Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transmission tower maintenance, and in particular to a rapid reinforcement device and implementation method for single-angle steel members of transmission towers. Background Art
[0002] As a key support structure in the power transmission network, transmission towers are exposed to the natural environment all year round. As an important part, their single-angle steel members are extremely vulnerable to factors such as wind erosion, rain, and electrochemical corrosion, resulting in a decline in structural performance. Under extreme weather conditions such as strong winds and earthquakes, the single-angle steel members may deform, fracture, etc., thereby threatening the stability of the entire transmission tower and the safety of power transmission.
[0003] Currently, there are many problems with the reinforcement means for single-angle steel members of transmission towers. Although the traditional welding reinforcement method can enhance the strength of the members to a certain extent, the high temperature during the welding process is likely to change the material properties of the single-angle steel, cause thermal stress concentration, weaken the bearing capacity of the original member, and the welding quality is greatly affected by the technical level of the workers, with low construction efficiency. For the reinforcement method using ordinary hexagon socket head cap screws to connect auxiliary members, over time and under the action of the external environment, the hexagon socket head cap screws are prone to looseness, and it is difficult to maintain the reinforcement effect for a long time, and the durability of the reinforcement device is insufficient. In addition, the existing reinforcement methods generally have cumbersome construction steps, require a large amount of manpower and material resources, and cannot meet the requirements of rapid and efficient reinforcement during emergency repairs or large-scale maintenance. Therefore, it is of urgent practical significance to develop a rapid reinforcement technology for single-angle steel members of transmission towers that is efficient, convenient, and reliable. Summary of the Invention
[0004] The existing reinforcement methods for single-angle steel members of transmission towers have the following deficiencies: First, the traditional welding reinforcement method is prone to changing the material properties of the single-angle steel, causing thermal stress concentration, weakening the bearing capacity of the original member, and the welding quality is greatly affected by the technical level of the workers, with low construction efficiency; second, the ordinary bolt connection reinforcement method has poor durability, the bolts are prone to looseness, and it is difficult to maintain the reinforcement effect for a long time; third, the existing reinforcement methods have cumbersome construction steps, large investment in manpower and material resources, and cannot meet the requirements of rapid and efficient reinforcement.
[0005] The present invention aims to provide a rapid reinforcement device and implementation method for single-angle steel members of transmission towers to overcome the defects of poor reinforcement effect, complex construction, poor durability, and inability to be implemented quickly in the prior art, and achieve rapid, efficient, and reliable reinforcement of single-angle steel members, improving the operation safety and stability of transmission towers.
[0006] To achieve the above object, the technical solution adopted by the present invention is:
[0007] A rapid reinforcement device for a single-angle steel member of a transmission tower, comprising a single-angle steel, angle steel auxiliary materials, upper clamping reinforcement, lower clamping reinforcement, vulcanized rubber, bolts and spring washers. The angle steel auxiliary materials are matched with the single-angle steel by a clamping method to enhance the overall structural stability; the upper clamping reinforcement and the lower clamping reinforcement are respectively installed at the upper and lower ends of the single-angle steel member, and the two are connected by bolts and spring washers to form a stable clamping structure; the vulcanized rubber is distributed at the joints and gaps of each component, and its performance of buffering, shock absorption, sealing, corrosion resistance and increasing friction is utilized to improve the overall performance of the device.
[0008] Rubber hardness selection
[0009] In practical applications, the selection of the hardness of vulcanized rubber needs to be determined according to specific usage requirements and working conditions, and it is generally more common between 40 and 90 degrees of Shore A hardness. The following are the recommended rubber hardness ranges for the application scenarios of the present invention:
[0010] 1. Sealing purpose: At the connection parts of the reinforcement device, in order to ensure good sealing effect, the rubber hardness is usually about 60 to 80 degrees of Shore A. If the hardness is too low, the rubber is easily extruded out of the sealing gap and cannot achieve effective sealing; if the hardness is too high, it is difficult to adapt to the small deformation of the sealing surface and will also affect the sealing performance.
[0011] 2. Shock absorption and buffering purpose: When the transmission tower is impacted by wind or other external forces, the rubber needs to have good elasticity to absorb the vibration energy. At this time, the rubber hardness is generally between 40 and 60 degrees of Shore A. The lower hardness can make the rubber generate larger deformation when being vibrated, so as to effectively buffer the impact force.
[0012] 3. Durability and stability: During long-term use, the rubber needs to have a certain hardness to maintain the structural stability, and the hardness is usually about 70 to 90 degrees of Shore A. The higher hardness can reduce the deformation and improve the long-term reliability of the device.
