A power transmission tower reinforcing and protecting device

Abstract

This utility model discloses a reinforcement and protection device for power transmission towers, relating to the field of power transmission tower technology. The device includes a first protective plate and a tower column disposed on one side of the first protective plate. An installation groove is formed on one side of the first protective plate, and a pull plate is slidably connected inside the installation groove. A plug rod is fixedly connected to one side of the pull plate. During the insertion of the first and second protective plates, pulling the pull plate causes the plug rod to move, stretching the telescopic component and the telescopic spring. One end of the pull plate and the plug rod move away from the installation groove. After the first and second protective plates are inserted, releasing the handle allows the pull plate to return to its original position under the retraction of the telescopic spring, allowing the plug rod to insert into the slot. This applies a horizontal force to limit the locking block and locking groove, preventing them from loosening and separating, thus ensuring the reinforcement and protection of the tower column.

Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, specifically a power transmission tower reinforcement and protection device. Background Technology

[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial truss structures. The members are mainly composed of single equilateral angle steel or combined angle steel. The members are connected by coarse bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates and bolts. Some components, such as the tower feet, are made by welding several steel plates into a single assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation and construction are extremely convenient. Transmission line towers require foundations for fixed installation.

[0003] In the process of reinforcing or connecting steel plates for transmission line towers, holes are usually drilled in the original main material and then bolts are used for connection. However, drilling can damage the stress of the original main material, reduce its load-bearing capacity, and result in poor reinforcement effect.

[0004] To address these issues, we designed a reinforcement and protection device for power transmission towers. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement and protection device for power transmission towers to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a transmission tower reinforcement and protection device, including a first protective plate and a tower column disposed on one side of the first protective plate. An installation groove is provided on one side of the first protective plate, and a pull plate is slidably connected inside the installation groove. A plug rod is fixedly connected to one side of the pull plate. A second protective plate is snapped into one side of the first protective plate, and a slot is provided on one side of the second protective plate. The plug rod is inserted into the inside of the slot.

[0007] Furthermore, a telescopic component is fixedly installed inside the mounting groove. The telescopic end of the telescopic component is fixedly connected to the pull plate. A telescopic spring is sleeved on the outside of the telescopic component. One end of the telescopic spring is fixedly connected to the inner wall of the mounting groove, and the other end of the telescopic spring is fixedly connected to the pull plate.

[0008] Furthermore, a guide groove is provided on one side of the mounting groove, and a guide slider is fixedly connected to one side of the pull plate, with the guide slider slidably connected to the guide groove.

[0009] Furthermore, a handle is fixedly connected to one side of the pull plate. The handle is U-shaped and has an integrally formed anti-slip texture on its outer side.

[0010] Furthermore, a snap-fit ​​block is fixedly connected to one side of the first protective plate, and a snap-fit ​​groove is provided on one side of the second protective plate, with the snap-fit ​​block slidably inserted into the snap-fit ​​groove.

[0011] Furthermore, there are two pull plates, which are respectively located on both sides of the first protective plate.

[0012] Furthermore, the snap-fit ​​block is shaped like a "T", and the inner diameter of the snap-fit ​​groove is adapted to the outer diameter of the snap-fit ​​block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By pulling the pull plate during the insertion of the first protective plate and the second protective plate, the pull plate drives the insertion rod to move, and the telescopic component and telescopic spring are stretched. One end of the pull plate and the insertion rod are both away from the mounting groove. After the first protective plate and the second protective plate are inserted, the handle is released, and the pull plate is reset under the action of the telescopic spring, so that the insertion rod is inserted into the slot. This can apply a force to limit the locking block and the locking groove in the horizontal direction, preventing the locking block and the locking groove from loosening and separating, which would affect the reinforcement and protection effect of the iron tower column.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a reinforcement and protection device for power transmission towers, including a first protective plate 1 and a tower column 3 disposed on one side of the first protective plate 1. A mounting groove 4 is formed on one side of the first protective plate 1, and a pull plate 5 is slidably connected inside the mounting groove 4. A plug rod 9 is fixedly connected to one side of the pull plate 5. A second protective plate 2 is snapped onto one side of the first protective plate 1, and a slot 10 is formed on one side of the second protective plate 2, into which the plug rod 9 is inserted. A guide groove 11 is formed on one side of the mounting groove 4, and a guide slider 14 is fixedly connected to one side of the pull plate 5, the guide slider 14 being slidably connected to the guide groove 11. A handle 6 is fixedly connected to one side of the pull plate 5, the handle 6 being U-shaped, and the outer side of the handle 6 having an integrally formed anti-slip texture. Two pull plates 5 are provided, one on each side of the first protective plate 1.

