[0002] With the rapid development of the power industry and the continuous expansion of the power grid, the requirements for the safety and stability of transmission lines are increasing.

[0003] In power transmission lines, vibration damping hammers are an important vibration damping device that is widely used to reduce the vibration of conductors caused by wind vibration and other factors, so as to protect the lines and accessories from damage. However, the vibration damping hammer devices in the prior art have many inconveniences in the installation and removal process, such as cumbersome installation steps, the need for special tools and long operation time, and difficulty in removal. In addition, during long-term use, due to the friction and wear between the conductor and the wire clamp, the vibration damping hammer is easily loosened or even falls off, affecting the vibration damping effect and increasing the difficulty and cost of line maintenance.

[0004] It can be seen that how to optimize the structure of the anti-vibration hammer has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The invention provides an anti-vibration hammer to achieve the effect of easy installation of the anti-vibration hammer.

[0006] In order to solve the above technical problems, an embodiment of the present invention provides an anti-vibration hammer, including a wire clamp, a fastener, a steel strand, a first anti-vibration weight and a second anti-vibration weight.

[0007] The wire clamping end of the wire clamp comprises a first clamping section and a second clamping section, and working surfaces of the first clamping section and the second clamping section enclose and form a clamping channel matching the wire to be clamped.

[0008] The wire clamp is provided with first holes respectively penetrating the first clamping section and the second clamping section. The first clamping section and the second clamping section are pre-fixed on the wire to be clamped by passing through the first holes with the aid of external auxiliary tools.

[0009] The wire clamp is provided with second holes respectively penetrating the first clamping section and the second clamping section, and the first clamping section and the second clamping section are fixed to each other by the fastener passing through the second holes.

[0010] The steel strand passes through the connection end of the wire clamp, and one end of the steel strand is connected to the first anti-vibration weight, and the other end of the steel strand is connected to the second anti-vibration weight.

[0011] Furthermore, the second hole position is arranged at the centroid position of the second clamping section, and the distance between the first hole position and the second hole position is equal to the distance between the second hole position and the wire to be clamped.

[0012] Furthermore, the fastener is a stud, the stud is provided with an external thread, and the inner side of the second hole is provided with an internal thread matching the external thread.

[0013] Furthermore, working surfaces of the first clamping section and the second clamping section are both provided with rubber pads, and the rubber pads are completely in contact with the wire to be clamped when the wire clamping end clamps the wire to be clamped.

[0014] Furthermore, the first clamping section is also provided with a latch hole and a safety latch.

[0015] The safety pin passes through the pin hole and penetrates both sides of the first clamping section.

[0016] Furthermore, the safety latch is made of high-strength aluminum alloy material.

[0017] Furthermore, the first anti-vibration weight and the second anti-vibration weight have the same weight and shape.

[0019] Furthermore, anti-slip threads are provided inside the first hole and the pin hole.

[0020] Furthermore, the surface of the wire clamping end is provided with a waxy anti-corrosion coating.

[0021] Compared with the prior art, the embodiments of the present invention have the following advantages: The design of auxiliary holes and fasteners makes the installation and removal of the anti-vibration hammer simpler and faster. The hollow hole design of the auxiliary holes allows the use of wire spacer wrench auxiliary tools for initial clamping, reducing the damping force required during the tightening process, thereby improving the installation efficiency. The design of the hexagonal bolt makes tightening and loosening operations more convenient and reduces the difficulty of maintenance and replacement.

[0022] The pin made of high-strength alloy can prevent the anti-vibration hammer from dislocating when the bolt in the fastener fails. This design effectively avoids line failures and safety accidents that may be caused by the anti-vibration hammer falling off, and improves the safety and stability of the anti-vibration hammer under extreme conditions.

[0028] An embodiment of the present invention provides an anti-vibration hammer. For details, see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of an anti-vibration hammer provided in one embodiment of the present invention is shown. Figure 2 It is a side view of the same anti-vibration hammer, including a wire clamp, a fastener, a steel strand 11 , a first anti-vibration weight 131 and a second anti-vibration weight 132 .

[0029] Among them, Figure 1 As shown, the wire clamp includes a wire clamping end 12 and a connecting end 121. The upper part of the wire clamp is the wire clamping end 12, which is used to clamp the wire 20 to be clamped during work. The lower part of the wire clamp is the connecting end 121, which is used to connect the wire clamp and the anti-vibration weight. The anti-vibration weight includes a first anti-vibration weight 131 and a second anti-vibration weight 132.

