Description

Technical Field

[0001] This utility model relates to the field of power facility technology, specifically to an overhead line optical cable suspension tension string. Background Technology

[0002] The suspension tension string for overhead optical cable is mainly used for fixing and supporting overhead optical cable lines, ensuring that the optical cable maintains stable tension and position under different environmental conditions. This device typically includes components such as suspension clamps and tension clamps.

[0003] In current engineering construction, when the fiber optic cable suspension tension string is connected to the tower using hardware, the height of the tension string on the tower is fixed, lacking effective adjustment methods. Because the height cannot be adjusted, the tower bears relatively large forces. As a key supporting component of the entire structure, the tower faces significant pressure and risk due to this increased stress. From an overall structural perspective, excessive stress on the tower can severely impact the stability of the entire structure, making it more vulnerable. When faced with external factors such as wind and vibration, it is more prone to swaying, deformation, or even damage, posing a serious threat to the safety and reliability of the entire project. Utility Model Content

[0004] The purpose of this invention is to provide an overhead line optical cable suspension tension string, which aims to solve the problem that the height of the optical cable suspension tension string is inconvenient to adjust in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the overhead line optical cable suspension tension string includes a triangular plate for installation on the tower column and tension clamps connected to the left and right sides of the triangular plate respectively.

[0006] Optical cables are wound around the opposite sides of the two tension clamps, and a parallel groove clamp is connected between the two optical cables to enable signal communication between the two optical cables.

[0007] The tower column is equipped with a lifting assembly, and the triangular plate is mounted on the lifting assembly, which enables the triangular plate to move up and down.

[0008] Preferably, the lifting assembly includes an upper retaining ring fixed above the tower column, a lower retaining ring fixed below the tower column, and a threaded rod rotatably disposed between the upper and lower retaining rings and extending vertically.

[0009] Preferably, the triangular plate has a threaded hole that is open at both ends for inserting the threaded rod, and the triangular plate is threadedly connected to the threaded rod;

[0010] The triangular plate has two through holes, one above the other. A light rod is rotatably mounted between the upper and lower retaining rings and is inserted into the through holes on the triangular plate.

[0011] Preferably, a second knob is fixedly connected to the threaded rod by an upper retaining ring.

[0012] Preferably, several sets of adjusting components are connected to the left and right sides of the triangular plate, and adjacent sets of adjusting components are connected by bolts.

[0013] Preferably, the adjusting member has a cross-shaped structure, which includes a long connecting section and a short connecting section, and the long connecting section and the short connecting section are arranged perpendicularly to each other.

[0014] Preferably, the side of the adjusting member away from the triangular plate is connected to a triangular connecting plate, and each triangular connecting plate is connected to a heart-shaped ring near the corner. The two heart-shaped rings on the same side are connected to the same tension clamp.

[0015] Preferably, the long connecting section includes a long plug section and a long sleeve section;

[0016] The triangular plate has sockets on its left and right sides for inserting the long plug section. The long plug section has a through first bolt hole, and the socket has a through second bolt hole.

[0017] The triangular connecting plate is fixedly connected to a connector inserted into the long sleeve section at one end facing the adjusting component. The long sleeve section has a through third bolt hole, and the connector has a through fourth bolt hole.

[0018] Preferably, the short connecting section includes a short plug section and a short sleeve section, the short plug section having a through fifth bolt hole and the short sleeve section having a through sixth bolt hole.

[0019] The beneficial effects are: 1. Rotating the second knob allows the threaded rod to rotate, causing the triangular plate to move up and down along the smooth rod under the operation of the threaded rod, thereby adjusting the position of the triangular plate on the tower column. By adjusting the position of the triangular plate, the stress distribution of the tower column can be optimized, thereby improving the stability of the entire structure.

[0020] 2. By connecting the triangular plate and the triangular connecting plate with the long or short connecting section on the adjusting component, the distance between the triangular plate and the triangular connecting plate can be adjusted. By adjusting the connecting part of the adjusting component, the sag of the optical cable can be quickly changed to adapt to different operational needs, thereby improving operational flexibility and adaptability. It can also avoid damage caused by structural deformation or stress concentration, extend the service life of the structure, and prevent structural damage. Attached Figure Description

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, an overhead line optical cable suspension tension string is mainly used to connect the optical cable 4 to the tower column 1. The optical cable suspension tension string includes a triangular plate 2 for installation on the tower column 1 and tension clamps 3 that are connected to the left and right sides of the triangular plate 2. The tension clamps 3 are connected to the triangular plate 2. The triangular plate 2 is set on the tower column 1 so that the tension clamps 3 are connected to the tower column 1.

[0028] like Figure 1 As shown, optical cables 4 are wound around the opposite sides of the two tension clamps 3. In this embodiment, the mechanism and principle of the tension clamps 3 are existing technologies and will not be described in detail here. A parallel groove clamp 5 is connected between the two optical cables 4. The parallel groove clamp 5 realizes the signal connection between the two optical cables 4. In this embodiment, the mechanism and principle of the parallel groove clamp are existing technologies and will not be described in detail here.

[0029] like Figure 1 As shown, a lifting assembly 12 is provided on the tower column 1, and a triangular plate 2 is set on the lifting assembly 12. The lifting assembly 12 can move the triangular plate 2 up and down to adjust the position of the triangular plate 2 on the tower column 1. By adjusting the position of the triangular plate 2, the stress distribution of the tower column 1 can be optimized, thereby improving the stability of the entire structure. Moreover, a reasonable position of the triangular plate 2 can reduce the deformation of the tower column 1 under load, thereby improving the performance and service life of the tower column 1.

