Description

Technical Field

[0001] The utility model relates to the technical field of overhead line fixing, in particular to a standardized tightening device for overhead lines. Background Art

[0002] The overhead line is fixed on the insulator by multiple bolts. The insulator is first placed in the groove on the top surface, and then fixed with multiple bolts and fixing parts at both ends of the insulator extending out of the groove. The operation is relatively cumbersome and requires more professional operators to operate. The installation and fixing time is time-consuming and inefficient.

[0003] The existing fixation of overhead lines and insulator bodies requires a long time of operation and has low work efficiency. For example, the conductor and cable fixing support device with publication number CN103107494A can fix the conductor or cable on the pole through an insulating operating rod when the conductor or cable is energized, avoiding the operator holding the insulating operating rod to fix the conductor or cable, reducing the labor intensity between operators, preventing the live conductor or cable from short-circuiting and contacting the operator when the live conductor or cable swings, improving the safety of power construction, and is safer when in contact with the insulator. When the cable or conductor is installed on the insulator, it is often installed without power, and the method of inserting the plug accurately into the slot is still difficult to operate compared to the method of pulling the spring open, and the method of pulling the spring open is simpler.

[0004] Therefore, it is necessary to invent a standardized overhead line tightening device to solve the above problems. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 A standardized tensioning device for overhead lines shown in the figure comprises an insulator body 1, a fixed ring part 2 and a hand fixing part 3. The fixed ring part 2 is sleeved on the insulator body 1. The fixed ring part 2 is designed to be open on one side and is fixed by a No. 1 fixing bolt 4 between the openings. The hand fixing part 3 is fixedly connected to the fixed ring part 2. A limiting groove 5 is provided on the side of the fixed ring part 2. A fixing rod 6 is fixedly connected to the front of the limiting groove 5. One end of a spring 7 is fixedly connected in the limiting groove 5. The other end of the spring 7 is fixedly connected to a moving rod 8. The moving rod 8 is fixedly connected to a fixing plate 9. The movement of the fixing plate 9 clamps the conductor between the top surface groove and the fixing plate 9.

[0024] A clamping force is formed between the conductor placed in the top groove of the insulator body 1 and the movable and adjustable fixing plate 9, so that the conductor is initially clamped and fixed, and the clamping operation is also relatively convenient and simple.

[0025] A rotating shaft 10 is arranged at the top of the fixing plate 9, and an arc plate 11 is rotatably connected to the rotating shaft 10. A hole is opened on the arc plate 11, and a hole is also opened on the fixing plate 9. The positions of the holes correspond to the positions of the holes on the arc plate 11, and the diameters are the same. The grooves opened on the hand fixing piece 3 and the top of the insulator body 1 are perpendicular to each other.

[0026] The wire is further fixed by the arc plate 11 installed on the fixing plate 9 on the moving rod 8, and the wire is clamped between the two arc plates 11. The whole operation is relatively simple and convenient.

[0027] There are two limit grooves 5, which are mirror-symmetrically distributed about the center of the fixed ring member 2, and springs 7 and moving rods 8 are arranged in the two limit grooves 5. There are two fixed plates 9, which have the same shape and size, and are both provided with rotating shafts 10. The rotating shafts 10 are both rotatably connected to arc plates 11, and the curvature of the arc plates 11 is also the same.

[0028] The movable mechanism in the entire limiting groove 5 is easy and quick to operate. After the wire is initially fixed, it is convenient to further fix it. After being fixed, the position of the entire fixed ring 2 can also be adjusted. After adjustment, it is fixed with a No. 1 fixing bolt 4.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the utility model, firstly, the wire is roughly placed in the groove at the top of the insulator body 1, and the fixing ring 2 is sleeved onto the insulator body 1 by using the hand fixing piece 3, and the position of the hand fixing piece 3 is adjusted by the elastic force of the spring 7 in the limiting groove 5, and the hand fixing piece 3 is pulled according to the capacity of the wire;

[0031] Refer to the instruction manual Figure 3-5 When using the utility model, the wire is initially clamped by adjusting the distance of the hand fixing member 3, and is fixed by the second fixing bolt 12 within the range of the wire being clamped by the rotating arc plate 11, so that the wire is fixed in position at both ends of the insulator body 1, and the entire fixing ring 2 is highly practical.
