Description

Technical Field

[0001] The utility model relates to the field of spacer bars, in particular to a spacer bar which is easy to install. Background Art

[0002] Spacers are hardware that are installed on split conductors to fix the spacing between each split conductor to prevent the conductors from whipping each other, suppress breeze vibration and sub-span oscillation. They are mainly used in ultra-high voltage and ultra-high voltage transmission lines to limit the relative movement between sub-conductors and maintain the geometric shape of the split conductors under normal operation. Spacers can be divided into damping type spacers and non-damping type spacers according to their working characteristics. Among them, damping type spacers use rubber as a damping material at the movable joint to consume the vibration energy of the conductor and produce a damping effect on the vibration of the conductor.

[0003] After massive searches, it was found that the prior art publication number is CN212210435U, which discloses a spacer that is easy to install. This patent is fixed to the spacer body by connecting ribs. The utility model is cleverly designed. The installer only needs to pre-install multiple spacers on the cables on an electric tower, then pull each spacer to a specified position, start the locking structure to tighten the fastening structure, and thus fix the spacer body. It is safe and convenient to use, greatly improves the installation efficiency, and avoids the high-altitude drop of parts. However, in this patent, when the staff installs the spacer body on the line at high altitude, the staff needs to hold the spacer body with one hand and then use the other hand to use bolts to fix multiple clamps on the line in sequence. The process is cumbersome and it is difficult to directly hang the spacer body on the line for installation. The installation effect is poor, which affects the staff's use of the spacer body. Therefore, based on the above search and combined with the prior art, the utility model proposes a spacer that is easy to install to solve the above problems. Utility Model Content

[0023] The mounting assembly 3 includes two support plates 18, which are rotatably connected to the top surfaces of the two support arms 2 located above, respectively. A steel wire rope 19 is wound around the outer circumferential wall of the support plate 18, one end of the steel wire rope 19 is fixedly installed with a limit hanging plate 25, one side of the inner side of the limit hanging plate 25 is fixedly installed with two positioning blocks 27, one side of the inner side of the limit hanging plate 25 is elastically connected with a baffle 29, one side of the inner side of the limit hanging plate 25 is fixedly installed with two springs 26, one end of the spring 26 is fixedly connected to one side of the baffle 29, and the baffle 2 9 is rotatably connected with two positioning blocks 27, connecting rollers 28 are fixedly installed on the top and bottom surfaces of the baffle 29, a circular through hole is opened on the top surface of the positioning block 27, the outer circumferential wall surface of the connecting roller 28 is rotatably connected with the inner circumferential wall surface of the circular through hole, a limiting block 31 for limiting is fixedly installed on one side of the baffle 29, the limiting block 31 is movably connected with the limiting hanging plate 25, a limiting hole 30 is opened on one side of the limiting hanging plate 25, the limiting block 31 is movably connected with the limiting hole 30, and a tensioning member for tightening the wire rope 19 is arranged on the top surface of the support arm 2;

[0024] The tensioning member includes two mounting blocks 24, both of which are fixedly mounted on the top surface of the support arm 2. Rotating columns 22 are fixedly mounted on both sides of the support disk 18. A circular through hole is opened on one side of the mounting block 24. The outer circular wall surface of the rotating column 22 is rotatably connected to the inner circular wall surface of the circular through hole. A torsion spring 23 is movably sleeved on the outer circular wall surface of the rotating column 22. One end of the torsion spring 23 is fixedly connected to one end of the support disk 18, and the other end of the torsion spring 23 is fixedly connected to one side of the mounting block 24. When the steel wire rope 19 on the support disk 18 is released, the torsion spring 23 will twist, and the torsion spring 23 will apply a reverse force to the support disk 18 and the steel wire rope 19, thereby tightening the steel wire rope 19.

[0025] Through the set spacer bar body 1, when the spacer bar body 1 is installed on the line for use, the staff picks up the limit hanging plate 25 and moves the limit hanging plate 25 outward. The limit hanging plate 25 moves outward to drive the wire rope 19 to move outward and at the same time makes the support plate 18 drive the rotating column 22 to rotate on the mounting block 24. The support plate 18 drives the rotating column 22 to rotate and also causes the torsion spring 23 to twist. The torsion of the torsion spring 23 provides a reverse force to the support plate 18 and tightens the wire rope 19. The staff squeezes the line with the baffle 29 on the limit hanging plate 25 so that the baffle 29 drives the connecting roller 28 to rotate inward on the positioning block 27 and at the same time makes the spring 26 compressed. The baffle 29 rotates inward to drive the limit block 31 to move inward to the outside of the limit hole 30 on the limit hanging plate 25, and as the line enters the inner part of the limit hanging plate 25 The part loses the squeezing of the line, and the force of the spring 26 makes the baffle 29 rotate outward and makes the limiting block 31 enter the limiting hole 30 on the limiting hanging plate 25. At this time, the baffle 29 can limit the line inside the limiting hanging plate 25. The two sets of limiting hanging plates 25 and the wire rope 19 located on the two upper support arms 2 can cooperate to hang the two spacer bar bodies 1 on the line, and then use the line to support the two spacer bar bodies 1, and then the staff will install the spacer bar body 1 suspended on the line. There is no need for the staff to hold the spacer bar body 1 with their hands while installing the spacer bar body 1 on the line with bolts. Compared with the existing technology, the installation is more convenient, and the installation effect of the spacer bar body 1 is achieved, which is convenient for the staff to install the spacer bar body 1 on the line.

[0027] Through the set spacer bar body 1, after the spacer bar body 1 is hung on the line, the staff rotates the second clamp 12 outward to make the line enter the first clamp 11 and the second clamp 12 and uses bolts to lock the line between the first clamp 11 and the second clamp 12, and then the staff rotates the threaded rod 13 to rotate the threaded hole 14 on the second clamp 12, and the rotation of the threaded rod 13 also makes the rubber plate 15 move forward inside the second clamp 12 until the rubber plate 15 abuts against the outer wall of the line, thereby further locking the line, and then locking the spacer bar body 1 on the line;

[0028] A plurality of movable holes 16 for supporting the rotation of the support arm 2 are provided on one side of the spacer rod body 1. Threaded columns 17 are fixedly installed on both sides of the support arm 2. The outer circumferential wall surface of the threaded column 17 is rotatably connected to the inner circumferential wall surface of the movable hole 16.