[0030] Specifically, the clamping end 12 of the clamp includes a first clamping section 123 and a second clamping section 122, wherein Figure 2 As shown, the first clamping section 123 and the lower connecting end 121 are an integral structure, while the second clamping section 122 can be separated from the anti-vibration hammer body.

[0031] The working surfaces of the first clamping section 123 and the second clamping section 122 can enclose and form a clamping channel that matches the wire 20 to be clamped.

[0032] The working surfaces of the first clamping section 123 and the second clamping section 122 are both provided with rubber pads, and the rubber pads are completely in contact with the wire to be clamped when the wire clamping end clamps the wire to be clamped.

[0033] Specifically, the second clamping section 122 is also hinged to the first clamping section 123 through the lowest position, and the outer side surface of the bottom of the second clamping section is an inclined surface that gradually approaches the inner side surface from top to bottom. When the first clamping section 123 and the second clamping section 122 are not fastened by fasteners, that is, in the non-working mode, the second clamping section 122 and the entire anti-vibration hammer body are movably hinged through the bottom of the second clamping section 122.

[0034] like Figure 1As shown, the wire clamp is also provided with a second hole 14, which is a fastening hole corresponding to the first clamping section 123 and the second clamping section 122. When the anti-vibration hammer is in normal working state, the first clamping section 123 and the second clamping section 122 are fixed by fasteners passing through the second hole 14.

[0035] Specifically, the fastener of this embodiment is a stud, specifically a hexagonal bolt, with an external thread on the stud, and an internal thread matching the external thread on the inner side of the second hole 14. The hexagonal bolt can be tightened or loosened by using a hexagonal wrench tool, has high strength and stability, and can provide sufficient tightening force to ensure that the clamping module is firmly fixed on the conductor. The standardized design of the hexagonal bolt also facilitates the replacement and maintenance of spare parts, reduces maintenance costs, and further enhances the reliability and durability of the anti-vibration hammer. The wire clamp is also provided with a first hole 15 that passes through the first clamping section 123 and the second clamping section 122. The first hole 15 serves as an auxiliary hole, correspondingly passing through the first clamping section 123 and the second clamping section 122. The first hole 15 can be penetrated by an external auxiliary tool to achieve pre-fixation of the anti-vibration hammer on the wire 20 to be clamped.

[0036] The steel strand 11 passes through the connection end 121 of the wire clamp, and one end of the steel strand 11 is connected to the first anti-vibration weight 131 , and the other end of the steel strand 11 is connected to the second anti-vibration weight 132 .

[0037] The first hole position 15 of the present embodiment is used as an auxiliary hole position to assist the installation process when the anti-vibration hammer is installed on the wire to be clamped 20. Specifically, before using the fastener to fasten the wire clamp to the wire to be clamped 20 through the second hole position 14, the anti-vibration hammer is pre-fixed on the wire to be clamped 20 through the first hole position 15. The auxiliary hole position can be passed through by a wire spacer wrench such as a wire spacer wrench and simply fixed on the wire to be clamped 20, so that the first clamping section 123 and the second clamping section 124 are connected. The segments 122 form a contacting and merged state, so that the conductor 20 to be clamped is clamped between the first clamping segment 123 and the second clamping segment 122, and then the installation tool is used to tighten and fix the hexagonal bolt on the first clamping segment 123 and the second clamping segment 122. Pre-fixing the anti-vibration hammer in advance through the auxiliary hole position can reduce the damping force caused by the wire clamp clamping the conductor 20 to be clamped during the tightening of the hexagonal bolt, increase the tightening effect of the fastener and the second hole position 14, and facilitate the installation process of the anti-vibration hammer.

[0038] The setting of the auxiliary hole position provides a stable support point for the installation and disassembly operation, so that the anti-vibration hammer can be aligned and fixed more accurately during the installation process. In addition, this auxiliary method effectively disperses the stress that may be generated during the fastening process, protects the wire and the anti-vibration hammer itself, and prolongs the service life. By first clamping with the auxiliary hole position and then fastening, it ensures that the anti-vibration hammer can be firmly and stably installed on the wire, and maintains a good anti-vibration effect even in harsh climatic conditions.

