Abstract
Description
Technical Field
[0001] This application relates to the field of equalizing ring technology, specifically to a lightweight, detachable high-pressure equalizing ring. Background Technology
[0002] Equalizing rings are a type of protective fitting used in all string-type insulators and hardware in 330kV and above voltage level lines and substations. They can effectively improve the surface potential gradient of insulators and prevent them from aging rapidly.
[0003] Chinese patent document CN221057212U discloses a detachable equalizing ring, specifically disclosing the ring body and connecting parts. The connecting parts are connected to the ring body via a fixing structure. The fixing structure has a locking block surrounding the ring body, with connecting blocks integrally connected to both ends of the locking block. The connecting block is limited by a limiting structure, and the connecting block is fixed to the connecting parts by bolts. A locking structure is provided inside the ring body, and the locking block of the fixing structure is locked by the locking structure. The advantages of this utility model are: the ring body and the connecting parts are fixedly connected by the fixing structure; the connecting block connected to the locking block of the fixing structure is positioned between the C-shaped frame and the support foot, allowing for faster connection between the connecting block and the support foot; the locking block between the locking block and the ring body via the fixing block makes the overall structure of the equalizing ring more robust, and installation and disassembly are convenient and quick.
[0004] However, the installation and fixing method of this utility model is too cumbersome. The installer needs to hold the ring body with one hand and tighten it with the other, which increases the difficulty of working at heights. In addition, the installation is not very secure and there is a risk of it falling off after long-term use. Utility Model Content
[0005] To overcome the problems of complex installation and poor stability of existing equalizing rings, this application provides a lightweight, detachable high-pressure equalizing ring.
[0006] This application adopts the following technical solution: a lightweight detachable high-pressure equalizing ring, assembled on a mounting post, including a ring body, and a pair of mounting rods are provided on the inner wall of the ring body;
[0007] Two clips are clamped to the outside of the mounting post and locked in place by a first bolt;
[0008] Two locking blocks are respectively arranged on the two clamping pieces. The locking blocks have a limiting groove extending vertically on the side facing the mounting rod. The mounting rod is adapted to be placed in the limiting groove and locked by the second bolt.
[0009] Optionally, the top of the limiting groove is connected to the top of the locking block, and the length of the limiting groove is less than the height of the locking block;
[0010] The clamp is semi-circular, and a fixing ear is provided on the outer side of the clamp. The fixing ears of the two clamps fit together, and the first bolt is used to lock the fixing ear.
[0011] Optionally, the bottom of the limiting groove is provided with a threaded hole, and one end of the mounting rod located in the limiting groove is flat and has a through hole. The through hole is coaxially arranged with the threaded hole, and the second bolt passes through the through hole and is adapted to be screwed into the threaded hole.
[0012] Optionally, the top of the limiting groove is provided with a flared opening, which opens upward toward the locking block.
[0013] Optionally, a pair of sliding grooves are provided on the inner wall of the limiting groove, and at least one limiting block is adapted to be provided in the limiting groove. A slider is provided on both sides of the limiting block. The slider is adapted to be inserted into the sliding groove and can slide in the sliding groove. The limiting block is used to support or cover the end of the mounting rod.
[0014] Optionally, when the limiting block is located at the bottom of the mounting rod, the limiting block is used to support the mounting rod.
[0015] Optionally, when the limiting block is located at the top of the mounting rod, the limiting block is used to cover the end of the mounting rod.
[0016] Optionally, the top of the limiting block is provided with a countersunk hole coaxial with the perforation.
[0017] Compared with the prior art, this application achieves the limiting effect of the installation rod by opening a limiting groove on the locking block, realizing the initial fixation of the ring body, which makes it easier for the installer to use both hands to finally fix the ring body, optimizes the installation steps, effectively improves the installation efficiency and the installation firmness.

[0023] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0024] like Figure 1-4 As shown, a lightweight, detachable high-pressure equalizing ring is assembled on a mounting post 1. The mounting post 1 is set at the installation site and includes a ring body 2. A pair of mounting rods 3 are provided on the inner wall of the ring body 2.
[0025] Clip 4, two clips 4 are clamped on the outside of the mounting post 1 and locked in place by the first bolt 41;
[0026] Locking blocks 5, two locking blocks 5 are set on two clamping pieces 4 in a one-to-one correspondence. The side of the locking block 5 facing the mounting rod 3 is provided with a limiting groove 51 extending in the vertical direction. The mounting rod 3 is placed in the limiting groove 51 and locked by the second bolt 52.
