Automatic traction system for large-size tower crane mounting and dismounting standard knot and traction method thereof

Abstract

The invention discloses an automatic traction system for a large-size tower crane mounting and dismounting standard knot. The automatic traction system comprises a single-rail introduction beam, wherein a traction mechanism is arranged at the tail end of the single-rail introduction beam; a traction steel wire rope is wound on the traction mechanism in a shuttling manner; the long rope end of the traction steel wire rope is fixed on an introduction trolley through a rope clamp after rounding a guide pulley at the head end of the single-rail introduction beam; the short rope end of the traction steel wire rope is connected with a rope tightening device of the introduction trolley; the rope tightening device effectively fastens the traction steel wire rope; an introduction trailer is hung on the lower part of the introduction trolley; two sides of the introduction trailer are connected with hook parts on two sides of a jacking hanging hook. According to the automatic traction system for the large-size tower crane mounting and dismounting standard knot, a series of shortcomings, such as difficulty in operation of a mounting and dismounting worker, high high-altitude working risk of an operator during the mounting and dismounting work and low efficiency of the mounting and dismounting work, in manual traction adopting an existing general tower crane standard knot mounting and dismounting introduction system can be overcome.

Description

technical field [0001] The invention relates to the technical field of an automatic traction system for mounting and dismounting parts of a tower crane, in particular to an automatic traction system for installing and dismounting a standard section of a large tower crane, and particularly relates to its mechanical connection structure and automatic traction method. Background technique [0002] The current general introduction system for installation and disassembly of standard sections of tower cranes uses manpower for traction. The standard section traction system is mainly composed of two introduction beams and an introduction trolley. The introduction device for the installation and disassembly of the standard section of the tower crane that is more common now is composed of three major components: the jacking hook, the introduction beam, and the introduction trolley. Hook the imported trolley, use bolt pins to connect the imported trolley to the standard section, and th...
