Description

[0002] The ground wire hanging point structure refers to the components and devices used to fix the ground wire (also known as lightning arrester or OPGW composite optical cable) on the transmission line tower. These structures are designed to support the conductor and ground wire to ensure that they remain stable under various meteorological conditions and loads, while providing electrical connection or insulation. The design and selection of these hanging point structures need to be determined according to the voltage level, geographical environment, climatic conditions and specifications of the conductor and ground wire of the line to ensure the safety and stable operation of the entire transmission system. The three-butterfly multi-circuit transmission line tower adopts three butterfly wing-like beam structures, which can support multiple conductors, thereby realizing the function of multi-circuit power transmission. When installing the existing device, it is necessary to install the existing device on the installation beam of the tower through multiple bolts. This installation method has low installation efficiency and makes the workers work at high altitude for a long time.

A spring is arranged between the first limit blocks 7 and the first mounting member 1, and the spring is used to reset the adjacent first limit blocks 7. The first limit blocks 7 are limitedly matched with the adjacent first connecting rod 6. When the first limit block 7 contacts the round rod part of the adjacent first connecting rod 6, the cylindrical part of the first connecting rod 6 is stuck by the first limit block 7, so that the first connecting rod 6 cannot move to the right relative to the first mounting member 1.

A spring is arranged between the first limiting rod 14 and the first sliding plate 13, and the spring is used to reset the first limiting rod 14. The first fixed column 12 is provided with evenly distributed grooves, and the first limiting rod 14 is limitedly matched with the adjacent grooves on the first fixed column 12. When the first limiting rod 14 is inserted into the adjacent grooves on the first fixed column 12, the first sliding plate 13 cannot move to the left. Thin ropes are arranged between the six first limiting blocks 7 and the first sliding plate 13. The thin ropes penetrate the first mounting member 1, and the first sliding plate 13 drives the six first limiting blocks 7 to move through the adjacent thin ropes and releases the limitation of the two first connecting rods 6.

[0033] like Figure 2 , Figure 3 and Figure 7 As shown, a second fixed column 15 is fixedly connected to the left side of the first mounting member 1, and the second fixed column 15 is slidably connected to the second sliding plate 16. The upper side of the second sliding plate 16 is slidably connected to a second limiting rod 17 that penetrates it. A spring is arranged between the second limiting rod 17 and the second sliding plate 16, and the spring is used to reset the second limiting rod 17. The second fixed column 15 is provided with evenly distributed grooves, and the second limiting rod 17 is limitedly matched with the adjacent grooves on the second fixed column 15. When the second limiting rod 17 is inserted into the adjacent grooves on the second fixed column 15, the second sliding plate 16 cannot move to the left. Thin ropes are arranged between the six second limiting blocks 9 and the second sliding plate 16. The thin ropes penetrate the first mounting member 1, and the second fixed column 15 drives the six second limiting blocks 9 to move through the adjacent thin ropes and releases the limitation of the two second connecting rods 8.

[0034] like Figure 4As shown, the right side of the first limit block 7 and the right side of the second limit block 9 are both provided with downward inclined surfaces, the inclined surface of the first limit block 7 is squeezed and matched with the adjacent first connecting rod 6, when the first connecting rod 6 moves to the left, the first connecting rod 6 squeezes the adjacent first limit block 7, so that the first limit block 7 moves away from the first connecting rod 6, the inclined surface of the second limit block 9 is squeezed and matched with the adjacent second connecting rod 8, when the second connecting rod 8 moves to the left, the second connecting rod 8 squeezes the adjacent second limit block 9, so that the second limit block 9 moves away from the second connecting rod 8.

[0035] When using this device, align the first mounting member 1 and the second mounting member 2 with the mounting beam on the pole tower, then move the first mounting member 1 to the right and clamp it on the mounting beam, and then move the second mounting member 2 to the left, the second mounting member 2 drives the two first connecting rods 6 and the two second connecting rods 8 to move to the left, the two first connecting rods 6 and the two second connecting rods 8 are slidably connected after contacting the first mounting member 1, the first connecting rod 6 and the second connecting rod 8 are respectively in contact with the adjacent first limit block 7 and the adjacent second limit block 9 when moving, the first connecting rod 6 squeezes the adjacent first limit block 7 to move and compress the adjacent spring, the second connecting rod 8 squeezes the adjacent second limit block 9 to move and compress the adjacent spring, when the second mounting member 2 contacts the mounting beam, the first limit block 7 and the second limit block 9 are respectively reset under the action of the adjacent springs, and the first limit block 7 will move the adjacent The first connecting rod 6 is stuck, the second limit block 9 sticks the adjacent second connecting rod 8, and then the threaded rod 11 is rotated, the threaded rod 11 drives the sliding block 10 to move to the right, and when the sliding block 10 moves to the right, the liquid in the two first slide grooves 201 and the two second slide grooves 202 is drawn into the third slide groove 203, and negative pressure is formed in the first slide groove 201 and the second slide groove 202, so that the adjacent first connecting rod 6 and the adjacent second connecting rod 8 move to the right relative to the second mounting member 2, so that the first mounting member 1 and the second mounting member 2 gradually clamp the mounting beam, thereby completing the fixation of the device. When the device is fixed on the mounting beam, the first fixing member 4 and the second fixing member 5 clamp the grounding wire, and then the first fixing member 4 and the second fixing member 5 are fixed to the suspension rod 3 by bolts, and the first fixing member 4 and the second fixing member 5 fix the grounding wire.

