Description

Technical Field

[0001] This utility model belongs to the field of power engineering technology, specifically a power transmission tower stringing device. Background Technology

[0002] Power transmission towers (also known as transmission line towers) are tall steel structures used to support the conductors and lightning protection wires of high-voltage, ultra-high-voltage, and extra-high-voltage overhead transmission lines. They are one of the core infrastructures of the power transmission system.

[0003] The power transmission tower stringer is the core functional component of the power transmission tower. It refers to a special structural assembly used to fix and support the transmission conductors and ensure a safe distance between the conductors and the tower body, as well as between the conductors themselves. It is a key load-bearing unit for realizing power transmission.

[0004] However, in actual use, due to the weight of the conductor itself, such devices are prone to natural sag when suspended for a long time. This causes the conductor to continuously contact and rub against the inner wall of the wire hole, which not only causes wear on the outer surface of the conductor and shortens its service life, but may also affect the stability of power transmission due to the loss caused by friction. Therefore, a power tower stringing device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a power tower stringing device.

[0007] Preferably, the inner wall of the wire feeding port has two storage slots, the inner wall of the storage slots is equipped with a rotating shaft, the middle of the rotating shaft is equipped with a second rotating plate, the second rotating plate rotates in the storage slots through the rotating shaft, and a top block is fixed to the end of the second rotating plate.

[0008] Preferably, a connecting rope is fixed to the side wall of the second rotating plate, the connecting rope is slidably disposed inside the support block, and a winding block is fixed to the outer wall of the support block, the winding block having a slot in the middle.

[0009] Preferably, an elastic rope is fixed to the side wall of the support block, the other end of the elastic rope is fixed to the top of the first rotating plate, and two impact balls are fixed to the middle of the elastic rope.

[0012] The beneficial effects of this utility model are: This utility model provides a power tower stringing device that solves the problem of conductors slumping due to their own weight and wearing out due to contact with the inner wall of the wire hole during use. The elastic top of the first rotating plate maintains the suspended support state of the conductor, effectively reducing the friction loss between the conductor and the inner wall of the wire hole.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figure 1-5As shown, a power tower stringing device includes a tower 1, with two stringing plates 11 fixedly connected to the side wall of the tower 1. Two wire-passing holes 12 are provided in the middle of each stringing plate 11. The device is characterized by: a support base 13 fixedly connected to the bottom of each stringing plate 11; two connecting plates 14 fixedly connected to the bottom of the support base 13 by multiple bolts; the connecting plates 14 are inclined upwards on both sides; a first rotating plate 15 is rotatably connected to the top of each connecting plate 14; two receiving columns 16 fixedly connected to the bottom of each connecting plate 14; shock-absorbing springs 17 fixedly connected to the inner wall of each receiving column 16; the top of each shock-absorbing spring 17 is fixedly connected to the bottom of the connecting plate 14; a support block 18 fixedly connected to the end of each connecting plate 14; a wire groove 19 and a wire-laying opening 110 are provided in the middle of the support block 18; the wire groove 19 and the wire-laying opening 110 are connected. This power tower stringing device uses the tower 1 as the main support structure, with the stringing plates 11 fixedly connected to the side wall of the tower 1. First, the wire is passed through the wire hole 12 in the middle of the wire-laying plate 11. Then, the wire at the outer edge is transferred to the wire groove 19 through the wire release port 110 on the support block 18. Since the support block 18 is fixed to the end of the connecting plate 14, and the connecting plate 14 is fixed to the bottom of the support base 13 by multiple bolts, and the support base 13 is fixed to the bottom of the wire-laying plate 11, the elastic first rotating plate 15 will lift the support block 18. At the same time, the shock-absorbing spring 17 on the inner wall of the storage column 16 fixed to the bottom of the connecting plate 14 can provide buffer support. This step solves the problem of the wire falling due to its own weight and contacting the inner wall of the wire hole 12 during use. The elastic lifting of the first rotating plate 15 maintains the suspended support state of the wire, effectively reducing the friction loss between the wire and the inner wall of the wire hole 12. At the same time, the shock-absorbing spring 17, together with the upward tilt of the connecting plate 14, improves the support and buffer of the device for the wire and enhances the structural stability after the wire is laid.

