Description

Technical Field

[0001] This utility model relates to the field of vibration damping hammer technology, specifically to vibration damping hammer devices. Background Technology

[0002] Overhead power lines frequently vibrate or gallop due to wind influence, causing repeated bending at suspension points, leading to material fatigue and ultimately strand or wire breakage. To reduce vibration and galloping, vibration dampers are installed at suspension points, often near fixed equipment such as insulator strings (near the ends of the line), to absorb or reduce the energy of vibration or galloping and alter the swaying frequency of the overhead line.

[0003] According to CN212304673U, a vibration damping device is disclosed. This technology discloses "a vibration damping device, including: a vibration damping mechanism, which includes at least a hammer body for suspension on an overhead line; a pull line for connecting a fixed device and the vibration damping mechanism to restrict the movement of the hammer body away from the fixed device". It has the technical effect of "using the pull line to restrict the vibration damping mechanism, which can effectively prevent the hammer body from slipping and deviating, without the need to retrieve the hammer body".

[0004] While the above solution can prevent the vibration damper from slipping significantly by using a cable, the vibration damper is fixed to the overhead line by a clamp and bolts. Since the original design of the vibration damper is to consume the vibration energy of the overhead line through its unique vibration frequency, thereby protecting the line from vibration damage, the bolts are prone to loosening under long-term vibration, causing the vibration damper to deviate from its initial installation position. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vibration damper device. When vibration of the overhead line causes the nut to loosen, the bolt will not detach from the sleeve, thus not affecting the sleeve's fixation of the fixing component. This allows the vibration damper mechanism to always maintain a tight clamping fixation on the overhead line, preventing the vibration of the overhead line from causing the vibration damper mechanism to shift position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration damper device, comprising an overhead line, wherein a vibration damper mechanism is provided on the overhead line and is used to dissipate the vibration energy of the overhead line through vibration frequency, the vibration damper mechanism comprising:

[0007] The mounting assembly includes two housings mounted on the overhead line; the two housings are connected to each other to form a mounting cavity; two mating fasteners are installed inside the mounting cavity along the length of the overhead line; the fasteners are also fitted with beveled rings, and the beveled rings are located inside the mounting cavity.

[0008] The shell frame is fitted with fasteners at both ends, and the fasteners at both ends are connected by a sleeve. A bolt is installed through the inside of the sleeve, and a nut is threaded onto one end of the bolt.

[0009] The hammer assembly includes a steel strand mounted below one of the housings, with hammers fixed at both ends of the steel strand.

[0010] Preferably, the fastener includes two mating heads installed inside the housing, with a through hole formed between the two mating heads; each of the two heads is provided with a slot, and the opening of the slot faces away from the mounting cavity.

[0011] Preferably, the fastener further includes a protrusion fixed to the inner wall of the fastener head, the protrusion being used to fix the overhead line extending into the through hole; the fastener head is made of rubber.

[0012] Preferably, the fixing member includes two shell sleeves that are sleeved and installed at the end of the shell frame. The shell sleeves have semi-circular openings. The semi-circular openings of the two shell sleeves in the same fixing member are correspondingly arranged to form a connecting hole that communicates with the through hole. The through hole and the connecting hole are used to install the overhead line.

[0013] Preferably, the fixing member further includes fixing ears fixed to the outer walls on both sides of the shell, the fixing ears being used to connect with the frame; the two fixing ears on the same shell are staggered relative to the shell.

[0014] Preferably, the mounting assembly further includes a bracket fixed to the bottom of the housing, the lower end of which is fixed with two arc-shaped heads for connecting to the hammer assembly.

[0015] Preferably, the hammer assembly further includes a mounting sleeve fixed in the middle of the outer wall of the steel strand, with retaining rings fixed at both ends of the mounting sleeve; the two arc-shaped heads are connected to the outer surface of the mounting sleeve.

