Description

Technical Field

[0001] This application relates to the technical field of power equipment, and in particular to a vibration damper and its installation device. Background Technology

[0002] Overhead power lines are frequently subjected to vibrations due to wind, causing repeated bending and bending near the insulator strings, leading to material fatigue and ultimately, high-voltage line breakage. To reduce overhead power line vibration, vibration dampers are installed at the suspension points to absorb vibration energy and reduce the vibration of the overhead power line.

[0003] In related technologies, the vibration damper includes two opposing clamps, a connecting rod, an elastic support rod, and two plumb bobs. One end of the connecting rod is fixedly connected to the two clamps, and the other end is fixedly connected to the middle of the elastic support rod. The two plumb bobs are connected to both ends of the elastic support rod. When the vibration damper is connected to an overhead line, the two clamps hold the overhead line, and then screws are inserted through the two clamps to lock the two clamps, thereby connecting the vibration damper to the overhead line.

[0004] Regarding the aforementioned technologies, the vibration damper is connected to the overhead line via a clip. Although the vibration damper is not easy to fall off the overhead line, it is easy for it to slide on the overhead line when the wind is strong, causing the position of the vibration damper to change. Summary of the Invention

[0005] Firstly, in order to prevent the vibration damper from slipping on the cable, this application provides a vibration damper.

[0006] This application provides a vibration damper, which adopts the following technical solution:

[0007] A shock absorber includes two clamping plates for holding cables, a connecting rod, an elastic rod, and two hammer bodies respectively connected to both ends of the elastic rod. The two clamping plates are arranged opposite each other to form a clamping cavity for the cable to be embedded. One end of the connecting rod is connected to the two clamping plates, and the other end is connected to the middle of the elastic rod.

[0008] The shock absorber also includes a pull rope. The clamp is bent away from the other clamp to form a rope hole. One end of the pull rope is connected to a fixing device on the cable, and the other end passes through the two rope holes in sequence and is connected to the clamp.

[0009] By adopting the above technical solution, when installing the vibration damper, the two clips of the vibration damper are clamped onto the cable, so that the cable is embedded in the clamping cavity, and the vibration damper is connected to the cable through the clips.

[0010] After the vibration damper is installed on the cable, it is easily slipped along the length of the cable due to the wind. After a long time, the vibration damper will usually slide to the middle of the cable. However, the installation position of the vibration damper on the cable is generally fixed. When the vibration damper is in the middle of the cable, the vibration damping effect is poor.

[0011] In order to prevent the vibration damper from sliding on the cable, a pull rope is installed on the vibration damper. One end of the pull rope is connected to a fixing device, which is a device installed on the cable. In this embodiment, it is an insulator string. Because the insulator string is fixed on the cable, the vibration damper is more stable on the cable after being connected to the insulator string by the pull rope, and the vibration damper is less likely to slide on the cable.

[0012] Secondly, this application provides a mounting device for a vibration damper, which adopts the following technical solution:

[0013] An installation device for a vibration damper includes a frame with upper rollers and a support frame with lower rollers. The upper rollers and lower rollers are arranged opposite each other and clamp cables. The support frame is provided with a support assembly for supporting the vibration damper. The support assembly includes a support plate for supporting the vibration damper and a clamping screw for moving the support plate on the support frame. The clamping screw is threaded through the support frame, and the end of the clamping screw abuts against the support plate.

[0014] By adopting the above technical solution, the upper and lower rollers clamp the cable, making the installation device stable on the cable and enabling the anti-vibration hammer to move on the cable. When using the installation device, the anti-vibration hammer is placed on the support plate, and the installation device moves on the cable. When the installation device moves to the position where the anti-vibration hammer is installed, the clamping screw is turned. The clamping screw pushes the support plate upward, and the support plate drives the anti-vibration hammer to move, so that the cable enters the clamping cavity between the two clamping plates, and the cable is clamped by the clamping plates.

[0015] Optionally, the support frame is provided with a roller clamping assembly, which includes a compression spring and a force transmission plate. The force transmission plate abuts against the rotating shaft of the lower roller, one end of the compression spring abuts against the support frame, and the other end abuts against the side of the force transmission plate away from the rotating shaft.

