[0002] Spacer bars are devices installed on split conductors to fix the spacing between them, prevent whipping, and suppress aerobatic vibrations and span oscillations. Spacer bars are classified by the number of split conductors (two-split, four-split, six-split, eight-split, etc.) and by installation method (clamp type, hinged type, etc.). When installing on transmission towers, the appropriate type of spacer bar must be selected based on the installation location and the differences in connecting components.

[0003] Currently, the spacers used on steel pipe skeleton sections are mostly clamp-type, utilizing the cooperation of split lever arms and wire clamps to stably install the spacers on the steel pipe skeleton section, providing support and limiting for the transmission lines. However, the following problems exist in actual use: because the wire clamps need to be tightened with bolts, operators must tighten the bolts or screws at height and carry wrenches and other tools, resulting in long operation time, high physical exertion, and reduced installation efficiency.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1 , Figure 2 and Figure 6As shown, this is a schematic diagram of the structure of the clamp-type spacer bar for the steel pipe skeleton section of the multi-split conductor cage jumper in this embodiment. The spacer bar includes a main frame 1, split arms 2, and clamps 3. The main frame 1 is installed on the side of the clamps 3, and the split arms 2 are installed at equal intervals on the outside of the main frame 1. A connecting mechanism 4 is provided on the split arms 2. The clamps 3 include a sleeve 31, a pressing screw 32, a pressing nut 33, a mounting block 34, and a mounting screw 35. The sleeves 31 are symmetrically arranged on the side of the main frame 1. The pressing screw 32 is threaded on the ends of the two sleeves 31. The pressing nut 33 is threaded on the end of the pressing screw 32. The mounting blocks 34 are symmetrically installed on the side of the sleeves 31. The mounting screw 35 is threaded on the mounting blocks 34 and threadedly connected to the main frame 1.

[0027] In use, the two sets of sockets 31 are first attached to the side of the main frame 1. Then, with the cooperation of the mounting block 34 and the mounting screw 35, the clamp 3 and the main frame 1 are connected to ensure the overall stability of the main frame 1. After that, the two sets of sockets 31 are attached together, and the compression screw 32 is passed through the end of the socket 31 at the same time. The two sets of sockets 31 are reinforced and locked by the use of the compression nut 33, so as to realize the fixation and assembly of the spacer bar as a whole component. The connection mechanism 4 is used to support and position multiple sets of transmission lines to prevent the transmission lines from colliding with each other under the action of wind and to ensure the safety of the transmission lines during use.

[0028] From the appendix Figure 3 As shown, this is a schematic diagram of the connecting mechanism 4 in this embodiment. The connecting mechanism 4 includes a mounting base 41, a fixed clamp 42, a rotating clamp 43, a mating block 44, a locking component 45, and a sleeve component 46. The splitting arm 2 is provided with a mounting base 41. A fixed clamp 42 is installed on one side of the upper surface of the mounting base 41, and a closing groove is opened on the other side of the upper surface of the mounting base 41. A rotating clamp 43 is rotatably installed at the end of the fixed clamp 42. A mating block 44 is fixedly installed at the end of the rotating clamp 43. A locking component 45 for locking the mating block 44 is installed on the side of the mounting base 41, and a sleeve component 46 is installed at the end of the locking component 45.

[0029] During use, rotating the clamp 43 causes the inner wall of the fixed clamp 42 to fit against the outside of the transmission line. Then, rotating the clamp 43 causes the mating block 44 to rotate into the closed groove, driving the fixed clamp 42 and the rotating clamp 43 to fit against the outer surface of the transmission line, thereby locking the position of the spacer end. The connecting mechanism 4 is provided in multiple sets according to the number of transmission lines. Each set of connecting mechanisms 4 corresponds to a single transmission line, supporting and limiting the position of the transmission line.

[0030] From the appendix Figure 4As shown, this is a schematic diagram of the positioning component 45 in this embodiment. The positioning component 45 includes a side shell 451, a positioning ladder plate 452, a connector 453, and a spring assembly 454. The side shell 451 is mounted on the side of the mounting base 41. A sliding groove is provided inside the side shell 451, which communicates with a closed groove. The positioning ladder plate 452 is slidably installed inside the sliding groove and enters the closed groove. A connector 453 is installed at the end of the positioning ladder plate 452. A spring assembly 454 is sleeved on the outside of the connector 453. The end of the spring assembly 454 is connected to the inner wall of the side shell 451, and the other end of the spring assembly 454 is connected to the end of the positioning ladder plate 452.

[0031] During use, the mating block 44 rotates into the closed groove. At this time, the locking ladder plate 452 in the closed groove is squeezed and retracts into the moving groove, so that the mating block 44 is locked into the gap between the closed groove and the locking ladder plate 452, locking the angle and position of the rotating clamp 43. When the locking ladder plate 452 is squeezed, the spring assembly 454 enters the storage state, so that after the mating block 44 is no longer in contact with the locking ladder plate 452, the spring assembly 454 releases its accumulated elastic force, allowing the locking ladder plate 452 to re-enter the closed groove and lock the position of the mating block 44.

[0032] From the appendix Figure 5 As shown, it is a structural schematic diagram of the sleeve assembly 46 in this embodiment. The sleeve assembly 46 includes a rotating frame 461, a collar 462 and a limiting frame 463. The rotating frame 461 is installed at the end of the connector 453, the collar 462 is installed at the end of the rotating frame 461, and the limiting frame 463 is installed on the side of the mounting base 41 and at the opening of the side of the closed groove.

[0033] When the mating block 44 is inserted into the gap between the locking ladder plate 452 and the closing groove during use, the locking ladder plate 452 is slid away from the moving groove by pressing the connecting piece 453, causing the collar 462 to move closer to the limiting frame 463. At this time, the spring assembly 454 is stretched until the collar 462 is fitted outside the limiting frame 463. The position of the collar 462 is locked by the protrusion at the end of the limiting frame 463, and the position of the rotating clamp 43 is further locked to prevent the mating block 44 from popping out of the closing groove.

[0034] From the appendix Figure 3 As shown, a connecting seat 5 is installed at the bottom of the mounting base 41. The connecting seat 5 consists of a connecting seat and bolts. The connecting seat is installed at the bottom of the mounting base 41 and is connected to the splitting lever arm 2 by bolts.

[0035] In use, the mounting base 41 is fitted onto the end of the split lever arm 2, allowing the connecting base to mate with the split lever arm 2. Then, by using bolts, the mounting base 41 is installed as a whole at the end of the split lever arm 2, thereby locking the overall position of the connecting mechanism 4.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