[0021] In practice, workers can place the second protective plate 2 close to the tower column 3, ensuring the right-angled edge of the second protective plate 2 aligns with the tower column 3. Once the second protective plate 2 is aligned with the tower column 3, the first protective plate 1 can be held and moved downwards from above the second protective plate 2, aligning the locking blocks 7 on both sides of the first protective plate 1 with the locking slots 8 on both sides of the second protective plate 2. The locking blocks 7 should then slide within the locking slots 8. The first protective plate 1 is then moved vertically downwards until it is flush with the second protective plate 2. As the bottom of the protective plate 1 gradually slides closer to the bottom of the second protective plate 2, the handle 6 needs to be grasped and the pull plate 5 pulled so that the pull plate 5 slides inside the mounting groove 4. The pull plate 5 drives the insertion rod 9 away from the mounting groove 4. After the first protective plate 1 is successfully inserted into the second protective plate 2, the pull plate 5 drives the insertion rod 9 closer to the mounting groove 4. The insertion rod 9 is inserted into the slot 10, and the pull plate 5 is engaged with the first protective plate 1 and the second protective plate 2. This can apply a force to limit the engagement block 7 and the engagement groove 8 in the horizontal direction, preventing the engagement block 7 and the engagement groove 8 from loosening and separating, which would affect the reinforcement and protection effect on the iron tower column 3.

[0022] See Figure 1-4 An expansion joint 12 is fixedly installed inside the mounting groove 4. The expansion end of the expansion joint 12 is fixedly connected to the pull plate 5. An expansion spring 13 is sleeved on the outside of the expansion joint 12. One end of the expansion spring 13 is fixedly connected to the inner wall of the mounting groove 4, and the other end of the expansion spring 13 is fixedly connected to the pull plate 5.

[0023] In specific implementation, based on the above implementation, the pull plate 5 drives the insertion rod 9 to move, the telescopic component 12 and the telescopic spring 13 are stretched, and one end of the pull plate 5 and the insertion rod 9 are far away from the mounting groove 4. At this time, the bottom of the first protective plate 1 can be smoothly slid to be flush with the second protective plate 2. Then the handle 6 is released, and the pull plate 5 is reset under the action of the telescopic spring 13, so that the insertion rod 9 is inserted into the slot 10.

[0024] See Figure 1-4 A snap-fit ​​block 7 is fixedly connected to one side of the first protective plate 1, and a snap-fit ​​groove 8 is provided on one side of the second protective plate 2. The snap-fit ​​block 7 is slidably inserted into the inside of the snap-fit ​​groove 8. The snap-fit ​​block 7 is T-shaped, and the inner diameter of the snap-fit ​​groove 8 is adapted to the outer diameter of the snap-fit ​​block 7.

[0025] Working principle: During use, the operator can place the second protective plate 2 close to the tower column 3, ensuring the right-angle edge of the second protective plate 2 is aligned with the tower column 3. Once aligned, the operator can hold the first protective plate 1 and move it downwards from above the second protective plate 2, aligning the locking blocks 7 on both sides of the first protective plate 1 with the locking slots 8 on both sides of the second protective plate 2. The locking blocks 7 should then slide within the locking slots 8. The operator then moves the first protective plate 1 vertically downwards until it is flush with the second protective plate 2. As the bottom of the first protective plate 1 gradually slides closer to the second protective plate 2... When the bottom of the protective plate 2 is reached, the handle 6 needs to be held and the pull plate 5 pulled so that the pull plate 5 slides inside the mounting groove 4. The pull plate 5 drives the insertion rod 9 to move, and the telescopic component 12 and the telescopic spring 13 are stretched. One end of the pull plate 5 and the insertion rod 9 are both away from the mounting groove 4. At this time, the bottom of the first protective plate 1 can slide smoothly to be flush with the second protective plate 2. Then, the handle 6 is released, and the pull plate 5 is reset under the action of the telescopic spring 13, so that the insertion rod 9 is inserted into the slot 10. This can apply a force to limit the locking block 7 and the locking groove 8 in the horizontal direction, preventing the locking block 7 and the locking groove 8 from loosening and separating, which would affect the reinforcement and protection effect on the iron tower column 3.
