Abstract

The invention provides a circular pipe type inner suspended holding pole, and belongs to a holding pole used for group erecting of a transmission tower. The holding pole is formed by connecting a suspended base, a lower segment, a straight line segment, an upper segment and a knuckle arm component in sequence by bolts, wherein the straight line segment is formed by connecting a plurality of standard segments in sequence by bolts; and the straight line segment, the upper segment and the lower segment are formed by welding circular pipes. The holding pole has the advantages of light weight, good mechanical property and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to the technical field of electric power construction machinery and equipment, in particular to a pole used for erecting transmission line iron towers. Background technique [0002] The existing poles used for erecting transmission line iron towers are mainly made of angle steel / angle aluminum. The poles of this type of structure have the disadvantages of heavy weight and poor mechanical properties. [0003] The Chinese patent literature discloses a "special pole for the invention of tower assembly" (CN201016232Y), which is composed of oblique materials fixedly connected between a plurality of rod-shaped main materials to form the main body of the pole, and the oblique materials or / and main materials are hollow tubing. It has not yet reached the practical and perfect stage. Contents of the invention [0004] The object of the present invention is to provide a circular tube type inner suspension pole with light weight, good me...
