Description

Technical Field

[0001] The utility model belongs to the technical field of cable wind protection, and in particular relates to a cable wind protection swing device. Background Art

[0002] Cables are important conducting media in power and communication infrastructure, through which electricity and signals can be transmitted. With the rapid development of power and communication, the laying coverage of cables and wires has gradually increased, including installation in many environments such as cities, rural areas, and mountainous areas.

[0003] During the use of cables, as the use time increases, the cable shell gradually ages, resulting in a gradual decrease in its tension, and the cable gradually becomes loose and bulged. Especially when the cable is installed in a windy geographical environment, the frequency of reinforcement and repair is relatively high after the cable is loose. Once the cable is installed in a special geographical environment, such as above a mountain river, it is extremely difficult to repair.

[0004] During use, once the loose cables are affected by wind, they will swing violently, which may cause the cables to collide with each other easily and cause faults such as cable short circuit.

[0005] Therefore, in actual use, cable clamps are often installed on cables. However, after a long period of clamping, the cable clamps become loose, especially when clamping cables with large diameters. Once the wind blows, the cables will swing and easily break free from the clamps. The reason for the loosening of the cable clamps is that the special-shaped cable clamps are prone to accumulate rainwater, such as rainwater entering the installation gap of the cable clamps, while the traditional cable clamps do not have drainage structures. Under the influence of rainwater, especially acid rain, the cable clamps gradually rust and cannot clamp cables with large diameters. Under the action of wind, the cable clamps can be broken open by a slight shake of the cable. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide a cable wind-proof sway device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0008] A cable windproof swing device comprises a cable windproof hanger mechanism, wherein the cable windproof hanger mechanism comprises a hanger ring, and an annular groove is formed on the hanger ring; a plurality of pull-hanging rod assemblies are slidably connected in the annular groove;

[0009] The hanging rod assembly includes a plurality of hanging rods, and the lower ends of the hanging rods are fixedly connected with short sliding screws arranged vertically;

[0010] A plurality of arc-shaped openings connected to the annular grooves are provided on the side walls on both sides of the hanger ring, and the short sliding screw passes through the arc-shaped openings, and locking nuts are respectively threadedly connected at both ends of the short sliding screw;

[0011] A ball-clamping mechanism is fixedly connected to the top of the hanging rod, and the cable is locked in the ball-clamping mechanism. The cable is connected through the ball-clamping mechanism, and rainwater falls from the curved surface structure of the ball-clamping mechanism, thereby preventing the ball-clamping mechanism from being seriously rusted.

[0012] Preferably, the ball-locking mechanism comprises a ball-locking mechanism, and the ball-locking mechanism comprises an upper ball shell and a lower ball shell adapted to the upper ball shell; the upper ball shell and the lower ball shell are provided with arc-shaped through openings that match each other, and the cable is clamped between the arc-shaped through openings.

[0013] Preferably, the ball locking mechanism also includes a connecting screw fixedly connected to the top position of the pull rod, and the upper ball shell and the lower ball shell are slidably connected to the connecting screw; a pressing nut is threadedly connected to the connecting screw; the ball is locked by squeezing the upper ball shell onto the lower ball shell by pressing the nut.

[0014] Preferably, the hanging rod assembly further comprises a locking plate component for locking the plurality of hanging rods; the hanging rods are locked by the locking plate component.

[0015] Preferably, the locking plate component comprises arc-shaped locking plates spaced apart on both sides, and the hanging rod is limited between the arc-shaped locking plates;

[0016] The two ends of the arc-shaped locking plate are respectively slidably assembled and connected with long mounting screws, and the two ends of the long mounting screws are respectively threadedly connected with nuts.

[0017] Preferably, the cable wind-proof sway device further comprises a plurality of pull plate assemblies pulled between adjacent pull and hang rod assemblies.

[0018] Preferably, the pull plate assembly comprises a pull plate, both ends of which are respectively hung on adjacent long mounting screw rods;

[0020] Preferably, the rack ring, the pull plate and the arc-shaped locking plate are made of insulating rubber.

[0021] Preferably, a plurality of drainage holes are provided at the bottom of the lower spherical shell.

[0022] The utility model has the following beneficial effects:

[0023] 1. During the working process, slide and swing the hanging rod on the annular groove to adjust the posture and position to ensure that it is hung on the cable in the best posture. In this process, the short sliding screw slides in the arc-shaped mouth. After adjusting the position, tighten the locking nut to ensure that the hanging rod does not loosen. Through the above method, it is convenient to pull and clamp different cables together to form an integrated pulling structure, which greatly improves the wind resistance and is easy to operate. The posture of the hanging rod can be adjusted according to the position of the cable.

[0024] 2. During the working process, after separating the upper spherical shell from the connecting screw, clamp the cable on the arc-shaped through-hole of the lower spherical shell, slightly bend the cable to touch the connecting screw, and then pass through the arc-shaped through-hole on the other side. Then, slide the upper spherical shell down until the upper spherical shell is clamped on the lower spherical shell, and the cable is clamped between the arc-shaped through-holes. Randomly turn the push nut downward to lock the cable between the upper and lower spherical shells. At this time, the lower spherical shell touches the top of the pull-hanging rod. In the above way, rainwater falls on the stuck ball and falls from all around the stuck ball. There will be no residual rainwater, which will cause the stuck ball to rust, and the cable will easily break free from the stuck ball during use. At the same time, several drainage holes are opened at the bottom of the lower spherical shell. Once rainwater penetrates into the stuck ball during work, it is discharged from the drainage holes.

[0025] 3. Through the pull plate assembly, specifically including a pull plate, the two ends of which are respectively hung on adjacent long mounting screws; the pull plate is slidably assembled with the long mounting screws. By setting the pull plate, the three pull rod assemblies are pulled together, and then the whole device forms an integrated pulling structure, which greatly improves its wind resistance.