[0013] In addition, in practical applications, factors such as the connection method between rubber and steel, the temperature, humidity, chemical medium of the working environment, etc. that affect the rubber hardness also need to be considered. For example, in a high-temperature environment, the rubber will become soft, and at this time, rubber with a higher initial hardness may need to be selected; in an environment with chemical corrosion medium, the hardness of the rubber may also change, and a suitable rubber material resistant to chemical corrosion needs to be selected and the hardness adjusted.
[0014] Implementation method
[0015] A rapid reinforcement method for a single-angle steel member of a transmission tower, comprising the following steps:
[0016] 1. Clean the surface of the single-angle steel member to thoroughly remove impurities such as oil stains and rust.
[0017] 2. Preliminarily assemble the angle steel auxiliary material and the single angle steel.
[0018] 3. Paste a layer of vulcanized rubber on the inner sides of the upper clamping reinforcement and the lower clamping reinforcement respectively, and then place them at the upper and lower ends of the single angle steel and the angle steel auxiliary material respectively.
[0019] 4. Paste the vulcanized rubber connecting piece on the outer side of the single angle steel member.
[0020] 5. Use bolts and spring washers to connect the upper clamping reinforcement, the lower clamping reinforcement with the single angle steel and the angle steel auxiliary material to construct a stable clamping structure.
[0021] 6. Tighten the bolts strictly in accordance with the requirements of the national standard.
[0022] 7. Carefully check the filling quality of the vulcanized rubber to ensure there are no voids and no missing filling.
[0023] 8. After the reinforcement is completed, comprehensively detect the overall stability of the reinforcement device and the connection status of each component.
[0024] Compared with the prior art, the advantages of the present invention are as follows:
[0025] 1. Fast construction: Adopt the snap connection and bolt connection methods, without complex welding processes, greatly shortening the construction time and meeting the requirements of emergency repair and rapid maintenance.
[0026] 2. Enhanced stability: The upper clamping reinforcement and the lower clamping reinforcement cooperate with the angle steel auxiliary material to reinforce the single angle steel from multiple directions, significantly improving the bearing capacity and structural stability of the single angle steel member.
[0027] 3. Good durability: The application of vulcanized rubber effectively prevents water and impurities from entering the gaps at the joints of the components, slows down the corrosion process, and at the same time buffers the external forces, extending the service life of the reinforcement device.
[0028] 4. Quality controllable: The specifications of each component are clear, the tightening torque of the bolts follows the national standard, and there are strict quality inspection links during the construction process to ensure the reliable and stable reinforcement quality.

The single-angle steel member is specifically set according to actual construction requirements and is not specifically limited in this application.
[0039] Preferably, the angle steel auxiliary material 2 is matched with the single-angle steel member 1 by a clamping method to enhance the overall structural stability. The upper clamping reinforcement 4 and the lower clamping reinforcement 5 are respectively installed at the upper and lower ends of the single-angle steel 1, and the two are connected by a bolt 6 and a spring washer 7 to form a stable clamping structure.

If necessary, organic solvents can be used for further cleaning.
[0043] 2. Preliminary assembly: Place the angle steel auxiliary materials on the cleaned single-angle steel member.
[0044] 3. Clip installation: Slowly place the upper clip reinforcement and the lower clip reinforcement pasted with vulcanized rubber on the upper and lower ends of the single-angle steel member and the angle steel auxiliary material assembly respectively, and adjust the position to accurately align the installation hole positions of each component. During the process, pay attention to protecting the vulcanized rubber layer from damage.
[0045] 4. Vulcanized rubber filling: Use special tools to fill the vulcanized rubber into the gaps at the joints of each component. During the filling process, ensure that the vulcanized rubber is dense, without voids or bubbles, and the surface is flat.
[0046] 5. Internal hexagon bolt connection: High-strength internal hexagon bolts sequentially pass through the installation hole positions of the upper clip reinforcement, the single-angle steel, the angle steel auxiliary material, and the lower clip reinforcement, put on the matching high-strength spring washers, and perform tightening operations according to the specified tightening torque. Tighten each internal hexagon bolt in sequence according to the diagonal order to ensure uniform force and firm connection.
[0047] 6. Quality inspection: After filling the vulcanized rubber, carefully check the filling quality. Use visual inspection, touch, etc. to check whether there are problems such as missing filling or non-dense vulcanized rubber. If problems are found, repair them in time. After completion of the strengthening, use professional testing equipment to detect the overall stability of the strengthening device, such as measuring the deformation of the component and checking the tightening state of the internal hexagon bolts, to ensure that the strengthening effect meets the design requirements.
