Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of vibration damping hammer technology, specifically to a hinged vibration damping hammer for ultra-high voltage applications. Background Technology
[0002] Hinged vibration dampers typically consist of two hammerheads connected by steel strands. To improve their vibration reduction effect, damping rubber pads or other components can be installed between the clamps and connectors of the hinged vibration damper. This effectively eliminates or reduces the swaying and vibration of power lines caused by external environmental factors such as wind, ice, and low temperatures, ensuring the safe and stable operation of the lines.
[0003] An existing patent (publication number: CN221978588U) discloses an anti-slip sleeve for a vibration damper of a power transmission line, including an upper body of the anti-slip sleeve. The upper end face of the upper body of the anti-slip sleeve has multiple first threaded holes symmetrically formed, each threaded hole containing a first bolt. A lower body of the anti-slip sleeve is provided on the lower end face of the upper body of the anti-slip sleeve. An installation groove is formed inside the upper body of the anti-slip sleeve, and a rubber airbag is fixedly connected to the installation groove. A through hole is formed on the upper end face of the rubber airbag, and a connecting pipe is fixedly connected to the through hole. Two air cylinders are fixedly connected to the upper end face of the upper body of the anti-slip sleeve. This invention uses air cylinders to inflate the rubber airbag, increasing the air volume and allowing it to press against the power transmission line clamped within the anti-slip sleeve, thereby increasing friction on the power transmission line and better limiting its movement. This prevents the vibration damper from slipping, ensuring that the weight of the vibration damper itself can effectively dampen the power transmission line.
[0004] In the process of realizing this solution, the inventor found that the anti-slip sleeve's structural design requires the anti-slip sleeve to be connected and cooperate with the bolts during installation. The installation of the anti-vibration hammer requires workers to be suspended outside the cable for high-altitude operations. The current anti-slip sleeve structural design requires users to free their hands to hold the anti-slip sleeve outside the power line before tightening the bolts, which presents a technical problem of inconvenient assembly operations.

[0040] See attached document Figure 1-6 This utility model provides a hinged vibration damper for ultra-high voltage applications, comprising the following structure:
[0041] The main wire clamp 1 has an auxiliary wire clamp 2 hinged to its front end. The outer side of the main wire clamp 1 is detachably snapped to the rear end of the leaf spring 4, and the front end of the leaf spring 4 is detachably snapped to the front end of the auxiliary wire clamp 2.
[0042] The spiral connector 8 has a third retainer 9 symmetrically engaged at the top front and back, and a clamping piece 91 is fixed in the middle of the third retainer 9.
[0043] In this embodiment, the rear end of the main clamp 1 is fixedly provided with a first retainer 11 that matches the rear end of the leaf spring 4, the front side of the main clamp 1 is nested with a first damping rubber pad 12, the rear side of the main clamp 1 is fixedly provided with a reinforcing rib, and the outer side of the main clamp 1 is detachably snapped into one end of the spiral connector 8.
[0044] The design of the first bracket 11 of the main clamp 1 and the second bracket 21 of the auxiliary clamp 2 completes the assembly of the leaf spring 4 on the outside of the main clamp 1 and the auxiliary clamp 2. Without external force interference, the leaf spring 4 completes the pre-locking of the auxiliary clamp 2 and the main clamp 1. Combined with the design of the cable inlet 3, it is convenient for users to attach the cable inlet 3 of the main clamp 1 and the auxiliary clamp 2 to the outside of the cable, making it convenient for the cable to be installed between the main clamp 1 and the auxiliary clamp 2. Then, the assembly position of the main clamp 1 and the auxiliary clamp 2 is locked by bolts. This installation operation is simple and convenient, making it convenient for users to suspend the cable outside for construction.
[0045] In this embodiment, the front side of the auxiliary clamp 2 is fixedly provided with a second card seat 21 that matches the front end of the leaf spring 4, the rear side of the auxiliary clamp 2 is nested with a second damping rubber pad 22, the bottom rear side of the auxiliary clamp 2 and the bottom front side of the main clamp 1 are fixedly provided with a wire inlet 3, the opening of the wire inlet 3 facing the bottom of the auxiliary clamp 2 is larger than its opening facing the top of the auxiliary clamp 2, and the bottom of the auxiliary clamp 2 and the middle part of the main clamp 1 are fixedly connected by bolts.
[0046] The installation of the first damping rubber pad 12 and the second damping rubber pad 22 improves the vibration reduction effect of this device on the outside of the cable.
[0047] In this embodiment, the rear end and the front end of the leaf spring 4 are respectively fixed with a first positioning protrusion 41 and a second positioning protrusion 42. The first positioning protrusion 41 cooperates with the first card seat 11, and the second positioning protrusion 42 cooperates with the second card seat 21.
[0048] When the cable is inserted between the main clamp 1 and the auxiliary clamp 2, the auxiliary clamp 2 deflects at the hinge point with the main clamp 1. At this time, the leaf spring 4 is opened. After the cable is fully inserted between the main clamp 1 and the auxiliary clamp 2, the leaf spring 4 returns to its original position to complete the closing process of the main clamp 1 and the auxiliary clamp 2, thus preventing the bolts of the main clamp 1 and the auxiliary clamp 2 from loosening before assembly, which could cause the device to fall off the outside of the cable.
[0049] In this embodiment, a connecting seat 5 is fixedly provided at the bottom of the main clamp 1, and a connecting hole 51 is fixedly provided at the bottom end of the connecting seat 5. The connecting hole 51 at the bottom end of the connecting seat 5 is hinged to the outside of the steel strand 6. Hammers 7 are riveted to both ends of the steel strand 6, and the connection between the hammers 7 and the steel strand 6 is tinned.
[0050] Below the main clamp 1, a connecting seat 5, a steel strand 6, and a hammer head 7 are installed to complete the basic structure assembly of the hinged vibration damper.
[0051] In this embodiment, the spiral connector 8 is composed of a spiral spring covered with damping rubber, and the spiral connector 8 is symmetrically arranged about the main clamp 1.
[0052] The spiral connector 8 completes the assembly of the main clamp 1 and the third card holder 9 on the outside of the cable. The design of the clamping piece 91 on the third card holder 9 facilitates the stable assembly of the third card holder 9 on the outside of the cable via the connecting bolt 92. The spiral connector 8 and the third card holder 9 are set on the outside of the main clamp 1 to prevent the main clamp 1 and the auxiliary clamp 2 from becoming loose on the outside of the cable, which could cause the hinged anti-vibration hammer to shift or fall off.
[0053] In this embodiment, the tops of the two third card holders 9 are respectively sleeved with the front and rear sides of the connecting bolt 92.
[0054] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