[0016] Beneficial effects

[0017] This utility model provides a vibration damper device. Compared with the prior art, it has the following advantages:

[0018] 1. When the vibration damper mechanism needs to be installed on an overhead line, the inclined ring is placed on the fastener and then placed into the housing. The two housings are then symmetrically assembled. The upper and lower fixing parts are then symmetrically assembled and placed on the ends of the housings. The sleeve is then placed between the fixing parts at both ends, and bolts are passed through the housing and the sleeve to fix the fixing parts. At the same time, after the fixing parts are fixed, the inclined ring can be pushed inward, and the inclined ring squeezes the fastener to tighten, thereby clamping the overhead line and fixing the vibration damper mechanism to the overhead line. When the overhead line vibrates and the nut loosens, the bolt will not come off the sleeve, so it will not affect the fixing of the fixing parts by the sleeve. This allows the vibration damper mechanism to always maintain a tight clamp on the overhead line, preventing the vibration of the overhead line from causing the vibration damper mechanism to shift position.

[0019] 2. The modular design of the mounting components in the vibration damper mechanism allows for individual replacement of a faulty or damaged module during maintenance, eliminating the need to replace the entire module and reducing maintenance costs. Furthermore, the mounting components and the hammer head assembly are detachable, allowing for the replacement of compatible mounting components and hammer head assemblies to adapt to changes in line operating conditions, such as wind speed and conductor material.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a vibration damper device, including an overhead line 1, on which a vibration damper mechanism 2 is installed and used to dissipate the vibration energy of the overhead line 1 through vibration frequency. The vibration damper mechanism 2 includes:

[0029] The mounting assembly 21 includes two housings 211 mounted on the overhead line 1; the two housings 211 are connected to each other to form a mounting cavity; two fasteners 213 are installed inside the mounting cavity along the length of the overhead line 1; the fasteners 213 are also fitted with inclined ring sleeves 214, and the inclined ring sleeves 214 are located inside the mounting cavity.

[0030] Among them, the two ends of the shell frame 211 are fitted with fasteners 215, and the two ends of the fasteners 215 are connected by a sleeve 216. A bolt 217 is installed through the sleeve 216, and a nut 218 is threaded on one end of the bolt 217.

[0031] The hammer assembly 22 includes a steel strand 221 installed under one of the housings 211, with hammers 222 fixed at both ends of the steel strand 221.

[0032] In this embodiment, when the anti-vibration hammer mechanism 2 needs to be installed on the overhead line 1, the inclined ring 214 is fitted onto the fastener 213 and placed into the housing 211. The two housings 211 are then symmetrically assembled. The upper and lower fixing members 215 are then symmetrically assembled and fitted onto the ends of the housings 211. A sleeve 216 is then fitted between the fixing members 215 at both ends, and bolts 217 are passed through the housing 2151 and the sleeve 216 to fix the fixing members 215. Simultaneously, after the fixing members 215 are fixed, they can... Pushing the inclined ring 214 inward causes the inclined ring 214 to compress the fastener 213, thereby clamping the overhead line 1 and fixing the anti-vibration hammer mechanism 2 to the overhead line 1. When the overhead line 1 vibrates, causing the nut 218 to loosen, the bolt 217 will not come off the sleeve 216, so it will not affect the fixation of the sleeve 216 to the fastener 215. This allows the anti-vibration hammer mechanism 2 to always maintain clamping and fixing the overhead line 1, preventing the anti-vibration hammer mechanism 2 from shifting position due to vibration of the overhead line 1.

[0033] Specifically, the fastener 213 includes two mating fasteners 2131 installed inside the housing 211, with a through hole formed between the two mating fasteners 2131; each of the two fasteners 2131 has a slot 2132, and the opening of the slot 2132 faces away from the mounting cavity.

[0034] In this embodiment, the structure of the tightening head 2131 is as follows: Figure 5 As shown, the two interlocking clamps 2131 can form a circular through hole by fastening, allowing the subsequent overhead line 1 to pass through. When the clamps 2131 are squeezed, they can also have a certain shrinkage space through the slot 2132.