[0039] Preferably, in order to enhance the clamping effect of the wire clamp on the wire 20 to be clamped, the fastening hole, ie, the second hole 14 is arranged at the centroid position of the front view of the second clamping section 122 of the wire clamp in this embodiment.

[0040] In order to further reduce the damping force caused by the wire clamp clamping the wire 20 to be clamped during the tightening of the hexagonal bolt, the damping force that needs to be overcome during the installation process is tested for the setting positions of multiple first holes 15. It is finally concluded that the damping force that needs to be overcome is the smallest when the distance between the center of the first hole 15 and the center of the second hole 14 is equal to the axial distance between the second hole 14 and the wire 20 to be clamped, as shown in Table 1: Wherein, L1 is the axial distance between the second hole 14 and the conductor 20 to be clamped, L2 is the distance between the center of the first hole 15 and the center of the second hole 14, and Fc is the damping force measured during the tightening of the bolt.

[0041] Preferably, the anti-vibration hammer of this embodiment also includes a safety module, which is arranged on the first clamping section 123, including a latch hole 16 and a safety latch passing through the latch hole and extending through both sides of the first clamping section, and the safety latch is made of high-strength aluminum alloy material. The design of the safety module provides additional safety protection for the anti-vibration hammer, and can effectively prevent the anti-vibration hammer from dislocating even in extreme cases when the bolt fails. The insertion and removal process of the latch is simple and quick, and only needs to be inserted after the hexagonal bolt of the fastening module is tightened. Once the bolt in the fastening module fails for some reason, the latch will play its insurance role to prevent it from falling off the wire. This design not only improves the safety of the anti-vibration hammer, but also effectively avoids line failures and safety accidents that may be caused by the falling off of the anti-vibration hammer. At the same time, the replaceable design of the latch also greatly facilitates subsequent maintenance and overhaul work, reducing operation and maintenance costs.

[0042] In addition, the overall structure of the anti-vibration hammer in this embodiment is designed with weight distribution in mind. The first anti-vibration weight 131 and the second anti-vibration weight 132 have the same weight and shape to ensure the balance and stability of the anti-vibration hammer on the conductor 20 to be clamped, thereby reducing the impact of vibration on the conductor 20 to be clamped.

[0043] The length of the steel strand 11 is greater than the length of the clamping end 12. In the length direction of the steel strand 11, the length of the clamping end 12 is equal to the length of the connecting end 121. The length setting is relatively scientific and reasonable, which not only ensures that the anti-vibration hammer has a better clamping effect on the conductor, but also saves production materials and reduces the production cost of the anti-vibration hammer. At the same time, it effectively suppresses the vibration of the conductor caused by wind, greatly reducing the operation and maintenance costs of the power grid and the risks of manual maintenance operations.

[0044] Preferably, the first hole 15 and the pin hole 16 of this embodiment are provided with anti-slip threads inside, and the anti-slip threads of the first hole 15 are used to reduce the relative position phenomenon between the first clamping section 123 and the second clamping section 122 caused by the tightening behavior during auxiliary installation work.

[0045] Preferably, the surface of the wire clamping end 12 of this embodiment is provided with a wax anti-corrosion coating to prevent the anti-vibration hammer from being corroded at the contact portion with the wire 20 to be clamped due to long-term exposure to the natural environment during operation.

[0046] The anti-vibration hammer of the present invention makes the installation and disassembly process of the anti-vibration hammer simpler and faster by designing auxiliary holes and fasteners. The hollow hole design of the auxiliary holes allows the use of wire spacer wrench auxiliary tools for preliminary clamping, reducing the damping force required during the tightening process, thereby improving the installation efficiency. The design of the hexagonal bolt makes the tightening and loosening operations more convenient, reducing the difficulty of maintenance and replacement. The pin made of high-strength alloy can prevent the anti-vibration hammer from dislocating when the bolt in the fastener fails. This design effectively avoids line failures and safety accidents that may be caused by the falling off of the anti-vibration hammer, and improves the safety and stability of the anti-vibration hammer under extreme conditions. The anti-skid rubber pad and anti-skid texture on the inner side of the clamping end further enhance the clamping effect, ensuring that the anti-vibration hammer remains firm during vibration.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