[0020] like Figure 1-5As shown, the inner wall of the wire release port 110 has two receiving slots 2. A rotating shaft 21 is installed on the inner wall of the receiving slot 2. A second rotating plate 22 is installed in the middle of the rotating shaft 21. The second rotating plate 22 rotates in the receiving slot 2 via the rotating shaft 21. A top block 23 is fixed to the end of the second rotating plate 22. During the process of the wire being transferred from the wire release port 110 to the wire trough 19, the second rotating plate 22 in the receiving slot 2 of the inner wall of the wire release port 110 is installed via the rotating shaft 21. In the initial state, under the torque of the rotating shaft 21, the two second rotating plates 22 are in a horizontal state. When the wire moves into the wire trough 19, the wire first presses the top of the two second rotating plates 22, causing the second rotating plates 22 to rotate. Plate 22 rotates downwards around shaft 21 into storage groove 2. After the wire enters groove 19, the second rotating plate 22 loses pressure and unfolds and resets to a horizontal state under the torque of shaft 21. At this time, the top blocks 23 at the ends of the two second rotating plates 22 press and align with each other. This step solves the problem of wire getting stuck when entering groove 19 through wire release port 110 and the problem of wire accidentally coming out due to lack of obstruction at wire release port 110. The second rotating plate 22 controlled by the torque of shaft 21 realizes the automatic opening and closing of wire release port 110, which not only facilitates the smooth entry of wire into groove 19, but also closes wire release port 110 after the wire enters, reducing the risk of wire accidentally coming out of wire release port 110.

[0021] like Figure 1-5 As shown, a connecting rope 3 is fixed to the side wall of the second rotating plate 22. The connecting rope 3 is slidably disposed inside the support block 18. A winding block 31 is fixed to the outer wall of the support block 18. A slot 32 is provided in the middle of the winding block 31. When it is necessary to continuously pull open the two second rotating plates 22, the operator operates the connecting rope 3 fixed to the side wall of the second rotating plate 22 and hangs the connecting rope 3 at the bottom of the slot 32 in the middle of the winding block 31 fixed to the outer wall of the support block 18. At this time, the tension of the connecting rope 3 can keep the second rotating plate 22 in the unfolded state. This step solves the problem that the automatic reset of the second rotating plate 22 affects the operation efficiency when batch threading of wires or maintenance operations are performed. Through the cooperation of the connecting rope 3, the winding block 31, and the slot 32, it is convenient for the operator to perform batch threading and maintenance of wires, and improves the operation convenience of the device.

[0022] like Figure 1-5As shown, an elastic rope 4 is fixed to the side wall of the support block 18, and the other end of the elastic rope 4 is fixed to the top of the first rotating plate 15. Two impact balls 41 are fixed to the middle of the elastic rope 4. During the unfolding movement of the first rotating plate 15, the other end of the elastic rope 4 fixed to the side wall of the support block 18, which is fixed to the top of the first rotating plate 15, will extend and retract with the movement of the first rotating plate 15. Under the action of inertia, the two impact balls 41 fixed to the middle of the elastic rope 4 will impact the top of the first rotating plate 15, generating vibration. This step solves the problem that dust and debris easily accumulate on the top of the first rotating plate 15, affecting its elastic support effect. By using the inertia of the movement of the first rotating plate 15 to drive the impact balls 41 to impact, the vibration cleaning of the first rotating plate 15 is achieved. The first rotating plate 15 can be kept clean without additional tools, ensuring the stability of its elastic support performance.