[0016] By adopting the above technical solution, a compression spring acts on a force transmission plate, which in turn acts on the shaft of the lower roller. This ensures that the lower roller always tends to move closer to the upper roller. When the installation device is in use, the upper roller abuts against the cable, and the compression spring causes the lower roller to also abut against the cable, making the installation device more stable and allowing for smoother movement on the cable. Since the compression spring acts on the shaft of the lower roller, directly contacting the spring would easily cause radial displacement and bending, making it difficult to fully transmit the spring's force to the lower roller. By placing a force transmission plate between the compression spring and the lower roller's shaft, the spring's force is fully transmitted to the lower roller, and the spring is less prone to radial displacement or bending.

[0017] Optionally, the support frame has a spring groove for mounting the compression spring, the compression spring is located in the spring groove, and the shafts of the force transmission plate and the lower roller can slide within the spring groove.

[0018] By adopting the above technical solution, the compression spring is installed in the spring groove, making it less prone to radial displacement or bending during extension and contraction, thus improving the service life of the compression spring. Furthermore, the pivots of the force transmission plate and the lower roller also slide within the spring groove, making the movement of the lower roller and the force transmission plate more stable.

[0019] Optionally, the force transmission plate protrudes outward from the spring groove to form a pressure plate, and the support plate includes a supporting part and an abutting part for supporting the shock absorber. The abutting part is located below the pressure plate, and the clamping screw abuts against the side of the abutting part away from the pressure plate.

[0020] By adopting the above technical solution, the abutment part is located below the pressure plate. When the clamping screw drives the support plate to move upward, the abutment part also moves upward and abuts against the pressure plate. The abutment part presses the pressure plate, and the pressure plate presses the shaft of the lower roller, making it difficult for the lower roller to rotate. This makes it difficult for the installation device to move on the cable, making the installation of the vibration damper easier and the installation position more accurate.

[0021] Optionally, the abutting portion has a fixing groove for the end of the clamping screw to be inserted into the fixing groove.

[0022] By adopting the above technical solution, the clamping screw is restricted by the fixing groove, making it difficult for the clamping screw to move on the abutment part, thereby making the clamping screw act more stably on the abutment part.

[0023] Optionally, the scaffold has a first side plate and a second side plate arranged in parallel, and the support frame has a rotating plate and a locking plate arranged in parallel. The rotating plate is rotatably connected to the first side plate through a rotating shaft. The locking plate is provided with a positioning block, and the second side plate has a positioning groove for the positioning block to be inserted. The positioning block is connected to the second side plate by a locking screw.

[0024] By adopting the above technical solution, the positioning plate and the second side plate are connected by locking screws to ensure a stable connection between the support frame and the support frame. When the installation device is used on the cable, the support frame is rotated in advance, and the support frame is rotated to one side of the support frame via the rotating shaft, so that the support frame and the support frame are misaligned. Then the support frame is placed on the cable, and both upper rollers abut against the cable. Then the support frame is rotated again, so that the support frame rotates to the bottom of the support frame, and the lower roller abuts against the cable. The action of the upper roller and the lower roller allows the installation device to move on the cable. At the same time, the positioning block is embedded in the positioning groove, and a locking screw is inserted through the positioning block. The locking screw is screwed into the second side plate to fix the support frame and the support frame relatively, making it difficult for the support frame to rotate.

[0025] Optionally, the support frame is provided with an unlocking plate, one end of which is rotatably connected to the shaft of the lower roller, and the other end is provided with a slot for the clamping screw to be inserted.

[0026] By adopting the above technical solution, after the vibration damper is installed, loosen the clamping screw so that it is turned away from the cable, so that the abutment part no longer presses against the pressure plate, and the pressure plate no longer presses against the lower roller's shaft. Then pull the unlocking plate, which pulls the lower roller's shaft away from the upper roller, so that the lower roller no longer abuts against the cable, and there is a distance between the lower roller and the cable, which facilitates the rotation of the support frame. Rotate the support frame to one side of the frame so that the installation device can be removed from the cable. After the unlocking plate pulls the lower roller's shaft away from the upper roller, fasten the end of the unlocking plate away from the lower roller onto the clamping screw. The clamping screw is embedded in the fastening groove, so that the unlocking plate is stable on the support frame, making it easy for the staff to remove the installation device from the cable.

