Abstract

The invention provides a self-lifting tower erecting device and method based on a semi-rigid composite material tower head crane, and relates to the technical field. The device comprises a tower cranebasic section, a plurality of tower crane standard knots led in/out from the lower part of the tower crane basic section one by one, a semi-rigid composite material tower head arranged above the tower crane basic section, a tower head crane mounted on the tower head, and a hydraulic lower jacking system for lifting or lowering the tower crane basic section, and the semi-rigid composite material tower head comprises a cross arm serving as a double-horizontal suspension arm. According to the device, through a mechanical self-lifting tower erecting mode, the composite material tower head cross arm is used as the double horizontal lifting arms, the double arms are mutually balanced, double hooks can independently work or symmetrically lift, the lifting work efficiency is high, and the liftingarm dismounting procedure is omitted, so that the construction work efficiency is high, and the risk is small.

Description

technical field [0001] The invention relates to a vertical tower device and method, in particular to a self-elevating vertical tower device and method based on a semi-rigid composite material tower head crane. Background technique [0002] Generally, the pole and tower conductors of double-circuit transmission lines are arranged vertically. As a classic straight tower type of double-circuit transmission lines, this tower type is widely used in transmission lines of various voltage levels. It is characterized by symmetrical arrangement of wires and balanced structural force. [0003] The traditional way of erecting wire towers is highly dependent on labor, low in efficiency, and highly dangerous. [0004] Based on this, this application is made. Contents of the invention [0005] In order to solve the above-mentioned defects in the prior art, the present invention provides a self-elevating vertical tower device and method based on a semi-rigid composite tower head crane, ...