[0035] Specifically, the fastener 213 also includes a protrusion 2133 fixed to the inner wall of the fastener 2131, the protrusion 2133 being used to fix the overhead line 1 extending into the through hole; the fastener 2131 is made of rubber.

[0036] In this embodiment, when the clamping head 2131 is squeezed, the overhead line 1 can be further compressed through the protrusion 2133.

[0037] Specifically, the fastener 215 includes two housing sleeves 2151 sleeved and installed at the same end of the housing frame 211. The housing sleeves 2151 are provided with semi-circular openings 2153. The semi-circular openings 2153 of the two housing sleeves 2151 in the same fastener 215 are correspondingly arranged to form a connecting hole that communicates with the through hole. The through hole and the connecting hole are used to install the overhead line 1.

[0038] Therefore, it can be seen that the overhead line 1 is actually inserted into the through hole formed by the fastener 215 at one end, and then sequentially enters the through hole formed by the two fasteners 213 at each of the two fastener heads 2131. Then it is passed out through the fastener 215 at the other end, and finally the fixation with the overhead line 1 is completed.

[0039] In addition, the fastener 215 also includes fixing ears 2152 fixed to the outer walls of both sides of the housing 2151. The fixing ears 2152 are used to connect with the sleeve 216. The two fixing ears 2152 on the same housing 2151 are staggered relative to the housing 2151.

[0040] In this embodiment, after the upper and lower housings 2151 are fixed on the housing frame 211, the fixing ears 2152 on the upper and lower housings 2151 can be staggered and aligned. After the housing frame 216 is put on the fixing ears 2152, the housings 2151 can be fixed. Furthermore, when the bolts 217 are installed later, they can pass through the housings 2151 and the fixing ears 2152 on the upper and lower housings 2151.

[0041] Specifically, the mounting assembly 21 also includes a bracket 212 fixed to the bottom of the housing 211. Two arc-shaped heads 219 are fixed to the lower end of the bracket 212, and the two arc-shaped heads 219 are used to connect to the hammer assembly 22.

[0042] In this embodiment, after the two housing frames 211 are fixed, the hammer assembly 22 can be fixed by the bracket 212 in conjunction with the arc-shaped head 219.

[0043] Specifically, the hammer assembly 22 also includes a mounting sleeve 223 fixed in the middle of the outer wall of the steel strand 221, with retaining rings 224 fixed at both ends of the mounting sleeve 223; and two arc-shaped heads 219 connected to the outer surface of the mounting sleeve 223.

[0044] In this embodiment, the mounting sleeve 223 is fixed by the arc-shaped heads 219 on the two brackets 212, and the axial movement of the arc-shaped heads 219 is prevented by the retaining ring 224.

[0045] The working principle and usage process of this utility model are as follows: First, when the anti-vibration hammer mechanism 2 needs to be installed on the overhead line 1, the inclined ring 214 is placed on the fastener 213 and then placed into the shell 211. The two shells 211 are then symmetrically assembled. The upper and lower fixing parts 215 are then symmetrically assembled and placed on the ends of the shells 211. The sleeve 216 is then placed between the fixing parts 215 at both ends, and the bolts 217 are passed through the shell 2151 and the sleeve 216 to fix the fixing parts 215. At the same time, after the fixing parts 215 are fixed, the inclined ring 214 can be pushed inward, and the inclined ring 214 squeezes the fastener 213 to tighten, thereby clamping the overhead line 1 and fixing the anti-vibration hammer mechanism 2 on the overhead line 1.

[0046] Meanwhile, once the two housings 211 are fixed, the mounting sleeve 223 can be fixed by the bracket 212 in conjunction with the arc-shaped head 219, thereby achieving the simultaneous fixing of the hammer assembly 22.
