Description

Technical Field

[0001] The invention relates to the technical field of cable erection, in particular to a cable support and hoist for overhead line operations on power towers. Background Art

[0002] When transmitting electricity over long distances, cables are often installed on utility poles or cable supports. To prevent cable tension from affecting their lifespan and transmission efficiency, the cables are generally allowed to extend naturally. The cables between two adjacent cable supports are suspended due to gravity. In windy weather, the suspended cables shake significantly, and the cables bend at obvious angles during the shaking process. Frequent bending can cause rapid wear. The Chinese patent announcement number is: CN116544868A discloses "An overhead cable support and suspension device". In this patent, the cable causes the traction component to move away from the center frame under the action of wind, so that the distance between the two traction components on both sides of the center frame increases, and the length of the cable supported between the two traction components increases, which can not only increase the stability of the cable support, but also reduce the suspension degree of the cable between the two adjacent overhead cable support and suspension devices, and reduce the swing amplitude of the cable. The two pressure rods approach the center frame as the two traction components move away from each other, increasing the degree of downward pressure on the cable, prompting the cable to be tightened to the support and suspension device, and further reducing the swing amplitude of the cable. The greater the displacement of the traction component, the greater the downward pressure of the pressure rod on the cable, and the greater the restrictive effect on the cable.

[0003] Existing cable support cranes for overhead power tower line operations have structural design defects. Under long-term overhead operation, the protective layer of the cable near the connection position is prone to fatigue damage, and the effect of reducing cable shaking damage by extension is poor.

[0021] The present invention provides a cable support and hoist for overhead line operations on power towers. It has the following beneficial effects:

[0022] 1. The cable support and hoist for overhead line operations on power towers uses a clamping assembly to clamp the surface of the cable body, and a buffer assembly is arranged between the top plate and the clamping assembly. When the cable body is blown by wind, the elastic support of the buffer assembly reduces the degree of shaking. At the same time, the extension limit of the clamping assembly uses line connection instead of point connection to effectively reduce the degree of squeezing between the cable body and the support and hoisting position, solving the problem that the protective layer of the cable near the connection position is prone to fatigue damage under long-term overhead operation.

[0023] 2. This cable support and hoist for overhead power tower line operations, when the external force pulling on the cable body is removed, the second spring releases the pressure so that the clamping block can quickly clamp the cable body. The circular ring structure of the limiter is used to fix and support multiple second springs. The opposing plate structure of the limiter ensures a firm connection between the circular ring and the fixed platform. The inner ring is sleeved on the outer surface of the conical shell. When the cable body is blown by wind, the first spring elastically supports the conical shell, and the power is converted into elastic potential energy, which effectively reduces the degree of shaking of the cable body.

[0024] 3. The cable support crane for overhead line operations on power towers has a tapered hole on the inner side of the sphere. External force is applied to embed the tapered surface of the half-block into the inside of the tapered hole. The half-block is made of rubber. The interference fit of the half-block enables the outer surface of the cable body to be tightly engaged with the inner side of the sphere. The half-block is fixedly connected to the sphere by through bolts, and the inner spherical ring provides rotational support for the sphere, thereby enabling the cable body to be rotationally connected to the pressing plate, and the cable body is not easily worn when shaking.

[0025] 4. The cable support and crane for overhead line operations on power towers has a slotted structure that allows the pull rope to be perforated at the bottom of the slotted tube to form multiple extension loops. During installation, the cable body passes through the multiple extension loops in sequence, and the slotted tube supports the pull rope. Subsequently, the adjustment component reels the pull rope, increasing the tension of the pull rope. The pull rope is firmly sheathed on the outer surface of the cable body, making it difficult for the cable body to fall while effectively reducing shaking, thus solving the problem of poor effect in reducing cable shaking damage by extension.

