Problems solved by technology
[0004] The present invention overcomes the technical problem of concentrated stress and unreasonable stress at the connecting parts of the tower body and the pillar insulator series in the existing power transmission line emergency repair, and provides a force transmission mechanism for improving the local stress state of the iron tower bar. On the cross section of the tower body connected with the post insulator series, the design is reasonable and the structure is simple, which effectively solves the problem of concentrated force on this part and one-sided force, improves the force and reduces the weight of the tower
To overcome the technical problems of concentrated force and unreasonable force in the connection between the tower body and the post insulator series of the existing transmission line repair tower, and to provide a force transmission mechanism for improving the local force state of the iron tower rods

Description
Technical field: [0001] The invention relates to the field of fasteners and mechanical force transmission, in particular to a power transmission iron tower. Background technique: [0002] The emergency repair tower is a kind of emergency repair equipment used to temporarily erect the line when the tower collapse accident occurs on the conventional transmission line. Generally, the emergency repair tower is designed with a cross-arm structure, which is used to mount the ground wire, resulting in a high height of the emergency repair tower, and the connection structure between the cross-arm and the tower body is complex and has many specifications. In response to these shortcomings, some emergency repair towers use composite insulated cross arms or post insulator strings to replace traditional steel structure cross arms. The cross arm or post insulator string is the intermediate structure connecting the wire, ground wire and the tower body, which transmits the self-weight of ...
