Description
Technical Field
[0001] This utility model relates to the field of conductor tension string technology, and in particular to a conductor tension string structure that is easy to install. Background Technology
[0002] Tension insulator strings are crucial components in power transmission lines, primarily used to withstand the tension of conductors and maintain their stability during transmission. They consist of tension insulators, conductors, and connecting hardware, and are installed in the middle of the tower to ensure the conductor's horizontal position remains constant. Tension insulator strings are the most common product used in modern power transmission line installations, used in conjunction with power fittings. Several strings are strung together to achieve the required tension, depending on the construction needs. In short, an insulator string is a combination of two or more insulators, flexibly suspending the overhead conductor. The insulator string primarily bears tension.
[0003] An existing type of easy-to-install conductor tension string structure can be inefficient when workers are using the equipment in conjunction with the overall system, as the operation steps are often cumbersome and this can affect the efficiency of easily installing the equipment in the appropriate location. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a conductor tension string structure that is easy to install.
[0005] This utility model is achieved by the following technical solution: a conductor tension string structure that is easy to install, including a mounting plate, a connecting ring fixedly connected to the top of the mounting plate, a vertical plate fixedly connected to the right end of the mounting plate, a locking screw connected to the internal thread of the vertical plate, and a bolt connected to the surface thread of the locking screw.
[0006] A connecting support plate is fixedly connected to the front of the mounting support plate, a limit spring is fixedly connected to the bottom of the connecting support plate, a rotating frame is fixedly connected to the front of the mounting support plate, a top limiting plate is hinged to the surface of the rotating frame, rotating columns are fixedly connected to the left and right ends of the mounting support plate, a connecting support rod is hinged to the surface of the rotating column, a locking nut is threaded to the surface of the rotating column, a bottom limiting plate one is fixedly connected to the surface of the connecting support rod, a connecting pillar is fixedly connected to the front of the bottom limiting plate one, and a bottom limiting plate two is fixedly connected to the front of the connecting pillar.
[0007] As a further improvement to the above solution, the number of the upright plates is set to two, and the two upright plates are symmetrically distributed on the left and right sides with the mounting support plate as the center. The locking screw is located on the front of the mounting support plate, and the bolt is located on the front of the mounting support plate.
[0008] With the above technical solution, the two upright plates are symmetrically distributed around the mounting plate. The locking screw and bolts work together to form a two-way locking mechanism. Precise alignment is not required during installation. The fastening force on both sides can be adjusted synchronously by rotating the locking screw. The operation time for a single person is shortened to that of the traditional structure. The symmetrical distribution of the bolts ensures uniform force distribution, avoids deformation of the mounting plate due to unilateral load, and improves torsional strength.
[0009] As a further improvement to the above solution, the number of bolts is set to two, and the two bolts are symmetrically distributed with the locking screw as the center. The bottom of the rotating frame is in contact with the top surface of the top limiting plate.
[0010] As a further improvement to the above solution, the top limiting plate is located on the front of the mounting plate, and the number of the rotating column and connecting rod is set to two, with the two rotating columns and connecting rods symmetrically distributed on the left and right sides with the mounting plate as the center.
[0011] Through the above technical solution, the top limiting plate is hinged by the rotating frame, and the bottom limiting plates one and two are linked with the connecting support column and the connecting rod. The angle of the limiting plate can be adaptively adjusted according to the curvature of the conductor, reducing the need for on-site grinding or shim compensation, and adapting to conductors of different diameters. The rotating column and the connecting rod solve the installation problem in complex terrain.
[0012] As a further improvement to the above solution, the bottom limiting plate is located at the bottom of the mounting plate, the bottom limiting plate is located at the bottom of the top limiting plate, and the connecting column is located at the bottom of the top limiting plate.
[0013] As a further improvement to the above solution, the second bottom limiting plate is located on the front of the first bottom limiting plate, and the number of connecting pillars is set to two, with the two connecting pillars symmetrically distributed on the left and right sides with the first bottom limiting plate as the center.
[0014] As a further improvement to the above solution, the second bottom limiting plate is located at the bottom of the top limiting plate, and the surface of the locking nut is in contact with the surface of the connecting rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model, by setting a limiting spring linked to the top limiting plate and setting two layers of bottom limiting plates, provides pre-tensioning force to automatically compensate for displacement caused by thermal expansion and contraction of the conductor. The double-layer bottom limiting plates form a double insurance to prevent the conductor from coming off due to wind vibration or accidental impact. Through innovative designs such as symmetrical adjustment, elastic limiting, and modular linkage, it solves the problems of cumbersome installation, single limiting, and poor environmental adaptability of traditional tension string structures. It has the advantages of high efficiency, stability and economy, and provides technical guarantee for the rapid deployment and long-term safe operation of transmission lines.
[0017] This utility model adopts standardized interfaces for components such as connecting support plates and rotating frames. The limit plate and connecting support are designed separately, so only the limit plate or connecting support needs to be replaced for different specifications of conductors, without the need for overall reconstruction. The modular structure supports lateral expansion and can be spliced with multiple sets of tension string units, adapting to UHV power transmission scenarios. The top of the mounting support plate is equipped with a connecting lifting ring, and the bottom limit plate is made of rust-proof material. The lifting ring supports hoisting or suspended installation, making it suitable for complex environments such as high mountains and water areas. The surface of the limit plate is galvanized, which improves corrosion resistance by several times and allows for long-term use in harsh climates such as high humidity and salt spray.
