Description

Technical Field

[0001] The present invention relates to the technical field of cable suspension, and more particularly to an insulation suspension device for a cable. Background Art

[0002] A cable is a combination of conductors used to transmit power, communication signals or data. They are usually made of metal conductors (such as copper or aluminum) and wrapped in insulation materials and sheaths to protect the conductors from damage by the external environment and ensure effective transmission.

[0003] At present, when a fault occurs at a certain point in a certain section of a transmission line, but the line must continue to operate, it is necessary to implement a solution of adding a temporary line between the transmission end and the receiving end of the fault point of the original transmission line, that is, a "bypass". When the live bypass cable of the distribution network overhead line is operated, the suspension of the bypass flexible cable mainly uses hardware such as hoops to fix the bypass flexible cable on the crossarm of the circuit tower.

[0004] The cable is temporarily suspended by hardware such as hoops, and it is difficult to set the temporarily installed cables to their original slackness. The cables are suspended in the air and are easily affected by the wind and other environmental factors, causing shaking, which can easily lead to friction between the cables and hardware such as hoops, causing wear on the surface of the cables, posing a safety hazard. In addition, during the installation process, when multiple cables need to be installed, the cables are usually fixed together, which is not only inconvenient for later sorting and re-installation, but the cables bundled together are relatively less safe and not convenient to install.

[0016] Technical effects and advantages of the present invention:

[0017] 1.

[0018] 2. The present invention sets a spring telescopic rod so that two rubber limit rollers limit the two ends of the cable body.

At the same time, the cable body is supported by the rubber limit rollers to avoid the shaking of the cable body and friction with other objects, thereby preventing the cable body from being worn and increasing the service life of the cable body.

[0019] 3. The present invention places the cable body between the extrusion cards at both ends through the first connecting plate and the second connecting plate, supports and fixes the cable body by the elasticity of the extrusion cards, and presses the first connecting plate and the second connecting plate at the same time to move the card strip to one side of the second connecting plate, and by rotating the adjusting nut, the first connecting plate and the second connecting plate are brought close to and squeezed against each other to lock the cable body. The installation is simple and convenient, and there is no need to fix it by separately placing bolts and nuts. It is more suitable for installers who climb high.

[0020] 4. When the cable body is relatively loose when hanging, turn the rotating knob to rotate the rotating screw, lower the lifting block, and pull the rotating rod through the connecting rod to make the rotating rod rotate on the top of the fixed plate. The rubber pressing roller descends and presses the bottom cable body downward to bend the cable body between the fastening component and the hanging component, tighten the cable body, and then adjust the slackness of the cable body to tighten the cable body to avoid sagging due to low slackness of the cable body. At the same time, reduce the impact of natural environment such as wind on the cable body, thereby extending the service life of the cable body.

[0021] 5. The present invention supports the cable body by arranging the first rubber support roller and the second rubber support roller, so that when the cable body is bent, the second rubber support roller and the first rubber support roller buffer the transition of the cable body, thereby avoiding excessive bending of the cable body, friction between the cable body and the sliding block or the support plate, and wear of the cable body.

[0040] Third embodiment

[0041] As attached Figure 1 and 6 As an implementation of the present invention, the cable body 6 is placed between the extrusion cards 49 at both ends through the first connecting plate 42 and the second connecting plate 410.

At the same time, insulation is formed between the fastening sleeve 41 and the cable body 6 to prevent the fastening assembly 4 from generating current, thereby further improving the safety of the suspension device.

[0045] Fourth embodiment

[0046] As attached Figure 1-2 7 is an embodiment of the present invention. When the cable body 6 is relatively loose when being suspended, the rotating knob 54 is turned to rotate the rotating screw 53, the lifting block 55 descends, and the rotating rod 56 is pulled by the connecting rod 59 to rotate the rotating rod 56 on the top of the fixed plate 51. The rubber pressing roller 58 descends and presses the bottom cable body 6 downward to bend the cable body 6 between the fastening component 4 and the hanging component 3, tighten the cable body 6, and then adjust the slackness of the cable body 6 to tighten the cable body 6 to avoid the cable body 6 from sagging due to the low slackness, and at the same time reduce the impact of natural environment such as wind on the cable body 6, thereby extending the service life of the cable body 6.