[0027] Optionally, the unlocking plate has an arc rod that cooperates with the rotating shaft of the lower roller, and the inner arc surface of the arc rod abuts against the rotating shaft of the lower roller.

[0028] By adopting the above technical solution, when the unlocking plate is in use, the inner arc surface of the arc rod abuts against the rotating shaft of the lower roller, causing the unlocking plate to rotate on the rotating shaft of the lower roller.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. After the vibration damper is connected to the insulator string by the pull rope, the vibration damper is more stable on the cable and is less likely to slip on the cable.

[0031] 2. By compressing the spring and applying it to the force transmission plate, which in turn applies it to the shaft of the lower roller, the lower roller always tends to move closer to the upper roller. When the installation device is in use, the upper roller comes into contact with the cable, and the compression spring causes the lower roller to also come into contact with the cable, thus making the installation device more stable on the cable.

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1-15 This application will be described in further detail.

[0049] This application discloses a vibration damper, which is used to install on outdoor high-voltage power cables to reduce cable vibration; both ends of the cable are connected to power poles or power towers, and insulator strings 5 ​​are also provided at both ends of the cable.

[0050] Reference Figure 1 and Figure 2 The vibration damper includes two clamping plates 1, a connecting rod 2, an elastic rod 3, two hammer bodies 4, and a pull rope 13. The two clamping plates 1 are arranged opposite each other to form a clamping cavity 11 for the cable to be inserted. The cable is clamped by the clamping plates 1, and screws are passed through the clamping plates 1 to lock the two clamping plates 1. One end of the connecting rod 2 is fixedly connected to the two clamping plates 1, and the other end is fixedly connected to the middle of the elastic rod 3. The clamping plates 1 and the elastic rod 3 are connected by the connecting rod 2. The two hammer bodies 4 are respectively fixedly connected to the two ends of the elastic rod 3.

[0051] See Figure 2 and Figure 3The end of the clamp 1 away from the connecting rod 2 is bent away from the other clamp 1, thus forming a rope hole 12; one end of the pull rope 13 is fixedly connected to the insulator string 5, and the other end passes through the two rope holes 12 and is fixed by a nut, so that the pull rope 13 is fixedly connected to the anti-vibration hammer.

[0052] When installing the vibration damper, embed the cable into the clamping cavity 11, and then insert screws through the clamping plates 1 to lock the two clamping plates 1 in place.

[0053] This embodiment also discloses an installation device for a vibration damper, which is used to install the vibration damper onto a cable.

[0054] The installation location and number of vibration dampers vary for each cable, influenced by factors such as cable length and environmental conditions. Longer cables and those in windy environments require more dampers. Because vibration dampers are heavy, workers can only carry a limited number. When the number of dampers to be installed exceeds the number carried, workers need to make multiple trips to complete the installation. The vibration damper installation device disclosed in this application can connect to the cable and move along it. Workers can place the dampers on the device, which then moves them along the cable. This allows workers to carry all required dampers at once and install them on the cable simultaneously, improving work efficiency.

[0055] See Figure 4 and Figure 5 The installation device includes a frame 6 and a support frame 7. The support frame 7 is rotatably connected to the frame 6. The frame 6 is rotatably mounted with two upper rollers 61, which are spaced apart along the length of the frame 6. The support frame 7 has an installation cavity 71 inside, and the support frame 7 is rotatably mounted with two lower rollers 72 inside the installation cavity 71. The two lower rollers 72 are spaced apart along the length of the support frame 7, and the two lower rollers 72 correspond one-to-one with the two upper rollers 61.

[0056] See Figure 6 and Figure 7 Furthermore, the scaffold 6 has a first side plate 62 and a second side plate 63, which are arranged parallel to each other and are located on both sides of the upper roller 61. The support frame 7 has a rotating plate 73 and a locking plate 74, which are arranged parallel to each other and are located on both sides of the lower roller 72. The rotating plate 73 is rotatably connected to the first side plate 62 via a rotating shaft 731, and the support frame 7 rotates relative to the scaffold 6 via the rotating shaft 731, causing the support frame 7 to flip on the scaffold 6.

[0057] In addition, the locking plate 74 is integrally provided with a positioning block 741, and the second side plate 63 is provided with a positioning groove 631 for the positioning block 741 to be inserted. The positioning block 741 is provided with a locking screw 742, which passes through the positioning block 741 and enters the second side plate 63. The locking plate 74 and the second side plate 63 are fixed by the locking screw 742.