[0037] Example 1

[0038] like Figure 1-6As shown, a cable windproof swing device includes a cable windproof hanger mechanism, the cable windproof hanger mechanism includes a hanger ring 1, and an annular groove 11 is provided on the hanger ring 1; three pull-hanging rod assemblies 3 (distributed in an annular manner) are slidably connected in the annular groove 11. Each pull-hanging rod assembly 3 includes three pull-hanging rods 31, and the lower end of the pull-hanging rod 31 is fixedly connected to a short sliding screw arranged vertically; correspondingly, a plurality of arc-shaped openings 111 connected to the annular groove 11 are provided on the side walls on both sides of the hanger ring 1, and the short sliding screw 311 passes through the arc-shaped openings 111, and the two ends of the short sliding screw 311 are respectively threadedly connected with locking nuts.

[0039] During operation, the hanging rod 31 is slid and swung on the annular groove 11 to adjust the posture and position to ensure that it is hung on the cable in the best posture. In this process, the short sliding screw 311 slides in the arc-shaped opening 111. After adjusting the position, the locking nut is locked and clamped to ensure that the hanging rod 31 does not loosen. Through the above method, it is convenient to pull, hang and clamp different cables together to form an integrated pulling structure, which greatly improves the wind resistance and is easy to operate. The posture of the hanging rod 31 can be adjusted according to the position of the cable.

[0040] Example 2

[0041] like Figure 1-6 As shown, based on the structure of Example 1, this embodiment has a ball-locking mechanism fixedly connected to the top of the above-mentioned pulling and hanging rod 31, and the cable is locked in the ball-locking mechanism. The cable is connected through the ball-locking mechanism, and rainwater falls from the curved surface structure of the ball-locking mechanism, thereby preventing the ball-locking mechanism from being seriously rusted.

[0042] Specifically, the ball-catching mechanism with a spherical structure can prevent rainwater from remaining on the mechanism due to the curved structure, especially acid rain, and thus keep the mechanism rust-free.

[0043] Specifically, the ball-clamping mechanism includes a clamping ball, which includes an upper ball shell 33 and a lower ball shell 32 adapted to the upper ball shell 33 ; the upper ball shell 33 and the lower ball shell 32 are provided with arc-shaped through-holes 34 that match each other, and the cable is clamped between the arc-shaped through-holes 34 .

[0044] At the same time, the ball locking mechanism also includes a connecting screw 35 fixedly connected to the top position of the pulling rod 31, and the upper ball shell 33 and the lower ball shell 32 are slidably connected to the connecting screw 35; a pressing nut is threadedly connected to the connecting screw 35; the upper ball shell 33 is squeezed onto the lower ball shell 32 by pressing the pressing nut to lock the ball.

[0045] During operation, after the upper spherical shell 33 is separated from the connecting screw 35 , the cable is clamped on the arc-shaped through-hole 34 of the lower spherical shell 32 , the cable is slightly bent to contact the connecting screw 35 , and then passed through the arc-shaped through-hole 34 on the other side.

[0046] Then, slide the upper ball shell 33 down until it is clamped on the lower ball shell 32, and the cable is clamped between the arc-shaped through-holes 34. Randomly screw the pressing nut downward to lock the upper ball shell 33 and the lower ball shell 32 to lock the cable, and at this time, the lower ball shell 32 abuts against the top of the pull-hanging rod 31.

[0047] In the above manner, rainwater falls onto the card ball and falls from the surrounding areas of the card ball. No residual rainwater will be left to cause the card ball to rust, and the cable will easily break free from the card ball during use.

[0048] Meanwhile, a plurality of drainage holes A are provided at the bottom of the lower ball shell 32. Once rainwater penetrates into the card ball during operation, it is discharged from the drainage holes.

[0049] Example 3

[0050] like Figure 1-6 As shown, based on the structure of Example 2, the hanging rod assembly 3 of this embodiment further includes a locking plate component for locking the plurality of hanging rods 31; the hanging rods 31 are locked by the locking plate component. The hanging rods 31 are pressed and locked by the locking plate component to prevent the hanging rods 31 from loosening during the pulling of the cables, which causes the hanging rods 31 to shake due to the shaking of the cables.

[0051] Specifically, the locking plate component includes arc-shaped locking plates 2 spaced apart on both sides, and the hanging rod 31 is limited between the arc-shaped locking plates 2; the two ends of the arc-shaped locking plates 2 are respectively slidably assembled and connected with long mounting screws 21, and the two ends of the long mounting screws 21 are respectively threadedly connected with nuts.

[0052] By tightening the nuts on both sides, the arc-shaped locking plates 2 on both sides can fully clamp and lock the cables, ensuring that the hanging rod 31 does not loosen.

[0053] Example 4

[0054] like Figure 1-6 As shown, based on the structure of embodiment 3, the cable wind-proof swing device of this embodiment further includes a plurality of pull plate assemblies pulled between adjacent pull-hanging rod assemblies 3. The pull plate assembly includes a pull plate 4, and both ends of the pull plate 4 are respectively pulled and hung on adjacent long installation screws; the pull plate 4 is slidably assembled with the long installation screws.

[0055] By providing the pulling plate 4, the three pulling and hanging rod assemblies 3 can be pulled together, so that the whole device forms an integrated pulling structure, which greatly improves its wind resistance.

[0056] In actual operation, the hanger ring 1 is suspended in the gap at the center of the cable group, and the cables are hung up one by one in the above manner to form an integrated hanging wind-resistant structure.

[0057] Similar to the existing method, the material of the hanger ring 1, the pull plate 4 and the arc-shaped locking plate 2 is insulating rubber material.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
