Technical Field

[0001] The utility model relates to the technical field of jumper hardware, in particular to an overhead line jumper hardware. Background Art

[0002] Jumper hardware refers to the hardware that connects and fixes the tension insulator strings, jumper insulator strings and jumpers on the tension tower. Jumper hardware includes jumper spacers, weights, support frames, aluminum tubes, pull rods, equalizing shielding rings and various special connection and fixing hardware for jumpers.

[0003] However, in the prior art, the line fittings used for fixing the lines are generally fixed structures, and the distances between cables of different overhead lines are uncertain. Jumper fittings of fixed specifications are often not applicable, which is not conducive to the fixing of cables. Therefore, we propose an overhead line jumper fitting. Utility Model Content

[0010] The beneficial effects of the utility model are:

[0011] 1. The connection between the mobile frame and the fixed frame is achieved by setting a screw rod. The distance between the mobile frame and the fixed frame can be adjusted by rotating the screw rod, which makes it easier for the device to be used in different overhead lines, making the cable fixation more convenient and more applicable. A limit rod is set for the auxiliary connection between the mobile frame and the fixed frame to prevent accidental breakage of the screw rod, which is safer.

[0012] 2. By setting the connecting rod, an installation foundation is provided for other components. The fixing rod is rotatably connected to the connecting rod, so that the fixing rod can be rotated and the direction of the fixing rod can be adjusted. It can be fixed with cables in different directions, which is more applicable.

[0020] The following is combined with Figure 1-3The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model is an overhead line jumper hardware, including a vertically arranged connecting ring 1, a plurality of connecting rods 2 are transversely fixedly installed on the outer side wall of the connecting ring 1, and the plurality of connecting rods 2 are arranged at equal intervals. A fixing rod 3 is rotatably sleeved on the outer side wall of the connecting rod 2, and auxiliary rings are slidably matched on both sides of the fixing rod 3. The auxiliary rings are fixedly sleeved on the outer side wall of the connecting rod 2, and the auxiliary rings are used to limit the fixing rod 3 to ensure that the fixing rod 3 can only rotate but not move transversely to ensure stability. A fixing frame 4 is fixedly installed on one end of the fixing rod 3 away from the connecting rod 2, and the fixing frame 4 is connected to A movable frame 5 is provided with a first half ring 6 fixedly installed transversely on the outer side wall of the movable frame 5, a second half ring 7 is rotatably installed on the upper end face of the first half ring 6, and connecting pieces 13 are fixedly installed on the outer side walls of the first half ring 6 and the second half ring 7 respectively, and the two connecting pieces 13 are fixedly connected by screws, and the first half ring 6 and the second half ring 7 are connected and fixed by screws, so as to fix the line. The device connects the movable frame 5 and the fixed frame 4 by setting a screw rod 8, and can be applied to different overhead lines. At the same time, the movable frame 5 and the fixed frame 4 are fixed with the aid of a limit rod 10, which can avoid the breakage and separation of the screw rod, and is safer and more reliable.

[0023] Example 2

[0024] like Figure 1-3 As shown, the adjustment mechanism includes a screw rod 8 which is installed on the outer wall of the fixed frame 4 for transverse rotation. The screw rod 8 thread penetrates the movable frame 5. The end of the screw rod 8 is fixedly installed on the knob 9. Rotating the screw rod 8 can control the distance between the fixed frame 4 and the movable frame 5, thereby controlling the total length thereof, which is convenient for application to different overhead lines. Limit rods 10 are respectively arranged on both sides of the screw rod 8. The two ends of the limit rod 10 respectively penetrate the movable frame 5 and the fixed frame 4. The two ends of the limit rod 10 respectively fix the limit blocks 11. The outer wall of the limit rod 10 is movably sleeved with a spring 12, which is arranged between the movable frame 5 and the fixed frame 4. The limit rod 10 cooperates to connect the fixed frame 4 and the movable frame 5 to provide safety protection. When the screw rod 8 breaks accidentally, the connection between the fixed frame 4 and the movable frame 5 can still be guaranteed. At the same time, the movable frame 5 can be limited to prevent the movable frame 5 from deflecting, thereby ensuring the stability of the device function.

[0025] Working principle:

[0026] When in use, rotating knob 9 drives screw rod 8 to rotate, adjusts the distance between fixed frame 4 and movable frame 5, and adjusts the total length from fixed rod 3 to first half ring 6, so that the device can adapt to the corresponding overhead line, and then places the cable of the line between first half ring 6 and second half ring 7, and then uses screws to fix first half ring 6 and second half ring 7 to fix the cable, repeats this operation to fix other cables with first half ring 6 and second half ring 7 to complete the installation.