[0058] When the installation device is used on the cable, the support frame 7 is rotated in advance. The support frame 7 is rotated to one side of the bracket 6 via the rotating shaft 731, so that the support frame 7 and the bracket 6 are offset. Then the bracket 6 is placed on the cable, and both upper rollers 61 are in contact with the cable. Then the support frame 7 is rotated again, so that the support frame 7 is rotated to the bottom of the bracket 6, and the lower roller 72 is in contact with the cable. The action of the upper rollers 61 and the lower rollers 72 allows the installation device to move on the cable. At the same time, the positioning block 741 is embedded in the positioning groove 631, and the locking screw 742 is inserted through the positioning block 741. The locking screw 742 is screwed into the second side plate 63, so that the support frame 7 and the bracket 6 are relatively fixed, making it difficult for the support frame 7 to rotate.

[0059] See Figure 8 , Figure 9 and Figure 10 The support frame 7 is equipped with a roller clamping assembly 8, which abuts against the rotating shaft 721 of the lower roller 72, so that the lower roller 72 always has a tendency to move towards the upper roller 61. The roller clamping assembly 8 includes a compression spring 81 and a force transmission plate 82, both located within the mounting cavity 71. The force transmission plate 82 abuts against the rotating shaft 721 of the lower roller 72. One end of the compression spring 81 abuts against the cavity wall of the mounting cavity 71, and the other end abuts against the side of the force transmission plate 82 away from the rotating shaft 721. The compression spring 81 ensures that the force transmission plate 82 is always in contact with the rotating shaft 721. Simultaneously, the compression spring 81 pushes the force transmission plate 82, which in turn pushes the rotating shaft 721, causing the lower roller 72 to have a constant tendency to move towards the upper roller 61. When the mounting device is connected to a cable, the lower roller 72 abuts against the cable. The compression spring 81 pushes the lower roller 72, ensuring that the lower roller 72 is always in contact with the cable, thus making the mounting device more stable on the cable and allowing for smoother movement of the mounting device on the cable.

[0060] See Figure 10 and Figure 11To make the compression spring 81 more stable on the support frame 7, the cavity wall of the mounting cavity 71 is provided with a spring groove 75. The rotating shaft 721 of the lower roller 72 rotates through the spring groove 75, and the rotating shaft 721 of the lower roller 72 can slide within the spring groove 75. The force transmission plate 82 is also located within the spring groove 75. Similarly, the force transmission plate 82 can also slide within the spring groove 75 along the length direction of the spring groove 75. The compression spring 81 is located within the spring groove 75, and the compression spring 81 can extend and retract within the spring groove 75. The restriction of the spring groove 75 makes the compression spring 81 less prone to radial bending, thereby improving the service life of the compression spring 81.

[0061] See Figure 11 and Figure 12 The support frame 7 is equipped with a support assembly 9, which supports the vibration damper and places it on the support frame 7. The support assembly 9 includes a support plate 91, which is placed horizontally in the mounting cavity 71. The vibration damper is placed on the support plate 91 and supported by the support plate 91. To prevent the vibration damper from moving on the support plate 91, two through slots 92 are provided on the support plate 91 for the hammer body 4 of the vibration damper to enter. When the vibration damper is placed on the support plate 91, the two hammer bodies 4 are respectively placed into the two through slots 92, and the restriction of the slot walls makes it difficult for the vibration damper to move on the support plate 91.

[0062] The support assembly 9 also includes a clamping screw 93, which is inserted into the support frame 7 from the side away from the scaffold 6. The clamping screw 93 is threadedly connected to the support frame 7, and the end plate 91 of the clamping screw 93 abuts against it. The height of the plate 91 in the support frame 7 is adjusted by adjusting the length of the clamping screw 93 screwed into the support frame 7.

[0063] When installing the vibration damper, first place the vibration damper on the support plate 91, and move the vibration damper by the installation device. When the installation device moves to the position where the vibration damper is installed, stop the installation device, and then turn the clamping screw 93. The clamping screw 93 is screwed into the support frame 7. At the same time, the clamping screw 93 pushes the support plate 91 to move closer to the cable until the clamping plate 1 of the vibration damper is put on the cable and the cable enters the clamping cavity 11. After that, remove the installation device from the cable and then insert the screw into the clamping plate 1. Lock the clamping plate 1 with the screw to fix the vibration damper to the cable.