[0030] Specifically, the lifting assembly 12 includes an upper retaining ring 1201 fixed above the tower column 1, a lower retaining ring 1202 fixed below the tower column 1, and a threaded rod 1203 rotatably disposed between the upper retaining ring 1201 and the lower retaining ring 1202 and extending vertically.

[0031] The triangular plate 2 has a threaded hole that allows the threaded rod 1203 to be inserted and is open at both ends. The triangular plate 2 and the threaded rod 1203 are threadedly matched. The triangular plate 2 has two through holes that are open at both ends. A smooth rod 19 is rotatably connected between the upper retaining ring 1201 and the lower retaining ring 1202. The smooth rod 19 is inserted into the through hole on the triangular plate 2. The setting of the smooth rod 19 prevents the triangular plate 2 from rotating, allowing it to move up and down. When the threaded rod 1203 rotates, it can drive the triangular plate 2 to move up and down along the smooth rod 19.

[0032] A second knob 13 is fixedly connected to an upper retaining ring 1201 extending from the top of the threaded rod 1203. Rotating the second knob 13 causes the threaded rod 1203 to rotate.

[0033] like Figure 3 As shown, several sets of adjusting parts 14 are connected to the left and right sides of the triangle plate 2, and adjacent sets of adjusting parts 14 are connected by bolts. Several sets of adjusting parts 14 are set according to the distance between the triangle plate 2 and the triangle connecting plate 15, and adjacent adjusting parts 14 can be detachably connected.

[0034] The side of the adjusting component 14 away from the triangle plate 2 is connected to a triangle connecting plate 15. Each triangle connecting plate 15 is connected to a heart-shaped ring 16 near the corner. The heart-shaped ring 16 is a pad used when winding the strand. The two heart-shaped rings 16 on the same side are connected to the same tension clamp 3.

[0035] like Figure 3 As shown, the adjusting component 14 has a cross-shaped structure, which includes a long connecting section and a short connecting section, and the long connecting section and the short connecting section are arranged perpendicularly to each other.

[0036] The long connecting section includes a long plug part 7 and a long sleeve part 8; the left and right sides of the triangular plate 2 are provided with sockets for the long plug part 7 to be inserted, the long plug part 7 is provided with a through first bolt hole 6, and the socket is provided with a through second bolt hole; the end of the triangular connecting plate 15 facing the adjusting member 14 is fixedly connected to a plug-in member inserted into the long sleeve part 8, the long sleeve part 8 is provided with a through third bolt hole 9, and the plug-in member is provided with a through fourth bolt hole.

[0037] In this embodiment, when the long plug part 7 is inserted into the socket on the triangular plate 2, the first bolt hole 6 and the second bolt hole correspond to each other, so that the third bolt passes through the first bolt hole 6 and the second bolt hole. When the long sleeve part 8 is inserted into the triangular connecting plate 15, the third bolt hole 9 and the fourth bolt hole correspond to each other. Then, the fourth bolt passes through the third bolt hole 9 and the fourth bolt hole to connect the triangular plate 2 and the triangular connecting plate 15.

[0038] The short connecting section includes a short plug part 10 and a short sleeve part 11. The short plug part 10 has a through fifth bolt hole 17, and the short sleeve part 11 has a through sixth bolt hole 18.

[0039] In this embodiment, when the short plug part 10 is inserted into the socket on the triangular plate 2, the fifth bolt hole 17 corresponds to the second bolt hole, so that the third bolt passes through the fifth bolt hole 17 and the second bolt hole. When the short sleeve part 11 is inserted into the triangular connecting plate 15, the sixth bolt hole 18 corresponds to the fourth bolt hole, and then the fourth bolt passes through the sixth bolt hole 18 and the fourth bolt hole to connect the triangular plate 2 and the triangular connecting plate 15.

[0040] The triangular plate 2 has an arc-shaped groove on the side facing the tower column 1 that abuts against the outer surface of the tower column 1, and two smooth rods 19 are respectively set on the left and right sides of the arc-shaped groove.

[0041] Working principle: According to the construction requirements, adjust the height of triangle 2, rotate the second knob 13 so that the second knob 13 can drive the threaded rod 1203 to rotate. When the threaded rod 1203 rotates, it can drive triangle 2 to move up and down along the smooth rod 19 to adjust the height of triangle 2, optimize the stress distribution of the tower column 1, and thus improve the stability of the entire structure. According to the distance between triangle 2 and triangle connecting plate 15, use the long connecting section or short connecting section of adjusting part 14 to connect triangle 2 and triangle connecting plate 15. When using the long connecting section... When connecting, the long plug part 7 is inserted into the socket on the triangle plate 2, and the long sleeve part 8 is inserted into the triangle connecting plate 15. Then, the triangle plate 2, the adjusting part 14 and the triangle connecting plate 15 are connected by the third and fourth bolts to achieve a long-distance connection. When using the short connecting section, the short plug part 10 is inserted into the socket on the triangle plate 2, and the short sleeve part 11 is inserted into the triangle connecting plate 15. Then, the triangle plate 2, the adjusting part 14 and the triangle connecting plate 15 are connected by the third and fourth bolts to achieve a short-distance connection, thus achieving adjustment flexibility.
