. This will drive the mounting seat 57 and the positioning shaft tube 58 on the side of the slider seat 56 to move synchronously. At this time, through the connection between the positioning shaft tube 58 and the anti-vibration hammer body 6, the anti-vibration hammer body 6 can move linearly along the stroke range of the lead screw 53, thereby realizing the adjustment of the hammer head spacing between the two anti-vibration hammer bodies 6.

[0035] Preferably, one end of the lead screw 53 passes through the adjusting seat 51 and is connected to a rotating handle 55, and the rotating handle 55 is covered with an anti-static rubber sleeve.

[0036] The purpose of this design is to improve the rotation efficiency of the lead screw 53 and facilitate its rotation. In actual use, when the user rotates the shaft handle 55, the lead screw 53 connected to it will rotate accordingly. The anti-static sleeve fitted over the shaft handle 55 effectively prevents the accumulation of static electricity, reducing the impact of electrostatic discharge on the equipment and operators, and improving operational safety. Furthermore, the sleeve provides additional comfort and grip, making it more comfortable for the operator to use the shaft handle 55 and reducing hand fatigue.

[0037] Furthermore, the reinforcement component 4 includes: two mounting bases 41, two limiting baffles 45 correspondingly disposed on the two opposite outer sides of the two mounting bases 41, and a double-ended threaded post 44. The two ends of the double-ended threaded post 44 pass through one of the adjacent mounting bases 41 and are threadedly connected to a limiting baffle 45.

[0038] Among them, side seats 11 are fastened to opposite sides of the base 1, the side seats 11 are fastened to an adjacent assembly seat 41, and the side seats 11 are fastened to an adjacent limiting baffle 45; the adjusting seat 51 is fastened to a limiting baffle 45.

[0039] Each mounting base 41 is equipped with a nut washer on its inner side. One end of the double-threaded post 44 passes through the nut washer and is fastened on the outside by a nut 43. Each mounting base 41 is provided with a positioning hole 42 on its side. The mounting base 41 is fastened to the side seat 11 by bolt connection.

[0040] The function of reinforcing component 4 is to strengthen the elongation between the two sets of spacing adjustment components 5. During implementation,

[0041] Two mounting seats 41 are provided on the lower end face of the base 1, and a double-ended threaded post 44 is inserted between the two mounting seats 41. Both ends of the double-ended threaded post 44 pass through one of the adjacent mounting seats 41 and are threadedly connected to a limit baffle 45. Nut washers are installed in both mounting seats 41. The double-ended threaded post 44 passes through the washers and is threadedly connected to a nut 43. The nut 43 is tightly abutted against the side of the adjacent mounting seat 41. Positioning holes 42 are pre-set on the side of both mounting seats 41. Side seats 11 are protruding on both the left and right sides of the base 1. The positioning holes 42 fit with the side seats 11 and bolts are threaded between them.

[0042] Meanwhile, when the user installs the reinforcement component 4, the mounting base 41 is aligned with the two side seats 11 so that they fit together, and then bolts are used to pass through the positioning holes 42 and the side seats 11 to achieve the connection and installation of the side seats 11 and the mounting base 41.

[0043] Furthermore, the user assembles the double-ended threaded post 44 on the mounting base 41 by passing both ends of the double-ended threaded post 44 through the two mounting bases 41 in sequence, and uses the limiting baffle 45 to assemble the double-ended threaded post 44 on the mounting base 41. Then the user places the limiting baffle 45 on the side of the double-ended threaded post 44 to connect the two.

[0044] Preferably, considering the portability for outdoor operations, the limiting baffle 45 and the double-ended threaded post 44 are connected by threads. In the actual design, the limiting baffle 45 has a threaded hole on its side that cooperates with the threaded part at the end of the double-ended threaded post 44, thereby realizing the assembly of the double-ended threaded post 44 and the limiting baffle 45.

[0045] In this embodiment, in order to further improve the installation stability of the limiting baffle 45, in the preferred embodiment, the side of the limiting baffle 45 and the side of the adjacent side seat 11 are provided with internal hexagonal thread holes, so that the user can use internal hexagonal bolts to realize the threaded connection between the two.

[0046] Meanwhile, in order to further improve the connection stability between the reinforcement component 4 and the spacing adjustment component 5, in a preferred embodiment, the two limiting baffles 45 are fitted with one of the adjacent side seats 11 and are threadedly connected with hexagonal bolts.

[0047] Furthermore, a bird deterrent assembly 7 is installed on the side of the base 1. The bird deterrent assembly 7 includes: a rotating shaft 71 connected to the side of the base 1, a bearing ring mounted on the rotating shaft 71, a rotating ring 72 sleeved on the bearing ring, and several connecting arms 73 connected to the rotating ring 72.