[0064] The force transmission plate 82 protrudes outward from the spring groove 75 to form a pressure plate 83. The pressure plate 83 also abuts against the rotating shaft 721 of the lower roller 72. The pressure plate 83 and the force transmission plate 82 can be connected by glue or can be integrally set. In order to improve the structural strength between the pressure plate 83 and the force transmission plate 82, in this embodiment the pressure plate 83 and the force transmission plate 82 are integrally set.

[0065] Furthermore, the support plate 91 includes a supporting portion 911 and four abutting portions 912. The abutting portions 912 are integrally connected to the supporting portion 911, and the four abutting portions 912 are located at the four corners of the supporting portion 911. The supporting portion 911 is used to support the vibration damper, and the abutting portions 912 are located below the pressure plate 83. The end of the clamping screw 93 abuts against the side of the abutting portion 912 away from the pressure plate 83. When the vibration damper is installed and the clamping screw 93 is tightened, the clamping screw 93 pushes the abutting portion 912 to abut against the pressure plate 83, and pushes the pressure plate 83 to press against the rotating shaft 721 of the lower roller 72, making it difficult for the rotating shaft 721 of the lower roller 72 to rotate within the spring groove 75, thereby making it difficult for the lower roller 72 to move on the cable, making the vibration damper installation more stable.

[0066] See Figure 13 To ensure the stability of the clamping screw 93 acting on the abutment portion 912, the abutment portion 912 is provided with a fixing groove 913. When the clamping screw 93 abuts against the abutment portion 912, the end of the clamping screw 93 is embedded in the fixing groove 913. The clamping screw 93 is not easy to slide on the abutment portion 912 due to the restriction of the groove wall of the fixing groove 913.

[0067] See Figure 14 and Figure 15 The support frame 7 is equipped with an unlocking plate 76, which has two integrally formed arc rods 77. The two arc rods 77 are arranged opposite each other, and each arc rod 77 has an outer arc surface 771 and an inner arc surface 772. The inner arc surface 772 of the arc rod 77 abuts against the rotating shaft 721 of the lower roller 72, so that the arc rod 77 rests on the rotating shaft 721 of the lower roller 72. The unlocking plate 76 has a clearance groove 761 for the lower roller 72 to enter, so that the unlocking plate 76 rests on the rotating shaft 721 of the lower roller 72 and does not easily interfere with the lower roller 72. The end of the unlocking plate 76 away from the arc rods 77 has a locking groove 762, which is elongated.

[0068] After the vibration damper is installed, loosen the clamping screw 93 so that it is turned away from the cable, so that the abutment part 912 no longer presses against the pressure plate 83, and the pressure plate 83 no longer presses against the shaft 721 of the lower roller 72. Then pull the unlocking plate 76, which pulls the shaft 721 of the lower roller 72 away from the upper roller 61, so that the lower roller 72 is no longer in contact with the cable, and there is a distance between the lower roller 72 and the cable, so that it is convenient to rotate the support frame 7. Rotate the support frame 7 to one side of the bracket 6 so that the installation device can be removed from the cable. After the unlocking plate 76 pulls the shaft 721 of the lower roller 72 away from the upper roller 61, fasten the end of the unlocking plate 76 away from the lower roller 72 onto the clamping screw 93. The clamping screw 93 is embedded in the fastening groove 762, so that the unlocking plate 76 is stable on the support frame 7, making it easy for the staff to remove the installation device from the cable.

[0069] The implementation principle of the vibration damper installation device in this application embodiment is as follows: Workers place the vibration damper to be installed on the installation device and connect the installation device to the cable. Generally, there are multiple installation devices, and workers move these devices along the cable. When the location for installation of the vibration damper is reached, the vibration damper is installed onto the cable. The installation device is then removed from the cable and installed at another location on the cable, ensuring that the installed vibration damper does not interfere with the movement of the installation device. Afterwards, the vibration damper near the insulator string 5 is connected to the pull rope 13, thus connecting the vibration damper to the insulator string 5.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