[0026] 5. The cable support and hoist for overhead line operations on power towers has a plate body that supports and limits the anti-rotation bolts. The diameter of the extension ring is reduced, so that the cable body is pulled close to the surface of the slotted tube. Subsequently, the anti-rotation bolts are screwed into the inner side of the reel to stop the reel from rotating. When the cable body is blown by wind, the conical shell vibrates along with the cable body. The elastic absorption and release of the first spring reduces the degree of shaking of the cable body. At the same time, the support of the pull rope and the slotted tube makes the cable body less likely to be damaged by shaking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] First embodiment: Figure 1-Figure 4 As shown, the present invention provides a technical solution: a cable support and hoist for overhead line operation on a power tower, comprising a support pole 1, a support platform 2 fixedly connected to the top of the support pole 1, a support plate 3 fixedly connected to the bottom of the inner side of the support platform 2, a top plate 4 fixedly connected to the top of the support plate 3, a protective platform 5 fixedly connected to the top of the top plate 4, and further comprising:

[0040] Buffer assembly 6, the buffer assembly 6 is fixedly installed at a position near the edge of the bottom of the top plate 4;

[0041] The anti-pressure loss mechanism 7 is fixedly mounted on the inner side of the buffer assembly 6. The middle part of the surface of the anti-pressure loss mechanism 7 is fixedly mounted on the top of the support platform 2. The buffer assembly 6 is used for fixed support and buffering vibration reduction of the anti-pressure loss mechanism 7. The anti-pressure loss mechanism 7 is used for supporting and protecting the cable;

[0042] The anti-sway mechanism 8 is fixedly installed in the middle of the surface of the top plate 4. The surface of the anti-sway mechanism 8 extends along the cable axis. The anti-sway mechanism 8 is used for gravity support when the cable is suspended and for stable pulling when the cable is swaying.

[0043] The anti-pressure loss mechanism 7 includes a bending plate 71 and a clamping assembly 75. The bending plate 71 is fixedly mounted on the top of the support platform 2. The top of the bending plate 71 is fixedly connected to a pressing plate 72. The surface of the pressing plate 72 is fixedly connected to a rotating assembly 73. The inner side of the rotating assembly 73 is fixedly connected to a cable body 74. The clamping assembly 75 is fixedly mounted on the inner side of the buffer assembly 6.

[0044] The rotating assembly 73 is used for limiting support of the cable body 74 , and the clamping assembly 75 is used for clamping the surface of the cable body 74 close to the rotating assembly 73 . There are multiple rotating assemblies 73 .

[0045] When in use, in the cable support structure, the cable is usually fixed to the top of the bracket by a point, and the cable is bent downward by gravity. When shaken by wind, the protective layer at the connection position is easily damaged. In this device, the cable surface is rotatably mounted on the surface of the pressing plate 72 by a rotating component 73, and the cable and the rotating component 73 are fixedly connected. The pressing plate 72 is used to determine the support point of the cable. At a position near the support point, the device uses oppositely arranged clamping components 75 to support the surface of the cable body 74. The clamping component 75 clamps the surface of the cable body 74, and the buffer component 6 is arranged between the top plate 4 and the clamping component 75. When the cable body 74 is blown by wind, the elastic support of the buffer component 6 reduces the degree of shaking. At the same time, the extension limit of the clamping component 75 uses a line connection instead of a point connection to effectively reduce the degree of extrusion between the cable body 74 and the support position, thereby solving the problem that the protective layer of the cable near the connection position is prone to fatigue damage under long-term overhead action.

[0046] Second embodiment: Figure 7 、 Figure 8 As shown, the conical shell 751 is fixedly mounted on the inner side surface of the inner ring 64. The inner side surface of the conical shell 751 is provided with an internal threaded hole 752. A disk body 753 is fixedly connected to the inner side surface of the conical shell 751. A second spring 754 is fixedly connected to the surface of the disk body 753. A sliding disk 755 is fixedly connected to the end of the second spring 754 away from the disk body 753. The clamping assembly 75 also includes a clamping block 756. The clamping block 756 is slidably mounted on the inner side surface of the conical shell 751. A threaded block 757 is connected to the position of the conical shell 751 near the internal threaded hole 752.

