Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line equipment, and in particular relates to a suspension wire clamp for a power transmission line. Background Art

[0002] The suspension clamp is used to fix the conductor on the insulator string of the straight pole tower, or to suspend the lightning arrester on the straight pole tower. It can also be used to support the transposed conductor on the transposed pole tower and fix the jumper of the tension angle pole tower. The suspension clamp retains the U-bolt style. It is composed of the bracket U-bolt, the clamp hull made of forgeable cast iron, and the pressure plate. This commonly used structure has a disadvantage. The suspension clamp has too many parts and the assembly is too complicated. The power transmission workers need to carry a lot of parts and tools during the high-altitude operation, which makes the work more troublesome and increases the risk. Utility Model Content

[0006] A rotating shaft rod 3 is rotatably connected to the left rotating shell 2 and the right rotating shell 6 in sequence, and anti-dropout covers 4 are installed at both ends of the rotating shaft rod 3; the left half ring 1 and the right half ring 5 are connected and fixed by the rotating shaft rod 3; the left half ring 1 and the right half ring 5 can rotate freely on the rotating shaft rod 3, and the anti-dropout cover 4 can effectively prevent the left half ring 1 and the right half ring 5 from falling off during use.

[0007] A left fixing plate 9 is fixedly connected to the top of the left half ring 1, and a right fixing plate 12 symmetrical to the left fixing plate 9 is fixedly connected to the top of the right half ring 5. A first screw 10 is movably installed through the left fixing plate 9 and the right fixing plate 12, and one end of the first screw 10 is threadedly connected to a threaded cap 11;

[0008] A connecting ring 13 is sleeved on the first screw 10 between the left fixing plate 9 and the right fixing plate 12, a U-shaped positioning buckle 14 is arranged above the connecting ring 13, and a second screw 15 is movably mounted on the U-shaped positioning buckle 14. The wire clamp can be fixed by the U-shaped positioning buckle 14 so that the wire clamp is fixed to a desired position.

[0009] Furthermore, the U-shaped positioning buckle 14 is sleeved on the connecting ring 13 with its opening facing upward.

[0010] Furthermore, threaded holes are provided in the middle and upper parts of the two side walls of the U-shaped positioning buckle 14, and the second screw rod 15 is arranged through the threaded holes.

[0011] Furthermore, two left-rotating shells 2 and two right-rotating shells 6 are provided.

[0012] Furthermore, the left-rotating shell 2 and the right-rotating shell 6 are staggered and their inner surfaces are arc-shaped. Specifically, the inner surfaces are surfaces that are in contact with the rotating shaft.

[0013] Furthermore, a layer of rubber pad 7 is disposed inside the left half ring 1 , and a layer of rubber pad 8 is disposed inside the right half ring 5 .

[0014] Compared with the prior art, the utility model suspension wire clamp has the following beneficial effects:

[0015] The left half ring and the right half ring are used to place the transmission line inside and constrain it. After the transmission line is placed in the middle, it is fixed and clamped using the first screw pair, and finally the transmission line is fixed to the specified position with the U-shaped positioning buckle and the second screw. The utility model has few parts and components, which effectively solves the problem that power transmission workers currently need to carry many parts and tools during high-altitude operations. The operation is simple and easy to use, which saves time and effort, improves work efficiency, and reduces the safety hazards of workers working at high altitudes. BRIEF DESCRIPTION OF THE DRAWINGS