[0036] When disassembling the device, first remove the bolts, then separate the first fixing member 4 and the second fixing member 5 from the hanging rod 3, thereby releasing the fixation of the ground wire, and then rotate the threaded rod 11 in the opposite direction, so that the threaded rod 11 drives the sliding block 10 to move to the left, and the sliding block 10 drives the two first connecting rods 6 and the two second connecting rods 8 to move to the left relative to the second mounting member 2, so that the first mounting member 1 and the second mounting member 2 release the clamping of the mounting beam, and then move the first limiting rod 14 and the second limiting rod 17 upward to separate the first limiting rod 14 from the first fixing column 12, and the second limiting rod 17 from the second fixing column 15, and then move the first sliding plate 13 and the second sliding plate 16 to the left, and the first sliding plate 13 and the second sliding plate 16 respectively pull the first limiting block 7 and the second limiting block 9 to move by the thin rope, so that the first limiting block 7 and the second limiting block 9 respectively release the limiting of the adjacent first connecting rod 6 and the adjacent second connecting rod 8, and then separate the first mounting member 1 and the second mounting member 2 and remove them from the mounting beam.

[0037] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 8 As shown, it also includes two elastic sleeves 18 distributed symmetrically on the left and right. The elastic sleeves 18 are used to fix the ground wire and avoid friction and wear between the ground wire and the first fixing member 4 and the second fixing member 5. The two elastic sleeves 18 are respectively fixed to the inner side of the first fixing member 4 and the inner side of the second fixing member 5. The first fixing member 4 and the second fixing member 5 respectively form cavities with adjacent elastic sleeves 18, and the cavities are filled with liquid. The upper side of the first fixing member 4 and the upper side of the second fixing member 5 are both slidably connected with sliding sleeves 19. The first fixing member 4 and the second fixing member 5 are respectively filled with liquid with adjacent sliding sleeves 19. The first fixing member 4 and the second fixing member 5 are both provided with channels, and the channels connect the adjacent sliding sleeves 19 with the adjacent cavities. The two sliding sleeves 19 are both squeezed and matched with bolts. When the first fixing member 4 and the second fixing member 5 are fixed by bolts, as the bolts are gradually tightened, the bolts and nuts squeeze the two sliding sleeves 19 respectively, and the two sliding sleeves 19 move toward each other.

[0038] like Figure 8 As shown, the first fixing member 4 is rotatably connected to four evenly distributed rollers 20, and the four rollers 20 are all rotated and slidably matched with the second fixing member 5. When the device is disassembled, the rollers 20 are separated from the second fixing member 5, and the middle part of the rollers 20 is recessed inward to increase the contact area with the ground wire, thereby reducing the pressure on the ground wire and avoiding deformation of the ground wire.

[0039] When the first fixing member 4 and the second fixing member 5 fix the ground wire, the first fixing member 4 drives the four rollers 20 to move to the left, and the four rollers 20 are connected to the second fixing member 5, and then the bolts are passed through the suspension rod 3, the first fixing member 4 and the second fixing member 5 and tightened. As the bolts are gradually tightened, the bolts and nuts squeeze the two sliding sleeves 19 respectively, and the two sliding sleeves 19 move toward each other and press the liquid into the adjacent cavities through the adjacent channels. The liquid in the cavity increases, causing the adjacent elastic sleeves 18 to expand and squeeze the ground wire, thereby improving the firmness of the fixation of the ground wire and avoiding the ground wire from directly contacting the first fixing member 4 and the second fixing member 5, so as to prevent the friction between the ground wire and the first fixing member 4 and the second fixing member 5 when the ground wire shakes and causes wear.

[0040] When adjusting the tension of the ground wire, loosen the bolt. As the squeezing force of the bolt on the sliding sleeve 19 decreases, the adjacent elastic sleeves 18 press the liquid in the adjacent cavity into the adjacent sliding sleeves 19 through the adjacent channels under the action of their own elasticity. At this time, the elastic sleeves 18 release the squeezing of the ground wire, and then the tension of the ground wire can be adjusted. During adjustment, the ground wire is supported by four rollers 20, thereby reducing the resistance of the ground wire when moving. When disassembling the first fixing member 4 and the second fixing member 5, remove the bolt and then separate the first fixing member 4 and the second fixing member 5.

[0041] Embodiment 3: Based on Embodiment 2, a three-butterfly type multi-circuit transmission line tower, such as Fig.10 As shown, the structure for installing the above-mentioned anti-tilt ground wire hanging point includes a pole tower, and the pole tower is provided with an anti-corrosion coating.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