[0027] During installation, the two clamping pieces 4 are first installed on the mounting posts 1 and then tightened with the first bolt 41, so that the clamping pieces 4 can reliably clamp the mounting posts 1. Then, the ring body 2 is placed on the outside of the mounting posts 1, and the two mounting posts 1 are aligned with the two limiting grooves 51 one by one. At this time, the ring body 2 is lowered, and the mounting posts 1 can be slid into the limiting grooves 51. In this way, the ring body 2 is initially fixed. The installer does not need to hold the ring body 2 to perform the tightening operation of the second bolt 52. The installation steps are simple, which is convenient for the installer to work at height and effectively improves the installation efficiency.
[0028] The top of the limiting groove 51 is connected to the top of the locking block 5, and the length of the limiting groove 51 is less than the height of the locking block 5; the clamping piece 4 is semi-circular, and the outer side of the clamping piece 4 is provided with a fixing ear 42. The fixing ears 42 of the two clamping pieces 4 fit together, and the first bolt 41 is used to lock the fixing ear 42.
[0029] The limiting groove 51 is opened downward from the top of the locking block 5 and does not penetrate the locking block 5 vertically. Simultaneously, the limiting groove 51 communicates with the outer wall of the locking block 5 facing the mounting rod 3. This allows the horizontally positioned mounting rod 3 to slide downward into the limiting groove 51. When the mounting rod 3 reaches the lowest position of the limiting groove 51, its position is relatively fixed. In other words, after the two locking blocks 5 correspondingly limit the two mounting rods 3, the mounting rods 3 can only move upward and cannot continue to move downward or rotate. This allows the installer to complete the subsequent locking operation without manually limiting the ring body 2, effectively improving safety and installation efficiency. The first bolt 41 includes a nut. Through the cooperation of the first bolt 41 and the nut, the two fixing ears 42 are locked, ensuring that the clamping piece 4 can form a clamping structure, thus providing a foundation for the assembly of the ring body 2.
[0030] The bottom of the limiting groove 51 is provided with a threaded hole 53. The end of the mounting rod 3 located in the limiting groove 51 is flat and has a through hole 30. The through hole 30 is coaxially arranged with the threaded hole 53. The second bolt 52 passes through the through hole 30 and is screwed into the threaded hole 53.
[0031] The end of the mounting rod 3 is flat, which allows it to fit completely against the inner wall of the limiting groove 51, preventing the mounting rod 3 from moving or rotating within the limiting groove 51. Moreover, the flat shape increases the contact area with the limiting groove 51, thereby achieving a pressing effect on the end of the mounting rod 3 after the second bolt 52 is screwed into the through hole 30 and the threaded hole 53.
[0032] The top of the limiting groove 51 is provided with a flared opening 54, which opens upwards toward the locking block 5. The flared opening 54 facilitates the quick insertion of the two mounting rods 3 into the limiting groove 51 in sequence, minimizing the installation difficulty of the ring 2.
[0033] The inner wall of the limiting groove 51 is provided with a pair of sliding grooves 55. At least one limiting block 6 is adapted to be provided in the limiting groove 51. A slider 61 is provided on both sides of the limiting block 6. The slider 61 is adapted to be inserted into the sliding groove 55 and can slide in the sliding groove 55. The limiting block 6 is used to support or cover the end of the mounting rod 3.
[0034] Under the limiting action of the slider 61, the limiting block 6 can only slide into or out of the limiting groove 51 in the vertical direction. When the installation height of the clamping piece 4 and the locking block 5 does not need to be adjusted, after the mounting rod 3 is placed into the limiting groove 51, the installation height of the ring body 2 meets the design requirements. At this time, the limiting block 6 is slid into the limiting groove 51 and pressed on the top of the mounting rod 3. Since the top of the limiting block 6 is provided with a countersunk hole 62 coaxial with the through hole 30, after the second bolt 52 is passed through the limiting block 6 and the mounting rod 3 and screwed into the threaded hole 53, the cooperation between the second bolt 52 and the limiting block 6 can reliably press the mounting rod 3, effectively improving the locking firmness between the mounting rod 3 and the locking block 5, thereby improving the assembly stability of the ring body 2. After the clamp 4 is installed and the mounting rod 3 is placed in the limiting groove 51, if the height of the ring 2 needs to be adjusted, there is no need to rotate the first bolt 41. Simply lift the ring 2, remove the mounting rod 3 from the limiting groove 51, and then insert the corresponding number of limiting blocks 6 into the limiting groove 51 according to the required adjustment. At this time, the limiting blocks 6 are located at the bottom of the mounting rod 3 and provide support for the mounting rod 3. Finally, the second bolt 52 of appropriate length can be screwed in directly, or a limiting block 6 can be placed on the top of the mounting rod 3 before screwing in the second bolt 52 to adjust and fix the height of the mounting rod 3, thus achieving fine adjustment of the height of the ring 2. This adjustment method only requires sliding in different numbers of limiting blocks 6, without the need to rotate the first bolt 41 or the second bolt 52, reducing the difficulty of operation and improving the efficiency and flexibility of installation and adjustment.
[0035] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
