Description
Technical Field
The application relates to the field of power transmission, in particular to a composite suspension yoke plate with a vibration absorption function.
Background
The overhanging yoke plate is used as a part of a power transmission line and is widely applied to the design of a power transmission tower. The wires on the transmission line are connected through the hanging yoke plates to form a power transmission channel, and electric energy is transmitted from the power plant to the user terminal, so that the stability and reliability of power supply are ensured. The traditional power transmission tower structure is generally composed of steel pipes or angle steel, and the hanging yoke plate structure can replace the traditional structure, so that the larger space utilization rate and lighter structure weight are provided, and the requirement on a foundation is reduced. The suspension yoke plate power transmission tower has the advantages of simple structure, convenient construction, strong wind resistance and the like, and is widely applied to the construction of power transmission lines.
At present, most of the main hanging yoke plates in China are steel truss hanging yoke plates, and the hanging yoke plates have higher strength and rigidity, but have the following problems:
1) Easy rust oxidation: the steel is susceptible to corrosion such as oxidation and rust, especially in humid, high humidity and high salinity environments.
2) Stability is poor: due to the structural characteristics of the suspension yoke plate, the suspension yoke plate is easy to generate unstable phenomenon in the process of bearing force. When subjected to large compressive or extrusion forces, the depending webs may lose stability, resulting in structural failure.
3) Easy vibration: the problem of vibration of the steel truss overhang yoke is also a common drawback. When the suspension yoke plate is subjected to external force or vibration, the suspension yoke plate is easy to generate resonance phenomenon, so that the structure is damaged or unstable
4) The maintenance cost is high, and the steel suspension connecting plates are easy to corrode and damage and need to be maintained and replaced regularly. In the maintenance process, rust removal, corrosion prevention and other treatments are required, so that the maintenance cost and the workload are increased.
5) The weight is larger: the steel is heavier than other materials, which makes the dead weight of the steel hanging connection plate larger and increases the load of the transmission line.

In use, when the structure is subjected to external horizontal vibration or impact load, the transverse vibration absorbing block moves along with the vibration of the structure, and the horizontal vibration of the structure is restrained by the inertial force and the damping force. When the structure is subjected to external vertical vibration or impact load, the longitudinal vibration absorbing block moves with the vibration of the structure, and the vertical vibration of the structure is suppressed by the inertial force and the damping force.