[0047] As attached Figure 7 The adjusting device 5 includes two fixed plates 51, which are fixedly installed on both sides of the bottom of the sliding block 31 respectively. A lifting groove 52 is opened inside the lower end of the fixed plate 51, a rotating rod 56 is rotatably installed on the upper end of the fixed plate 51, and a rubber pressing roller 58 is rotatably installed on the top of the rotating rod 56. A rotating screw 53 is rotatably installed inside the lifting groove 52, and a rotating knob 54 is fixedly connected to the bottom of the rotating screw 53. A lifting block 55 is threadedly connected to the outer surface of the rotating screw 53, and the lifting block 55 is slidably installed inside the lifting groove 52.

[0048] The rotating rod 56 has an L-shaped shape, a fixed rod 57 is fixedly connected to the middle of the rotating rod 56 , a connecting rod 59 is rotatably mounted on the outer surface of the fixed rod 57 , and the bottom of the connecting rod 59 is rotatably mounted on one side of the lifting block 55 .

[0049] One end of the rotating rod 56 close to the rubber pressing roller 58 is movably sleeved on the outer surface of the cable body 6 , and the rubber pressing roller 58 is rotatably installed on the top of the cable body 6 .

[0050] When the rubber pressing roller 58 presses the top of the cable body 6, the first rubber supporting roller 36 and the second rubber supporting roller 311 are provided to support the cable body 6, so that when the cable body 6 is bent, the second rubber supporting roller 311 and the first rubber supporting roller 36 are used to buffer the transition of the cable body 6, so as to avoid excessive bending of the cable body 6, friction between the sliding block 31 or the supporting plate 310, and wear of the cable body 6. At the same time, the first rubber supporting roller 36 and the second rubber supporting roller 311, the rubber limiting roller 312 and the insulating rubber pad 411 are provided with insulating rubber materials, so as to insulate the contact part between the suspension device and the cable body 6, avoid current generation in the suspension device, and improve the safety of the overall device.

[0051] The working principle of the present invention is as follows: when in use, according to the position of the cable body 6, the locking bolt 33 is rotated to loosen the sliding block 31 and the support rail 24, and a plurality of sliding blocks 31 on the top of the support rail 24 are pushed to form a gap between the plurality of sliding blocks 31, and the locking bolt 33 is used to lock them, thereby adjusting the gap between the plurality of cable bodies 6, so that the suspension device can suspend the plurality of cable bodies 6, and at the same time, the plurality of cable bodies 6 are separated from each other.

[0052] When installing the cable body 6, the cable body 6 is placed between the extrusion cards 49 at both ends through the first connecting plate 42 and the second connecting plate 410. Through the elastic material of the extrusion card 49, when the cable body 6 is squeezed between the two extrusion cards 49, the extrusion card 49 clamps and fixes the cable body 6 through its own reaction, and supports the outer surface of the cable body 6 through the insulating rubber pad 411 to prevent the cable body 6 from being worn due to the clamping of the extrusion card 49. By rotating the adjusting nut 47, the first connecting plate 42 and the second connecting plate 410 are brought close to and squeezed against each other, and the clamping strip 45 is rotated so that the clamping strip 45 is clamped between the second connecting plate 410 and the positioning tube 46. By rotating the adjusting nut 47, the first connecting plate 42 and the second connecting plate 410 are locked to fix the cable body 6.

[0053] When the cable body 6 is relatively loose when suspended, the rotating knob 54 is turned to rotate the rotating screw 53, the lifting block 55 descends, and the rotating rod 56 is pulled by the connecting rod 59 to rotate the rotating rod 56 on the top of the fixed plate 51. The rubber pressing roller 58 descends and presses the bottom cable body 6 downward to bend the cable body 6 between the fastening component 4 and the suspension component 3, tighten the cable body 6, and then adjust the slackness of the cable body 6 to tighten the cable body 6, avoid the cable body 6 from being too loose and causing the cable body 6 to sag, and at the same time reduce the impact of natural environment such as wind on the cable body 6, thereby extending the service life of the cable body 6.
