AI Technical Summary
Existing cable flutter devices cannot adjust the distance, cannot adapt to cables with different spacing, and cannot effectively counteract the swaying of the support frame caused by lateral wind forces.
An anti-flying device was designed, which includes a support frame and a sliding sleeve. The sliding sleeve is movable to accommodate cables with different spacings and is fixed by a double-ended screw. The connecting rod prevents it from falling and the lateral wind force is counteracted by a universal ball joint and a counterweight.
It effectively secures cables with varying spacing, reduces swaying, and counteracts the swaying of the support frame caused by lateral winds, protecting the cables from damage.

Description
TECHNICAL FIELD
[0001] The utility model relates to the field of cable dancer, concretely relates to an overhead power transmission cable dancer. BACKGROUND
[0002] The conductor can dance under the action of wind force, the energy of conductor dancing is very big, and the conductor dancing can wind the cable together, so the dancer is needed to support the cable and slow down the dancing, the existing cable dancer is also more, like dancer spacer, can fix multiple cables, thereby slow down the dancing of cable, but cannot adjust the distance, and cannot adapt to different spacing cable. SUMMARY
[0003] The utility model provides an overhead power transmission cable dancer.
[0004] The utility model discloses a technical scheme is like this: an overhead power transmission cable dancer, including support frame, the outside of support frame is slidably provided with several groups of movable fixed device that can fix cable, and the fixed device includes two sliding sleeves, and the sliding sleeve is slidably arranged on the support frame, and the cable is clamped between two sliding sleeves, and the middle position of the front of support frame is provided with the through -hole one of strip structure, and the sliding sleeve is provided with the through -hole two, and the through -hole one and the through -hole two are provided with the double -end screw rod in, and the both ends of double -end screw rod are connected with the nut one.
[0005] The upper portion of two sliding sleeves is provided with the connecting rod, and the connecting rod is horizontally arranged, and the connecting rod is perpendicular to the cable, and the both ends of connecting rod are connected with the nut two.
[0006] Two sides of two sliding sleeves are provided with the recess that accommodates cable.
[0007] The inner side of recess is connected with rubber layer.
[0008] The bottom of support frame is symmetrically installed with the connecting seat on both sides, and the bottom of connecting seat is installed with universal ball head, and the bottom of universal ball head is installed with heavy hammer.
[0009] The utility model discloses a technical scheme has the following positive effect: the support frame of the utility model is slidably provided with several groups of fixed device, and each fixed device includes two sliding sleeves, and the cable is clamped between two sliding sleeves and fixed, and the upper portion of two sliding sleeves is provided with the connecting rod, and the connecting rod fixes two sliding sleeves, and can prevent the whole device from falling; the sliding sleeve can move left and right on the support frame, thereby adapting to different spacing cable; the double -end screw rod fixes the sliding sleeve on the support frame; the heavy hammer can swing, thereby offsetting the swing effect of horizontal wind force on the support frame.

[0013] As Figs. 1-3 shown in the figure, an overhead power transmission cable anti-dancing device comprises a support frame 1, the outside of the support frame 1 is slidably provided with a plurality of groups of movable cable fixing devices, the fixing device comprises two sliding sleeves 2, the sliding sleeves 2 are slidably arranged on the support frame 1, a cable 3 is clamped between the two sliding sleeves 2, a horizontal through hole one 4 in strip structure is formed in the middle position of the front part of the support frame 1, a horizontal through hole two 5 is formed in the sliding sleeve 2, a double-end screw rod 6 is arranged in the through hole one 4 and the through hole two 5, and nuts one 7 are threadedly connected to the two ends of the double-end screw rod 6; specifically, the device is provided with a plurality of groups of fixing devices, a plurality of cables can be fixed at the same time, the distance between the two sliding sleeves 2 can be adjusted, a through hole 16 matched with the support frame 1 is formed in the side part of the sliding sleeve 2, so that the sliding sleeve 2 is arranged on the support frame 1 and can move, the cable 3 is clamped between the two sliding sleeves 2, then the double-end screw rod 6 is arranged through the through hole one 4 and the through hole two 5, the nuts one 7 are screwed on the two ends of the double-end screw rod 6, the sliding sleeve 2 is fixed on the support frame 1, and the sliding of the sliding sleeve 2 on the support frame 1 is prevented; after each cable is fixed, the dancing of the cable can be slowed down.
[0014] A connecting rod 8 is arranged above the two sliding sleeves 2, the connecting rod 8 is arranged through a through hole three 12, the connecting rod 8 is horizontally arranged, the connecting rod 8 is perpendicular to the cable 3, and nuts two 9 are threadedly connected to the two ends of the connecting rod 8; specifically, in order to prevent the device from falling, the connecting rod 8 is arranged between the two sliding sleeves 2, the connecting rod 8 is in contact with the cable 3, the cable 3 supports the connecting rod 8, and thus falling is prevented.
[0015] Grooves 10 for accommodating cables are formed in the two opposite side surfaces of the two sliding sleeves 2; the cable 3 is just accommodated in the groove 10, and the longitudinal section of the groove 10 is in arc structure.
[0016] A rubber layer 11 is connected to the inner side surface of the groove 10; specifically, the rubber layer 11 is in contact with the cable 3, the rubber layer is soft, and thus damage to the cable 3 is reduced.
[0017] Connecting seats 13 are symmetrically installed on the two sides of the bottom of the support frame 1, universal ball heads 14 are installed at the bottom of the connecting seats 13, and heavy hammers 15 are installed at the bottom of the universal ball heads 14; specifically, the heavy hammers 15 swing under the action of the universal ball heads 14, and thus the swinging effect of the support frame 1 caused by the transverse wind force is offset.