[0047] The buffer assembly 6 includes a fixed platform 61, which is fixedly mounted on the bottom of the top plate 4. The bottom of the fixed platform 61 is fixedly connected to a limiter 62, which is a structure formed by welding a circular ring and a plate.

[0048] The buffer assembly 6 further includes a first spring 63 , which is fixedly mounted on the inner side of the limiting body 62 , and an end surface of the first spring 63 away from the limiting body 62 is fixedly connected to an inner ring 64 .

[0049] When in use, the cable body 74 is pulled by external force to pass through the clamping block 756. The four clamping blocks 756 are combined into a conical structure. The inner side of the conical structure is provided with a through-hole structure. The through-hole structure enables the cable body 74 to pass through the clamping block 756. When the cable body 74 is forced to pass through the clamping block 756, the through-hole structure hinders the cable body 74, and the sliding plate 755 is pushed by the cable body 74 to approach the plate body 753. The cable body 74 passes through the plate body 753 and the threaded block 757 in turn. The second spring 754 is pushed and compressed. When the cable body 74 is withdrawn, When the external force is removed, the second spring 754 releases the pressure so that the clamping block 756 can quickly clamp the cable body 74. The circular ring structure of the limiting body 62 is used to fix and support multiple second springs 754. The opposing plate structure of the limiting body 62 makes the circular ring and the fixed platform 61 firmly connected. The inner ring 64 is sleeved on the outer surface of the conical shell 751. When the cable body 74 is blown by the wind, the first spring 63 elastically supports the conical shell 751, and the power is converted into elastic potential energy, which effectively reduces the shaking of the cable body 74.

[0050] The third embodiment: Figure 5-Figure 8 As shown, the rotating assembly 73 includes an inner spherical ring 731, which is fixedly mounted on the inner side of the pressing plate 72. The inner side of the inner spherical ring 731 is rotatably connected to the ball 732. The rotating assembly 73 also includes a half-block 733. The surface of the half-block 733 is fixedly connected to the extension plate 734. The inner side of the half-block 733 is threadedly connected to a through bolt 735. The surface of the half-block 733 is in close contact with the inner side of the ball 732.

[0051] The clamping assembly 75 includes a conical shell 751, which is fixedly mounted on the inner side surface of the inner ring 64. An internal threaded hole 752 is provided on the inner side surface of the conical shell 751. The inner side surface of the conical shell 751 is fixedly connected to a disk body 753. The surface of the disk body 753 is fixedly connected to a second spring 754. The end of the second spring 754 away from the disk body 753 is fixedly connected to a sliding disk 755. The clamping assembly 75 also includes a clamping block 756, which is slidably mounted on the inner side surface of the conical shell 751. A threaded block 757 is connected to the position of the conical shell 751 near the internal threaded hole 752.

[0052] When in use, the cable body 74 passes through the conical shell 751, the spherical body 732 and the conical shell 751 in sequence. When the external force on the cable body 74 is removed, the second spring 754 releases the elastic potential energy so that the sliding disk 755 is pushed away from the disk body 753, the outer surface of the threaded block 757 engages with the internal threaded hole 752, and the conical outer surface of the clamping block 756 is tightly attached to the inner side of the conical shell 751, so that the cable body 74 is quickly clamped. Subsequently, the two half-blocks 733 are fitted together and sleeved on the outer surface of the cable body 74. The half-blocks 733 after fitting together form Conical surface, a conical hole is opened on the inner side of the sphere 732, and external force is applied to make the conical surface of the half plug 733 embedded in the inside of the conical hole. The half plug 733 is made of rubber. The interference fit of the half plug 733 makes the outer surface of the cable body 74 tightly engaged with the inner side of the sphere 732. The half plug 733 is fixedly connected to the sphere 732 by a through bolt 735, and the inner spherical ring 731 provides rotational support for the sphere 732, so that the cable body 74 and the pressing plate 72 are rotatably connected, and the cable body 74 is not easily worn when shaking.

[0054] The rotating assembly 73 is used for limiting the support of the cable body 74, and the clamping assembly 75 is used for clamping the surface of the cable body 74 close to the rotating assembly 73. There are multiple rotating assemblies 73.