[0023] like Figure 1-5 As shown, a sponge pad 5 is fixedly attached to the middle of the connecting rope 3, and a friction element is fixedly attached to the inner wall of the slot 32. When the connecting rope 3 is hung in the slot 32, the sponge pad 5 fixed to the middle of the connecting rope 3 will contact the friction element fixed to the inner wall of the slot 32. Through the contact and cooperation between the sponge pad 5 and the friction element, the friction between the connecting rope 3 and the slot 32 is increased. This step solves the problem that the connecting rope 3 is easy to loosen and fall off when it is hung in the slot 32, which causes the second rotating plate 22 to be unable to maintain a continuously unfolded state. The combination of the sponge pad 5 and the friction element further improves the stability of the connecting rope 3 in the slot 32.

[0024] like Figure 1-5 As shown, a protective pad is fixed to the top of the second rotating plate 22. When the wire is pressed against the second rotating plate 22 to unfold, the protective pad fixed to the top of the second rotating plate 22 comes into direct contact with the wire, forming a buffer protection for the wire. This step solves the problem that the surface of the wire is easily scratched and damaged by the top of the second rotating plate 22 when the wire is pressed against the second rotating plate 22.

[0025] Working principle: First, the power tower stringing device uses tower 1 as the main support structure. A stringing plate 11 is fixed to the side wall of tower 1. The conductor is first passed through the wire hole 12 in the middle of the stringing plate 11. Then, the conductor at the outer edge is transferred to the wire groove 19 through the wire release port 110 on the support block 18. Since the support block 18 is fixed to the end of the connecting plate 14, and the connecting plate 14 is fixed to the bottom of the support base 13 by multiple bolts, the support base 13 is fixed to the bottom of the stringing plate 11. At this time, the elastic first rotating plate 15 will lift the support block 18, and at the same time, the bottom of the connecting plate 14 is fixed to the support plate 11. The shock-absorbing spring 17 on the inner wall of the storage column 16 provides cushioning support. During the process of the wire being transferred from the wire outlet 110 to the wire trough 19, the second rotating plate 22 in the storage groove 2 on the inner wall of the wire outlet 110 is installed via the rotating shaft 21. In the initial state, under the torque of the rotating shaft 21, the two second rotating plates 22 are in a horizontal state. When the wire moves into the wire trough 19, the wire first presses the top of the two second rotating plates 22, causing the second rotating plates 22 to rotate downwards around the rotating shaft 21 into the storage groove 2. After the wire enters the wire trough 19, the second rotating plates 22 lose pressure, and the rotating shaft 21... Under torque, the plate unfolds and returns to a horizontal position. At this time, the top blocks 23 at the ends of the two second rotating plates 22 are pressed and aligned with each other. When it is necessary to continuously pull the two second rotating plates 22 apart, the operator operates the connecting rope 3 fixed to the side wall of the second rotating plate 22 and hangs the connecting rope 3 at the bottom of the slot 32 in the middle of the winding block 31 fixed to the outer wall of the support block 18. At this time, the tension of the connecting rope 3 can keep the second rotating plate 22 in the unfolded state. During the unfolding movement of the first rotating plate 15, the other end of the elastic rope 4 fixed to the side wall of the support block 18 is fixed to the top of the first rotating plate 15. The elastic rope 4 will expand and contract with the movement of the first rotating plate 15. Under the action of inertia, the two impact balls 41 fixed in the middle of the elastic rope 4 will impact the top of the first rotating plate 15 and generate vibration. When the connecting rope 3 is hung in the slot 32, the sponge pad 5 fixed in the middle of the connecting rope 3 will contact the friction element fixed in the inner wall of the slot 32. Through the contact and cooperation between the sponge pad 5 and the friction element, the friction between the connecting rope 3 and the slot 32 is increased. When the wire is pressed to unfold the second rotating plate 22, the protective pad fixed in the top of the second rotating plate 22 will directly contact the wire, forming a buffer protection for the wire.
