The invention discloses a combined sleeve for a double-nut bolt. The combined sleeve comprises a sleeve body (1) and a conversion chuck (2); the sleeve body (1) is provided with an inner cavity (1-4) for containing the conversion chuck (2); the outer surface of the conversion chuck (2) is matched with the inner surface of the inner cavity of the sleeve body (1); and the inner surface of the conversion chuck (2) is matched with the outer surface of a to-be-constructed nut. The combined sleeve can be used for different double-nut bolt specifications of a power transmission iron tower, the sleeve body and the conversion chuck can be flexibly combined, and the combined sleeve can adapt to the large-range bolt specifications only through a small number of assemblies; the construction problem of a single nut of a double-nut structure can be effectively solved, and meanwhile the reliable construction requirement of the large-torque bolt can be met; and the structure is simple, using is convenient, and carrying is convenient.
Description
technical field [0001] The invention relates to the technical field of power transmission tower construction, in particular to a combination sleeve used for double cap bolts of power transmission towers and a method of use thereof. Background technique [0002] With the development of the power grid, the voltage level of transmission lines continues to increase, and the types and numbers of transmission towers continue to increase. At the same time, the society's demand for power supply reliability is increasing, and higher requirements are placed on the operation safety of transmission towers. The transmission tower is a truss structure connected by bolts. Under the action of alternating loads such as galloping and strong gusts, the loosening and falling off of bolts on the tower has become an important cause of transmission line failures. [0003] In order to reduce the failure of transmission towers caused by loose bolts, double cap bolts are often used for connection in ...