[0055] The anti-sway mechanism 8 includes a connecting rod 81, which is fixedly installed in the middle position of the surface of the top plate 4. The surface of the connecting rod 81 is fixedly connected to an adjustment component 82. The anti-sway mechanism 8 also includes a slotted tube 83. The top of the slotted tube 83 is provided with a through slot, the bottom of the slotted tube 83 is provided with a hole, the inner side surface of the slotted tube 83 is provided with a pull rope 84, and the surface of the pull rope 84 is provided with an extension ring 85.

[0056] When in use, in the prior art, when the cable body 74 shakes, the cable body 74 is extended and supported near the fixed connection point, thereby reducing the degree of shaking of the cable body 74. However, in actual use, due to the long length of the cable body 74, the extension structure plays a smaller role, and the cable body 74 and the fixed position are still easily squeezed and worn by each other. In this device, the adjustment component 82 supports the slotted tube 83, and the bottom of the slotted tube 83 is provided with a plurality of circular holes for the insertion of the pull rope 84. The slotted structure enables the pull rope 84 to be perforated at the bottom of the slotted tube 83 to form a plurality of extension loops 85. During installation, the cable body 74 passes through the plurality of extension loops 85 in sequence, and the slotted tube 83 supports the pull rope 84. Subsequently, the adjustment component 82 reels the pull rope 84, and the tension of the pull rope 84 increases. The pull rope 84 is firmly sleeved on the outer surface of the cable body 74. The pull rope 84 makes the cable body 74 not easy to fall and effectively reduces shaking, thereby solving the problem of poor effect of reducing cable shaking damage by extension.

[0057] Fifth embodiment: Figure 7 、 Figure 10 As shown, the fixing platform 61 is fixedly installed on the bottom of the top plate 4, and the bottom of the fixing platform 61 is fixedly connected to the limiting body 62, which is a structure formed by welding a circular ring and a plate;

[0058] The buffer assembly 6 further includes a first spring 63, which is fixedly mounted on the inner side of the limiting body 62, and an end surface of the first spring 63 away from the limiting body 62 is fixedly connected to an inner ring 64;

[0059] The adjusting component 82 includes a connecting plate 821, the inner side surface of the connecting plate 821 is fixedly mounted on the surface of the connecting rod 81, and the inner side surface of the connecting plate 821 is rotatably connected to the winding roller 823. The adjusting component 82 also includes a motor 822, which is fixedly mounted on the outer surface of the connecting plate 821, and the surface of the winding roller 823 is fixedly connected to the end face of the pull rope 84. The inner side surface of the connecting plate 821 is fixedly connected to the plate body 824, and the inner side surface of the plate body 824 is threadedly connected to a stop bolt 825.

[0060] When in use, the slotted tube 83 is made of a plastic-dipped metal tube. The rigidity of the slotted tube 83 makes the pull rope 84 more stable when it is inserted. Compared with using only the pull rope 84 for pulling, the flexibility of the pull rope 84 will make the cable body 74 support effect poor. At the same time, the pull rope 84 is easy to shake when blown by the wind. The bottom of the connecting plate 821 is provided with a cavity, and the winding roller 823 is arranged inside the cavity. The motor 822 drives the winding roller 823 to rotate so that the pull rope 84 is wound. The slotted tube 83 rigidly supports the pull rope 84, and the plate body 82 The anti-rotation bolts 825 are supported and limited, and the diameter of the extension ring 85 is reduced, so that the cable body 74 is pulled close to the surface of the slotted tube 83. Subsequently, the anti-rotation bolts 825 are screwed into the inner side of the winding roller 823, so that the winding roller 823 is stopped from rotating. When the cable body 74 is blown by wind, the conical shell 751 vibrates with the cable body 74. The elastic absorption and release of the first spring 63 reduces the shaking of the cable body 74. At the same time, the support of the pull rope 84 and the slotted tube 83 makes the cable body 74 less likely to be damaged by shaking.
