Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a pre-twisted hardware with a wear-resistant structure. Background Art

[0002] Guy wire fittings are used to connect, secure, and adjust guy wires between the tower and the ground anchor. Guy wires are made of galvanized steel strands and include NLY-type clamps, wedge-type clamps, UT-type clamps, and double-guy wire tie plates.

[0003] Most of the pre-twisted wire harnesses in the existing technology are not convenient for convenient adjustment of tension and cannot adapt to changes in different environments and load conditions. This may cause uneven force on the pole tower structure and increase the risk of the pole tower overturning or damage. Secondly, under different temperature conditions, the wire may bear additional load. If the tension cannot be adjusted, it is easy to cause wire overload, accelerate its wear and aging, and shorten its service life. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a pre-twisted hardware with a wear-resistant structure, comprising:

[0023] A heart-shaped ring 1 is provided with a pre-twisted wire 2 inside the heart-shaped ring 1. Through holes 4 are provided on both sides of the heart-shaped ring 1. Bolts 3 are provided through the through holes 4. A first nut 5 is sleeved on the bolt 3. The pre-twisted wire 2 can be disassembled by unscrewing the first nut 5 and then removing the bolt 3. The operation is simple, fast and efficient.

[0024] The adjustment assembly includes a first U-shaped ring 6, a threaded barrel 8, a threaded rod 9 and an annular column 10. A second U-shaped ring 14 is sleeved on the first U-shaped ring 6. An annular block 15 is fixedly provided at both ends of the second U-shaped ring 14. The second U-shaped ring 14 and the two annular blocks 15 are existing technologies and are used to fix to the tower pole;

[0025] The two ends of the first U-shaped ring 6 are fixedly provided with a fixing plate 7, and the threaded cylinder 8 passes through the fixing plate 7 and is rotatably connected. A rotating block 12 is fixedly provided on the threaded cylinder 8, and the rotating block 12 is arranged on the outer side of the fixing plate 7. The rotating block 12 is arranged in a hexagonal prism shape, which can facilitate the staff to use tools such as wrenches to rotate the threaded cylinder 8. The threaded rod 9 passes through the threaded cylinder 8 and is threadedly connected thereto. The annular column 10 is fixedly provided on the outer end of the threaded rod 9, and the annular column 10 is sleeved on the bolt 3. The other end of the threaded rod 9 is fixedly provided with a supporting plate 11. Both ends of the first U-shaped ring 6 pass through the supporting plate 11 and are slidably arranged. A second nut 13 is sleeved on the threaded rod 9, and the second nut 13 is threadedly connected to the threaded rod 9. The second nut 13 is arranged between the support plate 11 and the threaded cylinder 8. When the second nut 13 is rotated to abut against the inner side of the threaded cylinder 8, the threaded cylinder 8 is limited to prevent the threaded cylinder 8 from being driven to rotate, thereby preventing the threaded rod 9 from loosening and improving stability.

[0026] A first wear-resistant part 16 is fixedly provided on the first U-shaped ring 6, the annular column 10 and the second U-shaped ring 14. A second wear-resistant part 17 is fixedly provided on the inner side of the heart-shaped ring 1. The first wear-resistant part 16 and the second wear-resistant part 17 are made of wear-resistant materials, which can play a wear-resistant role and extend the service life.

[0027] The detailed working process of this utility model is as follows:

[0028] 1. During installation, first pass the pre-twisted wire 2 through the heart-shaped ring 1, then place the annular column 10 into the heart-shaped ring 1, and pass the bolt 3 through the two through holes 4 and the annular column 10, and tighten the first bolt 3 with the first nut 5 to complete the fixation;

[0029] 2. Then, use a tool to rotate the rotating block 12 to drive the threaded barrel 8 to rotate, and the annular column 10 can be driven to move through the threaded rod 9, thereby adjusting the tension of the pre-twisted wire 2. After adjusting to the appropriate tension, the threaded barrel 8 can be tightened by rotating the second nut 13 to limit the position.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
