Abstract

A single column type derrick of an electric transmission line is formed by connecting a suspension base, a standard knot and a pulley in sequence. The two ends of the standard knot are provided with conical end joints. The standard knot and the end joints are formed by a plurality of circular pipe joint bodies. Each joint body is formed by winding carbon fiber reinforced resin matrix composite materials, and the adjacent joint bodies are connected through a flange. Each flange comprises a core pipe with the side wall provided with a groove and a tubular inner plate arranged on the top of the core pipe, wherein bolt holes are formed inside the groove in the circumferential direction, a boss is arranged between the inner plate and the core pipe, the inner plate is sleeved with the joint bodies, the inner plate and the joint bodies are bonded together through glue, and the end of each joint body abuts against the corresponding boss. The derrick is made of the carbon fiber reinforced resin matrix composite materials and is high in strength and light in weight.

Description

technical field [0001] The invention relates to a holding pole of a power transmission line, in particular to a single column type holding pole of a power transmission line. Background technique [0002] The structure type of the holding pole used for the erection of the transmission line construction tower is generally a single column type. This kind of holding pole has light weight, good longitudinal stability, high bending strength, and small lateral deformation; steel pole materials are commonly used. Made of standard sections and aluminum standard sections, the density of steel is high, and the poles made of them are heavy, which is not conducive to assembly, disassembly and handling. The density of aluminum material is relatively small, and the weight of the steel flange after the pole is connected increases, which is not convenient for manual installation and transportation, especially for the construction of transmission lines in complex mountainous areas and areas w...
