Description
Technical Field
[0001] This utility model relates to the field of vibration damper technology, specifically an adjustable fixing mechanism for vibration dampers on power transmission line conductors. Background Technology
[0002] A transmission line conductor vibration damper is a device used to protect transmission line conductors from damage caused by light wind vibrations. It is typically fixed to the conductor using claw clamps.
[0003] After prolonged use, vibration dampers are subjected to continuous wind vibration, causing the damper body to slowly slip along the tangential direction of the conductor, thus affecting its vibration damping effect. Maintenance personnel need to periodically reset the dampers; however, the original clamping points are deformed or worn due to long-term clamping, and the jaws cannot effectively clamp the dampers when they are put back in their original positions. Therefore, an adjustable fixing mechanism for transmission line conductor vibration dampers is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable fixing mechanism for vibration dampers on power transmission line conductors, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adjustable fixing mechanism for vibration dampers on power transmission line conductors, comprising: The fixing component includes a first claw clamp, a connecting tube, and a steel strand. The connecting tube is fixed to the middle of the steel strand, and the counterweight is fixed to both ends of the steel strand. The first claw clamp is fixed to the side of the connecting tube. The adjustment assembly includes a U-shaped connector, a through hole, a second connecting plate, an opening, and fastening bolts. The U-shaped connector is fixed to the side of the connecting pipe, the through hole is opened at the middle of both ends of the U-shaped connector, the second connecting plate is fixed to the lower end of the first claw clamp, the opening is opened in the middle of the second connecting plate, and the fastening bolts are inserted into the through hole and the opening and are fastened by nuts.
[0005] Furthermore, the adjustment assembly also includes a first connecting plate, one end of which is fixed to the side of the connecting pipe, and the other end of which is fixed to the side of the U-shaped connector.
[0006] Furthermore, the first claw clamps onto the external wire and is close to the wire's fixed end.
[0007] Furthermore, the first claw clamp includes an arc-shaped fixed block and an arc-shaped movable block, and the arc-shaped movable block is fastened to the arc-shaped fixed block by bolts.
[0008] Furthermore, it also includes a reinforcement component, which includes a second claw clamp and a reinforcing plate. The second claw clamp is fixed to the other end of the second connecting plate away from the first claw clamp, and the reinforcing plate is welded to the sides of the first claw clamp and the second claw clamp respectively.
[0009] Furthermore, the reinforcement assembly also includes a pre-hinged steel wire, which is wound around the external conductor and located on the sides of the first and second jaw clamps, respectively.
[0010] Furthermore, the second claw clamp is the same as the first claw clamp and clamps onto the external wire.
[0011] This utility model has the following beneficial effects: In this invention, by means of an adjustable component, the operator can loosen the fastening bolts, push the U-shaped connector along the second connecting plate, move the fastening bolts along the opening, and simultaneously move the connecting pipe below the first connecting plate, thereby moving the weights at both ends of the steel strand to the position with the best vibration damping effect. This design, through a stepless fine-tuning function, allows the vibration damping hammers to be restored to the optimal vibration damping position without having to reset the claw clamp position.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0017] Please see Figure 1-3 As shown, this utility model is an adjustable fixing mechanism for vibration dampers on power transmission line conductors, comprising: The fixing component includes a first claw clamp 10, a connecting tube 11 and a steel strand 12. The connecting tube 11 is fixed at the middle end of the steel strand 12, and the counterweight is fixed at both ends of the steel strand 12. The first claw clamp 10 is fixed on the side of the connecting tube 11. The first claw clamp 10 clamps onto the external conductor and is close to the conductor's fixed end; The first jaw clamp 10 includes an arc-shaped fixed block and an arc-shaped movable block, and the arc-shaped movable block is fastened to the arc-shaped fixed block by bolts; The first claw clamp 10 directly clamps the external conductor, providing a basic fixing function. The connecting tube 11 serves as the central hub of the fixing component, connecting other components. The steel strand 12 serves as a flexible connection carrier, with weights at both ends to form a dynamic damping system. It absorbs the vibration energy of the conductor through its own elastic deformation, suppressing fatigue damage.
[0018] The adjustment assembly includes a U-shaped connector 21, a through hole 22, a second connecting plate 23, an opening 24, and a fastening bolt 25. The U-shaped connector 21 is fixed to the side of the connecting pipe 11. The through hole 22 is opened in the middle of both ends of the U-shaped connector 21. The second connecting plate 23 is fixed to the lower end of the first claw clamp 10. The opening 24 is opened in the middle of the second connecting plate 23. The fastening bolt 25 is inserted into the through hole 22 and the opening 24 and is fastened by a nut. The adjustment assembly also includes a first connecting plate 20, one end of which is fixed to the side of the connecting pipe 11 and the other end of which is fixed to the side of the U-shaped connector 21; The first connecting plate 20 strengthens the structural stability of the connecting pipe 11 and the U-shaped connector 21. The U-shaped connector 21 provides a sliding track for adjustment operations to achieve lateral displacement adjustment. The through hole 22 and the opening 24 form the guide channel of the adjustment system, allowing the fastening bolt 25 to slide axially. The second connecting plate 23 connects the first claw clamp 10 to the adjustment system, transmitting the adjustment action to the clamping end. The fastening bolt 25 performs precise adjustment and locks the position, and stepless fine adjustment is achieved through the nut pair.
[0019] Working principle: The worker loosens the fastening bolt 25, pushes the U-shaped connector 21 along the second connecting plate 23, moves the fastening bolt 25 along the opening 24, and simultaneously moves the connecting pipe 11 below the first connecting plate 20, which in turn moves the counterweights at both ends of the steel strand 12 to the position where the vibration damping effect is optimal. This step, through the stepless fine-tuning function, allows the anti-vibration hammer to be restored to the optimal anti-vibration position without resetting the claw position.
[0020] Please see Figure 1-3 As shown, this embodiment, based on the above embodiment, further includes: The reinforcement assembly includes a second claw clamp 30 and a reinforcing plate 31. The second claw clamp 30 is fixed to the other end of the second connecting plate 23 away from the first claw clamp 10. The reinforcing plate 31 is welded to the sides of the first claw clamp 10 and the second claw clamp 30 respectively. The reinforcement assembly also includes a pre-hinged steel wire 32, which is wound around the external conductor and located on the sides of the first claw clamp 10 and the second claw clamp 30, respectively. The second jaw clamp 30 is the same as the first jaw clamp 10, and clamps onto the external wire; The second claw 30 provides secondary clamping protection, forming a double insurance with the first claw 10. The reinforcing plate 31 enhances the bending and torsional strength of the claw structure and prevents deformation under long-term stress. The pre-hinged steel wire 32 is wrapped around the surface of the external conductor and anchored to the sides of the first claw 10 and the second claw 30 respectively, forming multi-point constraints.
[0021] Working principle: After clamping the first claw 10 and the second claw 30 at the designated position of the wire, the pre-stitched steel wire 32 is wound around the wire so that one end of the two pre-stitched steel wires 32 abuts against the side of the first claw 10 and the second claw 30 respectively.
[0022] In this step, the second jaw clamp 30 and the first jaw clamp 10 form a "double clamping". The pre-stitched steel wire 32 is wrapped around the surface of the conductor and anchored to the sides of the two jaw clamps to form a multi-point constraint system. Through structural reinforcement and pre-tightening constraint, fatigue damage caused by repeated vibration is reduced, and maintenance frequency and cost are reduced.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