[0048] Preferably, a plurality of connecting arms 73 are evenly arranged around the outer side of the rotating ring 72 along its center.

[0049] The function of the bird deterrent component 7 is as follows: Considering that the vibration damper body 6 will shake during outdoor use, thereby attracting flying animals such as birds, by setting the bird deterrent component 7, the birds will be scared away, reducing their stay near the vibration damper, thereby reducing the damage and pollution caused by birds to the vibration damper body 6. At the same time, the probability of birds staying and foraging on the spacing adjustment component 5 and the vibration damper body 6 of this application can be reduced, thereby reducing the damage and pollution to the equipment, extending the service life of the equipment, and reducing maintenance costs.

[0050] In practice, the bird deterrent assembly 7 includes a rotating shaft 71 disposed on the side of the base 1. A bearing ring is fitted on the outside of the rotating shaft 71, and a rotating ring 72 is sleeved on the outside of the bearing ring. Several connecting arms 73 are arranged around the outside of the rotating ring 72 along its center. A reflector 74 is installed at the other end of each connecting arm 73.

[0051] In this embodiment, the assembly between the rotating shaft 71 and the bearing ring allows the rotating ring 72 to rotate outside the rotating shaft 71, thereby driving several connecting arms 73 and reflectors 74 to rotate freely.

[0052] Preferably, each connecting arm 73 is equipped with a reflector 74. The reflector 74 can reflect light in sunlight to create a shimmering effect.

[0053] In this embodiment, when the user needs to install the vibration damper body 6, the end of the rocker arm 61 is aligned with the positioning shaft tube 58, and then the connecting thread 63 is threaded into the positioning shaft tube 58 to achieve the connection of the rocker arm 61 into the positioning shaft tube 58. By installing the two rocker arms 61, the user can assemble the vibration damper body 6 onto the two positioning shaft tubes 58, thereby enabling the two sets of vibration damper bodies 6 to be assembled on the spacing adjustment component 5 for vibration damping.

[0054] Next, the user assembles the clamp assembly 2 onto the outside of the overhead cable 3 and uses bolts to complete the connection between 2 and the overhead cable 3. At this time, by connecting the reinforcement assembly 4 set on the side of the base 1 and the two sets of spacing adjustment assemblies 5, the two sets of anti-vibration hammer bodies 6 can be used to assist in vibration damping at the bottom of the overhead cable 3, thereby reducing the amplitude of the overhead cable 3 when subjected to wind vibration.

[0055] When the diameter of the overhead cable 3 changes, the user can adjust the distance between the two anti-vibration hammers 62, thereby adjusting the amplitude of the two rocker arms 61 to adapt to the change in the diameter of the overhead cable 3.

[0056] During this period, the user rotates the two rotating handles 55. When the handles 55 rotate, the lead screw 53 connected to them will also rotate. When the lead screw 53 rotates, it is laterally limited by the two guide rods 54. At this time, the slider seat 56 engaged with the outside of the lead screw 53 will move linearly left and right along the stroke range of the lead screw 53, thereby driving the mounting seat 57 and the positioning shaft tube 58 on the side of the slider seat 56 to move synchronously. When the distance between the two positioning shaft tubes 58 decreases, the distance between the two anti-vibration hammers 62 is shortened, and the overall amplitude is reduced, thus adapting to the overhead cable 3 with a smaller diameter. When the distance between the two positioning shaft tubes 58 increases, the amplitude distance between the two swing rods 61 increases, thus allowing the overhead cable 3 with a larger diameter to be used for wind vibration resistance.

[0057] The present invention provides a vibration damper structure for overhead cables, which has the following advantages: The vibration damper structure for overhead cables includes: a base; a clamping assembly mounted on the base for clamping overhead cables; a reinforcing assembly connected to the base; spacing adjustment assemblies respectively mounted on opposite sides of the reinforcing assembly; and a vibration damper body detachably connected to the end of the spacing adjustment assembly, wherein: the spacing adjustment assembly includes: an adjustment seat, two bearing rings mounted on opposite ends of the adjustment seat, a lead screw connected between the two bearing rings, and a guide rod disposed within the adjustment seat. The device consists of a slider seat meshing with a lead screw and a positioning shaft tube fastened to the slider seat. A guide rod is located on one side of the lead screw and passes through the slider seat. The anti-vibration hammer body is connected to the positioning shaft tube. The drive screw rotates, causing the slider seat to slide along the lead screw under the guidance of the guide rod. The lateral distance between the two anti-vibration hammer bodies is adjusted via the positioning shaft tube to suppress the swaying and vibration of overhead cables under external vibration. The spacing between the hammer heads can be adjusted to adapt to the wind-vibration resistance of cables of different diameters. The device has a simple structure and a wide range of applications.
